Agricultural impacts Richard Howitt and Elizabeth Pienaar 12. Energy impacts Robert Mendelsohn 13. Coastal impacts James Neumann and Daniel Hudgens 14. Conclusion Robert Mendelsohn and Joel B. Smith Models are used to estimate potential physical and biological impacts efficient adaptations and residual damages from climate change. The contributors cover a broad array of climate change impacts on affected market sectors (including water supply agriculture coastal resources timber and energy demand) as well as ecosystems and biodiversity. An integrated hydrologic agriculture model is developed to explore how the region would adapt to changes in water flows. Interactions between climate impacts and population and economic growth urbanization and technological change are also explored. For example the study examines how both climate change and projected land development affect the regions terrestrial ecosystems and biodiversity
