“…While Nyambene recorded the highest watershed protection value at about 58%, carbon sequestration at 26% of the total (Table 9) followed it. The study results were higher compared to a study in Taiwan that assessed forest ecosystem regulatory services at NT$400,976 (US$12976.57) per hectare per year (Lin et al, 2021). Equally, higher compared to a study in East Mau, valued at KES 641741.71 (US$5997.32) per hectare per year (Langat et al, 2019) and with the Nabanhe-Mangao and Mengla-Shangyong Corridor estimated at US$12947.71 and US$389248.33 ha −1 •year −1 , respectively (Xi, 2009).…”

Evidence of increased valuation of ecosystem services (ES) globally is significant. However, most of these studies focus on marketed subsets of ES at national and international levels. Ecosystems differ in spatial scale, biophysical and ecological structure, and functionality. This requires conducting studies at the local level to understand how, for example, the watershed ecosystem contributes to humanity locally and nationally. This study focuses on selected regulatory ecosystem services (RES) in Kenya's catchment area ecosystems (Elgeyo and Nyambene). Field-based sampling and Landsat imagery with secondary information were used to generate biophysical and ecological data. The study used market price-based, cost-based, and unit transfer methods for RES valuation. The study estimates the total value of the six selected regulatory ecosystem services (RES) at KES 41.4 billion (US$386.7 million) and KES 14.73 billion (US$137.71 million) for Elgeyo and Nyambene, respectively. This equates to KES 1.64 million (US$15,331.19) and KES 2.72 million (US$25,375) per hectare per year. Extrapolating the study estimates to the national level, the country's regulatory ecosystem services would range from US$18.4 billion to US$30.45 billion annually. This equates to between 16.7% and 27.7% of Kenya's GDP in 2021, underscoring the importance of watersheds to the national economy.

There is evidence of increased valuation of ecosystem services (ES) globally, however most of these studies tend to focus on marketed subsets of ES at national and international levels. Ecosystems differ in spatial scale, biophysical and ecological structure and functionality. This requires conducting studies at the local level to understand how, for example, the watershed ecosystem contributes to humanity both locally and nationally. This study focuses on selected regulatory ecosystem services (RES) in two catchment area ecosystems (Elgeyo and Nyambene) in Kenya. Both field-based sampling and Landsat imagery with secondary information were used to generate biophysical and ecological data. Market price-based, cost-based and unit transfer methods were used for the valuation. Aggregated economic values for the selected RES were estimated at KES 37.4 billion (US$349.6 million) and KES 14 billion (US$131.3 million) for Elgeyo and Nyambene respectively. This equates to KES 1.5 million (US$13,848.48) and KES 2.6 million (US$24,187.44) per hectare per year. At the national level, the value of regulatory ecosystem services would range from US$16.6 billion to US$29.03 billion. This equates to between 15% and 26% of Kenya’s GDP in 2021, underscoring the importance of watersheds to the national economy.

“…Most of the mountain and steep slope areas in the LRW are covered with forests that provide ecosystem services [31][32][33], based on long-term zoning laws and regulatory policies [34]. The land on the hillside in the LRW is classified into "land suitable for agriculture", "grazing land", "land suitable for forestry", and "land suitable for conservation".…”

“…The steep slopes in the hillside and high mountain areas are covered with forests in Taiwan [30,31], except for altitudes above the upper limit of the forest, where they are no longer present. Mountain forests could provide valuable ecosystem services [32,33]. However, the hillside regions are vulnerable to natural hazards, such as flash floods and landslides, and the availability of arable land is limited.…”

In the current fraught relationship between nature and human society, land conservation and utilization have spawned intensive conflicts that require mediation. The present study explores this issue of coordination between nature and society in a fragile watershed located in northeastern Taiwan: the Lanyang River Watershed. Land zoning in this area has been historically classified and legally implemented, and additional development is constrained by an application review process. Currently, additional land utilization is still in demand in sensitive areas of this watershed, such as for mining and tilling. Due to the geographically, geologically, and climatically fragile characteristics of the watershed, the hillside residents have benefited from the conservation of nature with comprehensive ecosystem services but are at the forefront of the loss of life and property caused by forest ecosystem degradation. They are one of the key local resource users and main stakeholders. Applying the contingent valuation method to survey the hillside residents, the present study assessed the economic value they receive from the comprehensive ecosystem services offered by the natural forest ecosystems. Their opinions are explored using a survey on their awareness of ecosystem damage, their opinions on damage compensation, and on the feasible compensation channels for damage. As the study results ascertained the high value of the comprehensive ecosystem services continuously delivered by the conserved forest ecosystem, the study affirmed that conservation in the area classified and zoned as sensitive is an economic beneficial policy. With a high regard for ecosystem services and awareness of the impact of degradation and of the general agreement for the feasibility of channels of damage compensation, the continuity of conservation for these comprehensive ecosystem services is the preferred strategy for the local hillside residents. To emphasize this further, the opinions of the local community at the intersection of nature and society, where there is a delineated land zoning framework, strongly favor conservation over intensive resource exploitation and agricultural expansion, making further development an unfavorable strategy.
