"The Canadian Disaster Database (CDD) contains detailed disaster information on more than 1000 natural, technological and conflict events (excluding war) that have happened since 1900 at home or abroad and that have directly affected Canadians. The CDD tracks ""significant disaster events"" which conform to the Emergency Management Framework for Canada definition of a ""disaster"" and meet one or more of the following criteria: •10 or more people killed •100 or more people affected/injured/infected/evacuated or homeless •an appeal for national/international assistance •historical significance •significant damage/interruption of normal processes such that the community affected cannot recover on its own The database describes where and when a disaster occurred, the number of injuries, evacuations, and fatalities, as well as a rough estimate of the costs. As much as possible, the CDD contains primary data that is valid, current and supported by reliable and traceable sources, including federal institutions, provincial/territorial governments, non-governmental organizations and media sources. Data is updated and reviewed on a semi-annual basis"

L'écoumène national agricole comprend toutes les aires de diffusion où règne une activité agricole « importante », qui est déterminée d'après des indicateurs agricoles tels que le rapport entre la superficie des terres agricoles des fermes de recensement et la superficie totale des terres, ainsi que la valeur économique totale de la production agricole. Les variations régionales sont également prises en considération. L'écoumène est généralisé en vue de la production de cartes à petite échelle. Une version de l'écoumène agricole était générée à toutes les années de recensement (en format vectoriel à partir de 1986 et pour les années 1991, 1996, 2001, 2006, 2011 et 2016).

The national agricultural ecumene includes all dissemination areas with 'significant' agricultural activity. Agricultural indicators, such as the ratio of agricultural land on census farms relative to total land area, and total economic value of agricultural production, are used. Regional variations are also taken into account. The ecumene is generalized for small-scale mapping. A new version of the agricultural ecumene was generated every census years (2001, 2006, 2011). Previous versions are no longer available.

Cette carte illustre le ratio du prélèvement d’eau douce de surface à l’apport en eau pour le mois d’août 2013, sauf dans les régions de drainage 7, 8, 16, 17 et 18, pour lesquelles on utilise le ratio du prélèvement d’eau du mois d’août à l’apport en eau mensuel minimum à long terme. En ce qui concerne les prélèvements d’eau douce de surface, les données de l’Enquête sur les usines de traitement de l’eau potable de 2013 et de l’Enquête sur l’utilisation industrielle de l’eau de 2013 sont agrégées avec les estimations de l’utilisation de l’eau à des fins agricoles pour 2013, qui sont fondées sur les données de l’Enquête sur l’utilisation de l’eau à des fins agricoles et du rapport intitulé Alberta Irrigation Information. Les données sur l’eau utilisée par l’industrie pétrolière et gazière et les ménages ne provenant pas d’un fournisseur d’eau public sont également exclues.

Drought is a deficiency in precipitation over an extended period, usually a season or more, resulting in a water shortage that has adverse impacts on vegetation, animals and/or people. The Climate Moisture Index (CMI) was calculated as the difference between annual precipitation and potential evapotranspiration (PET) – the potential loss of water vapour from a landscape covered by vegetation. Positive CMI values indicate wet or moist conditions and show that precipitation is sufficient to sustain a closed-canopy forest. Negative CMI values indicate dry conditions that, at best, can support discontinuous parkland-type forests. The CMI is well suited to evaluating moisture conditions in dry regions such as the Prairie Provinces and has been used for other ecological studies. Mean annual potential evapotranspiration (PET) was estimated for 30-year periods using the modified Penman-Monteith formulation of Hogg (1997), based on monthly 10-km gridded temperature data. Data shown on maps are 30-year averages. Historical values of CMI (1981-2010) were created by averaging annual CMI calculated from interpolated monthly temperature and precipitation data produced from climate station records. Future values of CMI were projected from downscaled monthly values of temperature and precipitation simulated using the Canadian Earth System Model version 2 (CanESM2) for multiple RCP radiative forcing scenarios. Multiple layers are provided: Climate moisture indexes are shown across Canada for a reference period from 1981-2010. Future projections using RCP 8.5 are given for three different time periods: 2011-2040; 2041-2070; 2071-2100. Future projection using RCP 2.6 given for time period: 2071-2100

Fire weather refers to weather conditions that are conducive to fire. These conditions determine the fire season, which is the period(s) of the year during which fires are likely to start, spread and do sufficient damage to warrant organized fire suppression. The length of fire season is the difference between the start- and end-of-fire-season dates. These are defined by the Canadian Forest Fire Weather Index (FWI; http://cwfis.cfs.nrcan.gc.ca/) start-up and end dates. Start-up occurs when the station has been snow-free for 3 consecutive days, with noon temperatures of at least 12°C. For stations that do not report significant snow cover during the winter (i.e., less than 10 cm or snow-free for 75% of the days in January and February), start-up occurs when the mean daily temperature has been 6°C or higher for 3 consecutive days. The fire season ends with the onset of winter, generally following 7 consecutive days of snow cover. If there are no snow data, shutdown occurs following 7 consecutive days with noon temperatures lower than or equal to 5°C. Historical climate conditions were derived from the 1981–2010 Canadian Climate Normals. Future projections were computed using two different Representative Concentration Pathways (RCP). RCPs are different greenhouse gas concentration trajectories adopted by the Intergovernmental Panel on Climate Change (IPCC) for its fifth Assessment Report. RCP 2.6 (referred to as rapid emissions reductions) assumes that greenhouse gas concentrations peak between 2010-2020, with emissions declining thereafter. In the RCP 8.5 scenario (referred to as continued emissions increases) greenhouse gas concentrations continue to rise throughout the 21st century. Multiple layers are provided. First, the fire season length is shown across Canada for a reference period (1981-2010). Projected fire season length layers are available for the short- (2011-2040), medium- (2041-2070), and long-term (2071-2100) under the RCP 8.5 (continued emissions increases) and, for the long-term (2071-2100), under RCP 2.6 (rapid emissions reductions).
