Overview The Ministry of Science & Technology has piloted a navigation‑technology project on Car Nicobar Island, introducing GPS devices to tribal fishermen. Tailored by the Central Island Technological Research Institute (CITRI) under the DST SEED Division programme , the intervention aims to overcome the traditional challenges of unpredictable seas and lack of precise navigation tools. Key Developments Provision of ten GPS units – five allocated to individual fishermen and five for communal use. Training of fishermen on modern navigation and fishing techniques, conducted in collaboration with the local Tribal Council . Establishment of a Coastal fisheries information hub on Car Nicobar to share real‑time fishing‑ground data. Surveys to assess fishermen’s needs, ensuring technology adoption aligns with community practices. Important Facts Since the rollout, daily catch volumes have risen by an average of 168% , despite a reduction in time spent at sea due to precise navigation. Fishermen such as Mr. Junaid (Teetop village) and Mr. Abdul Sattar (Chuchucha village) have shifted from subsistence to market sales, boosting household incomes. The increased supply of fresh fish has improved protein intake and overall nutrition for the Nicobarese communities , contributing to better health outcomes. UPSC Relevance This case illustrates the intersection of science & technology policy (GS3) with rural development and tribal welfare (GS2). It showcases how targeted technological interventions can address geographic isolation, enhance livelihood security, and improve nutritional status – themes pertinent to questions on sustainable development, coastal resource management, and the role of central ministries in implementing grassroots programmes. Way Forward Scale the GPS model to other remote islands and coastal tribal regions. Integrate real‑time data analytics for predictive fishing‑ground mapping. Strengthen capacity‑building modules to include post‑harvest handling and market linkage. Monitor health and income indicators to assess long‑term impact on community well‑being.
