Table 2. Environmental issues and their main direct factors in Central and South Asia

SOIL RESOURCES WATER RESOURCES AIR FOREST RESOURCES BIO-DIVERSITY URBAN ENVIRONMENT MARINE RESOURCES
EROSION CHEMICAL DEGRADATION, POLLUTION LOSS TO HUMAN SETTLEMENTS
INDUCED SCARCITY POLLUTION SALINIZATION POLLUTION DEGRADATION ENDANGERED SPECIES CONGESTION, NUISANCES POLLUTION PHYSICAL DISTURBANCE

Azerbaijan

(Unsound irriga-tion and agricul-tural policies) (Excess use of pesticides; oil; industries) Lack of fresh-water resources. Half of main rivers polluted. (Some unsound irrigation projects) (Industries, heating, powerplants) Deforestation is serious. Some fish species lost in Caspian Sea. Many land species endangered. Poor water supply. Unsound waste disposal/ sewerage. Caspian Sea contaminated (coastal drilling etc.).

Kazakhstan

(Grain mono-culture, unsound irrigation etc.) (Radioactive wastes, salini-zation in irrigated areas etc.) Lack of fresh-water resources. Contamination in industrial areas, or by agricultural chemicals. High levels of pollution in places. Acid rain. Some regions suffer from serious forest loss. Plant diversity altered by over stocking. Concentration of industrial wastes in Eastern Kazakhstan. Unsound water use reduced Aral Sea area by half.

Iran

1.5 billion tonnes lost p.a. (deforestation, overgrazing) (Contamination from domestic and industrial wastes) (Industrial and slaughterhouse discharges) (Household, industrial and vehicle emissions) "Stagerring rate" of deforestation. Fauna and flora affected by war and its consequences. (Domestic and industrial wastes, oil spills)

Afghanistan

(Pollution by agrochemicals) (Poor sanitation infrastructure) Water related diseases. Deforestation is a major problem. Cf. Kunar, Nuristan. Overcrowding in major cities (rural exodus).

Pakistan

(Overgrazing) Waterlogging, salinization. Falling ground water tables in arid regions. Wastage. (Human/organic waste, industrial effluents, chemical fertilizers etc) Serious hazard in all major cities (car emissions). (Overgrazing) Deforestation, rangeland degradation. Marine/aquatic species destroyed or threatened by industrial discharges. Mangroves affected by expansion of irrigated agriculture.

India

(Intensive cultivation, overgrazing) Loss of organic and micro-nutrients (intensive cultivation) Loss of land to urban and village growth. Few people have regular access to potable water. (Community wastes, industrial effluents, fertilizers/ pesticides) (Overutilization of ground water) (Outdated industrial plants) (Shifting cultivation; fuelwood collection; overgrazing) (Protected areas are far apart. Plantations replace natural forests) Unplanned urbanization, pollution, lack of water and sanitation. (Mangroves and coral reefs very vulnerable to human activities)

Nepal

(Overexploitation, floods) (Excessive use of chemicals) (Industrial discharges) (Industrial discharges) (Fuelwood/fodder/ timber extraction, agricultural expansion) (Poaching) Noise pollution. Hazardous wastes.

Bhutan

(Unsound cultivation methods, road and channel construction) (Poor management) (Organic pollution from human settlements) (Industry; clearance for farming; overgrazing, fuelwood) Wastes; sanitation is rudimentary. (Oil handling, wastes)

Bangladesh

(Floods, sand deposition, poor agricultural practices) Soil depletion, pollution by pesticides. Loss of good land to urbanization. (Overexploitation of ground water for irrigation, etc.) Lack of safe water, sanitation. There is saline encroachment. (Clearance by landless/small farmers, fuelwood) (Loss of wetlands, forests and natural habitat) Destruction of mangroves (shrimp culture).

Sri Lanka

Soil erosion. (Siltation of reservoirs, river beds, lagoons etc) Industries + raw sewage pollute water bodies. (Vechicle emissions and industries) (Shifting cultivation, timber + fuelwood exploitation) Proliferation of slums and shanties. Industries + raw sewage pollute coastal ecosystems. Coastal erosion.

Maldives

Rapid depletion of freshwater reserves. (Solid waste disposal inadequate) (Overexploita- tion of fuelwood supplies) Contamination of coastal waters by sewage. (Coral mining for building)
