"Farm forestry is an important component of social forestry programmes that are now underway in India. Economics of farm forestry varies from region to region and from farm to farm within a region depending upon a number of factors. This paper explores the economics of farm forestry in a tribal village in Gujarat. Net Present value, Benefit-cost Ratio, and Financial Internal Rate of Return are used as indicators of financial viability of farm forestry. Farm forestry was found to be financially viable and ecologically sound use of marginal (degraded) land. It transformed the entire village economy from a backward one to a prosperous one and the landscape from desolate to green."
