Summary

This book provides a detailed account of the fragile and marginal physical and socio-economic systems which make up the world's mountain regions. Discussing the direct and indirect impacts of human interference with ecosystems, it then turns to the social and economic consequences of such environmental change--both for the mountain environment itself and for the populations who depend on mountain resources for their economic sustenance.
