- The detailed plans for the development of hill areas were drawn keeping in view their topographical, ecological, social and economic conditions.
- The programmes are aimed at harnessing the indigenous resources of the hill areas through the development of horticulture, plantation agriculture, animal husbandry, poultry, forestry and small-scale and village industry.
