Food systems have enormous potential to support healthy diets and nutrition while also advancing livelihoods and prosperity and protecting the planet. Currently, however, food systems fail to deliver on this potential. Too often existing food systems are largely shaped by an array of piecemeal and even contradictory policies, resulting in widespread hunger, malnutrition, poverty, and environmental degradation. Because all the elements of the food systems interconnect, policies that influence one part of the food system have ripple effects across other parts, with implications beyond their immediate objectives. They thus bring both benefits and risks for different system objectives. Yet typically, these interconnections are not leveraged, with policies made in separate sectors siloed from each other. History shows that this approach is no longer adequate to tackle the huge global burden of multiple forms of malnutrition.
In 2021, the UN Food Systems Summit was called to address this missed opportunity. It sought to accelerate progress on the Sustainable Development Goals by leveraging the many connections between food systems and global challenges, such as hunger, climate change, poverty, and inequality. By taking a food systems approach to policymaking, the Summit suggested, governments could harness the power of food systems to benefit people and the planet. But what does it mean to take a food systems approach? How can interested policymakers adopt this approach and apply it to their contexts?
