The association, founded in 1989, is devoted to bringing together multi-disciplinary researchers, practitioners, and policymakers for the purpose of improving governance and management, advancing understanding, and creating sustainable solutions for commons, common-pool resources, or any other form of shared resource.

The IASC aims to:

– foster mutual exchange of scholarship and practical experience
– promote appropriate institutional design


In honor of Esther Mwangi

It is with great sadness that we inform you of the passing of IASC Council member and friend, Esther Mwangi. She died on Saturday, October 5 in a hospital in Nairobi, Kenya due to complications from cancer. Esther did research on gender and land-rights inequities in relation to natural resources at the Center for International Forestry Research (CIFOR) and got her PhD at Indiana University in 2003 with Elinor Ostrom. In December 2018, Esther was elected to the IASC Council. Esther was highly respected among her colleagues and a dear friend to many of us in the IASC community. She was 53 years old.

You can share your stories at Esther’s memorial website and read more about her life and research here.
