Assessing the economic and ecosystem services contribution of forests: issues in modelling, and an illustration. (Special Issue: The Indian forest sector - current trends and future challenges.)

摘要

This paper aims to develop a methodology for valuing forest ecosystem services. It reviews alternative approaches to modelling the forestry sector's contribution to well-being. It subsequently extends existing techniques of cost-benefit analysis to the forestry sector and illustrates the application of the methodology through a case study of the state of Himachal Pradesh in India. The extended methodology captures variations that occur because of ecological aspects of forests, sustainability concerns regarding extraction from forests and aggregation issues in valuing ecosystem services. It also incorporates concerns about biodiversity valuation, particularly in protected areas. The paper highlights the importance of recognizing local variations in forest values, adopting a multi-disciplinary approach to valuation and the relevance of using more than one policy instrument for managing forest ecosystems.
