Sandwiched between two Asian giants--China and India--Nepal traditionally has been characterized as "a yam caught between two rocks." Noted for its majestic Himalayas, which in Sanskrit means the abode of snow, Nepal is very mountainous and hilly. Its shape is roughly rectangular, about 800 kilometers long and about 100 to 200 kilometers wide, and comprises a total of 147,181 square kilometers of land. It is slightly larger than Bangladesh or the state of Arkansas. Nepal is a landlocked country, surrounded by India on three sides and by China's Xizang Autonomous Region (Tibet) to the north. It is separated from Bangladesh by an approximately 15 kilometer wide strip of India's state of West Bengal, and from Bhutan by the 88 kilometer wide Sikkim, also an Indian state. Such a confined geographical position is hardly enviable. Nepal is almost totally dependent on India for transit facilities and access to the sea--that is, the Bay of Bengal--even for most of the goods coming from China.

The Land

For a small country, Nepal has great physical diversity, ranging from the Tarai Plain -- the northern rim of the Gangetic Plain situated at about 300 meters above sea level in the south -- to the 8850-meter-high Mount Everest, locally known as Sagarmatha (its Nepali name), in the north. From the lowland Tarai belt, landforms rise in successive hill and mountain ranges, including the stupendous rampart of the towering Himalayas, ultimately reaching the Tibetan Plateau beyond the Inner Himalayas. This rise in elevation is punctuated by valleys situated between mountain ranges. Within this maze of mountains, hills, ridges, and low valleys, elevational (altitudinal) changes resulted in ecological variations.

Nepal commonly is divided into three broad physiographic areas: the Mountain Region, the Hill Region, and the Tarai Region. All three parallel each other, from east to west, as continuous ecological belts, occasionally bisected by the country's river systems. These ecological regions were divided by the government into development sectors within the framework of regional development planning.

The rhythm of life in Nepal, as in most other parts of monsoonal Asia, is intricately yet intrinsically intertwined with its physical environment. As scholar Barry Bishop learned from his field research in the Karnali region in the northwest, the livelihood patterns of Nepal are inseparable from the environment.

The Mountain Region

The Mountain Region (called Parbat in Nepali) is situated at 4,000 meters or more above sea level to the north of the Hill Region. The Mountain Region constitutes the central portion of the Himalayan range originating in the Pamirs, a high altitude region of Central Asia. Its natural landscape includes Mount Everest and the other seven of the world's ten highest peaks, which are the legendary habitat of the mythical creature, the yeti, or abominable snowman. In general, the snow line occurs between 5,000 and 5,500 meters. The region is characterized by inclement climatic and rugged topographic conditions, and human habitation and economic activities are extremely limited and arduous. Indeed, the region is sparsely populated, and whatever farming activity exists is mostly confined to the low-lying valleys and the river basins, such as the upper Kali Gandaki Valley.

In the early 1990s, pastoralism and trading were common economic activities among mountain dwellers. Because of their heavy dependence on herding and trading, transhumance was widely practiced. While the herders moved their goths (temporary animal shelters) in accordance with the seasonal climatic rhythms, traders also migrated seasonally between highlands and lowlands, buying and selling goods and commodities in order to generate much needed income and to secure food supplies. =]

The Hill Region

Situated south of the Mountain Region, the Hill Region (called Pahar in Nepali) is mostly between 1,000 and 4,000 meters in altitude. It includes the Kathmandu Valley, the country's most fertile and urbanized area. Two major ranges of hills, commonly known as the Mahabharat Lekh and Siwalik Range (or Churia Range), occupy the region. In addition, there are several intermontane valleys. Despite its geographical isolation and limited economic potential, the region always has been the political and cultural center of Nepal, with decision-making power centralized in Kathmandu, the nation's capital. Because of immigration from Tibet and India, the hill ranges historically have been the most heavily populated area. Despite heavy out-migration, the Hill Region comprised the largest share of the total population in 1991.

Although the higher elevations (above 2,500 meters) in the region are sparsely populated because of physiographic and climatic difficulties, the lower hills and valleys are densely settled. The hill landscape is both a natural and cultural mosaic, shaped by geological forces and human activity. The hills, sculpted by human hands into a massive complex of terraces, are extensively cultivated.

Like the Mountain Region, the Hill Region was a food-deficit area in the early 1990s, although agriculture was the predominant economic activity supplemented by livestock raising, foraging, and seasonal migrating of laborers. The vast majority of the households living in the hills were land-hungry and owned largely pakho (hilly) land. The poor economic situation caused by lack of sufficient land was aggravated by the relatively short growing season, a phenomenon directly attributable to the climatic impact of the region's higher altitude. As a result, a hill farmer's ability to grow multiple crops was limited. The families were forced to adapt to the marginality, as well as the seasonality, of their environment, cultivating their land whenever they could and growing whatever would survive. Bishop has noted that "as crop productivity decreases with elevation, the importance of livestock in livelihood pursuits . . . increases. For many Bhotia [or Bhote] living in the highlands . . . animal husbandry supplants agriculture in importance." During the slack season, when the weather did not permit cropping, hill dwellers generally became seasonal migrants, who engaged in wage labor wherever they could find it to supplement their meager farm output. Dependence on nonagricultural activities was even more necessary in the mountain ecological belt.

