By 2050, 2 billion more people will live in urban
slums, where:
➜ 75% lack durable housing, leaving families vulnerable to
floods, fires, and disease.
➜ Construction emits 40% of global CO₂, worsening climate
risks for the urban poor.
➜ Traditional solutions fail—concrete is expensive,
relocation disrupts communities, and temporary shelters
degrade quickly.
