Tight interconnections exist between water, energy, and food systems. As stresses on these
resource systems continue to increase, there is a growing need to better quantify and
understand the trade-offs associated with their future planning and management (Figure 1).
Water is used to produce hydropower and to cool thermal power plants. Groundwater is
impacted by hydraulic fracturing: the extraction of oil and gas carries the collateral danger of
contaminating neighbouring aquifers and affecting the supply of water for drinking . . .
