CDS was appointed by Mott Macdonald of UK in 2015/16 to provide specialised rural roads engineering inputs to a study of Climate Resilience of the Road Network in the Lower Limpopo Valley in Mozambique. The assignment included an assessment of vulnerability of road infrastructure to extreme weather variability, in particular flooding during periodic cyclonic events, and identification of options for building resilience to climate change. CDS developed design schemes for modifying existing embankments across water courses to make them less prone to major damage following inundation during floods. This included reshaping the embankments with a horizontal road surface and flatter side slopes protected against erosion with deep rooted local grass varieties.  The roads in the project area carry very little traffic so cost effective and affordable designs were required.
