Abstract: This paper is about the cost-benefit analysis of a specific soil andwater conservationmeasure, commonly termed as ‘exclosures’ in the case study area of this research, adopted in the Tigray region of northern Ethiopia. The analysis integrated available data on on-site and off-site effects of the conservation measure. Major benefit and cost
items related to this specific measure were identified, quantified, and valued. Direct market prices and variants
of indirect environmental valuation techniques (cost based and productivity change methods) were employed in valuing the benefit and cost items included in the analysis. Our results indicate that establishing exclosures in degrading marginal lands generate a large positive net present value (NPV) of ETB 5620 ha−1. However, putting productive agricultural land under exclosures yields a negative NPV even under some hypothetical scenarios of 50% rise in prices of forest products and a social discount rate halved from the base rate of 8%. Sensitivity analyses indicate that the net present value is quite volatile to changes in biomass production and the social discount rate. Thus, appropriate forestmanagement schemes have to be adopted in order to maximize sustainable biomass production. Furthermore, factors such as credit constraints that affect local people's time preference should be addressed to induce local people to discount the future at lower rate.
