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.

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.

There is a need for greater harmonisation of the methods used to estimate the environmental impact of products, otherwise known as product category rules (PCRs). A new study has reviewed the development of PCRs and provided recommendations for better alignment.

Using high-strength concrete in construction could help to reduce its impact on the environment, according to a study by French researchers. The researchers compared the environmental impacts of bridges built from ordinary and high-strength concrete and found that the high-strength solution had a lower impact on the environment overall.

Fish farms, and other forms of aquaculture, are seen as a potential solution to meeting increasing global demand for seafood. However, according to recent research, they must reduce their reliance on wild fish for animal feed if current production levels from both aquaculture and wild fisheries are to be maintained.

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.

Hackers have hidden malware in a legitimate two-factor authentication (2FA) app for macOS to distribute Dacls, a remote access trojan associated with the North Korean Lazarus group. [...]

The growing influence of non-governmental organisations (NGOs) in the seafood industry means that they now play a central role in setting standards for sustainable fisheries. In a new study, researchers used the Dutch Good Fish Guide to illustrate how NGOs can efficiently engage consumers, industry, fishermen and government.

People who are committed to reducing their environmental impact at home do not necessarily behave in the same way when on holiday, according to a new study. The study presents a more complex view of consumer environmental behaviour than is often used to inform policymaking.

Standardised methods of categorising environmental data are needed at European and international levels for effective international policies. A recent study has concluded that a European framework that harmonises environmental data at the continental scale corresponds well with national classification systems, although some modifications may be needed to capture small-scale regional variations.

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.

Sustainable management of complex ecosystems requires clear understanding of uncertainty. However, scientific guidance documents show a lack of clarity and coherence regarding uncertainties and tend to focus solely on the need for more data or monitoring, new research indicates. The researchers suggest that scientific guidance should recognise uncertainty as an inherent part of any complex ecosystem.

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 framework to help decide whether to translocate species that are threatened by climate change has been developed. The framework provides a simple method of assessing different strategies and ensuring that limited budgets are used effectively.

An early warning system to predict the overfishing of individual species, far in advance of severe population decline, has been developed by researchers. The ‘eventual threat index’ was applied by the researchers to historical data on tuna and billfish populations, and accurately predicted their current declines as early as the 1950s.

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.

A pan-European survey has revealed the public’s awareness, concerns and priorities about human impacts on the oceans. The results show high levels of concern about marine pollution in particular, and that, generally, respondents were most concerned about the issues they felt most informed about. The study could help policymakers develop marine strategies that are more responsive to public preferences, its authors say.

Simply supplying more scientific information on the environment may not be enough to persuade urban planners to give greater consideration to the environment, suggests new research. The Dutch study suggests that environmental values also need to be made more important to municipal decision makers.

Integrated environmental modelling (IEM) is an organised approach to streamlining the movement of scientific information from its research sources to its application in problem solving, according to a study that envisions a global-scale IEM community. The researchers present a roadmap for the future of IEM, describing issues that could be addressed to develop its potential even further, such as how best to integrate diverse stakeholder perspectives and appropriate guidelines for ‘problem statements’.

A map of science could assist research planning strategies by helping to identify emerging topics. The map — which is based on links to almost 20 million scientific articles that have been published over the past 16 years — clusters and links scientific disciplines by citation-based relationships and serves as a highly detailed and scalable infographic. The authors hope it will be used by research planners to help distinguish — and potentially forecast — the research areas in science which have longevity, and also those which are innovative.

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.

The risk of small or medium oil spills from ships, pipelines, storage facilities and refineries is higher than from oil exploration and production. However, the risk of severe oil spills is highest from exploration and production, according to a recent study. Furthermore, the study suggests that the Deepwater Horizon accident, the largest recorded oil spill, cannot be considered as a particularly rare event.

