1. Sustainable urban environments Praag Dogra
2. Curitiba - Brazil 2 million inhabitants 1000km from Rio de Janeiro Heavy and manufacturing industries Lacks slums, congestion an pollution Principle architect: Jamie Lerner (Governor of city) – believes in small scale bottom-up strategies. Backing of citizens is critical for change of rural environment The city has been transformed from an agricultural centre to a manufacturing powerhouse The planners visit the city to view the best practice
3. Waste management They are ahead of their time – first in the world to start recycling in the late 1980’s Recycling crews wear identifiable green overalls Organic and inorganic waste is separated by the residents which is separated by the crews on different trucks The UN awarded Curitiba with its highest environmental prize Enough recycled material has been collected to fill several thousand skyscrapers Recycled building plant built from recycled material- paper, plastics, and cans are sorted for off-site processing, Costs are similar to landfill 2/3 waste is recycled, which is one of the highest rates on the planet It creates jobs- provides migrants and disabled with work
4. Planning and housing The ‘solution of the parks’ – green spaces and lakes planned into the heart of the city Solved flooding by turning river banks into parks and trees are planted plentifully Disused factories turned into sports facilities to prevent squatters from settling there Excess water during the rainy season is diverted into the lakes Skyscraper developers were allowed permission to add a couple of floors to their development in exchange for Planting green spaces at the bottom of the skyscraper Or providing finance for low income housing
5. Transport sustainability Curitiba has an integrated transport system There were 5 main transport arteries created in the city The centres of the wide roads were converted to bus lanes and then there were colour coded buses which interchange stations. Red busses: express bus with few stops Orange busses: link suburbs with bus routes Green busses: link the inner city to express routes No subway was built because it is too expensive and takes too long Volvo locally manufactured busses which were greener and cheaper than standard busses. It carries the same amount of people that the metro does in Rio de Janeiro The tubular bus stops increase the speed and efficiency of boarding the busses The fares not collected by the drivers increases boarding speed This doubles the number of busses travelling every day
6. Low income residents There is a large pool of well educated workforce and has one of the oldest universities in Brazil- attracting overseas investment Social charter places emphasis on helping the low income earners There is a ‘green exchange’ (created in 1990) when there was agricultural overproduction in the green belt. Rather than throwing away food, it was traded with the low income residents’ recyclable goods for food or bus tickets The cities garbage trucks cannot fit down the narrow shack lanes – surplus food not wasted and expensive road widening is not necessary 300 tonnes of recyclable waste is collected every month
7. Shopping centre regeneration Created a mall in the heart of the city to make it a vibrant, pedestrianised central business district Lerner wanted to complete the regeneration in only 48 hours so no lawsuits could be filed, and in the end it was done in 72 hours Military government of the time enabled the opposition to be stifled This revolutionised the area, children bought into the area deterred vehicles by painting whilst the parents shopped Also, this created a pedestrianised ‘family-feel’ atmosphere encouraging trade.
