AbstractEstimates of land use change (LUC) and resulting Greenhouse Gas (GHG) fluxes in Canada's North are needed for reporting to the United Nations Framework Convention on Climate Change. This paper presents a remote sensing based approach and results for estimating non-forest LUC over Canada's arctic/sub-arctic zone. Spatial datasets portraying the occurrence of cultural features were used to identify high probability LUC areas within a 359 million ha northern study region. These targeted areas were analyzed using multi-temporal Landsat satellite imagery from circa 1985, 1990, and 2000. A Land Use Change Mapping System for Canada's North (LUCMAP-N) was developed by combining several image normalization and change detection techniques recently devised at Natural Resources Canada's Earth Sciences Sector (NRCanESS). It is estimated that the average rate of LUC during 1985-2000 over Canada's arctic/sub-arctic region was 666 ha/yr.
