2.1 Need for the project

SIMIP is proposed to irrigate dry lands in villages of Savanur Taluk of Haveri district.

The villages coming under this scheme are drought affected and agriculture is the

only source of livelihood and income. The annual average rainfall is 484 mm which is

primarily during the monsoon season (June - September). uncertainty within a year

causes the agriculture a risky venture. Savanur Taluk of Haveri District are considered

to be the more backward taluk. The people of the region have no other

employment opportunities except agriculture. Hence providing irrigation and

stabilizing the agricultural production, provides a much needed relief to the people.

It improves the per capita income and standard of living of the people. Further it

utilizes the water and land resources and substantially improves GDP contribution

from agriculture.

Therefore, there is a need of the scheme which could benefit the drought affected

area and shall also improve the Irrigation potential and Socio-Economic conditions

of the Haveri District. In this regard, SIMIP is considered to be the feasible in terms of

causing least environmental impacts among various alternatives considered in the

past few decades.

2.2 Water availability

Central Water Commission (CWC) maintaining a gauging station at Marol on

Varada river located upstream of its confluence with Tungabhadra river. The

catchment area of river Varada at this point is 4902 Sq.km. About 35.15 TMC of

water is available at SIMIP site. Out of which, it is proposed to divert 1.5 TMC of water

between July-December to irrigate 15500 Ha of dry lands in Savanur Taluk, Haveri

District.

3. Description of baseline environment

Collecting the baseline environmental status of the project area helps to ascertain the

magnitude of impacts that are likely to be caused due to the proposed project on

different environmental components. It also helps to identify critical environmental

attributes required to be monitored during and after the proposed development. To

assess the baseline environmental status, command area, 10 Km radius from the main

project components were considered and the data was collected during the period

Summer Season (March to May, 2015), Monsoon Season (June to August 2015) and

Winter Season (September to November, 2015). In addition to the baseline

environmental monitoring, field inspection in the study area, collection of secondary

information for all the environmental components and discussions with the officials

and local public were conducted by the experts to establish realistic information on

the area w.r.t the project.

3.1 Physical Environment

3.1.1 Geography and Topography

The command area of the project covers Haveri district. Slope plays an important role

in land irrigability and land capability assessment. The area is flat and continuous

sloping without undulations towards the Varada river. The topography of the project

area is partly plain and partly sloping. The elevation in the study area ranges from RL

430.00 m to RL 540.00 m.

3.1.2 Climate & Meteorology

Air borne pollutants is dispersed by atmospheric motion. Knowledge of these motions,

which range in scale from turbulent diffusion to long-range transport by weather




systems, is essential to simulate such dispersion and quality of impacts of air pollution

on the environment. The purpose of EIA is to determine whether concentrations are

likely to encounter at fixed locations (Know as the receptor), due to the given sources

(locations and rates of emission known) under idealized atmospheric conditions.

3.1.3 Ambient air quality

Ambient air quality was monitored at 05 stations for PM10, PM2.5, SO2 and NO2

parameters in the study area viz., during the Summer Season (March to May 2015),

Monsoon Season (June to August 2015) & Winter Season (September to November

2015) AAQM was carried out on 24hrly basis on weekly twice mode continuously for

one single month in each season viz., March, July & November 2015. The Results reveal

that, ambient air quality in the study area in well within the NAAQ standards and

found to be good and satisfactory.

3.1.4 Ambient Noise levels

The ambient noise levels were monitored at 5 locations and compared with

Residential standards and the results reveal that, the noise levels in the study area

ranging from 40.94 - 43.7 dB(A) for day and 33.7-35.07 dB(A) for night time during Pre-

Monsoon season. Similarly, during Monsoon season, the noise levels in the monitored

locations are ranging from 40.99 - 43.93 dB(A) for day time and 34.06-37.16 dB(A) for

night time. The noise levels during Post-Monsoon season is ranging between 50.68-

54.86 dB(A) for day time and 41.57 - 43.79 dB(A) for night time. Overall, the noise

levels in all the seasons were observed to be well within the CPCB standards.

