Renewal is the action and the result of renewing (leave something like new, return it to its original state, replace something old with something new, restore what was interrupted). Urban , meanwhile, is what is associated with a city (an agglomeration of buildings and inhabitants that functions as an administrative unit and whose economy is based on non-agricultural activities).
It is known as urban renewal to the initiative or the process you are looking for modify infrastructure and constructions of a city . This type of entrepreneurship is carried out when the city in question becomes ancient and can no longer cope with the current demands of the population.
Urban renovation can include the removal of old buildings and the construction of new ones, or the remodeling and restoration of existing buildings. Suppose that in a town of low houses there is a noticeable housing deficit due to the increase in population. To alleviate this problem, the authorities decide to develop an urban renovation and begin to build large towers so that people have access to the living place .
The creation of green spaces It can also be part of urban renewal. In a neighborhood where dozens of skyscrapers have been built in the last decade, squares and parks may be needed to improve the quality of the environment and to offer neighbors recreation spaces.
The creation of new streets, the widening of avenues and the installation of luminaires are other decisions that can be part of a draft of urban renewal.
The urban renewal dates from the early days of the industrial city , which arose as a result of the industrial revolution and was characterized, in part, by the increase in its population, the appearance of public transport means, the extension of the city through roads communication , the replacement of the old walls by the boulevards and, not least, the creation of the elevator, which allowed the construction of taller buildings.
A large part of the middle western cities went through some kind of sanitation or rehabilitation work of its working class neighborhoods throughout the 19th century, and in all cases one of the most important points was the decision to demolish the walls . On the other hand, communication axes were also opened and the streets widened to give rise to wide avenues that would facilitate the transit of pedestrians and carriages.
The scope of urban renewal should not be underestimated, reducing it to a mere washing of the face of a city focused on aesthetic issues. On the contrary, this complex operation that began a few centuries ago was part of well-defined strategies that pointed to the revaluation of entire neighborhoods and resulted in a economic activation and to various aspects of social development .
At present, urban renewal usually takes place in urban centers, since it is there that the oldest and least prepared neighborhoods are located to meet the social and economic demands of the times. It is important to note that the budget Necessary for such an action is considerable and that the investment does not always recover.
A phenomenon that must be taken into account by the public administration when dedicating its efforts to urban renewal is the "contagion effect", which describes the ambivalence of two neighboring real estate properties in terms of their value : if one remains in perfect condition but the other deteriorates, the latter negatively affects the first, while if both are maintained they benefit each other.
