To what extent can urban areas be sustainable?
Sustainability refers to meeting the needs of current and future generations, whilst preserving the environment for future generations, also without compromising the future needs and plans. Recently the management of transport has been increasingly needed due to the increasing amount of ownerships, for example, since 1950; there are 30 million more cars on UK roads, and the increasing awareness of greenhouse gas emissions which contribute to climate change.
Over the past 30 years the world’s population has grown rapidly, also leading to rapid urban growth as people move in from the surrounding rural areas for better jobs, better quality of life and a wider variety of resources. However, by this taking place there has been a huge increase in transport congestion, as seen on 16th of February 1980. Due to poor weather and the huge numbers of cars on the French Auto route, the jam spread from Lyon to Paris, it stretched 109 miles. This is highly unsustainable as stationary cars, increase chances on photochemical smog’s, such that in London a smog event occurred in December, 1952 when five days of calm foggy weather created a toxic atmosphere that claimed about 4000 human lives.
Curitiba grew rapidly in the second half of the twentieth century (from 150,000 people in the 1950’s to almost 1.6 million today). This rapid growth caused mass unemployment, transport congestion, lack of basic services and the growth of squatter settlements. A redesigning of the city put about by Jamie Lerner. In terms of transport, Curitiba now has 5 arterial roads that run east to west and development along these has been encouraged, diverting traffic away from the city centre, making it more pedestrian friendly. Also the old noisy and polluting buses have been replaced with cleaner, more efficient versions. This increases health standards and safety for future generations, therefore making it sustainable. There has also been consideration for...
