Ghana Annual Conversion to Gold Mining 2007-2017 and Total Conversion up to 2019

These data are associated with an article published in Science of the Total Environment in 2021 (currently in revision). In this study, the Landsat image archive available through Google Earth Engine was used to quantify the total footprint of vegetation loss due to artisanal gold mines in Ghana from 2002-2019 and understand how conversion of forested regions to mining has changed over a decadal period from 2007-2017. Areas that experienced anomalous vegetation loss from 2005 to 2019 were identified through assembling a Landsat imagery timestack from 2002 to 2005. A separate imagery timestack was assembled from 2010 to 2019 to establish an observation period. A combination of machine learning and change detection algorithms were then used to calculate land cover conversion to gold mining and the timing of conversion annually. Details regarding methods and Earth Engine code can be found in the supplemental information with the manuscript.
