Welcome to IBRU

Since its founding as the International Boundaries Research Unit in 1989, IBRU has been the world’s leading research centre on international boundary making and dispute resolution. Today, IBRU joins work in international boundary law with the geographic study of borders and bordering in the 21st century. 

Through research, consultancy, and training, IBRU facilitates enhanced understanding of border areas, contributes to the peaceful resolution of boundary disputes, and engages with broader geographic questions concerning the changing nature of sovereignty, territory, citizenship, and the political organisation of space. 

IBRU is part of the Geography Department at Durham University.
