Seal River Watershed: The case for conservation
The Seal River Watershed in northern Manitoba is a 50,000 km2 area that is 99.97% intact and serves as one of Canada's largest free-flowing drainage basins. The report highlights its critical role in biodiversity, storing 1.7 billion tonnes of carbon and supporting species at risk such as polar bears and barren-ground caribou. Economically, the watershed provides at least CAD 214 million in annual ecosystem goods and services (EGS), including ecotourism and caribou harvesting, while the stored carbon is valued at CAD 314.5 billion. The document advocates for the creation of an Indigenous Protected Area (IPA) led by the Sayisi Dene, Northlands Denesuline, Barren Lands First Nation, and O-Pipon-Na-Piwin Cree Nation to prevent threats from mining, hydroelectricity, and road development. It suggests the Manitoba government implement interim protections, establish a feasibility committee, and provide technical support for Indigenous Guardians programs.

WASTE MARKET INTELLIGENCE REPORT
The 2022 Waste Market Intelligence Report by GreenCape identifies significant value-add potential in the waste sectors of Cape Town and the Western Cape, estimating a total potential of R320 million to R5 billion annually. The report highlights organic waste as the greatest opportunity, driven by provincial landfill restrictions aiming for 100% diversion by 2027 and the City of Cape Town's (CCT) goal of 100% organic waste diversion by 2027. Key drivers include rising landfill gate fees—with the CCT having the highest metropolitan fee in South Africa at R557 per tonne (excl. VAT)—and the implementation of mandatory Extended Producer Responsibility (EPR) for paper, packaging, electronics, and lighting as of November 2021. The report details specific opportunities in black soldier fly larvae production, biogas, and composting, while noting barriers such as inadequate source separation and the lack of reliable e-waste data. It also outlines the CCT's planned investments in four new material recovery facilities (MRFs) and its strategic shift toward a circular waste economy.

Sustainable Asset Valuation (SAVi) of Senegal’s Saloum Delta
The report uses the Sustainable Asset Valuation (SAVi) tool to quantify the economic importance of the Saloum Delta's wetlands and mangroves. It compares a business-as-usual (BAU) scenario against interventions such as organic agriculture, mangrove reforestation, road construction, solar cookstoves, and oil extraction. The analysis highlights a significant trade-off: while oil extraction generates massive near-term revenues, it causes substantial losses in ecosystem services. Conversely, nature-based interventions like mangrove restoration and organic agriculture provide long-term economic gains through enhanced ecosystem performance and labour income. The report also proposes blended finance strategies, including carbon offsets and impact bonds, to fund conservation.

An Application of the Sustainable Asset Valuation (SAVi) Methodology
The report demonstrates that the S’Ena Arrubia and Corru S’Ittiri-Marceddì-San Giovanni wetlands provide substantial economic value through ecosystem services and the support of local aquaculture, tourism, and agriculture. It finds that a 'continued degradation' scenario would lead to significant losses in labour income and ecosystem service value, while a circular business model for reusing livestock manure could generate net benefits of EUR 81.3 million for S’Ena Arrubia and EUR 124.2 million for Corru S’Ittiri-Marceddì-San Giovanni. The analysis argues that the cost of maintaining these wetlands is far lower than the cost of replacing their functions with built infrastructure.

Sustainable Asset Valuation (SAVi) of a Public Bicycle Sharing System in Dwarka, New Delhi, India: A focus on the environmental, social and economic impacts of non-motorized transport infrastructure
The report evaluates a planned public bicycle sharing (PBS) system in Dwarka, New Delhi, using the Sustainable Asset Valuation (SAVi) methodology. While a conventional cost-benefit analysis shows the system is financially deficient, the integrated SAVi analysis reveals positive net values across all demand scenarios. The most significant benefits are derived from time saved, reduced air pollution costs, and increased retail and property values. Over a 20-year period, discounted net benefits are estimated between INR 3.14 billion (~USD 44.4 million) under conservative assumptions and INR 12.19 billion (~USD 172.3 million) in a high-demand scenario. The findings suggest the PBS system supports the Delhi Master Plan 2021 and justifies investment in bicycle and road safety infrastructure.

An Application of the Sustainable Asset Valuation (SAVi) Methodology to Pelly's Lake and Stephenfield Reservoir, Manitoba, Canada
The report evaluates the financial value of nature-based infrastructure in Manitoba, Canada, specifically Pelly's Lake (a natural wetland) and Stephenfield Reservoir (a naturalized built reservoir). Using the SAVi methodology, it calculates the value of services such as irrigation, water storage, nutrient removal, and carbon sequestration. The analysis finds that both assets are significantly more cost-effective than equivalent grey infrastructure. For Stephenfield Reservoir, the cumulative discounted value of enabled economic activity is CAD 6.07 billion by 2050, while replacing its services with grey infrastructure would cost CAD 5.33 million in capital. For Pelly's Lake, ecosystem services are valued at approximately CAD 60 million, whereas equivalent grey infrastructure would cost CAD 36.99 million. The report argues that maintaining these natural assets optimizes value for money and supports climate adaptation against floods and droughts.

Sustainable Asset Valuation Tool
The document defines natural infrastructure (NI) as ecosystems providing infrastructure services and distinguishes between 'natural' (e.g., wetlands) and 'green-grey' (e.g., permeable pavements) types. It argues that NI is generally more cost-effective than grey infrastructure, offering co-benefits in land security, climate regulation, and water security. However, adoption is hindered by high transaction costs, long time horizons for full capacity, and a lack of standardized quantitative evaluation tools. The report provides specific cost data for artificial wetlands and restoration projects, while identifying policy interventions—such as rating systems and market instruments—to incentivize investment.
