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.
