Fifteen years ago, if you asked Asit Biswas if he believed there was a global water crisis, he would have answered “Yes.” Now, however, the Stockholm Prize winning water researcher says he believes the water crisis is indeed a myth. Biswas made his statement in a lecture at the 2009 Nobel Conference held at Gustavus Adolphus College last October.
While there are notable books on the subject of global water scarcity, including those authored by fellow speaker Peter Gleick, Asit pointed out that he doesn’t see a world water crisis caused by physical water scarcity, but by water management – or rather, a lack of water management.
Asit believes that there is indeed enough water to go around as long as people manage their water better. In his talk he highlighted the fact that 70% of the world’s water is used for agriculture - therefore, inefficiencies in the food chain are also a major drain on water resources. According to Asit, food waste is extremely high, with the USDA reporting that 27% of food in the U.S. goes to waste, while in India 50% of fruits and vegetables and 33% of all cereal grains never make it to the consumer. Asit noted getting food to the people and minimizing waste is one way to increase food availability without the need for additional water. His idea extends to the domestic side as well, where water leaking from distribution pipes is commonplace around the world.
Water efficiency and management is a cornerstone to many of Lux Research’s water reports, most notably the recent reports published on agriculture and water IT. In the Lux Research report entitled “Malthus Returns: Solving the Unsustainable Agricultural Water Demand Conundrum” (client registration required), we highlight the fact that it’s impossible to recapture an appreciable amount of water evaporating from agricultural regions. The only option left to agriculture is to increase water efficiency through technologies such as drip irrigation provided by Netafim and John Deere Irrigation; smart irrigation systems provided by Hydropoint and PureSense; and practices such as increasing crop yields and reducing the volume of water needed.
Improving water efficiency on the domestic side is addressed in the Lux Research report “Ranking Water Information Technologies on the Lux Innovation Grid” (client registration required). In the report, we highlight the fact that utilities, industries, consumers, and governments need to manage water more efficiently, and a basic solution to the water management problem is obtaining better information about water usage through information technologies provided by companies such as Derceto and Itron to minimize unaccounted-for water, reduce water consumption, minimize water pollution, and reduce energy consumption.
There are no fundamental issues that contribute solely to the water crisis. Water is indeed scarce in certain areas of the world where the population density is high, and it’s true that water efficiency and management are in dire need of improvement, as is the aging infrastructure. Improving water efficiency is an integral component to solving the water crisis, but there is also a need for increased funding of public water supplies as well as more investments in the hydrocosm to continue development of innovative water and energy-efficient treatment technologies. Finally, there’s a need for change in the mindset of how water is used and consumed. Not until all of these criteria are met will we truly see an end to the water crisis.
