Imalirijiit: A Community-Based Environmental Montoring Program in the George River Watershed, Nunavik, Canada

Water physico-chemistry variables (temperature, pH, specific conductivity, dissolved oxygen, turbidity, hardness, are measured in situ with an electronic probe (YSI ProDSS) and manual kits. Water samples are collected (unfiltered and filtered) for laboratory analyses of nutrients, dissolved organic carbon, major ions, trace metals, and rare earth elements (REEs). Samples were collected using the ‘clean hands, dirty hands’ sampling protocol for trace metals. A monitoring survey examining contaminants in country food was initiated in 2017 in collaboration with the Hunter’s Support Program. Inuktitut and English sampling kits were prepared for whitefish, seal, caribou, and lichen. The samples were frozen and later sent to University of Montreal for laboratory analysis of contaminants. Environmental change study at the watershed scale rely on remote sensing database since 1985: Landsat-5, 7, 8, and Sentinel-2. NDVI and NARI indexes are to assess environmental change including vegetation phenology, landslides, and channel erosion and sedimentation. We develop new tools to measure shrubs cover. For the interactive map (uMap) we document Inuit land use, animal and plant species’ ecology, the river’s biophysical processes, and observed changes in the watershed. We conducted semistructured mapping interviews with local experts using a questionnaire about life stories, land uses, animal and plant species, local toponymy, changes in the river watershed, and stories linked to the river.
