The AquaHacking Lake Winnipeg 2020 Challenge, hosted by the International Institute for Sustainable Development (IISD) and Aqua Forum, engaged 472 youth and 19 teams to address critical water issues. Five finalist teams were awarded seed funding and incubation spots at North Forge Technology Exchange for solutions targeting microplastics, agricultural runoff, eutrophication, and drinking water quality in remote communities.

The document describes a pioneered practice of harvesting cattails and other plants from water retention areas and drainage ditches to remove phosphorus, improve habitat, and create biomass for energy and bioproducts. It highlights the role of this 'unconventional' waste biomass in a circular economy by recycling nutrients and sequestering carbon in soil. The review specifically looks at global carbon markets since the Kyoto Protocol and Paris Agreement to find verification methodologies suitable for bioeconomy projects in Manitoba and Canada.

The report evaluates floating treatment wetlands (FTWs) as a nature-based solution for eutrophication in shallow lakes. Through primary research at the IISD-Experimental Lakes Area (IISD-ELA) and a case study of Pelican Lake, Manitoba, the study demonstrates that FTWs—particularly those using cattails—effectively sequester phosphorus and nitrogen. While plant biomass contributes to nutrient removal, the report emphasizes that the microbial biofilm on roots provides up to 80% of the total treatment. For Pelican Lake, the study estimates that 5% surface coverage could reduce total phosphorus levels by 10% to 50%, though FTWs must be combined with watershed-level strategies to meet provincial water quality standards.

Beardy’s and Okemasis’ Cree Nation used the Pathways to Climate Change Resilience Guidebook to identify climate risks and prioritize adaptation actions following repeat flooding in 2005, 2007, and 2011. The process integrated Traditional Knowledge to engage community members and leveraged a network of partners to secure funding for infrastructure improvements, such as expanded drainage ditches and culverts, and drinking water quality research.

The report details IISD's Bioeconomy project (2017-2019) focusing on harvesting unconventional biomass from water retention sites and roadside ditches in Manitoba. It argues that this practice removes phosphorus to protect Lake Winnipeg, improves habitat health, and provides a low-carbon alternative to fossil fuels or a means of soil carbon sequestration. The document analyzes harvesting methods, the shift from bioenergy to livestock bedding and compost, and evaluates global and North American carbon market verification methodologies to identify frameworks suitable for these watershed management activities.

The report identifies that Ontario provided nearly CAD 700 million in public subsidies for fossil fuel consumption in 2018/19. These primarily consist of tax exemptions for aviation, railway, and agricultural fuels, as well as direct spending on natural gas infrastructure. The authors argue that these subsidies distort the market and hinder climate goals, recommending a transparent provincial self-review to identify more sustainable alternatives for energy affordability and industry competitiveness.

The document describes a Sustainable Asset Valuation (SAVi) assessment of two sites in Manitoba: the civil engineered Stephenfield Reservoir and the natural wetland Pelly's Lake. It aims to quantify the financial value of ecosystem services—such as flood protection, water storage, and carbon offsets—to inform policy-makers and investors on the benefits of maintaining natural and built infrastructure over traditional grey infrastructure.

This briefing describes the use of open spatial data to identify environmental 'hotspots' in Manitoba to optimize the allocation of limited resources for water quality, sustainable agriculture, and carbon sequestration.

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.

The briefing identifies three specific water-quality hotspots in Manitoba based on 2016 Census of Agriculture data: the Southwest Red River Valley (high fertilizer application), Southwestern Manitoba (high conservation tillage), and the Southeast Red River Valley (high non-incorporated manure application). It argues that spatial targeting of natural infrastructure, such as engineered wetlands, and beneficial management practices can maximize the efficiency of public investments to reduce nutrient runoff into Lake Winnipeg.

The report details Canada's greenhouse gas emissions from 1990 to 2016, highlighting that while overall emissions grew nearly 17%, the oil and gas and transportation sectors were the primary drivers. It examines the Pan-Canadian Framework on Clean Growth and Climate Change and provides a detailed breakdown of emissions by province and territory, noting significant per capita disparities between jurisdictions like Alberta and Quebec.

