🧠 Memory Aid: TRAFFIC

Use the acronym TRAFFIC to remember the key challenges facing megacities. Each letter gives you a topic to write about in an exam answer:

T — Traffic congestion (Mumbai: 10 km/h; Dhaka: 7 km/h — costs Bangladesh 3% of GDP annually)

R — Resources under strain (water, electricity, food systems overwhelmed by rapid growth)

A — Air pollution (Mumbai PM2.5 levels 5× WHO limit; 7 million deaths/year globally from urban air pollution)

F — Flooding and environmental risk (Dhaka: 70% below 6m sea level; Mumbai 2005: 944mm in 24 hours)

F — Finances and informal economy (60% of LIC urban workers in informal economy without legal protections)

I — Informal settlements / Infrastructure gap (1 billion people in informal settlements globally; infrastructure always lags population)

C — Congestion of services (schools, hospitals, waste collection overwhelmed — Dhaka generates 35,000 tonnes waste/day)

For case study data, use this quick memory frame:

Global facts: 37 megacities in 2024 | 90% of growth in LICs/NEEs | 1 billion in informal settlements | 2050: Africa's urban population triples
