  1. Valuation of ecosystem services in the SEEAProgress Report Glenn-Marie Lange The World Bank

  2. Major issues Concepts of value: Economic welfare vs market price In principle, valuation can provide marginal values comparable to market prices.  review of empirical studies Can markets/financial payments for ecosystem services provide missing values  Empirical studies about specific services, but no overview of the empirical literature has been done

  3. Major issues Public goods/biodiversity/transboundary ecosystems • work on economic approach to biodiversity in the context of climate change • Co-benefits of CC mitigation measures, REDD Where are methods well established and data available? • Human health impacts, particularly air pollution, but policy relies mainly on CV, VOSL not COI • Soil degradation—very site-specific

  4. Next steps Prepare overview paper on the issues over the summer Paper has been reviewed and comments sent to author for revision Workshop? Within the WB—collaboration with PREM VPU to introduce wealth/ANS/net aggregates on a systematic basis Ecosystem valuation & accounting, a global partnership TEEB, IPBES, Natural Capital Project, PEI, etc. If this is funded, it will be possible to address some of the issues raised
