The accountability of governance arrangements for climate adaptation is little theorized, let alone having benefitted from empirical work to investigate what it entails in practice and under what conditions it is achieved. This is particularly the case with respect to the increased proliferation of digital forms of governance. This study examines the implications for accountability within adaptation planning and policy of e-musrenbang, a digital governance tool utilised in Indonesia, focusing on districts of Surabaya exposed to coastal flooding and sea-level rise. It will provide greater understanding of how accountability can be enhanced across a range of similar contexts.
