Sri Lanka, Oct. 23 -- The National Building Research Organisation (NBRO) has now implemented a programme to stabilise landslide slopes to minimise the risk of landslides in identified areas.

Accordingly, approximately 250 stabilisation projects have been implemented in landslide-prone areas during the last 10 years. Approximately Rs. 10 billion was incurred for that purpose. The long-term stability of a stabilised landslide area depends on the measures taken to manage groundwater and surface water drainage patterns.

There is a risk of these stabilised areas turning back into non-stabilised areas without the management and maintenance of groundwater and surface water drainage patterns. Therefore, proper maintenance of these stabilised ar...
