SEMESTER: 2
Like most of other south Asian countries, traditionally, Pakistan’s economy has been centered
on agriculture. However, in the recent past, manufacturing and services have also emerged as
major contributing sectors. The share of manufacturing sector is 30%. With the increasing
industrial & agricultural activities, energy demands, urbanization, traffic density and population
growth, the degradation of all segments (air, water & land) of environment is alarmingly
increasing and remains a grave concern. The unsound management of chemicals, especially in
the manufacturing and agricultural sectors, have further compounded the environmental issues.
20% of the registered industries in Pakistan are considered highly polluting. Under the Self-
monitoring and reporting program for industry in Pakistan, in category A (most hazardous) there
are 23 & 11 industrial sectors for industrial effluents and gaseous emission, respectively. Major
industries/clusters are in textiles, leather, steel, oil refineries & mills, chemicals, ceramics,
pharmaceuticals and food. Most of these are located in Sialkot, Faisalabad, Multan, Hyderabad,
Lahore, Peshawar and Rawalpindi cities. More than 10 industrial states are functional and a few
new ones are in development.
The effect that humanity is having on the environment is becoming ever-more important.
Through our actions we are destroying habitats and endangering the lives of future generations.
At this point there is no denying the fact that our environment is changing. Hundreds of studies
have been conducted to demonstrate that this is happening and it is having an effect on life
around us. However, many may be unaware of the specific issues that have led to these changes.
Terms like “climate change” and “genetic modification” are commonplace, but without
additional information it is difficult to see why they actually matter. To complicate the matter,
many of these issues are linked to one another. The key is that they are all important challenges
that need to be confronted.
Here we examine the biggest environmental problems facing our planet today and why they
should matter.
ENVIRONMENTAL ISSUES
Industrial waste water discharge from industries in the country has been estimated at 6.25 (in
2010) to a projected value of 12.50 million cubic meters per annum (in 2025). A combined
pollution load in waste water discharged to inland water bodies has been estimated at 28.6 (in
2010) to a projected value of 58.6 million tons/annum. Degradation of water quality, both for
human consumption and irrigation, due to industrial waste water discharge with high pollution
load and its resulting impacts on public health and environment are most obvious. In a recent
survey of 38 polluted sites in the country, it was shocking to observe, waste water from the
industrial estates and industrial units being discharged into agriculture fields mostly for cash
crops but also in a few, for food crops and vegetables, both on large and small scales. Water and
soil are known and well established pathways for toxic chemicals (metals, non-metals &
organics) getting into food chain and ultimately into human bodies, besides, to a lesser extent
through air. There are 37 industries identified and assessed in Punjab, Khyber Pakhtunkhawa and
Sindh. Two polluted sites were identified and assessed in and around Islamabad. Nine priority
polluted sites for which immediate remediation actions are required. Industrial chemicals
manufacturing and use, obsolete pesticides stocks and hospital wastes are main potential sources
of hazardous wastes in the country.

POLLUTION
Pollution is the process of making land, water, air or other parts of the environment dirty and not
safe or suitable to use. This can be done through the introduction of a contaminant into a natural
environment, but the contaminant doesn't need to be tangible. Things as simple as light, sound
and temperature can be considered pollutants when introduced artificially into an environment.
Toxic pollution affects more than 200 million people worldwide, according to Pure Earth, a non-
profit environmental organization. In some of the world's worst polluted places, babies are born
with birth defects, children have lost 30 to 40 IQ points, and life expectancy may be as low as 45
years because of cancers and other diseases. Read on to find out more about specific types of
pollution.
Land pollution is degradation or destruction of the Earth’s surface and soil, directly or indirectly,
as a result of human activities.
Land pollution may in turn slowly destroy our natural environment, which is already at risk.
