A new study from FAO (Food and Agriculture Organization of the United Nations) conclude that land degradation is an increasing problem in big parts of the world. The study has been ongoing for 20 years and show that more than 20 percent of all cultivated areas, 30 percent of forests and 10 percent of grasslands are undergoing degradation.
This is a big problem as 1.5 billion people depends on the land that is degrading and this can cause starvation for the people involved. This in turn can cause mass migration and destabilization.

Something that would help on land erosion is turning bigger parts of the agriculture industry to organic farming as this type of farming cares about erosion.
