Soil erosion is agriculture’s enemy: a major environmental threat to sustainability and productivity with knock-on effects on the climate crisis and food security.

This is particularly true for places with the highest risk of erosion, such as watersheds in Indonesia, India, the Philippines and more. In these areas, protecting against soil erosion through sustainable land management can solve a multitude of problems.
