The region is responsible for providing water to a large part of the Indian subcontinent and contains various flora and fauna. The Himalayas have a profound effect on the climate of the Indian subcontinent and the Tibetan Plateau. They prevent frigid, dry winds from blowing south into the subcontinent, which keeps South Asia much warmer than corresponding temperate regions in the other continents. Some of the highest mountains on earth are found in the region. Many rivers considered holy, like the Ganga and Yamuna flow from the Himalayas.
Rainfed agriculture continues to be the primary source of occupation and livelihood. There has been a shift towards market agriculture - pulses and vegetables are the major cash crops. Forest also forms an integral part of agricultural and animal husbandry practices. With the onset of the railways in the late 19th century in Western Himalayan states, large-scale destruction of forests began. After several rebellious movements in the early part of the 20th century, the government provided concessions for usufructs, such as fodder and fuelwood collection. At the same time, it allocated parts of forest land adjacent to villages under community arrangement.
