Recent events such as the Covid-19 pandemic, locust infestations, drought and labour shortages have disrupted food supply chains, endangering food security in the process. A recent study published in Nature Food shows that trade restrictions and stockpiling of supplies by a few key countries could create global food price spikes and severe local food shortages during times of threat.
‘We quantified the potential effects of these co-occurring global and local shocks globally with their impacts on food security,’ explains Aalto University Associate Professor Matti Kummu. The results of this research have critical implications on how we should prepare for future events like Covid-19, he says.
The researchers modelled future scenarios to investigate the impact of export restrictions and local production shocks of rice, wheat, and maize would have on their supply and price. These three crops form the backbone of global trade in staple crops and are essential for food security across the globe.