Waste generated from polymers is a major contributor to land pollution. Polymer waste is
generally dumped in open spaces and become a breathing space for mosquitoes and flies. This
results in unhealthy environment and epidemic diseases. It is therefore, necessary to manage or
recycle these wastes. An efficient practice may be to incorporate polymer waste in mortar. This
paper investigates the possibility of using different polymers in cement mortar to produce
thermal resistant mortar. Polymers selected for study are scrap polyvinyl chloride pipes (PVC
pipes) and raw material of polyethylene terephthalate bottles (PET bottles). Scrap rubber tire
waste is also not recyclable or reusable and only 5% of tire waste is recycled rest is dumped into
open grounds, which again is hazardous to environment. In this study performance of mortar
incorporating 10%, 20% and 30% polymers as volume replacement of fine aggregate was
investigated. Results showed that incorporating polymer waste in mortar increases thermal
resistance of mortar, compressive strength on the other hand is deteriorated. Based upon findings
of the experiments performed it can be concluded that polymers can be used in mortar to increase
Land can become polluted by household garbage and by industrial waste. Organic material was
the largest component of the garbage generated. Paper and paperboard accounted for more than
26%; food was 15% and yard trimmings were 13%. Plastics comprised about 13% of the solid
waste, while rubber, leather and textiles made up 9.5% and metals 9%. Wood contributed to
6.2% of the garbage; glass was 4.4% and other miscellaneous materials made up about 3%.
Commercial or industrial waste is a significant portion of solid waste.
WATER POLLUTION
Water pollution is one of the major threats to public health in Pakistan. Drinking water quality is
poorly managed and monitored. Pakistan ranks at number 80 among 122 nations regarding
drinking water quality. Drinking water sources, both surface and groundwater are contaminated
with coliforms, toxic metals and pesticides throughout the country. Various drinking water
quality parameters set by WHO are frequently violated. Human activities like improper disposal
of municipal and industrial effluents and indiscriminate applications of agrochemicals in
agriculture are the main factors contributing to the deterioration of water quality. Microbial
and chemical pollutants are the main factors responsible exclusively or in combination for
various public health problems. This review discusses a detailed layout of drinking water quality
in Pakistan with special emphasis on major pollutants, sources of pollution and the consequent
health problems. The data presented in this review are extracted from various studies published
in national and international journals. Also reports released by the government and non-
governmental organizations are included.
Water pollution happens when chemicals or dangerous foreign substances are introduced to
water, including chemicals, sewage, pesticides and fertilizers from agricultural runoff, or metals
like lead or mercury. According to the Environmental Protection Agency (EPA), 44% of
assessed stream miles, 64% of lakes and 30% of bay and estuarine areas are not clean enough for
fishing and swimming. The EPA also states that the most common contaminants are bacteria,
mercury, phosphorus and nitrogen. These come from the most common sources of contaminates,
that include agricultural runoff, air deposition, water diversions and channelization of streams.
According to United Nations, 783 million people do not have access to clean water and around
2.5 billion do not have access to adequate sanitation. Adequate sanitation helps to keep sewage
and other contaminants from entering the water supply.
Warming water can also be harmful. The artificial warming of water is called thermal pollution.
It can happen when a factory or power plant that is using water to cool its operations ends up
discharging hot water. This makes the water hold less oxygen, which can kill fish and wildlife.
The sudden change of temperature in the body of water can also kill fish. According to
the University of Georgia, it is estimated that around half of the water withdrawn from water
systems in the United States each year is used for cooling electric power plants. .
Nutrient pollution, also called eutrophication, is another type of water pollution. It is when
nutrients, such as nitrogen, are added into bodies of water. The nutrient works like fertilizer and
makes algae grow at excessive rates. The algae blocks light from other plants. The plants die and
their decomposition leads to less oxygen in the water. Less oxygen in the water kills aquatic
animals.
AIR POLLUTION
Air pollution occurs when harmful or excessive quantities of substances are introduced into
Earth's atmosphere. Sources of air pollution include gases, particulates, and biological molecules.
Causes and Effects of Air pollution
Nowadays air over major cities throughout the world has become over burdened with gases
produced by automobiles. The death rate due to automobiles pollution is increasing rapidly in the
metropolitan areas. With passage of time people realized that polluted air had serious effects on
their health, climate and economics. Weather and climate have the integrated impact on human
activities which are resulting in worldwide concentration of the particulate of environmental
pollution viz.
chloroflorocarbons (CFCs), carbon dioxide, methane, nitrogen oxide, lead and several other dust
and gaseous particles.The rapid growth in motor vehicle activity in Pakistan and other rapidly
industrializing
low-income countries is contributing to high levels of urban air pollution, among other adverse
socioeconomic, environmental, health, and welfare impacts. This paper first discusses the local,
regional, and global impacts associated with air pollutant emissions resulting from motor vehicle
activity, and the technological, behavioral, and institutional factors that have contributed to these
emissions, in Pakistan.
