Improving Slum housing

• Areas of slum housing built from waste

materials are called ‘shanty towns.’

• Slums are illegal, i.e. they are built on

land that they do not own.

Improving Slum housing

• Millions of slum dwellers need improved urban conditions.

• Often help comes from NGO’S (e.g. Oxfam) working inslums alongside funding from local authorities.

• Scale of slums now makes it impossible to supply largeengineering projects through these areas e.g. sewagesystems.

• Slum improvement focuses on;

1. Right of ownership for residents. Renewed confidenceto improve home.

2. Providing basic services (e.g. schools and clinics)

3. NGO’s (e.g. Water Aid) improving the water supply (e.g.tube wells)

4. Residents improving their own sewers, roads, etc.through ‘aided self help’ scheme, which providetraining and building materials.

Improving health and environment

• Improving water supply and sanitation are crucial if

the cycle of poverty and deprivation is to be broken.

Some water supply projects cost billions and take

decades to complete.

• Often requires external aid owing to the extent of the

problem.

• Small-scale water and sanitation projects are often

implemented by NGOs.
