Move to sustainable food systems could bring $10tn benefits a year, study finds
A shift towards a more sustainable global food system could create up to $10tn (£7.9tn) of benefits a year, improve human health and ease the climate crisis, according to the most comprehensive economic study of its type.
It found that existing food systems destroyed more value than they created due to hidden environmental and medical costs, in effect, borrowing from the future to take profits today.
Food systems drive a third of global greenhouse gas emissions, putting the world on course for 2.7C of warming by the end of the century. This creates a vicious cycle, as higher temperatures bring more extreme weather and greater damage to harvests.
Food insecurity also puts a burden on medical systems. The study predicted a business-as-usual approach would leave 640 million people underweight by 2050, while obesity would increase by 70%.
The study proposes a shift of subsidies and tax incentives away from destructive large-scale monocultures that rely on fertilisers, pesticides and forest clearance. Instead, financial incentives should be directed towards smallholders who could turn farms into carbon sinks with more space for wildlife.
A change of diet is another key element
Overall, they estimate the costs of the transformation at between 0.2% and 0.4% of global GDP per year.
As well at the climate impact, it is a major driver of land-use change and biodiversity decline, and is responsible for 70% of freshwater drawdown.
Numerous other studies have demonstrated the health and climate benefits of a shift towards a plant-based diet.
A report last year by the Climate Observatory notes that Brazil’s beef industry – and its related deforestation – now has a bigger carbon footprint than all the cars, factories, air conditioners, electric gadgets and other sources of emissions in Japan.
Changing the ways we produce and consume food will be critical to tackling climate change, protecting biodiversity, and building a better future. It is time for radical change.”
The new study is not prescriptive about vegetarianism, but Rockström said demand for beef and most other meat would fall if hidden health and environmental costs were included in the price.
The main challenge of the proposed food transition is that costs of food would rise. Rockström said this would have to be handled with political dexterity and support for poor sections of society otherwise the result could be protests, such as the gilets jaunes (yellow vests) demonstrations held in France over petrol price hikes.
This opportunity should capture the attention of any policymaker who wants to secure a healthier future for the planet and for people.”
