Delineation of especially valuable agricultural lands (EVAL) is currently an important task, which will make it possible to preserve agricultural land for its direct use. There are currently no uniform approaches for delineation of EVAL, or they need to be upgraded. We have proposed a new approach based on GIS modeling and simulation of agricultural plant growth. It is proposed to delineate EVAL for each municipal district taking into account its existing specialization in agricultural production. The allocation of EVAL should be based on the assessment of potential productivity of soils and lands for cultivation of the main crops in the district. EVAL should also include pilot fields and areas used for scientific and educational purposes, regardless of potential soil productivity. The proposed approach has been successfully tested on the example of Yasnogorsk district of Tula region. It is shown that the EVAL map, based on the proposed approach, is more related to the actual land productivity and does not depend on the current land use within the area. It is possible to build an EVAL map for the whole country only by building such maps separately for all municipal districts of Russia.

Effects Of Land Use

The study analyzes the possibilities of using cost estimates of ecosystem services to assess the effects of transformations in land use. The consequences of transformations were assessed by comparing the value of basic ecosystem services for different patterns of the land use structure, taking into account the fact that the volume of ecosystem services provided is limited by the ecosystem sustainability limits. To estimate ecosystem services, the methodology developed by the author was used. It is based on the indicators of agricultural land productivity and their value terms. The assessment was carried out for the Zarinsky district of Altai Krai, located at the junction of the West Siberian and Altai-Sayan physicogeographical countries. The study has revealed that the greatest value of basic ecosystem services in the region with agricultural specialization can be achieved by optimizing the agricultural load – reducing the share of arable land and increasing the share of forage land in the total area. It is proposed to implement this by involving plots of fallow lands in circulation: some of the plots are proposed to be used for reforestation, while others – for haying and grazing. This will balance the need to maximize agricultural production, while not reducing the sustainability of the ecosystems.

Abstract Experimental studies on the effectiveness of the use of new organo-mineral amendments obtained on the basis of biocompost to restore fertility and increase the productivity of degraded alluvial meadow medium loamy and sod-podzolic sandy loamy soils of reclaimed agricultural lands were carried out by the authors of the paper as part of the implementation of the state assignment of the Ministry of Science and Higher Education of the Russian Federation “To develop a scientific and methodological approach and new agro-meliorative methods for restoring the fertility of degraded reclaimed lands, reclaiming contaminated soils and disturbed pasture areas in the European part of Russia”. The studies included a series of long-term greenhouse and field experiments performed on the reclaimed lands of JSC “Moskovskoye” and the stationary site of the Meshchersky branch of the A.N. Kostyakov All-Russian Research Institute of Hydraulic Engineering and Land Reclamation, which resulted in new ways of restoring the fertility of degraded reclaimed agricultural land and low-productivity lands involved in agricultural circulation using multifunctional amendments for the conditions of the southern part of the Non-Black Earth Zone of Russia. At the end of the experimental studies, the authors developed a database, and then an information and reference Web-system that allows entering, storing, finding and analyzing information on ways to increase the soil fertility of degraded reclaimed agricultural land and low-productivity lands involved in agricultural circulation using biocompost based on the processing of organic waste. This software allows making scientifically based and timely decisions to restore fertility and increase soil productivity.

Drone technology is becoming more and more popular in our lives. Drone technology; industry, art, agricultural production, and many other areas are heavily used. With the system called Agricultural Unmanned Aerial Vehicle (DRONE), at least 10 percent efficiency is expected to be achieved every year in agricultural land. In practice, agricultural lands are examined and the places where intervention is needed for soil health are determined. With the multispectral camera on it, the appearance of the land is examined and a soil map is taken and it is determined that the area of 100 hectares is photographed in 30 minutes. As a result, soil structure is analyzed, chlorophyll map is created, plant health is examined and weeds are detected. Irrigation is also checked for difficulty. After the work, it is ensured that the producer can benefit from the soil in the most efficient way. In this study, you will be informed about the types of drone types used for agricultural purposes, whether you need to register a drone owner's vehicle, selected applications and what you can see in the images. with the help of a detailed literature, those experienced in different countries and in particular for agriculture to be evaluated will be determined case for Turkey.

The analysis of the current Classification of types of intended purposes of land use is carried out. It is established that the existing 2-level Classification does not meet the modern requirements for monitoring land relations and the norms of current land legislation. The structure and content of the 4-level Classifier of typesof intended purposes of land use are proposed, which allows to determine in detail the type of permitted land use. It is established that the current classifier does not distinguish between the form of management and the type of land use. This issue is especially evident in the example of agricultural land, in which case the types of intended purposes indicate the legal form of landowner or user, rather than regulating the direct use of land. The proposed 4-level classifier is able to distinguish between the form of management and the type of land use. In forming this Classifier, the principles of complexity, systematicity, exhaustiveness, hierarchy and legality are taken into account; requirements of automated technologies for maintaining the State Land Cadastre and remote methods of land monitoring are considered, comprehensive and systematic methodological approaches in compliance with current domestic land legislation and relevant bylawsare applied; principles of openness and manufacturability, as well as recommendations of international organizationsare taken into account.

