Water security is a growing global concern as the world faces a water crisis even greater than the financial crisis. Securing safe and plentiful water for all is one of the most challenging issues. A water secure world faces interconnected risks including water scarcity, food price volatility, extreme weather, and migration. To achieve water security will require new governance approaches that leverage change across economic, social, and environmental areas. It will also need strengthened institutions, innovative financial instruments, skills development, information sharing, and a focus on adapting to change.
