Managing Urban Growth: Favelas
What is a Favela?
Definition: Informal settlements built on marginal land (steep hillsides) without permission, with inadequate infrastructure. Also called slums or squatter settlements.
Why Favelas Form
- • Rural migrants can't afford formal housing
- • Occupy vacant land (steep hills, flood-prone areas)
- • Self-build shelters from scrap materials
- • Wood, corrugated iron, brick construction
Favela Characteristics
- • Density: Extremely overcrowded, narrow alleys
- • Buildings: Improvised, unsafe structures
- • Services: Limited water, illegal electricity
- • Tenure: No legal ownership = eviction risk
Example: Rocinha
Rio's largest favela with 70,000-100,000 residents on a steep hillside in the South Zone. Houses crammed together with narrow alleys (no vehicle access), located between wealthy neighbourhoods and overlooking luxury apartments - a stark visual symbol of inequality.
Grade 8/9 Key Point: Favelas are NOT just "slums of despair" - many have strong communities, local businesses, vibrant culture, and residents who have lived there for generations. BUT infrastructure deficits create severe challenges that require systemic solutions.

Social Challenges
- • Only 50% favela households have piped water
- • Rest use communal taps or illegal connections
- • Water quality unreliable - contamination from sewage
- • 12% of favelas have NO sanitation at all
- • Open sewers run down hillsides
- • Disease risk: diarrhea, cholera outbreaks
- • Illegal taps into grid = fire/electrocution risk
- • Estimated 30% favela energy is stolen
- • Frequent power cuts and blackouts
- • Limited clinics within favelas
- • Long waits at public hospitals
- • Gang violence prevents ambulance access
- • Schools overcrowded with poor facilities
- • High dropout rates - children work instead
- • Drug gangs recruit young people
- • Drug trafficking gangs control some favelas
- • Police violence: 1,000+ deaths/year in Rio
- • Residents caught between gangs and police
Economic Challenges
Unemployment & Informal Work
- • 20%+ unemployment in favelas
- • Most work in informal sector (street vendors, cleaners)
- • Low wages, no job security, no benefits
- • Formal jobs inaccessible (lack education, discrimination)
Extreme Inequality
- • Wealth gap visually stark
- • Rocinha (poverty) overlooks South Zone (luxury)
- • Same city, vastly different life chances
- • Inequality reinforces social divisions
Environmental Challenges
- • No formal collection in many favelas
- • Waste accumulates in streets and hillsides
- • Pollutes streams, attracts rats and disease
- • 2+ million vehicles cause emissions
- • Industrial pollution from oil refineries
- • Particulate matter exceeds WHO safe levels
- • 55% of Rio sewage is untreated
- • Guanabara Bay heavily polluted
- • Fish death, health risk, beach closures
- • Rush hour speed: 5 km/h (walking pace)
- • Inadequate public transport
- • Air pollution + time wasted + economic loss
