The Water Framework Directive (WFD) calls for the protection of surface and groundwater. For this purpose, the ten river basin communities in Germany draw up management plans and programmes of measures every six years. The German Environment Agency and the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protec...

This report aims to give a European overview of the main drivers and pressures that are at the core of key water management challenges and which put European water bodies most at risk of not achieving key environmental objectives. Identifying the pressures from and drivers of key water management challenges at the European level can help in priorit...

Key messages: • In 2016, around 50 % of surface water bodies and 25 % of groundwater bodies in the 28 EU Member States and Norway were not achieving good status according to the Water Framework Directive (WFD), in part due to pressures from agriculture. Reducing pressures from agricultural activities is key to achieving good status of all surface...

Pesticides play an important role in the food production process, but they can also lead to harmful effects in the environment. This report provides an overview of the available information on pesticide concentrations in fresh waters and groundwaters in Europe. The report considers data comparable at European level, delivering a detailed summary of...

From the recent reporting of the second river basin management plans under the Water Framework Directive, it is clear that, across Europe, Member States are not achieving at least good ecological status for their water bodies. In particular, this is because pressures from hydromorphology and diffuse pollution affect one third of water bodies in Eur...

The nitrogen pollution of freshwater heavily affects social-ecological systems. To reduce negative effects, research calls for an integrated approach, including a coherent and diverse set of governance instruments. Thus far, however, the effects of (non-)integration have been blurry. Taking Germany as an example, this study sheds light on the actua...

Half of the drinking water consumed in Europe originates from groundwater resources and about one-third from surface waters. EU directives and national legislation should ensure that drinking water is safe and clean, and that drinking water resources will be protected sustainably against anthropogenic forces resulting from extraction, pollution, or...

The main aim of EU water policy is to ensure that a sufficient quantity of good-quality water is available for both people's needs and the environment. The Water Framework Directive (WFD), which came into force in 2000, established a framework for the assessment, management, protection and improvement of the quality of water resources across the EU...

Problem complexity is often assumed to hamper effective environmental policy delivery. However, this claim is hardly substantiated, given the dominance of qualitative small-n designs in environmental governance research. We studied 37 types of contemporary problems defined by German water governance to assess the impact of problem complexity on pol...

Management processes play an important role in helping to achieve the European Water Framework Directive (WFD)’s water quality goals. As a result, researchers have suggested numerous indicators to evaluate the relevant management processes, including indicators that are both generally applicable and highly context-specific. However, these indicator...

Salinity pollution is a global problem but tends to be more severe in arid and semi‐arid regions because of (i) lower dilution capacity of rivers and lakes and (ii) more irrigation areas for agriculture, and therefore, higher total dissolved solids (TDS) loadings from irrigation return flows. The main objective of this study is to analyse potential...

Main messages • Good water quality, together with an adequate quantity of water, are necessary for achieving the Sustainable Development Goals for health, food security and water security. Therefore it is of concern that water pollution has worsened since the 1990s in the majority of rivers in Latin America, Africa and Asia. • It is important that...

Zusammenfassung Die Bewertung von Management-Prozessen ist zentral für die Erklärung der unzureichenden bzw. va-riierenden Erreichung von Wasserbewirtschaftungszielen in den Flussgebietseinheiten (FGEs). Ent-sprechende Indikatoren werden bisher jedoch weitestgehend isoliert dargestellt und empirisch ange-wendet. Basierend auf einem neuen konzeption...

The implementation of the EU-Water Framework Directive (WFD) might also be considered an approach for the implementation of Integrated Water Resources Management in Europe. The WFD outlines the ambitious goal of attaining “good status” for Europe’s rivers, lakes, groundwater bodies and coastal waters by 2015 in accordance with clearly defined time...

Dammed drinking water reservoirs with their catchment areas and the downstream rivers are dynamic systems that change permanently under the influence of many factors. Their multifunctional use for drinking water supply, flood control, energy production, nature conservation and recreation as well as ecological constraints for the rivers downstream r...

The European Water Framework Directive (WFD) was enacted in the year 2000 with a stepwise approach. After legal implementation in the various member states large efforts were undertaken for the initial characterization of water bodies, risk assessment, to implement extensive monitoring schemes and to develop management plans at different aggregatio...

The Water Framework Directive (WFD) sets the ambitious goal of attaining 'good status' for Europe's rivers, lakes, groundwater bodies and coastal waters by 2027 in accordance with a clearly defined timeline. In March 2010 the various EU member states submitted their WFD river basin management plans to the European Commission, which is now checking...

Dammed water reservoirs for drinking water production with their catchment areas and rivers downstream represent dynamic systems that change constantly and are subject to many influences. An optimized management considering and weighing up the various demands on raw water reservoirs (long-term storage for drinking water supply, flood control, ecolo...

Die Nutzungen von Talsperren sind vielfältig, wobei gegenwärtig die Freizeit- und Erholungsnutzung insbesondere in touristisch stark frequentierten Regionen an Bedeutung gewinnt. Daraus ergeben sich vielschichtige Konfliktpotenziale, die integrative Lösungsansätze erfordern. In diesem Beitrag werden am Beispiel der in Nordhessen liegenden Edertalsp...

There is a large variety of uses of reservoirs, but currently leisure and recreation become more and more important, particularly in regions that are popular for tourism. The resulting multilayered conflict potentials require integrative solutions. Exemplified for the Edersee, a reservoir located in the northern part of Hesse (Germany), the aspects...

The understanding about the development of benthic invertebrate communities as a function of abiotic influencing factors in aquatic ecosystems is of essential scientific relevance for the assessment of the ecological status of rivers and streams. For the development of interdependencies between benthic invertebrates, hydromorphology and saprobity,...
