What: India announced it will conduct the Population Census 2027 in two phases, marking the resumption of the decadal census exercise that was delayed from 2021 due to the COVID-19 pandemic. Significantly, this census will include comprehensive caste enumeration alongside traditional demographic data collection—a decision addressing long-standing demands for updated caste data to inform social welfare policies and reservation frameworks. The last caste census (Socio-Economic and Caste Census – SECC) was conducted in 2011, and before that in 1931. This exercise will provide crucial data on population size, literacy, employment, housing, and social composition for policy planning.

How: The two-phase approach involves: Phase 1 – house listing and housing census covering all residential and institutional structures, infrastructure availability, and amenities; Phase 2 – population enumeration capturing demographic details, economic activity, migration, disability, religion, caste, and socio-economic indicators. The census employs a mobile application-based data collection system, replacing traditional paper schedules, enabling real-time data capture, validation, and processing. The Office of Registrar General and Census Commissioner coordinates with state governments, employing approximately 3 million enumerators and supervisors. Caste data will be collected at the household level with self-declaration, requiring careful handling given its sensitive nature and policy implications for OBC reservation and sub-categorization.

Why: Critical for UPSC GS2 (Governance – Census & Data) and GS2 (Social Justice – Reservation Policy) as census data forms the foundation for policy planning, resource allocation, and constitutional provisions. Questions on census periodicity, ORGI functions, caste census debate, data privacy, and demographic trends appear regularly in prelims and mains. This provides excellent content for answers on evidence-based policymaking, social justice data requirements, OBC sub-categorization, delimitation freeze linkage to census, federal data collection challenges, and balancing transparency with privacy—themes appearing in GS2 governance papers, social justice answers on reservation policy, and ethics discussions on data collection and minority protection.

What: Khichan and Menar wetlands from Rajasthan were designated as Ramsar sites, joining India’s growing list of internationally recognized wetlands of ecological importance. Khichan, located in Jodhpur district, is famous as the winter habitat for thousands of migratory Demoiselle Cranes that travel from Mongolia and Central Asia. Menar wetland in Udaipur district supports diverse aquatic biodiversity and serves local communities. This addition increases India’s Ramsar site count (currently over 80 sites covering more than 1.3 million hectares), reinforcing the country’s commitment to wetland conservation under the Ramsar Convention signed in 1971.

How: Ramsar designation requires demonstrating the wetland’s international importance based on criteria including: supporting vulnerable species, hosting significant waterfowl populations, maintaining biodiversity, or representing rare wetland types. The nomination process involves scientific documentation by state forest departments and Wetlands International – South Asia, assessment by the Ministry of Environment, Forest and Climate Change (MoEFCC), and submission to the Ramsar Secretariat in Switzerland. Designated sites receive management support through Wetlands Conservation Programme, integrated management plans, community participation frameworks, and monitoring protocols. Khichan’s conservation success stems from community-led protection where villagers feed visiting cranes, demonstrating participatory conservation. Menar supports fishing communities while maintaining ecological functions.

Why: Highly relevant for UPSC GS3 (Environment – Biodiversity Conservation) and GS1 (Geography – Rajasthan) as wetland conservation, migratory species protection, and international environmental conventions are important topics.
