The authorities supplied materials to residents to build their own permanent accommodation in Rocinha (such as cement, breeze blocks).

- Now an urbanized neighbourhood

- Almost all houses are built with brick and concrete today

- Supplied with electricity and basic sanitation facilities.

world-class events ahead?NO

What should Rio do?Is Rio ready for the two world-class events ahead?

How can Rio be competent for the two games ahead?

Beijing

1. Rapid expansion of railroad

1. Rapid expansion of railroad

Cleaner

Increased accessibility for poor people

Wealthy people takes airplanes or cars

A Shipyard in Rio, showing water pollutants

2. Subsidies for polluting industries (for purchasing eco-

friendly equipments and better filtering systems)

Creates incentives to cut water pollution

Improves global image of Brazil

Expand public transport systems, with renewable/ eco-friendly sources

Roads

BusRailway

Airports

Develop rural areas/ commuter

zones

Despite Rio de Janeiro had a low city air pollution, Brazil contributed to 1.3% of global emissions. Therefore, Brazil should also help tackle global warming, and Rio is the perfect place to start with this.

“

Why Rio is a good place to develop renewable power sources:

-Abundant rivers and rainfall (for HEP)

-Coastal Area (for wind power and tide power)

-Good accessibility

Tourist hub: Better global image

But...

Money can never solve all of the problems.

Besides infrastructures, what can we do?

Or problems will never have existed.

2.Constitutional Reforms

Regulated Urban Land

-Urban land use zoning-Better regulations and restrictions to development

-Halt illegal settlement development

-Inspections to ensure infrastructure safety

Land Tenure Redistribution

1% PEOPLE

OWNS 47% LAND

Creates incentives for poor peasants to shift out of cities

“The Marvelous City”

Brazil had a chance for shining it’s soft power to the globe through Rio, but certainly it requires a good planning... and money.