The paper then discusses some implementation issues related to various policy measures that
have been undertaken, and the challenges of the policy context. Finally, the paper presents
insights and lessons based on the recent Pakistan experience, for better understanding and more
effectively addressing the transport air pollution problem in Pakistan and similar countries, in a
way that is sensitive to their needs,
capabilities, and constraints.
NOISE POLLUTION
Noise pollution, also known as environmental noise or sound pollution, is the propagation of
noise with ranging impacts on the activity of human or animal life, most of them harmful to a
degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and
propagation systems.
Karachi is facing an enormous problem of exceedingly high levels of traffic noise, which is
significantly higher than all the available international data. Vast number of people is at risk of
developing noise induced hear- ing loss, Psychological, Cardiovascular or other sys- temic
disorders in due course of time.
Even though humans can't see or smell noise pollution, it still affects the environment. Noise
pollution happens when the sound coming from planes, industry or other sources reaches harmful
levels. Research has shown that there are direct links between noise and health, including stress-
related illnesses, high blood pressure, speech interference, hearing loss. For example, a study
bythe WHO Noise Environmental Burden on Disease working group found that noise pollution
may contribute to hundreds of thousands of deaths per year by increasing the rates of coronary
heart disease. Under the Clean Air Act, the EPA can regulate machine and plane noise.
Underwater noise pollution coming from ships has been shown to upset whales' navigation
systems and kill other species that depend on the natural underwater world. Noise also makes
wild species communicate louder, which can shorten their lifespan.
LIGHT POLLUTION
Most people can't imagine living without the modern convenience of electric lights. For the
natural world, though, lights have changed the way that days and nights work. Some
consequences of light pollution are:
Scientists have determined that long artificial days can affect migration schedules, as they allow
for longer feeding times.
Streetlights can confuse newly hatched sea turtles that rely on starlight reflecting off the waves to
guide them from the beach to the ocean. They often head in the wrong direction.
Light pollution, called sky glow, also makes it difficult for astronomers, both professional and
amateur, to properly see the stars.
Plant's flowering and developmental patterns can be entirely disrupted by artificial light. Light
pollution could also be making smog worse by destroying nitrate radicals that helps the
dispersion of smog. Turning on so many lights may not be necessary.
DEFORESTATION
Causes
Mining
The increase of mining on tropical forests is furthering damage due to the rising demand and
high mineral prices.
Paper
America, China, Japan, and Canada make up more than of the world’s paper production—400
million tons a year. Approximately 640 million trees represent the paper that’s thrown away each
year, according to the Environment Paper Network.
Overpopulation
Forests are essentially the lungs of our planet .Tropical rainforests are extremely humid due to
the water vapor released along with the oxygen. But when a forest is cut down, the humidity
levels decrease and causes the remaining plants to dry out.
Effects
Further effects of deforestation include soil erosion and coastal flooding. Trees help the land to
retain water and topsoil, which provides the rich nutrients to sustain additional forest
life.Without forests, the soil erodes and washes away, causing farmers to move on and perpetuate
the cycle.
Trees help to mitigate carbon dioxide and other greenhouse gas emissions, but they become
carbon sources once they’re cut, burned, or otherwise removed. It’s estimated that deforestation
is responsible for around 20% of greenhouse gas emissions and 1.5 billion tons of carbon is
released every year by tropical deforestation.
Loss of Species.
Orangutans, giant pandas, rhinos, and the Asian elephant are just a few of hundreds of
endangered species due to deforestation.
Loss of Habitat
One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant
species due to their loss of habitat. 70% of land animals and plant species live in forests. Not
only does deforestation threaten species known to us, but also those unknown
Case study
This case study describes the deforestation that took place in Pakistan due to foreign invaders
and urbanization. In
the early 1200s, banana cultivation began to take off. The farmers cleared the forests to open
space for grain fields and banana groves. This reduced the trees in the area, but the crops that
grew allowed for an increase in the population. Pakistan moved ahead of the rest of Pakistan in
the early 1900s. At this time Pakistan started their industrial revolution while the rest of Pakistan
expanded on merchant capital. This industrial revolution caused the need for flat land for mining.
