According to the National Centre for Coastal Research, Chennai, almost one-third of India’s 7,517 km long coastline was lost to soil erosion between 1990-2016.

Abstract: Soil erosion is the removal of the top layer by natural agents. However, deforestation, overgrazing and infrastructural development accelerate soil erosion. As soil is a critical natural resource, the risk of its erosion must be addressed urgently. Use of modern technologies like remote sensing and GIS can help build an understanding towards risk mitigation.
