Integrated Water Resources Management (IWRM) in Canada

The report examines the integration of agricultural practices into Integrated Water Resources Management (IWRM) frameworks across Canada and internationally. It identifies the watershed as the appropriate planning unit and highlights the critical role of private agricultural landowners in achieving environmental sustainability. Through an inventory of provincial initiatives and global case studies, the document analyzes the social, economic, and technical drivers of success, emphasizing the need for multi-stakeholder collaboration, long-term monitoring, and financial incentives for beneficial management practices (BMPs). It concludes with recommendations for Agriculture and Agri-Food Canada (AAFC) to coordinate federal efforts and increase support for watershed-scale agricultural sustainability.

• Canada possesses 7 per cent of the world's fresh water and 25 per cent of global wetlands, yet faces regional water shortages, floods, and quality issues exacerbated by climate change.
• Agricultural watersheds are particularly vulnerable to climate change because they are more dependent on the hydrologic cycle than non-agriculture-use watersheds.
• The primary institutional challenge for IWRM in Canada and globally is that administrative decision-making boundaries often do not align with natural watershed boundaries.
• In Alberta, the 'Cows and Fish' program is highlighted as a highly successful agricultural extension initiative for improving riparian health through producer-led leadership.
• Saskatchewan's IWRM approach utilizes a science-based watershed health indicator framework to prioritize watersheds for action under its Safe Drinking Water Strategy.
• Ontario's Conservation Authorities (CAs) are described as the oldest and most advanced IWRM organizations in Canada, with the Grand River Conservation Authority (GRCA) being a leading entity in reducing flood damage and improving water quality.
• Québec's water governance reform centers on Watershed-Based Management (WBM) through 33 priority watersheds managed by 'Organisations de Bassin Versant' (OBVs).
• The Tobacco Creek Model Watershed in Manitoba serves as a 'living watershed laboratory' that integrates scientific monitoring with the economic priority of maintaining net farm income.
• International case studies, such as the Catskills/Delaware Watersheds in New York City, demonstrate that paying farmers for ecosystem services is a cost-effective alternative to building expensive water treatment infrastructure.
• Successful IWRM requires 'horizontal integration' across different government ministries (e.g., finance, agriculture, health, and environment) and 'vertical integration' across different levels of authority.
• A critical technical requirement for effective IWRM is the establishment of long-term, robust monitoring programs to provide a science-based measurement of watershed health over time.
• The report recommends that Agriculture and Agri-Food Canada (AAFC) establish a federal interdepartmental IWRM team to coordinate participation in local and regional watershed initiatives.
