India’s demographic and ecological diversity is reflected in distinct regional socio-economic adaptations, land-use patterns, and agrarian practices.

Distribution and Socio-Economic Disparities: Scheduled Castes vs Scheduled Tribes

The spatial distribution of Scheduled Castes (SCs) and Scheduled Tribes (STs) 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. 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.

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.

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, monoculture commercial plantations (coffee and rubber in areas like Araku and Shevaroy hills), 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. Second, the unscientific expansion of wind energy projects along high-ridge summits in the Tamil Nadu Ghats disrupts ridge ecology and alters local microclimates. 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.

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, 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; and earns valuable foreign exchange through the commercial export of dairy commodities, including skimmed milk powder, butter, and indigenous milk preparations.

Sustainable regional development in India requires addressing the historical marginalisation of SC and ST communities, arresting ecological and land degradation in sensitive zones like the Eastern Ghats, and strengthening the livestock economy to foster inclusive and climate-resilient rural growth.
