Tripura Scientist takes centre stage in global push for Rice self-sufficiency in Africa

Text Size:

From the small town of Kailashahar in Tripura to one of the world's most influential platforms on agricultural policy, a scientist from the state is helping shape international conversations on food security, irrigation and sustainable farming.

At the recently concluded Global Rice Policy Dialogue in Addis Ababa, Ethiopia, Dr. Deb, a leading researcher in water and climate science, advocated a strategic roadmap to help African nations reduce dependence on imported rice and move towards greater self-sufficiency in food production. Rather than focusing solely on increasing cultivation areas, he stressed that the key to transforming rice production lies in identifying high-potential regions and investing in modern irrigation infrastructure capable of delivering long-term agricultural gains.

Addressing policymakers, researchers and development experts from across the globe, Dr. Deb highlighted how scientifically managed irrigation systems and efficient water-use practices could unlock vast agricultural potential across Africa. He argued that improving access to irrigation would not only increase rice production but also strengthen food security, enhance farmer incomes and build resilience against climate-related challenges.

His proposals are already moving beyond the discussion stage. As part of ongoing international collaboration, Dr. Deb is working closely with the Government of Kenya to develop a framework for identifying regions where irrigation investments can generate the greatest impact. The initiative seeks to balance agricultural expansion with sustainable management of water resources, ensuring that development remains both productive and environmentally responsible.

The two-day international dialogue, organised with the support of the African Union, the International Rice Research Institute (IRRI), AfricaRice and the Ethiopian Institute of Agricultural Research, served as a major platform for deliberations on policy reforms, agricultural innovation and food-security challenges confronting the African continent.

Currently heading the Water and Climate Research Unit at IRRI's South Asia Regional Centre in Varanasi, Dr. Deb has built a distinguished career around improving agricultural productivity through better water management. His work spans the fields of irrigation engineering, climate adaptation and sustainable farming systems, linking scientific research with practical solutions for millions of farmers.

His expertise is being applied across multiple large-scale projects. In Kerala, he is associated with a World Bank-supported initiative aimed at digitally monitoring water flow across an extensive canal-irrigation network covering more than 20,000 hectares. The project is expected to improve the efficiency of water distribution and strengthen decision-making in agricultural management.

Beyond the ground, Dr. Deb's research also extends into space-based technology. He is part of collaborative efforts with NASA scientists to validate information generated by NISAR, the joint Earth observation mission of NASA and ISRO. The project seeks to integrate satellite observations with agricultural and water-resource research, potentially revolutionising future planning in irrigation, climate monitoring and crop management.

Dr. Deb's journey from rural Kailashahar to the global scientific arena reflects a remarkable academic trajectory. After completing his doctoral studies at the University of Newcastle in Australia, he pursued advanced postdoctoral research at the University of Alabama in the United States before emerging as a recognised voice in international water and agricultural research.

As nations across the world grapple with food-security concerns, climate uncertainty and growing pressure on natural resources, the contributions of scientists such as Dr. Deb are gaining increasing significance. His work not only places Tripura on the global scientific map but also demonstrates how innovative research from India is contributing to solutions for some of the most pressing agricultural challenges facing the world today.
