Explanation:

 Keeping in view the ecological, soil conservation, food, fuel, fodder and other needs of the growing population and environmental needs, a sustainable land use programme based on watershed basis, is required to be evolved. “Watershed management” is thus on integration of technologies within the natural boundaries of drainage area for optimum development of land, water and plant resources to meet the basic needs of the people in sustained manner. In this programme the development is not confined just to agricultural lands alone but covers the entire watershed area starting from the highest point (ridge line) to the out let of the nallah or natural stream, this involves implementation of ameliorative measures on barren hill slopes marginal lands, privately owned lands and badly cut nallahs and river courses.
