Directions for a sustainable Rehabilitation of forest fire Areas: In den letzten Jahren kam es vermehrt zu Waldbrandereignissen in Österreich. Laut der nationalen Waldbranddatenbank wurden alleine im Jahr 2013 130 Ereignisse registriert, bei denen mehr als 100 Hektar Nutz- und Schutzwald zerstört wurden. Diese Feuer werden durch ein Zusammenspiel von Wetter, Vegetation und Landnutzung ausgelöst, so dass sie sehr anfällig für Veränderungen sind. Insbesondere durch die zukünftige Abnahme von Niederschlägen im Sommer kommt nicht nur europaweit, sondern auch bei uns zu einer weiteren Zunahme von Brandereignissen. Waldbrände haben erhebliche Auswirkungen auf Landökosysteme und können neben den direkten Schäden am Wald zu einer Minderung von Waldfunktionen führen. Im Rahmen des Projektes werden unterschiedliche Maßnahmen zur raschen Wiederherstellung einer schützenden Vegetationsdecke untersucht. Die relevanten Prozesse von Pflanze-Boden-Feuer müssen verstanden werden. Es werden mehrere Versuchsflächen angelegt und mehrjährig hinsichtlich Vegetationsdynamik, Bodenentwicklung und Erosion beobachtet. Die erhobenen dienen als Grundlage für Modelle, um standortangepasste Maßnahmen für Waldbrandflächen zu entwickeln.

The presence of technologically critical elements (TCEs) in our environment is constantly increasing. There is a complete lack of fundamental and scientifically proven knowledge about the quantity of TCEs present, the cycles of TCEs with regard to their formation and degradation, and the associated potential health risk. The TecEUS research project has therefore set itself the goal of thoroughly investigating the presence of TCEs in the environment as well as their behaviour and effects on humans. A novel technology (ICP-MS Inductively Coupled Plasma Mass Spectrometry) will be used to capture details of TCE in the environment. In addition, it will be systematically tested to what extent urban green infrastructures (green facades) can contribute to the binding of TCE. This is particularly relevant with regard to the human health of the urban population and the assessment of health risks. The TecEUS research project aims to provide new knowledge on the following: A | TCEs accumulation in urban spheres (water, plants, soil); understanding of their formation and behaviour; B | effectiveness of green facades as a filter system for TCEs and their potential as a preventive measure in the field of human health; C | occurrence and increase of diseases depending on the increase of TCEs in air and agricultural products; D | assessment and modelling of occurrence, behaviour and impact and of TCEs in urban space using the example of Vienna. Due to its interdisciplinary orientation, the Tec-EUS team is able to consider the set project goals holistically, whereby the following findings can be generated as output: A new analytical method for quantification and tracking of TCEs in the environment will be applied and tested; distribution and occurrence of TCEs in urban spheres will be provided by an interactive system; binding and filtering effects of green facades with respect to TCEs will be demonstrated; the Viennese urban population and urban gardeners* will be used as active 'Citizen Scientists'; socio-economic effects, impacts and dynamics of TCEs will be modeled using the example of Vienna; socio-economic effects of green facades will be investigated as a sustainable precautionary measure; basis for modeling potential health risks will be given.

With the establishment of modern transport connections, which began in Vorarlberg at the end of the 19th century, many old routes lost their importance. Those old paths were and still are the expression of centuries-old socio-economic connections. Trade in goods, cattle drive and (temporary) migratory took place on them. They thus form an essential part of Vorarlberg's history. Reference has already been made to this cultural-historical significance (see Tiefenthaler, 2004 and 2008). The aim of the pilot study 2018 was to work out the methodology for an inventory of historical ways Vorarlberg and to test it as an example for two selected municipalities. As part of the results presentation and discussion with representatives from the communities and the state, the outstanding questions and recommendations for a follow-up project were pointed out. In the course of a continuation of the project, it is necessary - to determine the depth of preparation for a possible overall assessment of the country. - Are surveys at supraregional level required? Should be focues on historic main traffic axes? Are local links with their historically material substance important sources for historiography of Vorarlberg? - These and other questions call for a well-grounded strategy that includes clear objectives in terms of capture and conservation. - Since many paths do not end on the border of the municipality, it requires a cross-community cooperation. This guarantees access to a wide range of historical materials necessary for a sound historical investigation. The in-depth study of the pilot project will - clearly define the basics and objectives for the preservation of historical paths in Vorarlberg for decision-making. - The project clarifies links with and possible findings in existing tools (GIS tools, font and image databases, archive sources) for a larger project planned and an application-oriented approach. The aim of this project is to give the historical transport routes a firm place among Vorarlberg's cultural heritage. So far, it seems very promising to trace the previous descriptions of relationship, the old maps and reconstructions on site and to search for existing substance, which findings in the course of the Inventory of Historical Stone Walls have already shown. The methodological approach of the project serves as a basis to decide further research and leads to supporting the administration and planning authorities. The findings should be provided internationally through publications. Networking on a scientific level will be enabled. Furthermore, it will call the attention of the users, residents and tourists to the importance of the historical routes and lead to a respectfully handling of the valuable cultural heritage.
