million from the Rio government for the first stage, an
identical budget was given for the second phase in 2000

- the residents choose the changes that they want
to make to their communities and are used for
the labour so they learn skills and want to keep
their work intact so dont break it and deface it
- has improved life for thousands of people
- they cant use good materials so some infrastructure
must be repaired soon after construction
- the workers are not very educated so in one case made the road
higher than houses so the water runs into houses instead of down the
road
