Coastal zones are increasingly at risk from the combined effects of climate change, sea-level rise, intensifying storms, ecosystem degradation, and rapid coastal development. While traditional gray infrastructure has long been used for coastal protection, it is often costly, environmentally damaging, and increasingly insufficient under growing hazard conditions. Nature-based solutions (NBS) such as mangroves, dunes, reefs, and marshes offer a complementary and cost-effective approach to coastal resilience, reducing risks while benefitting biodiversity, livelihoods, and carbon storage.Published

Focused on nature-based solutions (NBS) for climate resilience and disaster risk reduction, this guide provides countries with approaches to address complex climate-related challenges while generating important socioeconomic benefits. Traditional conservation and restoration practices are also considered NBS when they aim for resilience or disaster risk reduction alongside human well-being. This guide focuses on NBS for climate resilience and disaster risk reduction (DRR).Published

This report provides an overview of the potential role that nature-based solutions (NBS) can play in ports. It aims to illustrate how NBS can be effectively integrated into port planning, design, and operations to address various port challenges, while offering opportunities to leverage climate resilience benefits and other cobenefits.Published

This report explores nature-based solutions (NBS) for beach stabilization within the Blue Economy framework, emphasizing sustainable ocean resource use for economic growth and ecosystem health. Coastal tourism, vital to developing regions and SIDS, benefits from these strategies. Targeting governments and tourism stakeholders, the report offers practical approaches to combat beach erosion, stressing that direct interventions should follow evaluation of non-intervention options.Published

This Sustainable Asset Valuation (SAVi) assessment examines the long-term economic, environmental, and social implications of the Bogotá River Environmental Recuperation and Flood Control Project, implemented with a loan from the World Bank. Carried out by the International Institute for Sustainable Development in collaboration with the World Bank, the assessment evaluates the performance of the interventions implemented in the middle basin. It also explores how hybrid infrastructure combining conventional grey works and naturebased infrastructure (NBI) adds value to the project. Beyond assessing the project impacts, the analysis seeks to inform future planning and emphasize the importance of basin-wide perspectives for effective river restoration.
Bangladesh is highly vulnerable to extreme weather events due to its frequent exposure to floods and extensive low-lying areas. Coastal flood risks are expected to increase due climate change. Therefore, Bangladesh has been upgrading its coastal embankment system to enhance flood safety. This initiative includes not only hard flood defense infrastructure, but also nature-based solutions through planting mangroves on the seaside of embankments. Mangroves, serving as natural flood barriers, have been utilized in Bangladesh for coastal protection since the 1960s. However, their integration with embankment designs and their benefits in carbon sequestration remain underexplored. This paper consolidates current knowledge on the role of mangroves in coastal resilience in Bangladesh, incorporating recent studies and new analyses on their benefits on (i) flood risk reduction, (ii) livelihood enhancement, and (iii) carbon sequestration.
This report provides a cost-benefit analysis of a Government of Indonesia plan to use nature based solutions to restore or enhance the protection of 600,000 ha of mangroves by 2025.
This CCDR highlights how climate action offers an opportunity to safeguard development gains and accompany the ambitious transformation Senegal is embarking on to achieve its objective of reaching middle income status in the next decade. It notes NBS opportunities in Greater Dakar, which were identified through GPNBS' NBS Opportunity Scan.
This regional Country Climate and Development Report (CCDR) focuses on four countries of the 11‑member Organization of Eastern Caribbean States (OECS) and identifies opportunities for these countries to increase cliamte resilience, including through the application of NBS.
