(a) Distribution and Socio-Economic Disparities: Scheduled Castes vs Scheduled Tribes

Census 2011 counted SCs at 16.6% and STs at 8.6% of India's population, but their spatial distribution differs fundamentally due to historical, environmental, and socio-cultural factors. SCs are predominantly concentrated in the fertile alluvial tracts of the Indo-Gangetic plains (such as Uttar Pradesh, Bihar, and West Bengal) and coastal deltas. Historically, their distribution followed the caste-based agrarian hierarchy of settled valley agriculture, where they formed the core agricultural labour force; hence SCs are spread through almost every district, with the highest proportion in Punjab (about 32%) and the largest numbers in Uttar Pradesh. Conversely, STs are concentrated in the forested, rugged uplands of the Central Tribal Belt (Madhya Pradesh, Chhattisgarh, Jharkhand, and Odisha) and the North-Eastern hill states. This pattern stems from geographical isolation, historical retreat from expanding agrarian states, and colonial forest policies that demarcated reserve forests, confining tribal communities to marginal uplands. STs are therefore highly clustered: they form over 90% of the population in Mizoram and Lakshadweep, yet are almost absent from Punjab, Haryana and the Gangetic core.

In socio-economic terms, both groups share similarities in high poverty incidence, educational deprivation, and political under-representation. However, their challenges differ in structural dimensions:

Spatial Exclusion versus Physical Isolation: SCs reside in mainstream, multi-caste villages but endure social exclusion, untouchability, residential segregation on village peripheries, and the historical indignity of manual scavenging. STs, by contrast, face physical and infrastructural isolation in remote, hilly settlements with poor road connectivity, inadequate healthcare access, and weak institutional reach.

Resource and Livelihood Insecurity: Rural SCs suffer predominantly from acute landlessness, functioning primarily as landless agricultural or unorganised wage labourers. In contrast, STs, who traditionally depended on customary rights over common property resources, face large-scale developmental displacement, alienation of ancestral lands for industrial or mining projects, and legal curbs on shifting cultivation (podu or jhum) due to rigid forest conservation regimes, which the Forest Rights Act, 2006 and PESA, 1996 seek to redress; the 75 Particularly Vulnerable Tribal Groups face the sharpest deprivation. For SCs, the corresponding safeguards are the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989 and the ban on manual scavenging (2013 Act).

(b) Land Utilisation and Recent Threats in the Eastern Ghats

The Eastern Ghats, a discontinuous chain of relict highlands running across Odisha, Andhra Pradesh, and Tamil Nadu, exhibit specific land utilisation characteristics: traditional shifting cultivation (podu) on upper slopes, degraded dry deciduous and scrub forest patches, commercial plantations (coffee in Araku valley and the Shevaroy hills, cashew and eucalyptus on lower slopes), resource-extractive mining corridors, and sparse, rainfed settled agriculture in narrow valley bottoms.

Recent threats undermining sustainable land utilisation in this region include: First, intense open-cast bauxite and iron-ore mining across the Odisha–Andhra Pradesh belt causes large-scale topsoil removal, habitat fragmentation, and aquifer depletion; the Niyamgiri bauxite proposal, rejected by Dongria Kondh gram sabhas in 2013, shows the conflict with customary land use. Second, large dam and reservoir projects such as Polavaram submerge tribal villages and valley farmland across Andhra Pradesh, Odisha and Chhattisgarh, while red sanders smuggling degrades the Seshachalam forests. Third, rapid urban sprawl and industrial corridor expansion along the Chennai–Bengaluru axis induce heavy land conversion, consuming foothill commons and fertile agricultural fringes. Fourth, climate-induced rainfall variability, marked by intense dry spells and irregular monsoon bursts, accelerates soil erosion on degraded slopes, rendering rainfed valley farming increasingly precarious.

(c) Challenges and Bovine Contribution in the Dairy Sector

India’s dairy sector faces multiple structural challenges: low average milk productivity among non-descript indigenous breeds; chronic deficits in both green and dry fodder; inadequate coverage of artificial insemination (AI) and cold-chain infrastructure in rural hinterlands; seasonal farm-gate price volatility; and stark regional imbalances, with well-developed cooperative networks in western and southern India contrasting sharply with weak, unorganised markets in eastern and central states.

Despite these constraints, India is the world's largest milk producer (about a quarter of global output), milk is its largest agricultural commodity by value, and the 20th Livestock Census (2019) counted about 303 million bovines (193 million cattle and 110 million buffaloes). The bovine population provides critical multi-dimensional contributions: It underpins rural livelihood security by serving as a year-round buffer against crop failure; supplies organic manure and bio-fertiliser vital for soil health and sustainable agriculture; provides draught animal power essential for ploughing and rural haulage in the fragmented, smallholder landscapes of eastern and peninsular India; supports roughly eight crore rural households, many of them landless and women-led, whose income is spread across the year; and earns some foreign exchange through exports of skimmed milk powder, butter and ghee, though exports remain small relative to production. Operation Flood and the NDDB-led cooperative model (Amul) and the Rashtriya Gokul Mission for indigenous breeds such as Gir, Sahiwal and Murrah buffalo are the main institutional responses.
