Green Roads for Water

Published on Jun 21, 2021

"Roads and water are generally seen as enemies, with water responsible for most of the damage to roads, and roads being a major cause of problems such as erosion, waterlogging, flooding, and dust storms. This tension, however, can be reversed. The concept of Green Roads for Water (also known as “Green Roads†? or “roads for water†?) places roads in the service of water and landscape management and climate resilience without sacrificing or diminishing their transport functions. With global investment in roads of US$1†“US$2 trillion per year, plus maintenance costs, the widespread adoption of Green Roads approaches can leverage investment at a transformative scale, making road development and maintenance a vital tool for achieving climate resilience, water security, and productive use of natural resources. Green Roads for Water: Guidelines for Road Infrastructure in Support of Water Management and Climate Resilience provides strategies to use roads for beneficial water management tailored to diverse
