Going to the EGU this April? Don't miss these sessions!
We've surely missed some relevant sessions; if you know of others that should be on this list, please contact us!The Legacy of Mountain Glaciations
Convenor: Stefan Winkler
This meeting shall be an assembly of all intersted colleagues working on topics related to Mountain Glaciations to discuss future collaborative research initiatives. It is linked to an EGU session (GM 10.1). Our group is aiming to evaluate the relative importance of different geomorphic and climatic processes in the evolution of mountain glacier records worldwide. We want to address the wide diversity of formerly and currently glaciated mountain ranges and the planned research initiative will focus on analyzing regional contrasts in the impact of climatic factors on the glacier mass balance and their effect on landforms, landscape evolution, and timings of maximum glaciation.High mountain hazard assessments
Convenor: Christian Huggel
Towards developing international standards in high mountain hazards assessment and mapping.Dynamics of Forest Populations and Shift under Climate Change
Convener: Fabrizio D'Aprile
How variability in climate conditions influences vegetation responses in species composition, dynamics of plant populations, and potential changes in plant species range is the main theme of this session. Historical records, recent and current research, and short- and long-term scenarios at any scale level are also of interest provided that methods used and expected results are shown. Relationships with CO2 balance, fauna, and impact of human uses are can be presented if the main focus rests on vegetation.Response of terrestrial ecosystems to climate change: Learning from experimental manipulations and natural gradients
Conveners: Frank Hagedorn, Werner Borken, Andreas Schindlbacher
Terrestrial ecosystems will respond to future changes in temperature, precipitation, air humidity and atmospheric CO2 concentration. Numerous field experiments manipulating single or multiple factors were performed during the past decades. Results of these experiments often depend upon the ecosystem types, site characteristics and the variations in the intensity, duration and combination of manipulations. Alternatively, numerous biogeochemical studies have been conducted throughout ongoing climatic changes in past decades or along natural climatic gradients. In our session, we encourage novel contributions from both manipulative experiments and climatic gradient studies or a combination of both encompassing biogeochemical processes, plant and microbial aspects to improve our understanding of the climatic control on ecosystem processes. Contributions synthesizing experimental outputs and providing better, holistic process understanding are highly welcome as well.Mountain climates: processes, change and related impacts
Conveners: Wolfgang Schöner,Sven Kotlarski, Douglas Maraun, Elisa Palazzi, Walter Immerzeel, Heimo Truhetz, Erin Gleeson, Nick Pepin, Andreas Gobiet
Mountain climate shows high spatial variability due to complexities in terrain, steep (yet temporally variable) vertical gradients in climate elements, and inhomogeneities induced by transitions with elevation to the cryosphere and between vegetation zones. The resulting patterns of climate and climate change are often highly complex and very demanding in terms of monitoring, modeling, and analysis.
This session is devoted to a better understanding of climate processes and their modification induced by global environmental change in mountain and high elevation areas around the globe. We invite contributions that investigate climate processes and climate change in mountainous areas, based on monitoring (in situ and remotely-sensed observations) and/or modeling activities. Particularly welcome are contributions that merge various sources of information (modeling, monitoring) and reach across disciplinary borders (atmospheric, hydrological, cryospheric and ecological sciences) to cover new ground in the understanding of mountain climate and mountain climate change.
