An article in The Washington Post describes studies predicting the effects of global warming on agriculture, in the 2080s:
Several recent analyses have concluded that the higher temperatures expected in coming years — along with salt seepage into groundwater as sea levels rise and anticipated increases in flooding and droughts — will disproportionately affect agriculture in the planet’s lower latitudes, where most of the world’s poor live.
India could experience a 40% decline in agricultural productivity as “record heat waves bake its wheat-growing region, placing hundreds of millions of people at the brink of chronic hunger.”
Africa … could experience agricultural downturns of 30%, forcing farmers to abandon traditional crops in favor of more heat-resistant and flood-tolerant ones, such as rice.” Senegal and war-torn Sudan could have a “complete agricultural collapse.”
Scenarios like these — and the recognition that even less-affected countries such as the United States will experience significant regional shifts in growing seasons, forcing new and sometimes disruptive changes in crop choices — are providing the impetus for a new “green revolution.” It is aimed not simply at boosting production, as the first revolution did with fertilizers, but at creating crops that can handle the heat, suck up the salt, not desiccate in a drought and even grow swimmingly while submerged.
Fortunately, research on the new crops is underway, but it’s a race against time.

Brazilian food companies recently made two cross-border acquisitions: JBS (Latin America’s largest beef processor) bought Swift & Co.; and Perdigão (a leading Brazilian food company) bought Plusfood Groep BV in Europe. “While only two data points, we wonder if this foreshadows additional cross-border acquisitions by Brazilian companies in the increasingly global food industry.” — GE Commercial Finance industry newsletter
Sixty percent of Americans are pessimistic about the state of the environment and want prompt action taken to improve its health, according to a national opinion poll.

An additional 8% said the environment is in poor or very poor shape and won’t improve. — Woods Institute for the Environment at Stanford University / Associated Press
