Assessment of the level of environmental safety of regions based on fuzzy indicators

Waste generation leads to an ever-increasing technosphere load on the environment, representing one of the main threats to the environmental safety of territories, sustainable development of urban districts and regions. This contributes to an increase in risks and threats to a favorable and comfortable living environment of the population.The fundamental vector of the research is the formation of scientific approaches, methods, indicators of achieving the state of protection of the natural environment from the anthropogenic impact of waste, while providing favorable conditions for human existence in the technosphere in the form of a part of the biosphere transformed by society. The purpose of the study is to develop a fuzzy scale of indicators for assessing systems, facilities, life support technologies of technosphere territories at the stage of development of pre-project and project documentation. In accordance with this goal, within the framework of using the theory of fuzzy sets and the corresponding mathematical apparatus of soft computing, a fuzzy scale of levels of resource and environmental indicators was developed for the implementation of predictive studies of the long-term development of life support systems of settlements at the pre-project stage, during the implementation of project activities, when assessing the current level of technosphere impact of hazardous waste on the environment. The proposed new approach, based on a comprehensive assessment of the prevented environmental hazard, was used in the formation of a forecast for the development of waste treatment and disposal enterprises for the period up to 2030 in the regions of Russia. It seems possible to use environmental safety indicators and methods of their determination when creating criteria for sustainable development of territories, target indicators of technosphere safety of objects, systems for integrated assessment of safe and comfortable living environment in settlements.
