Assessment Report: Integrating Climate Change Adaptation and Water Management in the Design and Construction of Roads

This report assesses the scope for making use of roads for building climate resilience and improved water management in Mozambique. With 30,121 kilometres of roads in Mozambique the more systematic integration of road maintenance/ improvement and water management presents an important opportunity to increase climate resilience.

Road Crossings for Water Harvesting in Dry Rivers: Non-Vented Drifts as Sand Dams

This Practical Note discusses the siting, the design and the construction of road crossings in dry
riverbeds to harvest and retain flood water. With extensive road construction programs ongoing in
most part of the world and 60% of new roads to be added from 2010 to 2025 globally, the
opportunities to combine road development with water management are substantial. Within this the
use of road drifts – in particular the use of nonvented drifts functioning as sand dams in semiarid
and arid areas – is an important and in most countries underutilized opportunity to harvest flood
water. Read the note here.

New video! The Promise of Roads for Polder Water Management and Flood Protection in Bangladesh

Bangladesh’s polder areas support the lives and livelihoods of more than 8 million people. The key issue within the polders is drainage, exacerbated over the years by the rise in level of coastal rivers due to siltation and sea-level rise due to climate change. Want to learn some of the solutions? Watch this video

Roads for Water: experiences from Malawi

New video from a field visit to a site in the Lilongwe district of Malawi, where road water diversion and harvesting structures have been created by a group of farmers. Thanks to the water harvesting, there is less soil erosion and gullies, as well as better crops and emergence of springs as a result of groundwater recharge. Watch the video here

New video: Floodways in floodplains: Preserving wetland functions’ and use

While preserving the functions of wetlands, floodways reduce the impacts of roads on floodplains allowing the water to pass trough the road in a controlled manner. By using this approach, damage produced by soil and water erosion to the road is also reduced with complementary measures such as rock cladding on the sides of the road and tree planting along the road.

Road-side borrow pits as ponds for off-season small-scale irrigation

This case study discusses the systematic conversion of borrow pits as rainwater harvesting ponds for off-season small-scale irrigation. The overall goal of this case study is to contribute to the replication and scaling up of borrow pits for off-season small-scale irrigation in arid and semi-arid areas. Read the study here
