Vienna, April 23-25, 2012The 2012-GIFT (Geosciences Information for Teachers) symposium will take place on April 23-25, 2012 during the general Assembly of EGU in Vienna Austria. The general theme of the workshop is «Water!» and will be dedicated to the study of the hydrological problems of our planet.
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above and below the surface of the Earth. It also involves the exchange of heat energy, which leads to temperature changes. The water cycle figures significantly in the maintenance of life, society and ecosystems on Earth. However, several problems threat water resources today, which are related to the unsustainable overexploitation of water resources, the lack of adequate water supply systems in many parts of the world, pollution, and an increase in the population at risk to water hazards. Such problems are caused by an ever increasing population, consumerism, urbanization and agricultural expansion.
As a consequence, water resources have already been deeply affected by global warming: sea levels have risen, glaciers have retreated. Sometimes water reservoirs are essential to the life in entire regions. In addition, the hydrological cycle is heavily affected by land use change which induces relevant variations of groundwater recharge. The above problems cause concerns in almost every sector of everyday life, and geo-engineers are seeking ways of mitigation. All water bodies are going to be affected by global warming, making knowledge of the water cycle essential for any kind of human activity. Entire regions on Earth would face extreme temperatures eventually associated with torrential rainfalls other regions would experience scarcity of water and droughts. In the GIFT workshop «Water!» all the different aspects of the water cycle will be described and discussed. Talks will focus on global freshwater availability and distribution, overexploitation of water, strategies for sustainable use of water in the future and the threats by environmental change, with examples of particular regions where global warming will have a major impact, such as the regions depending on the water supply from the Himalayan, Alpine and Andes mountain glaciers. The use of naturally occurring isotopes to "fingerprint" sources of water in precipitation and rivers, and the presence of hundreds of thousands of years old water underneath the deserts and other areas, will also be discussed.. Focus will also be put on climate model simulations for the 21st century, mitigation measures to reduce the magnitude of impacts of global warming on water resources, and water resources management and its impacts on other policy areas. As in every GIFT Symposium, contributions by the attending teachers on particular "off-the-program" activities that they may have had in their classrooms are particularly welcomed, either as poster or oral presentations, even if their subject is not directly related to the theme of the workshop. Also, a first step will be a guided visit to the Vienna Museum of Natural Sciences, on Sunday April 22 afternoon, followed by a small reception as an ice-breaker event.
