The Henry Arnhold Fellowship is a one-year program by the Mulago Foundation designed to support leaders with scalable conservation and climate solutions. Each year, 8–10 fellows are selected to receive an unrestricted $100,000 grant and participate in two intensive week-long workshops focused on design for impact and strategy for scale. The fellowship aims to help fellows design high-impact solutions, build organizations to deliver them at scale, and become part of a growing community of innovators in conservation and climate.
