Directive word: Explain
This question asks you to explain. The directive word signals the depth of analysis expected, the structure of your answer, and the weight of evidence you must bring.
See our UPSC directive words guide for a full breakdown of how to respond to each command word.
How this answer will be evaluated
Approach
The directive 'explain' demands conceptual clarity with causal reasoning across all three parts. Allocate approximately 40% of word budget (~400-450 words) to part (a) given its 20 marks, with 30% each (~300-350 words) to parts (b) and (c). Structure: brief integrated introduction → part-wise treatment with diagrams for (a), case-based discussion for (b), and stage-wise exemplification for (c) → synthesizing conclusion on spatial-economic interdependence.
Key points expected
- Part (a): Losch's hexagonal market areas with multiple K-values (3, 4, 7), derivation of 150° principle for industrial location, and critique citing rigid geometry, homogeneous plain assumption, and neglect of transport cost variations
- Part (a): Hand-drawn diagram showing nested hexagons with overlapping market areas, industrial sectors arranged by K-values, and 150° rotation for least transport cost
- Part (b): SLM's triple bottom line approach—environmental (soil-water conservation), economic (productivity enhancement), social (livelihood security)—with mechanisms like integrated watershed management and agroforestry
- Part (b): Indian examples such as Sukhomajri model (Haryana), watershed development in Rajasthan's Alwar district, or tribal land tenure reforms under FRA 2006
- Part (c): Stage-wise correlation: Stage 1 (high BR/DR) with pre-industrial Sub-Saharan Africa; Stage 2 (declining DR) with India's demographic dividend; Stage 3 (low BR/DR) with Japan's aging; Stage 4/5 with Germany's negative growth
- Part (c): Critique of Eurocentric model using Kerala vs. UP divergence within India, and Islamic world's unique fertility transitions challenging classic DTT
Evaluation rubric
| Dimension | Weight | Max marks | Excellent | Average | Poor |
|---|---|---|---|---|---|
| Concept correctness | 22% | 11 | Precise exposition of Losch's K-system and 150° principle; accurate delineation of SLM's three pillars and their synergies; correct stage definitions with BR/DR thresholds for DTT; distinguishes Losch from Christaller's administrative/marketing principles | Basic understanding of hexagonal patterns and SLM components; general awareness of DTT stages but confused thresholds or causation; conflates Losch with Christaller's central place hierarchy | Fundamental errors—describes von Thünen rings instead of Losch hexagons; treats SLM as mere soil conservation; describes population pyramids without stage linkage; misidentifies demographic stages |
| Map / diagram | 18% | 9 | Original hand-drawn diagram for (a) showing: nested hexagons with K=3,4,7 values, 150° rotation for industrial sectors, overlapping market areas; properly labelled axes and legend; may include sketch map for (b) showing watershed boundaries or (c) showing demographic transition curves | Standard hexagon diagram without K-value specificity or rotation angle; borrowed from standard texts without adaptation; diagrams present but poorly labelled or missing scale | No diagram for (a) despite explicit demand; irrelevant diagrams (e.g., population pyramid for DTT without transition curves); copied diagrams without understanding |
| Indian regional examples | 20% | 10 | For (a): Indian industrial location patterns (e.g., cotton textile in Mumbai-Pune corridor) analyzed through Loschian lens; for (b): specific SLM cases—Sukhomajri, Pani Panchayat, or MGNREGA watershed works; for (c): intra-Indian contrasts (Kerala Stage 3 vs. Bihar Stage 2) and global South examples (Bangladesh's stalled transition) | Generic mention of 'watershed projects in India' or 'population control in India' without specificity; examples correct but not integrated with theory; only one part has Indian examples | No Indian examples despite applicability; inappropriate examples (e.g., European green deal for SLM); factually wrong case citations |
| Spatial analysis | 20% | 10 | For (a): analysis of how K-values create spatial hierarchy of industrial concentration; for (b): spatial differentiation of SLM strategies across agro-ecological zones (arid vs. humid tropics); for (c): spatial patterns of demographic transition—core-periphery divides, urban-rural differentials, and migration impacts on regional demographics | Acknowledges spatial aspects without systematic analysis; describes locations without explaining spatial processes; treats cases as isolated rather than spatially interconnected | A-spatial treatment—discusses SLM as universal prescription, DTT as global average; no recognition of spatial heterogeneity; confuses temporal and spatial dimensions |
| Application / policy | 20% | 10 | Critically evaluates Losch's relevance for contemporary industrial policy (SEZs, logistics hubs); proposes SLM integration with SDG-15 and India's Land Degradation Neutrality targets; assesses DTT's policy implications—whether demographic dividend can be captured through education/health investments, critiques coercive population policies | Lists policy measures without critical evaluation; accepts models uncritically for policy application; mentions relevant policies (National Watershed Project, National Population Policy) without linking to theoretical framework | No policy dimension; purely theoretical treatment; inappropriate policy recommendations (e.g., forced sterilization citing DTT); confuses Losch with current industrial location theories |
