The purpose of the article is to substantiate scientific approaches to streamlining methods for assessing the state of ecosystem assets of territorial communities related to water, from the standpoint of sustainable nature management on an ecosystem basis. The modern scientific developments on estimation of cost of ecosystem services connected with water, are resulted in the leading international documents are investigated. The peculiarities of application of the methodological approach of ZEC (general economic value) are revealed, which provides taking into account both the real characteristics of the actual use of ecosystem services related to water and the potential (hidden) characteristics of their non-use. It is determined that the most promising in the process of assessing ecosystem services related to water may be the use of methods such as: "market" prices; normative; cost transfer; benefit transfer, scenario development method, subjective assessments. It is emphasized that these methods can be applied both separately and in certain combinations (combinatorics), due to the need to take into account the specifics of ecosystem services produced by ecosystem assets and the impact of integration processes within the ecosystem interaction of territorial spatial formations. In this context, the possibility of applying the concept of ZEC to assess ecosystem services related to water, on the example of the village of Semenivka Blagodatnensky united territorial community of Pervomaisky district of Mykolayiv region according to the author's methodology and formalized them using several methods. Further research has prospects in the following areas: formation of a comprehensive system approach to streamlining the methods of cost measurement of water-related ecosystem assets; development and introduction of effective methodological approaches to the assessment of ecosystem assets, which are based on the use of combinatorics of possible assessment methods, which are selected in accordance with the characteristics of the local territorial water resource potential.

The state of Tamil Nadu, India, is in the grips of a water crisis, with demand far outstripping supply. As the economy of the state grows, this crisis is going to become ever more serious. To date the focus of state water policy has been on trying to augment supplies, from within the state (even from desalinization) and from neighboring states. In addition, the water use is regulated in a way that does not encourage the highest value uses. International experience shows that supply-side measures must be complemented by demand-side measures and that practice must move away from fixed, command-and-control allocation policies towards flexible allocation mechanisms, which facilitate the voluntary movement of water from low to high-value uses. This study addresses the question of whether such a change in allocation policies is worth doing. It addresses this question by developing optimization models for each of the 17 river basins in Tamil Nadu (including an assessment of the economic value of water in different end-uses – agriculture, domestic and industry), then using an input–output model embedded in a social accounting matrix (SAM), to assess the impact of these changes on the state economy and on different rural and urban employment groups. The results suggest that a shift to a flexible water allocation system would bring major environmental, economic and social benefits to the state. Compared with the current “fixed sectoral allocation” policy, a flexible allocation policy would, in 2020, result in 15% less overall water used; 24% less water pumped from aquifers; 20% higher state income; with all strata, rich and poor, benefiting similarly, with one important exception, that of agricultural laborers.

Central Chernozem is one of the largest agricultural regions in Russia. As a result of the long period of natural resources use the anthropogenic load on agricultural lands is increasing. The result of agricultural nature management is the increase of land degradation processes. Voronezh Region has a high agro-climatic potential, most of the territory is occupied by agricultural land, arable land prevails among them. Soil degradation is the most acute problem. There is a need to assess the impact of agricultural natural resources use on land resources of the region. Modular coefficients for assessment of geochemical impact of agriculture and animal husbandry on agricultural systems are proposed. The developed factor is a tool for identification of negative land use processes and environmental problems. The article deals with the issues of ecologically oriented, scientifically grounded strategy of agricultural nature management. Ecological approach to assessment of soil quality in the future will develop a strategy for balanced land use. The article has a scientific and practical character and is aimed at the development of methods of ecological assessment of soil quality. The proposed methodological approach identifies destructive processes in soils. For ecologically oriented strategy of development of regions it is important to define maximum allowable agricultural loads for preservation of sustainable environment.

Forest ecosystems are an important anthropogenic pillar to human wellbeing, providing a multitude of ecosystem services. In Mediterranean countries, where climate change effects are exponentially increasing, the value of the forest ecosystem services is even higher and their preservation is more crucial. However, the biophysical and economic value of such services is usually not observable due to their non-marketable characteristics, leading to their underestimation by decision-makers. This paper aims to guide decision-making through a set of new management scenarios based on ecosystem services’ values and their spatial distribution. It is a cumulative multidisciplinary study based on biophysical models results, economically valued and implemented using the geographic information system (GIS) to analyze spatial data. The investigation was based on a biophysical and economic valuation of cork, grazing, carbon sequestration and sediment retention as a selection of ecosystem services provided by cork oak forest (Ain Snoussi, Tunisia). The valuation was made for the actual situation and two management scenarios (density decrease and afforestation of the shrub land), with emphasis on their spatial distribution as a basis to new management. The total economic value (TEV) of the investigated services provided by Ain Snoussi forest (3787 ha) was €0.55 million/year corresponding to €194/ha/year. The assessment of two different scenarios based on the land cover changes showed that the afforestation scenario provided the highest TEV with €0.68 million/year and an average of €217/ha, while the density decrease scenario provided €0.54 million/year and an average of €191/ha. Such results may orient decision-makers about the impact new management may have, however they should be applied with caution and wariness due to the importance of the spatial dimension in this study.

