Location, Relief and Physiographic Regions
Location, Extent and Administrative Set-up of UP
Chapter Overview
Chapter 1 sets out where Uttar Pradesh lies and what its land is made of: its location, extent and administrative set-up, and then its relief, rock structure and regions. UP covers 2,40,928 sq km and is the fourth largest State by area (Government of UP, 2022), yet it holds 16.5% of India's people (Census 2011).
The first topic fixes the frame: position, neighbours, divisions and districts. The second explains the three physical divisions, Bhabar–Terai, Ganga plain and southern plateau, and the five regions built on them, whose farming, industry and culture differ as much as their relief.

A State's location is its place on the globe and among its neighbours; Uttar Pradesh lies in north India, on the fertile Ganga plain between the Himalayan foothills and the Vindhyan ranges. It covers 2,40,928 sq km and is the fourth largest State by area (Government of UP, 2022).
Position, Extent and Neighbours
- Position: UP occupies the central part of the Indo-Gangetic plain, so almost the whole State lies on flat, fertile alluvium drained by the Ganga system; e.g. only Bundelkhand and the Vindhyan hills in the south rise above the plain (see Topic 2); national frame: see GS-1 Geography, Physiography of India.
- Latitude and longitude: the State begins at 23°52′N in the south, just north of the Tropic of Cancer, and spans longitudes 77°3′E to 84°39′E (Government of UP, 2020); e.g. extreme districts: Saharanpur (north), Shamli (west), Ballia (east) and Sonbhadra (south).
- Area and rank: UP is the fourth largest State by area and the largest by population, so its land carries a far heavier load of people than most States; e.g. 2,40,928 sq km, after Rajasthan, Madhya Pradesh and Maharashtra (Government of UP, 2022); UP has 16.5% of India's people (Census 2011).
- Neighbours: eight States, Delhi and Nepal touch UP; Nepal lies along the northern Terai and Madhya Pradesh shares the longest boundary, from Agra to Sonbhadra; e.g. Uttarakhand, Himachal Pradesh, Haryana, Delhi, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, Bihar (Government of UP, 2020, 2022); Nepal-border districts: Pilibhit to Mahrajganj.
Divisions, Districts and the Capital
- Administrative units: the State is run through divisions under Commissioners and districts under District Magistrates, with tehsils and development blocks below them; e.g. 18 divisions, 75 districts, 351 tehsils and 826 development blocks (UP DES, 2022); State administration: see GS-5 Ch 9.
- Capital and legal basis: Lucknow, near the centre of the plain, is the capital; the State Government creates or alters divisions, districts and tehsils under the UP Revenue Code; e.g. UP Revenue Code, 2006; Census 2027 houselisting in UP ran in May–June 2026 on this district frame (PIB, 2026).
| Part of UP | Divisions (18) |
|---|---|
| West | Saharanpur, Meerut, Moradabad, Bareilly, Aligarh, Agra |
| Centre | Lucknow, Kanpur |
| East | Ayodhya, Devipatan (HQ Gonda), Basti, Gorakhpur, Azamgarh, Varanasi, Mirzapur, Prayagraj |
| South (Bundelkhand) | Jhansi, Chitrakoot Dham (HQ Banda) |
Problems of Size and Position
UP's central place in north India is an asset, but its large size and lack of a coast also bring costs that smaller or coastal States do not bear.
- Landlocked State: UP has no coastline, so its farm and factory goods travel long distances by road and rail to reach ports on either coast; e.g. the Western Dedicated Freight Corridor from Dadri now carries goods to the Gujarat and Mumbai ports; see GS-6 Industry Ch 2, Topic 3.
- Scale of administration: very large district populations stretch officers and public services, which is why new districts have been carved out over the decades; e.g. Prayagraj had 59.54 lakh people (Census 2011); UP had 70 districts in 2006-07 and 75 by 2014-15 (UP DES, 2016).
Management and Significance of UP's Position
- Strategic corridor: UP's flat plain lies on the Delhi–Kolkata route, so trunk highways, main railway lines and industrial corridors all cross the State; e.g. Amritsar–Kolkata and Delhi–Mumbai Industrial Corridors; Eastern Dedicated Freight Corridor via Kanpur and Prayagraj; expressways: see GS-6 Industry Ch 2, Topic 2.
- Nepal border: the open border joins UP to Nepal through trade, family and pilgrim ties, and calls for joint watch on smuggling and floods; e.g. Sonauli (Mahrajganj) road crossing; Kapilvastu–Lumbini Buddhist link; border security: see GS-5 Ch 14, Topic 5.
Used through corridors, border trade and well-sized districts, UP's central position and large size can become strengths rather than burdens.

