Geography, resources & the regions of Pakistan

Location and strategic frontiers

Pakistan occupies the north-western quadrant of South Asia between roughly 24°N and 37°N latitude and 61°E and 77°E longitude, spanning an area of 881,913 sq km (excluding Pakistan-administered Kashmir). It shares land borders with four states: India along the 3,323 km boundary fixed substantially by the Radcliffe Award of 17 August 1947 and the Line of Control demarcated by the Simla Agreement (2 July 1972) and the Karachi Agreement (27 July 1949); Afghanistan along the 2,640 km Durand Line agreed between Sir Mortimer Durand and Amir Abdur Rahman Khan on 12 November 1893; Iran along a 909 km frontier settled by the Goldsmid Line (1871); and China along a 523 km boundary fixed by the Sino-Pakistan Boundary Agreement of 2 March 1963. Its 1,046 km Arabian Sea coastline gives it the deep-water ports of Karachi, Port Qasim and Gwadar.

Relief: from the Himalaya to the delta

Pakistan's topography descends from the world's highest mountain knot to a sea-level delta. The north hosts the convergence of three ranges — the Himalaya, the Karakoram and the Hindu Kush — meeting near Jaglot. K-2 (Mount Godwin-Austen, 8,611 m) in the Karakoram is the second-highest peak on earth; Nanga Parbat (8,126 m) anchors the western Himalaya. The Khyber, Kurram, Tochi, Gomal and Bolan passes pierce the western mountains and have historically been the invasion and trade corridors into the subcontinent.

South of the mountains lies the Potohar Plateau, dissected and home to the Salt Range and the Khewra salt mine (the world's second largest, exploited since antiquity). The Indus Plain — the agricultural and demographic heartland — stretches from the Punjab doab country to the Sindh lowlands and the Indus delta. To the west rise the Balochistan Plateau and the Sulaiman and Kirthar ranges; to the south-east lies the Thar Desert and the Cholistan.

The Indus river system

The Indus (Sindhu), 3,180 km long, is the lifeline of the state. Its principal tributaries are the five rivers of the Punjab — the Jhelum, Chenab, Ravi, Beas and Sutlej. The Indus Waters Treaty, signed at Karachi on 19 September 1960 between President Ayub Khan and Prime Minister Jawaharlal Nehru under World Bank mediation (signatory W.A.B. Iliff), allocated the three western rivers (Indus, Jhelum, Chenab) to Pakistan and the three eastern rivers (Ravi, Beas, Sutlej) to India. Pakistan financed replacement works — Mangla Dam (1967) on the Jhelum and Tarbela Dam (1976) on the Indus, the latter among the world's largest earth-filled dams — to compensate for the lost eastern flows. Candidates must retain these dates and the treaty's allocation logic, the most heavily examined geography fact in the paper.

Mineral and energy endowment

Pakistan's mineral wealth is concentrated but underexploited. The Sui gas field in Balochistan, discovered in 1952, was the foundation of the national gas economy. The Reko Diq copper-gold deposit in Chagai district, one of the largest undeveloped reserves on earth, became the subject of a $5.9 billion ICSID arbitration award (2019) before a renegotiated settlement with Barrick Gold in 2022. The Saindak copper-gold project, the Thar coalfield (estimated at over 175 billion tonnes of lignite, among the largest coal reserves globally), the Khewra and Kalabagh salt deposits, and chromite in Muslim Bagh complete the picture. Energy supply rests on a thermal-dominated mix supplemented by hydropower (Tarbela, Mangla, Ghazi-Barotha, Neelum-Jhelum), the Chashma and Karachi (KANUPP/K-2/K-3) nuclear plants, and growing solar and wind capacity in the Gharo-Jhimpir corridor.

Climate and agriculture

Four seasons govern Pakistan: cool dry winter (December–February), hot dry spring (March–May), the south-west monsoon summer (June–September), and the retreating monsoon (October–November). Rainfall is highly variable — over 1,500 mm in the northern sub-mountain belt against under 125 mm in much of Balochistan and Sindh — making the country one of the most water-stressed in the world, below the 1,000 cubic metre per capita scarcity threshold. Agriculture, dependent on the world's largest contiguous canal irrigation system, contributes roughly a fifth of GDP and employs nearly 38% of the labour force; wheat, cotton, rice, sugarcane and maize are the principal crops.

The provinces and territories

Pakistan is a federation of four provinces and the Islamabad Capital Territory, plus the autonomous regions of Azad Jammu & Kashmir and Gilgit-Baltistan. Punjab (capital Lahore) is the most populous, the wheat-cotton granary and the political pivot. Sindh (Karachi) contains the commercial capital and chief ports. Khyber Pakhtunkhwa (Peshawar) absorbed the former FATA through the Twenty-Fifth Amendment (31 May 2018), which merged the tribal areas into the province. Balochistan (Quetta) is the largest by area (44% of the territory) yet least populous, holding the bulk of mineral and gas wealth and the port of Gwadar, the southern terminus of the China-Pakistan Economic Corridor launched in April 2015. The 2023 digital census recorded a population of roughly 241.5 million, the fifth-largest on earth. Mastery of provincial capitals, areas, resource bases and the FATA merger is indispensable.

Why this matters for the exam

Geography is examined in the CSS Pakistan Affairs compulsory paper both as a discrete question and as the factual substrate beneath economy and foreign-policy answers. The Federal Public Service Commission has historically set direct questions on the Indus Waters Treaty, on Pakistan's water crisis, on CPEC and Gwadar, and on the location and significance of mineral deposits such as Reko Diq, Thar coal and Saindak. A candidate who cannot state the treaty's allocation (three western rivers to Pakistan, three eastern to India), name Mangla (1967) and Tarbela (1976), and identify the four provincial capitals will forfeit easy marks.

How it is tested

The paper rewards the fusion of geography with policy. A strong answer on the water crisis names the 1,000 cubic-metre scarcity threshold, cites the Indus Waters Treaty and the Kishanganga arbitration (Permanent Court of Arbitration partial award, 18 February 2013), references storage shortfall against the loss of Indian eastern-river flows, and proposes the Diamer-Bhasha and Mohmand dams as remedies. An answer on regional disparity should marshal Balochistan's 44% landmass against its sub-6% population, its gas and mineral wealth, and the political grievance over royalties and Gwadar.

High-yield facts to retain

Memorise: area 881,913 sq km; four land neighbours with their boundary instruments and dates (Radcliffe 1947, Durand 1893, Goldsmid 1871, Sino-Pak 1963); the coastline of 1,046 km and three ports; K-2 at 8,611 m; the Indus at 3,180 km and its five Punjab tributaries; the Indus Waters Treaty of 19 September 1960; Tarbela and Mangla; Thar coal, Reko Diq, Saindak, Sui, Khewra; the four passes (Khyber, Bolan, Gomal, Tochi); and the Twenty-Fifth Amendment FATA merger of 31 May 2018. These anchor facts convert a vague essay into a marks-bearing one, and they recur across past-year questions with high frequency.