Sediments collected from coastal Louisiana over a year after the Deepwater Horizon oil spill in the Gulf of Mexico have been found to cause health defects in the Gulf killifish. Nearly all adult fish studied had signs of significantly altered gene function and embryos exposed to polluted sediment were less likely to hatch

Sea level rise may cause soils in coastal regions to become more saline. In a recent study, reproduction in soil invertebrates was impaired in soils containing salt levels below the threshold used currently to define saline soils. The authors recommend community-level studies to further investigate the salt concentrations that are harmful to soil organisms.

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.

A fossil that has been in the collection of the Smithsonian's National Museum of Natural History since it was discovered in 1951 is today helping scientists piece together the evolutionary history of whales and dolphins, including the origins of the endangered South Asian river dolphin.

New Dutch research has investigated the composition and strategies of local activist groups who oppose changes to land use. The results indicated that activists tend to have a higher level of education and live in densely populated areas. They most frequently use awareness-raising strategies, especially when fighting new housing projects.

High quality landscape assessments of areas protected under the Natura 2000 network are critical for effective long-term management plans. In a recent study, scientists have presented a integrated assessment of a Natura 2000 site in Sicily, Italy, which not only considers preservation of environmental features, as required by Natura 2000, but also human features, such as places of historical interest or industrial activity.

As society changes, it places new demands on its surroundings. New research has found that some EU countries are better able to manage the undesirable expansion of cities, the concept known as ‘urban sprawl’, because they have a flexible spatial planning policy that can easily adapt to changes. Urban sprawl is a term used to describe the expansion of residential suburbs around city centres, driven by peoples’ desire to live in larger houses and the ease of transport made possible by cars.

Under pressure from rising food prices, many nations have begun to acquire large tracts of agricultural land in foreign countries, a practice known as ‘land grabbing’. New research has now quantified current levels of land grabbing and demonstrated that it is accompanied by concerning levels of ‘water grabbing’ which could affect water supply in the ‘grabbed’ countries.

Researchers have proposed a new indexing scheme to help decision-makers prioritise brownfield sites for redevelopment. The scheme scores potential sites according to socio-economic, smart growth and environmental dimensions. By giving users the flexibility to emphasise some aspects of development as more important than others, it can be adapted for use in different contexts.

Over 8% of land in Europe could be at moderate-to-high risk of wind-driven soil erosion, a new study has estimated. In the first assessment of its kind, the researchers produced maps which show wind erosion risk across 36 countries. This information could help guide actions to tackle land degradation.

By analysing previous disasters, lessons learnt can be incorporated into policies and plans to manage the effects of future disasters. A recent study examining the 2009 L’Aquila earthquake in Italy suggests that although the national response effectively dealt with the emergency, longer-term measures to help local populations cope with the aftermath of the disaster need to be set out more clearly.

An analysis of flash flood forecasting in Europe has produced recommendations for emergency planners and others to improve flood risk management in vulnerable regions. In particular, the researchers recommend improved data collection and sharing, a common European policy for flash flood forecasting, and that local risk management recognises the specific challenges presented by flash floods.

Researchers have created a simple tool to analyse the risk of river flooding across almost all of Europe, and to estimate the associated economic losses. They found that Eastern Europe, Scandinavia, Austria and the UK are the regions and countries most at threat.

Effective flood-risk communications should include specific information on how householders can protect themselves and their property against flooding, a recent Dutch study concludes. The researchers’ evaluation of communication strategies also highlights an important role for social media in spreading messages about flood risk and protection.

Effective flood-risk management requires accurate risk-analysis models. Conventional analysis approaches, however, are based on the evaluation of spatially homogenous scenarios, which do not account for variation in flooding across a river reach/ region. Since flood events are often spatially heterogeneous (i.e. unevenly distributed), this paves the way for error. Now, scientists have developed a novel framework for risk analysis that accounts for their heterogeneity, and successfully demonstrated the accuracy of the approach by applying it in a proof-of-concept exercise in Vorarlberg, Austria. By facilitating improved prediction and quantification of flood events, this model is likely to inform future flood-risk management and related decision-making.
