Researchers have discovered high levels of plastic particles and fibres, as well as black carbon (BC), which is formed by the incomplete burning of fossil fuels, in the waters of the Jade Bay, an inshore basin off the coast of Germany in the Southern North Sea. The concentration of suspended particles are of concern because they have the potential to be ingested by fish and other marine life, and enter the food chain.

A new tool to improve the measurement of waste management performance has been presented by a recent study. The researchers applied it to three high consuming cities aspiring to ???zero waste???, finding San Francisco to be closer to achieving zero waste than Stockholm and Adelaide, due to its emphasis on reusing solid waste.

A recent study has revealed how water use has changed across the world over the last 60 years. Growing populations and economic development, particularly in newly-emerging countries, have increased water demand, but technological developments have led to water efficiencies and savings, which moderate these demands.

Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise.

Neither the public nor conservation managers are fully aware of the different risks posed by invasive alien species (IAS), new research suggests. A study examining perceptions of five invasive species in the UK shows that both conservation managers and the public regard some highly damaging species as ???low risk???, and that their awareness does not increase with the amount of scientific research on the topic.

Marine litter is a major issue in deep sea ecosystems in the Mediterranean Sea, new research confirms. A recent study shows that the total weight of litter found in these sensitive areas often equals, and even exceeds, that of the animals that live there. This work can provide a baseline for assessments of the impact of deep sea marine litter and to inform future policy reforms, the researchers suggest.

Tourism businesses operating in protected conservation areas in Europe engage in a high number of sustainable practices, a recent survey of over 900 small-to-medium enterprises (SMEs) reveals. Reasons for their sustainable behaviour include cutting costs, improving company image and lifestyle choices.

Efforts to address climate change and protect natural ecosystems can – and need to – benefit each other. But conflicts can arise. This Future Brief focuses on how land-based ecosystems are affected by wind and solar photovoltaic (PV) development, and how win-win solutions which maximise both conservation and climate benefits may be developed. Recommendations include careful site planning, regeneration and enhancement, and use of multi-level ecosystem data.

The world’s marine ecosystems are at risk of sudden and damaging changes. The authors of a recent study say that co-ordinated management of the many drivers of marine changes, such as overfishing and pollution, is needed across international, national and local scales to help avoid the ‘regime shifts’ that affect ecosystem services and human wellbeing.

Wealthier nations protect biodiversity no better than poorer nations, suggests new research. The study found no link between national GDP and the effectiveness of countries at conserving the species for which they have responsibility.

Damage caused by boats anchoring in seagrass meadows off the coast of Sardinia continues despite restrictions, new research shows. The study's authors provide a number of recommendations to help protect seagrass. These include creating special anchoring areas in seagrass-free locations, and limiting the number of boats that enter a marine protected area.

The number of overexploited or collapsed fish stocks in the Mediterranean Sea has been increasing at a rate of approximately 38 every 10 years between 1970 and 2010, a new study has shown. In the Black Sea, the equivalent figure is 13 stocks per decade, the researchers found. The study’s authors augmented traditional methods of stock assessments with a variety of other data sources on multiple fish species to give a more accurate overview of these marine ecosystems. These results should be used to improve conservation and management, they recommend.

Increases in the amount of CO₂ in the atmosphere can be beneficial to crops, by providing a source of carbon for growth. However, very high levels of CO₂ have the reverse effect, decreasing the yield and quality of vegetable crops, a new study has shown. The researchers say atmospheric CO₂ concentration should be kept below 5 000 ppm to enhance the yield of leafy vegetables such as cabbage and lettuce.

Urban water use increases with a population’s average income, finds a study of a stressed river basin in Spain. Consumption also increases with population age, but falls as education levels rise. Such information could help municipal water providers predict future water trends and to develop appropriate measures by which to manage demand. There is huge interest in mining polymetallic nodules in deep-sea environments. These bumpy rocks on the seafloor contain highly valuable materials including manganese, iron, cobalt, nickel and copper.

In 1989, researchers dragged a plough harrow across the seafloor of the Peru Basin to recreate some of the effects of deep-sea mining. Twenty-six years later, a new team of researchers returned to the site to assess whether there were any long-term ecological effects. They found that the seabed ecosystem remained disrupted, with significantly fewer suspension feeder species, such as anemones and sea sponges, than in undisturbed areas of seafloor. This suggests that deep-sea mining could cause irreversible changes to marine food webs in highly disturbed areas.

