Satellite data are a relevant part of information, required for sustainable environmental management, assessment of the impact of economic activity of ecosystems, determination of risks, related to global climate changes, desertifi cation processes, loss of landscape and biotic diversity. Aim. To substantiate the reasonability and prove the effi ciency of using satellite data in the agroecologic monitoring system regarding the impact of climate changes on vegetation, processes of soil erosion degradation, and assessment of landscape diversity. Methods. The study was conducted in the territory of Ukraine. It involved the application of SWOT and Gap-analysis methodology, materials of NOAA satellite observa- tions, Sentinel, different spatial resolution, methodological and regulatory provision of the Institute of Agroecology and Environmental Economics of the National Academy of Agrarian Sciences regarding satellite monitoring of the structure of agrolandscapes, norms of establishing a network of testing agrarian grounds, list of vegetation state indicators, in par- ticular, “Remote sensing of the Earth from space. Land data about controlling the condition of plantings and performance of agricultural crops. General requirements: DSTU 7307:2013”, “Remote sensing of the Earth from space. Ground in- spection of plantings. Classifi er of objects and functions: SUC 01.1-37-907:2011”, “Methodological recommendations on establishing the network of testing agrarian grounds in the system of monitoring of plantings using the materials of cosmic information”. The investigation on the impact of climate changes on vegetation state was conducted on the territory of three natural-climatic zones which were geographically represented by Chernihiv, Poltava and Zaporizhzhia regions re- spectively. The determination of the threat of erosion degradation of arable lands and landscape diversity was performed on the territory of two administrative districts with high level of ploughness of agrolandscapes, intense agrarian produc- tion and manifestation of erosion degradation of lands. Results. Inadequacy of the traditional system of agroecological monitoring was determined. It was proven that it was reasonable to have comprehensive application of satellite data regarding climate warming within the natural climatic zones and its impact on vegetation according to the normalized dif- ference vegetation index (NDVI), erosion degradation of soils and landscape diversity. According to satellite data of the National Oceanic and Atmospheric Administration (NOAA), the correlation analysis was performed on the connection between the dynamics of the sum of effective temperatures and the sum of NDVI values for the vegetation period. There was positive impact of climate warming on vegetation state according to NDVI index in the zone of Polissia and Forest- Steppe. The correlation coeffi cients were R = 0.64 and R = 0.77 respectively. In the Steppe zone the correlation coeffi cient dropped down to R = 0.35 which demonstrated the elevated risk of droughts. Conclusions. Satellite data of Sentinel-1 were used to determine critical zones of erosion degradation of arable lands, requiring preservation and their inclusion to the natural fi elds, which had a positive impact on the optimization of agrolandscape diversity.

At this stage scientific and technological progress, which reaches unprecedented levels is characterized by the continuous creation of new and improved existing technologies and means of production. In turn the aviation industry is the realization of new achievements and achievements in the practical aspect of application. There are the developments of new equipment, both on-board and on-board; creation of powerful engines; updating fleet of aircraft, as well as designing new types. But along with such positive achievements at the first glance, aviation transport remains a large source of harmful factors for the environment, the first of which is usually in the vicinity of large cities, and the latter, in turn, within large citiesTherefore, the current situation leads to the necessary, development and implementation of a comprehensive environmental safety program in aviation transport. Most recently, experts and specialists in the field of the aviation industry have concluded that the using of passenger flight services as well as freight aircraft services have been much more efficient from an economic point of view than the using of automobile transport.So, in general, a passanger jet needs 100 times more fuel for a flight than an automobile. But if you talk about fuel consumption for a trip to a particular distance, in this case, that the needs of the aircraft will be almost 2 times less than for the automobile transport. Let's consider this situation on a concrete example. How will the amount of necessary fuel for the Boeing 747 passenger aircraft and the Honda Civic passenger car differ, in overcoming the distance from Chicago to London? Fig. 1. Airplane and automobile movement relative to the same distance with different costs of high-quality fuel Chicago London Passenger jet Automobile 200 liters = 53 gallons of fuel 532liters = 136 gallons оf fuel

