Much of the earth's population is dependent on agriculture as it provides food for their sustenance. Successful crop production depends to a considerable extent on land and climate. Soil is the main component of land and a fertile soil is essential for crop growth. However, soil fertility declines over the years mainly due to land degradation. Hence, implementing appropriate measures to control land degradation is important. It is the responsibility of the farmers and the governments to take action to control land degradation. Agricultural extension officers are involved in making farmers aware of land degradation and control measures. Planners and policy makers need scientific assessments on land degradation and its implications so that they could advice the relevant authorities who prepare the national programs and budgets.
This book highlights issues related to land degradation, the causal factors and methods of control. The audience is agricultural practitioners and planners as well as students of agriculture. Environmentalists would also benefit by understanding the main issues related to land degradation discussed.
