A Review of Agricultural Land Suitability Classification of Malda District in West Bengal

Green Revolution technologies have allowed the food supply of Asia to satisfy the demand of its rapidly growing population in the past decades; however, the pressure on soil and other resources has intensified. The cultivated area is continuously decreasing because of soil pollution, land abandonment, urbanization, and other reasons. Meanwhile, the population and the demand for food continue to increase. Under such a situation, increasing cropping intensity from monoculture to double or triple cropping in a year is an efficient way to guarantee food security on the amount of agricultural land now available.
