We want a world that is thriving, sustainable, and inclusive.

An Environmental Organisation with a Difference

We have had an on-the-ground presence in East Africa for the last 15 years, which has enabled us to build strong connections with both our clients and conservation communities. This local engagement positions our experts prominently in the environmental space and equips us with the knowledge to convey complex messages to a variety of groups, from implementing conservation arrangements with local communities to high-level dialogue with policy leaders.

"With a small, agile team of 20 people based in East Africa, we can mobilise our experts quickly and drive projects forward within tight timeframes."

Our team

Our team is a rare combination of experts who have spent years as both academic researchers and practitioners in fields ranging from conservation, ecology, and development to impact-focused finance and agriculture. This breadth of skills and knowledge has enabled us to work with a range of clients and a diverse project base to date. Nearly all our team members are from the regions we work in, combining our in-depth sectoral knowledge with local nuance, practicalities, language, and cultural understanding.