3.1.5 Seismicity

The proposed project area is located in the Zone-II of Seismic Zoning Map of India.

Hence, the area is very less prone to Earthquakes.

3.1.6 Geology and Minerals

The main rock formations in the study area and the geological succession are

Quaternary - Recent Alluvial deposits - Unconformity

Algonkian - Dolerite dykes, pegmatite and quartz veins- Unconformity

Precambrian - Clospet granites, limestone, phyllites, Mica Hornblende,

quartzite and basic igneous rocks of Dharwar system

Archaean - Peninsular gneiss, amphibolites etc.

3.1.7 Soil characteristics

Most of the study area especially towards riverine slopes Typic Chromosterts Fine,

Montmorillontic, Vertic (Black cotton) type of soil is extensively found in the region. The

command area is comprising of Typic Chromosterts Fine, Montmorillontic, Vertic

(Black cotton) type of soil, Very fine Montmorillontic, Typic pellusters (Clay soil) and

Clayey-skeletal, mixed, Typic Rhodusalfs (Red soil) types of soils.

The black cotton soil is rich in bases (alkaline condition) and has a very high water

holding capacity. The soils in the project area are mostly black soil, while the red and

mixed soils constitute only 20 percent, and are two to four feet deep, heavy in texture,

with 45 to 55 per cent clay and contain free calcium carbonate throughout the

profile. There is generally a zone of salt concentration in the soil profile at a depth of

18 to 36 inches, the principal salt being gypsum. Below the gypsum layer occurs

„murrum‟ which is practically impermeable to water, so that the internal drainage of

the soil is lateral rather than vertical within the profile.




Table 6 Nutrient index in command area

Sl No Parameter Nutrient index Remarks

1 Organic carbon (OC) 3.0 High

2 Available phosphorus (P) 1.077 Low

3 Available potassium (K) 0.88 Low

3.1.8 Hydrology

Haveri district is generally a gently undulating plain except for the hilly area on the

western most part of the district bordering Uttara Kannada district and ridges on

southernmost parts of the district, which forms part of Hirekerur taluk. The landmass of

the district is situated between the elevations of 515 to 732 m above MSL. The Tunga-

Bhadra River flowing on the eastern border of the district is the only perennial River in

the district. The Varada and Kumudvati Rivers are major tributaries of Tungabhadra

and River Dharma a major tributary of Varada drains the district. All the Rivers in the

district together with their tributaries exhibit dendritic drainage pattern and they form

part of Krishna main basin.

3.1.9 Surface Water

The baseline status of water quality in the study area was established. Water samples

were collected from 10 locations (5 No. of surface water & 5 No. of ground water) in

the study area during Summer Season (March to May 2015), Monsoon Season (June to

August 2015) & Winter Season (September to November, 2015).

In summer season, the physico-chemical parameters for Varada river (upstream, lift

point and downstream) were well within the standards. Total dissolved solids in

upstream and downstream locations are reporting 1760 mg/l and 421 mg/l

respectively and whereas near lift point the TDS was observed to be at 412 mg/l.

Dissolved oxygen was observed to be in the range of 5.7-6.1 mg/l.

In monsoon season, Total dissolved solids at all the locations were considerably

reduced in monsoon season compared to post-monsoon season and reporting 66-71

mg/l. Iron was reported very high and exceeding the standards at all the locations

and ranging between 0.57-0.83 mg/l. Higher concentration of iron was noticed in

rainy season due to the dissolution of ferrous iron in the Varada river catchment area

(geological condition). Dissolved oxygen was observed to be in the range of 6 - 6.9

mg/l. The TDS in tank water is ranging between 564-674 mg/l.

