This report presents a Sustainable Asset Valuation (SAVi) analysis comparing a conventional mass tourism scenario against a sustainable tourism pathway for Geopark Teskei in Kyrgyzstan over a 25-year period.

An economic valuation by the Nature-Based Infrastructure Global Resource Centre finds that investing in the rehabilitation of Sherwan Hill Adventure Park in Abbottabad, Pakistan, yields a return of USD 2.49 for every USD 1 spent over 30 years. The project, part of the Khyber Pakhtunkhwa Cities Improvement Project, aims to combat the effects of rapid urbanization (3.5% annual growth) and climate change—including flash floods, landslides, and the urban heat island effect—by expanding green infrastructure to improve public health and climate resilience.

This report by the Nature-Based Infrastructure Global Resource Centre evaluates the economic and environmental benefits of nature-based infrastructure (NBI) within the Integrated Natural Resources Management Programme (INReMP) in Kenya, focusing on water scarcity and sustainable agriculture.

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).

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 presents an integrated cost-benefit analysis by the NBI Global Resource Centre on the use of nature-based infrastructure (NBI) to combat land degradation and desertification in Burkina Faso, highlighting significant economic returns and socioeconomic benefits.

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 commentary by the International Institute for Sustainable Development (IISD) argues that nature-based infrastructure (NBI) can be a powerful tool for women's empowerment and climate adaptation. It highlights how women, particularly in the Global South, are disproportionately affected by climate change due to their reliance on natural resources and systemic barriers to resource control. The document advocates for gender-responsive NBI projects and valuations to ensure equitable benefits and leadership roles for women.

This report applies the Sustainable Asset Valuation (SAVi) methodology to Stephenfield Reservoir and Pelly's Lake in Manitoba, Canada. It evaluates the economic value of ecosystem services—such as flood control, carbon offsets, and water supply—by comparing them to the cost of equivalent grey infrastructure, arguing that such valuations can help policy-makers justify the conservation of natural ecosystems as critical buffers against climate change.

This report applies the Sustainable Asset Valuation (SAVi) methodology to two infrastructure assets in Manitoba, Canada: Stephenfield Reservoir (a built asset) and Pelly’s Lake (a natural wetland). The study quantifies the economic value of the ecosystem and infrastructure services they provide and compares these to the costs of replacing those services with grey infrastructure. The findings demonstrate that both natural and naturalized built assets are significantly more cost-effective than traditional grey infrastructure for water storage, irrigation, and nutrient removal.

This fact sheet describes the application of the Sustainable Asset Valuation (SAVi) methodology to two assets in Manitoba, Canada: Stephenfield Reservoir and Pelly's Lake. The assessment compares the costs of maintaining these natural and built assets against the capital and operational costs of replacing their services with 'grey' (engineered) infrastructure, while simulating baseline and climate change scenarios from 2019 to 2050.
