Forests cannot be conserved until and unless conservation of forests is turned into a people's movement and masses are involved in conservation efforts. With this motive twin programmes of social and urban forestry, were launched for rural and urban areas respectively. Social forestry was started in 1976 with the aim of raising quick growing multipurpose plants in common village lands for meeting requirement of fodder, firewood and small timber. This will reduce the dependance on existing forests, lead to development of new green cover, provide employment, reduce pollution and utilise the unused land for benefit of rural masses.

  1. Social forestry

  2. General forestry

  3. Agro forestry

  4. Commercial forestry
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The 'National Commission on Agriculture', Government of India, first used the term social forestry in 1976. It was then that India embarked upon a social forestry project with the aim of taking the pressure off the forests and making use of all unused and fallow land. Government forest areas that are close to human settlement and have been degraded over the years due to human activities needed to be afforested. Trees were to be planted in and around agricultural fields. Plantation of trees along railway lines and roadsides, and river and canal banks were carried out. They were planted in village common land, Government wasteland and panchayat land. 

Social forestry also aims at raising plantations by the common man so as to meet the growing demand for timber, fuel wood, fodder, etc., thereby reducing the pressure on the traditional forest area. This concept of village forests to meet the needs of the rural people is not new. It has existed through the centuries all over the country but it was now given a new character.
