>Food self-sufficiency (FSS) and healthy diets are high on policy agendas to ensure food security under increasing global pressures. A global shift towards self-sufficient production of healthy diets would represent a radical departure from today's globalised food system. Representing such scenarios in a biophysically consistent way requires accounting for multiple resource constraints and feedback loops—including feed, fertiliser, and trade flows—while allowing flexible reallocation of crop areas, livestock numbers, and biomass streams. We use the global biophysical optimisation model CiFoS (Circular Food Systems) to evaluate the potential for self-sufficient production of multiple food groups and nutrients in 70 regions by 2050 under a business-as-usual diet (BAU-MinTrade) and a Planetary Health Diet (PHD-MinTrade). FSS is assessed by minimising biomass and nutrient trade while fulfilling dietary requirements, with trade only balancing shortages. Results show that total trade could fall by 62% to 618 million tonnes in BAU-MinTrade and by 79% to 343 million tonnes in PHD-MinTrade. Many regions—including Europe, the Americas, Oceania, and China—could be almost self-sufficient under both scenarios. Several African regions, India, and parts of Asia would still rely on imports, especially under BAU-MinTrade. Most food groups and nutrients show potential for increased FSS, though trade in some animal-source products and nutrients may rise. Self-sufficient systems can keep land use and GHG emissions within planetary boundaries, but nitrogen and phosphorus inputs remain high. PHD self-sufficiency is consistently more sustainable than BAU. Aligning production with dietary shifts towards a PHD supports self-sufficiency while reducing environmental trade-offs.
Report intro:
The climate emergency is escalating, with increasingly alarming impacts on the food system. Animal agriculture is both highly dependent on a stable climate system and one of the biggest contributors to climate change, primarily through methane and nitrous oxide pollution and indirectly as a major driver of deforestation and land-use change.
Transformative changes are needed and shifting diets in many areas where meat and dairy are overconsumed is essential to bring down emissions and improve health. The 2025 EAT-Lancet report provides further evidence for how healthy and sustainable diets on a planet of 10 billion people are feasible, and how shifting to such diets would cut emissions from the food system in half and prevent 15 million premature deaths per year.
The last UN climate conference, COP30, took place in November 2025 in Belém in the Brazilian Amazon, and hopes were high that transforming agriculture and food systems would finally make it into an official conference text. However, this did not happen. Instead, agribusiness voices focused on efficiency and concerns around food security featured prominently across the conference, standing in the way of real change. While climate change is a real threat to food security, this narrative is reframed and exploited by meat and dairy industry actors to justify continued growth of animal agriculture.
Additionally, despite the scientific consensus that dietary shift and agricultural methane reductions are crucial to stay on a 1.5°C or even a 2°C-degree trajectory, just 4% of national climate plans (nationally determined contributions, or NDCs) include quantified, time-bound agricultural methane reduction targets, and fewer still include sustainable diets.
This briefing will unpick some of the key industry narratives that are being used to prevent the inclusion of food systems on the climate agenda. It highlights arguments and key messages pushed by meat and dairy industry representatives and allies at both the World Meat Congress, a biennial industry event which last year was held in Brazil just before COP30, and at COP30 itself.

>In 1930s Germany, Adolf Hitler promised national renewal through grand motorways and affordable cars for ordinary families. But behind the spectacle of the Autobahn lay a far darker reality. This documentary reveals how the Nazis turned road building into one of their most powerful propaganda tools, while failing to deliver most of what they promised. The so-called “People’s Car” scheme took workers’ money but never gave them the cars they paid for, as the factory was diverted to military production. Meanwhile, millions of forced laborers and prisoners were exploited under brutal conditions to support infrastructure designed less for prosperity than for war. Project Nazi: Hitler’s Highways exposes the gap between Nazi myth and reality - and how mobility became another instrument of dictatorship, deception, and destruction.
The documentary reveals lesser known aspects of the relationship between fascism, productivism, pro-growth, pronatalism, and racial supremacism.
>On today's episode, Katy, Cody, and Jonathan talk with Ed Zitron about Allbirds, Anthropic's Mythos, and other A.I. stories. After that they dig into JD Vance's fight with the Pope and Pete Hegseth sharing his favorite film quotes.

>Are Small Modular Nuclear Reactors (SMRs) really moving toward large-scale deployment or are the economic challenges highlighted by critics still unresolved? Can factory-built modular reactors reduce construction risk, shorten build times and lower costs through mass production? Or will shrinking reactors actually make them more expensive? The sceptics are quite certain of the answer but politicians keep barrelling ahead. So, will we ever really see an SMRs on the outskirts of major towns and cities around the world?
Learn how fossil hydrocarbons are involved in food. You'll understand which foods will get more expensive due to an oil and gas crisis.
>Whether it is crude oil, natural gas, or coal, these are unnervingly the base of much of our food supply!
