1. ELD Working Group on Economic Valuation of Options and Outcomes Dr Pushpam Kumar, WG Leader Chief, Ecosystem Services Economics Unit of Division of Environmental Policy Implementation (DEPI) United Nations Environment Programme (UNEP) UNCCD 2 nd Scientific Conference

2. Objectives 1.Establish different scenarios of land degradation at the global scale 2.Identify range of interventions and response policies (technical, mechanical, biological measures, etc.) 3.Evaluate cost of action (Benefit from avoiding damage) 4.Evaluate cost of inaction (Cost due to damage)

3. Approaches Identify benefits of avoided degradation Multi Scale Assessment Mapping of benefits from ecosystem services Timeframe: Current (2013-14), 2015, 2025

4. Types and Extent of Land Degradation Types/degree of land degradation Region 1Region 2Region 3Region n LD1$1x$5x Land degradation 2 Land degradation 3 LD n

5. Representative Cost Data Options/interv entions Region 1Region 2Region 3Region n Option 1$4x$1 Option 2 Option 3 Option n

6. Data on Benefits (avoided degradation) Benefit gained (On site / off site) Region 1Region 2Region 3Region n e.g. Gain in productivity $1x$1.5x Option 2 Option 3 Option n

7. Trade-offs and synergies: Analysis of response options Option/ Intervention Agricultural Yield Carbon Sequestration Water Filtration Flood Mitigation Reforestation-+++ Modified cultivation technology ++++ etc

8. Next Action 1.Development of Database on Values 2.Synthesis of evidences (peer reviewed, semi reviewed values) 3.Relevant time period not beyond 2005 4.Team in place (Experts identified) 5.Resources??
