There are a number of factors that contribute to wild urbanization. One of the most common is rapid population growth together with the lack of space. As populations increase, more people need places to live, and this can lead to the rapid construction of new housing, often without proper planning or consideration of the environmental impact.
Another cause of wild urbanization is economic development. As economies grow, people move to cities in search of jobs and opportunities. This can lead to a rapid increase in the demand for housing and infrastructure, which can be difficult to meet.
Government policies can also contribute to wild urbanization. In some cases, governments may lack the resources or the political will to properly plan and manage urban growth. This can lead to a situation where cities grow without any clear direction or purpose.
