Global food security at risk due to climate change

Staff writer |
Global warming and climate change will drive food prices to go up because of widespread hunger. According to Oxfam, the number of people possibly going hungry by 2050 due to climate change will rise to 20 percent of the overall population.

Oxfam noted that currently, farm yields are already affected by global warming. People already going hungry in the world's poorest nations will all the more get hungrier.

"The changing climate is already jeopardizing gains in the fight against hunger, and it looks set to worsen. A hot world is a hungry world. Extreme heat is also likely to reduce nutrients in crops, affect livestock growth and productivity and increase crop contamination by poisonous fungal mycotoxins, the report warned," Oxfam said. "A hot world is a hungry world."

Oxfam found that global yields of maize were 3.8 percent below over the past three decades, and wheat was 5.5 percent lower in the same period.

"These creeping, insidious changes in the seasons, such as longer, hotter dry periods, shorter growing periods and unpredictable rainfall patterns are bewildering farmers," Oxfam said.

United Kingdom wheat yields fell to their lowest levels in 20 years following the 2012 wettest year on record. The country was forced to import 2.5 million tonnes of wheat to sustain food supplies. In the U.S., global prices of maize shot up as much as 40 percent following the 2012 drought in the Midwest. Oxfam believed such scenario will become more frequent.
