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.

The digital world holds many opportunities and challenges for us. These changes affect all the basic pillars of sustainability, including the economy, society, and the environment. They primarily affect companies, specifically theirproductivity and profitability, so it is not an exaggeration to say that nowadays, we can consider the digital maturity of companies as one of the driving forces of the economy. The research aims to prioritise the digital competence of theworkforce among the indicators of digital maturity, which, based on my hypotheses, has the greatest impact on the profitability of businesses. Another main research goal is to map the cognitive sustainability-related activities of humanresources employed by companies and then present the relationship between digital maturity and sustainability through human resources. In this study, the digital maturity of companies was assessed, especially the role of human digital skills in productivity based on Maslow’s business pyramid and a SWOT analysis. I compared the cognitive sustainability-related activities of human resources and examined how this affects the company’s effectiveness.
