Implementing nature-based flood protection: Principles and implementation guidance

The objective of this document is to present five principles and implementation guidance for planning, such as evaluation, design, and implementation of nature-based solutions for flood risk management as an alternative to or complementary to conventional engineering measures. The potential users of these principles and implementation steps are professionals in risk management and climate adaptation, NGOs, donors, and international organizations. This guidance was developed in cooperation with a large and diverse group of international funding agencies, research institutes, NGOs, governmental organizations, and engineering firms. This document has two parts: 1. Principles, describing key considerations to consider when planning nature-based solutions 2. Implementation guidance, describing the timeline and activities needed to implement nature-based solutions
