The Stockholm Statement to the 2012 United Nations Conference on Sustainable Development in Rio de Janeiro (Rio+20 Summit)

Water is the bloodstream of the green economy. Water, energy, and food are interlinked and interdependent; securing them is central to alleviating poverty and to creating a climate resilient and robust green economy. Population growth, expanding cities and accelerating economic activity increase the demand for energy and food and create unsustainable pressure on our water and land resources. By 2030, in a business as usual scenario, humanity’s demand for water could outstrip supply by as much as 40 per cent. This would place water, energy and food security at risk, increase public health costs, constrain economic development, lead to social and geopolitical tensions and cause lasting environmental damage.
