NAUTIYAL R. K. MAIKHURI R. L. SEMWAL New Author K.G. SAXENA School of Environmental Sciences, Jawaharlal Nehru University, New Delhi School of Environmental Sciences, Jawaharlal Nehru University, New Delhi Structure and functions of the agroecosystems in the buffer zone of Nanda Devi Biosphere Reserve (Uttaranchal Himalaya) inhabited by Bhotiya communities were studied using ecological and economic currencies to assess the impact of the conservation policies on the traditional agroecosystems of the buffer zone along an elevational gradient over a period of two years. Implementation of conservation policies has tremendously curtailed the availability of natural resources which sustained the agroecosystems of this region since time immemorial.
