The Sub-Himalayan Region.

            It covers T. Hagen’s Midland and inner Himalayan  . It lies between the Mhabharat in the south and the Himalayas in the north. This broad  belt also spreads continuously all through the length of the country. The climate  and the soil of this belt is quite suitable to the human settlement. The people have been living in this  belt since antiquity . that’s why, there is  a thick population in this belt. Thick population causes extensive agricultural  practices,  which in turn, devastate forests.

this is a traditional zone of Nepalese settlement. So , this region has more agricultural and les forest land, especially in the east.May be due to the influence of Darjeeling, Kurseong and Kalimpong of India, the capital of Nepal in nearer to the  east and  the industrial centre of the country is also located in the east , the population is also excessively thick in the east, considering the acreage of country. There should be about two third of the total population in the west, but nearly half of the total population if found in the east including Kathmandu valley, ,though  it covers only about one third of the total area. The soil of this region covers more than half of the soil found in the international soil classification chart .the main deposited soils are soil, loam, sandy loam,  clay , sandy clay, sandy clay loam, loamy sand ,glay , glayees sand and sand. Among the soils found in this region there is peculiar type of silt found in the  valleys, especially in the Kthamandu valley. It is a kind of black soil, a sort of completely decomposed  humus , a pure loam, which is quite fertile and quite lustrous too. The people of the Kathmandu valley use it for plastering  their house walls  as well. And there is another kind of black soil which seems like coal and the local name is “Matti Koila” meaning clay-coat. It is not coal . the people of Kathmandu valley use this soil in kitchens and also in brick factories to bake the bricks. This soil geves very gook calorie of heat with the combination of the paddy husks and the mustard cake made from seeds after the oil has been pressed out. this  Matti Koila is nothing a half  decomposed pith or humus. It gives a good service when there is no supply of coal from outside . compared to the rocks of China , Russia, Alps. Etc, the rocks of this region are quite young as is evident from the fresh boulders and pebbles found in the fringes of the rivers . the main rocks found here are quartz, quartzite , granite, gneiss, micaschist, slates, phyllite, limestone , talc stones , soapstone , rock-salt and sandstone. In this belt there are less forest lands and more agricultural lands , except in far-west, especially in Jumla and Humla districts , where some virgin forests are still found.
