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.

Soil erosion is an important issue in Europe, with consequences for water quality, ecosystem services supply and crop production. In this study, researchers enhanced an existing model to estimate soil loss and create an updated map of soil erosion across the EU. The authors say the tool can simulate the effects of land use changes and management practices and will support effective policy decisions.

Adding compost, manure, and other forms of organic matter to farmland soil can boost earthworm numbers, crop yield, and the stability of soil, finds a recent analysis of long-term case studies. No-tillage and crop-rotation practices also have positive effects on soil, although no-tillage's benefits for earthworms are often absent on farms that use herbicides and other pesticides. The study also confirms that organic farming typically produces lower crop yields than conventional farming, but provides recommendations on how to reduce this ‘yield gap’, while highlighting positive aspects of organic agriculture.

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.

Widespread use of antibiotics to prevent and treat infections in people and animals as well as for promoting growth in livestock is causing environmental contamination. A new study highlights the need for extra measures to reduce environmental pollution from antibiotics. Such pollution can increase the risk of diseases caused by bacteria that become resistant to antibiotics.

Monitoring the effects of chemicals in the human body provides useful data for assessing and managing environmental risks to health, but it also raises ethical questions about how the results of such studies should be reported to participants. New research suggests that changes are needed to the research process to allow study participants to play a greater role in interpreting, disseminating and using the results.

The Global Allergy and Asthma European Network (GA2LEN), established in 2005 to facilitate excellence in allergy research across clinical and research institutions in Europe, has recently published a report on its major achievements.

The number and impacts of disasters have increased in Europe in the period 1998-2009, a new report by the European Environment Agency (EEA) concludes. The report assesses the frequency of disasters and their impacts on humans, the economy and ecosystems and calls for better integrated risk management across Europe.

A recent study has investigated how exposure to a variety of environmental pollutants, including heavy metals and chlorinated compounds, affects the height and body mass index (BMI) of local communities. It found that some pollutants could be causing reduced height and BMI, which can be explained in part by the pollutants??? disrupting effects on the hormonal system.

Contrary to some established views, the local animal population is unlikely to be the major source of resistance diversity for Salmonella Typhimurium DT104 in humans in Scotland, according to a study. The researchers suggest that a broader approach to fighting antibiotic resistance is needed, which goes beyond focusing solely on curbing the use of antibiotics in domestic animal populations.

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.

Pollen allergy is a common cause of allergic respiratory diseases such as hay fever and asthma. A recent continent-wide study suggests that rising carbon dioxide (CO2) emissions over the last 30 years may be increasing pollen counts especially in European cities, which could have serious consequences for public health.

In the aftermath of natural disasters, displaced communities require temporary accommodation. A new study has examined how the built environment of these temporary communities influences their recovery and resilience, using accommodation set up after Hurricane Katrina as a case study. It highlights the importance of developing transitional built environments that consider the social and mental health needs of a community.

A recent pan-European study has reviewed the factors which influence how annoyed a person feels about road traffic and aircraft noise. Among its findings, residents in terraced housing or apartments were less annoyed by road traffic noise than residents in semi-detached or detached housing.

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.

The worldwide decline of pollinators could increase cases of vitamin and micronutrient deficiencies in humans, new research suggests. For instance, pollination is needed for the crops that produce half of all plant-derived vitamin A across much of south-east Asia. Furthermore, areas which depend most on pollination for micronutrient supply tend to be poorer and already at higher risk of deficiencies.

Dry soils and a lack of cloud cover help explain a major heatwave in France, concludes new research. The study indicates that the two drivers were separate, unlinked events that came together at the same time to worsen the 2006 heatwave. Its findings could allow heatwaves to be predicted more accurately to protect public health.

For people in the UK to eat the recommended 280 grams of fish per week, the country would have to rely on aquaculture and increasingly on imports of both wild and farmed fish from poorer countries, a recent study has revealed. This can have social and environmental implications and the researchers urge governments, particularly in developed countries, to consider nutritional advice in a global context, to minimise the impact of fish exports from poorer countries.

Scientists have measured how children and pregnant women are exposed to over 120 environmental factors influencing our health — from air and noise pollution to green space and access to public transport. The study gathered and analysed data from six European countries to build a picture of the ‘exposome’ — the array of environmental factors that humans are exposed to from the moment they are conceived. A better understanding of the exposome could help us understand the role of the environment in the onset of various diseases, including cancer and other chronic disorders such as cardiovascular disease.

