Road construction often changes surface runoff patterns which, if unmanaged, can lead to water-related problems. The most common design approach in road development is to allow water to flow through hydraulic structures (roadside ditches, culverts, bridges) to ensure the safety of the structures. In many countries, water shortages are a common challenge. Research carried out in Ethiopia and other countries shows that water harvesting from roads has multiple benefits: it enhances soil moisture and groundwater recharge; it increases the availability of surface water for multiple uses; it reduces flooding and erosion at downstream areas; and it increases the resilience of local communities to droughts and rainfall variability. MetaMeta was given the assignment to assess and introduce the systematic use of roads for water management in Zambia. Read the full report Road Water Management for Climate Change”Zambia Report”
