Erosion in areas susceptible to desertification in the semi-arid region: possibilities of analysis through geomorphological mapping based on very high-resolution images

In the Brazilian semi-arid region, erosion has already compromised the productive capacity of soils and generated serious socio-environmental phenomena in desertified areas. In this paper, we analyzed soil erosion in an experimental watershed with area of 2.92 km2, located in the Pernambuco State. F...

In this paper, we analyzed soil erosion in an experimental watershed with area of 2.92 km2, located in the Pernambuco State. From very high-resolution products derived from LiDAR sensors, UAV and field work, we produced the linear erosion map and the morphoconservation map.
