In Lower Lusatia, eastern Germany, the changing impacts of lignite coal mining and potential climate change have put the naturally low water yield conditions under pressure. Water resources balances describe the hydrological situation in the region and the need for action due to changing boundary conditions. Extended transfer of flood water from neighbouring catchments is considered inevitable for sustainable regional development and the establishment of a quantitatively and qualitatively selfregulated water system. Using the river basin management system WBalMo®, potential water transfer scenarios to compensate for water deficits resulting from regional and global change are analysed.
For decades, water resources have been used intensively for drinking water, industry, agriculture and energy production. This paper summarises the main anthropogenic influences on the water cycle in a Pleistocene landscape and associated geochemical reactions. The results allow the identification and description of the main hydraulic and geochemical processes that control water and solute fluxes in different hydrological compartments, in particular recharge and discharge regions. Under progressive climate change, this process-based knowledge should be used to adapt land and water management to minimise negative impacts on hydrological resources and stabilise the regional water balance in theBerlin-Brandenburg Pleistocene landscape. Based on these results, a risk assessment approach for validation of future management strategies under changing climate conditions is presented.
Over millennia human well-being has benefited from ecosystems, not only through tangible goods, but also through intangible assets known as cultural ecosystem services. Despite growing research over the last decade, cultural services assessment still remains arbitrary and is largely limited to marketable services such as tourism. Evident difficulties in standardizing definitions and measurements have challenged cultural services accounting in decision making processes. However, the imminent formation of the Intergovernmental Platform on Biodiversity and Ecosystem Services offers an opportunity to counterbalance this misrepresentation by establishing a scientific basis for consistently assessing cultural services. In that regard, the current review intends to facilitate discussion investigating the current state of cultural services accounting by offering an appraisal of existing evidence regarding cultural services indicator quality. The current review builds on scientifically recognized frameworks to develop a holistic understanding of how cultural services indicators are conceived within ecosystem services research. Among the measures found, benefit indicators were most frequently used for assessing inspirational, educational and recreational services. A broad variety of methods for accounting cultural services was found, mainly due to the varied aims of the studies. Most of the cultural services indicators were deficient concerning their clarity of definitions, purposes and understanding of the processes to be measured and referring only marginally to tradeoffs and bundles with other services. Only 17% performed multitemporal assessments and 23% used spatially explicit information. It seems that cultural services indicators quality could be greatly enhanced by investing more effort towards involving relevant stakeholders in conceptualization and communication phases, using participatory mapping tools to enhance visibility.
The present study explores whether regional water resources can be used more efficiently by Brandenburg’s farming systems. A description of agriculture in Brandenburg today is followed by a systematic analysis of measures to raise the water efficiency. Brandenburg’s agricultural systems are divided into three sections: soil, plant production and livestock farming. Within these sections measures to increase water efficiency are listed and analysed with reference to five objective criteria for raising water use efficiency. In view of the complexity of farming systems in Brandenburg, general measures to raise water use efficiency could not be derived. Site-specific tillage practices and crop patterns adjusted to recent weather conditions may reflect the specific diversity of Brandenburg more efficiently.
This special issue of DIE ERDE presents selected key topics discussed within the BBAW working group, including work by group members and invited external researchers, containing nine articles highlighting “Regional Water Challenges” resulting from different kinds of environmental and social changes. We aim to present the complexity of interaction between changes and responses. While the first four articles focus on describing climatic and hydrological changes and their causes, the following five articles focus more on possible mitigation and adaptation measures.
