Start by planning research that stays tightly focused on the research question: To what extent has sea-level rise contributed to internal climate migration from the coastal districts of Khulna Division, Bangladesh between 2000 and 2020, and how have economic and political institutions shaped migrants’ adaptive strategies? Map the concepts you must cover (sea-level rise, internal migration, economic institutions, political institutions, adaptive strategies) and decide which disciplines will inform each (physical geography, development economics, political science, migration studies). Assemble a bibliography that mixes peer-reviewed articles, UN/World Bank/ADB reports, Bangladesh government statistics (Bangladesh Bureau of Statistics, Local Government Engineering Department), NGO case studies, and primary sources such as tide-gauge and satellite data (e.g., AVISO, ESA) for 2000–2020. Create a timeline and data inventory showing which quantitative datasets and qualitative sources cover which years and districts so you can match changes in sea level and environmental conditions to observed migration patterns within the 2000–2020 window. Plan ethics approval and informed consent for any interviews and ensure translation/field access arrangements if you will conduct fieldwork in Khulna or with migrants now living elsewhere in Bangladesh or abroad internally housed in cities like Dhaka or Jessore settlements. Be explicit about the limits of available data and how you will address gaps (triangulation, proxies such as salinity intrusion, land loss mapping, or household recall surveys).
Design a mixed-methods approach that lets you show both magnitude and mechanism. For the quantitative strand, use time-series or panel data where possible to compare migration rates across coastal upazilas with measured sea-level indicators, land subsidence and salinity intrusion; use GIS to map hotspots and change over time (2000–2020). Apply basic statistical tests (differences-in-differences, correlation, regression with controls for floods, storms, land loss, poverty) while clearly noting causation limits. For the qualitative strand, conduct semi-structured interviews and focus groups with migrants and key informants (local government, NGOs, microfinance officers) to identify how institutions influenced choices and adaptive strategies (remittances, livelihood shifts, legal access to land, social protection). Use process tracing to link institutional actions to on-the-ground responses and code transcripts thematically to show patterns. Triangulate findings: quantitative trends should be illustrated with concrete migrant narratives and institutional documents to explain mechanisms.
When writing, follow a clear structure: introduction with the research question, conceptual framework (vulnerability, adaptive capacity), methods, results (quantitative then qualitative), discussion comparing the extent of sea-level-driven migration and the institutional shaping of adaptation, and a balanced conclusion with explicit limitations and implications for policy. Present maps, charts, and selected quotes to support claims and always link evidence back to the research question. Be transparent about uncertainty and alternative explanations (storms, livelihoods, social networks) and explicitly evaluate how economic and political institutions enabled, constrained, or redirected adaptive strategies. Follow IB formal requirements (word count, citations) and use consistent referencing so examiners can verify sources.
