Abstract:
Due to the fact that urbanisation, as a domintating global development process, has been reached a dramatic measure, series of questions have been arisen about its environmental impacts. The urbanisation, as a incresing process which its fastness has been provided by unprecedented population growth, let to a series of consequences such as inconcivable and unbalanced consumption of natural resorces and global warming rate accelleration. In such a dramatic circumstances, how can urban planners and authorities contribute to climate mitigation and emission reduction? How should one manage urban vulnerability and enhance urban resilience? How urban morphology is correlated with urban sustainability? And how urban transformation should be propled in order to address this challanges. The correlation between urban development and environmental stewardship is crystal clear. Subsequently, how should one implement practical methods to tackle urban growth and environmental issues simultaneously is the main headline. How should integrate urbanisation and the issue of saving natural resources? How can design strategies contribute to climate mitigation and emission reduction? Is the urban morphology correlated with these issues? And eventually, how can the urban transformation be performed, retrofitted and monitored in order to achieve a more sustainable result? A strictly sectorial approach could result in neglecting mutual dependencies of these demands. Conversely, an integrated approach can help to sharpen a better comprehension of the different performances of different urban assessment.
IMM, Integrated Modification Methodology, is a multi-stage, iterative process, applied to urban complex systems, for improving the metabolism of the city as well as its energy performance. The method has been depicted through prior publications by the authors; hence, the current paper solely focuses on one stage of the multi-stage IMM method. Due to the facts that most future growth in urban areas will occur in developing countries and its relative few megacities, where will live 5{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} of earth population, the study wish to present a case study of megacity of Rio de Janeiro.
Despite the GDP growth by roughly 50 percent in real terms over the last decade about 20 per cent of the city’s population lives in informal settlements known as Favelas. These slum areas have very limited access to public services and amenities. Electricity distribution is perhaps an exception, but often informally accessed. Alike great number of cities around the world; the city of Rio is experiencing preponderance growth in its margin which has been amplified since 1950s. More accurately, the municipality of Rio de Janeiro has added 3.9 million residents since then; while the suburbs and exurbs have added 4.8 million. The authors intended to examine how a local design area located in the dense core of Rio (Porto Maravilha) can affect transformation of the entire CAS (the city of Rio de Janeiro) toward more sustainable development some city’s main concerns, mitigating marginal growth, low performances and a growing pollution as promoting social inclusion and a more livable environment.
