The watershed thus is a physio graphic unit and can be used conveniently for integrated development of small natural unit areas. The watershed development is a holistic approach. It includes programmes for soil and moisture conservation, water harvesting, afforestation, horticulture, pasture development and upgradation of community land resources. Several such programmes have been taken up recently by the central and state governments, with promising results.

(ii) Meaning of Rainwater Harvesting:

It is a technique of increasing the recharge of groundwater by capturing and storing rainwater by constructing structures, such as dug wells, percolation pits, check dams, Rainwater is stored in groundwater reservoirs by adopting artificial recharge, techniques to meet the household needs through storage in tanks.
