Estimation of land-use/land-cover changes associated with energy footprints and other disturbance agents in the Upper Peace Region of Alberta Canada from 1985 to 2015 using Landsat data

•New approach to large-area land change attribution using time-series Landsat data.•Natural and anthropogenic disturbance agents identified over complex landscape.•Cutblocks most dynamic, showing both tree loss and subsequent regeneration.•Forest regeneration from energy footprints takes longer than cutblocks and wildfire.•Assists efficient land-use decision-making to achieve environmental sustainability.
