The majority of Pakistan’s industrial sectors, for example fishing and agriculture, which count for more than one fourth of the output and two fifths of employment in Pakistan, are highly dependent on the country's natural resources. Hence in order to sustain economic growth there is a high demand on already scare natural resources. However it is ironic that what the country depends on for its growth is also what threatens the future welfare and success of the country. According to the World Bank, 70% of Pakistan’s population live in rural areas and are already stricken by high poverty levels. These people depend on natural resources to provide income and tend to overuse these resources. This leads to further degradation of the environment and subsequently increases poverty. This has led to what the World Bank refers to as a "vicious downward spiral of impoverishment and environmental degradation."
The World Bank report in 2013 stated that Pakistan's top environmental issues include air pollution, inadequate supply of uncontaminated drinking water, noise pollution and the health deterioration of urban and rural populations due to pollution. These environmental concerns not only harm Pakistani citizens but also pose a serious threat to the country's economy. The report also stated that the increase in industrialization, urbanization and motorization will inevitably worsen this problem.
Pakistan faces a major scarcity when it comes to water resources, especially finding clean water. There is only one major river, the Indus River, which supplies water throughout the agricultural plains in Punjab and in Sindh, while the rest of the country has very little access to other fresh water. The scarcity of water not only threatens Pakistan's economy but also poses a serious threat to the lives of millions of Pakistanis.
The issue of water pollution further worsens this problem for Pakistan. The sources for water pollution include the overuse of chemical fertilizers, the dumping of industrial wastes into lakes and rivers, untreated sewage being dumped into the ocean, and contaminated pipelines being used to transport water. The contamination of fresh drinking water makes it harder for people to find clean water supplies and increases the prevalence of waterborne diseases. Consequently, most of the reported health problems in Pakistan are either a direct or indirect result of polluted water. 45% of infant deaths are due to diarrhea and 60% to overall waterborne diseases.
The megacities of Pakistan, such as Karachi, Lahore, Islamabad and Rawalpindi, face the issue of noise pollution. The main source of this pollution is the traffic noise caused by busses, cars, trucks, rickshaws and water tankers. A study showed that on one of Karachis main roads the average noise level was around 90 dB and was capable of reaching about 110 dB. This is much higher than the ISO's noise level standard of 70 dB, which is not meant to be harmful to the human ear. However the study also concluded that in Pakistan, "the traffic noise levels limit as laid down by National Environment Quality standards, Environmental Protection Agency is 85 dB".
This high level of noise pollution can cause auditory and non-auditory health issues. Auditory issues include the loss of auditory sensory cells; non-auditory health issues include sleep disturbance, noise and cardiovascular disease, endocrine response to noise and psychiatric disorder. Unfortunately there are very few, vague laws and policies in regards to noise levels. There is no accountability, and while the federal and provincial environmental protection agencies receive dozens of complaints on noise pollution from the public, these agencies are unable to take action due to legal constraints and the absence of national noise level standards.
Air pollution is a growing environmental problem in Pakistan, especially in the large metropolises. According to a World Bank report, "Pakistan's urban air pollution is among the most severe in the world and it engenders significant damages to human health and the economy". The inefficient use of energy, an increase in the number of vehicles used daily, an increase in unregulated industrial emissions and the burning of garbage and plastic have contributed the most to air pollution in urban areas. According to a recent study, Pakistan's Environment Protection Department claims that the average level of pollution in big cities is approximately four times higher than the World Health Organisation's limits. These emissions have detrimental effects, including "respiratory diseases, reduced visibility, loss of vegetation and an effect on the growth of plants."
One of the greatest contributors to air pollution is industrial activity. The inadequate air emission treatments and lack of regulatory control over industrial activity has contributed to the deterioration of ambient air quality in major cities. In addition, the common practice of burning massive amounts of solid waste, including plastic and rubber, on street corners by the public, releases toxic gases, which are extremely harmful for residents in the area.
