- Malfunctioning soils are specifically problematic in organically cultivated cropping systems, where plants are relying on well functioning soil processes. The here presented experiments aim at describing the effect of degraded soil conditions and compost, green manure or dry mulching based organic amendments on microbial communities associated with the rhizosphere and roots of grapevines. They were performed within the frame of project CORE Organic Plus ReSolVe. Several relationships based on Dice cluster analyses of DGGE gel profiles suggest that fungal and bacterial communities from degraded and non-degraded areas differ. Results also suggest that composted organic amendments and green manure can support the development or enhancement of root associated communities that are different from those in degraded areas. However, diversity indexes did not show that bacterial or fungal communities differed in species number or evenness when degraded and non-degraded plots were compared. With culture dependent methods, a high diversity of Streptomyces spp., best known for their potential to produce antibiotics and increasingly depicted as beneficial plant associated bacteria, were isolated from degraded and non-degraded areas.

- Lake management is extremely complex and requires a coordinated effort of research institutions, community groups, individuals, landowners, and government. Lakes constitute an important group of natural resources due to their ecosystem services and often unique cultural environments. Climate change is a growing concern, which particularly strongly affects shallow lakes. The adverse impact of climate change is enhanced by extreme water level fluctuations and human factors such as environmental pollution from waste water discharge, large scale agriculture and shoreline constructions reducing or eliminating valuable wetlands. Since eutrophication is a leading cause of impairment of freshwater ecosystems, specific strategies to address a lake's nutrient enrichment must focus on activities in the watershed and, if needed, in-lake restoration techniques. Analyzing the key factors of sustainable local and regional development in the vicinity of lakes, assessing the environmental risks of pollution, large scale agriculture, waste management and energy production, we propose a complex, stakeholder based management system and holistic regional development in lake areas, which will preserve natural ecosystems without compromising the sustainable use of ecosystem services. There are available technologies to develop ecologically acceptable water level regulations, promote organic agriculture applying grey water irrigation, stop leachate from landfills and control invasive species. Regional and local production and use of renewable energy is essential both for environmental and economical sustainability. Renewable energy production should be well coordinated with agriculture, forestry, waste management and management of water resources of lakes and their watershed areas in a sustainable, holistic way through a participatory approach. This is particularly pronounced in connection with tourism as one of the main uses of lake-ecosystem services, but also an environmental risk for natural ecosystems when mass tourism and short-sighted profit are the driving forces.
