GEOGRAPHY OF PAKISTAN:
The geography of Pakistan is profoundly a mixture of landscapes varying from mostly plains to deserts, forests, hills, and plateaus ranging from the coastal areas of the Arabian Sea in the south to the mountains of the Karakoram Range in the north. Pakistan geologically overlaps both with the Indian and the Eurasian tectonic plates where its Sindh and Punjab province lie on the north-western corner of the Indian plate while Balochistan and most of the North-West Frontier Province lies within the Eurasian plate which mainly comprises the Iranian plateau, some parts of the Middle East and Central Asia. The Northern Areas and Azad Kashmir lie mainly in Central Asia along the edge of the Indian plate and hence are prone to severe earthquakes where the two tectonic plates collide.
Pakistan is bordered by Afghanistan to the north-west and Iran to the west while the People's Republic of China borders the country in the north and India to the east. The nation is geopolitically placed within some of the most controversial regional boundaries which share disputes and have many-a-times escalated military tensions between the nations, e.g., that of Kashmir with India and the Durand Line with Afghanistan. Its western borders include the Khyber Pass and Bolan Pass that have served as traditional invasion routes between Central Eurasia and South Asia.

INTERNATIONAL BOUNDARIES:

Pakistan shares its borders with four neighboring countries – Afghanistan, China, India, and Iran – adding up to about 6,975 km (4,334.1 mi) in length (excluding the coastal areas).
Pakistan officially borders with Afghanistan at the Durand Line, 2,643 km (1,642.3 mi), which runs from the Hindu Kush and the Pamir Mountains. From the eastern tip of the Wakhan Corridor starts the Sino-Pak border between the People's Republic of China and Pakistan spanning about 510 km (316.9 mi). It carries on south-eastward and ends near the Karakoram Pass. The boundary with Iran, 912 km (566.7 mi), was first delimited by a British commission in the same year as the Durand Line was demarcated; separating Iran from what was then British India's Baluchistan province. Modern Iran has a province named Sistan va Baluchistan that borders Pakistan and has Baluchis in an ethnic majority. The Pakistan-India ceasefire line runs from the Karakoram Pass west-southwest to a point about 130 kilometers northeast of Lahore. This line, about 770 kilometers long, was arranged with United Nations (UNO) assistance at the end of the Indo-Pakistani War of 1947-48. The ceasefire line came into effect on January 1, 1949, after eighteen months of fighting between Indian forces and Afridi tribals which Pakistan had send to occupy Kashmir and was last adjusted and agreed upon by the two countries according to the Simla Agreement of July 2, 1972 between Indira Gandhi and Zulfikar Ali Bhutto. Since then, it has been generally known as the Line of Control or the (LoC).
The southern borders are far less contentious than those in northern Pakistan (Kashmir). The Thar Desert in the province of Sindh is separated in the south from the salt flats of the Rann of Kachchh (Kutch) by a boundary that was first delineated in 1923-24.


GEOGRAPHICAL REGIONS:



Pakistan is divided into three major geographic areas: the northern highlands; the Indus River plain, with two major subdivisions corresponding roughly to the provinces of Punjab and Sindh; and the Balochistan Plateau. Some geographers designate additional major regions. For example, the mountain ranges along the western border with Afghanistan are sometimes described separately from the Balochistan Plateau, and on the eastern border with India, south of the Sutlej River, the Thar Desert may be considered separately from the Indus Plain.

THE NORTHERN HIGHLANDS

The northern highlands include parts of the Hindu Kush, the Karakoram Range, and the Himalayas. This area includes such famous peaks as K2 (Mount Godwin Austen, at 8,611 meters the second highest peak in the world), and Nanga Parbat (8,126 m), the twelfth highest. More than one-half of the summits are over 4,500 meters, and more than fifty peaks reach above 6,500 meters. Travel South of the northern highlands and west of the Indus River plain are the Safed Koh Range along the Afghanistan border and the Sulaiman Range and Kirthar Range, which define the western extent of the province of Sindh and reach almost to the southern coast