During the last 50 years the humus content in the arable layer of the soil in the basic agrarian regions of Ukraine (steppe and forest steppe) has diminished by 15-18 %. Optimisation of the structure of land areas and stabilisation of agricultural landscapes should be based on the soil indicators that ensure conservation of land. It has been substantiated that the contour-meliorative system of land use under the conditions of the development of farming enterprises as the main form of the contemporary land system should be modernised. Primary water collectors should be selected as the object of formation of this system. There are proposed new directions of measures to improve the protection of the soil mantle. The results of the conducted investigation will help stop the soil fertility deterioration process because of excessively high share of arable land and disregard of the ecological and agronomic land-use norms. It is prognosticated that the area of the arable land will decrease by 5.1 mln. ha, but the area of forests and protective plantations will increase by 2.7 million hectares, reaching the proportion of the territory covered by forests to 22 %.

The Ukrainian people, with the votes of 90.3% of those who took part in the All-Ukrainian referendum on December 1, 1991 in support of the Declaration of Independence of Ukraine, confirmed their right to land established by the Declaration of State Sovereignty of Ukraine. According to the Constitution of Ukraine, land is recognized as the main national wealth, which is under special protection of the state. The State Committee of Ukraine for Land Resources was established in 1992 of , which was directly subordinated to the Cabinet of Ministers and implemented the state policy in the field of land relations was carried out by the said central executive body.Beginning in 2000, the State Committee was transformed into the State Agency, which in 2008 was reorganized into the State Committee, then returned to its previous name, and in 2014 was transformed into the State Service of Ukraine for Geodesy, Cartography and Cadastre (State Geocadastre). For the latter body, the powers to implement state policy in the field of geospatial data infrastructure, topographic, geodetic and cartographic activities instead of implementing state policy in the field of land relations became decisive. Land relations are public relations concerning the possession, use and disposal of land. They are represented by a separate branch of law - land, which belongs to its profiling branches. This branch exists in direct connection with the basic (fundamental) branches of law that regulate primary social relations. Topographic, geodetic and cartographic activities, the sphere of national infrastructure of geospatial data do not belong to land relations. The activities of the State Agency have been directed and coordinated by five Ministries for 17 years. The implementation of state policy in the field of land relations has become a secondary task for the second body. The purpose of the studyis to analyze the process of transformation of public authorities on the formation and implementation of state land policy, its impact on land use in the state and justification of directions and ways to preserve the main national wealth. It is established that imperfection in the field of land use and protection management and the lease model of agricultural land use have deprived the economic motivation to introduce soil protection technologies in production, due to which most of the soil cover is in pre-crisis condition. A stable negative balance of humus, nitrogen, phosphorus, and potassium has been formed in agroecosystems. That was recognized as an urgent comprehensive program to neutralize challenges and threats in the environmental sphere, the National Security and Defense Council adopted a decision on this issue in March 2021.The paper focuses on the reference to state control of land use, supports the idea of improving the content of land monitoring and the procedure for its conduct, suggests ways to increase the role of state bodies in improving the land management system

With a unique soil cover, Ukraine has been leading in the production and world export of grain crops and sunflower, providing grain needs for 400 million people in recent years. However, an unbalanced scarce farming system has caused increased soil degradation and a decrease in its fertility level. In connection with this, the relevance of the protection and rational use of land has increased significantly, as the tendency to worsen the quality of land has intensified, and sometimes it became a crisis. Russian aggression has led to the seizure and destruction of part of the land resource, soil cover pollution, mining of significant territories, direct physical damage to Ukrainian black soil. The article is aimed at studying the implementation in the country of the constitutional provision for the special protection of land as the main national wealth, as well as the main directions of ensuring the reproduction and increase of soil fertility. The relationship between land and civil law is analyzed, the peculiarities of the presentation of the provisions of Article 14 of the provisions of the Constitution of Ukraine, Civil Code, Law of Ukraine "On Land Protection" are disclosed. The necessity of improving a number of provisions of the Law of Ukraine "On Land Protection", the legal regime of especially valuable lands is substantiated, preservation of independence of land law as a separate legal system.
