"The past six years have been a success story in terms of global food security. Two hundred million fewer people are food insecure today than they were six years ago. The challenge we now face is whether we can maintain and even accelerate this progress despite the threats from climate change," said Agriculture Secretary Tom Vilsack.
"The report found that climate change is likely to cause disruptions in food production and a decrease in food safety, which in turn leads to local availability limitations and increases in food prices, with these risks greatest for the global poor and in tropical regions," said Dr. John Holdren, Assistant to the President or Science and Technology and Director of the White House Office of Science and Technology Policy. "Accurately identifying needs and vulnerabilities, and effectively targeting adaptive practices and technologies across the full scope of the food system, are central to improving global food security in a changing climate."
Major findings of the report are:
- Climate change is very likely to affect global, regional, and local food security by disrupting food availability, decreasing access to food, and making utilization more difficult.
- The potential of climate change to affect global food security is important for food producers and consumers in the United States.
- Climate change risks extend beyond agricultural production to other elements of global food systems that are critical for food security, including the processing, storage, transportation, and consumption of food.
- Climate risks to food security increase as the magnitude and rate of climate change increase. Higher emissions and concentrations of
greenhouse gases are much more likely to have damaging effects than lower emissions and concentrations. - Effective
adaptation can reduce food systemvulnerability to climate change and reduce detrimental climate change effects on food security, but socioeconomic conditions can impede the adoption of technically feasible adaptation options. - The complexity of the food system within the context of climate change allows for the identification of multiple food security intervention points, which are relevant to decision makers at every level.
- Accurately projecting climate change risks to food security requires consideration of other large-scale changes.
