A multi-factor model as the basis for the environmental quality management of urban аreas

E. V. Sokolskaya, B. I. Kochurov, Yu. A. Dolgov, V. A. Lobkovsky
Section: Research methods. Models and projects
The article considers mathematical approach to environmental quality management to improve the ecological comfort of living for the population. The problem of environmental management is described using a multi-factor model of quality of the environment with the weight coefficients of the importance of its components: atmospheric air, acoustic impact, soil, water resources, and green spaces, accessibility of natural and recreational areas. The values of weight coefficients of importance of influencing factors for environmentally comfortable living are determined by the method of expert assessment. A multi-factor model is used for detailed assessment of the ecological quality of the urban environment. The proposed quantitative approach also allows to compare the environmental comfort of the different residential districts or to study the dynamics of environmental comfort of specific urban area. Much attention is paid to scientific and methodological principles of management and the formation of the concept of «environmental quality». The strategy of environmental management with ecological foundation of various practical solution is shown. The plan of measures on organization of optimal management of quality of the environment to improve comfort of living for the population of the residential microdistrict of Tiraspol is presented. Graphical scheme of the results of integral analysis of various environmental indicators and assessments for improving the comfort of the environment is given. Realization of environmental quality management of the urban areas on the basis of a multi-factor model contributes to the gradual change of dangerous ecological conditions of environmental factors, to increase a comfort of the territory taking into account the real preferences and needs of the population.

Analysis of Kramer’s coral-reef food web model

M. Solomonovich, I. Bica, L. Gao, А. Hailu
Section: Research methods. Models and projects
The model of a coral reef ecosystem, proposed by D.B. Kramer and published in Ecology and Society in 2008, explored the implications of changes in biological parameters and changes in economic and social interaction variables governing the fishing behaviour of anglers targeting the two fish species included in the model, herbivore and piscivore fish. This model is parametrized based on evidence provided in the literature. The recognition of multiple species in the model as well as the inclusion of adaptive harvesting behaviour may supposedly allow to explore policy or management options. This paper reviews, extends and sharpens the analysis undertaken in original article, and reveals both mathematical and interpretational mistakes in it. We use analytical and numerical methods to show that, contrary to the assertion in discussed article, some of the equilibrium outcomes are independent of the parameter values that were identified as important in this paper. At the same time the model is highly sensitive to the setting of some parameter values as well as to the structures representing interactions in the model. We suggest ways in which the model can be modified so that it would become interpretable.

Genetic engineering in solving “unsolvable” problems of soil remediation

A. A. Gulevich, E. N. Baranova, I. G. Shirokikh, A. A. Shirokikh
Section: Theoretical problems of ecology
Many centuries of cultivation of plants allowed human civilization to significantly increase the population of the planet. However, as a result of economic activity, many areas have turned into waterless deserts, salt heaths, dumps and waste pits that remain after mining. Classical technology has been developed for many decades, but this has not led to an effective solution of the problems that have arisen, and humanistic values do not allow for the reduction of the population. In this review, new approaches are considered that can significantly improve the efficiency of remediation. The solution involves combining biotechnologies: genetic engineering of plants, fungi and microorganisms; in the compartment with the application of nanotechnology recultivation and creation of artificial analogues of soil and new materials of geoplastics for the creation of an artificial landscape. The principal possibility of creation of plant complexes and microbes-rescuers on the basis of potentially resistant organisms capable of effective interaction is considered. The review deals with the genetic modification of plant and bacterial organisms that allow to accelerate in principle the formation of biogenic matter on disturbed and remediated soils, including man-made soils. This can restore the ecology of the abandoned lands destroyed by mankind over the centuries of its existence.
Keywords: soil degradation, waste pollution, ecobiotechnology, phytoremediation, rhizosphere microorganisms, genetic engineering, landscape reconstruction