A circular economy, in which waste is minimised and resources are kept within the system, relies upon inventive ways of turning waste into a resource. A new study explored the possibility of using the microalga Scenedesmus obliquus to refine and process brewery wastewater. The alga efficiently removed pollutants from the effluent, produced biomass and biofuels in a range of different forms — and with different bioactive compounds — and encouraged waste barley and wheat to germinate at increased rates. This is especially important for breweries, as barley seeds are one of the main feedstocks for the industry — and thus are key to increasing its sustainability and circularity.

Demonstration projects can represent a critical intermediate step between research and development (R&D) and large-scale commercialisation; yet many involving new sustainable technologies fail. In order to map the internal and external factors that enable or prohibit demonstration projects from reaching their goals, a case study of 21 projects was conducted. Qualitative data collected from funding applications and interviews were analysed to identify key themes. Based on these findings, the study proposes a process model outlining the key activities for setting up a new demonstration project.

Approximately 88 megatonnes (Mt) of food are wasted every year in the European Union, causing 186 metric tons (Mt) carbon dioxide equivalent (CO2-eq) — a universal measure for all greenhouse gases. The impact of food waste on the climate, acidification and eutrophication is around 15–16% of the environmental impact of the entire food chain. In developed countries, food waste is high at the point of consumption— so significantly reducing food losses would require a food-waste reduction in households and the food-services sector.

How can we grow more crops without taking too much water away from freshwater ecosystems for irrigation? A new study indicates that it is possible to double crop production by 2050 without exceeding set limits for water extraction if more crops are grown in regions with higher rainfall and with corresponding shifts in international trade and agricultural management. However, without appropriate safeguards, and if we follow the current business-as-usual scenario, this could come at the ecological cost of converting natural land and forest into cropland. This research provides a ‘first-step’ in analysing potential trade-offs in the global food-trade-water nexus.

An early-warning system developed by researchers could help forest managers in Europe predict which trees are at greatest risk of bark- beetle infestation. The study looked at the probability of bark-beetle outbreaks on two important conifer-tree species in Slovenia: the Norway spruce (Picea abies) and silver fir (Abies alba). It found that high temperatures, and extreme weather linked to climate change — including droughts and ice storms — weakened trees, making them more vulnerable to attack by bark beetles.

A new study has investigated the possibility of a regional industrial symbiosis of metal industries across the Sweden-Finland border. The analysis suggests that it is technologically feasible, but that regulatory support may be inefficient, particularly with respect to changing the status of a waste product to a by-product.

A new tool to improve the measurement of waste management performance has been presented by a recent study. The researchers applied it to three high consuming cities aspiring to ‘zero waste’, finding San Francisco to be closer to achieving zero waste than Stockholm and Adelaide, due to its emphasis on reusing solid waste.

The amount of land and ocean that a country uses in order to produce food and other commodities, or its land or ocean ‘footprint’, increases by over a third for each doubling of income, new research shows. Thus, as nations become richer, and lifestyles become more affluent, pressure on natural resources increases.

New research has compared the environmental impact of four alternative methods of water supply in Copenhagen. Results indicated that rain and stormwater harvesting is the most environmentally sound approach, whilst desalination currently has a large environmental impact, mainly due to electricity use. However, if freshwater extraction is included as an impact, the environmental credibility of desalination is improved.

Fish farming in the Mediterranean has increasingly shifted from producing fish such as grey mullet, which are herbivores near the bottom of the food chain, to species such as sea bass, which are predators. This ‘farming up’ the food chain requires wild fish to be caught to provide feed. A return to farming fish lower in the food chain would use marine resources more efficiently, a new study says.

Promoting the personal benefits of sustainable consumption, such as more free time and less stress, could play an important role in encouraging more sustainable living, according to a recent study. The researchers interviewed people who lived greener lifestyles and found that self-interest influenced their decision to consume less and buy sustainable products.

The qualities of sustainable design and the obstacles that Design for Sustainability (DfS) faces are explored by a new study which provides recommendations on how to overcome these challenges. It suggests that design education needs to change and provides advice on how to improve our understanding of consumer behaviour.

As the development of nanomaterials increases, a recent study recommends combining life cycle analysis and risk assessment to improve our understanding of the potential environmental and human health impacts of products containing nanomaterials.

A recent Swiss study compared consumer perceptions of the environmental friendliness of vegetables with the results of scientific assessments of the vegetables’ environmental impact. The two did not always tally and findings from this study can provide useful information for sustainable consumption campaigns.

Rapidly changing fashions increase the production and consumption of textiles and clothing. According to Finnish researchers, more sustainable production and consumption of clothing could be achieved if consumer values are used to rethink design and business strategies. For example, increased personalisation of clothing could increase consumer attachment to products.