In winter season, Total dissolved solids at all the locations were considerably regained

its situation when compared to monsoon season and ranging 210 mg/l and 264 mg/l

at lift point and downstream locations. In upstream location TDS was observed to be

1992 mg/l which is close to the permissible limits. Iron back to the normal situation and

well within its prescribed limits. Dissolved oxygen was observed to be in the range of

6.6 - 7.2 mg/l.

3.1.10 Ground Water

In summer season, Total dissolved solids in upstream and downstream locations were

1760 mg/l and 421 mg/l respectively and whereas near lift point the TDS was observed

to be at 412 mg/l.

In monsoon season, Iron was reported very high and exceeding the standards at all

the locations and ranging between 0.57-0.83 mg/l. Dissolved oxygen was observed to

be in the range of 6 - 6.9 mg/l. The TDS in tank water is ranging between 564-674 mg/l.

In winter season, the Total Hardness was exceeding the standard at Teggihalli (1000

mg/l) and Challal (640 mg/l), Calcium(208 mg/l), Magnesium (116.6 mg/l) was




exceeding the standards slightly at Teggihalli. Nitrate was almost close to the

permissible limit (43.57 mg/l). At Challal, the Calcium (160 mg/l) and Magnesium (250

mg/l) exceeding the standards.

3.2 Biological Environment

3.2.1 Flora

A total of 63 species of trees, 28 species of shrubs, 51 species of herbs and 35 species

of grasses found in the study area. All the species observed / recorded are common

and no rare, endangered and threatened species found in the region.

3.2.2 Fauna

The study area has poor diversity of wild animals. 12 species of mammals found in the

region. Out of which, Black buck (Antelope cervicapra) belongs to Schedule-I animal

and remaining are common to the region. The avian diversity is fairly good and 43

species of birds recorded in the region. Of which, Indian peafowl (Pavo cristatus),

Black kite (Milvus migrans) and Indian quail (Coturnix chinens) belongs to Schedule-I

category and remaining species belongs to Schedule -IV of the Wildlife (Protection)

Act, 1972. 16 species of butterflies found in the study area and all are common to the

region. No rare, endangered and threatened species found in the region.




3.2.3 Avi Fauna

Few bird species such as Little cormorant, Indian pond heron, Cattle egret, Little egret,

Bar headed goose, Black kite, Green imperial pigeon, Common wood pecker, Brown-

headed barbet were found in the command area.

3.2.4 Amphibians

Common Indian toad was found in the command area.

3.3 Aquatic Ecology

The plankton of the Varada river, inherently, is 'poor' in representation and is subjected

to constant changes (Poor- rich -Poor). As the species and values indicate,

Zooplankton dominated over phytoplankton by both numbers and percentage. The

values presented are an average of three sampling stations viz., Kalasur (project site),

Karjagi (down stream) and Varada bridge(up stream).

The bed of the river in all the stations , where studies were carried-out, was mostly

sandy and Stray cases of boulders in the stations.

The phytoplankton in order of abundance, consists of Chlorophyceae 2-19 nos ./0.38-

9.03%), Bacillariophyceae (2-35 nos./0.31-31.13%) and Myxophyceae (2-47 nos/0.44-

8.15%). The zooplankton represented by Rotifera 4-362 nos./0.88-22.99%), Copepoda (

63-246 nos./10.11-15.62%), Cladocera (3-53 nos./0.32-4.85%), protozoa (5-65 nos./0,.32-

5.44%) and Ostracoda (8-66 nos./1.76-6.68%). The Miscellaneous group represented by

insect remains and vegetative parts formed the least group with minimal

representation ( Insects - 1 - 25 nos./022-4.19% and vegetative parts - 0.3 nos./0.22%).

The phytoplankton on the basis of the taxonomic criteria were represented by

Myxophyceae (Anacystis cyanea, Oscillatoria princeps & Spirulina major),

Chlorophyceae (Volvox aureus, Pandorina simplex, Coelastrum chodati, Cosmarium

granatum, Spirogyra varians and Ulothrix zonata) and Bacillar iophyceae ( Diatoma

vulgare, Fragilaria capucina, Syndera ulna, Surirella striatula, Gyrosigma kutzingi and

Navicula radiosa).

