Peninsular Plateau of India, Geography, Map, Rivers and Major States

The Peninsular Plateau almost make up three-fourths of India, and it is the oldest, stable formation in nature. As a fragment of the Indian Shield, it consists of igneous and metamorphic rocks dating back to Precambrian time and has undergone very little tectonic activity for millions of years. The northern edge of the plateau is defined by the Aravalli Range, with central India being occupied from north to south by the Vindhya and Satpura ranges and then running along both coasts up to Kanyakumari. Western Ghats (Sahyadri) in the west and the Eastern Ghats.

The Peninsular Plateau, a vast expanse of land with rich minerals and forests as well as fertile soils, supplies many major rivers and is the backbone of farming, industry and economy in India.

Peninsular Plateau of India Features

The oldest and most stable physical division of India is the Peninsular Plateau. This is a triangular tableland formed from an ancient crystalline igneous and metamorphic rock contact area. Covering nearly 16 lakh sq. 1 million sq, km, this constitutes nearly half the area of India and its mineral & natural resources.

Key Features of the Peninsular Plateau

• Oldest Landmass: The earth’s oldest geological formations are of early Precambrian age.
• Triangular Form: The triangular form of the plateau has its base to the north and at Kanyakumari towards the south.
• Average Elevation: It has an elevation of 600–900 metres (2,000–3,000 ft).
• Stable Geographical Structure: It contains parts of ancient Gondwana Land and is tectonically stable with a minimum occurrence of seismic movement.
• Rock Type: Mainly igneous and metamorphic rocks such as granite, gneiss, basalt and schist;
• Limits: Surrounded in the upper west by the Aravalli Range, toward the east middle by the Vindhya and Satpura Ranges, and along both flanks by the Western Ghat and Eastern Ghat.
• Parent Categories: These are divided into the Central Highlands and Numerically Deccan Plateaus.
• River Systems: The major rivers include the Narmada and Tapi in the west, while the Godavari, Krishna, Kaveri and Mahanadi drain into the Bay of Bengal.
• Rich in minerals like coal, iron ore, manganese, bauxite, mica and limestone and with copper once found as well, it’s the mineral heartland of India.

Challenges of the Peninsular Plateau of India

• Land Degradation: Soil erosion, deforestation, overgrazing, and unsustainable land use have resulted in the loss of soil resources; degraded soils today are less fertile and productive.
• Environmental Cost of Mining: Coal, iron ore, bauxite, limestone and manganese mining causes deforestation (destruction of vegetation), land degradation (soil erosion), air pollution (which raises the cost of sand masks for breathing) through dust emissions as well as water contamination and habitat destruction.
• Water Scarcity: Lack of proper and balanced rainfall, frequent droughts, and reduced groundwater levels lead to scarcity of water for farms, industries, and domestic uses.
• This erosion of the soil base, especially wind and water erosion related to plateau slopes and degraded forests, deteriorates the quality and productivity of agricultural land.
• Deforestation: The expansion of mining, agriculture, infrastructure and urbanisation has led to reduced forest cover and biodiversity.
• Loss of Biodiversity: Areas with ecological sensitivity such as the Western Ghats and Eastern Ghats are vulnerable to habitat fragmentation and loss of endemic species.
• Climate Change: Climate change is making high temperatures, unstable monsoons, severe droughts and extreme events negatively impact agriculture, forests and water.
• Landslides: Some areas of the Western Ghats are highly susceptible to landslips as a result of heavy rainfall, quarrying for stone aggregates, road building as well as deforestation.
• Groundwater depletion: This problem arises when groundwater is being used for irrigation and industrial purposes more than its replenishment, resulting in declining groundwater levels in many plateau regions.
• Forced displacement: Mining and the construction of large infrastructures often result in forced displacement for tribal communities and threaten their traditional means of livelihood.
• Accelerated Urbanisation: Pressure on all types of natural resources and fragile ecosystems is booming amidst rapid industrialisation and urban expansion.
• What are Forest Fires: Dry climatic conditions and human activities are causing seasonal forest fires, which cause ecological and economic losses.
• Conservation of Critical Minerals: Access to critical minerals such as lithium is growing due to the transition away from fossil fuels, which requires a focus on balancing mineral extraction with environmental protection and sustainable mining practices.
• Infrastructure Bottlenecks: Despite improvements, remote areas in plateau regions remain poorly connected by transport and irrigation networks and market access.
• Sustainable Resources Management: Due to heavy and rapid exploitation of mineral, water, and forest resources for economic development, sustainable management of these through the mining path from mine-to-metal production is still a significant policy challenge.
