THE ROLE OF GIS AND RS LAND SLIDE MANAGEMENT FOR ENVIRONMENT CASE STUDY: NYUNDO SECTOR (2014-2023)

Abstract

This study explores the critical role of Geographic Information Systems (GIS) and Remote Sensing (RS) in managing landslide disasters and protecting the environment, with a focused case study on Rubavu, Nyundo Sector in Rwanda. Landslides pose significant threats to both human life and infrastructure, particularly in regions characterized by steep terrain and heavy rainfall. Effective disaster management strategies are essential to mitigate these risks, and the integration of advanced technologies like GIS and RS offers promising solutions. On May 3, 2023, over 6,000 homes were wrecked by disasters in the Nyundo Sector, Rubavu District. This incident underscored the urgent need for robust disaster management systems. The government has identified various „disaster hotspots‟ across the nation prone to floods and landslides, emphasizing the critical need for advanced monitoring and prediction tools. The study aims to assess the effectiveness of GIS and RS in identifying and managing landslide-prone areas, evaluating their contribution to environmental protection, and providing actionable insights for local authorities and policymakers. By leveraging satellite imagery and spatial data. the study identifies high-risk zones, monitors environmental changes, and develops predictive models for landslide susceptibility. The methodology involves the collection and analysis of geospatial data, field surveys, and the application of risk assessment models to evaluate the landslide susceptibility of Nyundo Sector. This research contributes to the broader field of disaster management by demonstrating the practical applications of GIS and RS in a real-world context. The case study of Rubavu, Nyundo Sector serves as a model for similar regions facing the dual challenges of natural disasters and environmental degradation. The recommendations provided offer a pathway for integrating advanced geospatial technologies into comprehensive disaster management and environmental protection strategies, ensuring a safer and more sustainable future for vulnerable communities.