Occurrence Of Species

Agroecosystems have traditionally been considered incompatible with biological conservation goals, and often been excluded from spatial conservation prioritization strategies. The consequences for the representativeness of identified priority areas have been little explored. Here, we evaluate these for biodiversity and carbon storage representation when agricultural land areas are excluded from a spatial prioritization strategy for South America. Comparing different prioritization approaches, we also assess how the spatial overlap of priority areas changes. The exclusion of agricultural lands was detrimental to biodiversity representation, indicating that priority areas for agricultural production overlap with areas of relatively high occurrence of species. By contrast, exclusion of agricultural lands benefits representation of carbon storage within priority areas, as lands of high value for agriculture and carbon storage overlap little. When agricultural lands were included and equally weighted with biodiversity and carbon storage, a balanced representation resulted. Our findings suggest that with appropriate management, South American agroecosystems can significantly contribute to biodiversity conservation.

Productivity Indicators

<p>A study was performed to assess the trends of productivity on land with different land quality to derive land performance indicators.  “Performance” of the productivity in this context means the local productivity in a given period as compared to the range of productivity levels measured from land units with similar properties within the whole are of the assessment (Ivits and Cherlet 2016, Sims 2017). Land quality is indicated by the potential productivity of agricultural land in Hungary. In this study we used actual biomass productivity indicators based on EEA (2020) and land productivity indicators based on Tóth et al (2018). The Plant Phenology Index (PPI) as proposed by Jin and Eklundh (2014) was used to define trends in actual productivity of terrestrial vegetation for the whole agricultural land of Hungary. The 100 m resolution national spatial dataset of land productivity (Tóth et al. 2018) is based biophysical land properties, ie. soil, terrain and climatic properties. The study covered the whole grassland and cropland areas of Hungary and concerned the period of 17 years between 2000 and 2016, inclusive. The procedure to identify performance, which takes biophysical land quality information into account corresponds to the Good Practice Guidelines of CSIRO/UNCCD (Sims et al. 2017). The land quality (land capability) map was used to assess the Performance of land units in comparison to the potential of lands with similar properties. </p><p>Our study reveals that declining vegetation production is equally experienced in all capability classes of croplands, affecting 0.7-2% of the land areas of the capability classes, marginal, average, good and very good. On the other hand increased production is seen in higher shares of marginal land (15% of marginal croplands and 14% of marginal grasslands) and on that of average capability (9,5% and 17.7% in croplands and grasslands respectively), while increasing productivity is limited to 2,6-6,1% of good quality land. This significant difference between the areal extent of low and high quality land where productivity increase is measured suggest that differences in natural fertility of soil is offset by improving climatic conditions. Management factors may play less important role, as forest and grassland areas – which are less intensively managed in Hungary – show a general trend of increasing productivity in around 20 % of their total area too. Increasing productivity is less widespread on more productive land, which can be explained by the favourable soil properties including good water management, which can secure high production also in years with less precipitation. Similar argumentation can hold also for good quality grasslands.</p><p>The current study, taking also a soil-based indicator into account is a step to a direction for including meaningful biophysical indicators to degradation assessment.</p><p>The study was conducted by the Institute of Soil Sciences of the Agricultural Research Centre in the frame of service contract with the Hungarian Ministry of Agriculture.</p>

The non-black earth zone of Russia is a zone of guaranteed harvest of major agricultural crops. However, at present, the potential of the reclaimed lands of the Non-Black Earth Region remains largely unrealized. In world agricultural practice, land reclamation combined with the use of modern technical means is an important factor in the development of agriculture, a condition for a consistently high level of agricultural production. Therefore, in all countries, reclaimed lands are given a special status, and the necessary amount of reclamation fund of agricultural lands is created.

Points Of View

In  densely populated areas, such as Flanders, serious conflicts arise due to the  afforestation of agricultural lands. Roughly speaking, three sectors are  involved: agriculture, forestry and nature conservation. These groups do not  always share the same points of view. But even within the different sectors  there are several subgroups with their own interests and approaches.  Generally speaking, agriculture is strongly opposed, forestry has a  relatively diversified meaning, whereas nature conservation is either opposed  or in favour, depending on the region's biological value.     The policy in this matter is not forest friendly. Legislation strongly  hampers the afforestation of agricultural lands. Moreover the subject leads  to a series of ecological problems, which have not really been considered up  to now.
