What's New

Populations around the world continue to struggle with malnutrition – both undernourishment and overweight/obesity – and climate change may exacerbate the problem. In addition to reducing overall agricultural yields, higher temperatures and erratic precipitation could increase spoilage of nutritious and perishable foods like fruits and vegetables. Climate change could even make foods themselves less nutritious; increased CO2 levels can reduce the protein content of certain crops, such as soybeans and grains.

The prolonged heatwave of summer 2018 has devastated crops across Europe, leaving some countries facing their worst harvests since the end of World War II.

The hot temperatures and lack of rainfall, especially in central and Eastern Europe, has forced major exporting countries to import food for the first time in decades. Some countries are facing rising food prices as a result, while others, such as the UK, experience fruit and vegetable shortages in supermarkets.

As climate change continues to bring more frequent weather shocks, such as drought and flooding, and make rainfall patterns more erratic, smallholder farmers in developing regions like Africa south of the Sahara are often hardest hit. A new e-book from IRIN reports that mean temperatures in the region are expected to rise faster than the global average, leading to reduced agricultural yields and increased poverty and food insecurity.
