# Geography of Afghanistan

Afghanistan is a landlocked mountainous country located on the Iranian Plateau, at the crossroads of Central Asia and South Asia. The country is the 40th largest in the world in size. Kabul is the capital and largest city of Afghanistan, located in the Kabul Province. With a location at the intersection of major trade routes, Afghanistan has attracted a succession of invaders since the sixth century BCE.
Afghanistan contains most of the Hindu Kush. There are a number of major rivers in the country, including Amu Darya, Arghandab, Farah, Hari, Helmand, Kabul, Kokcha, and Kunar. The country also possesses many smaller rivers as well as streams, canals, lakes, ponds, and springs. Most of its fresh water historically flowed into neighboring countries.

## Regional classification

Afghanistan is sometimes classified as part of northwestern South Asia, though this remains a subject of debate and controversy due to its historical, geographical, ethnic, and cultural ties to Central Asia and the Middle East, in addition to its connections to South Asia. Many in Afghanistan consider their country to be an amalgamation of South Asian, Central Asian, and Middle Eastern cultures, and view their strict classification as solely South Asian as a denial of their Central Asian and Middle Eastern heritage. Moreover, such rigid classifications are often perceived as sources of ethnic tensions between communities.
Afghanistan has many historical connections to Central Asia and the Middle East. It was part of multiple Central Asian and Middle Eastern cultural and imperial spheres, such as the Persian Empire, Arab Caliphates, Durrani Empire, and various Turko-Persian Dynasties. It is also a Muslim-majority state, similar to the nations of Central Asia and the Middle East (with the exception of Israel). It is part of the Greater Middle East—a geopolitical term introduced during the George W. Bush administration—encompassing not only the core Middle Eastern states but also regions with historical, cultural, geopolitical, and geographical links to the Middle East, such as Morocco, Libya, Algeria, Pakistan, and Afghanistan. Additionally, it belongs to the socio-cultural sphere of Greater Iran as well as Greater Central Asia, further underscoring its historical and civilizational connections to Persianate traditions of Central Asia and the Middle East. Recognizing these historical and cultural connections, UNESCO in 1978 defined Central Asia to include both Afghanistan and Pakistan.
Further to the effect of Afghanistan having connections to Central Asia and the Middle East is its membership in organizations that represent these regions. For example, it is a member of Central Asia Regional Economic Cooperation (CAREC) Program, and the Economic Cooperation Organization (ECO), which includes Iran, Turkey, Afghanistan, Pakistan, and the Central Asian republics.
Recently, the classification of Afghanistan within South Asia has come under additional scrutiny due to the rise of Hindu nationalist movements in India that promote the idea of Akhand Bharat—a vision advocating for the annexation of Pakistan, Afghanistan, and other neighboring regions into India. Afghans argue that an exclusive classification of their countries as South Asian could be misinterpreted as an implicit validation of such expansionist ideologies, threatening the national and cultural identity of their homeland. As a result, they contend thatAfghanistan's connections to Central Asia and the Middle East must be acknowledged and emphasized to counter any expansionist narratives that challenge the country's sovereignty.

