Understanding geographical concepts is crucial for UPSC candidates as they form the backbone of social and economic systems. Geography influences population distribution, resource management, and environmental challenges, all of which are integral to policymaking and governance. Candidates must grasp both physical and human geography to effectively analyze issues like urbanization, regional disparities, and climate change impacts. Additionally, questions in the exam often connect geographical knowledge to current affairs, making it essential for aspirants to integrate these concepts into their broader study framework.
