Regime Shifts in the Horn of Africa
Environmental regime shifts are abrupt shifts between contrasting ecosystem states when environmental conditions cross specific thresholds. Increasingly areas in the Horn of Africa undergo "Forest to Grassland Savanna" and "Bush Encroachment" regime shifts. The societal impacts are huge. Regime shifts can disrupt fundamental environmental services such as vegetation, water and biodiversity, erode human livelihoods, and contribute to human displacement and political fragility.
