Transforming food systems could create multi-trillion dollars of economic benefits
A new global policy report produced by leading economists and scientists of the Food System Economics Commission (FSEC) reveals that food systems are destroying more value than they produce and that an overhaul of food system policies is urgently needed. The costs of inaction to transform the broken food system will probably exceed the estimates in this assessment, given that the world continues to rapidly move along an extremely dangerous path.
“It is likely that we will not only breach the 1.5°C limit, but also face decades of overshoot,” states Johan Rockström, Director of the German Potsdam Institute for Climate Impact Research (PIK) and FSEC Principal. “The only way to return to 1.5°C is to phase out fossil-fuels, keep nature intact and transform food systems from source to sink of greenhouse gases. The global food system thereby holds the future of humanity on Earth in its hand,” he adds.
Making food systems powerful means to potentially save 174 million lives from premature death
In the report, which was launched on the 29th of January, the scientists provide the most comprehensive modelling of the impacts of two possible futures for the global food system to date: the “Current Trends” pathway and the “Food System Transformation” pathway. In its “Current Trends” pathway, the report outlines what will happen by 2050 even if policy-makers make good on all current commitments. Food insecurity will still leave 640 million people (including 121 million children) underweight in some parts of the world, while obesity will increase by 70 per cent globally.
Food systems will continue to drive a third of global greenhouse gas emissions, which will contribute to 2.7 degrees of warming by the end of the century compared to pre-industrial periods. Food production will become increasingly vulnerable to climate change, with the likelihood of extreme events dramatically increasing.
The Commission also finds that the food system can instead be a significant contributor to economies, and drive solutions to health and climate challenges. In the “Food System Transformation” pathway, economists show that, by 2050, better policies and practices could lead to undernutrition being eradicated, and, cumulatively, 174 million lives being saved from premature death due to diet-related chronic disease.
Food systems could become net carbon sinks by 2040, helping to limit global warming to below 1.5 degrees by the end of the century, protecting an additional 1.4 billion hectares of land, almost halving nitrogen surplus from agriculture and reversing biodiversity loss.
Furthermore, 400 million farm workers across the globe could enjoy a sufficient income. “The cost of achieving this transformation – estimated at the equivalent of 0.2-0.4 per cent of global GDP per year – is small relative to the multi-trillion dollar benefits it could bring. Food systems are a uniquely powerful means of addressing global climate, nature and health emergencies at the same time – while offering a better life to hundreds of millions of people,” says Hermann Lotze-Campen, FSEC Commissioner and Head of Research Department "Climate Resilience" at PIK.
“Rather than mortgaging our future and building up mounting costs leading to high hidden health and environmental costs that we will have to pay down the line, policy-makers need to face the food system challenge head-on and make the changes which will reap huge short- and long-term benefits globally,” maintains Ottmar Edenhofer, PIK Director and FSEC Co-Chair. “This report should open up a much-needed conversation among key stakeholders about how we can access those benefits whilst leaving no one behind,” Edenhofer concludes.
The FSEC is an independent academic commission set up to equip political and economic decision-makers with tools and evidence to shift food and land-use systems. It brings together leading experts across the economics of climate change, health, nutrition, agriculture and natural resources, representing organisations including the Potsdam Institute for Climate Impact Research, the World Health Organization, the World Bank, the London School of Economics, the World Resources Institute Africa and many more.
