Ecosystem goods and services 101 The EGS review and comparative - PowerPoint PPT Presentation

• Introductory comments re the context of the workshop • Ecosystem goods and services 101 • The EGS review and comparative analysis method • Identification of the EGS related to community livelihoods / societal resilience • EGS review and comparative analysis

Nature plays a substantial role in providing a wide variety of vital life supporting goods and services. Conversely, where nature is degraded or replaced, not only are these goods and services lost, but there are consequences which inevitably manifest in costs to society. We need to understand these trade-offs so that we can make informed decisions regarding our options.

For poor people, the greatest gains in well-being will occur through more equitable and secure access to ecosystem services. In the long run, the rich can contribute greatly to human well-being by reducing their substantial impacts on ecosystems and by facilitating greater access to ecosystem services by the poor (MEA, 2005). We just need to be careful when labelling people “poor” and “rich”.

Applying ecosystem services thinking to the assessment of land cover integrity in relation to catchment services 3 the land cover type has the maximum ability to deliver ecosystem services the land cover type has a moderately reduced ability to deliver ecosystem 2 services the land cover type has a significantly reduced ability to deliver ecosystem 1 services the ability of the land cover type to deliver ecosystem services has been lost but 0 not to the extent that dis-services are produced and delivered -1 a low level of dis-services are produced and delivered by the land cover type a moderate level of dis-services are produced and delivered by the land cover -2 type -3 a high level of dis-services are produced and delivered by the land cover type
