Software for Soil: Computer Assisted Design can Check Erosion
The soil is in trouble. About one-third of the world’s land is moderately to highly degraded, suffering from erosion, salinization, acidification or chemical pollution or some combination of those (FAO, 2015). Erosion in particular poses a major threat to global food security. Runoff carries away 25-40 billion tons of topsoil every year, reducing crop yields and impairing the soil’s ability to store and cycle carbon, nutrients, and water. This degradation of soil quality is a considerable setback to achieving the UN’s Sustainable Development Goal 2 in the 2030 agenda: Zero Hunger.
