In order to manage its environmental footprint, Switzerland should act on a number of key issues identified by the ‘planetary boundaries’ framework, says a Swiss study, with priority given to the areas of climate change, ocean acidification, biodiversity loss and nitrogen loss. This quantitative framework identifies nine bio-physical limits of the Earth system that, if exceeded, may lead to societal and ecological changes unfavourable to human development and stability. These are upper thresholds rather than targets. The researchers suggest that the concept and their methodology could be used together to think differently about environmental issues, and change the way related assessments and policies are implemented at both global and national levels.

Ahead of the 2016 Paris Agreement on climate change, various climate and energy policy actions were proposed to target pledged 'nationally determined contributions' (NDCs). Now, researchers have quantified the global impact of implementing these actions on air quality, and determined that they have the potential to substantially reduce air pollution worldwide, with significant co-benefits for human health and agriculture — including the prevention of up to 99 000 premature deaths annually by 2030. These co-benefits could offset the global costs of climate policy; this study thus calls for an integrated policy perspective that aims to maximise the benefits of NDCs for climate and health.

Polycyclic aromatic hydrocarbons (PAHs) enter the environment in large quantities via the combustion of fossil fuels and organic matter. They are a cause for concern given their known toxicity, potential to cause cancer and ability to move large distances in the atmosphere — meaning that they are found in remote or protected areas, such as the Arctic, even if not emitted there. This study explores how PAH levels in the Arctic atmosphere have changed over the past 20 years at three sites in Canada, Norway and Finland. The results show that, despite a global decrease in PAH emissions in the same timeframe, the air concentrations in the Arctic are not significantly declining — possibly partly as a result of local warming causing more volatile PAHs to move from the surface to the air.

New pest management strategies may be needed in landscapes where certain types of GM crop are grown, according to recent research. The study found that GM cotton grown in China, designed to resist insect attack, has had an unintended consequence: reduced insecticide use has allowed outbreaks of non-target organisms to infest crops across the agricultural landscape and emerge as new pests.

Risk assessments of potential bird mortality caused by planned wind farms should be assessed at the scale of the individual turbine rather than the whole farm, according to new research. It indicated that risk assessments made prior to building are not predicting the actual level of mortality when the farm is built.

Although methods to assess the impact of genetically modified (GM) crops on terrestrial ecosystems are well defined, impacts on aquatic ecosystems have received less attention. A recent study has shown how the first step of an Environmental Risk Assessment could be applied in an aquatic environment, to assess the exposure of aquatic organisms to proteins in GM crops, using Bt maize as a case study.

A recent analysis highlights the potential of natural products as an indispensable source for drug discovery. Natural compounds can be used directly as potential medicines or can provide templates for the design of synthetic and semi-synthetic drugs. Furthermore, because of their ability to interact selectively with biological macromolecules, they also provide a tool to better understand biochemical processes and thus identify new potential targets for the treatment of human diseases.

It may be possible to use trees to monitor levels of air pollution in cities, new research suggests. A Belgian study found evidence that leaves of urban trees change both chemically and physiologically when exposed to different levels of air pollution. If these changes are carefully quantified, trees could provide cheap and widespread ‘bio-indicators’, the study’s authors suggest.

New low cost methods using bacteria to remove toxic metals from groundwater have been investigated using both actual contaminated groundwater and artificially controlled systems. Environmental conditions, such as changing levels of acidity or alkalinity, can have a significant effect on the removal of toxins, results show.

How can we better anticipate environmental changes? In our rapidly changing world, risks occur from ongoing changes (such as those occurring in the climate), to more sudden-onset risks, such as mutating microbial pathogens. This Future Brief explores some of the tools and approaches that can be used to identify emerging risk, including strategic foresight tools, citizen science and state-of-the-art monitoring technologies.

Traces of animals’ DNA in the environment, known as environmental DNA (eDNA), can be monitored to paint a picture of biodiversity, new research shows. This study used eDNA to assess biodiversity in an entire river catchment in Switzerland. Importantly, the eDNA technique allowed the researchers to detect both aquatic and land-based species in river water, making it possible to assess biodiversity over a broad scale.

Engineering at the nanoscale brings the promise of radical technological development — clean energy, highly effective medicines and space travel. But technology at this scale also brings safety challenges. Nano-sized particles are not inherently more toxic than larger particles, but the effects are complex and vary based on particle properties as well as chemical toxicity. This Report brings together the latest science on environmental safety considerations specific to manufactured nanoscale materials, and some possible implications for policy and research.

Researchers have published a paper providing evidence that a ‘cooling-off effect’ can lead to increased public acceptance of new environmental technologies over time. The scientists analysed survey results from over 1 000 respondents in Germany, using solar radiation management (SRM), a controversial climate-engineering technique, as a test case. They found that, following a cooling-off period of either one month, 12 months, or 18 months, acceptance of SRM increased significantly — and that the longer the cooling-off period, the larger the increase. These findings have far-reaching implications, both for the deployment of SRM and for climate policymakers seeking to more accurately measure the public acceptability of novel interventions.

Conventional municipal waste-water treatment processes are based on aeration, which is energy intensive. Now, researchers have developed an alternative waste-water treatment process. In addition to avoiding the use of aeration in favour of filtration/biofiltration and encapsulated denitrification (the application of capsules containing nitrifiers, which convert ammonium into nitrate), the process also uses waste biosolids to generate electrical energy. The process has been tested in a pilot facility and found to require just 15% of the energy required for conventional approaches. Moreover, the process is energy positive, as the biosolids are able to generate more than enough energy to power the treatment plant. If this technology could be scaled up to the municipal level, it could significantly reduce the energy use and environmental impacts of waste-water treatment.

High-throughput ‘omics’ technologies, which allow exact and synchronised study of thousands of DNA, RNA, proteins and other molecules, are rapidly becoming more advanced and affordable. As these technologies develop, it is becoming quicker, easier and more affordable to generate unprecedented amounts of biological data, much of which could usefully inform environmental management. So far, however, the application of omics information in environmental management has failed to keep pace with the rapid development of omics-based research, meaning there is untapped potential. A recent study highlights the value of bringing omics information into environmental management and outlines practical ways in which omics can contribute to the risk assessment and management of chemicals.

Biodegradable waste, or bio-waste, from urban areas is being used to produce a bio-based material to replace plastic — this is relevant to the sustainable development of a circular economy (CE), which requires the innovative use of waste materials. Understanding public attitudes to such materials, and the drivers influencing their uptake, is key to their viability. This study explores how consumers respond to products made from regenerated bio-waste.
