Persuading the public to reduce bottled water consumption

Despite tap water being freely available and safe in many countries, bottled water is widely consumed around the world. This has negative effects on the environment, including water wastage and pollution. This study assessed beliefs about purchasing bottled water and tested three strategies to change behaviour, showing that combining persuasive information and social pressure can create the most positive intentions to reduce consumption.

Holistic approach needed to reduce consumption of lightweight plastic carrier bags

Reducing plastic carrier bag consumption in different EU Member States requires different approaches and combinations of measures, according to a new study. The authors studied consumption and littering levels across Europe in relation to national plastic bag consumption reduction policy options, and found that there is not one specific solution for both of these factors, nor a single solution that can be used in all Member States. They suggest a holistic approach and additional research into consumer or stakeholder behaviour is needed.

Exploring interlinked drivers of human migration in the context of environmental change

A framework on the effects of environmental change on human migration has been developed by researchers. It makes clear that environmental change can influence migration directly but also indirectly through impacts on economic, social and political factors. The framework can be used to guide further research, evaluate policy options, or develop predictions for migration under global change, say the researchers.

Flood risk from modern agricultural practices can be mitigated with interventions

In the face of substantial evidence that modern land use management practices have increased runoff at the local scale, a new study reveals changes in local land use management practices can reduce the risk of local flooding. However, there is little evidence so far that these local increases in runoff culminate in large-scale flooding effects. To address this lack of evidence, the researchers present a model that maps the downstream rate of flow back to its source areas.

Who should pay for best management practices to reduce soil erosion?

Worsening soil erosion in north-western Europe may be the result of a switch from traditional dairy farming to cash crops. However, even if all dairy farming ceased, reductions in runoff of up to 76% could be achieved if best agricultural practices are employed, at a cost of approximately €45 per hectare for the first three years, new research from the Austreberthe watershed in France suggests.

Environmental conditions in winter can be used to predict European anchovy stock

The European anchovy is one of the most important small pelagic fish in the Adriatic Sea, but the size of the stock can fluctuate year on year. This study aimed to investigate the link between anchovy catch and winter circulation patterns in the North Adriatic sea. The findings show that oceanographic conditions during winter determine anchovy abundance. Prediction of these conditions could help to guide sustainable fisheries management in the region.

Good water quality improvements in the River Seine – but more needs to be done to reduce nitrate pollution

Water policies at European and French national levels have led to a clear improvement in the water quality of the River Seine, a new study has found. A significant reduction in phosphate and ammonium pollution and increasing oxygen concentrations are evident. However, nitrate concentrations are still higher than the recommended level for good freshwater status, despite substantial reductions of surplus nitrogen in agricultural soils over the past few decades. The researchers recommend strengthening current agri-environmental management measures to help the river to return to a fully healthy status.

What makes an urban neighbourhood more resilient to flood? New assessment tool trialled in Hamburg

A method for assessing urban neighbourhoods’ resilience to flooding has been presented in a recent study. The method identifies features of urban landscapes that contribute to three elements of flood resilience: resistance, absorption and recovery. In a German case study, the tool shows that the features which make a waterfront neighbourhood of Hamburg more flood resilient include high bridges, open public spaces and flood-protected basements.

Volume of leachate and environmental impact from landfills reduced — but legacy effects remain

Landfill leachate is the liquid that seeps through or out of waste deposits in landfill sites. EU regulations, such as the Landfill Directive1, have significantly reduced the volume of leachate produced, a study on leachate management in Ireland has found. Leachate, mainly from younger landfills in Ireland is, however, stronger since implementation of the legislation, and the researchers say the future treatment of leachate under stricter environmental protection regulations will continue to be a long-term concern for landfill operators and regulators.

