    Description:

    Households in Canadian municipalities often have options when choosing the type of water they drink at home and whether they treat it prior to drinking it. The reasons why they might choose to treat their water could be aesthetic or there might have been problems in the past that are influencing their decisions today. Using data from the 2007 Households and the Environment Survey, the author explores some of the factors governing these decisions for households in a selection of Canadian municipalities.

    Description:

    The Lower Mainland ecoregion profile is the first in an upcoming series of ecoregion profiles. The information presented includes a brief description of the physical setting, a snapshot of land cover and use as well as selected statistics on the changing socio-economy in the region. This ecoregion will be the site for many of the activities associated with the 2010 Vancouver Winter Olympics.

    Description:

    Energy use is one of the primary contributors to environmental degradation and climate change. This article provides a profile of the Canadian manufacturing industry and the investments made in energy-related processes and technologies in 2006. These investments either reduced the amount of energy used for a process, or lowered the amount of greenhouse gas emissions and air pollutants produced through the production and use of energy.

    Description:

    Water is essential for crop production, whether it is provided by rain or irrigation. Although relatively few farms in Canada irrigate, this use of water can represent a significant portion of water use in some areas of the country. This article presents information on the use of irrigation in 2007.

    Description:

    In 2008, Statistics Canada conducted the first Agricultural Water Use Survey. This pilot survey is part of the Canadian Environment Sustainability Indicators initiative and collects information on volumes of water used for irrigation, irrigated areas, irrigation practices and the quality of water used for agricultural purposes. This technical paper describes the methodology used for the pilot survey and includes recommendations for future cycles of the survey. The validation process seems to indicate that the method used to estimate the volumes of water used and the irrigated areas calculated underestimates the results. The report gives recommendations to minimize this bias in the next iterations of the survey. First, it is recommended to simplify the level of information collected by the survey; to review the sampling methodology; and to examine other means of collecting information on volumes of water used for irrigation. This pilot version of the survey remains a reliable source for consistent data on agricultural water use.

    Description:

    Canada's renewable water resources are mostly the result of rain and melted snow that flow over the ground, eventually reaching our rivers and lakes. This article describes the results of a new methodology producing consistent national estimates of Canada's total annual average water yield from 1971 to 2000.

    Description:

    Using data from Statistics Canada's Survey of Environmental Protection Expenditures and Annual Survey of Manufacturers and Logging, as well as data derived from Environment Canada's National Pollution Release Inventory, this study examines environmental expenditures in the manufacturing sector.

    Description:

    The feature article, Food in Canada, begins with a brief historical perspective on fishing and farming in Canada and moves on to explore the impact of the food system on the economy, environment and society. It illustrates how the contribution of the food system to gross domestic product and employment has shifted over the past forty years, and investigates the impact of primary food production on land, water, air and climate. The article concludes with a characterization of what is on the Canadian table, and the greenhouse gas emissions and energy-use associated with household food purchases.

    Description:

    In this paper, we present the methodology developed by Statistics Canada to calculate the average annual water yield for Canada. Water yield, for the purposes of this paper, is defined as the amount of freshwater derived from unregulated flow (m3 s-1) measurements for a given geographic area over a defined period of time. The methodology is applied to the 1971 to 2000 time period.

    This research was conducted to fill data gaps in Statistics Canada's water statistics program. These gaps exist because estimates of freshwater flow for Canada have not been calculated regularly and have been produced using a variety of methods that do not necessarily generate comparable results. The methodology developed in this study produced results that are coherent through space and time. These results will be used in the future to investigate changes in water yield on a more disaggregated basis.

    To achieve the water yield estimate a database of natural streamflow observations from 1971 to 2000 was compiled. The streamflow values were then converted to a runoff depth and interpolated using ordinary kriging to produce spatial estimates of runoff. The spatial estimates were then scaled to create a National estimate of water yield as a thirty-year average. The methodology and results were then validated using a stability analysis and several techniques involving uncertainty. The result of the methodology indicates that the thirty-year average water yield for Canada is 3435 km3.

    Description:

    Remote Sensing and Geospatial Analysis (RSGA) of the Agriculture Division prepared a series of maps and statistics that show the progression of the 2009 Red River valley flood in Manitoba for the spring of 2009. Starting with an image acquired on March 31, the maps were produced from the analysis of Radarsat-2 satellite image data integrated with 2006 Census of Agriculture data and census geography boundary files. From this analysis, the total area of flooded agriculture land and the number of farmers affected were calculated. A comparison is made with the 1997 flood that occurred in the same region.

    This bulletin's analysis focuses on the effect of "rurality" in determining: 1) water consumption flows at the municipal level; and 2) water quality perception of a household, as proxied by the water treatment choice of a household.
