Nepal’s official area is 147,516 square kilometres on the southern flank of the central Himalaya, forming a landlocked strip of South Asia between China’s Tibet Autonomous Region to the north and India to the east, south, and west. Roughly 800 kilometres from east to west but usually only 150–250 kilometres north to south, it rises abruptly from the low Tarai plain near the Indian border to the world’s highest mountains. Kathmandu, the capital, occupies an intermontane basin in the middle hills. Three broad belts organize the landscape: the subtropical Tarai and adjoining Siwalik foothills; the dissected middle hills and Mahabharat range; and the high Himalaya, where Mount Everest reaches 8,848.86 metres on the China border. Major river systems, including the Koshi, Gandaki/Narayani, Karnali, and Mahakali, descend southward through steep gorges before spreading across the plains, linking Himalayan snow and monsoon rainfall to the Ganges basin.
Climate changes over short distances because elevation, slope exposure, and the summer monsoon matter more than latitude alone. The Tarai has hot, humid summers and mild winters, while Kathmandu and many middle-hill valleys have warm monsoon summers and cooler, dry winters. Temperatures fall sharply with altitude into alpine and nival conditions in the high Himalaya. Most precipitation arrives between June and September; eastern and windward mountain slopes are generally wetter than the trans-Himalayan districts of Mustang and Dolpo, which lie in a pronounced rain shadow. This seasonality structures cropping calendars, river discharge, road reliability, and hydropower output. It also concentrates risk: intense monsoon rain triggers floods, debris flows, and landslides, while erratic rainfall can produce drought in agricultural districts. Glacier retreat and unstable glacial lakes add longer-term hazards in high basins, and the Kathmandu Valley and Tarai face serious air-pollution episodes. Nepal’s active tectonic setting creates a separate but recurrent earthquake threat.
These gradients support ecosystems ranging from riverine grasslands and sal forests in the Tarai through subtropical and temperate broadleaf forests, conifers, alpine meadows, and sparsely vegetated high-mountain terrain. The protected-area system spans many of these zones, including Chitwan National Park, Sagarmatha National Park, and the large Annapurna Conservation Area. National forest inventories place forest and other wooded land at roughly 45 percent of the territory, although definitions and survey dates matter, and community forestry has helped restore woodland in many middle-hill districts. Farming remains closely tied to topography. Irrigated Tarai fields produce much of the rice, wheat, sugarcane, and oilseeds, while hill agriculture relies heavily on terracing for maize, millet, vegetables, and fodder. Tea and large cardamom are important in the east, with horticulture expanding in selected uplands. Steep slopes, fragmented holdings, erosion, wildlife conflict, and labor migration all shape rural livelihoods.
Human settlement in the Kathmandu Valley is documented from antiquity, but Nepal’s early political history is better understood as a succession of regional societies than as a continuous modern nation-state. The Licchavi kingdom, flourishing from about the fourth to ninth centuries CE, left inscriptions, temples, and sculpture showing strong connections with northern India while the valley also served as a conduit toward Tibet. Later Thakuri rulers were followed by the Malla period, beginning around the thirteenth century, when Kathmandu Valley urbanism, Newar craftsmanship, and long-distance commerce developed within a wider Himalayan trading world. After the late fifteenth century the valley was divided principally among Kathmandu, Patan, and Bhaktapur, whose courts competed through architecture, religious patronage, and trade. Buddhism and Hinduism interacted closely in the valley, while Tibetan Buddhist cultures developed across high Himalayan communities and Indo-Gangetic networks remained influential in the Tarai. In the eighteenth century the hill principality of Gorkha, under Prithvi Narayan Shah, expanded east and west and captured the Kathmandu Valley in 1768–69, creating the political core of the Shah kingdom from which most of modern Nepal developed.
Shah expansion brought Nepal into conflict with neighboring Himalayan powers and the British East India Company. The Anglo-Nepalese War of 1814–16 ended with the Treaty of Sugauli, under which Kathmandu ceded extensive territory and accepted a British resident; much of the present southern and western boundary emerged from that settlement and later adjustments. Nepal nevertheless remained formally independent rather than becoming a European colony. After the 1846 Kot massacre, the Rana family established a hereditary prime-ministerial oligarchy that reduced the Shah monarchs to limited political roles and governed until 1951. Subsequent decades alternated between parliamentary experiments and royal control: King Mahendra dissolved the elected government in 1960, and the partyless Panchayat system lasted until the 1990 People’s Movement restored multiparty constitutional rule. A Maoist insurgency from 1996 to 2006 exposed deep rural, caste, regional, and governance grievances and ended through the Comprehensive Peace Agreement. The monarchy was abolished in 2008. Nepal’s 2015 constitution then institutionalized a secular federal democratic republic, redistributing authority among federal, provincial, and local governments while leaving representation, citizenship, and centre-periphery power politically significant.
