Book excerpt: Stanley Stevens brings new ecological and historical perspectives to his study of a subsistence society in ever-increasing contact with the outside world. The Sherpas of the Mount Everest region, famous for their mountaineering exploits, have frequently been depicted as victims of the world`s highest-altitude tourist boom. But have the Sherpas and their homeland been transformed by tourism? He is the first to analyze the complex interaction of local environmental knowledge, cultural beliefs, and socio-economic and political conditions in changing sherpas subsistence strategies, land use practices, and local resources management institutions. Claiming the High ground is must reading for all those interested peoples and concerned about the conservation of the earth`s high places.
