ABSTRACT
According to the 2012 UN World Water Development Report (WWDR), there will be a sharp growth in demand for water resources in the next two decades: food demand is predicted to increase by 50 percent and demand for energy, which includes hydropower, is predicted to increase by 60 percent (WWAP [2012]). Inasmuch as water is fungible, pressure from these various sectors is said to require an estimated additional 6 percent increase in water withdrawals (FAO [2012]). Faced with the prospect of an impending global water crisis, governments, water authorities, and academics are trying to find innovative ways of managing water resources.