Relief, Structure and Physiographic Regions of UP
Within these borders the land falls from the Himalayan foothills to the Ganga plain and rises again to the southern uplands; a physiographic region is a tract with a common relief, rock and drainage. UP holds most of the middle Ganga plain, from Narora to Ballia (India-WRIS, 2026), and its density of 829 persons per sq km is more than twice India's 382 (Census 2011).
Three Physiographic Divisions of UP
- Bhabar and Terai: the Bhabar is a narrow pebbly belt at the Shivalik foot where streams sink underground; south of it they re-emerge in the moist, marshy Terai; e.g. Bhabar widest in the west near Saharanpur; Terai wider in the east along the Nepal border, with sal forest and tall grass; protected areas: see GS-6 Environment Ch 3, Topic 1.
- Ganga plain: the great plain, built of silt laid by the Ganga, Yamuna, Ghaghara and their tributaries, slopes gently south-east and covers most of the State; e.g. Ganga–Yamuna doab, the land between two rivers, in the west; the Yamuna joins the Ganga at the Sangam, Prayagraj (NMCG, 2026); rivers: see Ch 2, Topic 2.
- Bhangar and khadar: the plain has older bhangar uplands with kankar above flood level and low khadar flood plains that floods renew with fresh silt; e.g. khadar along the Ganga and Yamuna banks; bhur sand ridges on western uplands; usar–reh patches in the bhangar: see Ch 3, Topic 1.
- Southern plateau: south of the Yamuna and Ganga, the Bundelkhand upland and the Vindhyan hills form rocky, uneven land with thin soils and deep ravines; e.g. Jhansi, Lalitpur, Mahoba and Banda (Bundelkhand); Mirzapur and Sonbhadra (Vindhyan and Kaimur hills); Yamuna–Chambal ravines of Etawah and Jalaun.
| Basis | Bhangar | Khadar |
|---|---|---|
| Age | Older alluvium | Newer alluvium, laid in each flood season |
| Position | Upland terraces above flood level | Low flood plains along the river channels |
| Texture | Clayey, with kankar (lime nodules) | Fine silt, sand and clay, without kankar |
| Fertility | Less fertile; usar–reh patches in places | More fertile; renewed by floods |
| Example | Doab uplands between the rivers | Flood plains of the Ganga and Yamuna |
Rock Structure and Earthquake Risk
- Old block and young plain: the south is part of the ancient Peninsular block; the north is a foredeep, a sinking trough before the Himalaya, filled with thick alluvium; e.g. Archaean Bundelkhand granite-gneiss of Jhansi and Lalitpur; Proterozoic Vindhyan sandstone of Chunar (Mirzapur); Gondwana coal of Singrauli (Sonbhadra); minerals: see Ch 3, Topic 3.
- Seismic zones: Himalayan thrusts and the buried ridges and faults under the plain make the Terai and the north-west the most earthquake-prone parts of UP; e.g. high-damage-risk Zone IV: the Terai belt and 11 western districts, Saharanpur, Muzaffarnagar, Baghpat, Bijnor, Meerut, Ghaziabad, Gautam Buddh Nagar, Amroha, Rampur, Moradabad and Bulandshahr; weak zones: Delhi–Haridwar Ridge, Moradabad Fault (UP SDMA, c. 2005); see GS-3 Disaster Management Ch 3, Topic 1.
| Rock system | Age | Main rocks | Where in UP |
|---|---|---|---|
| Bundelkhand granite-gneiss | Archaean, the oldest | Granite, gneiss | Jhansi, Lalitpur, Mahoba, Hamirpur |
| Vindhyan Supergroup | Proterozoic | Sandstone, shale, limestone | Mirzapur, Sonbhadra, south Prayagraj, Chitrakoot |
| Gondwana | Palaeozoic (Permian) | Sandstone and shale with coal seams | Singrauli coalfield, Sonbhadra |
| Shivalik | Tertiary | Sandstone, clay, conglomerate | Shivalik foothills of Saharanpur |
| Ganga alluvium | Quaternary, the latest period | Clay, silt, sand, gravel | The whole Ganga plain |
Geographical Regions and their Significance
- Five regions: relief, soil and history divide UP into Western UP, Central UP (Awadh), Eastern UP (Purvanchal), the Terai and Bundelkhand; e.g. Meerut and Agra (west); Lucknow and Kanpur (centre); Varanasi and Gorakhpur (east); Bahraich and Kheri (Terai); Jhansi and Banda (Bundelkhand); agro-climatic zones: see GS-6 Agriculture Ch 1, Topic 1.
- Geographical significance: deep alluvium and assured water carry dense populations on the plains, while the rocky, dry south supports far fewer people; e.g. density: Varanasi 2,395 and Lucknow 1,816 against Lalitpur 242 persons per sq km (Census 2011); see Ch 4, Topic 1.
