Despite the advancement of more integrated land information systems (LIS), conflicts and disputes over land in Indonesia remain. Our study seeks to explain this situation. Using an interpretive case study conducted in Eastern Indonesia and framed within the concepts of information system (IS) artefacts, we find that tensions within and between information, technology, and social artefacts help to explain the sub-optimal LIS impacts. Inconsistent information, unsuitable technology, and conflicting social arrangements are examples of such tensions. Unless the tensions are properly resolved, LIS use cannot fulfil its potential for more appropriate management of land administration.
