The chapter examines the problem of choice of land use, energy input and technology that ensures economic viability and ecological sustainability in the Himalayan mountains. As the nature of the problem depends upon the local characteristics of the ecosystem, we propose to develop a model at the watershed level. This work develops a quantitative optimisation framework of net revenue maximisation using linear programming for structuring and articulating the problem of choice. The constraint of water availability has been taken into account to show how it drives the choice of technology and land use. The aims are to identify cost effective technologies, optimal land-use patterns and input combinations and to prescribe policies for adopting these technologies for rural situations with similar eco-regional and agro-climatic conditions.
