This manual, titled "Design and Implementation of Nature-Based Solutions in Rural Vietnam" aims to provide practical guidance for local authorities, practitioners, researchers, non-governmental organizations (NGOs), and community members engaged in climate adaptation, rural development, and ecosystem restoration. The objective is twofold: first, to offer step-by-step support for the design and execution of effective NbS in rural Vietnamese contexts; and second, to ensure these efforts are aligned with the internationally recognized IUCN Global Standard for Nature-based Solutions.