Nepal’s economy is dominated by services, while agriculture remains a major source of livelihoods and manufacturing is comparatively small. National estimates for fiscal year 2025/26 put real GDP growth at about 3.85 percent at purchasers’ prices, with agriculture expanding slowly and electricity among the fastest-growing sectors. The structural picture is more important than a single growth rate: millions of Nepalis work abroad, and remittances finance household consumption, education, construction, and imports while easing the foreign-exchange constraint. Tourism supplies service exports and employment, especially in Kathmandu, Pokhara, Himalayan trekking regions, and pilgrimage centres, but is sensitive to shocks. Hydropower has become a more consequential source of investment and export revenue as generating capacity and cross-border transmission expand. Merchandise exports remain narrow relative to imports; India is by far the largest trading partner, and FY2025/26 exports were strongly influenced by refined edible-oil re-exports alongside cardamom, jute goods, carpets, tea, and manufactured products. Limited job creation, uneven productivity, import dependence, and regional inequality remain central development constraints.
The 2021 National Population and Housing Census counted 29,164,578 people, with average density of about 198 people per square kilometre and annual population growth of 0.92 percent over the preceding decade; UN estimates placed the population at roughly 29.6 million in 2025. Distribution is highly uneven. The Tarai and inner valleys support dense agricultural and urban settlement, while many high Himalayan districts are sparsely populated and some middle-hill areas have experienced substantial out-migration. Kathmandu Valley is the dominant metropolitan concentration and administrative centre, while Pokhara, Bharatpur, Biratnagar, Birgunj, Butwal, Janakpur, and Nepalgunj anchor regional economies and transport corridors. Administrative urban status does not always correspond to continuous city form because many municipalities contain substantial rural territory. Under the federal system, Nepal is divided into seven provinces, 77 districts, and 753 local levels. Its population encompasses many caste, ethnic, regional, and Indigenous identities whose distribution reflects ecology, migration, and historical political incorporation.
Nepali, written in Devanagari, is the official federal language and principal lingua franca, but multilingualism is fundamental to the country’s social geography. The 2021 census recorded 124 mother tongues; Nepali was the first language of 44.9 percent of the population, while Maithili, Bhojpuri, Tharu, Tamang, Nepal Bhasa, Bajjika, Avadhi, Doteli, Urdu, and many Tibeto-Burman languages remain important regionally. The same census found a large Hindu majority alongside Buddhist, Muslim, Kirat, Christian, and other communities, but religious practice often intersects with local lineage and cultural traditions rather than fitting neat categories. Kathmandu Valley’s Newar heritage is visible in pagoda and shikhara temples, brick-and-timber urban fabric, metalwork, woodcarving, paubha painting, and shared Hindu-Buddhist sacred spaces. Maithil traditions connect the southeastern plains with the wider Mithila region, while Tibetan Buddhist monasteries structure cultural life in parts of the high Himalaya. Modern literature, music, cinema, education, and labor migration increasingly connect regional traditions to national and transnational publics.
Transport is constrained by extreme relief and Nepal’s lack of direct access to the sea. The East-West Highway, about 1,027 kilometres long, forms the principal terrestrial spine across the Tarai, while north-south highways climb toward hill cities and border crossings; landslides, river erosion, and difficult maintenance make all-season reliability uneven in mountain districts. Rail remains marginal, limited chiefly to a short cross-border passenger line in Madhesh connected with India, so most domestic freight and passenger movement depends on roads and aviation. Tribhuvan International Airport in Kathmandu remains the main international gateway, supplemented by Gautam Buddha International Airport near Bhairahawa and Pokhara International Airport. External merchandise trade relies heavily on Indian road and rail corridors to seaports. Electricity infrastructure has changed faster: hydropower supplies the overwhelming majority of domestic generation, new plants continue to enter service, and cross-border transmission supports seasonal exports to India and a 40 MW supply arrangement with Bangladesh through the Indian grid. Digital connectivity is widespread, although terrain still contributes to rural service gaps.
Nepal’s regional importance follows from the geography that constrains it: it occupies the central Himalayan watershed between India and China, depends on external transit, and shares river systems, labor markets, energy links, and security interests with its neighbors. The open border with India underpins migration, commerce, and family networks, while China is an important source of goods, investment, and infrastructure diplomacy despite the Himalayan barrier. Nepal participates in the United Nations, SAARC, BIMSTEC, and other multilateral institutions, and its expanding hydropower trade gives it a growing role in South Asian electricity integration. Medium-term opportunities lie in reliable power exports, better logistics, higher-productivity agriculture and services, and converting remittance income into domestic investment. The counterweights are structural: difficult terrain, disaster exposure, climate stress, uneven state capacity, policy instability, weak job creation, and dependence on imports and overseas employment. Its future position will therefore depend less on geopolitical symbolism than on whether institutions and infrastructure can turn a constrained mountain geography into more productive regional connectivity.
