The costs of climate change

A recent study by the International Food Policy Research Institute (IFPRI), titled ‘Climate change: Impact on agriculture and costs of adaptation’, highlighted some of the anticipated costs of climate change:

  • 25 million more children will be malnourished in 2050 due to climate change without serious mitigation efforts or adaptation expenditures
  • Irrigated wheat yields in 2050 will be reduced by around 30% and irrigated rice yields by 15% in developing countries
  • Climate change will increase prices in 2050 by 90% for wheat, 12% for rice and 35% for maize, on top of already higher prices.
  • At least US$7 billion a year are necessary to improve agricultural productivity to prevent adverse effects on children.
