The issues of water and food security are timely and important to the discussion of the future of sustainable development. Population and climate are major drivers, leading to regional water constraints that are emerging as critical in many places in the world. The ability of societies to deal with these threats is coming into question, whether the issue is the provision of safe drinking water, or of access of industries to water, the rapid depletion of groundwater by agriculture, limits to energy production and mineral extraction, or the impacts of degraded water bodies on ecosystems. What are the innovations that can address these challenges, and what are some examples of sustainable directions towards solution?
