Kerri Rademeyer

CEO, Alinea & WCP Zambia

Kerri leads efforts to strengthen conservation systems and support frontline partners across Africa. With a background in protected-area management and wildlife law enforcement, she co-founded WCP Zambia to combat wildlife crime through strategic partnerships with government, the judiciary, and local communities.

A passionate advocate for locally led conservation, Kerri brings a collaborative, systems-based approach to everything she does and is currently studying criminology and sociology to deepen her impact.
