In this video, leading freshwater expert Steve Gorelick discusses changes in human and natural systems and how these can drive threats to freshwater resources in the 21st century.
An overarching challenge will be to create freshwater systems that can sustain human wellbeing and natural ecosystems in the presence of rapid environmental and socioeconomic change. Solutions are likely to rely on modern engineering and information technologies, combined with effective planning, policies and institutions.
Steve Gorelick is the Cyrus F. Tolman Professor in the Department of Environmental Earth System Science and a Senior Fellow in the Woods Institute for the Environment at Stanford University in California. This presentation was given to the National Centre for Groundwater Research and Training, at Flinders University in South Australia, on 14 August 2012.
Correction: Please note that it takes 1 liter of water to grow/produce 1 food calorie, not 3000 liters (as is mistakenly mentioned), which is the daily water total, not the per calorie total.
