In this TED talk David Sedlak explores options that can be used to fend off drought in cities. The last century saw massive developments that treated water in a very unsustainable way (from dams to pathetic water policies). This century we will have to correct the mistakes of the past and focus on changing how we approach water as an ecological system.
As the world’s climate patterns continue to shift unpredictably, places where drinking water was once abundant may soon find reservoirs dry and groundwater aquifers depleted. In this talk, civil and environmental engineer David Sedlak shares four practical solutions to the ongoing urban water crisis. His goal: to shift our water supply towards new, local sources of water and create a system that is capable of withstanding any of the challenges climate change may throw at us in the coming years.
