The importance of regional studies in understanding national issues for UPSC lies in their potential to highlight local perspectives and their impact on governance. Knowledge of regional diversity—cultural, economic, and environmental—enriches candidates' understanding of how policies affect different areas. This awareness allows aspirants to address issues like resource allocation and development disparities competently. Moreover, regional studies enhance interview performance by enabling candidates to discuss relevant local issues confidently. Understanding regional dynamics contributes to a comprehensive grasp of national challenges, fostering informed decision-making in the civil services.
