Satellite observations are valuable aids to detect and monitor fire activity. A recent study has investigated how satellite images of fire activity, together with information on vegetation cover and fire risk associated with long and short-term atmospheric conditions could be used to help authorities better manage the risk of wildfires in Mediterranean Europe.

A major environmental challenge for wastewater treatment is the disposal of excess sludge produced during the process. The LIFE Perbiof project has been developing and testing a technology that will help to overcome this challenge. Results demonstrate it can perform highly effective treatment of municipal wastewater (removing 80% of the organic content) while producing low levels of sludge.

Every year many marine animals including seabirds, sea turtles and sharks are unintentionally caught as bycatch in commercial fishing gear. Recent research has demonstrated that illuminating fishing nets with ultraviolet (UV) lights can reduce sea turtle bycatch without significantly affecting the number of fish caught or their market value.

Recycling offers a promising means of supplying the rare earth elements neodymium and dysprosium, used in computing and low-carbon technologies, research suggests. If recycling infrastructure and technologies are prepared now to deal with the larger volumes of high-tech waste expected in the future, 7-9% of global demand for these critical elements could be met by recycling by the year 2030.

A new tool for minimising offshore wind energy's impacts on other activities in the North Sea has been developed. The tool identifies space for wind farms based on their priority compared to other marine activities, such as sand extraction or fishing.

Which types of buildings will require the least energy for heating and cooling under climate change? A study in Vienna, Austria, looked at the balance between heating and cooling demand in four different types of buildings. The research provides a method that could be useful for other European cities trying to adapt to climate change.

Polarised light forms the basis of many technologies, such as computer monitors. However, current approaches for making polarised light are inefficient, as they produce more than is ultimately used or needed. Researchers may now have found a way to directly produce polarised light using tiny nanostructures, called quantum dots, opening the way for more energy-efficient technologies.

A new study has found evidence for lung toxicity of different forms of ‘cellulose nanocrystals’ (CNCs) in mice. The study suggests that physical characteristics, such as length, of the CNC relates to the type of effect it has on the lung. These nanosized crystals, made from plant-derived materials, are increasingly being used in novel applications, such as cleaning up oil spills in water and flexible electronic displays, and consumer products, which raises concerns about their potential health impacts.

This Thematic Issue provides a flavour of recent work by scientists in the area of biodiversity monitoring to highlight both up-to-date approaches to conservation and evaluation, and how long-term monitoring data could be used more effectively in management and policy decisions.

Wind energy will likely continue to play a leading role in reaching the EU’s renewable energy targets. However, in some areas wind turbines face social opposition based in large part on the visual impact of wind turbines in the landscape. A new study outlines a novel methodology to measure emotional response to wind turbine visuals, which may assist wind farm planners in gauging public acceptance.

Shortages of indium, a key metal found in thin-film solar cells, could limit their large-scale deployment in the future. A new study has outlined four ways that indium supplies could be increased to meet future demand. For example, indium could be extracted more efficiently from zinc ores, or historic wastes containing indium could be processed to extract the element.

Wind and solar energy are effectively limitless resources, but construction of renewable power must compete for a finite amount of land. This study uses a constrained assessment of available land to see whether global energy demand could be fully met by renewable sources. The analysis predicts that by 2070, the world could produce between 730 and 3700 exajoules of electricity per year (EJ/a1) from renewable power, which, even at lowest available land estimates, could meet 2070 electricity needs in most countries.

Cool pavements, which can be used to reduce the Urban Heat Island (UHI) effect, where towns and cities are warmer than surrounding rural areas, have been reviewed in new research. The review found that reflective pavements can reduce temperatures by up to 20°C and are more durable than evaporative pavements, which are less effective at temperature reduction but may have other benefits, such as reducing runoff.

‘Climate-smart agriculture’ aims to sustainably increase agricultural production and increase resilience to climate change. One aspect focuses on climate-smart technologies. This study interviewed users and producers of these technologies, highlighting barriers to adoption and possible means of overcoming them, including increasing awareness, user-focused design and changes to policy.

Wind farms are an important component of Europe’s shift towards a greener energy supply, but they could potentially have an impact on marine ecosystems. This study provides the first measurements of the distribution of harbour seals in relation to the construction and operation of wind farms, and makes recommendations to minimise any potential harm, including breaks in the pile-driving phase of construction.

Electricity consumption fell by 22–27% in low-income households participating in an energy-efficiency programme in Cyprus, France, Malta and Spain, reports a new study. Participants were provided with a range of tools and information to help them curb their energy use, including smart meters and customised reports. The results confirm the value of tailoring information to specific demographic groups.

A new study provides clues as to which innovative low-carbon technologies will successfully get onto the market quickly. The historical analysis of 16 energy technologies — from steam engines to wind power — found that the average length of a product’s ‘formative phase’ is 22 years. This important period of innovation in a technology’s development is shorter for products which do not need extensive new infrastructure or changes to user behaviour. The findings could help policymakers identify new technologies that can be deployed more rapidly to meet short-term environmental targets.

As well as providing renewable energy, wave farms can help protect coasts against erosion by reducing the force of waves. However, it remains unknown whether they can provide this complementary service under future climate change when sea levels will be higher. A new study, based upon computer simulations, concludes that a wave farm off the south coast of Spain could indeed protect the coastline under higher sea levels, and cause the local beach to grow in size after storms.

