About Stefanie Herrmann
I am a geographer pursuing interdisciplinary research on human-environment relationships in drylands, in particular in pastoral and agricultural societies of the developing world. Most of my research has been in the semiarid Sahel of West Africa, where I have worked on land degradation and land cover dynamics at various scales and from various perspectives, ranging from regional-scale remote sensing to studying the perspectives of local populations in the field.
Areas of Study
Remote sensing of land use and land cover change
Local environmental knowledge
Regional focus: West Africa
