1 General Situation of Surveyed Regions The Guangxi Zhuang Autonomous Region is located in southern China, north latitude
20542623, east longitude 1042911204, with the Tropic of Cancer running across its central area.
There are 14 prefecture-level cities under the region's jurisdiction and Nanning is its capital. Its
land area is 23.67 square kilometers, 2.5% of the national land area. The region adjoins the Beibu
Gulf in the south, faces to the Hainan Province across the sea, borders Guangdong in the east,
Hunan in the northeast, Guizhou in the northwest, Yunnan in the west, and is adjacent to Vietnam
in the southwest. It is the most convenient sea route in southwest China, playing an important
role in the economic ties between China and Southeast Asia.
The terrain in Guangxi is high in the northwest, slanting to the southeast, surrounded by
ranges of huge mountains and dotted with canyons. Due to the surrounding high mountains, a
flat basin-like internal region with breaches in the margins, and flat ground in most central and
south places, it is called Guangxi Basin.
There are lots of rivers running in Guangxi, mostly slant with the terrain from the northwest
to the southeast, forming a tree-like river system with the main watercourse Hongshuihe River -
Xijiang River across central Guangxi and tributaries in the two sides. The Pearl River system is
the largest in Guangxi, with its drainage area accounting for 85.2% of the total area of Guangxi.
The Yangtze River system distribution is in northeast of Guangxi, with its drainage area
accounting for 3.5% of the total area of Guangxi. A single sea-toward river system is mainly
distributed in north, with its drainage area accounting for 11.3% of the total area. Larger rivers,
such as Nanliu River, Qinjiang River and Beilun River, empty into the Beibu Gulf.
Guangxi is located in low latitudes, with the Tropic of Cancer running across its central
region, tropical ocean on the south, the Nanling Mountain Range in the north, and the
Yunnan-Guizhou Plateau to its west extension. As the transition zone from Yunnan-Guizhou
Plateau to the southeast coastal hills, Guangxi possesses terrain characteristics of high rims and
low center, a basin shape, numerous mountains and few plains. The Karst landform spreads
widely, account for 37.8% of the total area of the Guangxi, concentrated in its southwest,
northwest, middle part and northeast areas.
Guangxi lies in the middle and south Asian tropical monsoon climate zones, with a warm
1
climate and abundant heats. The annual average Region temperatures are between 16.5 ~ 23.1 C.
The annual average temperature in about 65% of the region is above 20.0 C.
Guangxi is one of the provinces with most rainfall in China. The annual Region
precipitations are between 1080 ~ 2760 mm, mostly between 1300 ~ 2000 mm. The geographical
distribution features are more in the east and less in the west; more in the hills and mountains,
less in the river valleys and plains; more in the windward slopes and less in the leeward slopes in
the summer, etc. Due to the effect of alternating winter and summer monsoons, the seasonal
distribution of rainfall of Guangxi is uneven, with an obvious distinction between the dry season
and the wet season. April to September is the rainy season, with a total rainfall accounting for
70% ~ 85% of annual rainfall; October to March is the dry season, with a total rainfall
accounting for only 15% ~ 30% of annual rainfall.
Located in the subtropical monsoon climate zone, Guangxi has its hot season and rainy
season in the same period. Its tree growth exceeds three to four times the national average, an
important part of the southern collective forest region, with a critical ecological location,
superior natural conditions and abundant species, all conducive to the development of forestry.
The areas of plantation, economic forests and fast-growing forests of Guangxi rank first in the
nation, and the annual commercial timber production accounts for one seventh of that in the
whole country. The area's forest land area is 226 million mu, 63.5% of the total land area, nearly
three times that of agricultural land and the fifth largest in the nation. Its collective forest land
area is 210 million mu, the third largest in the nation. There are 8354 species of vascular plants
in Guangxi, the third most in the nation. With 884 kinds of terrestrial wild vertebrates, Guangxi
is one of the provinces with numerous wild animals in China. The more than 1000 kinds of
plants and animals in the region are of high economic value, among which there are more than
100 rare trees suitable for cultivation.

2 Survey Purpose Stora Enso is the global rethinker of the paper, biomaterials, wood products and packaging
industry. We always rethink the old and expand to the new to offer our customers innovative
solutions based on renewable materials. The company's "Code of Conduct" covers three key
areas: responsible business, caring for people, and caring for the environment.
Kemira is a global chemical company that serves customers in water intensive industries. It
provides professional technology and chemicals to help customers improve the efficiency of
water resources, energy and raw materials. Water use efficiency and protection of water
resources are the center elements of Kemiras strategy.
In 2013, Stora Enso Corporate and Kemira decided to jointly implement the "Water
Stewardship - Shared Value Creation" project in Guangxi. The project is invested, constructed
and implemented jointly by Stora Enso and Kemira, aiming at responsible protection of water
resources in the incorporated communities. It brings together Kemiras world-leading expertise
water quality and quantity management, Stora Enso's professional knowledge on plantation
cultivation and management, as well as Guangxi local communities practical knowledge and
experience in water resources issues. The project improves the abilities in the area to protect and
manage water resources, and enhances the societys understanding of water issues. The project
was launched in the end of 2013 and lasts until the end of 2015. It includes four modules of
baseline survey, water monitoring, pilot projects and awareness building communication.
This baseline survey is the first module of the project to be launched and implemented. It
includes surveys on drinking water and agricultural water, with the aim to understand the sources
of domestic water for the local people, the condition of water quality, quantity and usage, the
processes of sewage and water use, the current environmental conditions and production
situations in the villages, as well as prospects for future development, including projects already
planned and implemented by the villagers. Through the research, real and effective essential data
was obtained, which helped the project team to comprehend the current situation, actual
difficulties and the needs of the local communities. Consequently, it will help the team in select
and build an appropriate and ideal pilot project and popularize basic knowledge about water
source conservation and scientific usage of water.

3 Survey Process, Method and Target
3.1 Survey Schedule
January, 2014: Preparation for the baseline survey.
February, 2014: Conduct pilot survey in Nanning Region, including field survey, collecting
questionnaire, data analysis, and preparing summary report.
March, 2014-June, 2014: Conduct field survey and collect questionnaire in Yulin Region,
Beihai Region and Qinlian Region; collect questionnaire from NGO at the same time.
June, 2014-August, 2014: Analyze the survey data, prepare survey report, and finish
translation and text check.
3.2 Survey questionnaire
According to the survey purpose and surveyed target, three different types of questionnaires
are used for this survey: a questionnaire on ecological environment and water usage safety in
forest community (for the villagers), a questionnaire on basic village situation (for natural village
leaders or villager group leaders), and a questionnaire on water resource-related issues (for
relevant government departments and non-governmental organizations).
3.2.1 Survey on Ecology and Water Usage Safety in the Forest Community
The survey method is a questionnaire form. The survey content on villagers' views of
ecological environment and water usage safety is divided into five main aspects, including 49
items:
(1)Basic Village Information
14 items in total, including: family size by age; literacy of family members; family annual
income; main source of income; breeding species and quantity; number of fields and crops
species; woodland area and plant species; fish pond area and breeding; farmland fertilizers and
quantity; pesticide quantity applied to farmlands; road types in living quarters; garbage
processing mode in living quarters; residence environment; main fuel types.
(2)Drinking Water (in this report drinking water refers to domestic water)
10 items in total, including: sources of drinking water; well water types; whether the
drinking water has been treated and treatment methods; whether the drinking water is in line with
4
the national water quality standards and judgment criteria; level of satisfaction with the current
situation of drinking water and reasons for dissatisfaction; domestic water consumption; drinking
water supply and shortage time; change in water quality compared with that of ten years ago and
the reasons behind the change; change in water quantity compared with that of ten years ago and
reasons behind the change; whether government departments or village committees have plans to
improve the water quality.
(3)Agricultural Water
8 items, including: livestock drinking water source; irrigation water source; level of
satisfaction with current agricultural water quality and reasons for dissatisfaction; agricultural
water supply and shortage time; main irrigation modes; proportion of farmland with artificial
irrigation; main uses of irrigation water; whether there are plans to improve the irrigation
methods.
(4) Domestic Sewage
8 items in total, including: toilet types; domestic sewage treatment ways; domestic sewage
discharge ways; wastewater discharge destinations; whether sewage discharge points and
drinking water sources are from the same water body; whether there are plans to improve the
sewage treatment methods; water quality of rivers near the village; main pollution sources of
water body.
(5) Opinions and Advices
9 items in total, including: whether the people are satisfied with the existing life and reasons
for dissatisfaction; what rural environments need to be improved; what is the biggest problem in
rural development; the effort that one is willing to invest in the improvement of water conditions
with the aid of the government; the effort that one is willing to invest in domestic sewage
treatment with the aid of the government; whether one is willing to use slurry from biogas
fermentation to irrigate farmland and the reasons; whether one is willing to use residue from
biogas fermentation as fertilizer and the reasons; plans for increasing income; other opinions and
suggestions.
3.2.2 Survey on basic village situation
In order to guarantee the credibility of the survey data, cadres of sampled natural villages
5
are asked to fill out a form regaring the basic situation of their village. The form's content mainly
includes: population information, production situation, main source of livelihood, water supply
and drainage, government policies and programs in rural development and construction,
government policy project on conservation and management of drinking water resources,
environment-related problems that are reflected most by the village mass, development direction
and plans for the village in the next three or five years. The investigation content is basically the
same as the questionnaire content of the survey on ecological environment and water usage
safety for the villagers. This way it is possible to verify the villagers truthfulness regarding the
questionnaire content via a higher level.
3.2.3 Survey on Issues Related with Water Resources
The survey can be divided into two aspects: one is the sample policies and views of the
town government on water resources; the other is the policies and views of the NGOs on water
resources.
The survey is conducted in the form of a questionnaire, and its content mainly includes 11
items as follows:
1) What policy and plan regarding water source conservation and cleaning does the
government implement? (for government authorities); Currently, what activities of
water resource protection and management does your organization partake in? What are
the specific practices? (for NGOs)
2) Currently, what major problems in water supply exist in the rural and urban areas?
3)
Currently, what major problems in sewage discharge exist in the rural areas?
4) How is the quality of surface water and underground water in the rural areas? What are
the main pollutants?
5) With regard to conservation of sources of rural drinking water, what should be taken
into consideration?
6) As for helping rural and urban residents test the quality of their drinking water, what
testing items should be made as priority?
7) What equipment or technology is recommended in order to improve the quality of
6
drinking water?
8) What equipment or technology is recommended to be used for disposing rural sewage?
9) Do you think that the villagers are in urgent need to improve water supply conditions or
drainage conditions?
10) What problems may exist in carrying out water supply and sewage disposal projects in
the rural areas?
11) What do you think is the enterprise's responsibility and its role in local water resources
protection and management?
3.3 Survey Target
3.3.1 Villagers
The surveyed area is divided into 4 Regions in accordance with SEGXs forestland
management: the Nanning Region (including Nanning City and Chongzuo City), the Yulin
Region (including Yulin City, Guigang City and Wuzhou City), the Beihai Region (Beihai City)
and the Qinlian Region (Qinzhou City).
The surveyed target was chosen at random. First the forestland administrator in each Region
tallied and reported the essential data, and then drew the minimum representative number for the
survey to be valid (the number of natural villages) by using a random sampling method of
numerical statistics. After that it was distributed proportionally to natural villages, village
committees, and towns in each Region. 8 households of villagers in each natural village were
chosen randomly for the survey. Please refer to Table 3-1 for specific survey targets and number
of targets.

