The management of green space businesses is critically important for the development of the country, as it has positive effects on the environment, the efficient use of limited natural resources, and the reduction of global warming. It also helps prevent the greenhouse effect and improves the overall environment of the country, thus enhancing the quality of life for its citizens. Therefore, integrating various fields of knowledge, including economics, society, and the environment, to apply them to the management of green spaces in urban areas is of paramount importance. This approach will contribute to the sustainability of green space management in the future.