Further by invitation of the Mountain Research Initiative, presentations that focus on past and projected changes in high-elevation climate, including elevation-dependent effects (e.g. warming, precipitation change), their impacts on the water cycle (in particular from the changing cryosphere), and the social and ecological implications for downstream areas are welcome. Presentations about novel data sets, multidisciplinary data analysis and observational and modelling approaches focused on mountainous regions are especially welcome.Mountain soils
Conveners: Alevtina Evgrafova, Sebastian Zubrzycki, Marc Oliva, Erin Gleeson, Michele D'Amico
Mountain soils play an important role in the global carbon cycle, controlling erosion processes, providing essential ecosystem services and water management in high-altitude regions across the world. Factors such as climate change, deforestation and unsustainable farming and resource extraction methods can cause land degradation and desertification as well as a loss of soil variability and biodiversity in mountain areas. This session aims to bring together current knowledge pertaining to soil-related issues and possible strategies for sustainable mountain development.Glaciers and ice caps under climate change
Conveners: Jon Ove Hagen, Georg Kaser, Matthias Huss, Nicholas Barrand
Mountain glaciers and ice caps are major contributors to sea-level rise and have large impacts on water balance of local basins. This is a general session on glaciers and ice caps where the relationship to climate forms a particular focus. The IPCC AR5 of Working Group 1 covers Earths Glaciers and Ice Caps outside the ice sheets under the heading of Glaciers and shows that, despite much progress recently provided by the community, we are still left with substantial unknowns. We need to acquire more data, both from new fieldwork and release of unpublished data from prior years on mass changes of glaciers and ice caps from all regions of the world. We need to improve the understanding of the processes behind the changes, and we need to improve the application of models of different complexity. We welcome presentations on all aspects of mass changes; current, past and future changes based on field observations, remote sensing and modeling. Studies of physical processes controlling accumulation and ablation including calving and submarine melting, are especially welcome.Outdoor recreation impact: assessment, monitoring and management
Conveners: Aleksandra Tomczyk, Marek Ewertowski, Teiji Watanabe
Natural protected areas can provide sustainable recreational opportunities, but they are always facing negative impacts caused by visitors. Degradation of environment due to recreational use has attracted scientists and protected-area managers. As a result, a variety of assessment and monitoring methods have been developed by now. Conventional approaches include field-based surveys and repeat measurement of site-specific impacts, which has been widely used to monitor degradation, because of its easy implementation. Recent advances in technology enable the development of new methodological approaches, allowing for understanding not only point-specific, two-dimensional changes, but also to study volumetric transformations or collect time-series of spatially dependent data. These approaches include 3D reconstruction of the trail surface based on (1) unmanned aerial vehicle (UAV) photography and or ground-based photographs, which can be subsequently processed through the structure-from-motion (SfM) process to generate detailed digital elevation models, (2) terrestrial laser scanning (TLS); (3) GPS loggers; (4) time-laps cameras, etc. The development of the methodology would lead to better management of recreation in natural protected areas. This session will present the state-of-the-art methodologies of monitoring and assessment of environmental impacts of outdoor recreation in different environments, and discuss their application, which would be beneficial to managers of natural protected areas of high conservation value. We invite contributions from wide range of topics covering all aspects of outdoor recreation impacts and their sociological and environmental consequences. Studies linking direct field-based observations with modelling and predictions are particularly encouraged.Water resources - assessment, management, and allocation - in (semi-)arid regions
Conveners: Jan Friesen, Ralf Ludwig, Laura Foglia, Leonor Rodriguez-Sinobas
Semi-arid regions are facing the challenge of managing its water resources under conditions of increasing scarcity, drought, and concerns about water quality. Already, the availability of fresh water in sufficient quality and quantity is one of the major factors limiting socio economic development. Especially, in terms of hydrology semi-arid regions are characterized by very complex hydro- and hydrogeological systems that often exhibit extreme behavior. The complexity of the water cycle contrasts strongly with the poor data availability, which limits the number of analysis techniques and methods available to researchers.
Discussing frameworks that provide water assessment, management, and allocation solutions for water and data scarce regions is the focus of this session.Resilience and vulnerability assessments in natural hazards and risk analysis
Conveners: Sven Fuchs, Margreth Keiler, Thomas Glade, Maria Papathoma-Koehle
The assessment of vulnerability and resilience is an essential part within natural risk analysis. Commonly, these assessments relate purely to the stability of buildings or to chances that people will be affected. These investigations relate in particular to natural and engineering science approaches, but other types of vulnerability are also inherent, yet are often not covered but need also to be assessed. Similarly, resilience is a new approaching concept in risk assessments and needs to be explored. These relate among other things to coping capacities and strategies of affected people and communities, to intangible and indirect economic losses, and to communication and education networks. In addition to partially addressed aspects of vulnerability there is neither a uniform and well-excepted technique or method or standard available to assess vulnerability within its multifaceted nature. Different approaches and disciplines often remain in their corner and interdisciplinary approaches are rare.
This session aims to summarize assessments of different types of vulnerabilities (e.g. social, personal, structural, economic, political, environmental) and resilience and to present applications for different natural phenomena. The main focus herein is to present different strategies based on developments from different disciplines and to discuss these according to similarities, but also differences. The role of vulnerability assessment within risk analysis is of particular importance. Researchers as well as practitioners are encouraged to present case studies and applications, conceptual ideas and new methods on the analysis of vulnerability to natural hazards. In order to allow a fruitful discussion and exchange between the different disciplines we encourage a particular focus on the demonstration of the employed methodology and the data bases available for respective research or application.
