Land use change and a shift in economic activity often bring to unpredictable consequences for local ecosystems. There is a necessity of making preliminary evaluation and analysis of comparing the different types of economic and ecological transformation, including cost and benefit analysis, not only for business and local population, but for the whole environment. We give an example of a particular animal husbandry farm in Karelia and show how potential change in economic specialization can be effective on a 10 years horizon. Among other land use types, we chose peat mining and wetland conservation. Each type of activities was complexly evaluated with different types of costs and benefits. In the paper, we use a method of land use change evaluation including the value of ecosystem services. The monetary values of ecosystem services are given with the respect to foreign analogues and taking into account local realities and prices. Our results have shown that the most beneficial for the society and the environment is wetland conservation, due to their berries picking service, which are highly appreciated on the market, and due to low costs for the third parties, since wetlands contain regulative and refinery services for local ecosystems. As a contrary peat mining is a profitable business, but pollutes the environment because of carbon emissions into the atmosphere. The current specialization for animal husbandry is neither an optimal solution because of low profitability of the chosen farm. The results of the research can be used for optimization in regional politics in the sphere of agriculture and environment economics in order to protect the ecological balance between human activities and nature. ; Дан анализ возможной смены землепользования и хозяйственной деятельности одного из хозяйств Пряжинского национального района Республики Карелии.

The purpose of the study was to assess the current state of food security in some regions of the Russian Federation, to identify bottlenecks that hinder its achievement, and also to try to determine the relationship between food security indicators and the degree of land degradation - categories that largely determine the socio-ecological development of the region. Belgorod, Vladimir, Volgograd, Kaliningrad, Penza, Samara regions were selected as test regions. At the same time, the choice of the self-sufficiency indicator for the main types of food products as the most representative indicator for assessing food security at the municipal level is justifed. The adapted methodology for calculating self-sufficiency for the municipal level consisted in using the calculated indicators of the required production volumes in accordance with rational consumption standards, which allowed us to obtain an objective assessment of how much municipal formations are able to provide the population living there with the main types of products. The adapted methodology proposed by the authors for calculating indicators of self-sufficiency in basic types of food at the municipal level is described in detail in earlier publications. The results of the analysis of the data obtained on self-sufficiency in such types of products as potatoes, vegetables, meat, milk, fruits and berries in the municipal districts of the test regions in dynamics for the period 2010-2021 are presented. In addition, the relationship between the calculated indicators of self-sufficiency in the main types of food and the degree of land degradation in the municipalities of the test regions was revealed. The results obtained made it possible to identify the main problems associated with ensuring food security and develop proposals to improve the situation.
