This study was conducted to make a benefit-cost analysis of the Integrated Social Forestry (ISF) Project in Tublay, Benguet [Philippines], with on-site environmental effect considered. Using the benefit and cost criterion, the ISF project comprising 44.51 hectares with about six hectares planted to cabbage, carrot, potato, and chayote, the rest of the area planted to alnus and coffee trees, and operated by 20 households proved to be highly profitable. Estimated benefit cost ratio was calculated to be 4.0. This implied that for every one peso invested three pesos was realized. Using the Net Present Value as a criterion, the project further proved to be highly profitable. The NPV showed a high positive value of P5,293,926.61. The productivity loss prevented was calculated in terms of macro-elements (N, P, K) carried by the soil loss prevented as a result of the project. It was estimated that an amount of P4,958.48 of fertilizer equivalents of N (2000 kgs), P (264 kgs), and K (408 kgs) per hectare was prevented from being lost. Considering the total project area of 44.51 hectares, the on-site environmental benefit of P220,701.94 could be attributed to the project. While the ISF project in Tublay has not achieved all its objectives as specified in the plan, it succeeded in the following areas: a) increase in off-farm income was brought about by the employment of the participants to work as casuals in the nursery section of the ISF project; b) indiscriminate tree cutting was reduced with the introduction of alnus tree which could ensure a steady supply of fuel-wood, if managed properly; and c) the coffee trees given to the participants had a positive impact on the participants' farm income.
