Short course road water harvesting Yemen

This short course was developed in Yemen on road water harvesting. Explaining what techniques can be of great use to facilitate beneficial water management.

In this short course training different methods of retaining and recharging water from roads, making use of on-going investment in roads development and rehabilitation to secure local water resources is explained deeply. It argues to take a multi-functional look at roads: whilst roads deliver transport and communication services, at the same time they can contribute to water security, flood control and erosion mitigation. In this way the high investment in road connectivity in Yemen can even render a much broader impact on livelihoods and economic development.

This short course training is initiated following extensive consultations with several water and agriculture sector organizations, and road authority in Yemen, as well as with international partners of WEC involved in the implementation of the Yemen Niche 027, Flood-Based Farming, Roads for Water and other projects.

Brochure: Road Development to Support Water Management and Flood Resilience

With 40,000 kilometres of embankment roads, polder roads and footpaths and a population of 30 Million in coastal polders of Bangladesh – roads provide a large opportunity to serve water management and flood resilience. “Roads to the Rescue” focuses on strengthening the practicality of using roads for water management within polders and making roads instruments for flood protection. Within the polders, rural transport structures such as roads, bridges, and culverts strongly influence water flow, distribution, and water levels. These structures can contribute to better management of flood inundation, can avoid flood drainage congestion, provide better embankments and provide flood and post flood shelters.

Comparative water quality analysis for road runoff water, case-study Kenya

A report that compares water quality parameters of water harvest from roads, rock catchment, river, borehole and a shallow well. It concludes that the water quality of road runoff is better off compared to other sources, only issues along road being exceeding values of high iron and turbidity. This can be prevented/treated with appropriate measures. Overall there is huge potential of road runoff also to be used for domestic use.

How to make roads work for resilience in Nepal?

Nepal is a challenging country for road design and construction: the low-lying plains that are prone to flooding and inundation, hilly areas with a lot of irrigation potential, and the mountains with very steep slopes.

We presented and discussed the challenges and opportunities at the Department of Roads. There is a lot of potential to turn roads into an asset for water management. The engineers indicated that the policy-aspect is very important, it needs to be included in decision-making.
