Percentage of self-sufficiency for specific food groups*

From Stehl et al. Nature Food 2025 www.nature.com/articles/s43...

*National food availability from domestic production as proportion from recommended intake by the Livewell diet. 100% means that all recommendations of a food group are met.

That's super interesting, thank you for pointing it out! Indeed, such kind of consumption is generally not considered in national accounts based FAO data. However, compared to marked-sourced foods, picking or consumption from own production is extremely low and, thus, in most countries neglectable.

The research considered seven food groups that are part of the WWF's Livewell diet.

How many countries can feed their own population with a healthy and sustainable diet on their own? How many are vulnerable to breaks in supply - whether from war, natural disasters or trade problems?

Forschende haben untersucht, inwieweit 186 Länder ihre Bevölkerung allein durch die eigene Produktion versorgen können. Das Fazit: Internationaler Handel und Zusammenarbeit sind für eine gesunde und nachhaltige Ernährung unerlässlich.

Gap between national food production and food-based dietary guidance highlights lack of national self-sufficiency - Nature Food Recent global disruptions have revived the food self-sufficiency debate. This study analyses countries’ trade dependencies and the discrepancy between their domestic food production and guidelines for...

In our latest paper published in Nature Food, we study self-sufficiency patterns around the globe. We find that 1 in 7 countries is self-sufficient in 5 or more of the 7 food groups analyzed.
Huge thanks to my coauthors, Alexander Vonderschmidt, Sebastian Vollmer, Peter Alexander and Lindsay Jaacks.

654 Millionen Menschen leben in extremer #Armut. Aber wie viele weitere Menschen weltweit können sich keine angemessene Ernährung leisten?

Forschende unserer Uni betonen, dass die derzeitigen Armutsmetriken dies und die langfristigen gesundheitlichen Folgen übersehen:

654 million people live in extreme poverty. But how many more people worldwide cannot afford a basic nutritious diet?

Researchers highlight that current poverty metrics overlook this and the longterm health consequences: www.uni-goettingen.de/en/3240.html...

Current poverty measurement is designed around actual food consumption of the poorest. In our new paper in Food Policy, Lutz Depenbusch, Sebastian Vollmer, and I integrate least-cost healthy diets into poverty measurement. We present 3 approaches that vary in how non-food costs are considered.

New paper uses lowest-cost healthy diets in each country plus alternative definitions of other basic needs to measure the extent and depth of global poverty.

Chinese development finance and public opinion Foreign aid is often used as a tool by donors to shape public perceptions in developing countries. Yet there is little systematic evidence on whether and to what extent international development
