The problem of constructing field pipelines from the oilfield to the main pipeline or an oil loading terminal is considered. Cost estimates for routes of field pipelines take into account the pipeline construction and operation costs, environmental accident pollution risks, compensations to local residents, and costs of compensatory projects to accommodate local interests. This helps to ensure that conflicts are avoided in the process of economic development of northern territories. A specific feature in evaluating the total costs is the use of fuzzy numbers. The authors' adaptation of the Shimbel-Otterman method is substantiated for choosing an optimum field pipeline route, whose adaptation involves the application of fuzzy cost estimates for individual segment options of the pipeline route. The proposed approach to the analysis of the resulting solution relies on the use of a confidence level function, which helps the decision-maker to identify the most viable field pipeline route option. A detailed algorithm for solving the problem is laid out, with a numerical example to prove the operational quality of the proposed method.

Damage from environmental pollution (damage from violation of environmental legislation) is a basic category in environmental-economic research and is assessed during the development of project documentation, environmental audit, evaluation assessment of the effectiveness of investment projects, environmental risks insurance. At the same time, variety of existing assessment approaches necessitates methodological and methods’ streamlining in the field under consideration. The purpose of the study is to review and systematize national and foreign experience in assessing damage from environmental pollution. Research methods: ecological-economic analysis, content analysis, information modeling, statistical analysis. The key findings of the study: identification of contradictions in the field of understanding and assessment of environmental pollution damage category, streamlining of methodological principles and methodology support in the field under consideration, development of approaches’ classification for calculating damage from pollution depending on the methods used and the directions of assessment, systematization of methodology support based on a wide range of criteria. Scope: environmental audit and expertise, environmental insurance, as well as regulatory documents of ministries (Ministry of natural resources, Ministry of ecology) and departments (Rostechnadzor, Rosvodresursy, etc.), scientific and educational publications on the assessment of anthropogenic load.

The subject of the research is conflicts between businesses and local population concerning negative impact of mineral resources extraction on the environment and possibilities of its prevention. The purpose of the work is creating an economic mechanism for  ecological conflicts prevention in the regions where mineral resources are extracted through implementing an economic mathematical model of forming optimal assortment of compensatory measures. Mechanisms of preventing ecological conflicts in mineral resources extracting regions including two ingredients — expert analytical and optimizational — are proposed. While realizing the expert analytical constituent of the mechanism, local population on a par with authorities and representatives of the extracting enterprise are involved in prioritizing in the course of reducing man-impact on the environment and in the process of compensatory measures portfolio forming. Optimizational constituent of the mechanism for ecological conflicts prevention demands forming a model for optimal compensatory measures choice. Scientific novelty and significance of the work are presented by a rate scale for expertise of possible negative ecological consequences of creating and operating an extracting enterprise from the point of view of population groups. As the research result an algorithm of expert assessment processing enabling to determine the priority ranking for reducing man-impact on the environment and tension reduction between the extracting enterprise and local population is formed. An optimizational model enabling to determine optimal set of compensatory measures taking into account the interests of both extracting enterprises and the most conflict groups of local population is proposed.

The extraction of natural resources in the mining regions causes environmental pollution, changes the landscape, and reduces biodiversity, and leads to conflicts between the local population and the mining enterprises. The paper aims to design a methodological tool for eliminating social tensions in the mining regions during field development and exploitation. The goal can be achieved by creating compensation projects that take into account the priorities assessed by the stakeholders: the population, the regional authorities and the mining enterprise. As the compensation projects strive to solve social and environmental problems in the mining regions, they include the direct financial compensation to the population, development of traditional enterprisers, reduction of environmental pollution, infrastructure development, etc. We focused on two logically connected tasks: 1) assessing the significance of compensation projects and funding by the regional budget and the mining enterprise; 2) determining the sequencing of the considered projects. For solving the first task, we proposed a method of the multi-criteria significance assessment of program projects from the perspective of the population, the regional authorities and the mining enterprise, based on a specific unified rating scale. This method uses a technique that cuts off options with low interest in the projects. Thus, it allows assessing the significance of the program projects, as well as calculating the shares of funding by the mining enterprise and the regional budget. For solving the second task, we applied the economic and mathematical model and the heuristic method, determining which projects should be implemented first. The experimental calculations showed that the developed compensation programs comply with the preferences of the stakeholders. The application of the developed approach can contribute to the balanced socio-economic development of the mining regions in conditions of intensive field development and exploitation.