4 Survey Result and Analysis of Questionnaire for Villagers
4.1 Basic Information
4.1.1 Family Composition and Education Level of Surveyed Target
4.1.1.1 Nanning Region
Out of households surveyed, the primary age groups were youngsters and middle-aged
persons (Figure 4-1). The age groups of 41-60, 20-40, and below 20 accounted for 31.62%,
40.44%, and 19.12% respectively, which took up 91.18% of the total population surveyed. The
education level of family members was relatively low (Figure 4-2), among which only 12.27%
had received a senior high school education. Those who just had junior middle or elementary
education took up 49.55% and 34.09% respectively. This means 83.64% of the villagers
surveyed received only either elementary or junior middle school education.

4.1.1.2 Yulin Region
Out of the households surveyed, the age groups of 41-60, 20-40, and below 20 accounted
for 25.81%, 33.75%, and 27.69% respectively, which took up 87.25% of the total population
surveyed (Figure 4-3). The family members who received senior high school education, junior
middle and elementary education took up 12.26%, 51.41% and 32.20% respectively (Figure 4-4).
This means 85.61% of the villagers surveyed received only either elementary or junior middle
school education - the lowest educational level among the 4 surveyed Regions.

4.1.1.3 Beihai Region
Out of the households surveyed in theBeihai Region, the age groups of 41-60, 20-40, and
below 20 accounted for 23.60%, 35.63%, and 27.18% respectively (Figure 4-5). The family
11
members who received junior middle and elementary education took up 78.77% of the total
population surveyed (Figure 4-6), and those who received senior high school education
accounted for 17.32% - the highest among the 4 surveyed Regions.

4.1.1.4 Qinlian Region
Out of households surveyed in the Qinlian Region, the age groups of 41-60, 20-40, and
below 20 accounted for 23.26%, 35.19%, and 28.47% respectively. The young working force
was quite abundant, but their educational level was generally low, with over 80% of villagers
receiving junior middle and elementary education.
Figure 4-7 Age Structure in the Qinlian Region
13
Figure 4-8 Education Level in the Qinlian Region
4.1.1.5 Summary
The overall major age group of the survey was 20-60 years old, or about 60% of the total
surveyed population. The proportion of Nanning in this age group was the largest, reaching
72.06%, showing that most households had adequate labor force. The villagers generally had a
low level of education, with 80% only having received junior middle school or elementary
education. This directly affects the quality, job skills and family income of the villagers.

Figure 4-9 Overall Age Structure in Survey Plot
Figure 4-10 Overall Education Level in Survey Plot
4.1.2Family Average Annual Income and its Composition
4.1.2.1 Nanning Region
The average annual gross income of more than half of households (57.89%) was less than
15
10, 000 Yuan (Figure 4-11), among which 29.82% had an average annual income less than 5,000
Yuan, indicating that the rural economic level of the Nanning Region was still relatively low.
Figure 4-11 Family Average Annual Incomes in the Nanning Region
It can be seen from the Component of Family Income (Figure 4-12) that the revenue from
working away from home, agricultural plantation, and forestry took up 27.37%, 40.00% and
10.53% of the family income respectively, totaling to 77.9%. Those who raised poultry usually
chose chickens, ducks, and geese, which accounted for 89.35%. Nevertheless, 93.18% of the
families who kept poultry did it for their own use, instead of trying to sell them to generate more
family income.
16
Figure 4-12 Component of Family Income in the Nanning Region
4.1.2.2 Yulin Region
In the Yulin Region, the villagers' family income was very low: the amount of households
with an average annual income less than 5,000 Yuan reached 57.84% (Figure 4-13). Thus it can
be seen that the region's rural economic income is the main factor restricting the improvement of
villagers education and quality. The interdependency between economy and education causes the
villagers to mainly partake in physical work with low technology.
Figure 4-13 Average Family Annual Income in the Yulin Region
It can be seen from the Component of Family Income (Figure 4-14) that the revenue from
working away from home, agricultural plantation, and forestry took up 37.13%, 34.72% and
9.63% of the family income respectively, totaling to 80%. Those who raised poultry usually
chose chickens, ducks, and geese, which accounted for 99.97%. Nevertheless, 72.65% of the
families who kept the poultry did it for their own use.
17
Figure 4-14 Component of Family Income in the Yulin Region
4.1.2.3 Beihai Region
The households in the Beihai Region with family annual income of 5,000-10,000 Yuan and
below 5,000 Yuan accounted for 21.45% and 73.01% respectively (Figure 4-15), taking up
94.46% of the total households surveyed. Thus it can be seen that the rural economic income in
this Region was relatively low.

It can be seen from the Component of Family Income (Figure 4-16) that the revenue from
working away from home, agricultural plantation, and forestry took up 33.63%, 35.26% and
9.95% of the family income respectively, which totaled to 75.42%. Those who raised poultry
usually chose chickens, ducks, and geese, which accounted for 78.84%.
Figure 4-16 Component of Family Income in the Beihai Region
4.1.2.4 Qinlian Region
The family annual income in the Qinlian Region is generally lower than 5,000 Yuan,
accounting for 86.88% of the total surveyed (Figure 4-17). Working away from home,
agricultural plantation, and forestry were the main sources of income (Figure 4-18), which
accounted for 86.02% of the villagers' income, indicating that the rural economy in this Region
was relatively low, mainly composed of traditional industries.
19
Figure 4-17 Average Family Annual Income in the Qinlian Region
Figure 4-18 Component of Family Income in the Qinlian Region
4.1.2.5 Summary
The economical conditions of the villagers in the four surveyed Regions were not so good,
and the family income of the villagers in the Yulin and Beihai Regions was rather low. Taking the
proportion of annual family income below 5000 Yuan as an example, the proportion of the Yulin
Region was 57.84%, that of the Beihai Region was 73.01%, the Qinlian Region 86.88%, and the
Nanning Region only 29.82%. The family income in these Regions could be summarized as
20
Nanning Region > Yulin Region > Beihai Region > Qinlian Region. In general (Figure 4-19 and
4-20), the family annual income of more than 90% of the villagers was less than 10,000 Yuan.
About 90% of the income was from work away from home, agricultural plantation, fish breeding,
poultry raising and forestry.

4.1.3 Land Utilization
4.1.3.1 Nanning Region
21
In terms of land type among the surveyed villages, agricultural land took the lead.
Agricultural land and forest land occupied 744.8 mu and 253.5 mu correspondingly (Figure
4-21). Among agricultural land, paddy fields took up 9.8%, while the remaining 90.2% was dry
farmland, indicating insufficient water sources in the Region. Wide-spread Karst landscape, poor
water retention ability of forests in the rocky mountains, heavy surface water leakage and soil
erosion all together make it a Region that suffers from a severe water shortage. Rice was grown
in paddy fields, and sugarcane, corn, and cassava were generally planted in dry farmland. Forest
land was commonly used to plant eucalyptus and Chinese red pine, accounting for 50.00% and
36.84% respectively; other usually grown plants included Australian red cedar, star anise, cedar,
bamboo, etc. It can be concluded that the villagers living in the forest areas are accustomed to
growing trees. Land used for fishery purposes was very rare, mainly resulting from scarcity of
water.
Figure 4-21 Land Utilization Type in the Nanning Region
4.1.3.2 Yulin Region
Agricultural land and forest land of the surveyed villagers occupied 1361.48 mu and 3127
mu correspondingly (Figure 4-22). Among agricultural land, paddy fields took the largest part
and was planted with rice. Dry farmland was mainly planted with peanuts and corn. Forest land
was commonly used to plant eucalyptus and pine, accounting for 65.15% and 13.64%
respectively; other grown plants included litchi, longan, tea-oil trees, star anise, etc. It can be
concluded that the villagers living in forest areas are accustomed to growing trees. Land used for
fishery purposes was very rare, only 28 mu of land among the surveyed land types. Common fish
22
included grass carp and bullhead.
Figure 4-22 Land Utilization Type in the Yulin Region
4.1.3.3 Beihai Region
The land type in the surveyed villages in the Beihai Region was mainly forest land,
accounting for 3831.9 mu (Figure 4-23); agricultural land accounted for more than 2000 mu, of
which the ratio of dry farmland and paddy field was close to 1:1. The main paddy field crop was
rice. The crops planted on dry farmland were mainly sugarcane, corn and peanuts. All forestlands
are used to plant eucalyptus. Differing from the other three Regions, the villagers in this Region
are not good at fish farming; the total fish pond area was small, only 115.6 mu.
Figure 4-23 Land Utilization Type in the Beihai Region
4.1.3.4 Qinlian Region
23
The major land type in the Qinlian Region was forest land (Figure 4-24), which accounted
for over 95%, and the common tree species was eucalyptus. Comparatively, the amount of
agricultural land was small, the areas of paddy fields and dry farmlands were almost the same,
and the area of fish ponds was about 1% of the total area.
Figure 3-24 Land Utilization Type in the Qinlian Region
4.1.3.5 Summary
On the whole, the main land utilization type in the four Regions, except Nanning, was forest
land (Figure 4-25), the proportion of which was more than 60%. Agricultural land accounted for
about 35%, with equal paddy field and dry land areas. The total area of fish ponds was very
small, only about 1%. Among the four Regions, the Nanning Region had the smallest proportion
of forest land, while the Qinlian Region had the largest. (Note: this survey was mainly for
villages around the forest areas, so the land utilization type was mainly woodlands. This survey
only reflects land utilization of villages around forest areas and does not represent rural land
utilization in all parts of Guangxi.)
24
Figure 4-25 Overall Land Utilization Type in the Surveyed Regions
With regard to land type, farmland took the lead in the Nanning Region, while forest land
was most common in the Beihai Region. The ratio of paddy fields and dry farmland in the Yulin
and Beihai Regions was close to 1:1, while that in the Nanning Region was 1:9, affected by its
Karst landform and water storage function of the rocky mountain forests. Eucalyptus
plantatations accounted for the largest proportion of forest lands; in the Nanning Region it was
about 50%, in Yulin it was about 65%, and in Beihai it was close to 100%. Besides Eucalyptus,
common tree species include pine, Australian red cedar, star anise, cedar, bamboo, litchi, longan
and tea-oil tree are also.
4.1.4Use of Fertilizers and Pesticides
4.1.4.1 Nanning Region
The amount, types, and proportions of fertilizers and pesticides used by the villagers were
not regulated; therefore most families just used them according to their crop type and past
experience. The amount of fertilizers used was from 40 kg to 150 kg per mu, depending on types
of crop (Figure 4-26). In general more than 50 kg of fertilizers was used per mu, only in 2.44%
of the Region less than 50 kg of fertilizers was used to every mu of land. The reason could be
that this was a sugarcane production region, so increasing the amount of fertilizers would
improve production.
25
The usage of pesticides was commonly between 0.5 kg and 1 kg or above 2.5 kg/mu, or
varying in accordance with the types of crop (Figure 4-27). Those who did not use pesticides
were villages with a lower income level. The amount of pesticides used was generally above 2.5
kg/mu, and most of the households (50%) used 5 to 10 kg/mu. The reason may be that sugarcane
was the staple crop in this Region, and increasing fertilizer application would improve
production.
Figure 4-26 Usage of Fertilizers in the Nanning Region
Figure 4-27 Usage of Pesticides in the Nanning Region
26
4.1.4.2 Yulin Region
Over 90% of the villagers in Yulin Region used less than 150 kg of fertilizers for every mu
of land, in accordance with different crops (Figure 4-28).
The use of pesticides in over 70% of the Region was less than 1 kg/mu, varying in
accordance with the types of crop (Figure 4-29). Those who did not use pesticides were villagers
with a lower income level, while villagers who used larger quantities of pesticides were richer.
However, massive use of fertilizers and pesticides in areas with heavy soil erosion would exert
an influence on water quality that was too significant to ignore.
Figure 4-28 Usage of Fertilizer in the Yulin Region
27
Figure 4-29 Usage of Pesticide in the Yulin Region
4.1.4.3 Beihai Region
The amount of fertilizers used in the Beihai Region was usually less than 100 kg per mu
(Figure 4-30), less than that in the Nanning and Yulin Regions. This resulted from major
application of organic fertilizers and less chemical fertilizers in the Region. It is worth
mentioning that in Shanglingjiao, Huapu Village, Fucheng Town, Hepu County and Beihai City,
the total amount of chemical fertilizers and organic fertilizers used were relatively large. The
fertilizers N, P, K and compound fertilizers were applied between 750-1000 kg/mu, and the
organic fertilizers could reach 1000 kg/mu.
The use of pesticides was commonly between 1-2.5 kg or 3-5 kg/mu, or varying in
accordance with the types of crop (Figure 4-31). Those who did not use pesticides were villagers
with a lower income level.
Figure 4-30 Usage of Fertilizer in the Beihai Region
28
Figure 4-31 Usage of Pesticide in the Beihai Region
4.1.4.4 Qinlian Region
The use of chemical fertilizers and pesticides in the Qinlian Region is quite similar with that
in the Beihai Region (Figure 4-32 and 4-33). The fertilizer application quantity in about 75% of
the Region was below 100 kg/mu. The reason for this was similar to the Beihai Region, which
was that organic fertilizers were used more, and more than 98% of the Region used pesticides in
amounts less than 5 kg/mu.
Figure 4-32 Usage of Fertilizer in the Qinlian Region
29
Figure 4-33 Usage of Pesticide in the Qinlian Region
4.1.4.5 Summary
More than 70% of the villagers in the Yulin, Beihai and Qinlian Regions used less than 100
kg/mu of fertlizers in a year, generally between 25-100 kg/mu, while the amount of fertilizers
used in the Nanning Region was far greater, with over 50% of the villagers using more than 150
kg/mu in a year. The main reason was that in the Nanning Region the soil suffered from poor
fertility maintenance, the nutrients were easily lost, and the farmers used lots of fertilizers in
sugarcane planting to raise the yield. Pesticide quantities in the four Regions also differed greatly.
Take, for example, the proportion of annual pesticide quantity > 3 kg/mu: in the Yulin Region it
was 10.19%, in the Beihai Region it was 38.35%, in the Nanning Region it was 33.33%, and in
the Qinlian Region it was 31.65%. Therefore, the Beihai Region took the lead in the amount of
pesticide application. Generally, the amount of fertilizer application was usually less than 100
kg/mu, and that of pesticides was usually less than 2.5 kg/mu, accounting for 78.33% and
73.74% respectively (Figure 4-34 and 4-35). In Regions with severe soil erosion, the impact of
substantial usage of fertilizers and pesticides on water quality was surely not to be ignored.
Unstandardized and irregular application of fertilizers and pesticides resulted in excessive loss of
nutrients, and was a major factor causing non-point source pollution of water bodies in the rural
areas.