Forest ecosystem services (FES) are considered as public or common goods facing diverging individual and societal interests affecting the quality of ecosystems and well-being of the communities. This may result in overuse, degradation or unsustainable behaviour, as well as it can create also barriers for cooperation, economic profit and innovative business initiatives. The paper introduces the methodological approach which is applied within six different innovation regions (conceptualised as social-ecological systems) within the InnoForESt H2020 project. Each region uses innovative approaches in governance of FES and payments schemes. They are situated in Austria, the Czechia and Slovakia, Finland, Germany, Italy and Finland. All are characterised by manifold, sometimes diverging, FES, such as timber, recreation, regulation services or education. In order to get a better understanding of the role and the impact of key innovation factors for the regions, we have designed a behavioural [lab] experiment in the form of a Role board game (RBG). The proposed experimental game builds on Cardenas et al. (2013) and Castillo et al. (2011) as an interactive agent-based model arranging for repeated interaction and learning in real-world situations. It contributes to testing the effectiveness of incentives provision for the sustainable production of FES and the acceptance of such an intervention by FES communities (Kluvankova et al., in press). The game enables the adaptation to the specifics of each innovation region but at the same time it keeps the same internal experimental mechanism which will enable the comparison across the regions. The main question to be addressed by the RBG is: How to create conditions to enable innovations in forest management/governance for sustainable use and well-being in innovation regions under the diverging interest of FES users? We plan to test combinations of key innovation factors as preferred future scenario for sustainable FES provisions in regions, including fundamental policy interventions (e.g. strict regulation vs. payments for ecosystem services scheme), business incentives and external risk factors. RBG will allow testing stakeholders’ specific behaviour for resource use, and innovation activities, to create economic incentive, knowledge and social value. We argue that this will help to set conditions for successful development of policy and business innovations in innovations regions and to foster collaboration on FES provision for sustainability among stakeholders in a long term.

The research area—the Kolkhety National park (Georgia)—is situated in the western part of the Kholhida lowland and includes coastal waters of the Black Sea. It was established in 1998, but its economic value was not assessed. The purpose of the work was to identify the ecosystem services of the park’s geosystems, to carry out an ecological-economic assessment of part of the ecosystem services, and to create map of ecological-economic assessment, which is necessary for its nature management regulation, including its buffer zones, as well as nature conservation and recreation activities. Using our field data and thematic publications we compiled a map, presenting 4 large areas of ecosystems: the Kolkhida woodlands, wetlands, the lake Paleostomi, the Black Sea water area. 25 ecosystem services were identified within them. The following were among them: resource ecosystem services—provision of feed for cattle, commercial products of water bodies, etc.; regulating—creation of the coastal line, wetlands water filtration, etc.; supporting—carbon deposition by terrestrial and aquatic ecosystems; information—recreation services. Information data base was compiled for several of them and used for assessments based on the widely used international methods. The assessment result of only seven ecosystem services demonstrated their cost—10.5 mln dollars annually. The results of ecological-economic assessments were used for compiling of an ecological-economic map presenting spatial distribution of different ecosystems services costs. The results may be used for the Georgian coastal area territorial planning and demonstrate the economic value of nature protected lands.

The article presents the essence and main points of the methodological approach to the substantiation of the optimal combat staff of the armed forces from the perspective of the theory of prevented damage of our troops in the operation and taking into account military-economic capabilities of the state, in particular, financial constraints on the procurement and maintenance of combat means of relevant j-types. Inconsistency between tasks scope, which are entrusted to the armed forces (AF) for national security, and level of their combat capability has been and remain one of the fundamental problems that adversely affects the process of their forming, developing, preparing and using. That kind of inconsistency is caused by the impact of some factors, primarily factors characterizing economic-military capabilities of the state. Such factors also involve the capacities of the defense industrial complex in terms of development, production, modernization and providing military units (MU) with weapons and defense equipment (WME). The experience of the troops shows that current financial constraints on the procurement and maintenance of the necessary WME negatively affect the level of MU fighting potential. Thus, the problem and need for the substantiation of optimal combat staff of the AF have been and remain inherent components of the process of their forming and developing taking into account military-economic capabilities of the state. The above defines the relevance of the research under consideration and needs new scientific approaches to the justification of optimal combat staff of the AF, which would ensure guaranteed execution of national security tasks. Based on the analysis of recent research and publications related to the problems of substantiation of the AF staff as well as the assessment of the impact of CP of MU on the level of their combat capability, the paper establishes that available methodologies (methodological approaches) don’t specify some issues, including what should the optimal AF combat staff be for guaranteed execution of their intended targets, taking into account the military-economic potential of the state? One of the alternate solutions of the problem is the methodological approach, which is presented in the article, to the justification of the optimal combat staff of the armed forces from the perspective of the theory of prevented damage of our troops in the operation and taking into account military-economic capabilities of the state, in particular, financial constraints on the procurement and maintenance of fighting means of relevant j-types. To get a much better sense of the essence and content of the research subject, the authors define a range of the concepts: “military-economic factors”, “prevented damage”, “prevented damage theory”, “combat potential”, “combat capability”, “combat staff”, “effectiveness of combat use of forces”. The authors believe that compared to the available methodological approaches (methods), the methodological approach set out in the article allows: formalizing the interrelation between the level of combat capability of our forces and the desired value of their prevented damage (CP maintenance) for a defined period of operation, which is achieved by the results of counteraction (fire effect) of fighting means of j-types of our troops against the enemy. This enables us to determine the number of combat means of all j-types of our troops required at the initiation of the operation, which (taking into account losses for T days of combat activities) ensures the target level of their fighting efficiency; carrying out the differentiated approach to the determination of the role (contribution) of every kind of our forces in the execution of tasks set in the operation that makes it possible: to calculate the contribution of every j-type of combat means (military branch) to the tasks of general damages on enemy and achievement of combat actions of the required correlation of parties’ CP during T days; to define the contribution of combat means of every j- types (military branch) to reducing the predicted value of the average-daily costs of the original CP of our troops to the acceptable one, the accomplishment of the necessary absolute value of our troops and maintenance of the target level of their combat capability during the T-days operation; improving (based on the indicators of prevented damage) the mathematical model of the optimization problem and elements of the calculation process (algorithm) that allows studying the interdependence between core indicators, which evaluate the effectiveness of combat use of troops during the operation, more specifically. Prospects for future research are the detailed elaboration of mathematical models and elements of the calculation process (algorithm) for upgrading methodical apparatus, which makes it possible to substantiate the optimal combat staff of the AF required for the successful execution of state security tasks from the perspective of the theory of prevented damage of our troops and taking into account military-economic capabilities of the state.

Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional security. Using a pollinator (honeybee) exclusion approach, we evaluated the impact of pollinator scarcity on production in four brassica fields, two producing hybrid seeds and two producing open-pollinated ones. There was a clear reduction in seed yield as pollination rates declined. Open-pollinated crops produced significantly higher yields than did the hybrid ones at all pollination rates. The hybrid crops required at least 0.50 of background pollination rates to achieve maximum yield, whereas in open-pollinated crops, 0.25 pollination rates were necessary for maximum yield. The total estimated economic value of pollination services provided by honeybees to the agricultural industry in New Zealand is NZD $1.96 billion annually. This study indicates that loss of pollination services can result in significant declines in production and have serious implications for the market economy in New Zealand. Depending on the extent of honeybee population decline, and assuming that results in declining pollination services, the estimated economic loss to New Zealand agriculture could be in the range of NZD $295–728 million annually.

The search for a balance between nature conservation and sustainable development remains a scientific and spatial planning challenge. In social-ecological systems based on traditional rural activities and associated with protected areas, this balance is particularly complex. Quantifying the economic impact of land use changes on ecosystem services can be useful to advise policy makers and improving social-ecological sustainability. In this study, we evaluated the land use changes in a time series and estimated the monetary value of the ecosystem services of the Urdaibai Biosphere Reserve (Biscay, Spain). In addition, we linked the monetary and biophysical values of land uses in each zoning units of the reserve, in order to identify the spatial adjustment between both assessments. Results showed that land use changes have clearly homogenized the landscape without substantially affecting its economic value. The methodological approach allowed detection that the reserve zoning was performed based more on its biophysical values than on economic ones. Thus, evident divergences between the biophysical and economic assessments were found. The core area was the one that had the highest coincidences (medium values) between both ecosystem services assessments, which highlights its importance not only in biophysical terms, is also economical. The procedure followed proved to be a useful tool to social-ecological planning and design of specific conservation strategies for the sustainable development of the area.

Goal. The goal of the article is to substantiate the theoretical and applied aspects of economic security complex assessment on the example of regional business structures with the use of the apparatus of mathematical modeling in Economics in modern conditions of business macro trends. The assessment of the state of economic security of enterprises is carried out through a system of criteria and indicators. The criterion of enterprises economic security is a measure of the state of the entity in terms of compliance with the established indicators of its activity with pre-established indicators reflecting the essence of economic security. On the basis of this goal, the question arises of solving such problems as: the possibility of developing a unified conceptual approach and tools for assessing the impact of indicators on the of regional business structures’s economic security; developing measures to improve the economic component of regional business structures. Research methods. Structural methods, comparative analysis of empirical data, abstract-logical generalization and mathematical modeling in Economics were applied to solve this scientific problem. Results. In the work on the basis of the methodological approach the model of assessment formation of the enterprise’s economic security has been grounded on the basis of impact of economic security indicators by means of logit and probit-functions. The model does not take into account group effects, that is, there is no analysis of fixed effects. In order to avoid cross-effects, when not only the variable itself influences the likelihood of a crisis, but the public crisis begins to affect the behavior of the variable, two groups of models are built: for the first group of regressions from the sample, all observations after the first year of crises are excluded; for the second group of regressions all data were used except for the crisis years after the first year of the crisis. Conclusions. The fundamental provisions of the scientific investigation will enable domestic regional enterprises to apply the algorithm of forming the economic security assessment of the enterprise using the apparatus of mathematical modeling in Economics.
