The total population of the state is 84,79,562 which live in 16,826 villages. The population is multi-ethnic belonging to varied cultural origins. Around 36.5% of the population is Below Poverty Line (BPL). PHYSIOGRAPHIC ZONES OF UTTARAKHAND Major Physiographic zones The Uttarakhand Himalayas are divided into the following distinct non-montane and montane physiographic zones (Map -5 State Map showing different Altitude Zones) as follows: a. Non-montane i. Bhabhar: This is a level surface zone at the foothills of the Himalayas 34 km wide where the Himalayan torrents rush down from the steep slopes and disappear under boulders and gravels due to the extremely porous soil type of Bhabhar. ii. Tarai: Situated below the Bhabhar and parallel to it, the Tarai is a marshy and damp tract (once 80-90 km wide) containing fertile soils with good water retention capacity. b. Montane i. Sub-Himalayas: Called Sub-Himalayas because it possesses the least of Himalayan features. It consists of two zones, the Shivaliks - the youngest of the Himalayan ranges and the Doon (flat longitudinal structural valleys) to the north of Shivaliks. The Shivaliks extend in a narrow varying width of 6 to 30 km with altitudes of 300 to 1000 m. ii. Mid Himalayas : This zone extends in a varying width of 60-90 km in an abrupt rise in elevation between 1000 m to 3000 m. It contains two types of physiographic sub-units The Himachal ranges The Himachal valleys and lake basins. iii. Greater Himalayas: This zone has a varying width of 40-60 km. The altitude varies between 3000-7000 m. Except for lower valleys, this zone is perpetually covered with snow hence called Himadri. The region covers glacial landforms above 3000 m. 8

iv. Trans-Himalayas: Also known as the Tethys Himalayas and Indo-Tibet plateau, the region is in the rain-shadow of the Greater Himalayas and is therefore a cold desert. It slopes down to the Yarlungtsangpo (Brahmaputra) river valley in Tibet. The various physiographic zones of the State are classified into different soil types, crops produced, district wise, alongwith the rainfall distribution in these zones in the following table.