4.1.5 Living Environment and Conditions
4.1.5.1 Nanning Region
In terms of living conditions, 51.52% of villagers had cement roads while 37.88% had
muddy roads; 9.09% and 1.52% of households had access roads and gravel roads respectively
31
(Figure 4-36). This means that the majority of the villagers had relatively convenient
transportation. Through the implementation of the Village Cleaning Project, 88.53% of the
garbage was collected to a central point for processing and only 11.48% was piled up arbitrarily.
Based on the above circumstances, 36.51% of the villagers thought their living environment was
clean, 50.79% thought of it as acceptable, and only 12.70% considered it dirty and disorganized
in some areas.
Fuels primarily used by the villagers were usually gas (41.05%) and wood (44.21%), while
those using methane and electricity only took up 9.47% and 4.21% respectively (Figure 4-37).
The reality of the villages was that as many left home to work elsewhere, the ones who stayed at
home were normally the elderly and children. Therefore the demand for fuel consumption was
relatively limited. In addition, although large amounts of firewood was used, the fuel
consumption rate was still low considering the popularity of gas.
Figure 4-36 Residence Road Type in the Nanning Region
32
Figure 4-37 Household Fuel Type in the Nanning Region
4.1.5.2 Yulin Region
In terms of living conditions, the residential environment was experienced as is shown in
the following chart (Figure 4-38). Although the Village Cleaning Project had been implemented,
only 22.93% of the villagers considered their living environment clean, 36% thought of it as
acceptable, 34.2% viewed that it was dirty and disorganized in some areas, and 9.87% held that it
was messy and dirty on the whole. The main types of fuel of the villagers were wood (61.77%)
and gas (20.88%). The use of straw and biogas were 11.68% and 4.96% respectively (Figure
4-39), so it could be said that wood was the main source of fuel.
33
Figure 4-38 Living Environment in the Yulin Region
Figure 4-39 Household Fuel Type in the Yulin Region
4.1.5.3 Beihai Region
In the Beihai Region, 30.47% of the villagers considered the environment clean, 40.83%
thought it could be called clean, 26.63% viewed that it was dirty and disorganized in some areas,
34
and only 2.07% held that it was messy and dirty on the whole (Figure 4-38), implying that most
villagers enjoyed a good living environment. The main fuel types of villagers were gas (29.68%)
and wood (50.09%), and use of straw and biogas were 10.02% and 8.51% respectively (Figure
4-39). The reality of the villages was that as many left home to work elsewhere, the ones who
stayed at home were normally the elderly and children. Therefore demand for fuel consumption
was relatively limited. In addition, although large amounts of firewood was used, the fuel
consumption rate was still low considering the popularity of gas.
Figure 4-38 Living Environment in the Beihai Region
35
Figure 4-39 Household Fuel Type in the Beihai Region
4.1.5.4 Qinlian Region
18.13% of the villagers thought of their living environment as clean (the lowest among the
four Regions), and 40% thought of the living environment as dirty and messy in some parts
(Figure 4-40) (the highest among the four Regions), This means that the environmental quality of
Qinlian needed to be improved. The amount of fuel consumption was basically the same as in the
other Regions, with wood taking the largest proportion (Figure 4-41).
36
Figure 4-40 Living Environment in the Qinlian Region
Figure 4-41 Household Fuel Type in the Qinlian Region
4.1.5.5 Summary
The proportions of villagers who considered their residential area as basically clean were:
Yulin Region 22.93%, Beihai Region 30.47%, Qinlian Region 18.13%, and Nanning Region
37
87.30%. The community environment in the Nanning Region was the best: on the whole, more
than 60% of the villagers thought of their residential environment as clean or relatively clean
(Figure 4-42). Regarding fuel sources (Figure 4-43), the fact that some villagers worked away
from home, thus reducing the family population, lessened family livestock farming (mainly for
private use). Thus the amount of livestock excrement and urine was small. Although most
households supported the use of biogas, biogas slurry and residue, biogas was still not very
popular. Overall, the rural environment was affected by the release of domestic sewage and
arbitrary piling of garbage, extensive use of fertilizers and pesticides, low educational level, and
of the lack of execution of environmental conservation measures.

