This Sustainable Asset Valuation (SAVi) report assesses the economic and environmental impact of nature-based infrastructure (NBI) and hybrid infrastructure interventions in the Bogotá River basin, concluding that these investments provided significant net benefits in flood protection and water quality.

This Sustainable Asset Valuation (SAVi) assessment evaluates the economic, social, and environmental performance of nature-based solutions (NbS) implemented under the SUNCASA project in Kigali, focusing on cost-benefit analysis and climate resilience.

This report presents a Sustainable Asset Valuation (SAVi) assessment of Nature-based Solutions (NbS) implemented in Kigali, Rwanda, as part of the SUNCASA project. Using an integrated cost-benefit analysis (CBA) for the period 2025–2050, the study quantifies the economic, social, and environmental impacts of interventions such as afforestation, reforestation, agroforestry, and urban tree planting. The assessment finds that these NbS interventions are economically viable, providing significant avoided costs related to flood damage and health, alongside added value from carbon sequestration and employment.

This report presents a Sustainable Asset Valuation (SAVi) assessment of nature-based solutions (NbS) implemented by the SUNCASA initiative in the Dechatu River catchment in Dire Dawa, Ethiopia. The assessment evaluates the economic, environmental, and social performance of interventions such as afforestation, agroforestry, and urban tree planting, finding that these measures provide significant returns in flood risk reduction, carbon sequestration, and job creation.

The Nature-Based Infrastructure Global Resource Centre conducted a cost-benefit analysis of nature-based infrastructure (NBI) for waterway rehabilitation in Cape Town, South Africa, specifically within the Diep/Sand River and Zeekoe catchments. The analysis demonstrates that NBI interventions—such as creating retention ponds, extending wetlands, and removing invasive species—provide significant economic returns, reduce long-term maintenance costs compared to grey infrastructure, and increase urban resilience against climate-driven flooding.

This report uses the Sustainable Asset Valuation (SAVi) methodology to evaluate the economic, social, and environmental benefits of restoring 579 hectares of the Rocuant–Andalién coastal wetland system in Chile's Biobío region. The analysis demonstrates that nature-based infrastructure (NBI) is economically viable across all modelled scenarios, providing significant returns through avoided flood damage, carbon storage, and social value.

This report provides an economic valuation of the new phase of the "Freetown the Treetown" initiative in Freetown, Sierra Leone, which uses nature-based infrastructure (NBI) to combat deforestation and climate change. The assessment evaluates two planting scenarios to determine the societal and financial returns of reforestation efforts aimed at reducing natural hazards and carbon emissions.

This briefing by the Africa Policy Research Institute (APRI) examines the status of climate change adaptation in Ghana, focusing on the opportunities and barriers to locally-led adaptation. Based on case studies across three ecological zones, the analysis highlights that while local communities are actively employing indigenous knowledge and innovative practices to build resilience, they are constrained by limited financial resources, inadequate institutional support, and poor coordination between national and sectoral strategies.

This briefing transcript features Mary Austerman of New York Sea Grant discussing the integration of weather and social science data to support participatory planning and coastal resilience in New York's Great Lakes region, specifically focusing on Lake Ontario.

This policy brief examines the Tanzania Urban Resilience Programme (TURP) and its efforts to build climate resilience in the Msimbazi Basin of Dar es Salaam. It highlights the shift from hard-engineering to nature-based solutions, the importance of stakeholder engagement, and strategic project framing to secure diverse funding sources.

This case study, part of the Baltic COMPASS project, analyzes flood risk and river basin management in Kristianstad, Sweden, identifying significant barriers to adaptive river management, including a lack of cross-sectoral integration and the absence of a river basin-wide governance structure for water flows.

This briefing describes how the Western Province of Sri Lanka is integrating urban and peri-urban agriculture and forestry into its climate change adaptation strategies to mitigate flood risks, reduce greenhouse gas emissions, and improve food security.

This case study describes how the Town of Canmore, Alberta, developed a Climate Resilience Action Plan in 2016 using the Climate Resilience Express (CRE) tool developed by All One Sky (AOS). The process involved identifying climate risks and opportunities through stakeholder workshops and bilateral meetings, leading to specific adaptation strategies for forest fires, Bow River flooding, and mountain creek flooding.

The Aqueduct Floods Cost-Benefit Analyzer is a tool developed by the World Resources Institute to assess the economic feasibility of investing in flood protection infrastructure, specifically dikes and levees, to protect urban areas from riverine floods.
