Geographical Regions of Nepal – Terai is part of the great Ganesh Plain, accounts for just over 20% of Nepal’s land area. Terai is extending north from the southern border with India to the first foothills. Nevermore full than 35 km (22 miles), it is hot and humid most of the year.
Until recently it was covered by dense forests filled with wildlife, from rare butterflies to Bengal tigers. Last two or three decades these forests have been widely encroached on. The woods cut down, and the wildlife exterminated. A massive influx of settlers means that the Terai is where the majority of the Nepalis live nowadays.
Geography of The Terai
This human settlement has ravaged the Terai. Where British Hunter and explorer Jim Corbett in the 1930s stalked man-eating tigers and fished for huge fighting bream in the shade of ancient forests. There are now only eroded river valleys up to a mile wide and a patchwork of forest and cultivated areas.
For much of the year, river beds are dry. During the summer they are flooded from bank to bank with silted torrents changing course from year to year. Many houses stand on stilts. Like so many places on the planet, the Terai has become proof of the instantaneous and irreversible damage of population growth.
Geography of The Siwalik zone
The Siwalik zone, with the Churia range, rises from the Terai to 1,200 m (4,000 ft). Its steep slopes and dry climate have left it relatively uninhabited. To the north are broad valleys, such as Rapti Dun, which in places separate the Siwalik from the Mahabharat.
The Mahabharat forms a barrier between the plains and the fertile midlands. It too is sparsely populated, but covered with terraced slopes. Most of Nepal’s water passes through this region which until very recently had lush deciduous forests that have nearly all been cut for fuelwood. Somewhat off the beaten track, it has mountain passes as low as 210 m (700 ft) and peaks over 2,700 m (9,000 ft).

More than 40 per cent of the population occupies the temperate valleys of Kathmandu and Pokhara that dominate the Pagad Zone or Midlands. Here the soil is mostly alluvial and fertile; crops of nearly every kind can be grown at altitudes between 600 and 2,100 m (2,000 and 7,000 ft).
Higher in the Himalayas, human habitation is isolated in remote valleys or sheltered where possible on the elevated plateaus. Here people live much as they did a thousand years ago, some still rooted in the Stone Age. Most of the high country is above treeline for much of the year its rocky slopes covered by snow.
History Of Himalayas
Nepal has one of the world’s highest birthrates, with its population growing so fast. The country may soon find itself hard-pressed for food. Over-cultivation of the steep valley slopes above the river gorges has already turned the landscape into a textbook case of deforestation and soil erosion.
With its steep farmlands unprotected by the deep root systems and sheltering foliage of perennial vegetation. The fierce monsoon rains wash away the fragile topsoil. It can bring thousands of tons of mountainside land sliding down the slopes. Yet the beauty of Nepal’s landscape remains virtually indestructible. The sheer scale and form, even of the eroded walls of the valleys, are still magnificent enough to take the breath away.

It is these same mountain walls that have kept Nepal remote from the world until this century.