4.2 Drinking Water
In this report, various water sources are mentioned. Because the scope of this survey is
mainly focused on rural area, the meanings of water sources may be different from general urban
water, and the specific meanings are as follows:
Tap water: water source is centralized water supply system for villages and towns; the water
is transported directly into the houses of villagers by pipelines.
Well water: water source is decentralized water supply wells; no centralized water supply
system; the water may be transported by pipelines or artificial lifting.
Mountain spring water: water source is decentralized mountain springs; no centralized
water supply system; the water may be transported by pipelines or artificial lifting.
River and stream: water source is decentralized rivers or streams; no centralized water
supply system; the water may be transported by pipelines or artificial lifting.
Reservoir: villagers take the water from reservoirs respectively; no centralized water supply
system; the water may be transported by pipelines or artificial lifting.
4.2.1 Sources of Drinking Water
4.2.1.1 Nanning Region
39
Out of the the surveyed villagers, those using tap water, well water, and mountain spring
water accounted for 35.09%, 42.11%, and 21.05% respectively. Only 1.75% used water sources
from rivers and streams (Figure 4-44). It can be concluded that tap water and well water were the
major types of drinking water for the villagers. For 63.16% of the people using water from wells
or mountain springs, the water was vulnerable to environmental pollution; especially mountain
spring water can be greatly impacted by the fertilizers and pesticides that are used in artificial
forests. 61.29% of the villagers' wells were shallow wells (10m), which could be easily affected
by sewage water, garbage, and agricultural non-point pollution. For villagers who chose well
water, some reflected that during the wet season the quality and colour of the well water would
change. This could be connected with well locations (those near polluted waters would be bad)
and geological conditions. The surveyed Region was of Karst landform, with high silt content
and heavy surface water leakage, thus remarkably impacting the well water via leakage of
surface pollutants. Therefore, emphasis on management of forestry, agriculture, and community
environment was essential for the safety of drinking water for the majority of local villagers.
Figure 4-44 Household Drinking Water Sources in the Nanning Region
4.2.1.2 Yulin Region
Among the surveyed villagers, those who used tap water, well water, and mountain spring
water accounted for 15.83%, 51.32% and 17.03% respectively. Those who used water from
rivers and streams reached 13.67%, while those who used water from the reservoirs were
40
relatively few, only 2.16% (Figure 4-45). Those who used shallow well water (10 m) accounted
for 73.95%, suggesting that the level of local water pollution was not very serious. Most lands in
this Region belonged to quaternary red soil, of which the structure was hard-packed and surface
leakage not so heavy. According to the surveyed villagers, due to reservoir breeding, for many
years the water pollution had been too serious for the water to be drunk directly.
Figure 4-45 Household Drinking Water Sources in the Yulin Region
4.2.1.3 Beihai Region
The main drinking water source for the villagers in the Beihai Region was well water, of
which the proportion reached 60.12% (Figure 4-46). A few villagers used tap water and water
from rivers and streams. Well water was susceptible to environmental pollution; therefore
63.82% of wells were deep ones (10m), showing that most villagers paid close attention to the
safety of their drinking water.
41
Figure 4-45 Household Drinking Water Sources in the Beihai Region
4.2.1.4 Qinlian Region
Approximately 70% of the villagers in the Qinlian Region drilled wells for water, but 90%
of wells that provided drinking water were shallow ones (Figure 4-47). The second major water
source was tap water, which accounted for 28.04%.
Figure 4-47 Drinking Water Sources in the Qinlian Region
4.2.1.5 Summary
There are five kinds of drinking water sources for community villagers: tap water, well
water, mountain springs, water from rivers and streams, and water from the reservoirs. Among
42
those the proportion of well water was notably high in all four surveyed Regions. In general,
except in the Beihai Region, most of the wells were shallow, accounting for 73.09% (Figure
4-48). Water from shallow wells and mountain springs was vulnerable to environmental
pollution, such as fertilizers and pesticides in the farmland planting and plantation management.
Therefore, emphasis on management of forestry, agriculture, and community environment was
essential for the safety of drinking water for the majority of local villagers.
Figure 4-48 Overall Drinking Water Sources in the Surveyed Regions
4.2.2 Quality of Drinking Water
4.2.2.1 Nanning Region
As for the treatment processes of drinking water, only 29.82% was processed, mainly by
filtration and natural sedimentation. This merely eliminates the impurities in the water but does
not do much for bacteria and soluble pollutants. The drinking water of the other 61.40% villagers
was not treated, and the rest 8.78% said they had no idea whether it was treated or not (Figure
4-49).
43
Figure 4-49 Drinking Water Treatment Situations and Methods in the Nanning Region
59.65% of the villagers did not know if the quality of their drinking water complied with the
national standards. Even for those who said the water quality conformed to the standards, it was
largely out of speculation, accounting for 74.07% of the surveyed population. Merely 18.52% of
the domestic drinking water was supervised and tested by professional testing institutes (Figure
4-50). It was thus natural to conclude that the quality of drinking water for local villagers was
alarming.
Figure 4-50 Situations and Judging Methods of Drinking Water Quality in the Nanning Region
44
The local villagers expressed that they based their judgment of water quality on simple
perception, considering water with good transparency and little impurities up to standards;
therefore 33.33% were satisfied with the water quality and 57.90% thought it was acceptable.
Based on the collected data, there was a relatively high level of satisfaction among villagers
regarding water quality (Figure 4-51). Out of the 8.77% who were unsatisfied, only a few chose
colour, smell, taste, suspended articles, microorganisms or heavy metal pollution as reasons for
dissatisfaction; 80.00% selected "others", indicating that they were concerned about the water
quality but were not sure whether it had reached the standards or whether it would exert
negatively on the human body.
Figure 4-51 Satisfaction Rate and Reasons for Dissatisfaction with Drinking Water Quality from
Villagers in the Nanning Region
4.2.2.2 Yulin Region
Regarding drinking water treatment in the Yulin Region, only 27.94% was processed. The
main processing method was natural precipitation, which only removes the impurities from the
water but is not able to clear out bacteria and soluble pollutants. The drinking water for 63.71%
of the villagers was untreated, and 8.36% said that they didn't know whether the water had been
treated or not (Figure 4-52).
45
Figure 4-52 Drinking Water Treatment Situations and Methods in the Yulin Region
63.97% of the villagers did not know whether the water quality met the national drinking
water standards. Even those who said the water quality was qualified were just making a guess,
accounting for 69.83% of the surveyed population. Only 15.93% of household drinking water
was monitored by professional testing institutions (Figure 4-53). It could be concluded that the
drinking water quality of the villagers was worrying.
Figure 4-53 Situations and Judging Methods of Drinking Water Quality in the Yulin Region
According to the villagers, their evaluations of water quality were heavily dependent on
46
sensory feelings, thinking that good transparency and less impurities accounted for qualified
water qualities. 36.55% of the villagers felt satisfied with the water quality, 43.86% thought of it
as acceptable, and 19.58% said they were not satisfied (Figure 4-54). It could not be said that the
villagers were quite satisfied with the water quality, for local water conditions were also relevant.
This also suggested that the villagers were worried about the water quality, but not sure if the
water quality was good or harmful to the human body.
Figure 4-54 Satisfaction Rate and Reasons for Dissatisfaction with Drinking Water Quality from
Villagers in the Yulin Region
4.2.2.3 Beihai Region
Regarding drinking water treatment in the Beihai Region, 35.87% had been processed. The
main processing methods were filtration, natural precipitation, as well as treatment in water
plants. 54.41% of the villagers drinking water was untreated, and 9.73% of the villagers didn't
know whether the water had been processed or not (Figure 4-55).
47
Figure 4-55 Drinking Water Treatment Situations and Methods in the Beihai Region
57.45% of the villagers did not know if the water quality met the national drinking water
standards. Even those who said the water quality was qualified were just making a guess,
accounting for 78.85% of the surveyed population. Only 15.05% of household drinking water
was monitored by professional testing institutions (Figure 4-56).
As for evaluation of water quality, 31.61% of the villagers felt satisfied with the water
quality, 36.78% thought of it as acceptable, suggesting that the villagers satisfaction with water
quality was at an average level (Figure 4-56). Among the 31.61% of the villagers who were not
satisfied, 23.08% chose colour, 20.00% chose smell, 22.05% chose taste, 18.46% chose
suspended solids, 8.72% chose microorganism, and 6.15% chose the "other" option for the
reason of their dissatisfaction, indicating that the local water quality was affected by numerous
aspects.

Villagers
4.2.2.4 Qinlian Region
56.88% of the villagers in the Qinlian Region thought that their drinking water was
untreated, only 26.25% of the villagers thought it was treated, and 16.88% didn't know whether
their drinking water had been treated or not, and nearly 90% of the villagers thought that only
simple natural precipitation was applied (Figure 4-58). As many as 88.75% of the villagers didn't
know whether their drinking water met the national drinking water standards or not. Among
49
villagers who made a conclusion of conformity or unconformity, 98.56% just made a guess. Only
1.44% tested the water by themselves, and no villager trusted specialized institutions for testing
(Figure 4-59).
Figure 4-58 Drinking Water Treatment Situations and Methods in the Qinlian Region
Figure 4-59 Situations and Judging Methods of Drinking Water Quality in the Qinlian Region
About 75% of the villagers considered their drinking water satisfactory or acceptable, while
near 25% were not satisfied with the water quality. The main reason for dissatisfaction with
water quality derived from water colour, smell, taste and suspended solids (Figure 4-60).
50
Figure 4-60 Satisfaction Rate and Reasons for Dissatisfaction with Drinking Water Quality from
Villagers in the Qinlian Region
4.2.2.5 Summary
Most villagers were quite satisfied with the current quality of drinking water, but they
judged it by sensory feelings. 59.10% of drinking water was untreated; only 30.57% was treated;
and 10.33% of the villagers didnt know whether it was treated. The most commonly used
treatment method was natural precipitation, accouting for 55.27% (Figure 4-61).
Figure 4-61 Overall Drinking Water Treatment Situations and Methods in the Surveyed Regions
Only 10%20% of the villagers in the Yulin and Beihai Regions were sure that their
51
drinking water met the national standards. The proportion in the Nanning Region was slightly
higher, reaching 29.82%. Yet more than 50% of the villagers did not know whether their drinking
water met the national standards. Less than 20% of the villagers had their drinking water tested
by a professional organization, and about 80% evaluated the water quality based on mere
speculation (Figure 4-62).
Figure 4-62 Overall Situations and Judging Methods of Drinking Water Quality in the Surveyed Region
24% of the villagers were not satisfied with the drinking water quality, among whom 80%
thought there were problems in the water colour, taste, smell, and suspended solids. In the
Nanning Region, 8.77% of villagers were not satisfied with their drinking water quality, among
whom only 20% thought there were problems in the water smell, taste and suspended solids, and
80% thought problems existed in other aspects, excluding the colour, taste, smell, suspended
solids, microorganism and heavy metals (Figure 4-63).
52
Figure 4-63 Overall Satisfaction Rate and Reasons for Dissatisfaction with Drinking Water Quality from
Villagers in the Surveyed Regions
It can be seen from table 4-1 that among all respondents, 21.44% thought the drinking water
quality become worse in recent 10 years. The main reasons included eucalyptus plantation, water
pipe pollution, and untreated sewage. Among those who thought water quality got worse,
49.75% thought eucalyptus plantation was the main reason, implying that generally the villagers
held subjective views on eucalyptus plantations and water quality change.

4.2.3 Amount of Drinking Water
4.2.3.1 Nanning Region
The issues of the amount of water consumption and shortage of water resources varied
greatly from region to region. In general, the area with Karst landform had relatively limited
water resources and there was less water usage. Among the surveyed households, 54.39% used
53
less than 50 liters per capita per day and 19.30% used between 50 and 100 liters, the total of
which took up 73.69% of the families surveyed (Figure 4-64).
Figure 4-64 Daily Water Usage per capita of Villagers in the Nanning Region
Water shortage prevailed in the surveyed areas; the ratio of drinking water shortage was
close to 60% (Figure 4-65). As for water shortage time, the average water shortage period in the
surveyed households was five to six months a year, normally occuring from July to January,
while in other areas it usually occurred in the autumn and winter for a duration of three months.
Figure 4-65 Drinking Water Supply and Shortage in the Nanning Region
The vital problem in the surveyed regions was water resource shortages. The government
and village committees were planning to work on it, in such ways as assisting in the introduction
of tap water or drilling wells. 21.05% said the implementations would be conducted within three
54
years, while 42.11% said they would be conducted after three years, and a large percentage said
they did not have any plans due to lack of funds (36.84%).
4.2.3.2 Yulin Region
Among the surveyed villagers, 44.36% used less than 50 liters of water per capita per day,
44.47% used between 50 and 100 liters, the total of which took up 88.83% of the surveyed
families (Figure 4-66).
Water shortages prevailed in the investigated Regions, but not very serious at that, with
drinking water shortages taking up 27.23% (Figure4-67). 72.77% of the villagers held that their
drinking water was adequate. In addition, most of the villagers (up to 52.88%) maintained that
the water shortage lasted for 3 months.
Figure 4-66 Figure of Daily Water Usage per capita of Villagers in the Yulin Region
55
Figure 4-67 Drinking Water Supply and Shortage in the Yulin Region
The government or village committees had certain plans for water quality improvement
(such as drilling wells or introduction of tap water). 20.28% said the implementations would be
conducted within three years, 3.50% said they would be conducted after three years,, and 76.22%
said they did not have any implementation plans. Thus it can be viewed that the government had
not paid enough attention to the water usage safety of villagers, nor had it actually carried out its
plans.
4.2.3.3 Beihia Region
The amount of available water for the villagers in the Beihai Region could not be deemed
sufficient. Among the surveyed villagers, 35.56% used less than 50 liters per capita a day,
43.16 % used between 50 and 100 liters, the total of which took up 78.72% of the families
surveyed (Figure 4-68).
56
Figure 4-68 Figure of Daily Water Usage per capita of Villagers in the Beihai Region
Water shortages in the surveyed Regions were not too severe; the proportion of drinking
water shortage accounted for 31.61%, and villagers water usage quantities were quite similar,
without sharp shortages (Figure 4-69). As for the degree of water insufficiency, the places that
suffered from the issue mostly were Liwu Village, Huapu Village, Fucheng Town, Hepu County
and Beihai City, with an average annual water shortage period of more than 7 months, generally
occurring from July to January. In other Regions the shortage usually occurs in the autumn and
winter for a duration of three months, although there were also lot of villagers suffering from
water shortages that lasted 5-6 months.
Figure 4-69 Drinking Water Supply and Shortage in the Beihai Region
Regarding improvements in water usage, 11.46% of the surveyed said the implementations
57
would be conducted within three years, 22.92% said they would be conducted after three years,
and 65.63% said they did not have any implementation plans. Thus it cab be seen that the
government needs to pay more attention to the water usage safety of the villagers.
4.2.3.4 Qinlian Region
The daily water usage per capita of 98.21% of villagers in the Qinlian Region was less than
150L, lower than that of other three Regions (Figure 4-70).
Figure 4-70 Figure of Daily Water Usage per capita of Villagers in the Qinlian Region
55.35% of the villagers thought they had enough drinking water, a proportion lower than
that in the Yulin and Beihai Regions, but higher than that in the Nanning Region. Among those
who thought they lacked water, 67.61% said that the shortage period lasted for 3 months (Figure
4-71), the highest proportion among the four Regions, suggesting that the shortage period in this
Region was comparatively short and the water supply was relatively balanced.
58
Figure 4-71 Drinking Water Supply and Shortage in the Qinlian Region
4.2.3.5 Summary
In the four Regions covered by this survey, about 80% of the villagers used less than 100L
of water per capita every day (Figure 4-72).
Figure 4-72 Overall Daily Water Usage per capita in the Surveyed Regions
66.24% of the surveyed villagers thought that their water supplies were adequate, while one
third of the villagers thought they faced a water shortage. The length of the period per year when
water was insufficient could be up to 6 months, in most cases 3 months (Figure 4-73). However,
due to reasons such as lack of money and concepts, the villagers were not very enthusiastic about
improving water usage. Especially in the Yulin and Beihai Regions more than two thirds of the
villagers did not implement any plan for improving water usage.

