Healthy ecosystems and thriving communities depend on one another.

Rafael is the founder and Chairman of Meteologica, a technology and research company specialising in weather and climate information. Trained as a forest engineer, he has spent decades building organisations and teams while maintaining a strong commitment to conservation. At EHI, he brings together his experience in business and science with a deep curiosity about the natural world and a belief in thoughtful, ambitious work.

Bryan brings more than two decades of experience at the intersection of conservation, climate resilience and sustainable development. His career has taken him across Africa and beyond, spanning field-based conservation, forest management, environmental policy, carbon markets and large-scale landscape restoration.

He has held leadership and advisory roles with organisations including Eden: People+Planet and Compassionate Carbon. He is also a co-founder and Chairman of the Kijabe Forest Trust in Kenya, reflecting a long-standing commitment to locally rooted conservation.

George’s life and work have been closely tied to the Maasai Mara and to the wider landscapes of East Africa. Raised in the Mara, he grew up with an early understanding of its communities, wildlife and the ways in which people and the landscape shape one another.

Over the course of a varied career in safari, aviation, wildlife filmmaking and conservation, he has seen the region from many different angles and developed a deep understanding of the forces shaping its future. He founded the Dawntodusk Foundation to support community-led conservation in the Mara, and has long worked towards finding practical ways for people and wildlife to continue to share the landscape.

Calvin Cottar established Cottar’s 1920s Camp in Olderkesi with a vision of conservation that extends beyond protecting wildlife to supporting the people and landscapes that sustain it. Through the Cottar’s Wildlife Conservation Trust and his work in Olderkesi, he has helped develop a model that brings together wildlife protection, land rights, community livelihoods and responsible tourism.

His work has contributed to protecting an important wildlife corridor between the Maasai Mara, Serengeti and Loita ecosystems, while creating tangible incentives for local landowners to conserve the landscape. He brings to EHI a deep knowledge of East African conservation and a practical understanding of how environmental protection can be rooted in the interests of the people who live alongside it.
