Conservation of resources is essential because some resources like minerals are non renewable and need conservation for future generations. Conservation is a judicious and careful management of resources by man as improper and overuse can deplete them leading to many ecological problems.
Three methods of soil conservation are:
(i) Terrace farming : Cutting of hilly areas into steps to reduce the flow of running water.
(ii) Strip cropping : Growing of crops in long strips.
(iii) Planting of shelter belts : Shrubs and trees are planted along fields to control the force of wind.
