Agriculture plays a large role in the management of water in the EU. However, there is little consistent information on water use in irrigation. New EU supported research has estimated how much water is used for irrigation in European countries, providing a framework to analyse agricultural pressures on water quantity.

Climate change poses a large threat to African agriculture, but there is little research on how to respond. A recent study indicates that traditional adaptation methods are not enough and international collaboration is needed in ‘planned adaptation’ by collecting and conserving certain crops for the future.

A recent study investigates the factors that affect a farmer’s decision to convert to organic farming in Latvia and Estonia. A combination of social factors, such as peer pressure, and economic influences, such as subsidies, were found to be more important than either factor individually.

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.

Estonian research has identified land use practices and agrochemical use as the main pressures that are causing a decline in pollinating insects in Europe, such as bees and butterflies. It calls for increased funds for agri-environment measures from the Common Agricultural Policy (CAP) to help tackle pollinator loss.

Researchers have calculated how much phosphorus is taken from the land by major crops around the world and how much is applied as fertiliser, to help estimate agriculture's phosphorus footprint. Among their conclusions, they argue that phosphorus fertiliser needs to be used more sustainably to address global imbalances in its use.

Indonesia’s plans to double palm oil production by 2020 have obvious financial benefits, but implications for food, biodiversity and carbon stocks are not so clear. A new model predicts the impacts of five possible palm oil production strategies and indicates the best approach is to target degraded and agricultural land that is most productive for palm oil.

Organic pesticides may not always be the most environmentally-friendly choice of pest control, according to recent research. Two new synthetic pesticides for controlling aphids were found to be less harmful to other species and more efficient than the two new organic pesticides tested in the study.

A recent study has compared the chemical environmental impacts of using the weed controller glyphosate on glyphosate-tolerant (GT) crops, with the use of other herbicides on non-GT crops. Glyphosate used on GT crops had lower environmental impacts than herbicides used on non-GT crops, but the persistence of AMPA (a break-down product of glyphosate) in soils could be a problem in the future.

Little difference was found between organically grown tomatoes and tomatoes grown conventionally in greenhouses over a three year period, in terms of taste and nutritional value, according to a recent study in the Netherlands. Taste and nutrition were more dependent on the breed of tomato.

Recent research in Italy has suggested that soil quality deteriorates over time when intensively farmed under plastic tunnels. The tunnels are an obstacle to natural rainfall and artificial irrigation increases soil salinity and, as a consequence, agricultural yields can be significantly reduced.

Biochar is increasingly mixed into farm soils to improve crop productivity and maintain carbon stocks. However, it can change the way that pesticides applied to the same soil behave, according to a new study. The researchers suggest that farmers may also need to follow new guidelines on pesticide application if they add biochar to their soil.

Improving the efficiency of milk production could produce significant annual savings and potentially cut the environmental impacts of the industry by up to a third, according to new research from Northwest Spain.

Reindeer herding has a long history in the Arctic, but climate change and industrial activity are bringing this important economic and cultural tradition to breaking point. In a unique initiative, reindeer herders across the Arctic are leading an international team of scientists in using modern technology to adapt to global change and empower indigenous communities.

Natural predators of agricultural pests are influenced by the type and range of habitats within a farming landscape. A new study has developed an approach which predicts the risk of pest infestation and natural predation according to landscape features, to help land managers structure landscapes that encourage natural pest control.

The long-lasting and negative effects of intensive farming on soils persist even where complex animal communities have been reintroduced to the soil in attempt to restore the natural balance, according to a recent study. The findings highlight the possible effects of historical land use on soils' ability to deliver ecosystem services.

There is a need to broaden the debate on sustainable food security from a straight comparison between organic and conventional farming to a consideration of a variety of farming techniques. This is the conclusion of a new review of research that indicates, for some crop types, organic yields can nearly match conventional yields under good management practices and growing conditions.

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.

Although soil quality is best assessed using a wide range of indicators, a smaller set may be more practical and still provide the necessary information needed to choose between land management systems. This is the conclusion of a new study in Brazil that evaluated three different indexes of soil quality based on three sets of indicators.

The widespread use of higher-yielding improved varieties of crops as part of the ‘Green Revolution’ has averted the conversion of between 18 to 27 million hectares of forests, woodlands and pastures in the period 1965 to 2004, according to a recent study. However, its authors caution that the relationship between these crops and land use change is complex, and good governance is needed to protect biodiversity from future expansion of agricultural land.

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.

A new analysis has indicated that policies to encourage active travel, such as walking and cycling, lead to a large but complex range of health benefits. However, it is not always possible to tell which policy has had which specific impact. The study argues for improved approaches to evaluating travel policy that consider indirect policy impacts.

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.

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.

Increasing noise levels are a global environmental concern, and have been linked to important health issues, such as heart disease and cognitive development. New Danish research has now shown that it is also associated with an increased risk of diabetes.

Does scientific evidence always help conflicting stakeholders to reach agreement on how to deal with environmental risks? Scientists have now developed a mathematical framework to help answer this question. They show that stakeholder perceptions of the costs and benefits of regulations, as well as their perceptions of the quality of new research, will determine whether they change their standpoint.

Producing and consuming food has a significant environmental impact. In the search for a sustainable diet, researchers in Sweden explored a method of food production that does not exceed the level of globally available arable land per capita, and involves raising livestock on pasture or by-products not suitable for humans (the ‘ecological leftovers’ principle). The researchers developed three diets based on this method and evaluated their environmental impact compared with current diets.

The application to crops of struvite (magnesium ammonium phosphate) recovered from waste water may cause antibiotic resistance genes (ARGs) present in this fertiliser to enter the food chain. Chinese researchers who conducted this study on Brassica plants suggest that ARGs in struvite pass from the soil into the roots of the plant, and from the roots to the leaves, via the bacterial community already present. The results of this research highlight the need for struvite production methods and agricultural practices that minimise the risk of antibiotic-resistance transmission from struvite to humans or animals via the environment.

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.

Outside the laboratory, living organisms are never subject to single stressors at set doses. In the real world, they face an intricate array of physical, chemical and biological environmental stressors that vary in space and time. The problem of assessing these complex risks for human health and the environment is a great challenge for scientists and regulators alike. For example, even if Maximum Permissible Concentrations (MPCs) for individual contaminants are not exceeded in water, in combination they can still be potentially hazardous to wildlife. This thematic issue reports on scientific research which can help us overcome some of the challenges associated with assessing the combination effects of chemicals.

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.

The Arctic region is home to many unique, diverse and vulnerable ecosystems. But the once pristine Arctic environment is being increasingly affected by human activities. This thematic issue presents the latest research into the impacts of climate change and resource extraction on Arctic biodiversity and indigenous communities.

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.

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.

A new World Health Organisation (WHO) study has estimated that the health impact of environmental noise in western Europe could be up to 1.6 million healthy life years lost annually through ill health, disability or early death.

Surveys have suggested that the public have become more annoyed by aircraft noise over recent decades. A recent study has investigated whether these results are partly caused by changes in survey methods and participants. However, no methodological issues considered could satisfactorily explain the rise in reported levels of annoyance at a given noise exposure level.
