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.