The Tarai Region

In complete topographic contrast to the Mountain and Hill regions, the Tarai Region, also called Madhesh, is a lowland tropical and subtropical belt of flat, alluvial land stretching along the Nepal-India border, and parallel to the Hill Region. It is the northern extension of the Gangetic Plain in India, commencing at about 300 meters above sea level and rising to about 1,000 meters at the foot of the Siwalik Range. The Tarai includes several valleys (dun), such as the Surkhet and Dang valleys in western Nepal, and the Rapti Valley (Chitwan) in central Nepal.

The word tarai, a term presumed to be derived from Persian, means "damp," and it appropriately describes the region's humid and hot climate. The region was formed and is fed by three major rivers: the Koshi, the Narayani (India's Gandak River), and the Karnali. A region that in the past contained malaria-infested, thick forests, commonly known as char kose jhari (dense forests approximately 12 kilometers wide), the Tarai was used as a defensive frontier by Nepalese rulers during the period of the British Raj (1858-1947) in India. In 1991 the Tarai served as the country's granary and land resettlement frontier; it became the most coveted internal destination for land-hungry hill peasants.

In terms of both farm and forest lands, the Tarai is becoming Nepal's richest economic region. Overall, Tarai residents enjoy a greater availability of agricultural land than other Nepalese because of the area's generally flat terrain, which is drained and nourished by several rivers. Additionally, it has the largest commercially exploitable forests. In the early 1990s, however, the forests were being increasingly destroyed because of growing demands for timber and agricultural land.

Climate

Nepal has a great deal of variation in climate. Its latitude is about the same as that of Florida, and a tropical and subtropical climate exists in the Tarai Region. Outside the Tarai, however, the climate is completely different. The remarkable differences in climatic conditions are primarily related to the enormous range of altitude within such a short north-south distance. The presence of the east-west-trending Himalayan massifs to the north and the monsoonal alteration of wet and dry seasons also greatly contribute to local variations in climate. Scholar Sharad Singh Negi identifies five climatic zones in Nepal based on altitude: the tropical and subtropical zone of below 1,200 meters in altitude; the cool, temperate zone of 1,200 to 2,400 meters in altitude; the cold zone of 2,400 to 3,600 meters in altitude; the subarctic climatic zone of 3,600 to 4,400 meters in altitude; and the arctic zone above 4,400 meters in altitude. In terms of natural vegetational regimes or distribution patterns, altitude again plays a significant role. Below 1,200 meters, the dominant form of vegetation consists of tropical and subtropical rain forests.

Altitude also affects annual rainfall or precipitation patterns. Up to about 3,000 meters, annual rainfall totals increase as the altitude increases; thereafter, annual totals diminish with increasing altitude and latitude. In addition to this latitudinal differentiation in rainfall, two other patterns can be discerned. First, given the northwestward movement of the moisture-laden summer monsoon (June to September), the amount of annual rainfall generally decreases from east to west. However, there are certain pockets with heavy annual rainfall totals, for example, the Pokhara Valley in central Nepal. Second, the horizontal extension of hill and mountain ranges creates a moist condition on south- and east-facing slopes whereas it produces a major rain shadow on the northern sides of the slopes. The aridity increases with altitude and latitude, especially on the northern slopes, and reaches its climax in the inner Himalayan region and on the Tibetan Plateau. Eastern Nepal receives approximately 2,500 millimeters of rain annually, the Kathmandu area about 1,420 millimeters, and western Nepal about 1,000 millimeters.

The towering Himalayas play a critical role, blocking the northwesterly advances of moist, tropical air from the Bay of Bengal, and ultimately leading to its conversion to rain in the summer. In the winter, this range prevents the outbursts of cold air from Inner Asia from reaching southern Nepal and northern India, thus ensuring warmer winters in these regions than otherwise would be the case.

In addition, there are seasonal variations in the amount of rainfall, depending on the monsoon cycle. Bishop divides the monsoon cycle into four seasons: premonsoon, summer monsoon, postmonsoon, and winter monsoon. The premonsoon season generally occurs during April and May; it is characterized by the highest temperatures, reaching 40 °C during the day in the Tarai Region and other lowlands. The hills and mountains, however, remain cool.

