The land use/land cover has been dramatically changing in Asian countries in the last few decades due to the population pressure. Generally, the forested lands have been converted into agricultural lands, as well as the productivity has been improved because of more irrigation, use of chemical fertilizer, mechanization and so on. There is, however, increasing concern about some of the irrigation potential created but not brought into the functional system, lower operating efficiency, lesser crop productivity etc. Improvement in agricultural productivity has become a necessity due to the limitations in expansion of cultivated acreage and ever increasing food demand. A large number of irrigation projects have been commissioned in India in the postindependence era for improving food production and economic development. These irrigated croplands though limited to about 30 percent of the gross cropped area in India, contribute more than 50 percent of the total agricultural production. However, optimistic forecasting of production cannot be expected, because there are limits of suitable cropland, limitations of productivity and shortage of water resources.
