Tracking the Global Story of Khat: From Banned Stimulant to Hidden Economy
This PhD investigates how Ethiopia and Kenya’s khat economies adapted after the UK ban, combining Earth observation, AI, and economic modelling to assess resilience in livelihoods, land use, and ecosystems. Using satellite data and socio-economic analysis, it reveals how global drug policies reshape rural development, sustainability, and agricultural transitions.
