In this study, parallel to the literature, according to the findings, it can be said that the global population growth and the exponential increase of this population in the cities cause a rapid decrease in natural land and vegetation areas, and a rapid increase in irregular, unplanned and unplanned urban areas. Partially, the seriousness of the issue is not considered by the national and local politicians who direct the growth of cities, and illegal constructions that cause environmentally harmful practices are increasing around the world. On the other hand, the issue not considered at all by informal interest groups active in illegal settlements and economy. Urban transformation and the improvement and transformation of slum areas are generally considered in terms of the socioeconomic well-being of the communities, this primary task is sometimes overlooked by policy makers and economic concerns are prioritized, but in both cases, sustainability and the protection of the natural environment, which should be the highest goal, can be contradicted from time to time. The aim of this study is to develop suggestions for eliminating such negativities. Suggestions developed for the correction of negative examples were created by applying the principles of management systems to the subjects. Along with negative examples, developed, newly developed and developing countries also offer some positive examples of reducing carbon emissions in urban areas and urban development and urban transformation practices that are in harmony with nature and respectful to nature. Thus, positive and negative examples were analyzed and interpreted, and suggestions based on the principles of management systems were tried to be developed.
