• •Climate change is increasing the frequency and intensity of heavy rainfall, a primary trigger for landslides.
• •Landslides are often underreported and lack the same level of mapping and insurance as other natural disasters.
• •Development on steep slopes, deforestation, and mismanagement of stormwater contribute to increased landslide risk.
• •The need for proactive measures, including improved mapping and public awareness, is crucial for mitigating the impact of landslides.

As climate change brings more extreme rainfall, the risk of landslides is increasing, particularly in mountainous regions. These events, often triggered by intense storms, are becoming more frequent and severe, leading to significant changes in landscapes and potential dangers to communities. The lack of comprehensive mapping and insurance for landslides poses challenges for risk assessment and mitigation. Increased development on slopes, combined with the effects of deforestation and changing weather patterns, further exacerbates the issue, making proactive measures and community awareness crucial for adapting to the changing environment.