It can be seen from table 4-1 that among all respondents, 24.35% thought the drinking water
quantity decreased in recent 10 years. The main reasons included eucalyptus plantation,
population increase, and climate change. Among those who thought water quantity decreased,
52.65% thought eucalyptus plantation was the main reason, implying that generally the villagers
held subjective views on eucalyptus plantations and water quantity change.

4.3 Agricultural Water
4.3.1 Sources of Agricultural Water
4.3.1.1 Nanning Region
Regarding agricultural water, the main surveyed content included livestock drinking water,
quantity and quality of agricultural water, irrigation facilities and levels of satisfaction. Because
60
most villagers in the surveyed Region raised poultry only for their own use via outdoor grazing,
the survey on livestock water sources was pretty random in results, between 16.92% and 24.62%,
divided between tap water, well water, mountain spring, rivers and streams, and reservoir.
Agricultural irrigation water was largely from rivers and streams, mountain springs and
reservoirs, accounting for 71.93%, 15.79% and 12.28% respectively (Figure 4-74).
Figure 4-74 Sources of Livestock Water and Agricultural Irrigation Water in the Nanning Region
4.3.1.2 Yulin Region
The proportions of water for livestock from tap water, well water, mountain springs, rivers
and streams, and reservoirs differed significantly, with rivers and streams reaching up to 43%.
Agricultural irrigation water was mainly from rivers and streams, mountain springs and
reservoirs, accounting for 46.32%, 24.63% and 24.21% respectively (Figure 4-75).
61
Figure 4-75 Sources of Livestock Water and Agricultural Irrigation Water in the Yulin Region
4.3.1.3 Beihai Region
Because villagers in the surveyed Region could live on agriculture, forestry, and animal
husbandry, sources for agricultural water differed greatly. Water from wells, rivers and streams
accounted for the most (60%); tap water, mountain spring,s and reservoir waters were between
3.32% and 27.62%. Agricultural irrigation water was mainly from rivers and streams, mountain
springs and reservoirs, accounting for 41.69%, 13.30% and 27.62% respectively (Figure 4-76).
Figure 4-76 Sources of Livestock Water and Agricultural Irrigation Water in the Beihai Region
4.3.1.4 Qinlian Region
53.27% of livestock water in the Qinlian Region was from wells the highest proportion in
62
the four areas. For agricultural irrigation, the situation was similar to that in the other three areas,
with water from rivers and streams taking the largest proportion, albeit with a small percentage.
Rainwater irrigation in this Region accounted for 31.40%, suggesting that rainfall in the area was
abundant (Figure 4-77).
Figure 4-77 Sources of Livestock Water and Agricultural Irrigation Water in the Qinlian Region
4.3.1.5 Summary
Agricultural water mainly came from tap water, well water, mountain springs, rivers and
streams, as well as reservoirs. Statistics show that irrigation water in the four Regions mainly
came from rivers and streams, followed by reservoirs, indicating that natural waters contributed a
lot to the development of agriculture. Rivers and streams was also a main source for livestock
drinking water (Figure 4-78).
63
Figure 4-78 Overall Sources of Livestock Water and Agricultural Irrigation Water in the Surveyed
Regions
4.3.2 Agricultural Irrigation Method and Level
4.3.2.1 Nanning Region
In the Nanning Region, irrigation was mainly arranged via ditches in the field (78.95%),
consuming large amounts of water. A great part of the water lost due to underground leakage and
surface evaporation. 17.54% of the irrigation water was via pipe irrigation (a method that saves
water), and 3.51% had arranged their irrigation via water carried by buckets (Figure 4-79).
Hence, irrigation methods wasted water, and may be one of the causes for water shortages.
Artificial irrigation for farmland was not popular, 46.43% of fields were without artificial
irrigation, and for 23.21%, the irrigation area was below 50%, suggesting from another aspect
that water resources in the surveyed Region were insufficient.
Figure 4-79 Farmland Irrigation Methods and Proportion in the Nanning Region
4.3.2.2 Yulin Region
Farmland irrigation methods in the Yulin Region were mainly via ditches (92.15%), pipe
irrigation (7.34%), and manual labor (0.51%) (Figure 4-80). Artificial irrigation for farmland was
popular (for 46.48% of the fields the irrigation area was over 90%), suggesting from another
aspect that water resources in the surveyed Region were abundant.
64
Figure 4-80 Farmland Irrigation Methods and Proportion in the Yulin Region
4.3.2.3 Beihai Region
There were three main methods for farmland irrigation in the Beihai Region, among which
ditch irrigation took the lead (90.24%). 7.93% was by manual labor, and 1.83% of the villagers
applied pipe irrigation (Figure 4-81). Artificial irrigation for farmland was not popular: for
12.73% of the farmlands the irrigation area was below 30%, suggesting that water sources for
farmland in the surveyed Region were insufficient.
Figure 4-81 Farmland Irrigation Methods and Proportion in the Beihai Region
4.3.2.4 Qinlian
65
In the Qinlian Region, ditch irrigation took up 55.83% (the lowest among the four Regions).
The proportion of rain irrigation was 21.47%, the highest among the four Regions, signifying
abundant rainfall in the Region, also proven by the fact that 48.67% of the farmland had an
irrigation proportion less than 30% (Figure 4-82).
Figure 4-82 Farmland Irrigation Methods and Proportion in the Qinlian Region
4.3.2.5 Summary
The main irrigation methods in the four surveyed Regions were ditches, pipe and manual
labor. Irrigation was mainly arranged via manmade ditches in the farmlands, reaching a
proportion 87.67% (Figure 4-83). The general proportion of fields which needed irrigation was
nearly 75%, while that in Yulin Region was over 90%. The proportions in the Beihai and
Nanning Regions dropped slightly for two reasons: (1) rich rainfalls in the Beihai Region and (2)
most of the land in the Nanning Region was dry farmland.

4.3.3 Quality and Quantity of Agricultural Irrigation Water
4.3.3.1 Nanning Region
When comparing the villagers satisfaction with agricultural water, 85.96% of the surveyed
households said it was satisfactory or acceptable. Among those who said they were not satisfied,
62.5%, 25% and 12.5% respectively chose the options of "other", "suspended solids" and "smell",
implying their uncertainty and concerns about the water quality (Figure 4-84).
Figure 4-84 Satisfaction Rate and Reasons for Dissatisfaction with Agricultural Water Quality from
Villagers in the Nanning Region
67
Water shortage is a global problem. 77.19% of the villagers reflected water shortages in
agriculture (Figure 4-85). The water shortage period varied between different Regions, usually
taking 3 to 8 months, mostly 6 months.
Figure 4-85 Agricultural Water Supply and Shortage in the Nanning Region
The proportion of forest land area owned by villagers in the surveyed Region was small.
Hence, the agricultural and forest irrigation proportions diverged greatly; those who used 100%
of the water for agricultural irrigation accounted for 79.25%. It was found via the survey that the
villagers did not attach much importance to the improvement of agricultural irrigation facilities:
only 10.53% planned to implement improvements within three years, 42.11% planned to
implement them three years later, while 47.37% did not plan to do anything. The reasons behind
this may be that the villagers' concepts of protecting and utilizating water resources are not
strong, the government support is not sufficient, funds remain insufficient, etc.
4.3.3.2 Yulin Region
In the Yulin Region, villagers satisfaction level with agricultural water was high. Those said
it was acceptable accounted for about 53.79% of the surveyed households, while those who said
they were not satisfied accounted for only for a third of the amount of satisfied households
(Figure 4-86).
68
Figure 4-86 Satisfaction Rate and Reasons for Dissatisfaction with Agricultural Water Quality from
Villagers in the Yulin Region
51.44% of the villagers reflected water shortages in agriculture (Figure 4-87). The water
shortage time varied between different Regions, from 3 to 6 months. For most the period was 3
months, accounting for 42.13%.
Figure 4-87 Agricultural Water Supply and Shortage in the Yulin Region
It was found via the survey that the villagers did not attach much importance to the
improvement of agricultural irrigation facilities; only 12.59% planned to implement
improvements within three years, 2.10% planned to implement three years later, while 85.31%
did not plan to do anything. The reasons behind this may be that the villagers' concepts of
69
protecting and utilizating water resources are not strong, the government support is not sufficient,
funds remain insufficient, etc.
4.3.3.3 Beihai Region
When comparing the villagers satisfaction with agricultural water, 21.04% of the surveyed
households said it was satisfactory, while 54.27% said it was acceptable. Among those who said
they were not satisfied, 23.88%, 20.15% and 13.43% respectively chose the reasons of "color",
"smell" and "taste" (Figure 4-88).
Figure 4-88 Satisfaction Rate and Reasons for Dissatisfaction with Agricultural Water Quality from
Villagers in the Beihai Region
55.21% of the villagers reflected water shortages in agriculture (Figure 4-89). The water
shortage time varied between different Regions,from 3 to 8 months, the most common period
being 3 months. It is worth noting that in Liwu Village, Huapu Village, Fucheng Town, Hepu
County and Beihai City, the average annual water shortage time was over 7 months. Many
villagers lacked water for 5-6 months, others for 3-4 months
70
Figure 4-89 Agricultural Water Supply and Shortage in the Beihai Region
4.3.3.4 Qinlian Region
70% of the villagers in this Region thought the agricultural water acceptable. The numbers
for villagers who said they were satisfied and for those who were not satisfied were quite similar.
The reasons for dissatisfaction were mainly color, smell, taste and suspended solids. Compared
with the other three Regions, the reasons for dissatisfaction were clearer (Figure 4-90). 57.50%
of the villagers reported agricultural water shortages, and most said the shortage period was 3
months (Figure 4-91).

