A new study on climate change patterns indicates that climate change could reduce total crop production 23 percent by 2050, the same year in which human population is expected to increase past nine billion people.

Globally, one in nine people were unable to meet their dietary energy requirements in 2015 and that number is expected to increase. Food insecurity is exacerbated by unstable global food prices, which are a reflection of unpredictable crop production seasons due to extreme weather patterns like temperature shocks, drought and flooding.

Climate-resilient agriculture has been touted as essential to achieving food security in the future. The study shows that improvements in technology and agronomic practices have the capacity to increase global food production to adequate levels, even in extreme conditions.

The authors say that beginning to implement mitigation and adaptation technologies now is crucial to check climate change’s adverse impact on global crop production and food security.
