Pakistan and Bangladesh

Pakistan: Located on the northwestern edge of the Indian subcontinent, bordering Afghanistan, China, and India.
Bangladesh: Located on the northeastern edge, almost entirely surrounded by India with a small border with Myanmar.
Mountain Ranges (Pakistan): The Himalaya, Karakoram, and Hindu Kush. Northern peaks range from $13,000\,\text{feet}$ ( $3,962\,\text{m}$ ) to over $25,000\,\text{feet}$ ( $7,620\,\text{m}$ ).
K2: The world's second-highest peak at $28,250\,\text{feet}$ ( $8,611\,\text{m}$ ), located in the Karakoram.
Key Passes: The Khyber Pass (strategic border with Afghanistan), Khunjerab Pass (link to China), and Bolan Pass.
Landscape Features: Pakistan features the Baluchistan Plateau, the Thar Desert, and the Indus River valley (Punjab and Sind). Bangladesh is largely flat, containing the Haor Basin wetlands, Mount Keokradong ( $4,035\,\text{feet}$ / $1,230\,\text{m}$ ), and the Sundarbans mangrove forest.

Major Rivers: The Indus (Pakistan) and the Ganges, Brahmaputra (called Padma and Jamuna in Bangladesh), and Meghna (Bangladesh).
Delta System: Bangladesh contains the largest delta system in the world where major rivers empty into the Bay of Bengal.
Hydroelectric Power: Generated via the Mangla Dam and Tarbela Dam in Pakistan. Bangladesh's flat terrain limits hydroelectric potential.
Climate: Monsoon-driven with three seasons (hot, hot/wet, and cool). Southeastern Bangladesh has a tropical wet climate with up to $60\,\text{inches}$ ( $152\,\text{cm}$ ) of annual rain. Southern Pakistan has an arid desert climate.
Natural Hazards: Cyclones (Bangladesh averages 16 every 10 years), tsunamis, and seasonal flooding.

Early Civilizations: Mehrgarh (7000 B.C.) and the Indus River valley culture (2500 B.C.) at Mohenjo Daro.
Religious Origins: Islam arrived via Muslim traders in the A.D. 700s (Pakistan) and 800s (Bangladesh); both later became part of the Mogul Empire.
Partition of 1947: British India was split into India (predominantly Hindu) and Pakistan (predominantly Muslim). Pakistan consisted of East and West sections separated by $1,000\,\text{miles}$ ( $1,609\,\text{km}$ ).
Independence of Bangladesh: Formerly East Pakistan, it declared independence in 1971 following ethnic tensions, linguistic disputes (Urdu vs. Bangla), and a civil war supported by India.
Modern Governance: Both are parliamentary republics. Current/Recent leaders include Asif Ali Zardari and Nawaz Sharif (Pakistan) and Sheikh Hasina (Bangladesh).

Population Stats: Pakistan is the 6th most populous ( $180\,\text{million}$ ); Bangladesh is 8th ( $153\,\text{million}$ ).
Population Density: Bangladesh is the most densely populated South Asian country at $3,256\,\text{people/sq\,mi}$ ( $1,257\,\text{people/sq\,km}$ ).
Ethnicity and Language: Pakistan is diverse (Punjabis at $45\%$ , Pashtuns, Sindhis); Bangladesh is primarily ethnic Bengali.
Social Indicators: Literacy rates are below $60\%$ in both countries. Poverty is widespread and healthcare is prioritized low.
Cultural Arts: Qawwali music and public musha'irahs (poetry recitals) in Pakistan; Rabindranath Tagore and Kazi Nazrul Islam are iconic Bengali literary figures.

Agriculture: Half of the workforce in Pakistan and a large portion in Bangladesh. Major crops include rice, cotton, sugarcane (Pakistan), and jute (Bangladesh).
Industry: Garment and textile manufacturing dominates exports. Karachi is Pakistan's primary port.
Aquaculture: Bangladesh is a major producer of inland fish and shrimp.
Total Fertilty Rates: $3.6$ in Pakistan; decreased to $2.2$ in Bangladesh due to loan programs for women and education.

Sustainable Development Principles: Defined by promoting economic growth, protecting the environment, and ensuring social fairness.
Specific Threats: Soil salinity (Indus valley), deforestation in northern Pakistan and the Sundarbans, and severe air pollution in cities like Lahore and Peshawar.
Strategic Responses: Pakistan's use of compressed natural gas (CNG) vehicles; Bangladesh's composting of animal waste and creation of nature reserves for Bengal tigers.
Obstacles: Lack of funding, corruption, and the urgent need for short-term survival among the poor.