4.3.3.5 Summary
Taking all the surveyed Regions into consideration, 17.56% of the respondents were not
satisfied with their agricultural water quality (Figure 4-92). The proportion in the Yulin Region
was the lowest, 11.75%, and the proportion in the Beihai Region was the highest, 24.7%. The
proportion differed greatly between the four Regions. The overall proportion of dissatisfaction
was lower than that of drinking water; the unsatisfactory aspects were mainly color, smell and
suspended solids.
72
Figure 4-92 Overall Satisfaction Rate with Agricultural Water Quality in the Surveyed Regions
50% of the villagers in the Beihai and Yulin Regions reflected agricultural water shortages,
the proportion in the Nanning Region increasing up to 77.19%. The overall percentage of
agricultural water shortages in the surveyed Regions reached 57.05% (Figure 4-93). As for the
length of water shortages per year, about 30% of the villagers in the Yulin Region thought the
period was 6 months, Over half of the villagers in the Beihai Region thought the period was less
than 3 months, and in the Nanning Region about 60% of the villagers thought it lasted six
months or longer, showing that Regionagricultural water was seriously insufficient in the
Region.

4.4 Domestic Sewage
4.4.1 Treatment and Discharge Methods of Domestic Water
4.4.1.1 Nanning Region
As the living standards of the villagers have risen, their requirements for the family
environment has gradually increased. The proportion of flush toilets in the Nanning Region was
large, accounting for 85.25%. The proportion of three-section septic tanks was 49.25%, that of
biogas fermentation was 14.93%, and that of other methods or no treatment were 13.43% and
22.39%, respectively. This part may go into the farmland, fish ponds and seep into the
underground through natural ground flowing and open channels. As for the discharge method,
73
53.85% was emitted through pipeline, 36.92% and 9.23% by natural flow and open channels
respectively (Figure 4-94).
Figure 4-94 Treatment and Discharge Way of Villagers Domestic Sewage in Nanning Region
4.4.1.2 Yulin Region
68.67% of the villagers in the Yulin Region used three-section septic tanks, 6.01% used
biogas fermentation, 4.7% used other methods and 20.63% did not treat the water. As for
discharge of domestic sewage, 3.69% was emitted through pipes, 50.13% by open channels, and
46.17% through natural flow (Figure 4-95). Pipeline discharge, affecting the environment least,
was of the lowest proportion.
Figure 4-95 Treatment and Discharge Way of Villagers Domestic Sewage in the Yulin Region
4.4.1.3 Beihai Region
As for sewage treatment methods, the proportion of three-section septic tanks was 58.82%,
biogas fermentation 6.76%, and other methods or no treatment were 5% and 29.41% respectively.
74
This part may go into the farmland, fish ponds and seep into the underground through natural
ground flowing and open channels. As for the discharge method, 9.06% was emitted through
pipelines, 44.71% and 46.22% by natural flow and open channels respectively, thus inevitably
resulting in huge amounts of waste and pollution (Figure 4-96).
Figure 4-96 Treatment and Discharge Way of Villagers Domestic Sewage in the Beihai Region
4.4.1.4 Qinlian Region
The proportions of three-section septic tanks, biogas fermentation, other methods or no
treatment accounted for 55.06%, 12.03%, 7.59% and 25.32% respectively. The main methods of
sewage discharge were through open channels and natural flowing. The proportion of pipeline
discharge was very low (Figure 4-97).
75
Figure 4-97 Treatment and Discharge Way of Villagers Domestic Sewage in the Qinlian Region
4.4.1.5 Summary
The main sewage treatment methods in the surveyed Regions were three-section septic
tanks and biogas fermentation, reaching 69.41%, yet the proportion of direct discharge without
treatment also accounted for nearly a quarter (24.68%) (Figure 4-98). Main emission methods
were open channel discharge and natural flow, with pipe emissions accounting for an extremely
low proportion. The main discharge methods in the Yulin and Beihai Regions were natural flow
and open channel discharge. In the Nanning Region the main discharge methods were pipe
emissions and natural flow, with the latter being applied more often.

Regions
4.4.2 Discharge Destination of Domestic Water
4.4.2.1 Nanning Region
Most of the villagers' sewage was discharged into fish ponds, farmland and rivers and
seeped into the ground, accounting for 33.33%, 12.28%, 8.77% and 45.61% respectively of the
total discharge (Figure 4-99), thus causing serious pollution to surface water.
Figure 4-99 Domestic Sewage Discharge Destinations in the Nanning Region
Regarding drinking water sources and wastewater discharge destinations, the proportion of
them not being in the same water body was 85.96%. However, 14.04% are of these are still in the
same water body. Most of the surveyed villagers thought the rivers were lightly polluted,
accounting for 78.95%, and those who thought the pollution was at a medium level or severe
level accounted for 10.53% and 1.75% respectively. Only 8.77% believed the rivers to be clean.
It could be drawn that most surface water in the surveyed Regions suffered from various degrees
of pollution.
The desire of the villagers to improve sewage treatment methods was not strong: only
17.54% planned to improve the situation within three years (generally this group was in better
living conditions) and 45.61% planned to improve after 3 years. 36.84% had no plans, which
may be a result of poor economic conditions or waiting for the government to take up
people-benefiting measures.
4.4.2.2 Yulin Region
77
Most of the villagers' sewage in the surveyed Region was discharged into fish ponds,
farmlands, rivers and seeped into the ground, accounting for 6.85%, 20.05%, 30.46% and
31.98% respectively. The amount of rural sewage facilities was 0 (Figure 4-100).
Regarding drinking water sources and wastewater discharge destinations, the proportion of
them not being in the same water body was 95.80%, with only 4.20% being in the same water
body. Most of the surveyed villagers thought the rivers were lightly polluted, accounting for
69.23%, and those who thought the pollution was at a medium level or severe level accounted
for 12.59% and 11.19% respectively. Only 7.0% believed the rivers to be clean. It could be
drawn that most surface water in the surveyed Regions suffered from various degrees of
pollution.
The desire to improve sewage treatment way was not strong: only 15.38% planned to
improve the situation within three years, 10.49% planned to improve after 3 years, and 74.13%
had no plans.
Figure 4-100 Domestic Sewage Discharge Destinations in the Yulin Region
4.4.2.3 Beihai Region
Most of the villagers' sewage in the surveyed Region was discharged into fish ponds,
farmlands, rivers and seeped into the ground, accounting for 11.27%, 23.74%, 13.19% and
43.65% respectively (Figure 4-101).
78
Figure 4-101 Domestic Sewage Discharge Destinations in Beihai Region
4.4.2.4 Qinlian Region
The main destinations of sewage were rivers, fields, and penetratation into the underground,
reaching over 95% of the total (Figure 4-102).
Figure 4-102 Domestic Sewage Discharge Destinations in Qinlian Region
4.4.2.5 Summary
The main destinations of sewage discharge were underground (41.24%), farmland (21.68%),
and rivers (19.84%), while the proportion of concentrated wastewater discharge (municipal water
pipes and rural sewage facilities) was very low, only about 2% (Figure 4-103).
79
Figure 4-103 Overall Domestic Sewage Discharge Destinations in the Surveyed Regions
For more than 80% of the villagers, drinking water sources and wastewater discharge
destinations were not in the same place. It could be deemed that the villagers disposed sewage as
they felt convenient and did not consider the environmental impact too much, which would
inevitably lead to the sewage seeping into the underground and polluting the groundwater. More
than half of the villagers believed the rivers were lightly polluted, with the main pollution
sources being from domestic sewage and garbage, chemical fertilizers and livestock breeding.
4.5 Relevant Opinions and Suggestions
4.5.1 Level of Satisfaction in Current Living Conditions
4.5.1.1 Nanning Region
Regarding living conditions, 66.67% villagers are content with their current living
conditions. Those who are unsatisfied blame low income, environment, and transport, taking up
52.38%, 28.57%, and 14.29% respectively. Another 4.76% believe that insect pests have caused
a negative impact on their lives. (Figure 4-104)
80
Figure 4-104 Level of Satisfaction on Current Living Conditions by Villagers in Nanning
4.5.1.2 Yulin Region
According to the survey, 66.06% villagers are satisfied with their living conditions. Of those
who are not happy with them, 44.54% think that their income level is relatively low, 46.22%
blame environmental issues, and 9.24% blame water shortages (Figure 4-105).
Figure 4-105 Level of Satisfaction on Current Living Conditions by Villagers in Yulin
4.5.1.3 Beihai Region
In Beihai, 55.32% of local villagers are pleased with their living conditions. The remaining
people mainly have problems in the following aspects: 56.16% think the environment conditions
81
are relatively poor, followed by income, which takes up 41.72%. In addition, the concerns
include water shortages, drinking conditions, personal problems, transport, and housing (Figure
4-106).
Figure 4-106 Level of Satisfaction on Current Living Conditions by Villagers in Beihai
4.5.1.4 Qinlian Region
In this area, 56.25% of the rural villagers are satisfied with their current living conditions.
The rest of the villagers are mostly dissatisfied with the environment, representing 53.95%; the
next most common reason is low financial income, accounting for 31.58%; other factors include
water shortage and absence of tap water (Figure 4-107).
Figure 4-107 Level of Satisfaction on Current Living Conditions by Villagers in Qinlian
4.5.1.5 Summary
82
Based on the level of satisfaction of the villagers who reside in the surveyed areas, the
overall satisfaction rate is 60.6% and the dissatisfaction rate is 39.4% (Figure 4-108). The main
reasons for dissatisfaction are environmental problems and income issues. In Nanning and Yulin,
the number of villagers who feel displeased with their living conditions account for around one
third of the population. In Nanning, most of them are unhappy with their income. On the other
hand, in Beihai and Qinlian, the dissatisfaction rate is relatively high, reaching 44%. Most of the
local citizens in Yulin, Beihai, and Qinlian cite environmental issues as the primary reason for
their dissatisfaction, while income is the second biggest reason.

Areas
4.5.2 Willingness to Improve the Environment
4.5.2.1 Nanning Region
When looking at improvement projects that villagers are hoping to be implement, aside
from centralized sewage treatment (21.26%), the percentages of desires for other projects are
evenly distributed. Ranging from governance of water body pollution, centralized treatment of
garbage, transport and improvement of housing to improvement of drinking water, the
percentages are all between 14.17 and 18.11 (Figure 3-103).
83
Figure 4-109 Willingness to Improve the Environment by villagers in Nanning
Notes: From Figure 4-109 to Figure 4-113, water treatment means polluted water body treatment,
improve drinking water means improve drinking water quality.
4.5.2.2 Yulin Region
Of all improvement projects, the people in Yulin prefer to see the following changes:
improvement of sewage treatment (19.30%), garbage treatment (16.73%), improvement of
drinking water (16.73%), and improvement of transport (17.54%). Other changes they would
like to see happening include governance of water body pollution, improvement of village
surroundings, and improvement of housing conditions (Figure 4-110).
Figure 4-110 Willingness to Improve the Environment by villagers in Yulin
84
4.5.2.3 Beihai Region
Of all improvement projects they hope to see implemented, the lowest percentage accounts
for the improvement of housing (7.11%). Sewage treatment, improvement of drinking water, and
improvement of village surroundings enjoy wide support, taking up 21.49%, 18.09%, and
16.88% respectively (Figure 4-111).
Figure 4-111 Willingness to Improve the Environment by villagers in Beihai
4.5.2.4 Qinlian Region
Of all the improvement projects, the villagers in Qinlian would like to see improvement of
drinking water conditions the most, accounting for 22%. Improvement of villages surrounding
environment accounts for 18.52%, ranking the second highest. Except for willingness to improve
transport, which they think is the least important and only accounts for 5.66%, they still hope to
see improvements in sewage treatment, water body governance, garbage disposal, housing
conditions and so forth, the proportion of each varying between 10% and 15% (Figure 4-112).
85
Figure 4-112 Willingness to Improve the Environment by villagers in Qinlian
4.5.2.5 Summary
According to surveys in the researched areas, villagers primary hopes for improvement in
terms of environmental issues are mainly focused on centralized sewage treatment, governance
of water body pollution, centralized treatment of garbage, and improvement of drinking water
conditions. Of these the most pressing needs are for sewage treatment and improvement of
drinking water quality, accounting for 19.06% and 18.19% respectively. The people also hope to
see changes in garbage disposal, the surrounding environment, and governance of water body
pollution, percentages ranging between 13% and 15%. In addition, the people hope that the
transport and housing conditions could also be improved (Figure 4-113).

