Researchers are discovering the benefits of combining forestry and agricultural activities.
‘Items in this section have limited availability due to supplier production issues,’ ‘Sorry, temporarily out of stock’ and ‘Sold out’ are all signs that became familiar as recent global upheavals exposed how precarious our food supply is.
The COVID-19 pandemic led to bare shelves in supermarkets as shipping routes were cut off. The war in Ukraine has affected the supply of essential grains.
But increased climate change stands to cause even greater disruption. Researchers say part of the solution to mitigating that risk is for farms to become more mixed through some combination of crop cultivation, livestock production and forestry, a move that would also make agriculture more sustainable.
For Dr Sara Burbi, assistant professor at Coventry University in the UK until December 2022 and now an independent researcher, COVID-19 was a wake-up call.
‘Suddenly, we experienced first-hand what happens when value chains are not resilient to shocks and what happens when globalisation, with all its intricacies, does not work anymore,’ she said. ‘We saw highly specialised farming systems fail when they over-relied on external inputs that they had no access to.’
Climate change, according to Burbi, could provide even bigger global shocks ranging from widespread crop failures to lower yields or damage from flooding. More sustainable agriculture is essential to ensure food supplies can withstand the impact of climate change and unexpected local, national and even global crises.
