| Popis | Long-term increase trend of the human activities has negative impact on the function and landscape stability. Anthropogenic pressure influences directly or indirectly approximately 30 % of the Earth surface. Environmental problems, which are caused by inappropriate land use changes, have adverse effect on human society. This landscape degradation is demonstrated by local predisposition to occurrence of natural risks (flood events, slope instabilities). The transdisciplinary approach was applied on the selected areas in the Czech Republic. Model areas (the Svitava River Catchment, the Leskava Brook Catchment, and the Borovský Brook Catchment) are specific by difference natural conditions and human activities. The research within the GeoRISK project solved identification of landscape level degradation, anthropogenic landforms inventory, ecosystem services evaluation, and uncertainty concept in spatio-temporal data. The main aim of the project is presented by quantitative identification and verification of dependence between landscape degradation and propensity to natural risks formation using geographical analysis and cartographic visualization. One of the main project goals is to identify the most degraded areas, compare them with values of natural risk susceptibility. Observed characteristics are enriched with spatial and thematic uncertainty characteristics to obtaining reliability pattern. The expected project's results confirm high degree of dependence between natural risks predisposition and anthropogenic landscape affect. |
