Farmers are used to dealing with weather, but climate change is making it harder by altering temperature and rainfall patterns, as in this year’s unusually cool and wet spring in the central U.S. In a recently published study, I worked with other scientists to see whether climate change was measurably affecting crop productivity and global food security.

To analyze these questions, a team of researchers led by the University of Minnesota’s Institute on the Environment spent four years collecting information on crop productivity from around the world. We focused on the top 10 global crops that provide the bulk of consumable food calories: Maize (corn), rice, wheat, soybeans, oil palm, sugarcane, barley, rapeseed (canola), cassava and sorghum. Roughly 83 percent of consumable food calories come from just these 10 sources. Other than cassava and oil palm, all are important U.S. crops. Read the rest of this entry »

International food prices have increased steeply in the past six months, bringing the UN Food and Agriculture Organization (FAO) Food Price Index to its highest level since the high food price crisis in 2008 (only 16 points short from its peak in June 2008)

  • In many of the countries where WFP works, food prices remain above long-term averages, and higher than the period before the 2008 high food price crisis
  • WFP is monitoring the market situation carefully as price rises can hit the hungry poor hard and as more than half of WFP’s food is purchased with cash donations, higher prices can mean less food for the hungry
  • Climate change is expected to hit developing countries the hardest. Its effects— higher temperatures, changes in precipitation patterns, rising sea levels, and more frequent weather-related disasters—pose risks for agriculture, food, and water supplies
  • World population is projected to rise to 9.1 billion in 2050 from a current 6.7 billion, requiring a 70 percent increase in farm production

With the world facing the double dilemma of rapidly increasing demand for agricultural commodities and changing climates that affect our ability to produce food, it raises our awareness of the importance of linkages. Under its mandate, FAO has developed strong experience and expertise not only to fight poverty and hunger and to ensure environmental sustainability, but as this report shows, the output of the Organization links across the whole MDG universe.  Read the document>>>>
