    Description:

    The Methodological Guide: Canadian System of Environmental-Economic Accounting provides readers with information on environmental-economic accounts at Statistics Canada. It provides links to produced data and publications and describes the concepts, sources, and methods used to compile them. Topics include ecosystem accounting, asset accounts (natural resources in physical and monetary terms), physical flow accounts (energy and water use, and waste and greenhouse gas emissions), environmental activity statistics (expenditures on environmental protection), and the applications and extensions of those accounts (attribution of physical flows to final demand and intensity measures).

    This user's guide has been developed by the Environmental Statistics Program to facilitate access to environmental-economic accounting information throughout Statistics Canada and to explain its linkage with international standards, the United Nations System of Environmental-Economic Accounting. This guide is continually being updated to maintain its relevance.

  • Surveys and statistical programs – Documentation: 16-001-M2009008
    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:

    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.
