There is growing momentum across the Canadian Prairies (Alberta, Saskatchewan, and  Manitoba) to implement natural infrastructure as an approach to help meet water infrastructure  needs (Méthot et al., 2023). Natural infrastructure is a way to plan and work with nature to  meet infrastructure needs—for example, water treatment, flood protection, and water supply— while providing a range of social, economic, and environmental benefits.The scope of the natural infrastructure sector is broad, involving activities to conserve and  restore ecosystems (e.g., wetlands, riparian areas) and to actively build with nature (e.g., green  roofs) in urban and rural areas. This study investigates two questions:  1. How much does the natural infrastructure sector, broadly defined, contribute to economic  activity across the Canadian Prairies?2. How might public investment drive future growth in the natural infrastructure sector,  contributing to jobs and GDP? Based on a combination of economic analysis, desktop research, and key informant interviews, the  study identifies and classifies industries relevant to natural infrastructure and estimates how the  natural infrastructure sector is creating jobs and boosting GDP across the three Prairie provinces.
