Facing a global crisis? We're at a critical juncture: millions are hungry, billions are grappling with weight issues, and our food systems are major contributors to environmental damage. But there's hope! A special issue of The Lancet Planetary Health, spearheaded by Cornell University experts, offers a roadmap for change.
This isn't just about tweaking our diets; it's about a complete overhaul of how we produce, distribute, and consume food. The issue, coordinated by Cornell's Food Systems and Global Change (FSGC) group, led by Professor Mario Herrero, dives deep into the complex challenges and potential solutions.
"This special issue is a significant contribution to the body of work on how to transform the food system for people and planet," Herrero emphasizes. It highlights the need for a multifaceted approach, balancing environmental protection, human health, and social justice.
The research builds upon the work of the EAT-Lancet Commission, a global team of experts. They realized there was so much more to say than could fit in their original report, prompting the creation of this special issue. Daniel Mason-D'Croz, a senior research associate, explains that our food systems are intricately linked to climate change, land use, and biodiversity loss.
"The food system is a bit like a water balloon: if you push down on one part of it, something else comes up," Mason-D'Croz explains. This means that solutions must be interconnected. We need to reduce emissions, use land and water more efficiently, ensure affordable access to healthy food, and provide fair wages to food producers.
But here's where it gets controversial... Shifting to healthier diets, as recommended by the EAT-Lancet Commission, could increase the consumption of fresh produce. However, because fresh produce spoils faster than processed foods, this could lead to more food waste. Marina Sundiang, a postdoctoral associate in FSGC, suggests that managing food loss and waste is essential to counteracting this. This includes strategies like consumers buying smaller amounts more frequently, communities increasing access to composting facilities, and governments investing in research to improve food storage and processing.
The special issue explores solutions for everyone: producers, consumers, and governments. For consumers, the key is adopting a healthy diet with moderate animal-sourced foods and plenty of fruits and vegetables. Producers should focus on increasing productivity and circularity (recycling nutrients). Governments must provide sustained support for scientific research and development to create new food varieties and management practices.
And this is the part most people miss... The research also highlights the need for collaboration. Matthew Gibson, a postdoctoral associate, hopes the special issue will spark new collaborations in food systems research and policy. He stresses the urgency of transforming systems at the necessary speed and scale.
The research was supported by the Cornell Atkinson Center for Sustainability, the Bill and Melinda Gates Foundation, and others. Key contributors came from institutions like Wageningen University, the Potsdam Institute for Climate Impact Research, and University College London.
