This report examines how researchers design and implement methodological approaches in contexts marked by instability, insecurity, and institutional fragility. Drawing on 5,327 studies identified through a comprehensive mapping process, it analyses patterns in data collection, research design, analytical techniques, sectoral focus, and geographic distribution, revealing both dominant practices and critical gaps in the evidence base. Findings from this work will inform future research commissioning, highlight opportunities for methodological innovation, and support more context-appropriate, rigorous, and policy-relevant evidence generation in FCAS environments.
