Sustainable Development Goal 16 commits to 'promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels'. While the concerns of SDG16 with violence reduction, rule of law, and governance are relevant to all societies, this paper focuses on fragile and conflict-affected countries, many of which have the hardest task in achieving SDG16. It analyses how higher education can contribute towards--or detract from--SDG16 through teaching, research, governance, and external leadership. It then analyses four dynamics influencing the agency of universities in fragile and conflict-affected contexts in engaging with SDG16: resource mobilisation and the public good; securitisation; academic freedom, insecurity, and politicisation; and tensions between demands for localisation and the universalising logics of liberal peacebuilding models and the SDGs.
