The Flood Green Guide, published by WWF International, advocates for an Integrated Flood Management (IFM) approach that prioritizes non-structural methods and combines 'soft' (nature-based) and 'hard' (engineered) structural interventions. It provides a five-stage project cycle—preliminary analysis, method identification, selection and design, operation and monitoring, and project evaluation—to help local managers reduce flood risk. The guide details various techniques, from upper watershed restoration and constructed wetlands to engineered drainage and land-use zoning, while emphasizing the importance of gender analysis, community engagement, and the specific challenges of urban flooding, such as the urban heat island effect and land subsidence.
