SUMMARY Currently, only 6% of the 15% of land in Afghanistan is usable and, if all the refugees were to return, problems of land ownership and adequacy of available land are inevitable. Natural forests have been severely degraded. Due to the nature of the topography and the arid climate, vast areas are subject to soil erosion. Loss of vegetation and soil humus have created ever more arid conditions. Abandoning the lands, poor reclamation schemes, overgrazing and destruction of vegetation for fuelwood have all caused desertifkation. The biological productivity of pastures has also deteriorated. This reduced productivity has affected livestock and has caused dramatic changes to the patterns of wildlife populations. Soil salinization and waterlogged lands are common. Farmland and pastures have been contaminated by landmines. Heavy concentrations of air-borne particulates and considerable amounts of transboundary pollutants from the Aral Sea have been found. Use of chemicals and the machinery of war have damaged the ecosystems. Collection of plants and animals is unregulated and has resulted in excessive removal or extermination of some species endemic to the Hindu Kush. Uprooting of some plants and dynamite fishing are increasing and a disturbing number of fauna and flora are endangered. Agriculture is traditional, and natural resources are not being used in a sustainable way. A sound environmental strategy needs to be formulated and adopted.
