Climate Change Threatens Food Production
Sep 11, 2014

We’ve all heard about the dangers of climate change on world food security. But according to new research by 2050 our ability to produce food may be lowered by up to 10 per cent due to rising air pollution.

Human activities have increased the concentration of carbon dioxide in Earth’s atmosphere by over 30 per cent during the past 200 years and this figure is expected to double by the end of the century. The research found this change in air pollution inhibits the growth of field-grown wheat by 10 per cent. Air pollution will affect both urban and rural farming alike. Field-grown wheat is a staple crop for most developing countries, so if not addressed these findings show food security will suffer more than previously predicted. Adding to the crisis, worldwide food demand is set to rise by 50 per cent in 2050.

Climate change is already making people hungry. Rising temperatures and increasingly extreme and erratic weather patterns are making it harder to grow enough food to eat. Unfortunately, the situation is likely to get worse, placing an additional burden for our humanitarian work as drought and flooding become more frequent. Climate change threatens to put the fight to eradicate hunger back by decades.