As the gold and diamond mines went up, so did profits and deforestation. Drastic deforestation
took place during the 1930s. The observers scared the locals by claiming that desertification and
permanent degradation of the soil was taking place. The locals panicked and started a
conservation movement. The colonial governments attempted to ban the burning of trees and
dried piles of brush in order to stop the deforestation. In the 1950s, the natives showed the
government that the burning was not harming the environment. The fires that the natives set
made it easier for the animals to graze and ended up helping the vegetation build up. The late
1900s brought new trees, which are currently still growing, in Pakistan. The trees that used to be
there can no longer grow due to soil degradation. Many are afraid that there will be
desertification in Pakistan soon if these trees are not taken care of because these trees consume
too much water.
SOIL EROSION
Causes
Farming
Agriculture is probably the most significant activity that accelerates soil erosion because of the
amount of land that is farmed and how much farming practices disturb the ground Farmers
remove native vegetation and then plow the land to plant new seeds. Because most crops grow
only in spring and summer, the land lies fallow during the winter. Of course, winter is also the
stormy season in many locations, so wind and rain are available to wash soil away. Tractor tires
make deep grooves, which are natural pathways for water. Fine soil is blown away by wind.
Grazing
Grazing animals wander over large areas of pasture or natural grasslands eating grasses and
shrubs. Grazers expose soil by removing the plant cover for an area. They also churn up the
ground with their hooves. If too many animals graze the same land area, the animals’ hooves pull
plants out by their roots. A land is overgrazed if too many animals are living there.
Construction
Constructing buildings and roads churns up the ground and exposes soil to erosion. In some
locations, native landscapes, such as forest and grassland, are cleared, exposing the surface to
erosion (in some locations the land that will be built on is farmland). Near construction sites, dirt,
picked up by the wind, is often in the air. Completed construction can also contribute to erosion
Effects
The gradual erosion of soil creates sedimentation, a process by which rocks and minerals in the
soil separate from the soil and deposit elsewhere, often lodging in streams and rivers.
Pollutants in the soil, such as fertilizers and pest control agents used to protect crops, also settle
in the streams and rivers. Water pollutants result in poor water quality -- including the quality
of drinking water if the pollutants aren't removed before consumption.
Sedimentation also leads to the excessive growth of algae, as sunlight can get through the
sediment. High levels of algae remove too much oxygen from the water, resulting in the death
of aquatic animals and reduced fish populations , according to the World Wildlife Fund.
Soil Degradation
The degradation of nutrients in soil is often a result of poorly conducted farming and
agricultural practices that lead to soil erosion. Excessive irrigation and outdated tilling
practices reduce the amount of nutrients in the soil and make it less fertile for natural
vegetation and agricultural purposes. According to the Environmental Protection Agency,
agricultural methods, such as purposely leaving organic matter in the soil and ensuring that at
least 30 percent of the previous year's crop residue remain in the soil, increase the fertility and
vitality of the soil. In some cases, seeds can be planted directly in the previous year's crop
residue without any further tillage.
Case study
In certain areas of the Hindu Kush-Himalayas (HKH), ecological situation is depleting day by
day and approaching to the point of no return through gradual environmental degradation.
Surface soil erosion from most of the areas is a serious threat to sustainable agriculture and
sediment accumulation in down stream reservoirs. An extensive study in the Hilkot watershed, a
catchment of Terbala Dam, was started by the People and Resource Dynamics Project in 1998.
Main objectives of this study were to calculate annual runoff and soil losses from different land
uses and compare their seasonal distribution at plot level. Four experimental plots based on land
use classification (i.e. degraded, forests, agricultural, and pasture lands) were established. Area
falls in the monsoon region, about 38% rainfall occurred in the monsoon period (July to
September), while in the pre-monsoon (March to June) and the winter period (October to
February) received 35% and 27% of the total rainfall, respectively. The annual rainfall in the
watershed was 1160 mm. The runoff and soil loss pattern varied among different land use types.
In all the erosion plots, almost 50% of the runoff and soil loss occurred during the monsoon
period and was negligible during winter. The mean maximum runoff was from the degraded plot
(674 m3/ha/y), while minimum was observed from the pasture plot (310 m3/ha/y). Average
runoffs on other land uses were 529 and 460 m3/ha/y, from the forest and agriculture plots,
respectively. Annual soil loss from all land uses ranged between 0.3 to 16.3 t/ha. Average
maximum soil loss was recorded from the degraded plot (6.5 t/ha/y) and average minimum (1.8
t/ha/y) was on the pasture plot. Similarly, average soil from other plots was 3.3 and 3.4 t/ha/y,
measured from the forest and agricultural plots, respectively.