- Economic significance: the west leads in sugarcane, wheat and NCR industry, the centre in government and manufacturing, the east and Terai in rice and migrant labour; e.g. sugar belt of Saharanpur, Muzaffarnagar and Meerut; Noida and Ghaziabad; Lucknow and Kanpur; Bundelkhand stone and minerals; disparities: see GS-6 Economy Ch 5, Topic 2.
- Pilgrim centres of the plain: the Ganga plain holds the chief centres of Hindu pilgrimage, and its river fairs draw crowds counted in crores; e.g. the Maha Kumbh at the Triveni Sangam, Prayagraj, in January–February 2025 drew over 66 crore devotees (PIB, 2025); the Kumbh is on the UNESCO intangible heritage list; Kashi, Ayodhya, Mathura–Vrindavan.
- Buddhist and Bundelkhand heritage: the Terai and eastern plain hold the main sites of the life of the Buddha, while Bundelkhand keeps its own forts, temples and ballads; e.g. Kapilvastu, Shravasti, Sarnath, Kushinagar, Kaushambi and Sankisa (MEA, 2024); Kalinjar fort (Banda), Devgarh temples (Lalitpur), Alha–Udal ballads of Mahoba; tourism: see GS-5 Ch 6, Topic 4.
| Region (e.g. districts) | Physical setting | Economic significance | Cultural significance |
|---|---|---|---|
| Western UP: upper doab, Rohilkhand, Braj (Meerut, Saharanpur, Bareilly, Agra) | Bhangar uplands and bhur ridges of the Ganga–Yamuna doab | Sugarcane, wheat; NCR industry at Noida and Ghaziabad | Braj of Mathura–Vrindavan; Mughal Agra |
| Central UP: Awadh (Lucknow, Kanpur, Unnao, Rae Bareli) | Level Ganga–Gomti plain; usar–reh patches | Capital and services at Lucknow; industry at Kanpur | Awadhi speech; Nawabi culture of Lucknow |
| Eastern UP: Purvanchal (Varanasi, Gorakhpur, Ayodhya, Ballia) | Low khadar plain of the Ganga and Ghaghara; Vindhyan hills in Mirzapur and Sonbhadra | Rice and wheat on small farms; floods; migrant labour | Kashi, Ayodhya, the Sangam; Sarnath, Kushinagar; Bhojpuri |
| Terai (Pilibhit to Mahrajganj) | Moist, marshy belt below the Bhabar; sal and tall grass | Rice, sugarcane; forests and wildlife | Kapilvastu, Shravasti; Tharu people |
| Bundelkhand (Jhansi, Lalitpur, Banda, Mahoba, Chitrakoot) | Granite-gneiss upland; red and black soils; ravines | Rain-fed pulses and oilseeds; stone and minerals; drought | Kalinjar, Devgarh, Chitrakoot; Alha–Udal |
Problems of UP's Regions
Each region's relief brings its own hazard, so UP's problems are regional rather than uniform: too much water in the north-east, too little in the south and overdrawn aquifers in the west.
- Floods in the Terai and east: rivers from Nepal and Uttarakhand spill over the flat khadar and Terai, so floods and waterlogging return to the north-east almost every year; e.g. Ghaghara and Rapti plains of Bahraich and Gorakhpur; about 30% of UP is flood-prone (UP SDMA, c. 2005): see Ch 2, Topic 1.
- Drought in the south: thin soils over hard rock hold little water, so Bundelkhand and the Vindhyan belt suffer drought, low yields and out-migration; e.g. Lalitpur is chronically drought-affected (UP SDMA, c. 2005): see Ch 2, Topic 1; Bundelkhand as a backward region: see GS-6 Economy Ch 5, Topic 2.
- Groundwater stress in the west: heavy tube-well irrigation of paddy and sugarcane draws down the alluvial aquifers of western UP faster than rain can refill them; e.g. stage of groundwater extraction: UP 70.0% vs India 60.6% (CGWB, 2025); see Ch 2, Topic 4.
Management and Significance of the Regions
- Region-wise water plans: canals for the Terai and eastern plain and groundwater rules for the overdrawn west fit water policy to the relief of each region; e.g. Saryu Nahar National Project (2021) irrigates over 14 lakh ha in nine Terai and eastern districts (PIB, 2021); UP Ground Water Act, 2019; see Ch 2, Topics 3 and 4.
- Earthquake-safe building: towns of the Zone IV belt need earthquake-resistant buildings, retrofitting of schools and hospitals and careful use of soft alluvial ground; e.g. BIS code IS 1893 for earthquake-resistant design, needed in Meerut, Ghaziabad, Moradabad and the Terai towns; see GS-3 Disaster Management Ch 3, Topic 1.
Planning by region, with flood control in the Terai and east, groundwater limits in the west and water harvesting in Bundelkhand, can make UP's varied relief a base for balanced growth.
