Climate change and global warming impact the availability of water in the future, and this in turn is closely connected to the economics of water use in Canada. Hence, ground and surface water changes in central and western Canada between 2002 and 2017 were performed to understand if and how biophysical and land use land cover dynamics influence these changes. The selected provinces include British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and Quebec. To achieve the above goal, this research study is designed to answer the following research questions: (1) How do we know if and how ground and surface water changes took place in Canada’s intensive agriculture regions with rich natural resources that are important for food security and economy (2002-2017)? (2) How do we determine which areas are experiencing negative or positive changes (trends) of environmental issues (i.e., annual net primary productivity (ANPP), percent tree cover (PTC), evapotranspiration (ET), land surface temperature (LST), enhanced vegetation index (EVI), leaf area index (LAI) during the same timeframe (2002-2017)? (3) What are the patterns and rates of change of land use and land cover (LULC), including deforestation, urbanization, and agriculture expansion over time (2002-2017)? (4) What are the patterns and rates of change of social (e.g., population count, population density) and economic (e.g., energy use, per capital income, housing values, median household income) parameters in those regions? This research talk will cover results and findings from the proposed research as well as some policy relevant options with regard to sustainable water use.
