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.

The Nature-Based Infrastructure (NBI) Global Resource Centre conducted a cost-benefit analysis of ecosystem-based adaptation in Costa Rica's Reventazón River basin to stabilize hydrology and secure water and energy supplies.

This report by the Nature-Based Infrastructure Global Resource Centre provides an integrated cost-benefit analysis of the 'Bring Back Our Trees' reforestation project in Kasese, Uganda, demonstrating the economic and environmental benefits of nature-based infrastructure (NBI) in mitigating climate-related flooding and landslides.

This technical report provides a Sustainable Asset Valuation (SAVi) of the proposed rehabilitation of the Tirana–Durres railway in Albania. Using a systemic approach, the assessment compares a business-as-usual scenario with a railway scenario to quantify economic, social, and environmental impacts over a 30-year period (2023–2053). The analysis demonstrates that while the project is not economically viable under conventional cost-benefit analysis, it is highly profitable when integrating non-tangible societal benefits.

This report presents a Sustainable Asset Valuation (SAVi) assessment of a proposed Bus Rapid Transit (BRT) system in Bandung, Indonesia. The analysis compares a baseline scenario with a 'current BRT' scenario and a 'high-ambition BRT' scenario over a 28-year period (2022–2050). The assessment demonstrates that while the project may not be economically viable under conventional benefit-cost ratios (BCR) that only consider tangible financial returns, it is highly profitable from a societal perspective when integrating environmental, social, and economic externalities.

This report presents a sustainable asset valuation (SAVi) assessment of mangrove restoration in the Mallorquín Swamp in Barranquilla, Colombia, comparing nature-based infrastructure (NBI) against grey infrastructure alternatives over a 20-year period.

This executive summary presents a Sustainable Asset Valuation (SAVi) assessment of the full electrification of the public bus fleet in Ulaanbaatar, Mongolia, by 2050. The analysis compares a baseline electrification scenario against two scenarios involving a modal shift from private vehicles to public transport, quantifying the socio-economic and environmental benefits over a 25-year period (2025–2050).

A fact sheet detailing the Sustainable Asset Valuation (SAVi) assessment of nature-based solutions (NbS) implemented by SUNCASA in Dire Dawa, Ethiopia, projecting significant economic and environmental benefits between 2025 and 2050.

This fact sheet presents a Sustainable Asset Valuation (SAVi) assessment of nature-based solutions (NbS) implemented by SUNCASA in Dire Dawa, Ethiopia, projecting economic, social, and environmental benefits between 2025 and 2050.

This executive summary presents a Sustainable Asset Valuation (SAVi) assessment of a proposed mass rapid transit (MRT) system in Pampanga, Philippines. The assessment, conducted in collaboration with the National Economic and Development Authority (NEDA), compares traditional financial valuations with a sustainable approach that accounts for socio-economic and environmental externalities over a 30-year period from 2023 to 2053.

This executive summary presents a Sustainable Asset Valuation (SAVi) for transport and building infrastructure along the Shymkent–Tashkent–Khujand economic corridor. The assessment compares traditional financial metrics with a sustainable benefit-cost ratio (S-BCR) to demonstrate the socioeconomic value of expanding electrified rail and sustainable buildings over conventional options.

This executive summary presents a Sustainable Asset Valuation (SAVi) of the proposed rehabilitation of the Tirana-Durres railway in Albania and the creation of a new connection to Rinas International Airport. The assessment compares a scenario of railway improvement against a baseline of no action, concluding that while the project is not economically viable based on traditional financial metrics, it provides substantial societal, environmental, and economic benefits over a 30-year period.
