Ecosystem-based Disaster Risk Reduction in Japan: A handbook for practitioners

Urban Farm DB summary

A practitioner handbook compiled by Japan's Ministry of the Environment on Eco-DRR (Ecosystem-based Disaster Risk Reduction). It systematizes the use of ecosystems and traditional land use—forests preventing soil erosion, coastal forests attenuating tsunamis, wetlands and paddy fields providing temporary flood storage—to achieve disaster risk reduction and biodiversity conservation simultaneously, providing a policy basis for treating urban and rural farmland and greenery as protective green infrastructure.

This handbook, published by Japan's Ministry of the Environment in 2016, provides practical guidance on Ecosystem-based Disaster Risk Reduction (Eco-DRR). It systematically outlines how traditional land use and natural ecosystems can be leveraged for disaster prevention and mitigation. Examples include forests for soil erosion control, coastal forests for tsunami attenuation, and wetlands and paddy fields for temporary flood storage. The document emphasizes achieving both disaster risk reduction and biodiversity conservation concurrently. Ultimately, it establishes a policy framework for recognizing urban and rural farmlands and green spaces as vital green infrastructure for disaster resilience.