The Zooplankton is represented by Protozoa (Arcella mitrata & Difflugia corona),

Rotifera (Brachionus calcyflorus, Keratella tropica, Notholca acuminata & Filinia

longiseta) , Cladocera (Daphnia magana and Moina micrura), Ostracoda ( Cypris

subglobosa) and Copepoda (cyclops and nauplius). Miscellaneous group is

represented by insects /vegetative fragments only.

4. Anticipated Environmental Impacts & Mitigation Measures

Due to the activities of the project, there will be potential impacts on the environment

of varying magnitude. Most of the impacts are likely to occur during the construction

phase of the project. The following sections reveal the impacts due to the project on

the physical, biological and social environment. Impacts have been assessed based

on the information collected from the screening and feasibility study reports, field

surveys and additional secondary data collected as part of the study. The majority of

the impacts are confined only during the construction stage

4.1 Ambient Air Quality

The construction of the project is expected to last approximately in 24 months. The

initial site clearing will be followed by site preparation activities

Fugitive dust emissions from the project will result from:

Dust entrained during onsite travel on paved and unpaved surfaces;




Dust entrained during aggregate and soil loading and unloading

operations; and

Wind erosion of areas disturbed during construction activities.

Combustion emissions during construction will result from:

Exhaust from the Diesel construction equipment used for site preparation,

excavation, trenching and construction of onsite structures;

Exhaust from pickup trucks and Diesel trucks used to transport workers and

materials around the construction site;

Exhaust from Diesel trucks used to deliver concrete, fuel, and construction

supplies to the construction site; and

Exhaust from automobiles used by workers to commute to the construction

site.

The following mitigation measures will be followed to control potential emissions of

fugitive dust during construction of the project:

HSD with low sulphur content will be used for the construction equipments/

vehicles which has low ash content.

Unpaved roads in the project construction site are watered frequently as

necessary to prevent fugitive dust. All vehicles carrying construction

materials will be covered with tarpaulin to avoid spillage of construction

materials.

All the trucks carrying construction materials to the site shall be inspected

regularly and shall have valid Pollution Under Control (PUC) certificate.

Labors camps shall be provided with LPG facilities.

Usage of PPEs like nose masks will be provided.

4.2 Ambient Noise Level

During construction phase, various sources of noise pollution arise due to operation of

machineries like concrete plant, cranes, batch plants, material lifting operations,

communication noise, including DG sets etc., Other source of noise pollution includes

movement of vehicles for unloading of construction materials, fabrication, handling of

equipments. Construction activities are expected to produce noise levels in the range

of 80 – 95 dB (A).

PPEs such as, ear plugs and ear muffs will be provided to the workers.

Six monthly maintenance and servicing of construction equipments/

vehicles.

Acoustic enclosures will be provided for DG sets

Construction activities shall be restricted only to day time and there will not

be any construction during evening and night hours to avoid the

psychological effects on surrounding population and biota.

4.3 Water Environment

The quality of water resources both surface and ground water may also deteriorate if

solid waste management practices are not adopted in the labour camps of the

project during peak construction phase.

Improper treatment of sewage from labor camps leads to infiltration into the

subsurface soil and finally affects the ground water of the region. This will create




unaesthetic conditions in the site, attracts mosquitoes/flies, thereby chances of

deteriorating the health of the workers in unhygienic conditions. Improper disposal of

construction debris, used oil, diesel for DG sets, etc will result in ground water

contamination and in turn affecting drainage of the area.

The mitigation measures include;

The sewage generated from the labour camps shall be treated in the

Septic Tank and Soak Pits designed and constructed as per IS 2470 Part-I &

Part-II.

There will be no open discharge of sewage from labour camps and the

labour camps will be provided with sufficient bathrooms and toilets.

