Landslip and stream bank stabilisation

Integration of vegetative and structural measures for landslip, stream bank and gully stabilisation on hillsides

A combination of measures were implemented by a group of neighbouring families in the middle hills of Nepal to mitigate the problems caused by landslips, gully formation, and stream bank erosion problems in a local area. These processes were affecting the stability of adjacent agricultural land and causing problems downstream. Small-scale farming is dominant in the area surrounding the treated land – which belongs to the government but is used by these families.

This pilot technological package is proving suitable in Nepal for steep/very steep slopes under humid subtropical climates within the altitudinal range of 1,000–1,500m. This type of intervention, combined with the active involvement of stakeholders (who contributed three-quarters of the costs), was introduced to Nepal under a watershed management programme co-funded by the European Commission (see ‘Integrated watershed management QA NEP11’).
