P Thirumalai, SM Kumar
The Traditional bound methods of agriculture cultivation is responsible for the low level production. The population growth has also steep that it has resulted in an imbalance in the supply of agriculture products of food grains. This in turn led to a large scale incidence of property, malnutrition and under nutrition. Cropping pattern means the proportion of area under various crops at particular periods of time. Cropping patterns differs from macro to micro regions both in space and time and covered largely by the physicals, cultural and technological factors. land-use and land-cover results from their direct relationship to many of the planet's fundamental characteristics and processes, including the productivity of the land, the diversity of plant and animal species, and the biochemical and hydrological cycles. Land cover is continually molded and transformed by land-use changes such as, for example, when a forest is converted to pasture or crop land. Land-use change is the proximate cause of land-cover change. The underlying driving forces, however, can be traced to a host of economic, technological, institutional, cultural and demographic factors.
