Workshop 2.2.D: Mountain biodiversity and ecosystems under global change
Mountains worldwide host very rich biodiversity, are home to hundreds of millions of people, and provide billions of upland and lowland inhabitants with vital ecosystem services and sources of livelihoods. However, mountains, including their highest alpine habitats, are increasingly exposed to changes in climate and land use, environmental pollution, large-scale political and socio-economic transformations, and unsustainable management of natural resources. In the face of the growing challenges brought about by human activities, effective policies and management approaches are needed to safeguard the natural assets that are underpinning human wellbeing along the elevational gradient from the highlands to the lowlands and ultimately “ensure the conservation of mountain ecosystems” (United Nations Sustainable Development Goal 15.4). The formulation and implementation of such contextually relevant approaches requires a thorough understanding of how mountain biodiversity and ecosystems respond to direct and indirect drivers of change; how they contribute to human wellbeing across scales; and how their conservation can be achieved in the context of competing development goals, limited resources, and complex governance structures. However, currently we have a limited understanding of the drivers that operate at different scales and within different taxonomic groups along the elevational gradient; of the importance of variation in physical, biotic, and abiotic factors on the distribution of species across habitats; and of how changes in biodiversity and ecosystems in mountains affect the provision of ecosystem services and ultimately the wellbeing of populations in both highlands and lowlands. Many of these uncertainties limit our ability to develop robust scenarios for the future. With this session the Global Mountain Biodiversity Assessment (GMBA) in collaboration with the Mountain Research Initiative (MRI) aim at catalysing research efforts towards a sustainable future for mountain biodiversity and ecosystems worldwide.
The goals of this session are: to review current knowledge and knowledge gaps in mountain biodiversity and ecosystem sciences under global change, including the effect of and interaction between large- and small-scale drivers of change to formulate research priorities toward advancing mountain ecosystem and global change science, notably in terms of identifying species and habitat of high conservation priority. We particularly welcome contributions from the community of mountain scientists working in high alpine ecosystems and who are applying different methods such as monitoring, assessments, and predictive modelling.
