ArticleEcosystem service approach of valuing natural forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Ecosystem, through its structural and functional components, delivers goods and services to the functioning of ecosystem itself and ecosystem services to the human society. The present paper identifies ecosystem services and stimates economic value of natural forests through ecosystem services provided by Panchase Forest in the Central Mid-hills of Nepal. Transect walk, focus group discussion, key informant interview and expert consultation was made to identify ecosystem services. The economic value was estimated applying ‘total economic valuation’ framework considering both use and non-use values. Use values include consumptive, non-consumptive and indirect uses. Non-use values include option, existence, altruist and bequest values. Market price method was applied to estimate consumptive and indirect use values whereas, travel cost method was applied to estimate non-consumptive use values. Contingent valuation method was applied to estimate non-use values through ‘willingness to pay’. The Panchase Forest provides 17 types of ecosystem services including 6 provisioning, 6 regulating, 2 habitat and 3 cultural and amenity services. The total economic value of the ecosystem services provided by the forest was found to be USD 2.05 million per year. The contribution of consumptive use value, non-consumptive use value, indirect use value and non-use value was found to be 33%, 19%, 23% and 25%, respectively. The consumptive use value, which is recognized by national accounting system, has only one third contribution to total economic value of the forest. This results in the undervaluation of economic contribution of forests in national accounting system and thus in the country’s economic decisions. The present paper has suggested to revisit the current framework of national accounting system recognizing the value of forest ecosystem services in economic decisions.

ArticleTowards transformation of agricultural landscapes: Determination of agroforestry tree species producing beneficial ecosystem services to local farmers in Nigeria
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The aim of this study is to transform agricultural landscapes through incorporating tree species that produce ecosystem services beneficial to local farmers. To achieve this, the study assessed existing diversity of tree species producing ecosystem services in agricultural farmlands in selected local communities of southwest Nigeria. The information obtained will then be used to design strategy for intensification of agroforestry tree species for transformation of agricultural landscapes. Purposive sampling was employed in selecting 66 local farmers who has personal farmlands. Information on available tree species and their diversification on farmlands were obtained through inventory and field observation. Primary information obtained through questionnaire administration include ecosystem services provided by trees on the farmlands. A total of 38 forest tree species (24 families) were identified on the different farmlands. Provisioning services dominated the ecosystem services benefits obtained by the farmers and their households. The study has revealed the different ecosystem services provided by forest trees on farmlands. Meanwhile, most of the farmers prefer trees that meet their personal needs. This means for proper adoption of forest trees at local level in agroforestry system, such trees must be able to meet local demands by providing some of their basic needs. The basic needs range from food to medicines, energy, cultural benefits, among others. Meeting of such needs are sometimes location specifics, hence the needto carry out adequate survey of such needs for intended intervention strategy.

ArticleUsing choice experiments to estimate the simulated exchange value of species preservation services for ecosystem accounting
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.We present a choice experiment for the valuation of preservation services for threatened aquatic wild birds in the coast wetlands of the southwest of the Iberian Peninsula. We test the potential of stated preference methods to estimate non-market exchange values for ecosystem accounting. The experiment was administered to a sample of the adult population of Spain (n = 800) and Portugal (n = 179) in 2019. The program attributes were described as the variation in the number of aquatic wild bird species in each of the three threat categories of the red list of species plus a one-time increase in income taxes for the implementation of the program. The preferred model shows that passive consumers are willing to pay more to reduce a higher number of species in each category, but marginal willingness to pay (WTP) is substantially higher for “critically endangered” species. Based on this model, we estimate a marginal WTP-based simulated exchange value of €440 per person for a one-time payment (equivalent to €16.41 per year for 30 years), which would be paid by 34% of passive consumers. These estimates represent exchange values consistent with the valuation criteria of national accounts in contrast to the Hicksian surplus, which is 1.6 times higher in our application.
