Formation of a network of test under-satellite fields in the agro-environmental monitoring system

Abstract

Goal. To scientifically substantiate the creation of a network of test sub-satellite fields in the system of agro-environmental monitoring. Methods. System analysis. Detailing of the «CORINE Land Cover» classifier to the 4th level was performed taking into account international experience and standards, EUNIS classification, and its improved version developed by the authors [14] to describe the biotopes of the Forest-Steppe zone of Ukraine. Results. Modern sources of space information of low and high spatial diversity, which are used in the system of satellite agro-ecological monitoring, are presented. Based on the version of the European classification of the land cover «CORINE» they highlighted the results of its expansion to the fourth level in the part «Agricultural areas», adapted to the conditions of Ukraine. The creation of a network of test agricultural sub-satellite fields in accordance with the natural and climatic features of Ukraine is substantiated. The structure of the test field passport under international and national standards is given. Proposals for the creation and spatial placement of test fields in the system of scientific institutions and research farms of the National Academy of Agrarian Sciences of Ukraine are submitted. Conclusions. One of the factors for limited use of satellite information resources in the system of agro-environmental monitoring, management, and environmental and agricultural activities is the unformed specialized network of satellite test fields, which is an important component of processing satellite imagery. In addition, the network of permanent fields will be an important element of systematic monitoring of assessment, and forecasting of the impact of climate change on the agro-sphere of Ukraine. Taking into account the available scientific and methodological potential of scientific institutions of the National Academy of Agrarian Sciences of Ukraine, their location under climatic zones, and specifics of economic activity, it is proposed to create networks of specialized sub-satellite test agricultural fields: in the zone of Polissia — 2, Forest-Steppe — 2, Steppe — 3. In the future, the network of such fields can be expanded according to thematic tasks and the need to detail spatial information.
