An Application of the Sustainable Asset Valuation (SAVi) Methodology to Pelly's Lake and Stephenfield Reservoir, Manitoba, Canada

The SAVi assessment demonstrates that natural and nature-based infrastructure in Manitoba provide high economic value and cost-effective alternatives to built assets. For Stephenfield Reservoir, the cumulative discounted value of agriculture-related services is CAD 6.07 billion by 2050, while replacing it with grey infrastructure would require CAD 5.3 million in capital costs. Pelly's Lake provides cumulative discounted ecosystem services valued at approximately CAD 60 million between 2019 and 2050, primarily driven by nutrient removal and carbon sequestration.

• Stephenfield Reservoir provides highly cost-effective irrigation and water storage services, with a cumulative discounted value of CAD 6.07 billion by 2050 against operating and management costs of CAD 256,000.
• Replacing Stephenfield Reservoir with grey infrastructure would be significantly more expensive, requiring CAD 5.3 million in capital costs and approximately CAD 300,000 in annual maintenance, compared to the current reservoir maintenance cost of CAD 256,000.
• Pelly's Lake provides ecosystem and infrastructure services with a cumulative discounted valuation of approximately CAD 60 million from 2019 to 2050, with the highest values attributed to nutrient removal and carbon sequestration.
• Under climate change scenarios, the value of flood protection provided by Pelly's Lake increases significantly, with the discounted value rising by 43.22% compared to the baseline.
