1. People in Ecosystems/Watershed Integration (PEWI): A dynamic land-use and ecosystem service tradeoffs assessment tool

2. Why PEWI? How agriculture can produce outcomes that society desires How we can learn – Complex social-ecological relationships – Ecosystem service tradeoffs How we can facilitate urban-rural dialogue

3. An analogy The analogy of a sandbox is a great way to think about PEWI Why a sandbox?

4. Friends and a sandbox

5. The right tools and a design

6. The finished product…until

7. Create something new

8. What if there were a virtual “sandbox” to explore humans, land use, and ecosystem service in a watershed?

9. PEWI is that sandbox Fun, simple, and accurate Explore land uses and ecosystem services without technical expertise or the costs of experimenting in the real world

10. Introduce PEWI Models how changes in land use and management result in tradeoffs in the levels of ecosystem services outcomes in a fictional Iowa agricultural watershed

11. Introduce PEWI Models how changes in land use and management result in tradeoffs in the levels of ecosystem services outcomes in a fictional Iowa agricultural watershed 4 concepts: 1.Land use and management 2.Watershed 3.Tradeoffs 4.Ecosystem Services

12. 1. Land uses and management

13. 2. What is a watershed? When water hits land, runoff drains to a stream, lake, or larger waterway. A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place.

14. 3. What are ecosystem services? Ecosystem services are “the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfil human life” (Daily, 1997). Ecosystem services are “the benefits people obtain from ecosystems. These include provisioning services such as food and water; regulating services such as flood and disease control; cultural services such as spiritual, recreational, and cultural benefits; and supporting services, such as nutrient cycling, that maintain the conditions for life on Earth” (UNEP, Millennium Assessment Reports).
