Land Reallotment over the Course of the Development of a Rural Settlement in Ukraine

Abstract: The study is dedicated to land reallotment in the course of land use alteration in Ukraine. The case of the development of an individual residential block in an agricultural area is considered. The issue of the alteration of the spatial characteristics of land plots and changes in their designated use have been highlighted. The objective of the article is the substantiation of land reallotment at the level of an individual residential block on agricultural land which is privately owned by a number of landowners. The preconditions for the development of land reallotment in a rural‑type settlement in the suburban area of a big city have been substantiated. Alternative approaches to land reallotment have been suggested. A comparative analysis of the suggested approaches and their practical approbation have been carried out. The change of land plot spatial characteristics in the course of reallotment by means of various reallotment scenarios has been analysed. Land plot value after reallotment in each scenario has been specified. The practicability of each approach depending on the initial conditions has been substantiated. The research can be used in the course of rural settlement development planning, the coordination of measures on land use type alteration with landowners and land users, with private landowners or the implementation of local community initiatives.

Land Consolidation Considering Natural Afforestation

Abstract: The article highlights the problem of natural agricultural-land afforestation with insufficient forest cover of the area. The article purports to substantiate land consolidation aimed at the rationalisation of agricultural and forest land management in such conditions. The authors identify the main approaches to the issue of natural agricultural land afforestation. The afforested areas of agricultural land are suggested for redesignation as a forest resource as a result of a swap and reallotment of land plots. As an example, consolidation of available land, in the conditions of natural afforestation, has been accomplished based on a number of land masses in Chernihiv Oblast’, Ukraine. Resulting from the project implementation, better configuration and improved layout of agricultural land plots have been achieved, while the length and placement of country lanes have been optimized. The reforested agricultural areas within the specific land mass have been redesignated as a forest resource. The advantages and disadvantages of natural afforestation in land consolidation are identified in contrast to alternative approaches.The research findings can be used by territorial communities in the upgrade of land management practices, laying out and redesign of landscape parks and other nature conservation areas that include areas of business activity.

The land plots reallocation algorithm development in the course of land consolidation in Ukraine

Abstract: The issues of land plots reallocation in the course of land consolidation in Ukraine have been considered in the article. The place and role of land plots reallocation in the set of measures on land consolidation have been specified. The main algorithms of land reallocation used for land consolidation purposes in the national and international practice have been analyzed. The algorithm of land reallocation in the course of land consolidation in Ukraine has been suggested based on the peer land plots exchange. The algorithm has been tested at the land consolidation in Kyiv Region

The theory of combinations for land plot exchange modelling in the course of land consolidation

Abstract: The paper is aimed at the promotion of voluntary land consolidation through the improvement of land plots exchange. The issue of the existing land plots boundaries adjustment in the course of voluntary land consolidation has been singled out. Possibilities, advantages and risks of land plots exchange without changing the existing boundaries as a constituent of land consolidation measures have been substantiated. The improvement of approaches to land plots exchange modelling without the existing boundaries adjustment has been suggested. Demands to the formation of consolidated land tenures as the result of exchange have been singled out. Theory of combinations has been applied to specify land plots exchange options. Calculation formulas for the number of the optimal consolidated agricultural land tenure placement options have been suggested. The calculations can be applied in the optimization and heuristic approaches to land reallocation and at land consolidation performance evaluation. Suggested approaches facilitate the implementation of heuristic methods especially in non-standard conditions, allow to increase the number of developers, especially involving experts with little experience. The results can be used for land plots lease optimization.

Optimising Land Consolidation by Implementing UAV Technology

Abstract: The increase in population and the growing demand for food that accompanies it drive the need to achieve sustainable agriculture. Technological progress and methodological novelties provide tools that may support the processes of improving the spatial structure of agricultural lands, as well as their management. One of the examples may be the application of photogrammetric and remote-sensing products to facilitate land consolidation. In the following paper, the systematised procedure of conduct is investigated to determine the moments at which these products could be adopted. In identifying the possibilities for implementing the abovementioned tools, we analyse the legal regulations governing the process and the literature on the subject, as well as some practical examples encountered in surveying practice. In addition, the usefulness of such geospatial products is tested on data gathered during an exemplary UAV flight. We then investigate the issues with implementing the abovementioned tools and assess their advantages and disadvantages in smart agriculture. The research proves that reliable elaboration of the consolidation project concept is critical for its correct realisation, while modern measurement methods providing efficient, up-to-date, factual data facilitate the procedures and support rational decision making. Moreover, they enable us to ensure the necessary accuracy of the data for the scope of the land use and avoid analysing a compilation of several cartographic materials concerning the surveyed object. In the present study, the RMSExyz mean square error at the control points for the orthomosaic, generated using the Matrice 210 RTK v2 professional flying platform, is 5.6 cm, while for the orthomosaic created from images from the amateur drone Mavic 2 Pro RMSExyz, it is 9.2 cm. The results obtained also indicate the usefulness of low-budget drones during the land consolidation process.

Determination of the Regeneration Energy of Direct Air Capture Solvents/Sorbents Using Calorimetric Methods

Abstract: Regeneration energy and recyclability are important parameters that dictate the viability of a CO₂ direct air capture (DAC) process. In this study, differential scanning calorimetry (DSC) is used in conjunction with thermogravimetric analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR) to evaluate the regeneration energy required for CO2-loaded 3 M aqueous potassium sarcosinate (K-SAR) solvent and crystalline methyl-glyoxal-bisiminoguanidine (MGBIG) sorbent. Based on calorimetric measurements, for aqueous K-SAR, the sensible heat amounts to 1.5 GJ/tCO2 and the enthalpy of desorption is estimated at 3.68 GJ/tCO2. The total energy of regeneration will also include the enthalpy of solvent vaporization, which will depend on the thermodynamic conditions and the level of regeneration. For MGBIG, the total regeneration energy required was measured at approximately 7.0 GJ/tCO2. FTIR measurements were used to observe CO₂ and H2O release during the thermal regeneration process. For K-SAR, CO₂ release is seen to take place at temperatures greater than 80 °C and, for MGBIG, the CO₂ release takes place at temperatures greater than 100 °C. The moderate temperatures required for K-SAR and MGBIG regenerations compared to other DAC solvents/sorbents suggest that low-cost sources of heat, such as geothermal heat, could potentially be used for regeneration to drive down the cost of direct air capture.
