Ecosystem Services Review for Impact Assessment

Transcription

1 Ecosystem Services Review for Impact Assessment Road-test draft ACES Conference, 10 December 2012 F. Landsberg, M. Stickler, N. Henninger, J. Treweek and O. Venn

2 Ecosystem Services Provisioning Regulating Cultural 2012 IFC PS 6: - maintain the benefits from ecosystem services Supporting - identify ( ) those services on which the project is directly dependent for its operations

3 Overview ESR for IA: overview ESR for IA: implementation steps Preliminary findings from retrospective road-tests Next steps

4 ESR for IA: Objectives Impact: Enhance or at least maintain the well-being people derive from impacted ecosystems at baseline levels Dependence: Enhance or at least maintain project performance over the life of the project

5 ESR for IA: Framework PROJECT ENVIRONMENTAL IMPACTS (from EIA) PROJECT PERFORMANCE FROM ECOSYSTEM SERVICES DRIVERS OF ECOSYSTEM CHANGE EXTERNAL TO PROJECT ECOSYSTEM CHANGES CHANGES IN ECOSYSTEM SERVICES PROJECT SOCIAL IMPACTS (from SIA) Conducted during traditional ESIA Conducted with the ESR for IA Conducted during ESR for IA impact assessment Conducted during ESR for IA dependence assessment PROJECT SOCIAL IMPACTS FROM ECOSYSTEM SERVICES

6 ESR for IA: Implementation steps Scoping stage Step 1 Identify relevant ecosystem services Output: ES-inclusive ESIA ToR Step 2 Prioritize relevant ecosystem services Impact analysis stage Mitigation stage Step 3 Step 4 Step 5 Step 6 Define the scope of the assessment Establish the baseline for priority services Assess project impacts and dependence on priority services Output: ES-inclusive ESIA report Mitigate impacts and manage dependence on priority services Output: ES-inclusive E & S Management Plans

7 Overview ESR for IA: overview ESR for IA: implementation steps Preliminary findings from retrospective road-tests Next steps

8 Step 1: Identify relevant ecosystem services Impact Impacted ecosystems and associated services Project Dependence Impacted beneficiaries Operational inputs and processes Ecosystem services the project impacts Ecosystem services on which the project depends

9 Step 2: Prioritize relevant ecosystem services Impact Could the project s impacts on this ecosystem service lead to impacts on well-being? Yes or? Dependence Could changes in this ecosystem service lead to changes in project performance? Yes or? Is this ecosystem service a major contributor to beneficiaries well-being? Yes or? Is there a viable alternative to this ecosystem service? Is this ecosystem service a major contributor to project performance? Yes Is there a viable alternative to this ecosystem service? No or? Priority ecosystem services No or?

10 Impact Prioritization Tool

11 Step 3: Define the scope of the assessment Delineate the ecosystem service project area It includes: ecosystems supplying priority services locations where beneficiaries and project access priority services Project Impact area Dependence area

12 Step 3: Define the scope of the assessment (ctd) Identification of indicators of project impact and dependence on priority services: - Priority service supply: ecological indicator that can be linked to beneficiaries well-being/ project performance - Beneficiaries well-being/ project performance: socioeconomic indicator that reflects the contribution of the priority service to well-being/ performance Dependence Impact Priority service Beneficiaries well-being supply Priority service supply Project performance Poverty rate among downstream Maintenance costs for Turbidity of water in canals farmers Kg of crop/ha/ year pumps Rate of malnutrition among children of downstream farmers

13 Step 4: Establish the baseline for priority services Indicator of priority service supply: based on ecological data and models Indicator of beneficiaries well-being: based on socioeconomic data and stakeholder engagement Indicator of project performance: based on project description and discussion with project developers

14 Step 5: Assess project impacts and dependence on priority services Impact Predict supply of priority services as a result of project environmental impacts Predict beneficiaries well-being based on expected supply Dependence Predict supply of priority services as a result of drivers of ecosystem change external to the project and the project environmental impacts Predict project performance based on expected supply

15 Step 6: Mitigate impacts on priority services Gain in well-being from positive project impacts on priority services Loss of well-being from negative impacts on priority services Enhance positive project impacts on priority services Compensate for loss in well-being due to negative project impacts Rectify negative impacts on priority services Minimize negative impacts on priority services Avoid negative impacts on priority services Baseline well-being

16 Step 6: Manage dependence on priority services Supply of priority service required to achieve planned performance Changes in project design Loss in performance before management of project dependence Loss in performance after management of project dependence Increase supply of priority services Expected supply of priority service

17 Overview ESR for IA: overview ESR for IA: implementation steps Preliminary findings from retrospective road-tests Next steps

18 ESR for IA: preliminary feedback from retrospective road-tests Integrate assessment (e.g., unveil social impacts as a result of environmental impacts, unveil social impacts in the absence of SIA) Level the ground among social impacts (e.g., impact on livelihood from impact on provisioning services and impact on social capital from impact on cultural services) Unveil dependence on environment for continued performance Systematically review impacts and support the production of intermediary outputs (e.g., prioritization tool)

19 Overview ESR for IA: overview ESR for IA: implementation steps Preliminary findings from retrospective road-tests Next steps

20 ESR for IA: next steps Finish retrospective road-tests Conduct on-going road-tests Continuous improvement of ESR for IA text and tools Now December 2012 March 2013 May 2013 December 2013 Publish road-test version 2-day IAIA training Publish final version
