Reforming the world’s food systems will be a key step in limiting global temperature rises, the UN has said, as it set out the first instalment of a roadmap for providing food and farming while staying within 1.5C.
Food production is highly vulnerable to the effects of the climate crisis, with research suggesting that as much as a third of global food could be at risk from global heating.
Agriculture and livestock farming are also major sources of greenhouse gas emissions, contributing roughly a 10th of global carbon output directly, and more than double that if the conversion of natural habitat to farming is included.
Until now, however, the UN has held back from setting out in detail how the world can both meet the nutritional needs of a growing population, which is forecast to reach 10 billion by 2050, and reduce global greenhouse gases to net zero by the same date. The latter is required to limit global temperature rises to 1.5C above pre-industrial levels.
The roadmap will be laid out over the next two to three years, starting with a document published at Cop28 in Dubai that contains 20 key targets to be met between 2025 and 2050, but little detail on how they can be met. Further detail on how the aspirations can be achieved will be set out in future instalments at the next two Cop summits.
The targets include: reducing methane emissions from livestock by 25% by 2030; ensuring all the world’s fisheries are sustainably managed by 2030; safe and affordable drinking water for all by 2030; halving food waste by 2030; eliminating the use of traditional biomass for cooking by 2030.
