3. Oceanography: bottom topography of the Atlantic, Indian and Pacific Oceans; temperature and salinity of the oceans; heat and salt budgets; ocean deposits; waves, currents and tides; marine resources — biotic, mineral and energy resources; coral reefs, coral bleaching; sea-level changes; law of the sea and marine pollution.
4. Biogeography: genesis of soils; classification and distribution of soils; soil profile; soil erosion, degradation and conservation; factors influencing world distribution of plants and animals; problems of deforestation and conservation measures; social forestry; agroforestry; wildlife; major gene pool centres.
5. Environmental Geography: principle of ecology; human ecological adaptations; influence of man on ecology and environment; global and regional ecological changes and imbalances; ecosystem, their management and conservation; environmental degradation, management and conservation; biodiversity and sustainable development; environmental policy; environmental hazards and remedial measures; environmental education and legislation.

HUMAN GEOGRAPHY

1. Perspectives in Human Geography: areal differentiation; regional synthesis; dichotomy and dualism; environmentalism; quantitative revolution and locational analysis; radical, behavioural, human and welfare approaches; languages, religions and secularisation; cultural regions of the world; human development index.
2. Economic Geography: world economic development — measurement and problems; world resources and their distribution; energy crisis; the limits to growth; world agriculture — typology of agricultural regions; agricultural inputs and productivity; food and nutrition problems; food security; famine — causes, effects and remedies; world industries — locational patterns and problems; patterns of world trade.
3. Population and Settlement Geography: growth and distribution of world population; demographic attributes; causes and consequences of migration; concepts of over-, under- and optimum population; population theories; world population problems and policies; social well-being and quality of life; population as social capital. Types and patterns of rural settlements; environmental issues in rural settlements; hierarchy of urban settlements; urban morphology — concepts of primate city and rank-size rule; functional classification of towns; sphere of urban influence; rural-urban fringe; satellite towns; problems and remedies of urbanization; sustainable development of cities.
4. Regional Planning: concept of a region; types of regions and methods of regionalisation; growth centres and growth poles; regional imbalances; regional development strategies; environmental issues in regional planning; planning for sustainable development.
5. Models, Theories and Laws in Human Geography: Systems analysis in human geography; Malthusian, Marxian and demographic transition models; Central Place theories of Christaller and Losch; Perroux and Boudeville; Von Thunen's model of agricultural location; Weber's model of industrial location; Ostov's model of stages of growth; Heartland and Rimland theories; laws of international boundaries and frontiers.

BOOKLIST

STRATEGY

• Diagrams and maps are non-negotiable. A Geography answer without a diagram loses marks even if the content is perfect. Practise drawing India's outline in 60 seconds.
• Paper I is theory-heavy — master the models (Von Thunen, Weber, Christaller, Rostow, Heartland/Rimland) with diagrams.
• Paper II is India-specific and current-affairs linked — connect to recent projects, policies and disasters.
• Answer structure: concept → diagram → example → contemporary linkage.
• Solve 15 years of PYQs; Geography repeats themes and map-based questions heavily.

Pros: enormous GS overlap (GS-I + GS-III + Prelims), scientific/logical structure, diagrams substitute for words. Cons: Paper I theory is dense; requires sustained map practice; syllabus is longer than Sociology or Philosophy.
