Armed conflict disrupts millions of lives and damages essential services, such as water, sanitation, and power. As part of its response, the ICRC restores these services and renovates public infrastructure through a public health engineering approach that manages various environmental factors impacting public health. These efforts also involve promoting the use of sustainable and innovative technologies to strengthen operational resilience. An example is a solar pumping water system in Dhahyan town, Yemen that reduces fuel consumption, serving the host community as well as the displaced population affected by the conflict.