Periodical health check-ups for labors will be done.

Construction debris will be reused at site, used oil generated from the DG

sets will be stored separately and handed over to KSPCB authorized

recyclers.

During construction of intake canal, the river course and the point of

contact of intake canal will be provided with sand bags

4.4. Land Environment

Temporary loss of soil may be envisaged during the construction phase during

construction of temporary offices, workers camps, stockyards, borrow areas etc.

Compaction of soil may occur, particularly on haul roads during site clearance due to

movement of heavy machinery and vehicles and during setting up of construction

camps and stockyards.

Mitigation measures:

Labour camps will be constructed in the vacant/ barren lands so that

impact on agricultural lands are nullified.

Maintenance and period repair of machineries will not be taken up in the

project site vicinity. Maintenance of DG sets will be done at the vendors

place and will not be taken up near project site.

4.5 Biological Environment

During construction, due to the fugitive dust, photosynthetic activity would

be reduced and leads of wilting of plants.

Use of river water for domestic needs by labors will bear riverine water

pollution and affects aquatic biota.

Use of fire wood for labor camps results in cutting of trees.

Construction equipment / vehicles washing leads to oil spillages into river

and leads to reduction in dissolved oxygen levels.

Improper disposal of construction materials and domestic wastes leads

eutrophication.

Mitigation measures:

Periodical water sprinkling in and around the construction areas including

access roads to avoid fugitive dust generation.

Labor camps shall be located 1 Km away from the river course and

imposing restrictions for not using the river water for domestic purpose.

Labors camps shall be provided with LPG facilities.




Construction equipment / vehicles washing shall be undertaken at

authorized service stations.

Security personnel near river course and sign boards will be erected to

educate the labors.

4.6 Evaluation Impacts

Matrix method was used to identify interactions between various project activities and

environmental parameters and components. Later, a weightage of 1-10 shall be

given to the impacts based on the significance of the impacts. The impacts are

quantified „with‟ and „without‟ EMP. The criteria adopted for weightage are given

below;

7. Social Impact Assessment

The proposed project is for irrigating 15500 ha of land covering 30 drought prone

villages in Karnataka, utilizing 1.5 TMC water through lift irrigation from the upstream

of an already existing Kalasur barrage across Varada river, in Kalasur Viliage,

Savanur Taluka, Haveri District of Karnataka . Out of which 1.35 TMC of water will be

utilized for irrigation purpose by adapting drip irrigation with piped conveyance

system and remaining 0.15 TMC will be used for filling of 11 minor tanks to provide

drinking water facility and sub soil replenishment.

7.1 Demographic profile of the villages

The Project Influence area covers eight villages viz., Savanur, Hosahalli, Thondur,

Kalasur, Thalahalli, Jallapur, Hattimattur, Kalakond in Karnataka State. The brief

socio-economic profile of the Study area villages is given in the following sub-

sections.

7.2 Impact of the project

During the project construction phase and operation-management phase

additional employment will be generated.




The only negative impact is that some people will lose their agricultural land for the

project construction purposes and they will be sufficiently compensated as per rules.

Since no residential or commercial properties affected, there is no need for any

displacement and hence resettlement /rehabilitation is not involved.

Villagers have some additional demands for construction of linking roads, sanitation

facilities etc which will also be duly attended by the Govt, especially since this

backward villages are in the hit list for the developmental interventions.

So overall impact of the project is positive which will bring long term development/

growth in the development map of these villages.

8. Project Benefits

Filling of 11 MI tanks helps in recharging the ground water table helps in

sub soil replishment. It also provides direct drinking water access to

domestic animals.

The project improves total farm output and hence raises farm income.

Project improves yields through reduced crop loss due to erratic,

unreliable or insufficient rainfall.

It allows a greater area of land to be used for crops in areas where rain

fed production is impossible or marginal. Presently, 7750 Ha practicing

rainfed agriculture and due to the implementation of the scheme 15500

ha will be under irrigation.

