Summary: Ecosystem services are defined as the benefits people obtain from ecosystems. This concept has received much attention in the last years. Ecosystem processes and components providing these services are affected by human influence. Quantitative and qualitative assessment data could be used to incorporate the ecosystem services in the decision-making process, using remote sensing data and GIS to provide a more general methodology to valuate the capacity of provision of ecosystem services in different landscapes.

The Chon-Aksuu is the largest river on the North shore of the Issyk-Kul Lake, Kyrgyz Republic. It is a popular place for tourists. Increasing human activity pressure as agriculture and tourism leads to the degradation of certain ecosystems ヨ mainly pastures and forests ヨ thus impacting the water resources of the river basin generally and the river flow specifically. There is a necessity of sustainable water management in the region. Local communities together with CAREC projects are working on implementation of effective Payment for Ecosystem Services scheme in the Chon-Aksuu River basin. This scheme will be supplemented through a Reducing Emissions from Deforestation and Degradation (REDD) mechanism to ensure a better protection of the Chon-Aksuu River watershed, forests and pastures. These new practices will be implemented taking into consideration the assessments of impacts of practicesメ changes on different ecosystems as rivers, forests or pastures. The main objective of this study is application of spatial modeling techniques of Ecosystem Services on the landscape level to provide a comprehensive assessment strategy. Capacity to provide ecosystem services in ecosystems is estimated using assessment matrix. Outcomes of the study are descriptive tables and maps which illustrate the potential of Chon-Aksuu river watershed to provide ecosystem services.