SMOG
Smog is a type of intense air pollution. The word "smog" was coined in the early 20th century,
and is a contraction of the words smoke and fog to refer to smoky fog; its opacity, and odor. This
kind of visible air pollution is composed of nitrogen oxides, sulphur oxides, ozone, smoke and
other particulates. Man-made smog is derived from coal combustion emissions, vehicular
emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these
emissions.
Causes
“Some of the sources for this smog include vehicular pollution with very poor fuel quality being
used along with lack of pollution control technologies in our vehicles, industrial pollution,
burning of municipal and even industrial waste and brick kilns which again use dirty fuel such
as rubber tyres,” says a person who also the Environment and Climate Change Department at
the Sustainable Development Policy Institute, Islamabad.
Effects
Respiratory Health: Studies show that air pollutants contain chemical substances that cause
direct damage to the lungs inner lining and prevent DNA repair of an already damaged inner
lining. Moreover, research shows that the presence of air pollutants in our airways paralyses the
cilia. Up to 35% of total deaths occur due to lung related diseases, caused directly or indirectly
by air pollution, making it the world’s largest health risk.
Cardiovascular Health: Research has found strong independent association of exposure to
ambient air pollutants with development and
progression of cardiovascular disease and risk factors.
In the context of Pakistan, it is critical to realize the
magnitude of the difference in air quality between
countries where these studies were done and air quality
in Pakistan.
Early childhood development: The respiratory compromise directly affects the neuro-
development element in children.
Statistics
Pakistan had the fifth most polluted air in the world in 2016, caused by emissions from vehicles,
industrial activity such as brick kilns, factories, and power plants, and crop burning.
In 2016, 98 percent of Pakistan’s over 200 million people lived in areas where the annual
average particulate pollution level exceeded the WHO guideline.
The areas of Pakistan that face the worst are located along its eastern border, particularly in the
province of Punjab. The most polluted district in the province, as well as in the country, is
Lahore, with a population of 11 million. Air quality in Lahore has declined over the last two
decades. In Faisalabad, Pakistan’s third-largest city, residents lose an average of 4.8 years,
relative to the WHO guideline.
The Pakistani government has begun to respond to the air pollution challenge. In 2017, the
government of Punjab took measures to ban crop burning and enforce emissions regulations on
factories and vehicles. They also shut down coal-fired power plants to control short-term air
pollution, although this led to power outages.
In 2018, Prime Minister Imran Khan came into power and told his cabinet that pollution “is a
serious issue that must be addressed.” Following a court order, his government began to restart
or install air quality monitors. Khan also shuttered factories in 12 highly-polluted districts for
two months in winter, and pushed brick kiln owners to shift to cleaner technologies. Some kiln
operators were fined for using the dirtiest technologies, as have some farmers for their crop
burning. The government is considering setting higher emissions standards for vehicles.
Causes
Pakistan is the 6th most populated country, more waste is being produced than the number of
facilities available to manage it.
Effects
The unavailability of proper disposal methods and resources for solid waste managing results in
various environmental and human health hazard effects. Problems can spread over a wide area.
Health Hazards
As water filters through any material, chemicals in the material may dissolve in the water, a
process called leaching. The resulting mixture is called leachate. As water percolates through
Solid Waste, it makes a leachate that consists of decomposing organic matter combined with
iron, mercury, lead, zinc, and other metals from rusting cans, discarded batteries and appliances.
It may also contain paints, pesticides, cleaning fluids, newspaper inks, and other chemicals.
Contaminated water can have a serious impact on all living creatures, including humans, in an
ecosystem.
Air Pollution
When waste is burnt heavy metals like lead, toxic gases and smoke spreads over residential
areas. The wind also carries waste, dust and gases caused by decomposition. Waste rotting in
sunlight during daytime results in bad smells and reduced visibility.
Case Study
In Lahore, the capital of Punjab and the second largest city in Pakistan, there are currently no
controlled waste disposal facilities are formal recycling systems, though roughly 27% of waste
(by weight) is recycled through the informal sector, Lahore does not have very high performing
governmental management in the waste management situation.
Instead, the City District Government Lahore established the Lahore
Waste Management Company and left the responsibility of the Solid
Waste Management in Lahore to them. Beginning in 2011, Lahore
Waste Management Company strives to develop a system of SWM
that ensures productive collection, recovery, transportation,
treatment and disposal of the waste in Lahore.