Extensive agricultural production supplies raw materials to the nearby

small scale industries thereby increasing the economy in the region.

Increased benefits from flood control, soil erosion, etc

Altogether, population of 48695 belonging to 9501 families in the

command area will be benefitted directly under the scheme.

Direct employment opportunities for 100 people during construction

phase and 30 people during operation phase of the project. Further,

indirectly labor opportunities will be substantially improved since larger

area will be brought under irrigation.

It improves fodder crops and in turn dairy farming in the command area.

The existing Kalasur barrage will be utilised for the scheme and hence less

environmental impacts.

Water conservation through adoption of drip irrigation for the entire

15500 command area.

Zero water logging and salinity problems. Weed and disease reduction

due to adoption of micro irrigation.

The project requires only 188 Ha for implementation of the scheme and

does not envisages rehabilitation and resettlement.

No tree cutting and no forest land required for implementation of the

scheme. Agro forestry shall be taken up in command area and it

improves the ecosystem services.




9. Environmental Management Plan

Although agriculture is usually associated with its positive impacts on human life, irrigation practices may be associated with

impacts on environmental conditions, which may eventually curtail the sustainability of irrigation projects. For this reason,

Environmental Impact Assessment (EIA) has been recognized as an integral part of the early planning studies of irrigation projects in

order to identify any expected negative impacts and suggest the necessary mitigation plans to curb these impacts through

formation of Environmental Management Plan (EMP).

Haveri District, Karnataka of Final EIA Report


9.1 Catchment Area Treatment (CAT) plan

Soil and Water are the two most important Natural resources which have a direct

bearing on agricultural production. These resources have to be used judiciously to

obtain optimum of yield of crops. The recommended soil and moisture conservation

measures for Northern Dry zone are as follows:

Contour bunds with waste weirs.

Graded bunds/Graded border strips.

Zing terraces with raised waste weirs.

Diversion Drains/Water ways.

Reducing wind erosion of soil by growing wind breaks (vegetation cover).

Gully plugging.

In over-grazed land silvi pastoral systems, which in irrigated land yield

enough green fodder to cattle population.

Grazing animals should be kept in stalls.

Agro forestry and Agro horticulture systems to meet various needs of

farmers, crop residue of this adds to the soil and increases carbon

content and biotic activity.

Harvesting of runoff and impounding through appropriate structures.

Drainage line treatments to improve the flow and avoid nala course

clogging.

9.1.1 Recommended soil conservation practices for CAT

Karnataka is a pioneer in implementing watershed programmes since 1983. Dry land

development boards were constituted at in the divisional level, model watersheds,

district level macro watershed programs, DPAP, DDP, IWDP, WGDP, RVP, NWDPRA

and more recently from April 2008 Integrated Watershed Development Programme

(IWMP).A state level perspective and Strategic Plan (SPSP) is prepared for the state

and entire area (120.85 lakh ha) is contemplated to be treated by the end of XIV

plan period, on 60:40 ratio between center and state.

In the district of Haveri, out of 894 micro watersheds with 4, 29,937 ha, 233 micro

watersheds has been treated covering an area of 843400 ha have been treated

under catchment area Protection treatments. Till the end of the sixth five year plan,

nearly Rs. 51crores was spent on improvement of about 843400 ha of the land with

various soil and water conservation measures.261 watersheds are proposed to be

treated in the next 18 years.

Some of the methods suggested for soil conservation for Savanur catchment area

and other details are provided below.

Gully plugging

This prevents the eroding and down-cutting of gully beds headwords while they

encourage the deposition of silt load and create a micro-environment for the

establishment of vegetative covers. Gully plugs act as grade stabilization structures.

