Improving the resilience and quality of rural road infrastructure
Through landslide management and optimisation of road reserve use
Abstract
Landslides are recurring natural phenomena that occur frequently in the Ugandan mountain areas of Rwenzori, Mufumbiro and Elgon. Maintaining the stability of the road reserve and its associated engineering assets is a priority for the Uganda National Road Authority, and this requires a focus not only on earthworks slopes but also the wider terrain in which the road is constructed. A web-based landslide data inventory has been set up within the Uganda National Road Authority to record landslide events and impacts and this will be combined with other GIS and remote sensing sources to develop a map of hazard-prone areas. The establishment of guidelines to maximise environmental and social benefits through optimum management of the road reserve, integrating engineering with community participation and agricultural extension would also be of benefit to future practice.
