(a) How do agro-climatic and land capability indicators assist in macro-agricultural regionalisation of India ? Illustrate with…

(a) Agro-climatic regionalisation India’s macro-agricultural regionalisation is a spatial ordering of climate, soils and production potential. The Planning Commission’s exercise used Thornthwaite and Trewartha climate classifications, rainfall variability, thermal regimes and length of growing period, together with ICAR land capability classes I–VIII based on soil depth, texture, drainage, slope and erosion status. These indicators were integrated into 15 zones and 73 sub-zones, later refined in ICAR’s 127 agro-climatic zones. They assist planning by matching crops, irrigation, soil conservation, credit and extension to biophysical potential: classes I–III suit intensive cereals, IV–VI need conservation, VII–VIII are mainly forestry or pastoral. Map: on an India outline, label Western Himalayan across J&K, Himachal and Uttarakhand; Eastern Himalayan in Sikkim, Darjeeling and NE; Lower Gangetic across UP and Bihar; Middle Gangetic in WB and Jharkhand; Upper Gangetic in Punjab, Haryana, Delhi and western UP; Trans-Gangetic in Assam, Meghalaya and Tripura; Eastern Plateau in Odisha, Jharkhand and WB; Central Plateau in MP, Chhattisgarh and Maharashtra; Western Plateau in Gujarat, Rajasthan and MP; Southern Plateau in AP, Telangana, Karnataka and TN; Eastern Coastal Plains along Odisha and AP; Western Coastal Plains along Kerala, Karnataka, Goa and Maharashtra; Gujarat Plains in Saurashtra-Kathiawar and Kutch; Western Dry in arid Rajasthan, Gujarat, Haryana and Punjab; Island in Andaman-Nicobar and Lakshadweep. The map shows monsoon gradient, soil and slope constraints, and explains cropping patterns: irrigated wheat-rice in Upper Gangetic, paddy in Eastern Coastal, millets in Western Dry, plantation in Western Coastal and Eastern Himalayan, horticulture in Western Himalayan, rice-soybean in Eastern Plateau, groundnut-cotton-pulses in Southern Plateau.

(b) Quad and marine trade Quad’s significance lies in the maritime geography of the Indo-Pacific, where about 60% of global maritime trade moves through Sea Lines of Communication (SLOCs). India, US, Japan and Australia provide a maritime balancing/containment architecture around chokepoints such as the Malacca Strait, through which roughly 80% of China’s oil imports pass, and the Lombok Strait and Makassar Strait as alternative routes. By enhancing maritime domain awareness, interoperability, disaster response and Quad Plus partnerships, including Indo-Pacific Maritime Domain Awareness (IPMDA) initiatives, the Quad helps secure container traffic, rare-earth supply chains and semiconductor logistics. It also counters China’s String of Pearls and BRI maritime corridor. India’s ports, naval presence and partnerships with ASEAN, Japan and Australia strengthen SLOC security, while Quad Plus with France, South Korea and Vietnam widens maritime connectivity. India’s role is distinctive: it does not conduct group Freedom of Navigation Operations (FONOPs), but supports freedom of navigation principles and individual state operations, while offering a non-aligned, rules-based maritime public good.

(c) NFSA evaluation NFSA 2013 converts food access into a legal entitlement: 5 kg per person per month of rice, wheat or coarse cereals at ₹3, ₹2 and ₹1, covering 75% rural and 50% urban populations, with maternity benefit not less than ₹6,000 and mid-day meals for children aged 6–14. It expanded PDS, made women the primary ration card holder, and through One Nation One Ration Card enabled portability. It has helped reduce extreme hunger, reflected in improved Global Hunger Index scores, and stabilised consumption during price shocks, supported by FCI buffer stocks. Yet evaluation must be critical. Exclusion errors persist due to Aadhaar seeding and BPL data gaps; leakages and diversion, reported in some states at around 40%, weaken targeting; the cereal-centric basket limits nutritional diversity; climate shocks to kharif/rabi production threaten supply; and fiscal burden on states constrains implementation. Thus NFSA is a strong entitlement framework but needs better data, nutrition-sensitive food, supply-chain reform and state fiscal support.

Conclusion: Together, agro-climatic regionalisation, Quad-enabled maritime stability and NFSA’s entitlement logic show that India’s food security depends on spatial planning, secure trade routes and inclusive institutional delivery.
