RESUMO:

This thesis addresses critical issues related to soil degradation, food security, and sustainable land management, focusing on Mali, a region particularly vulnerable to soil erosion. This phenomenon severely threatens agricultural productivity, food security, and environmental resilience. The research contributes directly to the United Nations’ 2030 Agenda for Sustainable Development Goals (SDGs), emphasizing SDG 2 (zero hunger), SDG 3 (good health and well-being), SDG 6 (clean water and sanitation), SDG 13 (climate action), SDG 15 (life on land), and SDG 17 (partnerships for the goals). The study employs advanced remote sensing technologies, including unmanned aerial vehicles (UAVs) and geospatial analyses, to develop innovative methods for monitoring and mitigating soil erosion. Using data from UAVs and the Revised Universal Soil Loss Equation (RUSLE), the thesis offers an improved model to evaluate erosion risk and pinpoint regions most vulnerable to deterioration. This model provides detailed insights to support the formulation of more precise and effective soil management strategies. Beyond technical analysis, the research adopts a multidisciplinary approach to investigate the broader implications of UAV technologies in rural communities. It examines ways to use these tools for environmental monitoring, promoting sustainable agricultural practices, improving water and sanitation systems, and enhancing community resilience. Through collaboration with local stakeholders, the study introduced sustainable land management practices and solutions tailored to the cultural and social needs of the local context. The findings underscore the transformative potential of remote sensing technologies in combating soil degradation, fostering ecosystem restoration, and mitigating the effects of climate change. In addition to proposing scalable and replicable solutions for other contexts, the thesis highlights the importance of integrating technological innovations with community-centered initiatives, significantly contributing to academic research and practical environmental management.
