“…The solution of the ODE system makes it possible to justify the ability of ecosystems to withstand external influences [24,[32][33][34]. Discrete models allow similar problems to be solved using the theory of random processes in the form of MCs or AIPs [15,16,19,[24][25][26][27][28][29][30][31].…”

“…Characterized by having complex internal interactions and a large number of elements, arid pasture ecosystems are difficult to study by traditional methods. In this regard, the forecast of the occurrence of productivity decline risks, the occurrence of land degradation, and desertification quantification requires the use of various mathematical modeling methods [9][10][11][15][16][17][18][19][20][21]. One of the leading issues here is the problem of sustainability, since only stable ecosystems that can withstand certain anthropogenic loads and climate change can exist and function stably [9,15,[21][22][23][24].…”

The problems of the sustainability of arid pasture ecosystems are solved by mathematical modeling, which relates the issues of rational exploitation of the natural environment, the limits of its pollution, the permissibility of environmental management, and reclamation measures.…”

In this study, the issue of the ecological stability of the soil and vegetation cover of the North-Western Near-Caspian arid zones within the borders of the Black Lands (BL) of the Republic of Kalmykia was considered. Modeling was carried out of the open systems’ thermodynamics principles using continuous and discrete formalisms. Models presented in the form of systems of ordinary differential equations, Markov’s circuits, and autonomous impulse processes show the possibility of their application in the management of pasture feed stocks. Modeling with the systems of differential equations makes it possible to identify points of stable states of pasture systems. Markov circuits are able to establish an optimal animal load on these systems. A computational algorithm for determining the stability of pasture ecosystems using autonomous impulse processes allows optimization problems to be solved to determine the conditions for the spread of external influences. Computational experiments were carried out to determine the parameters of the model corresponding to the sustainable mode of operation in arid pasture ecosystems.

Experience in application and adaptation of the land degradation neutrality concept in the Russian Federation

et al. 2022

The paper provides an overview of the-evolving methodology for the land degradation neutrality (LDN) assessment based on studies at national, regional, and local levels in Russia. A review of more than one hundred publications in Russian language over the past 6-7 years allowed for analysis of the following areas: LDN terminology, LDN assessment at different levels, adapting a transition matrix; using the LDN concept for economic valuation of land, estimating LDN baseline, and using LDN as an integral indicator for sustainable land management. With the LDN concept, a global approach to monitoring land degradation has become applicable beyond the limited geographic scope of the drylands. The paper observes how the LDN concept has been broadened with the introduction of the LDN Index proposed to evaluate the rate of LDN achievement; a proposal on reconstructing transition matrices and adding land cover sub-categories; approach of integrating traditional national sectoral systems for assessing land quality with an LDN add-on. The broader relevance of the paper includes the justification that it provides for using the LDN concept by policy-makers at national and subnational levels, in particular in Russian-speaking countries. It includes the application of additional indicators to capture soil erosion, salinity, soil depletion, aridity, etc., and using different sitespecific LDN baselines, not only those time-based but also factoring natural background trends like climate change, natural succession cycles linked with geological and geomorphological processes. Approaches for LDN-based economic valuation of lands and typology of sustainable land management practices and models were also fruitful.
