In the analysis, valuation of non market variables, i.e, non market benefits and non market costs, were carried out in order to estimate the extended costs and benefits and the ecological capital of rubber. Net Present Value (NPV) and Benefit Cost Ratio (B/C Ratio) have been used as the yardstick to measure the environmental economic viability of rubber. The discounted cash flow analysis was carried out for 33 year life span of rubber using 5;, 15;and 30;discount rates. Evaluation was also done for two scenarios i.e, the production of Ribbed Smoked Sheet (RSS) and the production of crepe. The results reveal the economic as well as the environmental feasibility of this crop, which generated NPV of Rs. 278,200/- per hectare and B/C ratio of 2.9 per hectare at 15;discount rate for crepe rubber production. Latex prices and cost of cultivation of rubber were subjected to sensitivity analysis to ascertain the economic and the environmental viability of the crop under different conditions. The conclusion arrived at in this study is that, this plantation crop may be used for industrial purposes as well as for environmental conservation.
