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.

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.

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.

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.

Local food systems, such as vegetable box schemes or farmers' markets, can encourage sustainable consumption. However, authorities must take care before becoming too involved in such citizen-led initiatives, because these collectives may be wary of government intervention, a new study suggests.

Effective ‘knowledge exchange’ - the process of producing, sharing, understanding and using knowledge - is vital to good environmental management. New research has uncovered five principles for this process which could help researchers, decision makers and other parties work together to better manage environmental change.

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.

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.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

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

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.

Researchers are on a real-life search for what one calls "the ultimate Pokémon": Zenkerella, an elusive scaly-tailed squirrel that has never been spotted alive by scientists. However, biologists recently found three newly dead specimens that hint at how the "living fossil" has evolved over the past 49 million years.

A Bosnian pine (Pinus heldreichii) growing in the highlands of northern Greece has been dendrocronologically dated to be more than 1075 years old. This makes it currently the oldest known living tree in Europe. The millenium old pine was discovered by scientists from Stockholm University (Sweden), the University of Mainz (Germany) and the University of Arizona (USA).

Geography and ecology are key factors that have influenced the genetic makeup of human groups in southern Africa, according to new research discussed in the journal GENETICS, a publication of the Genetics Society of America. By investigating the ancestries of twenty-two KhoeSan groups, including new samples from the Nama and the ≠Khomani, researchers conclude that the genetic clustering of southern African populations is closely tied to the ecogeography of the Kalahari Desert region.

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.

Even small areas of semi-natural vegetation, farmlands and abandoned farmlands provide important ecosystem services in urban environments. However, there is widespread loss of these non-urbanised areas (NUAs) owing to poor planning and urban sprawl. A new five-step process has now been developed that can inform effective planning to protect and enhance the value of urban green spaces.

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.

Comprehensive flood risk management should include household measures, such as improving a home’s stability and relocating heating systems to safe places within the house. According to new research, better communication with householders by authorities on the effectiveness of such measures, and how to implement them, could increase their uptake.

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.

A team of researchers from Florida State University, Johns Hopkins University and the National Institutes of Health has found existing drug compounds that can both stop Zika from replicating in the body and from damaging the crucial fetal brain cells that lead to birth defects in newborns.

Whilst there is interest in bioenergy as a renewable alternative to fossil fuels, there is also concern about its environmental impact. A recent study demonstrates that potential bioenergy crops in Hawaii are 2 to 4 times more likely to be invasive than other plants.

Reducing meat and dairy consumption would help reduce greenhouse gas (GHG) emissions from farming. A recent study describes the "ecological leftovers" approach to reducing livestock-related GHGs, which assumes that a sustainable number of livestock can be calculated on the basis of available marginal land, unsuitable for other purposes, and available agricultural by-products, which could be used as feed.

Scientists have identified several wild insects that could undertake the crop pollination function of honeybees. By comparing a range of pollinating insects they found three wild species that appear to be as efficient as the honeybee in pollination but may need management to increase their numbers.

New research in southern Spain has studied what influences participation in agri-environmental schemes (AES). It indicated that the uptake of schemes that involve a major change in farm practices depends on the farm structure, whereas for schemes with minor changes, individual farmer characteristics play a greater role.

A new combination of three models has explored the future dynamics of European livestock distribution. The results indicate that, without environmental policy, livestock density will increase both inside and outside current livestock hotspots. This will also occur to a certain degree with regulation, but the risk of negative impacts will be less likely.

Sustainable food production in developing countries can be achieved through ‘agroecology’ – where farming practices mimic nature rather than relying on external products, such as fertilisers and pesticides. This is according to a recent report, which claims that conventional farming does little to alleviate rural poverty and ecosystem degradation.

Large-scale cultivation of bioenergy crops on marginal land is unfeasible, according to a recent study. While limiting bioenergy crops to less productive land could cut the sector’s impact on food prices, the financial incentive to grow crops on more productive land may be too strong for landowners to ignore, the researchers suggest.

Storage of carbon in soil helps to keep land fertile and regulates the climate, and is therefore an important ecosystem service. However, mapping of soil carbon stocks currently uses unreliable measures. This study used data from a national survey of English grasslands to show that soil carbon stocks can be accurately predicted using simple measures of soil and climatic conditions.

A global cropland percentage map and a global field size map have been created for the first time to guide scientists and policymakers interested in global agricultural modelling and assessment. Both maps are for the baseline year 2005 and combined multiple data sets from global, regional and national levels to achieve a high level of accuracy and 1 km2 resolution.

Crop rotation is gaining increasing research- and policy attention as an environmentally friendly way to manage weeds. In such rotations, crops are introduced that release chemicals into the environment known to inhibit weed germination or growth (so-called allelopathic crops). Previous studies have identified Cynara cardunculus L., a perennial thistle, including varieties of globe artichoke and cardoon, as a potential allelopathic candidate. This study conducted field experiments using three botanical varieties of C. cardunculus to evaluate their effect on weeds within an ecosystem. The results confirm that C. cardunculus has an allelopathic effect in monoculture, reducing the amount of weed seeds present in soil. This paves the way for its inclusion in crop rotation as part of eco-friendly, sustainable weed-management strategies.