The summer monsoon, a strong flow of moist air from the southwest, follows the premonsoon season. For the vast majority of southern Asians, including Nepalese, the term monsoon is synonymous with the summer rainy season, which makes or breaks the lives of hundreds of millions of farmers on the subcontinent. Even though the arrival of the summer monsoon can vary by as much as a month, in Nepal it generally arrives in early June, is preceded by violent lightning and thunderstorms, and lasts through September, when it begins to recede. The plains and lower Himalayas receive more than 70% of their annual precipitation during the summer monsoon. The amount of summer monsoon rain generally declines from southeast to northwest as the maritime wedge of air gradually becomes thinner and dryer. Although the success of farming is almost totally dependent on the timely arrival of the summer monsoon, it periodically causes such problems as landslides; subsequent losses of human lives, farmlands, and other properties (not to mention great difficulty in the movement of goods and people); and heavy flooding in the plains. Conversely, when prolonged breaks in the summer monsoon occur, severe drought and famine often result.

The postmonsoon season begins with a slow withdrawal of the monsoon. This retreat leads to an almost complete disappearance of moist air by mid-October, thus ushering in generally cool, clear, and dry weather, as well as the most relaxed and jovial period in Nepal. By this time, the harvest is completed and people are in a festive mood. The two biggest and most important Hindu festivals-- Dashain and Tihar (Dipawali)--arrive during this period, about one month apart. The postmonsoon season lasts until about December.

After the postmonsoon, comes the winter monsoon, a strong northeasterly flow, which is marked by occasional, short rainfalls in the lowlands and plains and snowfalls in the high-altitude areas. The amount of precipitation resulting from the northeast land trade winds varies considerably but increases markedly with elevation. The secondary winter precipitation in the form of snowfalls in the Himalayas is important for generating a sufficient volume of spring and summer meltwaters, which are critical for irrigation in the lower hills and valleys where agriculture predominates. Winter precipitation is also are indispensable for the success of winter crops, such as wheat, barley, and numerous vegetables.

River system

Nepal can be divided into three major river systems from east to west: the Koshi River basin, the Narayani River basin (India's Gandak River), and the Karnali River basin. All ultimately become major tributaries of the Ganges River in northern India. After plunging through deep gorges, these rivers deposit their heavy sediments and debris on the plains, thereby nurturing them and renewing their alluvial soil fertility. Once they reach the Tarai Region, they often overflow their banks onto wide floodplains during the summer monsoon season, periodically shifting their courses. Besides providing fertile alluvial soil, the backbone of the agrarian economy, these rivers present great possibilities for hydroelectric and irrigation development. To date Nepal has not made extensive use of its hydorlelectric resourses. All of them make use of the natural elevation differences, diverting water from the river and running it through turbines further downstream. The latest one is the Kali Gandaki hydroelectricity project a few km north of Tansen. Building dams in Nepal has remained a disputed issue, mainly because of the high risk of earthquakes in the region. None of the river systems support any significant commercial navigation facility. Rather, the deep gorges formed by the rivers represent immense obstacles to establishing the broad transport and communication networks needed to develop an integrated national economy. As a result, the economy in Nepal has remained fragmented. Because Nepal's rivers have not been harnessed for transportation, most settlements in the Hill and Mountain regions remain isolated from each other. As of 1991, trails remained the primary transportation routes in the hills. The eastern part of the country is drained by the Koshi River, which has seven tributaries. It is locally known as the Sapt Kosi, which means seven Kosi rivers (Tamur, Likhu Khola, Dudh, Sun, Indrawati, Tama, and Arun). The principal tributary is the Arun, which rises about 150 kilometers inside the Tibetan Plateau. The Narayani River drains the central part of Nepal and also has seven major tributaries (Daraudi, Seti, Madi, Kali, Marsyandi, Budhi, and Trisuli). The Kali Gandaki, which flows between the Dhaulagiri Himal and the Annapurna Himal (Himal is the Nepali variation of the Sanskrit word Himalaya), is the main river of this drainage system. The river system draining the western part of Nepal is the Karnali. Its three immediate tributaries are the Bheri, Seti, and Karnali rivers, the latter being the major one. The Maha Kali, which also is known as the Kali and which flows along the Nepal-India border on the west side, and the Rapti River also are considered tributaries of the Karnali.

Forests

25.4% of Nepal's land area, or about 36,360 km² (14,039 mi²) is covered with forest according to FAO figures from 2005. FAO estimates that around 9.6% of Nepal's forest cover consists of "primary forest" which is relatively intact. About 12.1% Nepal's forest is classified as "protected" while about 21.4% is "conserved" according to FAO. About 5.1% Nepal's forests are classified as "production forest." Between 2000-2005, Nepal lost about 2640 km² of forest. Nepal's 2000-2005 total deforestation rate was about 1.4% per year meaning it lost an average of 530 km² of forest annually. Nepal's total deforestation rate from 1990-2000 was 920 km² or 2.1% per year. The 2000-2005 true deforestation rate in Nepal, defined as the loss of primary forest, is -0.4% or 70 km² per year.