A new study has shed light on the sustainable credentials of bio-based plastics. It indicates that, as yet, no bio-based plastics are sustainable, owing to practices including pesticide use. However, this could change with further technological development.

New research has produced a starch-based bioplastic with similar properties to equivalent traditional oil-based plastics. By adding an ammonium salt to thermoplastic starch (TPS) the study demonstrated an improvement in the plasticisation process, rendering it flexible, mouldable and potentially recyclable.

The EU Joint Research Centre has produced a new part of the handbook that provides guidelines for developing and using Life Cycle Assessments (LCA), which evaluate the environmental impacts of products, focusing specifically on life cycle impact assessment (LCIA). It recommends that assessments should be comprehensive, accessible and easy to apply in order to make LCA a more mainstream concept in decision-making.

In a recent experiment in Norway, electrical appliance stores increased their sales of energy-efficient tumble driers when consumers were made aware of their cheaper lifetime operating costs by shop staff and a new product labelling system.

There is a wide range of systems for assessing and communicating the sustainability of buildings, but the variation can be confusing. Recent research has analysed the elements needed for effective assessment and examined the needs of stakeholders to inform the presentation and communication of assessment results.

‘Payment for ecosystem services’ (PES) has become a commonly used term in recent years, yet the concept is not well defined. A new study reviewing PES theory, concepts and practice from around the world provides a valuable overview, concluding that more can be done to share learning.

New research from Sweden identifies the characteristics of substance flow analyses that make them useful to policy makers. Substance flow analyses that focus on measuring rather than modelling pollution and which are aligned to existing measures are more likely to influence policy.

Many citizens living in the countries surrounding the Baltic Sea consider the Sea to be an important recreational area but are concerned about its environmental status, with regard to litter, biodiversity loss, heavy metals and hazardous substances, oil spills and algal blooms. These are the findings of a survey of 9000 citizens, which indicates widespread support for the polluter pays principle to tackle environmental problems in the Baltic Sea.

Researchers have created a new Green Option Matrix (GOM) to describe and compare the ever growing number of options to develop green products and processes. The GOM was used to analyse 142 companies belonging to the Dow Jones Sustainability World Index.

A new study finds that a quarter of fish products labelled as ‘cod’ or ‘haddock’ in Dublin, Ireland, are in fact completely different species of fish. This indicates that fish consumers are being misled by inaccurate labels, which could compromise sustainable fishing and consumption efforts.

A new study from Denmark has indicated that a substantial proportion of farmers may place professional values above cost savings when making decisions about how much pesticide to use. This implies that agricultural policy should consider a broad array of policy instruments to reduce pesticide usage.

Public authorities in EU Member States are encouraged to purchase more environmentally-friendly goods and services through Green Public Procurement (GPP). A recent survey of purchasing managers in Italy has identified some factors that influence their adoption of this strategy, and suggests that a broad knowledge of GPP is key to its implementation.

There is an ongoing debate over exploitation of the Dutch Wadden Sea, over issues including gas extraction and cockle fishing. According to a review analysing interactions between scientists and policymakers during these debates, the productivity of such discussions is substantially influenced by the policy setting, i.e. the level of government involved and the key decision-makers.

Campaigns which remind individuals of the environmentally-friendly actions they already perform may motivate them to even more pro-environmental behaviours, new research suggests. If people identify themselves as environmentally-friendly, they are more likely to carry out green actions, even in the absence of any incentive.

A new tool for mapping the sensitivity of seafloor habitats to fishing activities has been developed. Researchers combined data on the resistance of habitats to damage from fishing practices, and how quickly they are able to recover, to produce a widely applicable tool that can be easily understood by stakeholders and used for different locations.

A new method of assessing human impacts on seafloor habitats suggests that over a third of habitats in the Baltic Sea have an ‘unfavourable’ status. The method is presented in a recent study which concludes that the tool can be effective in helping implement the EU’s Marine Strategy Framework Directive (MSFD).

A new tool to help environmental managers make faster, more evidence-based decisions on how to eradicate alien aquatic species has been developed. The tool is a statistical model based on over 140 management case studies in the scientific literature. Packaged as a user-friendly computer program, it allows different management options to be easily compared.

Public participation in developing coastal management plans can have numerous benefits, such as augmenting expert information with local knowledge and building trust, a new study has confirmed; however, challenges remain, say the researchers. They use the experiences of 10 case studies to make a series of recommendations regarding how to improve the efficiency of the process.
