ArticleAssessment and value of ecosystem services of Mukogodo forest landscape, Kenya
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.In Kenya, land degradation is caused by a growing human population, poor land-use practices, and a lack of appreciation of the economic costs of degradation among other factors. One of the landscapes facing land degradation is the Mukogodo. There is empirical evidence that most environmental degradation is driven largely by a lack of appreciation of the economic values of ecosystem services provided by natural landscapes. The purpose of this study was to determine the economic value of the Mukogodo landscape. Data on forest use and benefits from the landscape were collected from 230 households using structured and semi-structured questionnaires and supplemented with Focus Group Discussions, Key Informant Interviews, and rapid market surveys of key forest products in urban townships. Carbon stocks assessment was undertaken from fifty-one (51) temporary sample plots established across six vegetation classes applying the National sampling framework procedures. Economic values of Ecosystem services were estimated using Market prices, Contingent valuation, Cost-based, and Benefit Transfer (BT) techniques. The total economic value (TEV) of the Mukogodo landscape was about KES 9.1billion /year (US$ 85million /year). Regulating and supporting services formed the bulk of TEV of about 50%, emphasizing the importance of intangible use values in the landscape sustainable management. This paper has highlighted the contribution of the Mukogodo landscape to the local economy. This information can influence the attitudes of stakeholders and increase commitments to the sustainable management of the landscape.

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.

ArticleForest natural resource management and non-timber forest products as nature-based solutions for climate adaptation, ecosystem restoration and poverty alleviation in Mali– a case study
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Climate change, nature loss and poverty are major intertwined crises that mutually reinforce each other. This is particularly true for smallholder farmers in Africa’s drylands: they are the hardest hit by the climate crisis, which contributes to the degradation of the land upon which their livelihoods depend. Further pushed into poverty, rural people are forced to resort to unsustainable land practices for survival, feeding the cycle of environmental degradation and climate change. Intertwined crises need integrated approaches, such as nature-based solutions (NbS) that protect natural ecosystems and address societal challenges. Tree Aid works in Africa’s drylands to unlock the potential of trees to tackle poverty and improve the environment. Here, we present a quantitative NbS case study looking at the impacts of the adoption of forest natural resource management (NRM) and increased production of non-timber forest products (NTFPs) among smallholder farmers in the Segou region in Mali between July 2017 and July 2020. This project was a partnership between Tree Aid, the UK funded Darwin Initiative and local partner Sahel Eco.Its socioeconomic impact was evaluated with focus group discussions, baseline and endline assessments using the Rural Household Multi-Indicator Survey (RHoMIS) (https://www.rhomis.org/). Ecosystem restoration impacts were assessed by ecological surveys and data from permanent monitoring plots.We demonstrate that NRM and NTFPs delivered positive outcomes for people (reduction of project population living below the poverty line), biodiversity (+20,404ha of land under improved management), and climate (improved climate resilience through better access to natural resources). This evidences the viability of high-quality NbS in Africa’s drylands and calls for greater long-term restoration investment and deployment in the region informed by and delivered through local communities and organisations.
