In the Eastern Ghat is a region rich in natural beauty, biodiversity, and cultural heritage. Stretching along the eastern coast of India, this ancient range of hills and mountains is less known than the Western Ghats but equally important in terms of ecology and history. The Eastern Ghats pass through the states of Odisha, Andhra Pradesh, Tamil Nadu, and parts of Karnataka. This area is home to remote tribal communities, unique ecosystems, and scenic landscapes. Its hills are not continuous like the Western Ghats, but broken into discontinuous ranges, making them geologically intriguing and ecologically diverse.
Geographical Features of the Eastern Ghats
The Eastern Ghats run parallel to the Bay of Bengal but are separated from the coastline by a wide stretch of land. Unlike the tall and continuous Western Ghats, the Eastern Ghats are older, more eroded, and made up of disjointed hills. These hills vary in height, with some peaks rising to over 1,600 meters above sea level. The highest peak in the Eastern Ghats is Arma Konda, located in Andhra Pradesh, which reaches approximately 1,690 meters.
Many important rivers, including the Godavari, Krishna, and Mahanadi, cut through the Eastern Ghats, creating deep valleys and fertile plains. These rivers play a crucial role in agriculture and water supply in the surrounding regions. The Ghats also act as a drainage divide and influence local climates by affecting rainfall distribution in the region.

Biodiversity of the Eastern Ghats
The Eastern Ghats are home to a wide range of flora and fauna, many of which are endemic to the region. Although less explored than the Western Ghats, they harbor significant biodiversity and ecological value. The forests here include tropical dry deciduous forests, moist deciduous forests, and evergreen patches in higher elevations.
Several protected areas have been established to preserve the biodiversity of the Eastern Ghats. These include wildlife sanctuaries and national parks such as Sri Venkateswara National Park, Papikonda Wildlife Sanctuary, and Simlipal National Park. These regions support populations of tigers, leopards, elephants, gaur, and various species of deer and birds.

Cultural and Historical Importance
The Eastern Ghats have been home to various tribal communities for centuries. These communities, such as the Kondh, Koya, and Lambadi tribes, maintain unique traditions, languages, and customs. Many of them practice shifting cultivation and depend on forest resources for their livelihood.
The hills are dotted with ancient temples, caves, and historical monuments that reflect the spiritual and architectural heritage of the region. Temples like the Simhachalam Temple in Andhra Pradesh and the Jambunatha Temple in Tamil Nadu attract pilgrims and tourists alike. In addition, prehistoric cave paintings and megalithic burial sites discovered in the region provide insight into early human civilization in South India.

Economic Importance and Agriculture
The Eastern Ghats are important for agriculture, especially in the valleys and plains created by river systems. Crops such as rice, millets, pulses, cotton, and sugarcane are cultivated in this region. The hills are also suitable for growing plantation crops like coffee, spices, and fruits such as mangoes and bananas.
Many tribal communities practice traditional farming and rely on forest products like honey, medicinal plants, bamboo, and wood for income. The Eastern Ghats also contain minerals such as bauxite, limestone, and iron ore, contributing to the local and national economy through mining activities. However, unregulated mining and deforestation pose threats to the delicate balance of the ecosystem.
Common Agricultural Products
- Rice and Millets
- Chillies and Spices
- Coffee and Tea
- Tamarind and Mangoes
- Medicinal Herbs
Environmental Challenges in the Eastern Ghats
Despite their ecological richness, the Eastern Ghats face serious environmental challenges. Deforestation, mining, illegal logging, and habitat fragmentation have led to the loss of biodiversity. Rapid urbanization and infrastructure development are putting pressure on natural landscapes and traditional ways of life.
Climate change is another growing concern. Changes in rainfall patterns, rising temperatures, and increasing frequency of extreme weather events are affecting both natural ecosystems and agriculture. Efforts are being made by government and non-government organizations to promote conservation and sustainable development in the region.
Conservation Efforts
- Creation of biosphere reserves and protected areas
- Afforestation and reforestation programs
- Tribal welfare and community-led conservation
- Eco-tourism development to promote awareness
- Research on biodiversity and climate impacts
