With the advent\nof climate change, natural ecosystems are also critical, as they serve as\nbuffers against catastrophic weather and the resulting floods, droughts,\nlandslides and forest fires. However, what is the financial value of these\n\u201cservices\u201d? Also, if policy-makers, investors and citizens were better informed\non these services and their values, would it support the conservation and\nregeneration of natural habitats?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This SAVi\nassessment responds to these questions. It gives a valuation of the ecosystem\nservices provided by examples of built and natural infrastructure:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Stephenfield Reservoir is a civil engineered\nreservoir that was built for irrigation and domestic water supply; and <\/li><li>Pelly\u2019s Lake is a natural wetland that is being\nactively managed for flood control. Their added benefits are related to\nimproved habitat and biodiversity, groundwater recharge, nutrient and sediment\nsequestration, carbon offsets and various economic uses of the biomass (plant\nmaterial). From there, the assessment values the cost of the grey\ninfrastructure that would be needed to provide the same level of service. <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This\nassessment was conducted in close collaboration with LaSalle Redboine\nConservation District, Manitoba Sustainable Development and Manitoba\nInfrastructure. We sourced data from public sources as well as from these\norganizations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SAVi Results: Stephenfield Reservoir<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The SAVi tool\nanalysis indicates that the real value of Stephenfield Reservoir is that it\nprovides extremely cost-effective irrigation and water storage services. The\noperating and management costs of the reservoir are CAD 256,000, while the\nirrigation and water storage services it provides enable economic activity that\nadds up to a cumulative discounted value of CAD 6.07 billion by 2050 (Table 2).\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SAVi analysis also highlights that, if the Province of Manitoba were to build grey infrastructure to provide the same water storage and irrigation services that are currently being provided by Stephenfield Reservoir, the capital cost required would be CAD 5.3 million. The cost of maintaining the reservoir by way of comparison is CAD 256,000.<\/p>\n\n\n\n<div style=\"height:54px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-media-text alignwide\" style=\"grid-template-columns:60% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"316\" src=\"https:\/\/iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-1-1.png\" alt=\"\" class=\"wp-image-2043\" srcset=\"https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-1-1.png 500w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-1-1-300x190.png 300w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-1-1-150x95.png 150w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-1-1-450x284.png 450w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>Figure 1.<\/strong> Comparing the cost of Stephenfield Reservoir with new grey infrastructure that would provide the same volume of services, 2019 and 2050 (all costs are cumulative)\n\n<\/p>\n<\/div><\/div>\n\n\n\n<div style=\"height:54px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-media-text alignwide\" style=\"grid-template-columns:60% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"491\" src=\"https:\/\/iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-2.png\" alt=\"\" class=\"wp-image-2044\" srcset=\"https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-2.png 500w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-2-300x295.png 300w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-2-150x147.png 150w, https:\/\/www.iisd.org\/savi\/wp-content\/uploads\/2019\/06\/fig-2-450x442.png 450w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>Figure 2.<\/strong> SAVi valuation on the costs, benefits and avoided costs of Stephenfield Reservoir, 2019 to 2050\n\n<\/p>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>SAVi Results: Pelly\u2019s Lake<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The real benefits of Pelly\u2019s Lake are in the\necosystems and infrastructure services that it provides: representing\ncumulative discounted valuation of approximately CAD 60 million between 2019\nand 2050.
