This concept aims at (i) providing adequate quantities of fuel wood, fodder and other forest products, (ii) maintaining ecological balance with the help of large scale afforestation on community lands and waste lands in the country. The social forestry is different from farm forestry.

It aims at growing of trees on private lands, on the farm boundaries and private plantations. It is comprised of three schemes (i) Mixed plantations on waste lands (ii) Reafforestations of degraded forests and (iii) Raising of shelter belts.