Lahore Waste Management Company (LWMC) has over 10,000 field workers involved in waste
collection and disposal. Though the LWMC is working in phases, 100% collection rates are not
seen yet. Lahore currently only has three disposal sites which are no more than dumps, where
illegal dumping and trash burning is common. However, there is some resource recovery taking
place. It is estimated that 27% of dry recyclables are informally recycled within the city.
Additionally a composting plant converts 8% of waste into compost.
In general, the governance over the Waste Management in Lahore is hardly present. Though
there are current projects and plans taking place, by the Lahore Waste Management Company for
example, in order to achieve a productive and sustainable system in the city it is necessary for all
service providers (formal, private, and informal) to take part in decisions and actions.
OVERPOPULATION
Overpopulation In Pakistan
The current world population is about 7.7 billion and increasing at a higher pace. The population
of Pakistan was approximately 100 million; however, the current population of Pakistan is about
210 million. It is expected that the population of
Pakistan can cross 300 million by 2050, which is an
alarming situation for Pakistan.
IMMIGRATION
Afghan Refugees
As of 2017, approximately 1.4 million registered Afghan refugees are in Pakistan while around
1.3 million unregistered Afghan Refugees are also living in Pakistan. They are expected to leave
Pakistan and return to Afghanistan in the coming years. They are mainly found in Khyber
Pakhtunkhwa (KP) and Federally Administered Tribal Areas (FATA) areas, with small numbers
in the cities of Karachi and Quetta. Most of this group were born inside Pakistan in the last 30
years.
Illegal immigrants
In 2012, a Pakistani official claimed that five million illegal immigrants live in Pakistan. Since
early 2002, Pakistan's government took steps to determine the number of illegal immigrants in its
country. The National Alien Registration Authority (NARA) started registering illegal
immigrants in January 2006. According to NARA, there were an estimated 1.8 million illegal
immigrants in Pakistan's commercial capital Karachi in 2007. Others believe that there may be
about 3.35 million illegal immigrants in Pakistan. As of January 2010, the number of illegal
immigrations in Karachi was estimated to be between 1.6 and 2 million. Thousands of nationals
from Afghanistan, Bangladesh, India, Burma, Sri Lanka, Iran, Iraq, Nigeria, Somalia, Jordan,
Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan, and Azerbaijan are illegally living in
Karachi. This includes thousands of Muslim students from Thailand,
the Philippines, Malaysia and Indonesia studying in the Pakistani madrasahs, while thousands of
women from Bangladesh and Burma are working as maids and prostitutes there; most of them
are illegal aliens.
NATURAL DISASTERS
Pakistan is exposed to a variety of natural hazards. The most damaging are cyclones, droughts,
earthquakes, floods, and landslides. In 2005, a high magnitude earthquake caused the greatest
destruction and loss recorded in the country’s history: 6,700 people died; indirect income losses
totaled $576 million; and relief, recovery, and reconstruction cost $5.2 billion.
River Flood.
Coastal Flood.
Landslide.
Urban Flood.
Cyclone.
Wildfire.
Water Scarcity.
Extreme Heat.
Earthquakes:
Pakistan lies within a seismic belt and therefore suffers from frequent small and medium
magnitude earthquakes (GSP 2001). Earthquakes commonly occur along the Himalayas
and Karakorum ranges and parts of Hindu Kush in the north of the country, in the Koh-e-
Suleiman Range in the west with Chaman fault line along Quetta, Zob and Mekran fault
line affects Gawadar district along the sea of the south-west coast.
Cyclones:
According to the World Disaster Report 2003, the 960 km long coastal belt of Pakistan
is occasionally battered by cyclones causing widespread loss to life and property,
especially in the coastal districts of Gawadar, Badin and Thatta.
Floods:
Pakistan is one of the five South Asian countries that have the highest annual average
number of people physically affected by floods (UNDP 2001). The alluvial plains of the
Indus river system formed as flood plains and remain vulnerable to recurrent flooding.
Riverine floods occur during the summer monsoons. Flash floods and landslide hazards
occur frequently in the northern mountains. Districts along the Indus plain are
particularly affected by riverine floods, while hill torrents tend to affect the hilly districts
located in the northern and western parts of Pakistan.
Drought:
Pakistan is one of the countries that is expected to be hit hardest by the effects of
global warming, and drought is one of the possible consequences of global warming
resulting in a sharp fall in water table levels and drying up of wetlands (PMD 2002).
