Dietary changes will help more sustainable agriculture meet increased global food demand

By Robert Lyons on 5th December 2016

Researchers have assessed how changes in production efficiency and dietary patterns can combine to ensure food supply whilst minimising the global environmental impact of food production. The gain in the production efficiency of agriculture was found to be insufficient to meet future food demand whilst preventing additional environmental burdens, if dietary trends continue to grow based on GDP. Changing consumption patterns, including switching to less resource-demanding diets, would contribute towards ensuring future food security whilst preventing further increases in agriculture’s environmental burden. Reducing terrestrial animal production offers significant advantages, but alternative diets can also present environmental and production trade-offs.
