World Wildlife Fund (WWF), in partnership with the US Agency for International Development Office of US Foreign Disaster Assistance (OFDA), developed the Natural & Nature-based Flood Management: A Green Guide (Flood Green Guide) to support using natural and nature-based methods for flood risk management. The Flood Green Guide is an open-source resource that is supported by training and a resource library. The Flood Green Guide Web Platform consists of flood news and information, chapter summaries of the Flood Green Guide, a Flood Green Guide forum, and flood management resources.
