​​At Conservation International we believe that investing in talent is fundamental to our mission and key to providing sustainable solutions. In that spirit, the Lui-Walton Innovators Fellowship program hosts conservation fellows — academics, scientists, public and private sector leaders, independent scholars and policy analysts — who work to create dynamic and unconventional approaches to address existing barriers to sustainability and contribute to a shift in how nature is valued. These fellowships provide unparalleled opportunities for intensive focus and achievement at the intersection of climate, conservation, business and technology.

The program engages recognized leaders — Distinguished and Senior Fellows — and emerging talent — Technical Fellows — to provide fresh thinking and extensive leadership to Conservation International’s work around the world. By strategically combining the skills and knowledge of both groups, the Lui-Walton Fellows are able to expand the breadth of their skills, gain valuable experience in their fields, and find innovative solutions together with Conservation International program staff and local partners.

The Lui-Walton fellowship is distinguished by four ​​key areas of opportunity: travel, access to resources, professional development and direct participation in Conservation International programs.

Hindou Oumarou Ibrahim

As Conservation International’s Lui-Walton Senior Indigenous Fellow, Hindou Oumarou Ibrahim advocates for greater inclusion of indigenous groups — and their knowledge — in the global climate movement.

A member of the Mbororo semi-nomadic community, she leads the Association for Indigenous Women and Peoples of Chad. Lake Chad, a water source for 40 million people, has lost 90 percent of its surface area in just 40 years. As conflict has increased among groups competing for this essential resource, Ibrahim began the first major dialogue among the area’s numerous cultures and communities. Together, they are creating a 3D-map of the environmentally fragile region to inform conservation and resource management while promoting security.

Over the last decade, Hindou has worked with indigenous communities at the local and international levels to give a voice to those who are never heard — and to make governments and the private sector listen. She is a United Nations Sustainable Development Goals Ambassador and a member of the UN Permanent Forum for Indigenous Issues, and she served on the Key Advisory Committee to the Secretary General for the 2019 Climate Action Summit. In 2019, Hindou won the Pritzker Emerging Environmental Genius Award; was listed as one of 15 women leading the fight against climate change in Time Magazine; was featured in ELLE Magazine’s first-ever conservation issue; and delivered a powerful TEDWomen talk.

“With the world population projected to reach 9 billion in the next forty years, doubling our demand for food, water and energy, we must nurture ingenuity, initiative and talent to ensure these vital natural resources and the services they provide are protected. Melani and I are delighted to join Yvonne in welcoming the first class of Lui-Walton Innovator Fellows to Conservation International. This group’s skills and ideas will have a lasting impact on our ability to solve the conservation challenges of today and tomorrow.”
