- 11. 11 What is Mainstreaming Ecosystem Services? Integrating or incorporating actions related to conservation and sustainable use of biodiversity into strategies relating to production sectors, such as agriculture, fisheries, forestry, tourism and mining Including biodiversity considerations in poverty reduction plans and national sustainable development plans
- 12. 12 Mainstreaming Ecosystem Services Requires an understanding and acceptance of the importance of a healthy environment to well- functioning production sectors Requires mechanisms (e.g. inter-agency taskforces; coordinating committees etc;), the will and ability to identify win-win situations Requires an extensive strategy of communication, education and public awareness
- 13. 13 Ecosystem Approach = Integrated Management Strategy The ecosystem approach is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. Thus, the application of the ecosystem approach helps to reach a balance of the three objectives of the CBD: conservation; sustainable use; and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources
- 15. 15 Principles of Ecosystem Approach (CBD) Principle 1: The objectives of management of land, water and living resources are a matter of societal choice Principle 2: Management should be decentralized to the lowest appropriate level (subsidiarity) Principle 3: Ecosystem managers should consider the external effects (actual or potential) of their activities on adjacent and other ecosystems.
- 16. 16 Principles of Ecosystem Approach Principle 4: Recognizing potential gains from management, there is usually a need to understand and manage the ecosystem in an economic context. Any such ecosystem-management programme should: a) Reduce those market distortions that adversely affect biological diversity; b) Align incentives to promote biodiversity conservation and sustainable use; c) Internalize costs and benefits in the given ecosystem to the extent feasible.
- 17. 17 Principles of Ecosystem Approach Principle 5: Conservation of ecosystem structure and functioning, in order to maintain ecosystem services, should be a priority target of the ecosystem approach Principle 6: Ecosystems must be managed within the limits of their functioning Principle 7: The ecosystem approach should be undertaken at the appropriate spatial and temporal scales
- 18. 18 Principles of Ecosystem Approach Principle 8: Recognizing the varying temporal scales and lag- effects that characterize ecosystem processes, objectives for ecosystem management should be set for the long term Principle 9: Management must recognize that change is inevitable Principle 10: The ecosystem approach should seek the appropriate balance between, and integration of, conservation and use of biological diversity
- 19. 19 Principles of Ecosystem Approach Principle 11: The ecosystem approach should consider all forms of relevant information, including scientific and indigenous and local knowledge, innovations and practices Principle 12: The ecosystem approach should involve all relevant sectors of society and scientific disciplines

- 24. 24 Operational Objectives for Ecosystem Approach Management (1) Develop broad Stakeholder-Based Governance system (2) Conserve essential Parts of the ecosystem (3) Conserve essential ecosystem Processes Question, if (2) is done well, is (3) necessary?
- 25. 25 Basic Steps Towards Developing Mechanisms for Conserving Ecosystem Services The process can be done in an iterative way
- 26. 26 Operational Guidance for Mainstreaming Ecosystems Services 1. Focus on the functional relationships and processes within ecosystems 2. Enhance benefit-sharing 3. Use adaptive management practices 4. Carry out management actions at the scale appropriate for the issue being addressed, with decentralization to lowest level, as appropriate 5. Ensure inter-sectoral cooperation
