Rangeland,ecological integrity and sustainability:an analysis in the Himalayan Mountain context

摘要

@@Introduction Ecological integrity of a system is a precondition to sustainability ( Singh 2007).Rangelands that occupy large chunk of the geographical area in the Himalayan mountains have a key role to play towards imparting high degree of sustainability to an agroecosystem and thereby to the land-based livelihoods in the mountain areas.Ecological integrity of a system is ensured when there are ecological linkages between components of the system and,as a result,there is considerable flow of water/ moisture and nutrients within the system.
