Across Europe and the rest of the world, skiing enjoys great popularity. However, it is assumed that the number of ski areas that will remain climatically operable will decrease dramatically in the near future. Accordingly, overcrowding and longer waiting times at ski-lift stations are identified as an economic threat to skiing areas. In this study...

Covid-19 is the first digitally documented pandemic in history, presenting a unique opportunity to learn how to best deal with similar crises in the future. In this study we have carried out a model-based evaluation of the effectiveness of social distancing, using Austria and Slovenia as examples. Whereas the majority of comparable studies have pos...

The exponential character of the recent Covid-19 outbreak requires a change in strategy from containment to mitigation. Meanwhile, most countries apply social distancing with the objective to keep the number of critical cases below the capabilities of the healthcare system. Due to the novelty and rapid spread of the virus, an a priori assessment of...

Millions of people fall ill with malaria every year—most of them are located in sub-Saharan Africa. The weight of the burden of malaria on a society is determined by a complex interplay of environmental and social factors, including poverty, awareness and education, among others. A substantial share of the affected population is characterized by a...

Simulation modeling is increasingly perceived as a methodological asset to the field of data science. Nonetheless, adequate graphical database interfaces are missing especially for most System Dynamics (SD) simulation tools. SimSyn is freely available middleware used to link together models developed in VENSIM with a PostgreSQL database for spannin...

Entities and processes in complex systems are of diverse nature and operate at various spatial and temporal scales. Hybrid agent-based (AB) and system dynamics (SD) models have been suggested to capture the essence of these systems in a natural and computationally efficient way. However, the integration of the equation-based SD and individual-based...

Spatial system dynamics (SSD) models are typically implemented by linking stock variables to raster grids while the use of object representations of human artefacts such as buildings or ownership has been limited. This limitation is addressed by this article, which demonstrates the use of object representations in SSD. The objects are parcels of la...

Computer-based modelling is indispensable to science. Be it in the field of social or environmental science, modelling is used to learn, to gain new insights into behaviours and to raise awareness. In addition to Cellular Automaton and Agent-Based Modelling, System Dynamics (SD) has evolved as an approach which opened up the field of mathematical m...

System dynamics (SD) is an effective approach for helping reveal the temporal behavior of complex systems. Although there have been recent developments in expanding SD to include systems' spatial dependencies, most applications have been restricted to the simulation of diffusion processes; this is especially true for models on structural change (e....

Agricultural production fulfills economic, ecological and structural functions. Despite technological advances, agricultural production remains sensitive to climate variations. In central Europe, climate change is predicted to bring more rainfall in winter, less rainfall in summer, and increased drought risk among other effects. Grassland agricultu...

Recently, the remains of two historic irrigation channels were re-discovered in the Upper Austrian municipality of Regau. Since the current average precipitation in the region is sufficient to sustain a productive agricultural land use, the irrigation channels raise several questions related to climate variability. To verify different hypotheses su...

Due to the expected climate change driven increase of extreme weather events, damage risks for infrastructure and buildings are rising. Hence spatial decision-support material is necessary to enhance risk management and planning strategies. The presented study contributes to this topic by means of an analysis of cloud-to-ground lightning patterns a...

Report of the results of the model region Pinzgau-Pongau within the Alpine-Space-Projekt Climate Change Adaptation by Spatial Planning (CLISP)

The Book describes the main results of the alpine space project CLISP for the model region in Salzburg (Pinzgau and Pongau) and some background informations about climate change in this alpine region.