Districts along the south-western and eastern parts of Pakistan have become severely
affected by drought.
CLIMATIC CHANGE
Climate change is expected to cause wide reaching effects on Pakistan. In addition to increased
heat and other extreme weather conditions and drought conditions in some parts of the country,
the melting of glaciers in the Himalayas, threatens the volumetric flow rate of many of the most
important rivers of Pakistan. The foremost hazardous evidence is the rise of carbon dioxide in
out atmosphere. As per NASA’s scientific evidence, for a millennium, the level of carbon
dioxide (parts per million) was below 300, which started to rise since 1950, and is now above
400. Secondly, as per NASA’s evidence, the planet’s average surface temperature has risen about
1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely
by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the
warming occurred in the past 35 years, with the five warmest years on record taking place since
2010. This is also established by the United Nations’ report, prepared by the World
Meteorological Organisation, on September 22, 2019. It states that the period “is currently
estimated to be 1.1 degrees Celsius above pre-industrial era of 1850-1900, and 0.2 degrees
Celsius warmer than 2011-2015”.
The oceans are getting warmer, and ice sheets are shrinking. As per NASA, the oceans have
absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean
showing warming of more than 0.4 degrees Fahrenheit since 1969. The Greenland and Antarctic
ice sheets have decreased and have lost an average of 286 billion tons of ice per year between
1993 and 2016, while Antarctica lost about 127 billion tons of ice per year during the same time
period. The rate of Antarctica ice mass loss has tripled in the last decade.
The glaciers are melting and sea level is rising. Around the globe, the glaciers are retreating
including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa. The global sea level rose
about eight inches in the last century. The rate in the last two decades, however, is nearly double
that of the last century and is accelerating slightly every year.
Pakistan’s water cycle is the primary affected area of climate change. Agriculture is one of the
major sectors likely to be adversely affected by climate change. Climate change can disrupt food
availability, reduce access to food, and affect food quality. Projected increases in temperatures,
changes in precipitation patterns, changes in extreme weather events, and reductions in water
availability may all result in reduced agricultural productivity. Seasonal smog is also due to
climate change and pollution.
Pakistan has also suffered economically due to climate change. According to experts, Pakistan
has faced around 150 freak weather incidents as a result of climate change in the past 20 years:
flash floods, smog in winter, forest fires in summer, melting glaciers, freaky heatwaves,
landslides, displaced population. During the floods in 2010-11, almost 10 percent of Pakistan’s
population was displaced in two provinces, one in the north and another in the south. Last year,
the cost of extreme weather as a consequence of climate change was listed at $384 million; in the
past 20 years, there has been a cost of almost two billion dollars to the national economy because
of the ravages of climate change.
There are other drastic evidences of climate change. Arctic sea ice is declining rapidly. Disturbed
rainfalls and extreme weather events have increased. Also, the ocean acidification, which has
increased by about 30 percent since the Industrial Revolution, is another evidence of climate
change. It also has a negative impact on crop yield productions. The direct impact on the lives of
humans is on the vulnerable and the marginalised segment of society.
SOLUTIONS
Pollution
Take due environmental consideration in planning stage and carefully select business
location with proper location and adequate space for placing exhaust outlets
Avoid the exhaust outlets in close proximity to the air sensitive receptors for restaurants
and food business
Locate the exhaust outlets in a good ventilated and dispersive area, e.g. extending kitchen
exhausts to rooftop
Deforestation
Government Regulations
The best solution to deforestation is to curb the felling of trees by enforcing a series of
rules and laws to govern it. Deforestation in the current scenario may have reduced;
however, it would be too early to assume.
The money-churner nature of forest resources can be tempting enough for deforestation

Banning Clear-Cutting of Forests
This will curb the total depletion of the forest cover. It is a practical solution and is very
feasible.
Reforestation and Afforestation
Land skinned of its tree cover for urban settlements should be urged to plant trees in the
vicinity and replace the cut trees. Also, the cutting must be replaced by planting young
trees to replace the older ones that were cut.
Trees are being planted under several initiatives every year, but they still don’t match the
numbers of the ones we’ve already lost.
Reduce Consumption of Paper
Your daily consumption of paper includes printing paper, notebooks, napkins, toilet
paper, etc. Try to reduce consumption, reduce waste of paper and also opt for recycled
paper products.
