Q3. Read the passage given below and answer the questions that follow:
Necessity is indeed the mother of invention. When areas in and around Leh began to
experience water shortages, life didn't grind to a halt. Why? Because Chewang
Norphel, a retired civil engineer in the Jammu and Kashmir government came up with
the idea of artificial glaciers. Ladakh, a cold desert at an altitude of 3,000-3,500 metres
above sea level, has a low average annual rainfall rate of 50mm. Glaciers have always
been the only source of water.
Agriculture is completely dependent on glacier melt unlike the rest of river/monsoon-
fed India. But over the years with increasing effects of climate change, rainfall and
snowfall pattems have been changing, resulting in severe shortage and drought
situations. Given the severe winter conditions, the window for farming is usually limited
to one harvest season.
It is located between the natural glacier above and the village below. The one closer
to the village and lowest in altitude melts first, providing water during April/May, the
crucial sowing season. Further layers of ice above melt with increasing temperature
thus ensuring continuous supply to the fields. Thus, farmers have been able to
manage two crops instead of one. It costs about Rs.1,50,000 and above to create
one.Fondly called the "glacier man", Mr. Norphel has designed over 15 artificial
glaciers in and around Leh since 1987. In recognition of his pioneering effort, he was
conferred the Padma Shri by President Pranab Mukherjee, in 2015. There are few
basic steps followed in creating the artificial glacier.
River or stream water at higher altitude is diverted to a shaded area of the hill, facing
north, where the winter sun is blocked by a ridge or a mountain range. At the start of
winter/November, the diverted water is made to flow onto sloping hill face through
distribution channels. Stone embankments are built at regular intervals which impede
the flow of water, making shallow pools and freeze, forming a cascade of Ice along the
slope. Ice formation continues for 3-4 months resulting in a large accumulation of ice
which is referred to as an "artificial glacier".
Questions :
1. Why have Glaciers been the only source of water for Ladakh?
Why has the pattern of snowfall and rainfall changed?
3. How are Glaciers significant for Irrigation?
