PAST EVENT: International Course: Long term socio-ecological research: What do we know from science and practice?The emerging interdisciplinary field of Long-Term Socio-Ecological Research, abbreviated LTSER, aims at observing, analyzing, understanding and modelling of changes in coupled socio-ecological (or human-environment) systems over longer, i.e. at least decadal, sometimes even centennial, periods of time. LTSER is focused on interactions between societies and ecosystems at various spatial and temporal scales. By including long-term monitoring, historical research, forecasting and scenario building, empirical and conceptual research as well as participatory approaches, LTSER aims at providing a knowledge base that helps to reorient socio-economic trajectories towards more sustainable pathways.
