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

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.

The aim of the research is to assess the current state of steppe ecosystems, which are subjected to human impact and to provide scientifically‐based proposals for the conservation and regeneration of their natural potential.The object of the study is the steppe ecosystems of the arid zone in the Stavropol Territory. The research conducted in 2019–2021 included the use of methods and techniques, encompassing the geobotanical, economic and statistical, abstract and logical, computational and constructive.An analysis of the natural resource potential of the steppes in the arid zone of Stavropol Territory showed a discrepancy between the current livestock and the carrying capacity of this territory. The forage for grazing is about 830 thousand tons of feed units, which is 1.5 times lower than the livestock needs. The predominant plant associations are wormwoodbluegrass‐sedge, bluegrass‐sheep fescue‐wormwood, bluegrass‐feather grass‐wormwood, bluegrass‐ wormwood‐salt grass with low species diversity – from 10 to 17 species per 100 m2. The plant cover of the soil is from 30 to 60 %, which indicates its sparseness. The average biological yield of phytomass is 7.0 kg/ha of air‐dry matter. The species diversity of the steppe communities is represented by weed species that have low forage quality. In natural phytocenoses, the cereals dominant in forming cenoses in virgin land, have been lost. There are no any representatives of the legume family in the plant stand.The scientific approach to sustainable development, conservation and regeneration of the potential of natural ecosystems in agricultural landscapes involves the rational use and improvement (rehabilitation) of the remaining low‐yield natural grass stands that have lost the ability of regeneration.

In this work, the main goal was to analyse the erosional hazards within the boundaries of the Kalaus River catchment area.The paper analyses the erosive state of the region's lands, for which industry and cadastral maps, a digital elevation model and satellite images were used. Official data of ministries and departments were used. Geographic information systems – QGIS and SAGA GIS – served as the basis for modelling. The article presents the results of GIS modeling of erosional hazards in the territory of the Kalaus River basin. Based on the (DEM) SRTM digital elevation model, the basic morphometric indicators of the relief were calculated: steepness of the slopes and vertical and horizontal dissection of the relief. Based on morphometric indicators, an integral calculation of the energy of relief and erosion hazard was carried out and a series of relevant thematic maps was created. The values of slope steepness obtained within the boundaries of the basin range from 0° to 51° with average values of 2.5°. The horizontal dissection varies in the range from 0 to 0.84 km/km2, and the erosion bases are characterized by a range of values from – 15.0 to 248.6 m, with an average value of 33.0 m. The formation of the erosional potential of the basin’s relief is facilitated by the location of a significant part of the region on the spurs of the Stavropol Upland, which have widely developed slopes. Based on the calculated raster of the integral energy index of the relief, 3 categories of erosional hazard are identified. Most of the basin of the Kalaus River (58.4 %) is characterised by a low erosion hazard, another 39.0 % of the territory presents an average erosion hazard, and the remaining 2.9 % belongs to territories with a strong erosion hazard. The classification of relief surface shapes based on the Iwahashi and Pike method, which was carried out on the basis of a DEM, shows a much greater prevalence of steep slopes with high convexity in the southern part of the Kalaus River basin.The identified features of the level of erosional hazard of the lands of the Kalaus River basin are recommended to be taken into account in preinvestment, pre‐design and urban project planning of the territories of administrative units located within the boundaries of the basin. Despite the fact that the results of GIS analysis cannot completely replace field erosion surveys, their value as a tool for planning rational land use is obvious. The results of the work can be used to carry out a similar assessment in other regions, primarily in the organisation of agricultural production.
