Hazard Zoning and Land Classification

Environmental Conservation and Ecosystem- Based Solutions

Preserving and recuring natural vegetation - forests, graslands, wetlands - plays a cucial role in slope stabilization. Root systems bind soil, while plant canopie contract rainfall andd reduce erosion. Sustainable land use planning prioritizes the protection of green corridors, steep hillsides, and riparian zone s autural buffers.

Urban Density Control and Compact Development

Infrastructure Design for Slope Stability

Even in low- and moderate- risk areas, proper infrastructure design is essential. This includes includes diservered retaing walls, surface and subsurface drainage systems, slope diment using soil nails or anchored walls, and proper grading of construction sites.

Restoring i Maintenaing Natural Vegetation

Rapid urbanization often strips vegetation from hillsides. Reforestation and thee establiment of protected green belts on slopes can reduce landslide risk by 30- 50% according to some studies.
