This report by the Nature-Based Infrastructure Global Resource Centre evaluates the cost-benefit ratio of implementing nature-based infrastructure (NBI) to mitigate flood risks in the Drakenstein Municipality of South Africa, specifically focusing on river restoration in the Berg River catchment.

The Nature-Based Infrastructure Global Resource Centre, in collaboration with UNEP and local stakeholders, conducted a cost-benefit analysis of nature-based infrastructure (NBI) and hybrid scenarios across 12,000 hectares in four districts of Ghana to mitigate extreme weather impacts under three climate scenarios (SSP1, SSP3, and SSP5).

This methodological note describes a Sustainable Asset Valuation (SAVi) assessment conducted by the International Institute for Sustainable Development (IISD) for a proposed mass rapid transit (MRT) system in Pampanga, Philippines. The document outlines the SAVi framework, which integrates system dynamics, multi-criteria analysis, and project finance modelling to evaluate the economic, social, and environmental impacts of the project compared to a 'no action' scenario.

This report provides a Sustainable Asset Valuation (SAVi) of Metro Line 1 in Bogota, Colombia, the country's first modern metro system. The assessment evaluates the economic, social, and environmental impacts of the fully electric and automated mass rapid transit (MRT) system, focusing on its ability to reduce congestion and increase employment access for a population exceeding 8 million.

This Sustainable Asset Valuation (SAVi) analyzes the economic, social, and environmental impacts of the second phase of the Faster Adoption and Manufacturing of Electric (& Hybrid) Vehicles (FAME II) policy in India, which utilizes a budget of INR 100 billion to subsidize the electrification of public and shared transportation.

This report provides a Sustainable Asset Valuation (SAVi) of an assisted natural regeneration (ANR) project covering 2,868 hectares in Sodo Woreda, Ethiopia, demonstrating that land restoration provides direct economic benefits to farmers and climate services.

This report details a Sustainable Asset Valuation (SAVi) assessment of peatland and mangrove restoration in Indonesia, specifically focusing on the Katingan peatlands and Belitung mangroves. It evaluates the societal benefits and costs of various policy and climate scenarios, concluding that sustainable management is cost-effective for climate mitigation and community support, provided that local communities have alternative income sources to avoid environmentally damaging activities.

This report details a Sustainable Asset Valuation (SAVi) assessment of wastewater treatment infrastructure options for the Hartenbos estuary in South Africa, evaluating their impact on water quality, nutrient loads, and potential for agricultural water reuse.

This report details a Sustainable Asset Valuation (SAVi) assessment of a tree-planting initiative in Addis Ababa, Ethiopia, concluding that nature-based infrastructure (NBI) provides greater societal value and climate resilience than grey infrastructure alternatives.

This report presents a Sustainable Asset Valuation (SAVi) of the Poçem and Kalivaç hydropower projects on the Vjosa River in Albania, concluding that these assets generate higher costs to the state, environment, and communities than they provide in benefits.

This report applies the Sustainable Asset Valuation (SAVi) methodology to a planned Public Bicycle Sharing (PBS) system in Dwarka, New Delhi. It argues that while conventional cost-benefit analyses show the system is financially deficient, an integrated analysis including environmental, social, and economic co-benefits demonstrates a positive net value across all demand scenarios.

This executive summary presents a Sustainable Asset Valuation (SAVi) of Metro Line 1 of the Metro de Bogota Mass Rapid Transit (MRT) system. The analysis compares traditional benefit-cost ratios with a sustainable BCR (S-BCR) that accounts for environmental, social, and economic externalities, concluding that the MRT system provides substantial monetary benefits and societal value over a project period from 2022 to 2058.

This executive summary presents a Sustainable Asset Valuation (SAVi) assessment of the proposed Uchkuduk-Kazakhstan Border Highway in Uzbekistan. The analysis compares traditional benefit-cost ratios with a sustainable approach that accounts for social and environmental externalities over a 30-year period from 2022 to 2052.
