Methods and Guidelines for Assessing Sustainable Use of Soil and Water Resourcesin the Tropics

摘要

Increasing demographic pressures on a finite land resource base is now recognizedas the major problem confronting food security and enhanced quality of life for future generations, particularly in developing countries. A collateral issues is environmental degradation and specifically, land degradaton. It is becoming increasingly recognized that agriculture, particularly the increased use of marginal lands, is an important cause of environmental degradation. The solution recommended is to manage the resources so that they are neither degraded nor depleted and ensure a sustained production for future generations. This monograph provides rationale and some methods for assessing the sustainable use of the land resources.