The presence of plastics in aquatic environments is a growing concern across the EU. This study explored the amount of microplastic particles present in raw and treated water at three water-treatment plants in the Czech Republic. While treated water contained fewer particles than raw1 fresh water, the amount found in treated water was not negligible, and largely comprised tiny particles of <10 micrometres (μm) in diameter. Ways to filter microplastics from potable water must be identified and their risk to humans, sources and routes into drinking water determined, say the researchers.

Research into ecosystem services has flourished considerably since the publication of UNEP's Millennium Ecosystem Assessment in 2005, notably the ongoing Economics of Ecosystems and Biodiversity (TEEB) project, which is making a compelling case for promoting conservation by estimating the economic benefits of ecosystems to human welfare and the economic cost to society of ecosystem decline. This thematic issue provides a snapshot of the latest research in the most recent chapter of ecosystem services' story. It aims to help guide future conservation and sustainable development policies.

Policy measures to protect biodiversity must be scientifically sound in order to deal with the complexity of nature and the human pressures on nature. This thematic issue reports on research which can help policy makers understand biodiversity in water and different ways in which human activity can be managed to ensure both wildlife and humans benefit from healthy aquatic and marine ecosystems.

The current economic and environmental crisis tells us that the time is ripe for governments around the world to implement a new kind of economy, which is resilient, sustainable, operates within the limits of our planet's resources and creates a fairer society. This thematic issue covers research which can help policy makers develop this Global Green Economy.

Humanity is demanding ever greater economic productivity at a time when natural resources, the input that feeds this productivity, are dwindling. To reduce pressure on key assets, such as water, minerals, fuel and land, we must use less of them, and we need to increase the efficiency and productivity of resources that we do use, to achieve more output per input. Put simply, we must do more with less. This thematic issue reports on research which helps guide the way to a more resource efficient society.

Biodiversity and ecosystems provide many critical life support functions and benefits for human wellbeing, security and economic growth, including food, clean water, recreational services and climate regulation. Despite its significant values, biodiversity worldwide is being lost, in some areas at a rapid rate. Given these losses, there is an urgent need for firstly, greater application of policies and incentives to promote the conservation and sustainable use of biodiversity and ecosystem services, and secondly, a more efficient use of available finance in existing biodiversity programmes. PES is a flexible, incentive-based mechanism that has potential to deliver in both of these areas. This Thematic Issue of Science for Environment Policy explores research which can help guide effective Payments for Ecosystem Services (PES) schemes. Under PES agreements, a user or beneficiary of an ecosystem service provides payments to individuals or communities whose management decisions and practices influence the provision of ecosystem services.

To meet demand, more and more water is being abstracted from the land and transported long distances. This thematic issue addresses the most pressing policy issues within this field as Europe looks for an effective strategy to deal with water supply and consumption.

This Thematic Issue reports on research into policy targets for sustainability, and associated indicators, to tie in with the launch of the EU's 7th Environmental Action Programme.

Brownfield regeneration and land use planning are complex issues which encompass many different environmental, economic and social dimensions. This Thematic Issue brings together quality research into brownfield regeneration, which highlights insights and successful strategies from across Europe and beyond.

Exposure to excessive noise is recognised as a major environmental health concern. This Thematic Issue examines the impact of noise on human health and outlines how policy initiatives may limit health effects from noise annoyance - and improve wellbeing.

Nanomaterials – at a scale of one thousand times smaller than a millimetre – offer the promise of radical technological development. Many of these will improve our quality of life, and develop our economies, but all will be measured against the overarching principle that we do not make some error, and harm ourselves and our environment by exposure to new forms of hazard. This Thematic Issue explores recent developments in nanomaterials research, and possibilities for safe, practical and resource-efficient applications.

Energy efficiency is at the centre of EU policy for achieving a fundamental transformation of Europe’s energy systems by 2030. This Thematic Issue reveals the complexity of the issue of energy efficiency, its links with resource efficiency and the wide range of factors influencing it, from technology to social practices.

Important factors in the creation and maintenance of effective Environmental Enforcement Networks (EENs) have been shared by the International Network on Environment Compliance and Enforcement (INECE), one of the first EENs to emerge. By disseminating these ‘lessons learned’ the INECE hopes to facilitate the creation of effective EENs in emerging networks, such as those in Eastern Africa, Western Africa and South America.
