Think why disasters like Uttarakhand happened ?

Explanation

1. Uttarakhand and Himachal Pradesh are two hill states that were stuck by extreme rains in 2013.
2. Heavy rainfall has wrecked havoc on the region because of fragile nature of Himalayan range and poor soil stability in its deep steps. But it is the man made factor that has compounded the scale of the disaster.
3. Unabated expansion of hydro power project and construction of roads to accommodate ever-increasing tourism especially religious tourism are also major causes for the unprecendented scale of devastation.
4. The valleys of Yamuna, Ganga and Alakananda attract heavy traffic of tourists. For them, government has to construct new roads and widen the existing ones.
5. A new mountain range like Himalayas will remain study if not tampered much. But the huge expansion of trade and transport is bringing the mountains in Uttarakhand down.
6. Study should be conducted to assess the carrying capacity of the Himalayas and development should be planned accordingly.
Threat from dams : The Ganga in upper reaches has been engineers' play ground. The central electrical authority and Uttarakhand power department have estimated the rivers hydrolytic pottential at some 9000 muc and planned 70 odd projects on its tributaries. In building these, key tributaries have been modified through diversions through tunnels or reservoirs.
