The evolution of the digital transformation presents new challenges and many new opportunities, and provides unique solutions to individual issues, both for sectors and regions. The challenges posed by the digital world have a significant impact on social and economic processes, as well as our environment. This paper aims to provide an indicator-based understanding of the main characteristics of digitalization promoting sustainable development in the member countries of the Visegrad Cooperation. The main goal of this research is to study the relationship between digitalization transformation and sustainability together. One of the basic indicators of the article is the Digital Economy and Society Index (DESI). We examined interconnections between the dimensions of the DESI index and the indicators of the Sustainable Development Goal (SDG) targets together in the V4, presented the change, evaluated the selected countries based on these aspects, and set up their ranking. Competitiveness performance data shed light on the situation in Hungary within the V4 countries, pointing out the strengths and shortcomings. The results show the extent of digital performance in each country and the relationship between their digital performance and sustainability indicators.
Drought phenomena have been frequent in Hungarian history. One of the most important sectors in Hungary is agriculture, so the agricultural drought is a particularly important area to be examined. The purpose of the study is to determine how vulnerable each county (NUTS-3 regions) is to the expected effects of drought. The study provides an assessment framework of drought-related vulnerabilities and the preparedness of drought policies at the NUTS-3 level in Hungary. The drought-related vulnerability of NUTS-3 regions was determined by selected exposure, sensitivity, and adaptive capacity indicators. The calculation of drought vulnerability is based on the IPCC 2007 methodology, while the input data were derived from the National Adaptation Geo-information System online data platform and Hungarian agro-statistical data sources. An assessment framework of drought-related policy performance of NUTS-3-level climate change strategies was developed. The evaluation methodology is based on a specific scorecard of evaluation criteria related to the performance of the county’s drought-related objectives and measures. According to the relationship between the county’s drought-related vulnerability and policy performance, the counties were classified into four types. The main results show that several counties fail the target by overestimating the role of drought prevention, with little vulnerability index. In contrast, many counties are not adequately prepared for the impacts of drought, despite their high vulnerability index.
In this study, the Cobb Douglas production function was built in order to investigate the linear economy, the redesign of intralogistics in a company. Authors have investigated a production function that describes the connection between the production of liquids, energy efficiency and water usage based on the logistic processes. The authors were able to build and simplify it to a linearized Cobb Douglas equation. With the help of mathematical-statistical analysis, the authors found that energy efficiency and water usage have a negative effect on production due to European legal considerations and logistic improvement could help in the solution of the problem. Then, the differences between the linear economy and the circular economy were examined. As a summary, a SWOT analysis exploring the differences was prepared.
On the basis of common and unified methodologies, NUTS3 (county) level climate change strategies have been completed in Hungary. The strategies also consist comprehensive inventories of greenhouse gas (GHG) emissions, as well as quantified decarbonization (emission reduction) targets for the years of 2020, 2030 and optionally, 2050. The primary objective of the paper is to identify the spatial structure of the GHG emissions and to assess the interconnection between NUT3 level economic development and emission patterns. Comparative analyses of the county's decarbonization targets are also presented in order to assess their contribution in the national commitments under Paris Agreement. Results suggest that NUTS3 level CO2 emissions show a typical spatial pattern with a strong interrelation with county's socio-economic typology. Finally, the paper provides suggestions to integrate the regional characteristics of decarbonization into county's transition to sustainable development.
