Geospatial Applications in Modeling Climate Change Impact on Soil Erosion

Soil erosion by water is one of the major threats to the society and the economy in different parts of the world affecting agriculture. It is major land degradation process occurring throughout the world that adversely affects ecosystem services, crop production, and water quality and carbon emission to the atmosphere. The hydrological processes associated with soil erosion influence soil nutrients and are intricately associated with crop productivity. Therefore, climate change may have a serious threat in terms of soil productivity due to the loss of significant amount of soil carbon from the agriculture soils. IPCC predicted intense rainfall events resulting erosive rainfall in upcoming decades that will be influencing the severity and extent of soil erosion in future. Climate change study deals with the long-term impact of air temperature and precipitation that may affect vegetation growth and soil hydrological parameters influencing soil erosion processes. Changes in precipitation amount and patterns will influence the soil erosion process by affecting runoff generation and rainfall erosivity in future.