4.5.3 Reasons for Restricting the Development of Villages
4.5.3.1 Nanning Region
Regarding reasons for restricting development, local villagers list 12 reasons (Figure 4.114).
The most prominent problems include weak economic foundation, poor road conditions,
insufficient water sources and lack of transport conditions, representing 20.75%, 18.87%,
15.09% and 11.32% respectively. The overall concern over pollution also reached 11.32%,
although in rather diverse aspects, including massive polluted spots, water body pollution,
garbage disposal, air pollution, etc.
Figure 4-114 Reasons for Restricting the Development of Village in Nanning
4.5.3.2 Yulin Region
Most villagers trace the factors that limit the development of their village to inconvenient
transportation, insufficient funding, lack of government support and unavailability of technology,
accounting for 26.96%, 25.90%, 10.69% and 12.05% respectively (Figure 4-115). The peoples'
concern over pollution also reaches 6.63%. Other reasons are also involved, such as water
shortage, lagging notion, insufficient labour, and land infertility.
87
Figure 4-115 Reasons for Restricting the Development of Village in Yulin
4.5.3.3 Beihai Region
Most villagers blame insufficient funding, environmental pollution, and weak government
support for restricting village development, accounting for 19.44%, 19.13%, and 13.37%
respectively. Lack of technology, inconvenient transportation, and lagging notion each take up
approximately 10%. Lack of labour (6.69%), infertile land (5.29%), and water shortages (4.67%)
are also factors mentioned (Figure 4-116).
88
Figure 4-116 Reasons for Restricting the Development of Village in Beihai
4.5.3.4 Qinlian Region
Regarding elements that undermine village development, most people believe the most
common are lack of funding, insufficient government support and absence of technology,
altogether making up 50%. Shortage of labour and environmental pollution are among other
important factors (Figure 4-117).
Figure 4-117 Reasons for Restricting the Development of Village in Qinlian
4.5.3.5 Summary
Across all investigated areas, 20.84% villagers assert that the lack of village development is
caused by insufficient funding. 15.32% think the reason is inconvenient transport, and 13.20%
believe the government does not grant enough support. Other factors, including lack of technical
support, environmental pollution and lagging notion account for 12.81%, 12.31%, 6.63%
respectively, whereas water shortages, shortage of labour and infertile land represent 18.89%
altogether (Figure 4-118).

4.5.4 Willingness to Fund Projects that Improve Drinking Conditions and
Sewage Treatment
4.5.4.1 Nanning Region
When asked how much they would be willing to contribute to the funding of projects on
improvement of drinking water conditions and sewage treatment (initiated by the government),
villagers basically are willing to pay less than 50% (Figure 4-119). The main reason is that they
have no idea what kinds of amounts are needed for the projects, and therefore they are unable to
provide an answer based on their financial capacity.
90
Figure 4-119 Villagers Willingness to Fund Projects that Improve Drinking Conditions and Sewage Treatment
in Nanning
4.5.4.2 Yulin Region
As for projects launched by the government that would improve drinking water conditions
and sewage treatment problems, the majority of local people are willing to pay less than 500
yuan (Figure 4-120). The seemingly small amount of funds they are willing to commit is a result
of their poor living conditions.
Figure 4-120 Villagers Willingness to Fund Projects that Improve Drinking Conditions and Sewage Treatment
in Yulin
91
4.5.4.3 Beihai Region
As for funding projects launched by the government that would improve drinking water
conditions and sewage treatment problems, most local villagers are willing to pay less than 500
yuan (Figure 40-121); however, 10% of them would be pleased to offer between 500 and 1000
yuan, and a few of the people would even offer more than 1,000 yuan, This indicates that the
local people in this area have a certain level of awareness regarding improvements in drinking
water quality and sewage treatment.

Similar to the other three areas, villagers in Qinlian in general are only willing to contribute
less than 500 yuan to improve drinking water quality and sewage treatment. However, its worth
noting that the amount of funds they are willing to commit is between 100 yuan and 500 yuan,
higher than that in the other three areas (Figure 4-122).

4.5.4.5 Summary
As for contributing to projects launched by the government that would improve drinking
water conditions and sewage treatment problems, most villagers are ready to part with less than
500 yuan (Figure 4-123). As most rural families in the surveyed areas have very limited income,
they cannot afford large amounts of funding; thus, most people hope for government support.
Nevertheless, a few locals have a stronger desire to improve their drinking water conditions and
sewage treatment, and are therefore willing to contribute more money.

4.5.5 Utilization of Biogas Slurry and Biogas Residue
4.5.5.1 Nanning Region
As for utilization of biogas and its by-products, most villagers are willing to use biogas
slurry to irrigate farmland and use biogas residue as fertilizer, accounting for 78.95% and
84.21%. The remaining locals who are reluctant think that either the transport distance is too
long or collecting is not convenient (Figure 4-124 and Figure 4-125).

Figure 4-125 Villagers Points of View on Using Biogas Residue as Fertilizer in Nanning
4.5.5.2 Yulin Region
As for utilization of biogas and its by-products, most villagers in Yulin (86.40%) are willing
to use biogas slurry to irrigate farmland. The ones who are unwilling claim that slurry collection
94
is not convenient and causes too much trouble (44.23%), is too dirty (19.23%), is not effective
(13.46%) or transport distance is too long (11.54%). The other 11.5% think that the biogas tanks
are not good or the conditions are not favourable (Figure 4-126).
Figure 4-126 Villagers Points of View on Using Biogas Slurry to Irrigate Farmland in Yulin
Regarding utilization of biogas residue, 91.91% of the locals in Yulin indicate their
willingness to use it as fertilizer (Figure 4-127). Those who refuse to use it believe that the
collection and utilization processes are not convenient.
Figure 4-127 Villagers Points of View on Using Biogas Residue as Fertilizer in Yulin
4.5.5.3 Beihai Region
83.29% citizens in the surveyed area in Beihai are willing to utilize biogas,; the rest think
that the collection and utilization processes are not convenient, reaching 42.62%, followed by
95
infeasible conditions (26.23%), long transport distances (16.39%), and "poor effect" or "too
dirty" (15%) (Figure 4-128).
Figure 4-128 Villagers Points of View on Using Biogas Slurry to Irrigate Farmland in Beihai
Regarding utilization of biogas residue, 82.07% of the local villagers in Beihai express their
willingness to use it as fertilizer (Figure 4-129). Those who refuse to use it believe that the
collection and utilization processes are not convenient or the conditions are unfavourable,
accounting for 68.96% altogether. At the same time, 15.52% villagers did not like the idea
because they are not used to it, or for other reasons.

4.5.5.4 Qinlian Region
Most villagers in Qinlian are willing to use biogas slurry to irrigate farmland, representing
96
92.50%. The unwilling locals assert that the collection and utilization processes are not
convenient, constituting 54.55%; other reasons include long transport distances (27.27%) and
unfavourable conditions (18.18%) (Figure 4-130).
Figure 4-130 Villagers Points of View on Using Biogas Slurry to Irrigate Farmland in Qinlian
Regarding utilization of biogas residue, 93.75% of the local villagers in Qinlian are willing
to use it as fertilizer (Figure 4-131); those who decline to use it believe that the collection and
utilization processes are not convenient, reaching 60%. Another 30% of the villagers claim that
the transport distances are too long, and the remaining 10% state that biogas residue is too dirty
to be used as fertilizer.

4.5.5.5 Summary
Most villagers welcome utilization of biogas and are willing to use the residue fermented by
biogas. 85.09% of all villagers in the surveyed areas would be pleased to use biogas slurry for
irrigation purposes, particularly in Qinlian, where the proportion of population in favour of using
it reaches 92.5%. The proportion is relatively low in Nanning, accounting for less than 80%. The
small portion of villagers who are reluctant to utilize biogas and its residue cite reasons such as
inconvenient collection and utilization processes and long transport distances, altogether
representing over 60% of the reluctant ones. In addition, 15.44% think that the conditions are not
feasible, and another c. 20% claim that it is not effective or is too dirty (Figure 4-132).
Figure 4-132 Villagers Points of View on Using Biogas Slurry to Irrigate Farmland in all surveyed Areas
88.27% of all villagers in the surveyed areas are willing to use biogas residues as fertilizer;
especially in Qinlian and Yulin, where the proportion of population in favour of using it exceeds
90%. The small portions of villagers who are reluctant to use them think that the collection and
utilization processes are not convenient and transport distances are long, together representing
over 60% of the reluctant ones. 17.54% think the conditions are not feasible, and another 6.14%
believe that the result for using it would be poor. Other reasons include "not a good idea", "too
dirty", or "not accustomed to use it", representing less than 5% (Figure 4-133) of the villagers.

4.5.6 Others
Regarding plans to increase family income, villagers in the surveyed areas mostly choose to
work in other cities or increase the scale of breeding and plantations.
The villagers made several suggestions regarding improvement of living standards, such as
increase of subsidies and government support as well as improvement of transport. Some suggest
improvements for environmental conditions, such as improvement of drinking water conditions
and drainage conditions, resolving water shortages, and building sewage treatment facilities. Due
to the fact that there has been controversy over environmental problems caused during the
development of eucalyptus forest plantations, some local villagers brought up suggestions to ban
eucalyptus plantations.
99
5 Result of Surveys Targeting Government Authorities Regarding preservation of drinking water sources, the governments plans include: isolate
hills for forestry, reinforce publication and supervision, launch a clean the village campaign,
close enterprises that cannot meet the environmental standards, and organize centralized
treatment for garbage and sewage in areas where villagers live close by. Some local governments
also state that they plan to cut down eucalyptus within the distance of 500m from water sources
to ensure the purity of the sources.
Regarding water supply, local governments assert that problems regarding seasonal water
shortages, relatively poor water quality in some areas, unavailability of suitable water sources,
insufficient funding, and difficulty in laying pipelines still exist. Most villagers drink water from
their own wells (the depth usually being within 10 meters), which makes centralized
management unfeasible.
The treatment method for household sewage is via natural flow. Insufficient funds, sparse
living conditions of villagers and low awareness of pollution control make sewage difficult to be
collected and treated collectively.
Most local governments believe that the water quality under their jurisdiction is rather good,
and the main pollutants are primarily household sewage, animal excrement, pesticide residue,
and solid waste. The sampling of drinking water for testing purposes should include heavy
metals, microorganisms, and pH. The cost of treatment technologies for drinking water should be
relatively low, and the maintenance involves merely simple filtering and sterilizing.
In terms of sewage treatment, government authorities suggest to build biogas tanks, artificial
wetlands, and auxiliary sewage treatment plants. They believe that local villagers have a strong
desire for improving the conditions of water supply and drainage. Unfortunately, in rural areas,
there are many obstacles to conquer when it comes to implementation of water supplies and
sewage treatment projects; these obstacles include insufficient funding, difficulty in management,
low awareness, etc.
As for the enterprises responsibilities, the government authorities believe that self-constraint
is important. Everyone should set a good example by meeting the discharge standards.

