There have been 180 landslides in Sri Lanka since 1945, says the National Building Research Organisation (NABRO), accroding to a Panos report. Indiscriminate tree-felling, poor drainage and unscientific construction have eroded the soil in areas like Nuwara Eliya, Kegalle and Kandy. With help from the United Nations Development Programme, NABRO is now mapping out areas prone to landslides and also devising an early warning system.
