Résumé(Sommaire disponible en anglais seulement)
Environmental instability may prove to be the greatest threat Canada will face over the next several decades. Across the country, Canadians are adapting to a 'new normal' that is difficult to prepare for. Does this new normal include more frequent catastrophic floods like Calgary in 2013 and the 100-year Ottawa floods in 2017 and 2019. Is there an increase to the frequency and impact of forest fires like 'The Beast' in Fort McMurray 2016? Are crop and orchard failures going to continue to increase? How many major resource development projects can the landmass support? These questions are challenging to answer and the cost of not answering them is massive.
This environmental instability is being fueled by a combination of abrupt change drivers including human activity, forest fires, and floods, as well as gradual change drivers like climate change, pollution, and species adaptation. Together, these change drivers can be complex and interactive; where gradual changes cause abrupt changes and vice versa. Effective management of any region in Canada must start with a demonstrated understanding of how these change drivers are impacting the status and trends of that region.
Ensuring that Canadians are able to thrive in Canada's changing environment requires an intimate understanding of how the landmass is changing. To support the development of this knowledge, the Canada Centre for Mapping and Earth Observation (CCMEO) of Natural Resources Canada (NRCan) has implemented the Status and Trends Mapping Program (STMP). The STMP will identify, develop, disseminate and analyze critical geospatial datasets for describing a changing Canadian landscape to inform evidence-based decision-making.
The 5-year project 'Earth Observation Baseline Data for Cumulative Effects' (EO4CE) is the key launch effort for CCMEO's STMP. The project, currently in its second year, will develop a wide range of status and trends variables (primarily terrestrial) and demonstrate their capabilities within regional assessments of cumulative effects. In fiscal year 2019-20 (April 2019 - March 2020), the EO4CE project has exceeded expectations as articulated within the project plan.
Significant data products have already been developed and released, including land cover, a wetlands inventory, snow/ice extents, vegetation indices, and imagery mosaics. A schedule of data products to be developed and released over the course of the EO4CE project has been developed (figure 1.5).
Development of innovative scientific knowledge, methods, datasets, and tools, some highlights include: Local optimization methods (moving windows) for improving regional accuracy of classifiers in national mapping applications; Development of a 200 year daily climate record at national scale (historical & forecast); Discovery of freezing temperature controls in aquifer discharge in cold region watersheds; Discovery of the impact of water storage on ground surface subsidence in Southern Ontario.
Leadership and expertise has been demonstrated within NRCan and with other government departments and agencies through workshop development and participation, and provision of advice on regional selection.
Collaborative activities have been established with numerous organizations including within the federal government (Environment and Climate Change Canada, Agriculture and Agri-Food Canada, Public Safety Canada), with provincial/territorial governments (NL, QC, NWT), academia (U-Ottawa, McMaster-U, U-Sherbrooke, Memorial U, U-Lethbridge, U-Waterloo), and non governmental organizations (Ducks Unlimited Canada).
10 scientific publications have been produced and a further 6 have been developed and/or submitted for journal review. Although not all journals maintain real-time readership figures, those that do have already demonstrated in excess of 1,500 readers over the short time these publications have been available.
Collectively, these efforts are enhancing Canada's capacity to conduct regional assessments of cumulative effects. These data and science outputs will enable not only assessment processes, but also the ongoing monitoring programs required to support the integrity of Canada's communities and ecosystems alongside industrial development.
Résumé(Résumé en langage clair et simple, non publié)
Cette publication documente les travaux réalisés à ce jour sur le projet « Données de référence sur l'observation de la Terre pour les effets cumulatifs », qui fait partie des efforts plus larges du gouvernement pour soutenir la nouvelle loi sur l'évaluation d'impact. Le document décrit les réalisations importantes de l'exercice 2019/20 pour le projet, y compris les diffusions de données, les publications scientifiques et les collaborations avec d'autres partenaires. Il souligne l'importance du projet et la manière dont il soutient les priorités des gouvernements en matière d'évaluation d'impact. Le document décrit comment le projet, actuellement dans sa deuxième année, développera un large éventail de variables d'état et de tendances (principalement terrestres) et démontrera leurs capacités dans les évaluations régionales des effets cumulatifs.
