The Eastern Ghats, a discontinuous mountain range running parallel to India's eastern coast from Odisha to Tamil Nadu, is characterized by a diverse landscape encompassing hills, plateaus, valleys, and coastal plains. The land utilization patterns in this region are shaped by its varied topography, climate, resource endowment, and the presence of significant tribal populations.

Characteristics of Land Utilisation in the Eastern Ghats:

1. Forest Land: A substantial portion of the Eastern Ghats is covered by forests, primarily tropical moist deciduous and dry deciduous types. These forests are crucial for biodiversity, ecological balance, and support the livelihoods of numerous tribal communities who depend on minor forest produce, shifting cultivation, and forest-based resources.
2. Agriculture:
   • Shifting Cultivation (Podu/Jhum): Prevalent in the hilly, tribal-dominated interior areas, this traditional slash-and-burn method involves cultivating a plot for a few years and then moving to a new one, allowing the previous plot to regenerate. Crops like millets, pulses, and some vegetables are grown.
   • Rainfed Agriculture: In the foothills and plains, rainfed agriculture is dominant, with crops like rice, maize, millets, pulses, and oilseeds being cultivated, largely dependent on monsoon rainfall.
   • Horticulture and Plantations: Specific areas, particularly at higher altitudes (e.g., Araku Valley in Andhra Pradesh), are known for horticulture (mango, cashew, jackfruit) and plantations of coffee, pepper, and sometimes rubber.
3. Mining: The Eastern Ghats are rich in mineral resources, including bauxite, iron ore, manganese, limestone, and chromite. Consequently, mining activities, particularly open-cast mining, are a significant land use, leading to large-scale land alteration.
4. Pastoralism: While not as dominant as in other regions, some communities practice livestock rearing, utilizing forest fringes and grasslands for grazing.
5. Settlements: Human settlements range from scattered tribal villages in the remote hills to more concentrated agricultural villages and towns in the valleys and plains.
6. Water Bodies: The region is crisscrossed by major rivers like the Godavari, Krishna, Mahanadi, and their tributaries, which support irrigation and provide water resources, leading to the development of reservoirs and dams.

Recent Threats to Land Utilisation Methods in the Region:

1. Deforestation and Forest Degradation: This is a primary threat, driven by:
   • Mining: Extensive open-cast mining for bauxite and other minerals leads to massive forest loss, habitat destruction, soil erosion, and water pollution (e.g., bauxite mining in Niyamgiri hills, Odisha).
   • Encroachment: Forest land is encroached upon for agriculture, settlements, and infrastructure projects.
   • Unsustainable Shifting Cultivation: Increased population pressure and reduced fallow periods make traditional shifting cultivation unsustainable, leading to faster forest degradation.
   • Illegal Logging: Timber extraction contributes to forest loss.
2. Climate Change: Erratic rainfall patterns, increased frequency of droughts and floods, and rising temperatures directly impact rainfed agriculture and forest ecosystems, threatening traditional farming practices and crop yields.
3. Land Alienation and Displacement: Large-scale development projects (dams, industrial corridors, Special Economic Zones) often lead to the displacement of tribal communities and the conversion of forest and agricultural land. Land grabbing by non-tribals, exploiting legal loopholes or lack of land records, is also a significant issue.
4. Pollution: Mining activities cause severe water and soil pollution from waste discharge. Industrial units in the foothills contribute to air and water pollution, impacting agricultural productivity and human health. Agricultural runoff with pesticides and fertilizers also contaminates water bodies.
5. Biodiversity Loss: Habitat destruction due to deforestation, mining, and unsustainable land use practices leads to a significant loss of the region's rich biodiversity, including endemic species.
6. Human-Wildlife Conflict: As forest habitats shrink and fragment, human-wildlife conflicts (e.g., elephant-human conflicts) are on the rise, impacting both livelihoods and wildlife conservation efforts.
7. Naxalism/Maoist Insurgency: In some parts of the Eastern Ghats, the presence of Naxalite groups affects governance, development initiatives, and sustainable land management, often exploiting local grievances related to land and resources.
8. Unsustainable Agricultural Practices: Over-reliance on chemical fertilizers and pesticides, coupled with a lack of soil conservation measures, degrades agricultural land over time.

These threats collectively endanger the ecological balance, traditional livelihoods, and long-term sustainability of land utilization in the Eastern Ghats, necessitating urgent and integrated conservation and development strategies.