6 Result of Surveys Targeting NGO NGOs that participated in the survey included: Beihai Citizen Volunteer Association, Bozhongren
Environment Protection Association of Beihai College of Beihang University, Greenovation Hub and Guangxi
Green Association.
Regarding issues on water environment, they thought that:
(1)The government should strengthen publicity to make the villagers understand the
importance of cherishing water and saving water, standardize pollution caused by cultivation and
crop farming, as well as guarantee the cleanliness of drinking water sources.
(2)The current problems in rural water supplies are seasonal water shortages,
non-compliance of water quality (agricultural non-point pollution and pollution caused by
small-size breeding), and the villagers lack of water protection consciousness.
(3)Random discharge of domestic sewage pollute the surface water and underground water
to a certain extent, yet at present there is no corresponding supervision mechanism.
(4)The monitoring items of the villagers drinking water quality should include: turbidity,
hardness, PH, dissolved oxygen, organic and toxic substances, bacteria, ammonia nitrogen, and
pesticide residues (investigate the pesticide types). Technologies that can be used for
improvement of drinking water quality are: supporting sewage treatment equipment, filtration
and sterilization equipment, flocculation - precipitation - filtration process (suitable for
promotion in the countryside).
(5)The villagers have a strong desire to improve their drinking water quality, but at present
face problems of insufficient funding and difficulty in equipment management and maintenance.
(6)The enterprises should take the lead and work with villagers to reduce pollution caused
by production and domestic life.

7 Conclusion
7.1 Basic Information In the four areas investigated, the age proportion of villagers between 20 and 60 exceeds
60%, representing the majority of the population. Villagers within that age range in Nanning
account for 72.06%, ranking highest among all four regions. The overall educational level of
villagers is relatively low, and only 20% of them have an educational background that is higher
than junior middle school. This directly affects behaviour and professional skills, as well as
family income.
The financial situations of these four areas are as follows: Nanning > Yulin > Beihai >
Qinlian. In principle, the income levels of local villagers are not high, and 90% of them have an
annual family income that is lower than 10,000 yuan. 90% of the income for rural families
comes from labour work in cities, and from plantation, breeding, and forestry industries.
Generally, most lands are used for forestry purposes, making up 64% and thus being
favourable for the development of forestry industry. In particular, Beihai has the largest
proportion of forest land area, and the eucalyptus plantation ratio is close to 100%. In Qinlian,
the ratio exceeds 95% as well.
Over 70% of villagers use less than 100 kg fertilizers per mu and less than 2.5 kg pesticides
per mu. This indicates that the production levels in the surveyed areas are low; on the other hand,
agricultural pollution plays a relatively limited role on the environment.
More than 60% of the local villagers consider their living conditions clean or relatively
clean, among which those who reside in Nanning have the highest satisfaction rate. In terms of
fuel, due to the increasing number of migrant rural workers and decreasing number of household
members, the amount of livestock kept by the families is limited, most of which is for own
consumption only. Therefore, without large amounts of excrement from livestock, it is rare for
families to use biogas in spite of the support from most families for using biogas, its slurry and
its residue. From an overall point of view, the environmental challenges faced by the villagers
are usually caused by random discharging of household sewage water, piling of garbage,
utilization of large amounts of fertilizers and pesticides, low educational level, and lack of
102
implementation of environmental protection measures.
7.2 Drinking Water
There are five different types of sources for drinking water: tap water, mountain spring
water, water from wells, water from rivers and streams, and water from reservoirs. Among them,
water from wells takes up highest portion, accounting for 57.09%. The next most common
source is tap water, representing 21.51%. In general, except for Beihai, most of the wells are
shallow wells, constituting 73.09%.
According to research on drinking water quality, the majority of villagers hold a relatively
satisfactory attitude towards the quality of their drinking water. Nevertheless, their judgement on
quality is based merely on impression; in fact, close to 60% of the drinking water is untreated.
The most commonly used treatment method is natural sedimentation. There are relatively high
proportions of sterilized drinking water in Yulin and Nanning, mainly because they use tap water
more regularly.
Over 50% of local villagers are unsure about whether their drinking water complies with the
national drinking water standards. 80% of them judge the water quality purely by assumption.
24% of the villagers are not pleased with their drinking water quality, and most of them
think the problems exist in its colour, odour, smell, and suspended particles.
80% of the villagers consume less than 100 litres of water daily. As for water supplies,
33.76% believe that shortages exist. The shortage duration can be up to six months; in most
places, it is three months. Due to reasons related to funding and mindset, the villagers are not
very interested in improving any water-related aspects.
In the surveyed four regions, there are 21.44% of villagers believe the water quality has
become worse. The reasons for worse water quality include pollution of water pipes, eucalyptus
plantations and untreated sewage. The percentage of respondence who believes eucalyptus
causing worse water quality is 49.75%. There are 24.35% of villagers believe the water quantity
has decreased. The reasons for the water quantity decreased are eucalyptus plantations,
population increase and weather. The percentage of responence who believes eucalyptus causing
water quantity decrease is 52.65%.
103
7.3 Water for Agricultural Use
Water for agricultural use in the surveyed areas comes mainly from tap water, well water,
mountain spring water, as well as from rivers, streams, and reservoirs. Of these, rivers and
streams are the most common sources, and water reservoirs is the second most common.
Methods for agricultural irrigation include water via trenches or pipes and water that is
carried manually. Artificial trenches account for 87.67%. In general, the agricultural land in the
surveyed area that requires irrigation accounts for almost 75% of the total land area.
The percentage of villagers that are unsatisfied of the quality of water for agricultural use is
17.56%. This proportion is the highest in Beihai, and the most common reasons for the
dissatisfaction are colour, odour, and suspended particles.
Shortages of water for agricultural use exist in various degrees in every surveyed area. The
shortage degree across all investigated areas reaches up to 57.05%. In most places, the duration
of shortages is less than six months, usually being three months (accounting for 46.46%).
7.4 Household Sewage
The most common treatment methods for household sewage are three-section septic tanks
or biogas fermentation, accounting for 69.41% in total. However, untreated sewage discharge
also accounts for 24.68%. The most common discharge methods for household sewage are via
open trenches or through natural flow, representing over 90%.
Most of the discharged sewage in the researched areas infiltrates into underground (41.24%),
into farmland (21.68%), and into rivers (19.84%). The proportion of centralized treatment and
discharge for sewage (with municipal underground pipes and rural area sewage facilities) is very
low, at only 2%. Nevertheless, over 80% of the sewage is discharged to a place that is different
from the sources of drinking water.
Over half of the people surveyed believe that the rivers in their area are slightly polluted.
The main sources of pollution include household sewage, garbage, fertilizers, pesticides, and
livestock breeding.
104
7.5 Relevant Views and Suggestions
Across all investigated areas, 39.4% of the villagers are unsatisfied with their current living
conditions, mainly regarding the environment and financial income.
Regarding environment, the villagers' greatest hopes lie in sewage treatment and the
improvement of drinking water, which account for 19.06% and 18.19% respectively; the people
also wish to see improvements in garbage disposal, the general surrounding environment, and
treatment of pollution in bodies of water.
The people think that lack of funding is the main reason restricting the development of
villages, in addition to inconvenient transportation, insufficient support from the government,
lack of technical support, and environmental pollution.
Regarding the governments intention to help improve the situation of drinking water and
sewage treatment, the average amount of financial contribution that the villagers are willing to
make is less than 500 yuan in most cases in the researched areas. This is mostly because the
family incomes among the households are relatively low, thus making sizeable financial
commitments unfeasible. Therefore, most people set their hopes on government support.
The majority of local villagers welcome the idea of using biogas. 85% of them are willing
to use residue from biogas fermentation, particularly the villagers in Qinlian. Those who are
reluctant to use biogas residue cite reasons such as "inconvenient collection" and "long distances
of transport".
In the investigated areas, villagers primary methods for increasing their income include
working in cities and increasing their scale of animal breeding. On the other hand, they also hope
to receive more subsidies, to obtain more support from the government, to improve transport
conditions, to improve the quality of drinking water and drainage, to solve water shortages, and
to build sewage treatment facilities.
7.6 Actions and Suggestions from Authorities Regarding the Water
Environment
Regarding the preservation of drinking water source,s the governments plans include: to
105
isolate hills for forestry, launch a clean the village campaign, and organize centralized treatment
for garbage and sewage.
The primary reasons for water shortages include seasonal drought, unavailable water
sources, insufficient funding, and difficulties in laying pipelines.
It is proposed to build biogas tanks, artificial wetlands, and auxiliary sewage treatment
plants; however, in reality, sewage collection and centralized treament is difficult to arrange
because funding is not sufficient and the villagers live too far apart.
Most local governments assert that the water quality under their jurisdictions is relatively
good. The sampling of drinking water for testing purposes should include heavy metals,
microorganisms and pH. The testing indicators of drinking water should include heavy metals,
microorganisms and pH. For drinking water treatment technology, its suggested to choose
filtering and sterilizing with relatively low cost and simple maintenance.
7.7NGOs' Suggestions for Regarding the Water Environment
Government should reinforce communications and regulate pollution sources (such as
breeding and plantation industries) in order to maintain the cleanness of drinking water sources.
Currently, the main reasons for water supply shortages include seasonal droughts,
unqualified water quality, and lack of awareness for water source preservation of villagers.
Local villagers have a strong desire to improve the quality of their drinking water, but the
problems at hand include lack of funding and difficulties in managing and maintaining the
required equipment.
7.8 Suggestions for Pilot Project
Taking into account comprehensive opinions and considerations from villagers, government
authorities and NGOs, the following suggestions are proposed for choosing and implementing a
pilot project:
(1) Currently, water-related issues exist prevalently in the rural areas of Guangxi. These
issues include the amount and quality of drinking water, sewage treatment, and water used for
irrigation purposes. Therefore it is suggested that the future pilot projects should cover all types
106
of water-related projects, including drinking water supply projects, sewage treatment projects,
irrigation projects, and so forth.
(2) Regarding drinking water and sewage issues, the relevant authorities have enacted a
series of planning documents, policies, and measures. The applicants who intend to apply for the
pilot project should be in contact and consult thoroughly with the relevant authorities to propel
the implementation of the project effectively, applying related policies.
(3) At present, people living in the villages lack knowledge and awareness regarding how
to use water safely and how to perserve water sources effectively. This does not contribute to the
improvement of the rural water environment. It is proposed that publications and training should
an important element in the pilot project.