The document outlines the climate-related risks facing health care facilities (HCFs) and provides a framework for mitigation and adaptation. It highlights that 90% of health care life-cycle GHG emissions in Canada are generated upstream in the supply chain, with pharmaceuticals and hospitals being major contributors. The guide recommends using resiliency checklists, vulnerability assessments, and sustainable procurement to reduce environmental footprints. It also discusses specific interventions in energy efficiency, transportation (including telemedicine), and the reduction of potent inhalation anesthetic gases.

The document details how climate change affects Canadian health through extreme heat, air pollution, UV radiation, and the spread of vector-borne and water-borne diseases. It emphasizes that marginalized populations, including Indigenous peoples and low-income individuals, face disproportionate risks. Regional analyses highlight specific threats such as melting permafrost in the North, hurricanes in Atlantic Canada, and increased drought in the Prairies.

The document outlines adaptation strategies for various climate-related health risks in Canada, including extreme temperature events, flooding, wildfires, food insecurity, vector-borne diseases, and water quality issues. It provides specific examples of municipal actions—such as Toronto's green roof bylaws and Vancouver's warming centres—and offers actionable tips for health professionals to support vulnerable patients and advocate for resilient community policies.

The document is a comprehensive guide for healthcare professionals to address climate change. It covers the science of climate change, its global and Canadian health impacts, greenhouse gas (GHG) emission trends in Canada, and practical solutions. It emphasizes 'co-benefits'—where climate actions like promoting plant-based diets or active transport immediately improve public health. The guide provides specific strategies for making healthcare facilities more resilient and sustainable, such as reducing the carbon footprint of anesthesia and supply chains, and offers a framework for community-level adaptation and professional advocacy.

The Lake Winnipeg Foundation and the International Institute for Sustainable Development argue that phosphorus from undertreated sewage is driving toxic algae blooms in Lake Winnipeg. They identify the North End Water Pollution Control Centre (NEWPCC) as the largest point source of phosphorus for the lake and the fourth largest phosphorus polluter among Canadian wastewater facilities. While a full plant upgrade is planned, it is estimated to cost $1.8 billion and will not begin for at least 10 years. The authors propose a $5 million interim retrofit that could be implemented quickly to reduce the plant's phosphorus contribution by 70%.

The Canadian Association of Physicians for the Environment (CAPE) submitted a brief to the City of Edmonton arguing that the current Integrated Pest Management (IPM) policy fails to adequately address human health risks. CAPE highlights that children are particularly vulnerable to pesticide exposure, which is linked to developmental deficits and childhood cancers, while adults face risks of Parkinson's disease and various cancers. The document criticizes Health Canada's Pest Management Regulatory Agency (PMRA) for relying on industry-supplied data and failing to conduct timely re-evaluations of registered pesticides. CAPE recommends that Edmonton formalize a policy to eliminate routine toxic pesticide use in city-managed parks and for mosquito control, and implement a bylaw restricting non-essential pesticide use on residential and private lawns.

The report outlines the value of natural infrastructure (NI) in Canada for climate adaptation, specifically for flood and drought mitigation. It identifies significant barriers in federal funding programs, such as the Investing in Canada Infrastructure Program (ICIP) and the Disaster Mitigation and Adaptation Fund (DMAF), including high funding thresholds and restrictions on private land eligibility. The document explores innovative financing mechanisms like green bonds and insurance-linked resilience bonds, while emphasizing the need for natural asset accounting in public sector financial statements to incentivize municipal protection of NI.

The research analyzes six international water quality offset programs to determine how regulated dischargers can offset excess pollutant loads against reductions made elsewhere in a watershed. The study specifically aims to provide design and implementation lessons for Manitoba, where over 200 wastewater treatment facilities contribute to the eutrophication of Lake Winnipeg.

The study reviewed 30 local plans in Manitoba and found that very few explicitly address climate change adaptation: only five development plans and two integrated watershed management plans, with no emergency plans including such considerations. To close these gaps, the report recommends that the Province of Manitoba collaborate with the Canadian Centre for Climate Services and the Prairie Climate Centre to provide municipalities and watershed districts with local climate projections and updated planning templates.
