Researchers at ETH Zurich and the Carnegie Institution for Science have shown how nitrogen fertilizer could be produced more sustainably. This is necessary not only to protect the climate, but also to reduce dependence on imported natural gas and to increase food security.

The potato is known to be a good source of energy, potassium, and vitamins C and B6, but according to research recently published in the Journal of Nutrition, its tubers can also be an excellent source of iron.

Researchers from Australia, Germany, Switzerland and the US have quantified the effect of climate extremes, such as droughts or heatwaves, on the yield variability of staple crops around the world.

Worldwide about a third of all food gets lost before it reaches our stomachs. For Swiss potatoes this is even more – half of the total harvest. Which measures can reduce the loss, and what effect do they have?
