Sustainability leadership entails the processes, which leaders, policymakers, and academics undertake in order to implement sustainable development policies and other initiatives within their organizations. It encompasses approaches, methods, and systemic solutions to solve problems and drive institutional policy towards a more sustainable organization. Higher Education Institutions (HEI) play a particularly important role, especially with regard to their institutional leadership role in promoting sustainable development. There is a paucity of research focusing on sustainability leadership in universities. In order to address this gap, this paper discussed the concept of sustainability leadership based on literature and empirical insights. The study aimed to understand the main characteristics of sustainability leaders at HEI and the main challenges they are confronted with. Secondary research questions involved gender issues and positive outcomes of sustainability leadership. The empirical component of the study consisted of an online-questionnaire survey performed among leaders (n = 50) from a set of universities in 29 countries. The sampling scheme was purposive, based on the membership in the Inter-University Sustainable Development Research Program (IUSDRP). The study was explorative in nature, and the descriptive statistics were used for the analysis. Due to the purposive sampling, the participants from top management positions could be considered as experienced, and their views were assumed to be information-rich. With a self-evaluation, the respondents described their leadership style and their usual traits, with inclusive style and systemic thinking being predominant in the sample. Regarding the skills, the respondents selected the ability to innovate, to think long-term, and to manage complexity from a pre-defined set of options. Connectedness with interdisciplinarity and knowledge about organizational settings, as well as global challenges and dilemmas, were stated as important issues related to the knowledge required for being a leader. Regarding requirements for a change towards more sustainable universities’ curriculum adaptation, investments in education for sustainable development (ESD), sustainable procurement, and reporting were mentioned. The study also revealed that gender issues were taken seriously among the sampled institutions, which is an encouraging trend. Challenges seen in implementing sustainability leadership are, for instance, a lack of interest by the university administration and among some members of the academic community, as well as lack of expertise and materials or resources. Based on the empirical insights, a set of measures were listed and which may be adopted in the future, so as to allow leaders of Higher Education Institutions to enhance their sustainability performance.

Sand is considered one of the most consumed natural resource, being essential to many industries, including building construction, electronics, plastics, and water filtration. This paper assesses the environmental impact of sand extraction and the problems associated with its illegal exploitation. The analysis indicates that extracting sand at a greater rate than that at which it is naturally replenished has adverse consequences for fauna and flora. Further, illicit mining activities compound environmental damages and result in conflict, the loss of taxes/royalties, illegal work, and losses in the tourism industry. As sea-level rise associated with climate change threatens coastal areas, sand in coastal areas will play an increasingly greater role in determining the amount of damage from floods and erosion. The present analysis points to the need for swift action to regulate sand mining, monitoring, law enforcement, and international cooperation.

The rapidly increasing global populations and socio-economic development in the Global South have resulted in rising demand for natural resources. There are many plans for harvesting natural resources from the ocean floor, especially rare metals and minerals. However, if proper care is not taken, there is substantial potential for long-lasting and even irreversible physical and environmental impacts on the deep-sea ecosystems, including on biodiversity and ecosystem functioning. This paper reviews the literature on some potentials and risks to deep seabed mining (DSM), outlining its legal aspects and environmental impacts. It presents two case studies that describe the environmental risks related to this exploitative process. They include significant disturbance of the seabed, light and noise pollution, the creation of plumes, and negative impacts on the surface, benthic, and meso- and bathypelagic zones. The study suggests some of the issues interested companies should consider in preventing the potential physical and environmental damages DSM may cause. Sustainable mining and the use of minerals are vital in meeting various industrial demands.
