The article examines the systems of adaptive forest management in the Republika Srpska (Bosnia and Herzegovina) and forest-steppe and steppe regions of the Central Black Earth region of Russia (within the Voronezh region) in the context of climate change, suggests measures for adaptive forest management. The concept of adaptive measures can be useful to rationalize and focus existing views on adaptation and restoration of forests. This area is designed to help reforestation, with particular attention to the ability of ecosystems to self-organize in the future and adapt to changing environmental conditions. adaptive capacity It is imperative to consider new or unparalleled ecosystems to ensure the best mix of ecosystem services in the face of future uncertainties. substantiation of improving models of forestry in the context of climate change and ensuring their practical implementation. Directions for further research in this area should relate to the development of risk-based planning approaches and multi-stakeholder decision-making.

Proposals on organizational and economic mechanisms of staged transition to the basin system of water resources/water use management that is to provide practical implementation of the “basin principle” and self-financing of water sector of economy.

For the ecology of the big city it is very important to have such a significant woodland, as, for example, natural and artificial plantings of Prof. BM Kozo-Polyansky Botanical Garden, Voronezh State University. The article briefly characterizes the botanical garden, its origins and the present conditions. The main goal of the definition of forest pathology and health status of all the stand has been put on one of the key areas of the botanical garden referred to as "Northern ravine oak wood." In conducting research we use standard methods of forest inventory and forest pathology examination with appropriate post-processing. The detailed data on the composition, taxation rates and conditions of the studied plants are given. Complete loss of the composition of exotic species planted in 30-x – 70-ies of the last century is revealed and we determine an accelerated death of English oak and European white birch, which is actively being replaced by Norway maple and Scotch elm. Comparative analyzes of forestpathological characteristics of the main forest-forming species of this area is made, and conclusions about the lack of competitiveness of such artificially planted exotic species as the horse chestnut, bitternut walnut and European larch in natural groves stands is drawn. A list of found external characteristics of each species diseases in the surveyed forest stand is given. On English oak leading pathological features are: shrinkage of the skeletal branches and inboard hollows. On the Norway maple there are also a lot of dead skeletal branches, and a lot of trees with pathological forms of the barrel. The main conclusion of the work lies in the fact that the stock data on shrunken and especially drying trees testify to the strong weakening of the stand. Conducting sanitary measures in the form of selective sanitary cutting is required for its recovery.

We have considered results of the recent investigations aimed at development of scientific/methodical base for water resources value assessment within the framework of academic support of the “Federal plan of statistical works” realization. Indicators of the water resources value assessment will enable to solve a number of problems of state management of the water/economic complex: to perfect the mechanism for water resources accounting in the system of national accounts; to secure the water resources balanced use; to develop more rational system of charges for water use; to support adoption of the water-saving regime; and to perfect the mechanism of identification for water resources depletion. Methodic approach to the water resources value assessment is differentiated depending on the direction of the assessment results use. Necessity and adequacy of the income assessment method recommended by SNS-2008 was determined for purposes of national accounting at the current stage of the natural/resources component statistic accounting system development. A method of total (integrated) assessment of the water bodies resources potential economic value assessment has been proposed. Promising perspective directions of investigation in this sphere have been considered.

The main goal of modern forestry today is development and improvement of management methods that can combine economic sustainability, biodiversity conservation and the ability of forest ecosystems to adapt to continuous environmental changes. The significance of global problems leads to increased interest in the study of the functioning of complex natural ecosystems. Forest ecosystems are characterized by high structural heterogeneity, which is important in collecting reliable information. In the current critical situation with an increase in the concentration of carbon dioxide in the atmosphere, the study of the environment-forming functions of forests is of paramount importance
