Grist: This isnt just about plants and animals. Its about people, its about societies, says Gene Takle, a convening lead author of the National Climate Assessments Agriculture chapter. Climate disruptions to our food system have already increased in the last 50 years, and will continue to do so. Many regions will experience declines in crop and livestock production from increased stress due to weeds, diseases, insect pests, and other climate change-induced problems.

Rising CO2 levels to cut key nutrients in global crops
2014-05-16 01:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Boulder Weekly: New research studying 41 strains of six different crops on three continents that was published May 7 in the scientific journal, Nature, shows that as concentrations of atmospheric carbon dioxide increase, the nutritional content of key food crops will drop, exacerbating hunger woes for millions of people worldwide. In some crops, concentrations of nutrients could drop by as much as 10 percent when CO2 levels rise to 500 parts per million by mid-century. Harvard University public health researcher...
Corn crops increasingly vulnerable to dry spells

Agence France-Presse: U.S. farmers can grow more corn than ever before thanks to genetic modifications and improved planting techniques, but the crops are also increasingly vulnerable to drought, researchers recently said. The study in the journal Science found that "densely planted corn appears to be unexpectedly more sensitive to water scarcity," raising concerns about future food supply as the planet warms. The United States is the largest exporter of corn in the world, shipping about 40 percent of the world`s...

GMO crops benefit environment, farmers, developing countries
2014-05-09 19:17:00| Corn & Soybean Digest
Source: PG Economics Limited A recent review of biotech, or GM (GMO), crops shows that they offer major environmental benefits and allow farmers to grow more acres with fewer resources. In the 17 years of adoption, genetically modified crops delivered more environmentally friendly farming practices while providing clear improvements to farmer productivity, says Graham Brookes, co-author of the PG Economics report. read more
