The Innocent Victim of Climatic Changes!
12 years back in late July 2010, floods in Pakistan began
resulting from heavy monsoon rains in the Khyber Pakhtunkhwa, Sindh, Punjab,
and, Baluchistan regions of Pakistan, which affected the Indus River basin.
Approximately one-fifth of Pakistan's total land area was affected by floods,
with the Khyber Pakhtunkhwa province facing the brunt of the damage and
casualties (above 90% of all the deaths occurred in the province). Nationwide,
there were 1,985 deaths. According to Pakistani government data, the floods
directly affected about 20 million people, mostly by the destruction of
property, livelihood, and infrastructure.
Floods submerged 17 million acres (69,000 km2) of
Pakistan's most fertile cropland, killed 200,000 livestock, and washed away
massive amounts of grain. A major concern was that farmers would be unable to
meet the fall deadline for planting new seeds in 2010, which implied a loss of
food production in 2011, and potential long-term food shortages. The
agricultural damage reached more than 2.9 billion dollars and included over
700,000 acres (2,800 km2) of lost cotton crops, 200,000 acres (810
km2) of sugar cane, and 200,000 acres (810 km2) of rice,
in addition to the loss of over 500,000 tons of stocked wheat, 300,000 acres
(1,200 km2) of animal fodder and the stored grain losses.
And now again on 14th June 2022, floods in Pakistan have killed
1,486 people. The floods were caused by heavier than usual monsoon rains and
melting glaciers that followed a severe heat wave, all of which are linked to climate
change. It is the world's deadliest flood since the 2017 South Asian floods and
is described as the worst in the country's history. On 25 August, Pakistan
declared a state of emergency because of the flooding. By 29 August, Pakistan's
minister of climate change said around "one-third" of the country was
under water, affecting 33 million people. The government of Pakistan has
estimated a loss of US$30 billion so far from flooding across the country.
What is the reason behind the flood in Pakistan?
Climate change is the main factor caused by an increase in carbon
dioxide and other greenhouse gases in the earth's atmosphere mostly from fossil
fuel emissions. In Pakistan, environmental degradation and climate change are
adversely affecting the economy, livelihood of the poor, and sustainable
development.
In carbon dioxide and other fossil fuel emissions, Pakistan
contributed less than 1 percent but affecting by climate change the most.
Countries that are responsible for these climatic changes and
global warming are the following: (Emission in Million metric tons)
China — 9,877.
United States — 4,745.
India — 2,310.
Russia — 1,640.
Japan — 1,056.
Germany — 644.
South Korea — 586.
Iran — 583
Canada — 570
Saudi Arabia — 495
How to reduce and minimize the effect of climatic changes?
Put a price on carbon.
End fossil fuel subsidies.
Build low-carbon, resilient cities.
Increase energy efficiency and use of renewable energy.
Implement climate-smart agriculture and increase forest
landscapes.
Forestation is the easiest and cheapest way which can reduce the effect of climatic changes and global warming. It has also some health-related benefits.
Why do I need to plant?
If you're looking for a reason to avoid cutting down trees,
this summer's record-breaking heat waves may be the reason to stop cutting trees.
According to a recent study, trees can reduce summer day temperatures by up to
10 degrees Fahrenheit.
Heat reduction
Trees provide cool shade for houses, office
buildings, parks, and roads. They turn water into vapor while cooling the air
inside them. According to a recent study by the National Academy of Sciences,
to get the full temperature benefit, tree canopy cover must be greater than 40
percent for cooling. "A single city would need half the coverage of a
green network of branches and leaves," the experts wrote.
Reduction of air pollution
Trees absorb carbon which prevents the
increase of carbon in the atmosphere.
Reduced energy emissions
According to one study, trees reduce energy costs by $4 billion annually. "Having these trees shade your buildings will reduce your air conditioning costs. By removing these trees, your buildings will start to heat up, which will run more air conditioning and burn more fuel, causing pollution and Emissions to increase.
