The development of Green Infrastructure (GI) in a UK case study has been researched in a recent study. Some issues caused by an imbalance in stakeholder power and conflicting roles played by major stakeholders were identified with the project. Stakeholder participation is central to the concept of GI and the research reiterates the importance for those implementing GI to ensure that participation is effective and balanced.

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.

Trees form a valuable part of green infrastructure in cities by helping reduce surface water runoff, recent research finds. Together with grassy areas, significant reductions in surface water flows can be achieved by planting trees, reducing the risk of floods.

Two tagged Cuvier's beaked whales have shown intense and lasting avoidance behaviours in response to military sonar. In the first study of this kind, the whales showed significant responses to sonar at volumes that are currently assumed in the US to have no effect on behaviour.

International agreements to reduce plastic use are needed to address plastic litter in the marine environment, as well as increased public awareness of the problem, according to scientists at a workshop on the EU Marine Strategy Framework Directive held in Italy in 2013. The issues discussed at the workshop have been summarised in a recent research paper.

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.

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.

Marine Protected Areas should be managed as integrated networks rather than isolated units because of the high degree of exchange between them, a new study suggests. The researchers found that the large majority of sea bream (Sparidae) and wrasse (Labridae) fish spawned in MPA study sites in the Mediterranean Sea were transported via currents to other MPAs and unprotected areas, highlighting their interconnected nature.

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.

Invasions of alien species are rising at an alarming rate, largely due to growing global trade and transport routes. Preventing the successful establishment of alien species by better understanding the factors determining success is a step toward limiting the threat of future biological invasions. Statistical modelling using observed bird invasion data — including location, event and species-level factors showed which factors were key to successful establishment by the alien species.

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.

The most comprehensive glacier assessment yet reveals that glacier melt was responsible for 27mm of sea level rise between 1961 and 2016. Ice loss from glaciers is now the second biggest contributor to rising sea levels after warming water. If glaciers continue to melt at current rates, most — including many in central Asia, central Europe, western Canada and the USA — will vanish during the second half of this century.

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.

In Sweden, 63% of areas designated as Special Protection Areas (SPAs) for endangered birds are impacted by major roads or train lines, according to a new study. The research showed that 126 000 hectares (ha), or 4.2% of the SPAs, fall within 1 km of a road or train line, leading to a predicted 1% loss in bird abundance. The problem is greater in the south of the country, where 25.8% of land designated as SPA falls within 1 km of a road or rail line, representing an estimated 4 to 7% reduction in birds’ abundance within SPAs.

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

Current knowledge on the availability of mineral resources is explored in a recent study, which focuses on phosphorus as a key example. Static measures of availability, such as the consumption-to-production ratio, are useful as early warning signals, the researchers suggest, but more dynamic indicators that consider technological development and population change are needed to better inform policy.

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.

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.

Increasing resource efficiency is a central aim of European environmental policy, and effective waste management must play a key role in this. A new report assesses waste management in 32 European countries, and identifies key lessons. Landfill taxes and mandatory separate collections of different waste types are highlighted as particularly successful policy instruments.

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.

Scientists in the US have found a way to make a 'biorenewable' plastic from wood by-products. Their fossil fuel-free plastic is similar to polyethylene terephthalate (PET) - a material used to make plastic bottles and packaging. Such green chemistry approaches could help reduce reliance on dwindling fossil fuel resources.

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 recent study has concluded that the green infrastructure concept has been successful in integrating green space policy with economic development policies in the north-west region of the UK, by emphasising the links between the economic benefits of green spaces and growth policies.

Individuals can assess how their behaviour is affecting nitrogen pollution with a newly developed nitrogen footprint calculator, which was developed by a team from the University of Virginia (U.S.) and the Energy Research Centre (ECN, the Netherlands). For many people in wealthy countries, reducing protein consumption to the recommended levels and reducing the amount of red meat and energy they consume would significantly lower their nitrogen footprint.

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.

Increasing the use of recycled materials could substantially reduce the carbon footprint of plastic packaging, research suggests. A new study of the life-cycle of plastic trays has shown that increasing the proportion of recycled material could lead to a significant reduction of greenhouse gas emissions.

Misreported fishing catches in the Baltic Sea have probably led to incorrect fishing quotas, new research suggests. The study found that total catches between 1996 and 2009 have been underestimated for a significant period, skewing quota calculations.

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.

A recent study has investigated how waste disposal sites in southern Italy have affected residents living nearby. Villagers reported being annoyed by odours, but the perceptions of residents living in the village closest to the facilities were possibly influenced by receiving financial compensation for the presence of the facilities.

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.

The views of organisations and industries affected by marine protected areas (MPAs) have been gathered by a new survey. 36 organisations from the UK and France responded to the survey, which asked about the perceived socio-economic and environmental impacts of multiple-use MPAs. Environmental NGOs, managing agencies and research centres gave a largely positive response, while fishers’, shipping, and other industrial organisations perceived an overall negative impact on them. Gathering stakeholders’ views on MPAs may help improve socioeconomic outcomes through informing the planning and management of these marine areas, the researchers say.

The Deepwater Horizon accident raised concerns about the safety of deepwater drilling. From an analysis of risk assessments in the Norwegian Oil & Gas (O&G) Industry, a new study suggests that current safety approaches and indicators are limited and more extensive monitoring of drilling operations is needed to avoid events similar to Deepwater Horizon.

Harbour sediments should be tested for their toxic effects on living organisms in addition to being subject to the chemical, physical and biological tests usually conducted to assess water quality, according to recent research from Portugal. This would provide a better environmental assessment of dredged material to help guide port authorities’ decisions on its disposa

The phrase ‘emerging risk’ has been widely used in scientific and business communities, but without consensus on how to define and govern such a risk. A new study proposes that risk emergence goes through four states, from ‘unknown unknowns’ to risks that are fully in the public domain. Understanding emergence as a process can help decision makers detect and manage risks on the basis of scientific evidence.

Alien plant invasions can have significant environmental, ecosystem and economic implications. Since ornamental horticulture is the primary pathway for invasive alien plant introductions, it is a suitable focus for prevention policies. A recent review of published evidence has examined the effectiveness of four major instruments: pre-border import restrictions, post-border sales bans, industry codes of conduct, and consumer education. The study highlights that, while each instrument has the potential to contribute to a reduction in plant invasion risk, none is sufficient to achieve this goal alone. The researchers, therefore, describe how the four instruments can be integrated along the ornamental horticulture industry supply chain to reduce risk more effectively, and outlines the role that government, industry and other stakeholders must play to achieve this goal.

Paleontologists with the Burke Museum of Natural History and Culture and the University of Washington have discovered a Tyrannosaurus rex, including a very complete skull. The find, which paleontologists estimate to be about 20 percent of the animal, includes vertebrae, ribs, hips and lower jaw bones.
