The survey for practical consideration is crucial in social and policy science inquiries. Several systematic reviews in the post-conflict peacebuilding literature have thus far ignored its efficaciousness. This knowledge gap motivated in developing ConflictAffected Population Survey technique to survey the conflict-ravaged Chittagong Hill Tracts indigenous peoples for the purpose of examining peace hybridity in Bangladesh, as the quantitative part of the study. This article outlines guidelines for designing probabilistic sampling and survey procedures for a robust sequential explanatory mixed-methods case study research in a terrain where an accurate sample frame is difficult to define. The systematic methodological strategy adopted herein enabled the compilation of a comprehensive cross-sectional case study where findings are generalizable, especially the concept and model central to our thesis on indigeneity dilution.

The decade-long low-intensity armed conflict in the Chittagong Hill Tracts (CHT) that surfaced soon after the independence of Bangladesh (1971) due to the failure of the state-building project ended with the CHT Accord which was signed in 1997 between the government of Bangladesh and the Parbattya Chattagram Jana Sanhati Samiti (PCJSS). This study uses qualitative research methods to explore the fundamental research question of who is in the driver’s seat of the post-accord CHT peacebuilding process. A mostly top-down approach to peacebuilding has been used in the CHT due to an entirely donor-driven peacebuilding partnership between local and international stakeholders. Under this asymmetric power structure, the marginalization of local ownership is expected to produce unintended results in the peace process.
