“…For one, the instrumental approach towards HESD seeks to instill particular sets of knowledge, skills, and attitudes in students in order to tackle the increasing complexity of sustainability issues (such as climate change, shoreline erosion, or interspecies living at the seaside) and the uncertainty associated with these issues [6,7]. Higher education is, in that respect, often considered the place par excellence to develop and enhance necessary competences of students: by means of the close intertwinement of research and teaching, higher education is able to offer the newest insights to students, and to train them in the ability to propose answers to (or even solve) contemporary and future sustainability problems [8,9]. Currently, research on HESD has identified crucial competences which are necessary in order to solve such challenges: systems thinking, anticipatory, normative, action-oriented, and interpersonal competences are increasingly considered interdisciplinary bundles that, when equipped correctly, will allow future generations to deal with our present-day problems [6,10,11].…”
