Povzetek: Beneath the Earth’s surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sed-imentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and reg-ulates services critical to ecological health and human well-being. Subterranean ecosystems are integral to majorbiogeochemical cycles, sustain diverse surface habitats, and serve as the primary source of irrigation and drinking water.They also offer non-material benefits, including scientific discovery, education, and cultural practices. Yet, these contri-butions often go unrecognised, partly due to the lack of a unified synthesis of ecosystem services across terrestrial, fresh-water, and marine subterranean compartments. This gap limits effective communication of their value to scientists,practitioners, and the public. Through a systematic expert-based review, we show that subterranean ecosystems contrib-ute to up to 75% of classified ecosystem services. Notably, many of these contributions are described only qualitatively,lacking numerical or economic quantification. Next, we list examples of the main ecosystem services provided by subter-ranean systems to offer a global overview of their multifaceted value and vulnerability to environmental change. Webelieve this synthesis provides researchers and practitioners with concrete examples to communicate more effectivelythe importance of subterranean ecosystems to diverse audiences.

Povzetek: Measuring sustainability as an efficient tool to achieve sustainable development and improve economic, social, and environmental aspects is always fraught with complications. In this sense, developing a suitable approach for evaluating and recognizing the strengths and weaknesses across these dimensions is paramount. Given the inherent uncertainty in data for many real-world applications, the primary aim of this paper is to present a data envelopment analysis (DEA) model for evaluating sustainability within a stochastic environment. The proposed model is non-radial and incorporates undesirable outputs, enabling the assessment of overall sustainability as well as each of the economic, social, and environmental dimensions simultaneously. This multi-dimensional evaluation capability is a key advantage of the proposed model. Additionally, the proposed model is based on input excesses and output shortfalls. Another notable advantage is the incorporation of the assumption of managerial disposability when dealing with undesirable outputs. To demonstrate the applicability of the proposed model, data from 59 diverse countries across Africa, Europe, North America, and Asia were analyzed over a 12-year period (2010–2022). The country selection was designed to capture global heterogeneity in development levels, policies, and environmental conditions, allowing for robust cross-continental comparisons. Key findings reveal that: (1) Europe achieves the highest stochastic sustainability scores, while North America performs poorest; (2) Environmental sustainability shows the most success cases globally, whereas social sustainability lags; (3) Significant trade-offs exist between economic growth and environmental protection.

Povzetek: National Road Authorities (NRAs) draw on a wide range of technologies and tools to support robust decisions on asset maintenance. However, in recent years there has been significant progress in the development of sensing technologies for data collection and advanced techniques for data processing. These technologies present an opportunity to improve asset management decisions, but also present a challenge for NRAs, as they seek to realise the benefits. This contribution presents the appraisal methodology for emerging technologies proposed by the INFRACOMS project commissioned by the Conference of European Directors of Roads (CEDR). The methodology provides objective appraisals since technologies are scrutinised against proposed subsequent criteria. Cost factors, potential benefit categories and limitations are identified. Technologies are ranked by key imperatives and scored. Technologies with a good score are evaluated more thoroughly, which may need specialist input and discussions with the technology supplier. It results in a technical score, a benefit/cost assessment and identified steps in a roadmap toward implementation. The NRAs can share their individual appraisals in a database. The second part of the project develops an action plan to guide NRAs in adapting and implementing promising emerging technologies and training sessions on the use of the developed appraisal toolkit.

Povzetek: Higher Education Institutions (HEI) face increasing expectations to engage in sustainability reporting despite limited resources and heterogeneous practices. This study explores how Joint Sustainability Reports (JSR), built on the EU Voluntary Sustainability Reporting Standard for non-listed SMEs (VSME), can serve as a cooperative and digitally supported framework to enhance transparency, comparability, and efficiency while strengthening universities’ third mission of societal engagement and knowledge transfer. Qualitative interviews with six sustainability experts from German and Austrian universities of applied sciences (UAS) highlight persistent challenges such as data gaps, staffing shortages, and weak strategic anchoring. The findings show that VSME-based JSRs, through shared data collection, centralised coordination, and modular reporting, enable resource and data pooling, standardised indicators, and cross-university synergies. By making social contributions more visible and credible, JSRs reinforce accountability and advance universities’ third mission in fostering community outreach and sustainable development
