When vocational training applicants fare better in business training programmes
Reassigning young women in Liberia from oversubscribed job-skills training into business-skills training substantially improved their employment and earnings, though the gains were concentrated among those with higher education and prior entrepreneurial experience, who had themselves underestimated their fit for business.

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.

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? Find out more: www.uni-goettingen.de/en/3240.html..., #NatureFood: www.nature.com/articles/s43...

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 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... #FoodPolicy: doi.org/10.1016/j.fo...

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. Great work from @jonasstl.bsky.social & coauthors @unigoettingen.bsky.social, much needed for #TeachEcon #EconSky & #FoodSky
