Session 2b: Ecosystem condition, Regulating ecosystem services Session 2b on ecosystem condition built on the previous ecosystem extent session. The measures of ecosystem extent together with ecosystem condition provide the basis to assess ecosystem assets and their capacity to generate ecosystem services. Therefore, the compilation of ecosystem condition account requires the selection of the appropriate indicators to measure the key ecosystem characteristics, e.g. vegetation, water resources, soil, carbon, biodiversity. During this session, details on selected indicators and methods to assess ecosystem condition and regulating ecosystem services were presented. Session 2c: Provisioning ecosystem services Session 2c covered provisioning ecosystem services, including detailed CICES classification of provisioning services, identification and assessment of provisioning ecosystem services in the Kyzyl Unkur case study on walnut forests and the compilation of ecosystem service supply and use tables. It was highlighted that the supply and use tables are one of the most important aspects of SEEA as they present the contribution of ecosystems to the products that are already marketed and consumed, and are already captured by the System of National Accounts. The participants were engaged in a conceptual exercise on the value chain of walnut provision to understand the flow of ecosystem service into benefits and products, including the discussion on economic units included in the value chain. Subsequently, the participants practiced the compilation of ecosystem service supply and use tables. On the basis of the data provided by the NSC and SAEPF, the preliminary supply and use tables were presented and discussed.