Make life simple such as printing/writing on both sides of the paper, using less toilet
paper, avoiding paper plates, and napkins and wherever possible, go paperless.
Educate Others
Still, many are entirely unaware of the global warming problem we’re facing. Educate
your friends, family, and community by sharing the deforestation facts, and its causes and
effects. You can make an impact!
Eat Less Meat
Livestock rearing has become one of the leading causes of deforestation. Try to eat less
meat. It may be hard for some people to try. However, eating less meat, even just for one
meal a day, will also make an extreme impact on the environment.
Soil Erosion
Careful Tilling
Because tilling activity breaks up the structure of the soil, doing less tilling with fewer passes
will preserve more of the crucial topsoil.
Crop Rotation
Plenty of crop rotation is crucial for keeping land happy and healthy. This allows organic matter
to build up, making future plantings more fertile.
Increased Structure For Plants
Introducing terraces or other means of stabilizing plant life or even the soil around them
can help reduce the chance that the soil loosens and erodes. Boosting areas that are prone
to erosion with sturdy plant life can be a great way to stave off future effects.
Water Control
For those areas where soil erosion is predominantly caused by water – whether natural or
man-made – specialized chutes and runoff pipes can help to direct these water sources
away from the susceptible areas, helping stave off excess erosion.
Having these filters in particular areas rather than leading to natural bodies of water is a
focus to reduce pollution.
Soil Conservation
Soil conservation can be defined as “the combination of the appropriate land use and
management practices that promotes the productive and sustainable use of soils and, in
the process, minimizes soil erosion and other forms of land degradation.”
Various measures for soil conservation are primarily meant for the prevention of soil loss
or reduced fertility caused by acidification, over usage, salinization or other chemical soil
contamination.
Different techniques for improved soil conservation involve cover crops, crop rotation,
planted windbreaks, and conservation tillage and affect both fertility and erosion.
Increased Knowledge
A major factor for preventing soil erosion is educating more and more people who work
with the land on why it is a concern, and what they can do to help reduce it.
This means outreach to farmers in susceptible areas for ways that they can help protect
crops from inclement weather or ways that they can help make sure their soil remains
compact without restricting their plant growing activities.
Smog
Instead of throwing away these old clothes, make better use out of it. First, make sure that
these are clothes that you absolutely don’t need any more. Then, donate clothes to people
in need or to Goodwill stores, or hold a sale in your garage (though assuming the clothes
are still wearable, of course). You know what they say, another man’s trash is another
man’s pleasure.
Population
Join local environmental groups, encouraging them to “connect the dots” between
population and the environment and address population issues
Write opinion pieces for local newspapers, contact local media sources requesting more
reporting on population issues – create demand!
Municipalities should set growth management boundaries, discouraging sprawl
development on their fringes
Towns and cities should purchase surrounding lands, or the development rights to such
lands, in order to set them aside as nature preserves and open space
City councils should pass resolutions accepting limits to growth, and directing their
national governments to develop policies to stabilize or reduce national populations
Immigration
Loosen regulations. Make it rasier for migrants to leave their rural hometown and move
to a more urban setting.
Loosen welfare policies. The only reason why people ar not allowed to move freely
inbetween countries, is the construction of the welfare state.
Natural Disasters
Maximum foreseeable loss studies.
Corporate vulnerability assessments.
Insurance purchasing/risk transfer.
Captive insurance development.
Disaster recovery and emergency response planning.
Capital and resource allocation.
Business continuity management and planning.
Building improvement.
Site selection and acquisition.
Climate Change:
BirdLife International delivers ground-breaking research on the causes of the greenhouse
effect, the impacts of climate change and global warming on biodiversity, to inform
better decisions on the ground.
By working to conserve and manage forests, peatlands and other habitats, BirdLife’s
Partnership of 119 national organisations is helping to reduce greenhouse gases in the
atmosphere.
BirdLife supports renewable energy deployment and delivers solutions to governments,
investors and developers to ensure these do not negatively impact nature.
Our work shows that supporting community engagement and action can build the
resilience of natural and societal systems.
CONCLUSION
Environmental problems in coastal regions require a collaborative approach among governments,
civil society, and private interests, presenting a difficult collective action problem.
Environmental problems remain to be resolved. Use of some new forms of energy resources
prompts debates as to adverse consequences, above all to human health.
