Abstract:
The research entailed a comparative study of climate change‐water vulnerability and adaptation in two urbanizing watersheds. The presentation underlines multiple levels of complexity where the approach of blindly applying historical rainfall‐runoff relationships to predict future water supply are no longer valid. With climate change, multiple scales of vulnerability need also be factored in: climate variability occurs at the basin scale, whereas vulnerability is experienced at the household scale. As well, different areas of the watershed are vulnerable to different supply variability pathways. A new approach to planning for climate vulnerability will encompass multiple stressors.
