"Eliminating water shortages depends on a global attempt to raise water productivity similar to the effort launched a half-century ago to raise land productivity, an initiative that has nearly tripled the world grain yield per hectare." –Lester R. Brown, World Facing Huge New Challenge on Food Front in Plan B 3.0: Mobilizing to Save Civilization
"For years -- even decades -- Earth Policy Institute president and Grist contributor Lester Brown has issued Cassandra-like warnings about the global food system. His argument goes something like this: Global grain demand keeps rising, pushed up by population growth and the switch to more meat-heavy diets; but grain production can only rise so much, constrained by limited water and other resources. So, a food crisis is inevitable...Coming from a man who's been studying agricultural productivity since the 1960s, and who was in fact a booster of the original "Green Revolution" -- the push by U.S. policymakers and foundations to prod farmers in the global south to use "modern" agriculture technologies such as hybrid seeds, industrial fertilizers and pesticides, and heavy irrigation -- this is a significant statement," writes Tom Philpott, senior food and agriculture writer on Grist.org in a release titled 'The ‘food bubble’ is bursting, says Lester Brown, and biotech won’t save us.'
