Roads for Water and Resilience

Water is short in many places but roads are everywhere – and when it rains it is often along the roads that most water runs, as roads unknowingly either serve as a dike or a drain. By ‘harvesting’ the water with these roads, water shortage can be overcome and climate change addressed.

The potential to scale up the use of water with roads is enormous – especially with the on-going investment in road building globally – with every area having its own specific best solutions. At present, unfortunately the construction of roads often typically leads to local flooding, gully erosion, water logging, dust and sedimentation.  Yet this can be turned around and roads and water, rather than being enemies, can be friends.  Beyond the scope for harvesting water with roads, there is also another compelling argument: if done well, harvesting water with roads will reduce road damage and simply maintenance.

There is more – we believe that integrating road and water development where appropriate can also contribute to flood protection, sand harvesting, tree development, nature protection and sand dune control.  There are challenges in governance, social access and appropriate techniques, but all these challenges can be overcome.
