In India, out of million hectares of geographical area, 68 million hectares are critically degraded while million hectares are severely eroded. That's why soil and water should be given first priority from the conservation point of view and appropriate methods should be used to ensure their sustainability and future availability. Status of global land degradation is shown in Fig.