Rapid and significant sea-level rise expected if global warming exceeds 2°C, with global variation

The world could experience the highest ever global sea-level rise in the history of human civilisation if global temperature rises exceed 2 °C, predicts a new study. Under current carbon-emission rates, this temperature rise will occur around the middle of this century, with damaging effects on coastal businesses and ecosystems, while also triggering major human migration from low-lying areas. Global sea-level rise will not be uniform, and will differ for different points of the globe.

Nature-based flood management needs joined-up policy approach to manage benefits and trade-offs

Natural water-retention measures, which ‘keep the rain where it falls’, have great potential to be used as part of flood-risk management plans. But their benefits for downstream urban areas can bring costs to the upstream agricultural areas where they are installed, a recent analysis explains. The researchers behind this analysis suggest that we need new and/or improved policies and institutions to oversee the trade-offs and benefits for agriculture and flood management, and a better scientific understanding of the measures’ likely impact on urban flood risk.

Decentralised supply of recycled water may save energy and reduce greenhouse gas emissions

Reusing waste water for non-drinking uses in decentralised plumbing networks may improve the efficiency of water supply in urban areas, a new study has found. Modelling this approach in San Francisco, researchers found that, depending on the local geography, a decentralised water supply could lead to energy savings and reductions in greenhouse gas emissions from water treatment of around 30%. Improvements in emerging water-treatment technologies are likely to lead to further savings, which could help increase the efficiency of urban water supply.

New tools for improved river assessment and monitoring are likely to inform future management strategies

Sustainable river management is increasingly informed by hydromorphological stream assessments — evaluations and classifications of stream conditions which account for both hydrological (the movement, distribution and quantity of water) and geomorphological (the processes and forms deriving from the interactions of water and sediment movement) features. In order to provide a more accurate and comprehensive assessment of river character and dynamics, scientists have developed three novel methods. Together, these tools represent a promising technique for conducting collaborative assessment and monitoring of river conditions in Europe.

Sustainable urban drainage systems: green roofs and permeable paving compared in southern Italy

A new study has looked at the potential of green infrastructure to compensate for the effects of soil sealing generated by urban development. It investigates how green roofs and permeable paving could contribute to flood mitigation in southern Italy. Using a hydraulic model technique, the researchers found that, in this particular urban case, green roofs were more effective than permeable paving. Policies to promote the adoption of sustainable urban drainage systems (SUDS) by the private sector could thus prove more effective under certain circumstances, and policymakers should look at ways to promote SUDS where suitable.

Sewage treatment plants can do better to close the circular economy loop: resources recovered by only 40% of Italian plants

Scientists have published findings from the largest and broadest survey on sewage resource recovery conducted in Europe to date. Researchers surveyed more than 600 waste-water treatment plants (WWTPs) in Italy, which represent approximately 25% of the country’s total load of treated sewage. The findings provide a comprehensive picture of the current state of sewage resource recovery in WWTPs, revealing that just 40% of plants perform some form of material or energy recovery, and identifying several of the important driving forces behind implementation. This research provides valuable information and insights for policymakers and WWTP managers aiming to improve WWTP sustainability and close the sewage resource-recovery loop.

Food waste: a reduction of up to 50% could reduce EU household expenditure and environmental impact

As the global population increases, it is increasingly urgent that policymakers and other actors facilitate feasible, sustainable solutions to the issue of food waste. This study explored the market effects of reducing household food waste within the EU. The researchers found that reductions of up to 50% by 2030 would lead to household cost savings, a shrinking agri-food sector, a mild negative macroeconomic impact and desirable reductions in environmental pressures, such as greenhouse gas emissions, land use and water abstraction.

River flooding: area simultaneously affected in EU has grown by 50% in past 50 years

River flooding costs billions of euros annually in the EU. When one river floods, others nearby often do so at the same time — extending the overall impact beyond the border of an individual drainage basin. With this in mind, this study analysed the spatial extent of flood events across Europe from 1960 to 2010, using data from the European Flood Database (EFD). The research presents key findings for flood forecasting, risk financing and flood-mitigation policy.
