The value of avoided losses

In recent weeks, Seychelles has experienced significant climatic events characterised by heavy rainfall, triggering landslides across the islands. During periods of intense and prolonged rainfall, soil saturation and pore-water pressure increase, contributing to slope instability. The islands' steep terrain – undoubtedly a defining feature of their natural beauty – combined with particular geological conditions, further heightens their vulnerability to landslides.

Seasonal north-westerly winds associated with the Indian monsoon can also contribute to slope instability. These weather conditions place considerable stress on vegetation, particularly trees with shallow or compromised root systems, potentially weakening the natural structures that help stabilise slopes.
