Green Roads for Water : Guidelines for Road Infrastructure in Support of Water Management and Climate Resilience

| Summary: | 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 landscapes and
climates, including watershed areas, semiarid climates, coastal lowlands,
mountainous areas, and floodplains. The underlying premise of Green
Roads is therefore quite simple: designing roads to fit their natural
and anthropomorphic contexts; minimize externalities; and balance
preservation of the road, water resources, landscape, and soil resources will
usually cost less than traditional protective resilience approaches and will
produce more sustainable overall outcomes. |
