While many of today’s rivers, lakes and groundwater reservoirs continue to be overexploited, a new report launched today by leading scientists at the United Nations Commission on Sustainable Development warns that unless steps are taken to improve the way water is managed, twice the world’s current water consumption may be needed by 2050 to feed a global population of some 9 billion.
The scientists from the Stockholm International Water Institute (SIWI), International Food Policy Research Institute (IFPRI), World Conservation Union (IUCN) and International Water Management Institute (IWMI) said that the ambitious international commitment to halve the number of people facing hunger have missed a fundamental question: where is the water needed to grow the food to feed future generations properly?
The report, “Let It Reign: The New Water Paradigm for Global Food Security” points out that feeding the world is in many ways a daunting water challenge.
