Hydrology and water resources in Canadian geography

Academic research on water by Canadian geographers encompasses both the physical and the social sciences. While this may provide for an integrated approach to water, there is limited engagement between the hydrologists who study the details of the hydrological cycle and those who study water resources and governance. This paper reviews the current state of water research in Canadian geography departments and possible emergent areas of research in the coming decade. As an overview, interjected with points of contention, future discourses on the subject may be encouraged.     

Spatial‐temporal patterns of snow cover in western Canada

Snow cover is often measured as snow‐water equivalent (SWE), which refers to the amount of water stored in a snow pack that would be available upon melting. Snow cover and SWE represent a source of local snow‐melt release, and are sensitive to regional and global atmospheric circulation, and changes in climate. Monitoring SWE using satellite‐based passive microwave radiometry has provided nearly three decades of continuous data for North America. The availability of spatially and temporally extensive SWE data enables a better understanding of the nature of space‐time trends in snow cover, changes in these trends and linking these trends to underlying landscape and terrain characteristics. To address these interests, we quantify the spatial pattern of SWE by applying a local measure of spatial autocorrelation to 25 years of mean February SWE derived from passive microwave retrievals. Using a method for characterizing the temporal trends in the spatial pattern of SWE, temporal trends and variability in spatial autocorrelation are quantified. Results indicate that within the Canadian Prairies, extreme values of SWE are becoming more spatially coherent, with potential impacts on water availability, and hazards such as flooding. These results also highlight the need for Canadian ecological management units that consider winter conditions.     

Protecting aquatic ecosystems in heavily allocated river systems: the case of the Oldman River Basin,Alberta

Initiatives aimed at protecting aquatic ecosystems often prove difficult to implement—particularly in water‐stressed, semi‐arid regions where the demand for water for human consumption is high. This article reports on an investigation of the factors that shaped the development and implementation of policies for aquatic ecosystem protection in the Oldman River Basin (ORB), a crucial watershed in semi‐arid southern Alberta. The analysis reveals critical cultural and historical considerations that confront those attempting to protect and restore aquatic ecosystems in the ORB and highlights specific factors that influence implementation of measures to protect it. In addition to the most basic consideration—demand for water exceeds supplies—eight specific factors that influenced aquatic ecosystem protection in this region are identified and evaluated. These include (1) clarity of actors’ roles/ jurisdictional responsibilities; (2) communication; (3) definition of key terms; (4) funding and organizational capacity; (5) leadership; (6) legal standing; (7) data and monitoring; and (8) public education. We argue that while these factors are important, critical cultural and historical considerations that influence water policy in the province also must be addressed in any efforts to protect aquatic ecosystems in southern Alberta.     

The politics of water security in southern Saskatchewan

This paper examines long-term water and resource management in Saskatchewan. Agriculture has long sustained Saskatchewan's economy, but the province experienced a resource boom in oil and potash in the 2008–2015 time period. What potential water-related risks are posed by oil and potash? And is the province able to balance the short-term economic gains of these developments with the long-term goal of water security? The research is based on interviews with policy elites in the province of Saskatchewan and argues that four factors explain why the government continues to favour industry over water security: low-issue salience, economic and political interest, ideology, and political culture.
