This paper describes the application of WaterWorld (<a href="www.policysupport.org/waterworld"target="_blank">www.policysupport.org/waterworld</a>) to the Peruvian Amazon, an area that is increasingly under pressure from deforestation and water pollution as a result of population growth, rural-to-urban migration and oil and gas extraction, potentially impacting both water quantity and water quality. By applying single and combined plausible scenarios of climate change, deforestation around existing and planned roads, population growth and rural–urban migration, mining and oil and gas exploitation, we explore the potential <i>combined</i> impacts of these multiple changes on water resources in the Peruvian Amazon.
