Environmental Planning In Rio De Janeiro Environmental Sciences Essay

Few metropoliss in the universe are good popular. Few of metropoliss have undergone major alterations in the modern epoch and really small is known about such metropoliss and one such metropolis being found in South America. Rio de Janeiro is the capital metropolis of the province of Rio de Janeiro, the 2nd largest metropolis in Brazil and is normally referred as Rio. The resources built up during the earlier periods guarantee that it would lend a major portion for future developments.

Rio is located along Brazil ‘s Atlantic seashore, where the shoreline is oriented east-west. The halfway part of Rio normally referred to as North zone is composed of deposits and several rocky and hilly mountains. The South zone of the metropolis opens to the sea is fragmented from the centre by mountains. The big West zone has a cragged terrain. Hence the metropolis ‘s uneven topography required a careful planning coupled with dearly-won technology. ( Roy Gilbert, 1988 )


Despite the rapid growing experienced by the metropolis in the nineteenth century, it was merely in early 1900s that the population reached 0.8 million compared to today where the population is around 6,345,758. Its pristine urban environment began to degrade taking to the eruptions of xanthous febrility all over the metropolis. Thus the necessity to better the town planning grew from a wellness position. The metropolis ‘s uneven topography had made them to trust on sophisticated technology. The execution of Pereira Passos program in 1906 itself required them to the devastation of an full hill including Rio Branco Avenue. Later the Agache program was proposed in 1927, which helped to continue the memorials and incorporate the waterfront in to the urban metropolis. However the same program was non implemented, but it did assist to better the subsequent town planning. Thus the planning had a late entry in to the metropolis of Rio. Subsequently in 1982 the metropolitan development program of Rio got officially approved as a policy model by the authorities governments. ( Roy Gilbert, 1988 )

Turning population, dining economic system and inefficient conveyance systems had led to a batch of jobs. Most of the jobs in Rio were related to its topography which had been the job in planning of the metropolis in the yesteryear. Apart from these jobs, Rio is confronting other jobs like edifice of houses on inclines due to the topography of the land and this has besides led to jobs like dirt eroding, landslides, etc as shown in figure 1.

The inefficient planning of early yearss has led to a batch of wretchednesss in the present. Some of them include the proper location of industries, deficiency of industrial development policies, and absence of sites for the disposal of increasing domestic and industrial waste. In malice of traffic direction schemes the roads are filled with a million Numberss of private autos which has forced the Government to look out for alternate manners of transit like belowground tube rail systems which are expensive as good. The subsequent programs in 1977 for the metropolis of Rio were a mere failure due to the deficiency of fundss. The programs were emphasized on supplying conveyance and conveyance corridors in order to manage the asphyxiation on roads despite traffic direction systems. ( Rou Gilbert, 1995 )

Taking in to account of the above reference factors bing in the metropolis, a determination was made to redesign the program of the metropolis wholly by continuing certain environmental parts and besides continuing the heritage centres as a portion of their urban planning policy. ( Zeca Brendao, 2006 )


The Government of Rio pursued some cardinal urban revival schemes to better the planning over the last 7 old ages to better the planning of the metropolis. These schemes saw significant alteration in the development of Rio. The engagement of civil society in undertaking readying and execution stage helped to advance urban consolidation which was however smaller when compared to Porto Alegre which empowered public engagement in bordering public policy for the metropolis. It was so that a metropolis broad Favela upgrading, make overing on the strategic program of the metropolis and the Rio Cidade was proposed. These were the metropolis broad alterations that were made to manufacture the urban expression of the metropolis. ( Claudio Acioly Jr, 2000 )


The strategic program of Rio adopted some of the schemes adopted by Barcelona in their strategic planning. In the urban revival scheme the commercial centres located in the vicinities were considered which are important for the local image of the metropolis of Rio. Studies were made to analyse the scenario in the metropolis. There were both environmental devastation and economic diminution. This led to a ill managed urban environment, unequal substructure, and hapless public walkers. Hence plans were addressed to screen out these jobs. In tie up with local and foreign designers the Favela were upgraded and more people were given lodging. Public engagement in be aftering led to a sense of ownership among the citizens which helped them to be after the metropolis better. The strategic program besides focused in the mobilisation of resources in order to better the research and development, substructure and natural environment assets. Like other European metropoliss Rio de Janeiro launched many plans so as to better architecture, resuscitating the lodging in the downtown countries and waterfront development so as to better the quality and image of the metropolis. ( Claudio Acioly Jr, 2000 )

An of import urban design scheme adopted by Rio as mentioned above is the preservation of heritage centres in the business district parts which is besides known as the Corredor Cultural ( Cultural Corridor ) . History reveals that there has been a alteration in values and ideas. They have been stressing on the cultural and urban preservation and rehabilitation. Until the early 1990 ‘s the zoning of metropolis was applied on the full graduated table of land, its so merely in ulterior ages that three local programs were proposed to conserve Sao Cristavo from development. Four events have taken topographic point in the yesteryear which has led to colonies in Sao Cristavo. These include:

Ejection of Jesuits

Arrival of settler

Port extensions

The unveiling of Avenida Brasil

Hence in order to conserve they valued the heritage memorials for their historical and artistic value and tried continuing them by act uponing these values in the national policies. ( Zeca Brendao, 2005 )


The urban structural undertakings or the PEU helped to advance heritage centres. The program PEU 2004 helps to rehabilitate the urban infinite by advancing residential countries in bing storage sheds. The valorization of cultural heritage helped to excite the economic activities and touristry.

