The article considers the concept of the circular economy as an important tool for achieving sustainable development, which relates to the preservation of renewable resources’ mass through the renewal of withdrawn resources and the restoration of disturbed ones. It is directly linked to remedial land treatment in post-mining disturbed land. However, after numerous studies, the conceptual apparatus of recultivation remains unspecified. Moreover, there is a gap regarding the trends of evolutionary changes in studies of legislation and feasibility on the subject of recultivation. Employing comparative law as a tool, the aim of the study is to develop a consistent approach based on circular economy by establishing the stages of legal support for recultivation and identifying the content of all these stages regarding economic efficiency. Currently, the environmental priorities of the economy are triggering the usage of the ecosystem approach for assessing the ecological result of recultivation. Therefore, the core of the paper is the development of a consistent circular economy approach by (1) clarifying the concept of recultivation, (2) identifying the stages of the development of a legal framework for recultivation and (3) revealing evolutionary changes in feasibility studies on recultivation. The authors prove that recultivation should be considered from the perspective of geoaesthetics, which implies a harmonious incorporation of the recultivated landscape into the environment.

This article considers the concept of natural capital as a basic construct of sustainable development. However, after numerous studies, a number of aspects of accounting and valuation of natural capital remain unspecified. The relevance and imperfection of the guidelines used to assess natural capital make relevant the development of such issues as the conceptual apparatus and methods to natural capital assessment. Therefore, the core objectives of the paper are: (1) to substantiate the structure of natural capital, taking into account the natural resources and ecosystem approaches; (2) to clarify the concepts of “function” and “services” in relation to abiotic and biotic components of the environment; (3) to generalize and analyze the classifications of ecosystem services, and to develop the authors’ classification; (4) to identify the most common methods for the economic assessment of natural capital’s components, and to implement these methods within a specific territory. These methods have been tested on the Khanty–Mansi Autonomous Okrug (KhMAD, Russia). The most typical ecosystems of the region and their inherent ecosystem services have been identified. Assessment results are presented for (1) forest ecosystems, (2) mountain ecosystems, and (3) ecosystems of swamps, lakes, and rivers.
