Urban sprawl is an essential environmental issue to be monitored and forecasted in order to think about alternatives that could lead to a more sustainable future development. Thus, the objective of the project presented here is to simulate the past and future transformation of suburban land use patterns in the Vienna Region. (The paper describes some(More)
Increased tropospheric ozone concentrations cause damage to both human health and the environment. To assess the exposure of forest areas and selected tree species to ozone, it is necessary to calculate the ozone exposure distribution. The present article describes the application of an ozone interpolation model to the calculation of the ozone exposure(More)
As climate change appears, strategies and actions will be necessary to cope with its effects on environment and society in the coming decades. Current climate conditions can be observed everywhere in the world but future climate conditions can only be estimated through climate simulations which produce huge amounts of quantitative data. This data leads to(More)
This contribution explores the effects of climate change on open spaces and street canyons in urban environments, using the “Aspern” New Town development in Vienna as a principal case study. Specifically, the effects of alterations in the urban fabric are analysed with regard to sun exposure and ventilation. Results of future regional climate scenarios are(More)
The paper discusses a model that performs the simulation of polycentric development of suburban systems. It introduces different settlement pattern growth speeds in different suburban regions considering housing area densification and land use change from open space to built up area. Accordingly, the approach concentrates on a Spatial Agent Model (SAM) to(More)
GOAL, SCOPE AND BACKGROUND Ozone is the most important air pollutant in Europe for forest ecosystems and the increase in the last decades is significant. The ozone impact on forests can be calculated and mapped based on the provisional European Critical Level (AOT40 = accumulated exposure over a threshold of 40 ppb, 10,000 ppb x h for 6 months of one(More)
The potential distribution and composition rate of beech, sessile oak and Turkey oak were investigated for present and future climates (2036–2065 and 2071–2100) in Hungary. Membership functions were defined using the current composition rate (percentage of cover in forest compartments) of the tree species and the long-term climate expressed by the Ellenberg(More)
This paper deals with climate change mitigation and addresses waste heat reuse as a measure which is until now considered only to a limited extent. The City of Vienna serves as a case study to explore potentials to improve the urban heat supply using waste heat as an additional energy source. As no observation data about waste heat and detailed heating(More)
