In many parts of the world, there are simply no more conventional freshwater resources available to meet growing demand.The only way to address this challenge is by radically rethinking water-resource planning and management in a way that emphasizes the creative exploitation of unconventional water sources.There is a large and growing number of unconventional sources of fresh water with massive potential, beginning with desalinated seawater or highly brackish groundwater.Already, there are 18,000 desalination facilities in more than 100 countries producing roughly 32 billion cubic meters of fresh water – about one-third of the volume passing over Niagara Falls annually.Recent studies show that, though the cost of irrigation with desalinated water remains higher than with conventional fresh water, it is declining.Fog harvesting today costs $1-3 per cubic meter of water.Finally, local institutions, nongovernmental organizations, and local communities must be mobilized – for example, through public campaigns showcasing the benefits of harnessing the potential of unconventional water resources.If governments do not embrace unconventional water resources, achieving that goal will be as difficult as getting water from a stone – and the consequences for water-scarce regions will be dire.
