Changes in the ecosystem services provided by forests and their economic valuation: a review
| Resumo: | In this chapter we discuss the trends in forest change and the associated drivers, the economic value of forests, the principles and challenges in evaluating the economic value of forests, and the role of valuation in informing decision- making. We address current major forest conservation initiatives at different scales and the mechanisms involved, whether supported by economic valuation or not. Today, 30 % of the world’s forests are designated for productive functions, 24 % for multiple uses, 11.5 % for biodiversity conservation, 8.2 % for protective functions, and 3.7 % for social functions. The remaining 22.6 % are designated for other uses or remain unclassifi ed. Global trends indicate that although the area of intensively managed forest continues to expand, the global extent of conservation and protec-tive forests is also increasing as a result of political efforts to preserve and restore the ecological functions of forests. Forest management practices are potentially bet-ter supported by extended cost–benefi t analyses that require an economic valuation of the whole array of benefi ts, whether market or non-market, provided by forests. Although we acknowledge other values and decision-making and support tools, the focus of the chapter is on the economic valuation approach. Our review in this chapter was guided by the goal of updating previous reviews of these topics. We have provided additional evidence that forests contribute to human well-being in many ways, and use the concept of ecosystem services as a building block to better understand, frame, and assess the economic benefits we derive from well-functioning forests. |