## Mountain systems

The Hindu Kush mountain range reaches a height of 7,492 m (24,580 ft) at Noshaq, Afghanistan's highest peak. Of the ranges extending southwestward from the Hindu Kush, the Foladi peak (Shah Foladi) of the Baba mountain range (Koh-i-Baba) reaches the greatest height: 5,142 m (16,870 ft). The Safed Koh range, which includes the Tora Bora area, dominates the border area southeast of Kabul.
Important passes include the Unai Pass across the Safed Koh, the Kushan and Salang Passes through the Hindu Kush, and the Khyber Pass that connects Afghanistan with Pakistan. The summit of the Khyber Pass at 1,070 m (3,510 ft) at Landi Kotal, Pakistan is 5 km (3 mi) east of the border town of Torkham. Other key passages through the mountainous Pakistan border include two from Paktika Province into Pakistan's Waziristan region: one at Angoor Ada, and one further south at the Gumal River crossing, plus the Charkai River passage south of Khost, Afghanistan, at Pakistan's Ghulam Khan village into North Waziristan. The busy Pak-Afghan border crossing at Wesh, Afghanistan is in a flat and dry area, though this route involves Pakistan's Khojak Pass at 2,707 m (8,881 ft) just 14 km (9 mi) from the border. The border connects Kandahar and Spin Boldak in Afghanistan with Quetta in Pakistan.
The Wakhan Corridor in the northeast lies eastward of the province of Panjshir, between the Hindu Kush and the Pamir Mountains, which leads to the Wakhjir Pass into Xinjiang in China. In Kabul, and over all the northern part of the country to the descent at Gandamak, winter is rigorous, especially so on the high Arachosian plateau.
Although Herat is approximately 240 m (787 ft) lower than Kandahar, the summer climate there is more temperate along with the yearly climate. From May to September, the wind blows from the northwest with great force, and this extends across the country to Kandahar. The winter is mild; snow melts as it falls, and even on the mountains does not lie long. Three years out of four at Herat it does not freeze hard enough for the people to store ice. Yet, it was not very far from Herat, in Rafir Kala, in 1750, where Ahmad Shah's army, retreating from Persia, is said to have lost 18,000 men from cold in a single night. In the northern Herat districts records of the coldest month (February) show the mean minimum as −8 °C (18 °F) and the maximum as 3 °C (37 °F). The eastern reaches of the Hari River, including the rapids, are frozen hard in the winter, and people travel on it as on a road.

## Climate

Rainfall in Afghanistan is very scarce, and mainly only affects the northern highlands, arriving in March and April. Rainfall in the more arid lowlands is rare, and can be very unpredictable. Marked characteristics are the great differences of summer and winter temperature and of day and night temperature, as well as the extent to which change of climate can be attained by slight change of place. The Afghan climate is a dry one. The sun shines for three-fourths of the year, and the nights are clearer than the days.
Taking the highlands of the country as a whole, there is no great difference between the mean temperature of Afghanistan and that of the lower Himalaya. However, a remarkable feature of the Afghan climate is its extreme temperature range within limited periods. The smallest daily range in the north is when the weather is cold; the greatest is when it is hot. For seven months of the year (from May to November) this range exceeds 17 °C (31 °F) daily. Waves of intense cold occur, lasting for several days, and one may have to endure temperatures of −24 °C (−11 °F), rising to a maximum of −8 °C (18 °F). At Ghazni the snow has been known to stay long beyond the vernal equinox; the temperatures sink as low as −25 °C (−13 °F). Oral tradition tells of the destruction of the entire population of Ghazni by snowstorms on more than one occasion. On the other hand, the summer temperature is exceedingly high, especially in the Oxus regions, where a shade maximum of 45–50 °C (113–122 °F) is not uncommon.
The summer heat is strong in the Sistan Basin, Jalalabad and Turkestan. The simoom wind occurs in Kandahar province during the summer. The hot season is rendered more intense by frequent dust storms and strong winds; whilst the bare rocky ridges that traverse the country, absorbing heat by day and radiating it by night, render the summer nights most oppressive. In Kabul the heat is tempered occasionally by cool breezes from the Hindu Kush, and the nights are usually cool. In Kandahar snow seldom falls on the plains or lower hills; when it does, it melts at once.
The combination of hot summers and bitterly cold winters has been noted comparable to the U.S. state of Wyoming.
The summer rains that accompany the southwest monsoon in India, beat along the southern slopes of the Himalaya, and travel up the Kabul valley as far as Laghman, though they are more clearly felt in Bajour and Panjkora, under the Hindu Kush, and in the eastern branches of Safed Koh. Rain also falls at this season at the head of Kurram valley. South of this the Suliman mountains may be taken as the western limit of the monsoon's action. It is not felt in the rest of Afghanistan, in which, as in the rest of western Asia, the winter rains and snow are the most considerable. The spring rain, though less copious, is more important to agriculture than the winter rain, unless where the latter falls in the form of snow. In the absence of monsoon influences there are steadier weather indications than in India. The north-west blizzards which occur in winter and spring are the most noticeable feature, and their influence is clearly felt on the Indian frontier.

