Improvement schemes: Top-down approaches
1. Top-down schemes are expensive large-scale plans, usually by the government, aimed to improving squatter settlements
2. A $2 billion development project aims to rehouse slum dwellers in high-rise apartment blocks built next to the slum
3. This is controversial as it will break the sense of community to the settlement
Improvement schemes: Bottom-up approaches
1. Bottom-up schemes are cheaper and smaller plans usually by the community and NGOs to improve squatter settlements by helping the individual
2. Self-help schemes give people the tools and training to improve their homes