The specifications for gully plug are as follows;

The gullies would be treated with engineering/mechanical as well as vegetative

methods. Check dams are recommended for some areas to promote growth of

vegetation that will consequently lead to the stabilization of the slopes area and

prevent further deepening of gullies and consequent erosion. For controlling the

gullies, the erosive velocities are reduced by flattening out the steep gradient of the

gully. This is achieved by constructing a series of check dam which transform the

longitudinal gradient into a series of steps with low risers and long flat treads.

Different types of check dams would be required for different conditions comprising

different materials, depending upon the site conditions and by using the locally

available materials. This is often the most acceptable soil conservation measures

that can easily establish and should form a dense thicket near the ground level

when planted in close vicinity. The following materials are recommended for the

purpose.

Brushwood check dam

Dry rubble stone masonry (DRSM)

Check dams with stones available at the site

Combination of DRSM and crate works – for moderate to deep gullies

with locally available stones at sites

The advantage of brushwood check dams is that they are quick and easy to

construct and are inexpensive as they are constructed by using readily available

materials at the site. In addition to the vegetative measures used for stabilization of

gullies, temporary or permanent mechanical measures are used as supplementary

measures to prevent the washing away of young plantations by large volume of

runoff. The gullies get stabilized over a period of time with the establishment of




vegetative cover. With passage of time mechanical structures weaken and

vegetative measures get strengthened.

The drainage basin of the river, usually referred to as catchment area needs some

kind of treatment in the overall interest of the development of the area extending

along the river with a view to improve land management through biological and

engineering measures, with the objective of arresting soil erosion and improve its

vegetation, and control over grazing by cattle.

The catchment area treatment involves intensive and highly technical measures,

which require the expertise of technical skill. The watershed committees have to be

constituted at the panchayath level in the Panchayath covered in the proposed

catchment areas of Savanur spread over in the jurisdiction of Shimoga, Haveri and

Uttara Kannada Districts with the objective of an integrated approach involving

multi disciplinary experts dealing with forest, agriculture, horticulture, watershed,

sociologists, besides local panchayat members and community members.

The area under each watershed has been planned on the basis of Land use / land

cover and topographic conditions. The total area proposed for treatment is

131308.2ha, in the Savanur project basin.

9.2 Command Area Development Plan

9.2.1 Water Users’ Association (WUA)

The modern irrigation management aims at high efficiency of water conveyance

and appropriate methods of water application, through participatory irrigation

management at each stage of irrigation development. In Karnataka, it is essential to

promote and implement the theme of participatory irrigation management in all the

Irrigation projects through formation of Water Users‟ Association. The construction of

OFD works will be taken up after formation of WUAs under the supervision of CADA,

Belgaum.

The efficient management of irrigation water for maximizing productivity requires,

firstly the efficient on farm water management and secondly the optimization of the

use of water and land, through appropriate methods of water application. The

efficient on-farm water management is related to water delivery system and allied




works in the command area, which distributes the water to each farm. The items of

works pertaining to on farm water management are termed as “On Farm

Development Works”.

The On Farm Development works comprise of the following,

Maintenance of disnets, sumps

Control structures

Maintenance of Automation

Surface Drainage system

Farm roads

Land forming (Smoothening / grading/leveling)

9.2.2 Green belt development plan

9.2.2.1 Plantation around intake canal and jack well cum pump house

Green belt development activities will be taken up on either side of the intake canal

and in and around jack well cum pump house. The details are given below;

9.2.2.2 Agro forestry activates in command area

Agro-forestry refers to the practice of Agriculture and Forestry in the same piece of

land. The Karnataka Forest Department (KFD) has accorded high emphasis on farm

forestry as a component in the afforestation programmes. The sector of Agro-forestry

or Farm Forestry has a good potential as most of the agriculture lands are devoid of

any trees, in the district. The trees if planted on the bunds and on the boundary of

the lands, protect the crops from the desiccating high winds and also provide

additional income from the trees to the farmer apart from providing him fodder and

fuel as well.