The international University of California, Riverside-led SpARCS collaboration has discovered four of the most distant clusters of galaxies ever found, as they appeared when the universe was only 4 billion years old. Clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars, as well as hot gas and mysterious dark matter. Spectroscopic observations from the ground using the W. M. Keck Observatory in Hawaii and the Very Large Telescope in Chile confirmed the four candidates to be massive clusters. This sample is now providing the best measurement yet of when and how fast galaxy clusters stop forming stars in the early Universe.

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

The center of the Milky Way galaxy is currently a quiet place where a supermassive black hole slumbers, only occasionally slurping small sips of hydrogen gas. But it wasn't always this way. A new study shows that 6 million years ago, when the first human ancestors known as hominins walked the Earth, our galaxy's core blazed forth furiously. The evidence for this active phase came from a search for the galaxy's missing mass.

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is gusty and turbulent. But near the sun where it originates, this wind is structured in distinct rays, much like a child's simple drawing of the sun. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

The majestic auroras have captivated humans for thousands of years, but their nature -- the fact that the lights are electromagnetic and respond to solar activity -- was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.

A recent report has assessed the latest research on the adverse affects of noise on health, focusing on approaches to estimating the economic cost of noise. This information could help policy makers tasked with designing cost-effective noise reduction and management policies.

Researchers have examined two cases of managed realignment in the UK, whereby coastal areas are deliberately flooded to recreate protective salt marshes. They demonstrated that a sequential decision support system (DSS) can be combined with an ecosystem services approach to provide a robust economic valuation of managed realignment’s benefits. For the case studies analysed, the benefits of managed realignment were found to outweigh costs in the long-term.

Marine litter not only causes environmental damage, but has significant economic costs for industry. A recent study has now estimated that marine litter in the Asia-Pacific region is likely to cost over US$1.26billion per year in damage to marine industries. Policy options for reducing this cost are explored.

Payments for Ecosystem Services (PES) schemes offer direct payments for communities and individuals in exchange for conserving areas of land reserved for conservation for their environmental qualities. The results of an Ecuadorian study highlight key aspects for designing successful PES schemes and demonstrate how investments associated with PES can also benefit poor communities.

However, policies designed to improve ecosystem resilience have met with less success, potentially due to the longer timescales required to see progress in this area. The report concludes that Europe needs new policies and objectives that recognise the links between resource efficiency and ecosystem resilience if it is to move to a sustainable green economy.

Researchers have developed a new approach for identifying regions that are most suitable for expanding ecosystem services. This could be used to help inform spatial planning decisions. By modelling ecosystem services’ opportunity costs in relation to agricultural revenue, the study provides a map of suitable areas of ecosystem service expansion in Eastern Europe.

Following extreme weather events, many countries are unable to afford the costs of providing relief to communities and repairing infrastructure, a new study suggests. The researchers estimate that providing relief on a global scale for events which recur every 10 to 50 years would cost US$3.3 billion (€2.37 billion) annually.

Public support grows for wind farms if they are located away from recreational areas and if they are either fully or partly owned by organisations within the local community. In addition, Swedish consumers would accept bigger bills for electricity generated by wind power if the local population were heavily involved in wind farm planning, a recent survey suggests. This article was updated 30.09.14 to correct an error in the cost of the REC scheme.

Emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) have fallen significantly across Europe since 1960. According to recent research, this is caused by a combination of factors including improved energy efficiency, a changing fuel mix and specific emission control measures. At the same time CO₂ emissions have only increased moderately, mainly due to improvements in energy efficiency.

Seagrass meadows are worth around €78 million every year to commercial fishing in the Mediterranean, a new study estimates. Their annual value to recreational fishing is even bigger, at an estimated €112 million. The researchers say that marine policies should consider the socioeconomic effects of the loss of seagrass, which provides habitat for many fishery species.

In the Mediterranean region the demand for natural resources and ecological services is two and half times greater than ecosystems’ capacity to provide them, recent research has found. To meet this demand, countries rely on imports, exposing themselves to price volatility and potential resource shortages. According to the authors, a 10% increase in global prices would particularly impact vulnerable countries such as Jordan, which would see its trade balance worsening by 2.4% of its gross domestic product.

Global demand for copper could increase by up to 341% by 2050, and energy use is likely to increase with it — rising to a possible 2.4% of global energy demand in 2050, according to new research. Policy actions to avoid such drastic changes could include improving copper recycling and using renewable technologies.

Mental health and supply problems, such as loss of electricity, were perceived by residents as the most serious impacts of 2013 flooding in Germany, according to new research. The most frequent effect of the flooding on companies was interruption to their business. The researchers say that focusing on impacts that can be measured in financial terms does not fully describe the effects of flooding, and make recommendations for improving flood data collection.

Ocean acidification threatens marine ecosystems worldwide, but economic assessments of its impact are lacking. A recent study has predicted the future cost of ocean acidification on mollusc production in Europe and showed that the highest economic impacts would be in France, Italy and Spain. For Europe overall, the annual damage could be in the region of €0.9 billion by 2100.

A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered. Farms in southern Europe are particularly sensitive to climate change and could suffer value losses of up to 9% per 1 °C rise. The researchers say policy, on water and land use, for example, will be crucial to help farmers adapt to climate change and mitigate economic losses.

Agri-environmental measures (AEM) are designed to encourage farmers to protect and enhance the environment on their farmland by paying them for the provision of environmental services. This study suggests that AEM would be more effective if payments were targeted to areas under the greatest environmental pressures, such as intensive agricultural regions — to gain maximum environmental benefits.
