Rajarshi's research interests lie in risk-sensitive land use planning and evidence-led decision-making using geospatial tools and applications. His research broadly focuses on the planning and evaluation of land-based mitigation and adaptation strategies, covering land use, forest management, and biodiversity conservation policies. He explores conservation co-benefits and their role in climate change adaptation and disaster risk reduction. With over 10 years of experience spanning industry and academia, Rajarshi has led and contributed to multiple field-based action research projects across South and Southeast Asia, particularly in India, Bangladesh, Myanmar, and the Philippines. Before joining IIT Delhi, he was a Senior Policy Researcher (Climate Change Adaptation) at the Institute for Global Environmental Strategies (IGES), Japan. Prior to that, he was a JSPS Postdoctoral Fellow at the Laboratory of Landscape Ecology and Planning, University of Tokyo. Rajarshi actively contributed to global science and policy platforms, including the IPCC and IPBES. He serves as a subject editor for leading international journals such as Sustainability Science (Springer) and Anthropocene Science (Springer). He is also a visiting faculty member at the University of Tokyo and the United Nations University, Tokyo.
Through his work, Rajarshi aims to bridge science, policy, and practice, ensuring sustainable and equitable solutions for climate resilience and biodiversity conservation.
