Born and raised in Madagascar, Tiana joined Fanamby — a nonprofit working on sustainable management of harmonious protected areas — in 2009. Her goal with the team is to establish cooperatives-driven conservation within harmonious protected areas. As everyone benefits from watersheds, the aim is to ensure supply chains are not only traceable but also sustainable for all.
With a background in biochemistry, Tiana has spent the past 20 years designing and implementing strategies that combine conservation, social enterprise and land-use planning. Under her leadership, Fanamby co-manages more than one million hectares of protected areas across Madagascar and supports the creation of two social enterprises. The organization has built value chains in sectors such as vanilla and spices, fishery and pro-conservation agroecology that directly benefit local producers while reducing pressure on ecosystems.
In 2021, she joined the fellowship of the Women for the Environment in Africa movement, which supports transformative leadership for women conservation leaders across the continent. She was also recognized as one of the 100 Young African Leaders in Environment, and in 2025, she completed the Monitoring, Evaluation and Learning for Impact Program (MELP), supported by Maliasili — and the Henry Fellowship Program of the Mulago Foundation — strengthening her team’s ability to track outcomes and scale impact.
Her approach is rooted in practical solutions and long-term partnerships — with communities, government and the private sector. She believes in models that are replicable, measurable and adaptable to different contexts, particularly in the Global South.
