If climate change is left unchecked, rising temperatures, extreme weather and land degradation could trigger a global food crisis, according to a new report released Thursday by a United Nations panel.examined how agriculture will be affected by global warming, as well as how food production and other changes in land use are expected to contribute to climate change in the future.
Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies in New York City and one of the coordinating lead authors of the IPCC report, said much of the world relies on trade to access food, which increases global vulnerability if food production is impacted across several regions at the same time.
Naylor’s research has also suggested that global warming could enable some weeds and pests to proliferate and could weaken certain crops’ ability to fight disease. Similar results have been found with other crops, Rosenzweig said, but much more research is needed to understand how climate change will affect the nutritional value of food.Yet, in addition to being impacted by climate change, agriculture and other land uses are responsible for about 13 percent of the world’s carbon dioxide emissions, according to the IPCC report.
