Agri-environmental policies improve cropland around the world

Erosion, salinization and shrinking numbers of organisms such as worms and beneficial fungi can have a devastating effect on soil fertility, and so many parts of the world have passed laws to curb these processes. A study by the University of Bonn has now shown that these measures have improved soil quality in many countries. Their impact, however, is heavily dependent on the political and institutional environment in which they are implemented. The researchers’ findings have been published in the journal “Nature Food.”
