Soil and water are the basic resources and these must be conserved as carefully as
possible. The pressure of increasing population neutralizes all efforts to raise the standard of
living, while loss of fertility in the soil itself nullifies the value of any improvements made.
This calls for more systematic resource conservation efforts. It is well known to every farmer
that it is the top soil layer, which sustains agricultural production. Once this layer is lost or
eroded, nothing can be done to replace it within a short period of time. Climate and
hydrology, soil topography, soil surface conditions and their interactions are major factors
affecting erosion-sedimentation processes. The semi–arid regions with few intense rainfall
events and poor soil cover condition produce more sediment per unit area. But the man’s
intervention has disturbed the natural equilibrium and intensive and extensive agriculture has
become a dominant factor in accelerating land degradation. The ever-increasing population
pressure has brought intensive cultivation of land to the forefront through irrigated
agriculture. No doubt these practices have resulted in a great increase in productivity, but
they have resulted in large-scale water logging. Cultivable wastelands are increasing in the
agricultural fields due to improper land management. The obvious remedy for this is to
follow soil and moisture conservation practices along with integrated nutrient supply system
for improvement of soil fertility as well as crop productivity on sustained basis. Soil
conservation in any form is the only known way to protect the productive lands. In a
predominantly agricultural country like India, where droughts and floods cause chronic food
scarcity, adequate soil conservation programme, not only increases crop yield, it also
prevents further deterioration of land. Methods to control surface runoff and soil associated
erosion have been practiced in India from times immemorial.