Figure 2: Comparative limits of 1986 and 1993 saving countries ( Beginning: Andrea da Rosa Sampaio, 2007 )

The figure above shows the limits of the old ages demoing the saving of heritage centres in the metropolis. It can besides be seen from the program that the limitation of residential and industrial utilizations in the country helps us to understand the zoning that has taken topographic point over the clip to better the program of the metropolis. ( Andrea da Rosa Sampaio, 2007 )


The tube rail system opened in Rio in 1979. However when it was started it covered a distance of 4.3km and linking five topographic points in the business district country which are by and large non accessible by the hapless people. Then stairss were taken in their program to cut down the private manners of transit and promote more public conveyance. The pie chart below helps to demo manners of transit adopted by people in 1975. ( Bruno Luis de Carvalho district attorney Costa et al, 2010 )

Figure 3: manners of transit adopted by people in 1975 ( Beginning: Bruno Luis de Carvalho district attorney Costa et al, 2010 )

After the appraisal of population that the determination to build a metro rail at Rio was decide which would cover all parts of the metropolis so as to transpose by cut downing the load on the common roads and do all topographic points easy accessible due to the topography of the metropolis. The figure below shows the tube rail that is scheduled to open in 2010 in Rio. ( Bruno Luis de Carvalho district attorney Costa et al, 2010 )

A big figure of metropoliss are built along rivers and watercourse. These H2O organic structures have been the major beginning of colony around the part. Merely in the recent old ages that high importance is been given to the relation between H2O organic structures, metropoliss and population be it in the academic degree or at the planning degree. Since the early eighteenth century the major focal point has ever been related to urban rivers to screen out drainage issues. The map below shows the metropolitan part of Rio where the urban rivers are found. ( Lucia Maria S.A. Costa et Al, 2010 )

Rio from an environmental position has a figure of rivers, lagunas, canals and fens. The metropolis is farther dominated by three scopes viz. Tijuca, Pedra Branca and Gericino. It besides accounts for the largest urban wood in the universe. The map below shows the environmental exposure of Rio. ( Helia Nacif Xavier et Al, 2003 )

From the information available sing be aftering most of the land has been used for developments. The tabular array helps to exemplify the land usage bing as of 1996.

Occupational activities have been carried near the watercourse and river Bankss, have highlighted the fact that though parts have been under legal protection and they remain vulnerable as shown in figure 4. These colony activities have led to environmental debasement.

Recently a figure of river direction plans have been carried out to continue the environment from farther debasement. This has been achieved by including these Restoration activities in their planning which has nevertheless happened quiet late since the development of the metropolis. Some of the worth mentioning programs are as follows ( Lucia Maria S.A. Costa et Al, 2010 ) :

The proposal for the revival of the Bananal Stream which is located near Sao Paulo. This was rehabilitated by intercession of landscape undertakings along the Bankss of the rivers.

Another undertaking is the Restoration of Cabucu de Baixo River through similar landscape intercessions which covered wider facets like hydrology, biological science and ecology which was all aimed towards cut downing deposit and dirt eroding near the Bankss of the river.

Another recent program which helped to reconstruct the environment was in 1994. Baixada Alive plan was set to incorporate a diverse set of actions by taking in to account the presence of boroughs that make up the metropolis part. This plan aimed at get marrieding societal and urban installations for a sustainable urban environment. This plan was barely achieved and the low quality constructions led to the death of the plan.

Apart from these river direction programs, really small involvement is shown with regard to bio diverseness. South America is known for its rich biodiversity and hosts some of the rarest species on the planet. The disconnected Mata Atlantica has been enduring a batch of jobs due to big scale colonies that have taken topographic point over the old ages in Rio. The land usage intensification has led to negative impacts on the ecosystems of Mata Atlantica. Sustainable land direction is a large job for Mata Atlantica. The loss of biodiversity and natural resource debasement will go on in Rio if proper steps have non been taken to undertake these jobs at the planning degree.


The general loss of religion in physical planning is the chief ground for Governments in many metropoliss to pretermit urban planning. Rio has besides undergone similar failures as mentioned in this assignment. Though the programs have been framed every bit early as 1900 ‘s really few have found its manner in successful execution. The diminution of urban planning in the metropolis of Rio is quiet unusual as there had been some success in the initial phases. Some of the late framed urban policies have been making justness in the development of Rio by assisting to pave manner for more public and unfastened infinites. Even today the incorporation of public infinites in to urban planning has been the cardinal characteristic of Rio de Janeiro.

The engagement of environment in to the metropolis ‘s planning procedure had taken some old ages to be implemented owing to the fact that in a underdeveloped metropolis like Rio more focal point was towards the people. In the close hereafter land usage direction would be a large job for Rio. This would necessitate necessary actions to be taken to run into the conflicting demands of the metropolis and pull off the land resource without compromising on the facet of sustainability. Controling land debasement provides benefits to the metropolis at the planetary degree. These include the preservation and saving of bio diverseness, stairss to cut down clime alteration and spring to turn to the millenary development ends for human development. ( Hartmut Gaese et Al )

Despite some of the success in be aftering plans in Rio, jobs associating the environment, transit, land usage, sewage system can non be resolved at the local degree entirely. This would necessitate the co ordination of province authorities and the municipalities to work together to turn to these jobs and supply a sustainable solution. These jobs have to be sorted in the close hereafter to guarantee that Rio occupies a strong place among the planetary metropoliss in the approaching century.
