Ashley School of Global Development and the Environment

We unite science, innovation, and real‑world engagement to develop leaders who create practical solutions for improving lives, strengthening ecosystems, and driving positive global impact.

A Nexus for Environmental Problem-Solving

The Ashley School at Cornell CALS is a dynamic hub for addressing complex challenges facing people and the planet in the 21st century. Emphasizing education with impact, we contribute our broad interdisciplinary expertise to pioneer practical solutions, emphasizing real-world engagement with communities in New York state and more than 30 countries around the globe to improve lives and livelihoods and promote environmental stewardship. 

This is our global perspective on how we support society.

As the only Ivy League university with a Land-Grant mission, we uniquely integrate world-class research and education with community engagement in service of the public good. Our faculty, students and partners coalesce around urgent themes – from climate resilience and biodiversity loss to sustainable agriculture and food system transformation – working with stakeholders to create solutions that are locally grounded and globally relevant.

Leveraging our two distinguished sections – Global Development and Natural Resources and the Environment – the school takes a transdisciplinary approach to integrate ecological science, social innovation and community engagement to foster sustainable, resilient and prosperous futures.
