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. Key points ICM as a research approach ICM as a management partnership The strategic context for ICM The Motueka Catchment initiative The Waitakere City initiative

4. Why use an ICM approach?

5. The fundamental challenges of managing land/water resources Understanding the consequences of resource uses distributed across land Understanding the consequences of resource uses distributed over time

6. Spatial organisation of resource uses

7. The fundamental challenges of managing land/water resources Understanding the consequences of resource uses distributed across land Understanding the consequences of resource uses distributed over time

8. Time Impact magnitude Temporal organisation of resource uses Single impact

9. Time Impact magnitude Temporal organisation of resource uses Cumulative impacts Threshold

10. Time Impact magnitude Temporal organisation of resource uses Mixed impact

11. The fundamental challenges of 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?

12. What is the relationship between integrated catchment management and an ecosystem approach to resource management?
