Innovating for People and the Planet: The Scientific History of TNC

Science is the backbone of The Nature Conservancy’s mission to conserve the lands and waters on which all life depends. Science provides the evidence base for setting priorities, designing effective strategies and measuring impact. Science empowers TNC to address complex environmental challenges with solutions that are grounded in data, scalable across geographies and aligned with the needs of local people and communities.

From its origins in the Ecological Society of America to its evolution into a global conservation leader, science has always been core to the organization. Today, with nearly 1,000 science staff working across all 50 U.S. states and more than 80 countries and territories, TNC applies interdisciplinary science to address the twin crises of biodiversity loss and climate change. Our science staff—many of whom also serve as conservation practitioners, communicators and executive leaders—bring expertise from more than 60 disciplines/fields to develop scalable, locally grounded solutions.

TNC’s approach to science is collaborative, integrating cutting-edge technologies like remote sensing, artificial intelligence and bioacoustics with Indigenous and local knowledge. Whether advancing climate adaptation, marine spatial planning, sustainable agriculture, or natural climate solutions like agroforestry and reforestation, TNC science is designed to be used—informing decisions, guiding policy and driving impact at scale. For those seeking to create lasting change for people and nature, TNC offers a model where science is not just a tool, but a bridge to a better future.

Where Science Meets Impact

At TNC, science isn’t just a tool, it’s a bridge to a better future for biodiversity, climate and communities.

A Global Guide to Coral Reef Restoration

Over half of the world’s coral reefs have been lost in the past 50 years due to bleaching, disease and other threats. To support global restoration, TNC and partners created a science-based guide with best practices for species selection, nursery design, site choice and monitoring. It includes tools and case studies to tailor efforts locally and promotes scalable strategies that boost reef resilience, biodiversity and coastal protection.

Doubling Down on Nature for Water Security

Global investments in nature-based solutions for freshwater protection doubled over the past decade, reaching $49B across 880+ programs in 2023. Despite global disruptions, funding remains strong, led by China, the U.S. and the EU. A new report by TNC and Forest Trends highlights NbS like forest restoration and wetland protection as key to improving water quality, reducing flood risk and boosting climate resilience, calling for scaled efforts to meet rising water and climate needs.
