Is grazing cattle on land unfit for crops the best use of it?
Besvaret 1. november 2026
Partly. Livestock can turn grass and leftovers that people cannot eat into food. A systematic review of eight studies from Wageningen University found that animals fed only on grass and leftovers could supply 9 to 23 grams of protein per person a day, and that this frees up about a quarter of the world's cropland compared with a diet with no animal foods. But grassland is not idle: it could also be used for nature, forests or bioenergy. A global modelling study found that pastures on land where forest would grow naturally could hold on average more than 7 times as much carbon per hectare as pastures on natural grassland if nature were allowed back. In Denmark, grazing plays a small part: only about 220,000 hectares are permanent grassland, and Danish dairy farming makes little use of grazing apart from organic farms. That figure comes from the World Resources Institute, an environmental organisation.
