Spatio-Temporal Distribution and Trends of Major Agricultural Crops in Romania Using Interactive Geographic Information System Mapping

This research study presents the spatio-temporal distribution of the main agricultural crops in Romania using a modern digitalisation technique, namely interactive GIS mapping. Interactive GIS mapping includes various features specific to the development of sustainable Romanian agriculture, including the arable area of Romania, information on the area (hectares) cultivated with corn, wheat, sunflower, and rape during the 1990–2018 period, the degree of mechanisation, the number of tractors, and information regarding the landforms, a natural factor in relation to cultivated surfaces. Agricultural land should be properly used based on its ability to meet the demands of consumers of traditional Romanian products with an ecological label, but also the needs of the local population, and, at the same time, to ensure the sustainability of the natural environment through the practice of ecological agriculture. The purpose of this research is to provide an overview of the current state of the main agricultural crops in Romania. From a theoretical but also practical point of view, this research presents, for the first time, a retrospective analysis of each county in Romania in terms of the geospatial distribution of major agricultural crops using interactive GIS mapping. Geospatial data were processed in ArcGIS Geographic Information System 10.7.2. The results of this study show that the most extensive cereal areas at the county level in Romania are corn and wheat. The largest areas cultivated with corn and wheat in 2018 were recorded in the Western Plain, the Romanian Plain, and the Moldavian Plateau. For wheat, increases were also recorded in the Dobrogea Plateau. The intensification of labour productivity and the promotion of the sustainability of the natural environment in Romania is presented through the main indicator (the number of tractors) of the degree of mechanisation of agriculture. The higher values of this indicator are in the counties of Bihor, Timiș, and Maramureș. Limitations in Romania’s agricultural data present substantial challenges to the sector’s development and sustainability. Addressing these challenges is essential for informed decision making, policy formulation, and effective resource allocation.
