Land use change in the Ecuadorian páramo: The impact of expanding agriculture on soil carbon storage
The Andean páramo is notable for high soil carbon storage and its contribution to ecosystem services. However, the páramo’s ability to maintain high soil carbon levels is threatened by land use change from tussock grassland and shrublands to agricultural uses. A chronosequence study was conducted in...

In parallel, a land use and land cover classification of Landsat images was used to measure the change in agricultural areas between 1991 and 2017.
