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.
Climate-Resilient Infrastructure for Urban Flood Risk Management in San Salvador de Jujuy, ArgentinaThis report showcases an economic assessment conducted by the Municipalidad de San Salvador de Jujuy, the Ministerio de Obras Públicas de Argentina, and the World Bank on different methods to restore the Alvarado Canal, including nature-based infrastructure.
Access to actionable information that outlines opportunities for nature-based solutions (NBS) investments at early stages of project design is essential for enabling the scale up of these solutions, which can effectively reduce climate risks, while bringing important socioeconomic benefits. This report summarizes how the Nature-Based Solutions Opportunity Scan (NBSOS) can support the World Bank, its clients, and development partners to identify NBS investment opportunities, understand the associated benefits, and integrate these interventions into projects.
This story highlights the Resilient Urban
Sierra Leone Project, which is supporting
the capital city of Freetown in
the restoration of its canopy
cover through community-based
reforestation.
This report relies on a combination of existing and pro¬totype InVEST models to map and model the value of services provided by the Haizhu National Wetland Park in Guangzhou (China). The report also demonstrates a globally generalizable approach to urban ecosystem service valuation.
