Integrated Catchment Management Developing Partnerships for a Sustainable Future

1. Integrated Catchment ManagementDeveloping Partnerships for a Sustainable Future William B. Bowden Landcare Research www.landcare.cri.nz

2. What is “integrated catchment management”? An approach which recognises the catchment or river basin as the appropriate organising unit for research on ecosystem processes for the purpose of managing natural resources in a context that includes social, economic and political considerations.

3. Why use an ICM approach?

4. The fundamental challengesof managing land/water resources • Understanding the consequences of resource uses distributed across land • Understanding the consequences of resource uses distributed over time

5. Spatial organisation of resource uses

6. The fundamental challengesof managing land/water resources • Understanding the consequences of resource uses distributed across land • Understanding the consequences of resource uses distributed over time

7. Temporal organisation of resource usesSingle impact Impact magnitude Time

8. Temporal organisation of resource usesCumulative impacts Threshold Impact magnitude Time

9. Temporal organisation of resource usesMixed impact Impact magnitude Time

10. The fundamental challengesof managing land/water resources • Understanding the consequences of resource uses distributed across land • Understanding the consequences of resource uses distributed over time Okay….so how to you do it?

11. What is the relationship between integrated catchment managementandan ecosystem approach toresource management?
