The need is:<br />
• To check land degradation<br />
• To reduce excessive biotic pressure by containing the number and increase <strong>of</strong> livestock<br />
• To check cultivation on sloping lands without adequate precautions <strong>of</strong> soil and water<br />
conservation measures<br />
• To discourage cultivation along susceptible nallah beds<br />
• To check Faulty agriculture techniques<br />
• To check Uncontrolled grazing and developed cattle tracks<br />
• To check Deforestation <strong>of</strong> steep slopes<br />
• To check erosive velocity <strong>of</strong> run<strong>of</strong>f, store Run<strong>of</strong>f, to arrest silt carried by run<strong>of</strong>f and to recharge<br />
Ground Water structures life Earthen check dams, gully plugs, Bank Stabilisation, Loose stone<br />
check Dams, Gabions, Earthen embankment (Nadi) and Anicuts would be taken up.
