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

Land degradation/desertification

Local environmental knowledge

Pastoral livelihoods

International development

Regional focus: West Africa
