The non-extractive values are mainly in watershedprotection and carbon, the latter having been estimated above. However, in highly unstable areas, some forest areas may ultimately be designated solely for watershedprotection. For other watershedprotection services, namely urban supply and irrigation, the information was scarcer. Existing data allowed quite a detailed analysis of watershedprotection benefits. There is some evidence, however, that increased watershedprotection will increase profits through greater baseflow only in watersheds with a unique mix of physio-graphic and climatic features. We do not claim to perform a comprehensive cost-benefit analysis of watershedprotection; instead we focus on the estimation of the benefits or values of watershed services. This picture is complicated by the increasing tendency to question the traditional belief that watershedprotection values provided by primary forest are unambiguously positive. They could also include the non-market, off-site values associated with watershedprotection, such as stream flow maintenance and prevention of river and inshore siltation. As a consequence, the establishment of large hydroelectric reservoirs in deforested watersheds often leads to proposals for curtailing agriculture and livestock production in favor of watershedprotection and reforestation. Ultimately, new forest management systems that integrate timber production, watershedprotection and other objectives will be required. To assist forest managers, improved methods are needed to evaluate watershedprotection benefits in specific sites and to assess the economic trade-offs between timber production and watershedprotection objectives. Such guidance seems necessary given the current reliance on partial analysis and outdated conventional wisdom of the benefits of watershedprotection in the humid tropics. The primary conservation goal was to provide greater protection against deforestation threats and to initiate reforestation and land conservation that enhances watershedprotection. Exploratory regression analysis to evaluate the impact of increased forest cover shows that physiographic and climatic factors strongly influence the likelihood of drought mitigation from watershedprotection activities. Pattanayak (forthcoming) presents a related example in which household collection costs for water from streams depend on objective indices of watershedprotection and in-stream water availability. Additional incentive mechanisms for promoting watershedprotection are thus justified as a means of moving land use towards more economically efficient land use alternatives. Increasingly, foresters participate in wildlife conservation planning and watershedprotection. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
