In anthropized environments such as agricultural zones, soil degradation significantly impacts crop productivity, environmental and economic Sustainability. This degradation is often accelerated by man with inadequate management. The risks associated with soil degradation are particularly pronounced in tropical regions, where extremely weathered soils and rainfall dynamics exacerbate erosion. Soil loss due to erosion is a subject already known by the scientific community and producers with global estimates, but its characterization in the tropical environment is still a dimension that is poorly integrated on a local scale. In this context, this study aimed to validate the use of a simple RGB camera on a Unmanned Aerial Vehicle (UAV) to quantify small-scale erosion in Curral de Cima municipality, Paraíba, Brazil. To this end, a monitoring strategy with biweekly observations over a course of a year was implemented. The results indicate. In this context, and based on this validation, this work proposes to discuss the interest of PRAs in the integrated management of soil, water and economic resources in a tropical environment, demonstrating their interest in integrating the panel of precision agriculture tools by also supporting the “conservation” dimension,thus being able to value soil degradation remotely.