Climate change has affected the people and the environment of Pakistan in different ways. Although Pakistan is a relatively small emitter of greenhouse gas as compared to other countries, the country will, however, be greatly affected by the negative impacts of climate change. According to the Pakistan Economic Survey of 2014-15, the "increase in frequency and intensity of extreme weather events coupled with erratic monsoon rains causing frequent and intense floods and droughts" are the most prominent problems Pakistan will face due to climate change. The survey concluded that the change in weather patterns has destroyed infrastructures, has taken many lives and has had devastating impacts on the agriculture sector, which has in turn has affected Pakistan’s economy.
According to the BBC Climate Asia report, the majority of the Pakistani people surveyed claimed that climate change has heavily impacted their lives in the form of floods and droughts, and most importantly has affected the availability of resources such as energy and water. 53% of Pakistanis felt that their lives had become worse off than they were five years ago. Although the effects of climate change are evident, the survey found that the majority of the people were unaware of the meaning of climate change, and "ascribed changes in climate and extreme weather events to the will of God."
Due to Pakistan's diverse land and climatic conditions, it is prone to different forms of natural disasters, including earthquakes, floods, tsunamis, droughts, cyclones and hurricanes. A disaster management report claims that the provinces of Gilgit-Baltistan (GB), Balochistan and AJK are vulnerable seismic regions and hence highly susceptible to earthquakes, while Sindh and Punjab constantly suffer from floods because they are low-lying areas.
Some of the worst natural disasters that Pakistan has faced include the 1935 Quetta earthquake when around 60000 people were killed, the 1950 floods when an estimated 2900 people died and 900000 people were left homeless, the 1974 Hunza earthquake where around 5300 people were killed, the 2005 Kashmir quake that killed at least 73000 and affected more than 1.5 million people, and the Pakistan floods of 2010 where 20 million people were affected.
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. However, 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 the funds to meet environmental standards established by international trade organizations.
The National Conservation Strategy Report has three explicit objectives: conservation of natural resources, promotion of sustainable development, and improvement of efficiency in the use and management of resources. It sees itself as a "call for action" addressed to central and provincial governments, businesses, non-governmental organizations (NGOs), local communities, and individuals.
The primary agricultural nonpoint source pollutants are nutrients (particularly nitrogen and phosphorus), sediment, animal wastes, pesticides, and salts. Agricultural nonpoint sources enter surface water through direct surface runoff or through seepage to ground water that discharges to a surface water outlet. Various farming activities result in the erosion of soil particles. The sediment produced by erosion can damage fish habitat and wetlands, and often transports excess agricultural chemicals resulting in contaminated runoff. This runoff in turn affects changes to aquatic habitat such as temperature increases and decreased oxygen. The most common sources of excess nutrients in surface water from nonpoint sources are chemical fertilizers and manure from animal facilities. Such nutrients cause eutrophication in surface water. Pesticides used for pest control in agricultural operations can also contaminate surface as well as ground-water resources. Return flows, runoff, and leach ate from irrigated lands may transport sediment, nutrients, salts, and other materials. Finally, improper grazing practices in riparian areas, as well as upland areas, can also cause water quality degradation. The development of Pakistan is viewed as a multigenerational enterprise.
In seeking to transform attitudes and practices, the National Conservation Strategy recognizes that two key changes in values are needed: the restoration of the conservation ethic derived from Islamic moral values, called Qantas, and the revival of community spirit and responsibility, Aquila-UL-bad.
The National Conservation Strategy Report recommends fourteen program areas for priority implementation: maintaining soils in croplands, increasing efficiency of irrigation, protecting watersheds, supporting forestry and plantations, restoring rangelands and improving livestock, protecting water bodies and sustaining fisheries, conserving biodiversity, increasing energy efficiency, developing and deploying renewable resources, preventing or decreasing pollution, managing urban wastes, supporting institutions to manage common resources, integrating population and environmental programs, and preserving the cultural heritage. It identifies sixty-eight specific programs in these areas, each with a long-term goal and expected outputs and physical investments required within ten years. Special attention has been paid to the potential roles of environmental NGOs, women's organizations, and international NGOs in working with the government in its conservation efforts. Recommendations from the National Conservation Strategy Report are incorporated in the Eighth Five-Year Plan (1993–98).
In a recent study conducted by Global CLEAN campaign, it was found that the average temperature in Pakistan had risen by .2 degrees in only two years, This is a dramatic change and puts emphasis on climate change campaigns.
