SciComm ThinkLabs (2023–24) is a practitioner-led initiative convened by FAST India to strengthen the science communication ecosystem in India through collaborative enquiry, collective sensemaking, and co-created tools. Over six months, sixteen science communication practitioners worked across four themes, landscape of SciComm in India, institutional SciComm, capacity-building, and science–media interfaces, to analyse sectoral gaps and develop practical resources. The final report synthesises their findings, evidence, and recommendations, and presents three key outputs: a SciComm Readiness Tool for institutions, a modular training framework, and a Science Journalist Residency framework. The report provides a grounded, practitioner-driven perspective on the current state of science communication in India and outlines pathways for strengthening practice, capacity, and institutional support across the ecosystem.
