We have examined the evolution of nature management systems in a historical context. An analysis has been made of the crisis of existing nature management models, an aggravation of contradictions, and an increase in threats and risks at the beginning of the 21st century. Modern trends in the development of effective nature management have been discussed, namely, low-waste technologies, technoecopolises, agroecopolises, and green clusterization. We have generalized and suggested conceptual prospects in the realm of effective nature management: the concept of a New Ecological Policy and a new “ecopolicy of containment.” We have explored the possibility of introducing the culture of nature management contributing to reinforcing the necessary rules and regulations—the binding force of the system of restrictions and prohibitions for humans in nature management, with due regard for the sustainability of natural systems. Emphasis is placed on a crucial need for changes in mass-scale consumer stereotypes and for an increase in the number of green technologies and production and the furthering of ecological education and medical–ecological tourism, as well as the importance of reorientation of the attitudes of the population from ecological–consumer to social–spiritual values in accordance with the Code of the Culture of Nature Management. We have substantiated the need for integrating the economic determinism of nature management and the ecological–economic imperative of sustainable development based on a noospheric approach.

The aims of our researches is to identify priority directions of the world's cities emerging from the post-Сovid crisis based on an assessment of the Russian cities environment quality before the COVID-19 pandemic. The analysis of the Russian cities ecological sustainability by the beginning of the pandemic COVID-19, component-by-component and complex assessment of quality of the Russian cities environment are done. The urgent need of the existing urboecodiagnostics system changes is explained. Directions of its efficiency and of the objectivity increasing are indicated. The needs of priority steps of development and organization for the post-Сovid cities recovery after the socio-ecological crisis are justified. We resumed that there is an objective problem in integrated assessment of the urban environment quality. The novelty is: it is shown that the only integral, systemic vision of natural, anthropogenic and urban processes, the latest technologies can become the drivers of sustainable urban development.
