Efficacy of two lion conservation programs in Maasailand, Kenya

Hazzah and colleagues evaluated whether a Maasai-warrior employment scheme (Lion Guardians) and a livestock compensation program reduced lion killing in southern Kenya. Using long-term lion-mortality data across treatment and control areas, they found that the Lion Guardians program, which hired warriors to monitor lions, recover lost livestock, and reinforce bomas, was associated with significantly fewer lions killed than compensation alone. The study argued that culturally grounded, employment-based interventions addressing the social drivers of retaliation outperformed payments, which can struggle with verification and dependency. It is a leading example of rigorously measuring the conservation outcomes of competing conflict-mitigation strategies.