THE INDUS PLAIN




The name Indus comes from the Sanskrit word sindhu, meaning ocean, from which also come the words Sindh, Hindu, and India. The Indus, one of the great rivers of the world, rises in southwestern Tibet only about 160 kilometers west of the source of the Sutlej River, which joins the Indus in Punjab, and the Brahmaputra, which runs eastward before turning southwest and flowing through Bangladesh. The catchment area of the Indus is estimated at almost 1 million square kilometers, and all of Pakistan's major rivers--the Kabul, Jhelum, Chenab, Ravi, and Sutlej--flow into it. The Indus River basin is a large, fertile alluvial plain formed by silt from the Indus. This area has been inhabited by agricultural civilizations for at least 5,000 years.
The upper Indus Basin includes Punjab; the lower Indus Basin begins at the Panjnad River (the confluence of the eastern tributaries of the Indus) and extends south to the coast. In Punjab (meaning the "land of five waters") are the Indus, Jhelum, Chenab, Ravi, and Sutlej rivers. Pakistan has two major river dams: the Tarbela Dam on the Indus, near the early Buddhist site at Taxila, and the Mangla Dam on the Jhelum, where Punjab borders Azad Kashmir built as part of the Indus Basin Project. The Warsak Dam on the Kabul River near Peshawar is smaller. These dams, along with a series of head works and barrages built by the British and expanded since independence, are of vital importance to the national economy and played an important role in calming the raging floodwaters of 1992, which devastated large areas in the northern highlands and the Punjab plains.

THE BALOCHISTAN PLATEAU




Balochistan is located at the eastern edge of the Iranian plateau and in the border region between Southwest, Central, and South Asia. It is geographically the largest of the four provinces at 347,190 km² or (134,051 square miles) of Pakistani territory. The Sulaiman Mountains dominate the northeast corner and the Bolan Pass is a natural route into Afghanistan towards Kandahar. Much of the province south of the Quetta region is sparse desert terrain with pockets of inhabitable towns mostly near rivers and streams. This area is subject to frequent seismic disturbances because the tectonic plate under the Indian plate hits the plate under Eurasia as it continues to move northward and to push the Himalayas ever higher. The region surrounding Quetta is highly prone to earthquakes. A severe quake in 1931 was followed by one of more destructive force in 1935. The small city of Quetta was almost completely destroyed, and the adjacent military cantonment was heavily damaged. At least 20,000 people were killed.

CLIMATE:

Pakistan lies in the temperate zone. The climate is mostly semi-arid, but arid in the south, characterized by hot summers and cool or cold winters, and wide variations between extremes of temperature at given locations. There is little rainfall. These generalizations should not, however, obscure the distinct differences existing among particular locations. For example, the coastal area along the Arabian Sea is usually warm, whereas the frozen snow-covered ridges of the Karakoram Range and of other mountains of the far north are so cold year round that they are only accessible by world-class climbers for a few weeks in May and June of each year. Pakistan has four seasons: a cool, dry winter from December through February; a hot, dry spring from March through May; the summer rainy season, or southwest monsoon period, from June through September; and the retreating monsoon period of October and November. The onset and duration of these seasons vary somewhat according to location.
CLIMATIC CHANGES:
New data from millennium-long tree-ring analyses are indicating that mountains in northern Pakistan have grown significantly wetter over the past century than they have 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.

NATIONAL CONSERVATION GOALS:
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, in addition, often transports excess agricultural chemicals resulting in contaminated runoff. This runnoff 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. 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. 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 2 years, This is a dramatic change and puts emphasis on Climate Change Campaigns.

NATURAL RESOURCES

Pakistan's principal natural resources are arable land, water, and extensive natural gas and oil reserves. About 28% of Pakistan's total land area is under cultivation and is watered by one of the largest irrigation systems in the world. The most important crops are cotton, wheat, rice, sugarcane, maize, sorghum, millets, pulses, oil seeds, barley, fish, fruits and vegetables, which together account for more than 75% of the value of total crop output. Pakistan also exports wood, cement, tiles, marbles, cotton textiles, leather goods, sports goods, surgical instruments, electrical appliances, carpets, rugs, and hides & skins. The Salt Range in Punjab Province has large deposits of pure salt. Pakistan has extensive energy resources, including fairly sizable natural gas reserves, oil reserves, coal, gypsum, limestone, chromites, iron ore, rock salt, silver, gold, precious stones, gems, marbles, tiles, copper, sulfur, fire clay, silica sand, and large hydropower potential. However, the exploitation of energy resources has been slow due to a shortage of capital and domestic and international political constraints.
