Terrestrial flora

! Lebanese forests have been the suppliers ofhigh quality timber to the Mediterranean people.

! The intensive woodcutting over severalmillennia, followed by the expansion of agro-pastoral activities and subsequent urbanizationresulted in only relic forest patches and scrubvegetation remaining. Today, Lebanon's forestcover is estimated at 70.000 ha

Socio-economic Situation

Lebanon is divided into 6 Mouhafazats or governorates:

Beirut, North-Lebanon, South-Lebanon, Nabatieh,Mount-Lebanon and Bekaa

! The economy of Bekaa is predominatelyagricultural, as are those of the North and South.

! The coastal cities Beirut, Tripoli (North), Saida(South) have large ports and mostly engaged incommerce and other services (tourism).

! The bulk of industry is concentrated in MountLebanon, the suburbs of Beirut and the coastal area ofthe North.

UNCCD

! Lebanon signed and ratified the UNCCD (1995)

! UNCCD convention(1994) powerful instrumentfor sustainable natural resource management inaffected regions

! > 190 countries are involved

! In 2003 the elaboration of National ActionProgramme (NAP) to combat desertification inLebanon

Ministry of Agriculture/ UNDP/ GTZ

National Action Programme

The Lebanese government is making efforts tokeep combating desertification as a priority taskwithin the framework of sustainabledevelopment of the country (?).

Identification of the factors contributing todesertification in the relevant socio-economic,biological and geographic context; and definingpractical measures for combatingdesertification.

Desertification prone areasSuperficial processes

Direct & indirect naturalIntensive rainfall:

floods(64% of Lebaneseterritory has complexlandform: steep lands).

Land sliding is another processmodifying landscape and ismainly due to restrictednatural drainage.

Human induced- Deforestation & urban

expansion

- Soil Salinization (Sea waterintrusion, bad irrigationpractices & fertilizerapplication)

- Dumping of solid & liquidwastes in open inland waterbodies & reservoirs resultingin water contamination

- Monoculture and unsustainablerotation

Inappropriate practices leading to land

degradation

! Intensification of cropping systems (monoculture andmultiple cropping, cultivation under greenhouses,plantation of high yielding cash crops)

! Intensive agricultural production requiring more inputs:water, fertilizers, pesticides and herbicides

! Poor management and insufficient technical know-how! Excessive and uncontrolled pumping of groundwater for

agriculture, especially in dry years, resulting in thelowering of the groundwater table in many places and insaline water intrusion along coastal areas.

! Inadequate use of drip irrigation and fertigation systemsresulting in salinity

! Excessive fertilizer use resulting in a higher level ofnitrates in groundwater

Impact of Land degradation

!Water erosion

! Soil salinization

! Soil pollution: In the absence of proper land usezoning, industry, manufacturing and agriculturalactivities resulted in soil contamination with Ni,Cr, Cd and Pb in some limited areas of CentralBekaa (Darwish et al., 1999)

! Urban expansion

! Soil related stresses

Lebanon / UNCCD

The Lebanese government is committed tocombating desertification:

- It has initiated a large scale Reforestationprogram and has allocated approx. $16 millionto this end.

- It is active in fighting the root causes behindland degradation by promoting the Developmentof rural areas and reducing regional disparities(financed through a mix of budgetary resourcesand donor agencies).> than 15 NGOs are active.

Water harvestResources mobilization

to move forward

! Lebanon’s remarkable decade of reconstructionfollowing a devastating 15 year war saw strongeconomic growth gradually slide to a halt by 1999.

! The cost of rebuilding highways, schools, airports,seaports, housing, power stations, and governmentbuildings pushed public debt to about 180% of GDP(2001) and led to chronic budgetary problems

! A second challenge is to tackle poverty and incomedisparities. The UN estimates that one third of Lebaneselack basic needs.

! Lebanon would therefore be seeking for assistance fromthe international community.

• GDP-mining contributes 36.5%

Poverty

• Mining main contributor of GDP but employs 5%workforce

• Slow development labour-intensive industries,labour market rigidities coupled low skill levelscontribute high unemployment and skeweddistribution income. Gini coefficient 0.57(2002/3)

• Poverty fallen over past 3 decades, still highabout 1/3 population living under US$ 1 a day.

•467 million heads of cattle graze on 11 million Ha of pasture land

•Livestock density is 42 animals /Ha as against the threshold level of 5 /Ha

•An estimated 100 million cow units graze in forests as against asustainable level of 31 million per Ha

Major environmental issues:

1. Land degradation: (due to water erosion-Assam, wind erosion-

Rajasthan, water logging-Ganga.Brahmaputra and over grazing)

1. Degradation of forests: It is estimated that after independence the

country has lost 4696 million Ha forest land for non-forestry purposes

•River valley projects, agriculture, illegal occupation, industries andtownships, transmission lines and roads etc.

3. Water pollution

4. Air pollution, carbon emission

•Air pollution (due to vehicular emissions, untreated industrial smoke)

•Carbon emission 251 million MT (2001)

•Forest per capita 0.08 Ha (against 0.47 Ha)

•Forests 68 (1990-91), 68.86 (97-98)

•Population growth rate 1.93% (2.14% in 90-91)
