Urban regeneration is the rehabilitation of land areas that are subject to high-density urban land use. It is a strategy that aims to transform and renovate areas to be upgraded in housing, public and private buildings, infrastructure, and services. This entire process is an effective way to improve urban performance by targeting areas with high rates of poverty, pollution, and congestion, leading to a complete economic and regional development of the area. Urban regeneration programs are only proven successful when sustained.
As a result of its successes, urban regeneration is now known as the attempt to reverse declining cities. It does so by improving physical structures through new urbanization models and methods and by working to enhance the economy of those cities. These new urbanization models and methods must be highly enduring systems that prove sustainability, which is reached by covering all aspects of the four interconnected domains which include ecology, economics, politics, and culture.
Today, the process of urbanization continues to generate many problems deriving from the constant migration of more populations towards already highly populated cities. Resolving these issues is possible by turning them into efficient habitats, saving resources in a way that improves the standard of living. The process, however, faces a number of major challenges related to reducing pollution, improving main transportation and infrastructure systems. New urban solutions are required to optimize the use of space and energy resources leading to improvements in the environment, i.e. reduction in air, water, and soil pollution as well as efficient ways to deal with waste generation. These challenges contribute to the development of social and economic disproportions and require the development of new solutions.
The level of difficulty of managing such problems with found solutions in several cities differs from one city to the other depending on several variables which mainly include the size of said cities. However, despite such complexity, they offer a generative ground for architects, engineers, city planners, social and political scientists, and other professionals the ability to conceive new ideas and time them according to technological advances and human requirements.
