A group of British and American scientists have said that the world needs to prepare itself for global food shortages in the near future.
Speaking at an annual meeting of the American Association for the Advancement of Science (AAAS), the scientists unveiled disturbing new research that suggests future extreme events could affect the global food system so dramatically that it will result in ‘food shocks’ across the world.
Food shocks have the potential to wreak havoc on food markets, commodity exports, and families around the world.
Because distant regions are increasingly connected by global markets, the threat of extreme events occurring in different breadbaskets simultaneously is especially concerning. For example, what if severe drought in the US Midwest withers the soy and maize harvest at the same time that a record-breaking heat wave in Europe bakes the continent’s wheat crop?
In a report released last year, an independent expert taskforce from the UK and USA outlined key recommendations to safeguard against threats to food supplies.
At the AAAS meeting, researchers from the taskforce will discuss the impact of new research and outline the prognosis for 2016.
Kirsty Lewis, Applied Climate Science Team Leader at the UK’s Met Office, will:
- Discuss how our understanding of the geography of food production interacts with meteorology to compound the threats to food production in certain areas.
- Comment on the seasonal forecasts and discuss the relationship between the global food system and current El Nino-driven weather patterns.
Joshua Elliott, Computation Institute, University of Chicago, will present:
- Findings from ground breaking international projects to map the effects of climate change on crops around the world.
- Evidence for increasing risk to global agriculture from larger and more frequent extreme events as climate changes.
- New work on the risks posed by a 21st century Dustbowl-like drought to key commodity crops in the US Midwest and central plains.
Prof Tim Benton, Champion of the UK’s Global Food Security Programme – which coordinated the task force’s report will discuss the recommendations and the ways in which we can develop resilience against the increasing likelihood of food shocks.
Prof Tim Benton said, “The global interconnectedness that makes countries more resilient to local production shocks makes them more vulnerable to shocks in distant ‘breadbasket’ regions. Crop yields and climate data show us that the global food system is at increased risk as extreme weather events are as much as three times more likely to happen as a result of climate change by mid-century”.
