Phosphorus is a major pollutant of surface waters, contributing to poor water quality. A recent study investigated best management practices to reduce the over-application of phosphorus and minimise phosphorus losses from agriculture in four regions across Europe and North America.

A new global study is the first to quantify the potential of water management strategies to increase crop production. It indicates that a combination of harvesting run-off water and reducing evaporation from soil could increase global crop production by 20 per cent.

New research has investigated the long-term effects of applying sewage sludge to Spanish soils. The results indicate that sludge enhances soil properties, but recommends a maximum dose of 40 tons per hectare, applied biannually. Above this level, it appears the soil properties will not improve and may even worsen.

Non-conservative tillage techniques, such as milling and harrowing, are the most common way to manage soil in Mediterranean olive orchards. A new study confirms the value of alternative methods based on the use of spontaneous cover crops which can significantly improve soil structure and reduce erosion whilst maintaining yields.

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.

The health risks to humans of using recycled water to irrigate crops needs to be carefully managed. New research has demonstrated that ???managed aquifer recharge??? can be just as effective as conventional water treatments in improving the quality of recycled water for use in irrigation.

The increasing man-made impacts and effects of climate change are making our coastlines more vulnerable to coastal risks including erosion and flooding. These impacts are far-reaching and are already changing the lives and livelihoods of coastal communities. In addition, they could further threaten valuable ecosystems and damage industries, such as fishing, tourism and shipping. This thematic issue reports on recent research to help guide successful coastal management.

During the last century, large areas of the seafloor have been damaged by human activities such as fishing, sand and gravel extraction and navigational dredging. This Thematic Issue presents quality research exploring the physical damage to the seafloor, new methods for providing seabed information and pressures on marine ecosystems from activities such as deep-sea mining.

Linking land and the sea, coastal zones are unique areas, highly diverse in species, habitats and ecosystems and very important to human activities. But there is a mounting stress on these valuable ecosystems from economic, social and environmental pressures. This Thematic Issue presents key pieces of research that demonstrate tools and experiences for achieving more sustainable coastal ecosystems, and highlights that policy action must continue to strive for significantly improved management.

New research in Spain has explored solutions to reducing traffic noise, and suggests that the best option is to combine global measures, such as speed restrictions, and local measures, such as noise screens.

Companies that adopt the environmental management system ISO 14000, designed to help reduce businesses’ environmental impacts, generally back this up with sincere investment in environmentally-friendly practices, research suggests. Researchers found that adoption of the ISO 14000 was not ‘greenwash’, but reflected a move towards more sustainable practices in both European and North American companies.

Standards for environmental management, such as EMAS and ISO 14001, aim to help organisations become more sustainable, but they have received little evaluation. A new Italian study is the first to quantitatively compare the impacts of these two standards. Its results suggest that EMAS's stipulation that organisations must report their ongoing performance may bring sustained environmental benefits in the longer term.

The factors enabling eco-innovation have been analysed across 19 European countries in a new study. Regulations and environmental subsidies were found to be more important factors in Eastern Europe than in wealthier Western European countries. External research and development (R&D) was also more relevant in Eastern Europe, demonstrating the need for specific technology transfers from other countries and competitors.

Sustainability in the production of goods and services could be encouraged by replacing value-added tax (VAT) with ‘DaVAT,’ a damage and value-added tax, a new study suggests. This tariff is partly based on a life-cycle assessment (LCA) of goods and services and varies from high (products deemed to seriously harm the environment and human health) to low (those with a lesser impact). The researchers propose a novel way to convert VAT into DaVAT and provide a new policy tool, based on LCA, that can be applied by any country wishing to reform its consumption tax system and move towards a more sustainable future.

It is possible to design long-term coastal defence strategies that can be adapted to a range of potential climate change impacts, if prevention measures are considered over larger rather than smaller coastal scales, according to recent research.

Maintaining and restoring the world's drylands or arid zones could provide a win-win option for addressing climate change, according to new research. Drylands not only store large amounts of carbon, but improving how they are managed could reduce the vulnerability of ecosystems and humans.

A Belgian public survey on greener energy consumption has found that positive messages about environmental issues may be more effective than negative messages in encouraging behavioural change for large sections of the public. The researchers suggest this can help policy planners devise targeted communications strategies.

Dire messages about the impact of global warming may increase scepticism because they contradict a commonly held belief that the world is a just and orderly place. This is the conclusion of new psychological research which investigated the reaction of individuals to messages about global warming.

Although the public are largely aware of climate change, their understanding of how they produce and manage carbon is generally not sufficient to lead to changes in behaviour and lifestyle, according to a recent study. The researchers therefore recommend policy action to increase the ‘carbon capability’ of the general public.

Higher atmospheric carbon dioxide levels and temperatures under climate change are likely to increase the rate of corrosive damage in reinforced concrete structures, according to a recent study. This could result in costly repairs in the future, unless structures are suitably adapted.

A UK Government scheme, designed to help finance energy efficiency improvements in the home, has been assessed in a recent study. The researchers advise that better information for homeowners is needed to encourage uptake of the ‘Green Deal’ initiative, and point to Germany’s Passivhaus standard as an aspirational model for green retrofitting.

Over 75 000 regulatory inspection reports for over 32 000 oil and gas production wells drilled in Pennsylvania, US between 2000 and 2012, have been analysed in a recent study. In these reports, the inspectors logged six times as many incidents of damage to the walls of shale gas and oil wells than in wells for conventional oil and gas.

