deposits have been discovered in the region in the 21st century. There are two major soil types, forming distinct sub-regions of the plateau. Most of the region with igneous basaltic rock consists of Chernozem, black soil. These soils have a high clay content, retain moisture and are resistant to erosion, but develop cracks during the dry season. The gneiss peneplain region in the low rainfall areas in the eastern vicinity of the Western Ghats consist of infertile red soil.


Geography

Historians have used the term Deccan differently across various time periods. Firishta (16th century), R. G. Bhandarkar (1920), and Richard M. Eaton, Richard Eaton (2005) demarcate the region based on linguistic lines. K. M. Panikkar (1969) defines it as the entire Indian peninsula south of the Vindhyas. Stewart N. Gordon, Stewart Gordon (1998) notes that Deccan is a "relational term" and historically the border of Deccan has varied from Tapti River to the Godavari River, depending on the southern boundary of the northern empires and is used to denote "the area beyond the southern border of a northern-based kingdom" of India. Geographers have defined the extent of Deccan region using various physical features and indices such as rainfall, vegetation, or soil type. As per a broader geographical definition, the region consists of the peninsular Table (landform), tableland lying to the south of the Tropic of Cancer, marked by the Vindhya Range, Vindhya-

owing to the steeper gradient moving from east to west, with only smaller streams flowing in the opposite direction. The streams and rivers give rise to numerous waterfalls in the region. The rivers have been dammed for hydroelectric and irrigation purposes, with major reservoirs spread across the region. The region has largely semi-arid climate in the northern parts and tropical climate in most of the other areas. The summer months of AprilMay are dry and hot with maximum temperatures often rising more than . During the dry summer months of AprilMay, heat builds up on the interior of the Deccan Plaeau, which draws air from the sea. The air, which picks up moisture along the way and flows eastward from the Arabian Sea, is blocked by the Western Ghats. The rising air cools and brings about orographic precipitation along the western coast, which signifies the onset of the monsoon season in June. By the time the air rises above the mountains, it becomes dry, resulting in a rain shadow region with very little rainfall on the leeward side towards the interior of the Deccan plateau. The monsoon winds rounding up the peninsula and moving from the east from the

pass over the Eastern Ghats and bring some rainfall to the eastern region of the plateau. The region receives most of the rainfall during the months of July to September and the rains feed the rivers that flow into basins and then into the Bay of Bengal.


Flora and fauna

There is a wide diversity of plants and animals in the region, resulting from its varied climates and geography. Deccan thorn scrub forests, scrub lands are common in the low rainfall regions with South Deccan Plateau dry deciduous forests, dry deciduous forests found in the southern part of the plateau. The woodlands of the region are older than the Himalayas. The central part of the plateau is covered by woodlands formed by trees such as hardwickia, teak, Albizia lebbek, siris, Anogeissus latifolia, axlewood, Boswellia serrata, boswellia, and Acacia catechu, acacia trees. The region hosts significant populations of endangered Bengal tigers and Indian elephants Other mammals found in the region include gaur, blackbuck, chinkara, four-horned antelope, Wild water buffalo, wild buffalo, and Indian wild dog.


Demographics

The largest linguistic group in the region is the Dravidian family of languages, of approximately 73 languages.

Evidence of prehistoric religion in the region comes from scattered Mesolithic rock paintings depicting dances and rituals, such as the Kupgal petroglyphs of eastern Karnataka, at South Asian Stone Age, Stone Age sites. Hinduism is the major religion today in the region. The total fertility rate in the region was less than the Sub-replacement fertility, population replacement level and as a result, the proportion of the population of the region to India's total population has declined in the last four decades. The economies of the states in the region registered a growth higher than the national average over the past three decades. While the states have improved in some of the socio-economics, socio-economic metrics, there is wide disparity within the region.


Economy

Agriculture is often difficult in low rainfall areas, which require additional irrigation facilities while it is more feasible in the river valleys. Agriculture is still the primary occupation in the region. Rice is the staple food and major crop in the region.