## Rivers, streams and lakes

Afghanistan receives snow between November and March, which gradually melts into numerous rivers, streams, canals, lakes, ponds, and springs, but most of the country's fresh water continues to flow into neighboring countries. It loses about two-thirds of its water to neighboring Pakistan, Iran, Tajikistan, Uzbekistan and Turkmenistan.
The nation's drainage system is largely landlocked.

## Vegetation

The characteristic distribution of vegetation on the mountains of Afghanistan is worthy of attention. The great mass of it is confined to the main ranges and their immediate offshoots, whilst on the more distant and terminal prolongations it is almost entirely absent; in fact, these are naked rock and stone. On the Safed Koh alpine range itself and its immediate branches, at a height of 1,800–3,000 m (5,900–9,800 ft) there is abundant growth of large forest trees, among which conifers are the most noble and prominent, such as Cedrus deodara, Abies excelsa, Pinus longifolia, Pinus pinaster, Stone pine (the edible pine, although this species is probably introduced, since it is original to Spain and Portugal) and the larch. There is also the yew, the hazel, juniper, walnut, wild peach and almond. Growing under the shade of these are several varieties of rose, honeysuckle, currant, gooseberry, hawthorn, rhododendron and a luxuriant herbage, among which the ranunculus family is important for frequency and number of genera. The lemon and wild vine are also here met with, but are more common on the northern mountains. The walnut and oak (evergreen, holly-leaved and kermes) descend to the secondary heights, where they become mixed with alder, ash, khinjak, Arbor-vitae, juniper, with species of Astragalus. Here also are Indigoferae rind dwarf laburnum.
In Afghanistan forest cover is around 2% of the total land area, equivalent to 1,208,440 hectares (ha) of forest in 2020, which was unchanged from 1990. In 2020, naturally regenerating forest covered 1,208,440 hectares (ha). Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 0% of the forest area was found within protected areas. For the year 2015, 100% of the forest area was reported to be under public ownership.
Down to 1,000 m (3,300 ft) there are wild olive, species of rock-rose, wild privet, acacias and mimosas, barberry and Zizyphus; and in the eastern ramifications of the chain, Nannerops ritchiana (which is applied to a variety of useful purposes), Bignonia or trumpet flower, sissu, Salvadora persica, verbena, acanthus, varieties of Gesnerae.
The lowest terminal ridges, especially towards the west, are, as it has been said, naked in aspect. Their scanty vegetation is almost wholly herbal; shrubs are only occasional; trees almost non-existent. Labiate, composite and umbelliferous plants are most common. Ferns and mosses are almost confined to the higher ranges.
In the low brushwood scattered over portions of the dreary plains of the Kandahar tablelands, it is possible to find leguminous thorny plants of the papilionaceous suborder, such as camel-thorn (Hedysarum alhagi), Astragalus in several varieties, spiny rest-harrow (Ononis spinosa), the fibrous roots of which often serve as a tooth-brush; plants of the sub-order Mimosae, as the sensitive mimosa; a plant of the rue family, called by the natives lipad; the common wormwood; also certain orchids, and several species of Salsola. The rue and wormwood are in general use as domestic medicines—the former for rheumatism and neuralgia; the latter in fever, debility and dyspepsia, as well as for a vermifuge. The lipad, owing to its heavy nauseous odour, is believed to keep off evil spirits. In some places, occupying the sides and hollows of ravines, it is found the Rose Bay, called in Persian khar-zarah, or ass-bane, the wild laburnum and various Indigoferae.
In the last several decades, 90% of forests in Afghanistan have been destroyed and much of the timber has been exported to neighboring Pakistan. As a result, large percent of Afghanistan's land could be subject to soil erosion and desertification. On the positive note, the Karzai administration and international organizations are helping counter this problem by often planting millions of saplings. Afghanistan had a 2018 Forest Landscape Integrity Index mean score of 8.85/10, ranking it 15th globally out of 172 countries.
