Soil and water conservation technologies and approaches are critical factors toward the sustainable use of the natural resource base for agriculture in Asia. It is estimated that about 80 percent of all available water supply in the region is mainly used for irrigation. Increasing withdrawals of water for food production is one of the main causes of water scarcity, which several countries are facing today. Meanwhile, soil erosion continuously places many parts of the world in a critical situation. Estimates show that about 35 percent of the earth’s total land surface is significantly degraded. Low crop productivity is also traced to low soil fertility levels.
The widespread concern over the degradation of soil and water resources has led to great efforts by governments and scientists in the Asian region to develop technologies appropriate for small-scale farmers. These scientific solutions to preserve and conserve the natural resource base for agriculture involves strategies that cut across social, environmental, and political boundaries.
