Nanomaterial alternatives assessment: a powerful tool for identifying safer options

DG ENV - Fri, 10/11/2017 - 17:15
Judging whether to replace a hazardous conventional chemical in a product with a nanomaterial — i.e. to assess which is the safer alternative — is challenging for many reasons. A new study suggests that chemical-alternative assessment frameworks could be adapted to better assess engineered nanomaterials with the help of new tools which provide data on hazards of, and exposure to, nanomaterials.

Can supermarkets encourage customers to cut food waste through social media? Analysis of UK campaign shows mixed results

DG ENV - Fri, 10/11/2017 - 17:15
A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

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

DG ENV - Fri, 10/11/2017 - 17:15
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.

More coordinated legislation needed to ensure the Good Environmental Status of European seas

DG ENV - Fri, 10/11/2017 - 17:15
A range of legislation, including the Marine Strategy Framework Directive (MSFD), is designed to ensure the ‘Good Environmental Status’ (GES) of EU seas by 2020. Researchers have assessed the MSFD in relation to existing maritime policies, concluding that coordination between directives is important to achieve GES.

Drivers of renewable energy innovation in the EU

DG ENV - Fri, 10/11/2017 - 17:15
The effects of market regulation and environmental policy on eight types of renewable energy in the EU are identified in a study which examines nearly three decades’ worth of data. The researchers found that reducing entry barriers is a major driver of renewable energy innovation and that the ability of environmental policy to promote renewable energy innovation depends on the technology; for example, quota systems appear to work better with older technologies.

Rejuvenating arid badlands: from barren slopes to living forest in 80 years

DG ENV - Fri, 10/11/2017 - 17:15
A reforestation project has revitalised its surroundings just 80 years after its inception. In the late 1920s, the Saldaña badlands in northern Spain were a barren region, with a thin layer of intensely weathered soil, and only 5% vegetation cover. Now that cover has increased dramatically to 87%, the soil quality is improving, and the water flow in the area has stabilised, bringing greater environmental security to the local community.

Integrating animal and crop production can reduce nutrient leaching from agricultural fields

DG ENV - Fri, 10/11/2017 - 17:15
Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study investigated the impact of ERA on agricultural fields in Finland, showing that the practice can reduce nitrogen leaching and may help to achieve agricultural nitrogen-reduction targets.

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

DG ENV - Fri, 10/11/2017 - 17:15
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.
