Anthropogenic activities on watershed levels has been the cause of mounting developmental pressures on natural resources and an environmental impact assessment using remote sensing for the period 1988-1992 was performed. It was possible to infer both positive and negative impacts for a basic resource unit like a watershed in an ecologically fragile Himalayan region. The significant parameters were derived and their inter - relationships discussed in this paper which should help in choosing the development priorities and micro - level planning for an environmentally sound and sustainable development of such regions.