Silvi-Pasture refers to the planting of the trees in a predominately grassland so as to

provide fodder all the year round. This afforestation is aimed at not only addition of

tree species, but also addition of highly nutritive and palatable grass species in the

area, thereby providing much needed nutritious fodder to the livestock population.

9.2.2.3 Plan for conservation of Wild animals

Based on the direct observations of the survey teams; indirect and circumstantial

evidence; information furnished by the forest dwelling communities, the forest and

wildlife department, it appears that Blackbuck (Antilope cervicapra) and Indian pea

fowl (Pavus cristatus) is observed regularly in the study area. The project proponents

and contractors shall follow the following strategies in conserving the wildlife in

association with Karnataka Forest Dept.,

Eco-development works in and around Kappad hill to provide the

essential benefits to the occupants of enclosures and villages

respectively to ensure their support and willing participation in wildlife

conservation.

Encourage appropriate monitoring and research works to develop

programmes and plans, and thereby tackle the identified problems.

Facilitate education and awareness creation, facilities for the benefit of

all sections of population and especially students. Create awareness on

the need to conserve our natural bio-resources through various mass

media and other means.

Implementation of habitat restoration and improvement measures

wherever necessary.

Prevention of outbreak of contagious diseases among wild animals by

taking prophylactic measures among domestic animals entering forests.

Construction of crop protection structures like fences, trenches and walls,

etc.

Identification of restoration of corridors to facilitate free movement of

animals between and around forests

Settle adequate compensation to the persons for death or damage

caused by wild animals.

Integrate the wildlife Protected Areas on a watershed or landscape basis

with other sectors like Rural Development, Animal Husbandry, etc. for the

sustained conservation and development of the area.

9.3 Fisheries Development Plan

It is suggested to install suitable mesh-sized screens at the diversion point at In-take

distribution points. Screens of large-sized mesh, over and above 5 cm at main in-take

point, few meters away from it with mesh-size of 20 mm to prevent entry of large,

medium carpe, weed fish and also major/minor catfish Present.

In addition, around 5 lakhs fingerlings (over 75 mm in total length) comprised of

Gangetic carp - Catla catla - 40.0%, Labeo rohita. 30.0% and Cirrhinus mrigala-

10.07% are to be introduced annually in the river Varada above the Project site. The

Authorities related to the Propose Project could contribute their might and service to

this developmental strategy to facilitate enrichment of riverine fish fauna and also to

provide quite an opportunity to the fisher folk of the area to elk-out their livelihood

by engagiing in their profession. The indents for the required fish seed be forward to

the Fisheries Development Officer, Tungabhadra Dam Post, Hospet taluk , Bellary:

district, Assistant Director of Fisheries, Haveri taluk , Haveri district, by around January

to March of each year to ensure supply of the required stocking material 'and the

species composition. The entire process envisages helps in augmenting fish

production in the river/reservoir complex in question. The total cost involved will be

around 5.00 lakhs only. The fish Seed slated to be introduced, preferably, be

undertaken between the Varada bridge (near Haveri and Domburmattur).

9.5 Public Health Delivery plan

Periodical health checkups (once in 6 months) is proposed for construction labors.

District Health Hospital, Haveri is located at a distance of 9 Km from the construction

site, necessary arrangements will be done to consult the Hospital.

9.6 Sanitary and Solid Waste Management Plan

Solid waste generated at the labor camps will be collected in different

bins and the recyclable waste will be handed over to the Haveri

Municipal authority.

Provision of toilets and bathrooms will be provided at labor camp to

avoid open defecation.




The dometic waste water will be treated with septic tank and soak pit.

9.7 Ground water management plan

Due to the adoption of drip irrigation facilities, drawl of groundwater is likely to

decrease and vast areas will be put to use for cultivation. The crop acreage is

increased substantially. As such the groundwater levels will increase and further

exploitation will be minimized. After a few years the monitoring programme should

be envisaged to study the potential of groundwater and conjunctive management

could be planned.
