According to the World Economic Forum’s Global Risks 2013 report, the water supply crisis is ranked as a top-five risk, in terms of both its likelihood to happen and its impact. With global freshwater demand projected to exceed current supply by over 40% by 2030, increasing competition and stress on water poses a significant risk and impact on food, energy and industrial and human security around the world, including on close to 4 billion people living in areas where the demand for water will far exceed available supplies. While population grew fourfold in the 20th century, demand for water grew by a factor of nine. This situation will create significant economic and political challenges. Water Security: The Water-Food-Energy-Climate Nexus, published by the World Economic Forum Water Initiative, states that in Asia, for example, agriculture currently uses 70% of annual global freshwater withdrawals and up to 90% in some parts of the region. Governments across Asia will need on average 65% more freshwater for their industry and energy sectors by 2030 to meet national growth aspirations.