Ocean acidification could damage the organs of Atlantic herring, as well as slow their growth and development, recent experiments show. It adds to the list of pressures currently threatening this commercially important species, including over-fishing and marine pollution.

Ensuring successful public engagement in policy can be difficult. Four key challenges – communicating complexity, providing balanced information, creating space for deliberation and accessing broader values – are highlighted by a new study. Its authors show how they dealt with these challenges in a UK programme, designed to gather public views on the future of national energy policy.

The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening soil moisture conditions in the basin over the course of the century.

How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to minimise the release of methane and nitrous oxide.

Most emissions of nitrous oxide (N2O) are linked to the use of nitrogen (N) fertiliser in agriculture, highlighting a need for agricultural management practices that reduce emissions while maintaining agronomic productivity. A new study has assessed the long-term impact of conventional tillage (CT — where soil is prepared for agriculture via mechanical agitation) and no-tillage (NT) systems on soil N2O emissions and crop productivity in rain-fed Mediterranean conditions. The findings show that, over a period of 18 years, mean yield-scaled (i.e. per unit grain yield) soil N2O emissions (YSNE) were 2.8 to 3.3 times lower under NT than CT. The researchers therefore recommend NT as a suitable strategy by which to balance agricultural productivity with lower soil N2O emissions in rain-fed Mediterranean agroecosystems.

Rapidly rising sales of electronic goods could cause huge amounts of hazardous electronic waste (e-waste) to build up in developing countries over the next 10 years, a new study has concluded. Prompt action is needed to ensure e-waste is properly managed in emerging economies to protect the environment and human health.

Manufacturing solid state lighting (SSL) with light emitting diodes (LEDs) for easy disassembly at end-of-life will facilitate potential end-of-life uses, thereby reducing life cycle costs and environmental impacts, according to a recent study.

Consumers, manufacturers and government all need to take responsibility for managing the increasing number of waste mobile phones, according to new research. Results indicated that levels of copper, lead, arsenic and mercury released through the disposal of waste phones are potentially toxic to health and the environment.

A recent international analysis of waste electrical and electronic equipment (WEEE) management has indicated that current practices will not be able to deal with future increases in WEEE. It calls for rapid, co-ordinated and bold responses that are both technical and non-technical to deal with this ever-increasing global issue.

Waste management policy in the EU is successfully reducing the proportion of waste that is sent to landfill and cutting greenhouse gas (GHG) emissions caused by inefficient waste management, according to a new study. However, the study also supports greater efforts channelled into waste prevention.

Although life cycle assessment (LCA) is a widely accepted method for supporting decision-making, it can face difficulties when being translated into practical life cycle management. A recent case study on local waste management has led to the development of several principles to ensure that LCAs are understandable and applicable.

A recent study has found that improved management of phosphorus in the EU would reduce reliance on imported phosphorus, in addition to reducing damage from excess phosphorus in the environment. This could be achieved through the appropriate use of fertilisers and greater recovery and recycling of phosphorus from all waste sources.

Vastly increasing amounts of waste electrical and electronic equipment (WEEE) are being produced in Europe. Researchers have taken an in-depth look at how Spain has dealt with its electronic waste over recent years, and provide some guidance to other countries developing their own management practices.

Improved public communications and standardised collection systems can greatly increase uptake of safe and sustainable waste electrical and electronic equipment (WEEE) disposal and recycling. This is according to new insights from Italy and Romania, where WEEE collection rates have risen in response to these measures.

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.

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.

Management of waste from construction and demolition sites is a major concern, particularly in urban areas where large volumes of materials are generated. A recent study on the construction and demolition waste (CDW) produced in Lisbon, Portugal, suggests that improved municipal collection systems are needed to reduce the amount of waste ending up in landfill or illegal disposal sites.

Researchers have designed and proposed a new organic waste management plan for Catalonia, Spain, and presented it in a recent study. They say that the plan would reduce a number of environmental impacts that arise from landfilling biodegradable waste, including natural resource depletion, acidification, and eutrophication.

A US-based study has confirmed the prominent position that recycling and personal waste management take in the public consciousness. Crucially, the researchers suggest that understanding the popularity of such waste- management activities could help policymakers promote other forms of pro-environmental behaviour.

Recycling waste from farming and mining could help improve the sustainable use of phosphorus, a recent study suggests. The study traced the stocks and flows of phosphorus over a 50 year period to reveal changing patterns of global phosphorus use. The results can be used to develop the sustainable management of phosphorus — a finite and critical resource — in the future.

A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

A participatory approach to waste management has been tested in Naples, Italy, a city which has experienced ongoing problems with the collection of municipal waste. This study tested a toolkit, which uses stakeholder engagement to improve waste-management decision-making. Residents and other stakeholders supported the use of a technological innovation to develop biomass fuel from municipal waste.

IT advisory IDC estimates that domestic IT spending will decline 4.5% to $55.5 billion this fiscal

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 new tool for flood simulation and visualisation is accessible for both experts and practitioners, allowing them to collaborate better on flood planning and relief. Among other features, the new system includes 3D simulations, rainfall simulation and water flow data.

A new oil-spill risk-management system has been developed by researchers, which shows the likely effects of a coastal spill on the environment and economic activities for specific locations. It provides maps of oil-spill risk through a web portal and could help decision makers and emergency-response authorities protect the local environment and businesses through targeted and efficient planning and responses.
