Climatic changes are actually
happening and Earth is heating up, the glaciers melting and water is being
consumed by the growing population. With the scarcity of water, there is less
food to grow and South Asia is the most vulnerable region of the world as its
population is growing far too quickly and the glaciers in the Himalayas
depleting very fast. For Pakistan, the bad news is that the River Indus is 30 to
40 per cent dependent on the Himalayan glaciers.
It's not only the Pakistan that has experienced record-breaking extreme weather
events recently, in the last couple months extreme weather has struck around the
world with startling ferocity. In addition to this the monsoon downpours were
some of the heaviest seen in recent years. Flooding in Indonesia, Drought in
South and north Korea, land sliding due to heavy rain in Bangladesh, Shifts in
glacial melt and rain fall are threatening crops ,water scarcity in Pakistan are
matters of great concern.
Monsoon pattern have mainly disturb severely by these global changing, It should
not be called a ‘monsoon season’ as the precipitation has been 50% below normal
all over Pakistan. Normally as much as 80 percent of South Asia ‘s rain falls
during the June-to-September monsoon. But till end of July dry weather have
observing all over the Pakistan. This shortage of rain further causing negative
impact on food commodities as food items short fall resultant inflation.
The monsoon is brought by large-scale wind patterns that transport heat between
the northern and southern hemispheres. The reduction in seasonal rainfall in
South Asia over the past 50 years may be a result of tiny chemicals emitted into
the atmosphere by burning fossil fuels, according to U.S. scientists. In monsoon
season seasonal winds fluctuate widely and scientists have been developing new
models that may help farmers prepare for water-supply disruptions and mitigate
loss of life and property. Record monsoons last year caused floods in Pakistan
that displaced almost 20 million people and caused more than $9 billion in
According to the WFP, nearly half of Pakistan’s (180 million) people are at risk
of going short of food due to a recent surge in world food prices. In India, New
Delhi, already battling to contain double-digit food inflation, now faces
further price increases due to food shortages for its 1.2 billion people, some
42 percent of whom live in poverty. this further a key chain reaction in the
form of disease induction.
Giving poor people proper access to safe water and sanitation would save 2.5
million people a year from dying from diarrhea and other diseases spread by a
lack of hygiene, according to charity water Aid.
India has been drying out for half a century, and air pollution thousands of
kilo meters away is partly to blame. The Thar "Golden" Desert receives the
lowest rainfall in the country and has largely saline groundwater at levels 100m
below the surface.
Recent flood in India ,Bangladesh and Japan threatens the rice crop, many
countries 's soya crop is also effected by rain shortage. Salinity affects some
60 percent of ’s coastal farming lands, the United Nations estimates. In recent
decades, rising sea levels in the have encroached on vast tracts of low-lying
arable lands, making them too salty for some rice varieties to grow and
diminishing crop yields.
On the other side severe flooding across North Korea has killed 88 people and
left tens of thousands homeless, state media reported late on Saturday,
threatening to make the poverty-stricken country's already chronic food shortage
