Environmental issues in Pakistan
Environmental issues in Pakistan threaten the population’s health and have been disturbing the balance between economic development and environmental protection. As a great problem for the nature and nation of Pakistan and As Pakistan is a large importer of both exhaustible and renewable natural resources and a large consumer of fossil fuels, the Ministry of Environment of Government of Pakistan takes responsibility to conserve and protect the environment.
Water pollution from raw sewage, industrial wastes, and agricultural runoff; limited natural fresh water resources; a majority of the population does not have access to potable water; deforestation; soil erosion; desertification
Little attention was paid to pollution and environmental issues in Pakistan until the early 1990s. Related concerns, such as sanitation and potable water, received earlier scrutiny. In 1987 only about 6 percent of rural residents and 51 percent of urban residents had access to sanitary facilities; in 1990 a total of 97.6 million Pakistanis, or approximately 80 percent of the population, had no access to flush toilets. Greater success has been achieved in bringing potable water within reach of the people; nearly half the population enjoyed such access by 1990. However, researchers at the Pakistan Medical Research Council, recognizing that a large proportion of diseases in Pakistan are caused by the consumption of polluted water, have been questioning the “safe” classification in use in the 1990s. Even the 38 percent of the population that receives its water through pipelines runs the risk of consuming seriously contaminated water, although the problem varies by area. In Punjab, for example, as much as 90 percent of drinking water comes from groundwater, as compared with only 9 percent in Sindh.
The central government’s Perspective Plan (1988–2003) and previous five-year plans do not mention sustainable development strategies. Further, there have been no overarching policies focused on sustainable development and conservation. The state has focused on achieving self sufficiency in food production, meeting energy demands, and containing the high rate of population growth, not on curtailing pollution or other environmental hazards.
In 1992 Pakistan’s National Conservation Strategy Report attempted to redress the previous inattention to the nation’s mounting environmental problem. Drawing on the expertise of more than 3,000 people from a wide array of political affiliations, the government produced a document outlining the current state of environmental health, its sustainable goals, and viable program options for the future.
Karachi is the financial capital of Pakistan
Of special concern to environmentalists is the diminishing forest cover in watershed regions of the northern highlands, which has only recently come under close scrutiny. Forest areas have been thoughtlessly denuded. Deforestation, which occurred at an annual rate of 0.4 percent in 1989-90, has contributed directly to the severity of the flooding problem faced by the nation in the early 1990s.
As industry has expanded, factories have emitted more and more toxic effluents into the air and water. The number of textile and food processing mills in rural Punjab has grown greatly since the mid-1970s, resulting in pollution of its rivers and irrigation canals. Groundwater quality throughout the country has also suffered from rapidly increasing use of pesticides and fertilizers aimed at promoting more intensive cropping and facilitating self-sufficiency in food production.
The National Conservation Strategy Report has documented how solid and liquid excreta are the major source of water pollution in the country and the cause of widespread waterborne diseases. Because only just over half of urban residents have access to sanitation, the remaining urban excreta are deposited on roadsides, into waterways, or incorporated into solid waste. Additionally, only three major sewage treatment plants exist in the country; two of them operate intermittently. Much of the untreated sewage goes into irrigation systems, where the wastewater is reused, and into streams and rivers, which become sewage carriers at low-flow periods. Consequently, the vegetables grown from such wastewater have serious bacteriological contamination. Gastroenteritis, widely considered in medical circles to be the leading cause of death in Pakistan, is transmitted through waterborne pollutants.
Low-lying land is generally used for solid waste disposal, without the benefit of sanitary landfill methods. The National Conservation Strategy has raised concerns about industrial toxic wastes also being dumped in municipal disposal areas without any record of their location, quantity, or toxic composition. Another important issue is the contamination of shallow groundwater near urban industries that discharge wastes directly into the ground.
Water in Karachi is so contaminated that almost all residents boil it before consuming it. Because sewerage and water lines have been laid side by side in most parts of the city, leakage is the main cause of contamination. High levels of lead also have been found in water in Islamabad and Rawalpindi.
Air pollution has also become a major problem in most cities. There are no controls on vehicular emissions, which account for 90 percent of pollutants. The National Conservation Strategy Report claims that the average Pakistani vehicle emits twenty-five times as much carbon monoxide, twenty times as many hydrocarbons, and more than three and one-half times as much nitrous oxide in grams per kilometer as the average vehicle in the United States.
Another major source of pollution, not mentioned in the National Conservation Strategy Report, is noise. The hyper-urbanization experienced by Pakistan since the 1960s has resulted in loose controls for heavy equipment operation in densely populated areas, as well as in crowded streets filled with buses, trucks, automobiles, and motorcycles, which often honk at each other and at the horse-drawn tongas (used for transporting people) and the horse-drawn rehras (used for transporting goods).
Pakistan is subject to frequent earthquakes which are often severe (especially in north and west) and severe flooding along the Indus after heavy rains (July and August). Landslides are common in the northern mountains.
New data from millennium-long tree-ring analyses are indicating that mountains in northern Pakistan have grown significantly weter over the past century than they had been over the last millennium — quite possibly due to human-induced global warming. In Karakoram and Himalaya mountains in northern Pakistan, the upper reaches of the Indus Valley (which supplies the world’s largest irrigation network), a group of researchers collected samples of Juniper tree rings that dated back as far as 828.
The availability of natural resources is limited by the dry climate and mountainous terrain, substantial population growth is increasing pressure on the resource base, and resource management has suffered from the emphasis on rapid economic growth and often-unregulated forms of economic productivity. As a result, human transformation of the environment is manifest in several problems. Population growth and poor water infrastructure have reduced per capita water availability from 53,000 cubic meters to 1,200 cubic meters, and heavy reliance on firewood has contributed to the world’s second highest rate of deforestation. Poor agricultural practices have led to soil erosion, groundwater degradation, and other problems that have hindered crop output and contributed to health problems for rural communities. Solid waste burning, low-quality fuels, and the growing use of fuel-inefficient motor vehicles have contributed to air pollution that in some cities—such as Karachi, Islamabad, Lahore, Peshawar, Quetta, Faisalabad and Rawalpindi—has exceeded levels deemed safe by the World Health Organization. And Pakistan is suffering a lot from droughts from the dry climates.
The government has expressed concern about environmental threats to economic growth and social development and, since the early 1990s, has addressed environmental concerns with new legislation and institutions such as the Pakistan Environment Protection Council. Yet, foreign lenders provide most environmental protection funds, and only 0.04 percent of the government’s development budget goes to environmental protection. Thus, the government’s ability to enforce environmental regulations is limited, and private industries often lack funds to meet environmental standards established by international trade organizations.
To conclude all the above mentioned points, the confronting current facing issues in Pakistan regarding to water is mainly contribution of agricultural practices (pesticides, fertilizers etc leading to surface water causing eutripication and make it impaired quality for drinking purpose and aquatic life). The Government should take some efficient mitigation measures to avoid such types of practices. Industrial emissions causing many acute and chronic diseases in human as well as animals (headache, dhirea, itching, burning, suffocation, kidney problems, and many other infections). Some anthropogenic activities making human prone to natural disasters. Climatic variations caused by the emissions like manmade activities has altered the overall scenario of the environment, which hugely effected the economy of the community. To avoid the predicted and happened adverse effects of manmade activities and natural disasters there must be awareness and followed legislations in favor of both nature and Environment.
