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.

Removing wheat and sorghum crop residue after harvest, such as stalks, stubble and leaves, may cause more harm than good according to new research. Results indicate that removing residue can increase nutrient and sediment levels in water runoff, and decrease organic carbon stored in the soil.

Global population growth since 1850 has been largely enabled by commercial phosphorus and nitrogen fertilisers. The availability of these nutrients for food production relies upon steadily diminishing resources of natural gas and phosphorus rock. A recent study suggests that to secure a long-term affordable food supply, policy intervention is needed to conserve these essential resources.

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.

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.

Converting grassland to arable land can reduce the diversity of nematodes, predatory mites, earthworms and enchytraeid worms in the soil, according to a study by Dutch researchers. However, they found that restoring arable land to grassland did not fully restore the diversity of these four groups during the course of the four-year study.

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.

Certain vegetables take up heavy metals from contaminated water used for irrigation, a new study finds. The researchers grew vegetables in greenhouses similar to field conditions in Greece and found that concentrations of nickel and chromium increased in potatoes and onions, but not in carrots, when irrigated with water containing contaminant levels similar to those found in industrial wastewater.

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.

'Feed the crop not the soil' is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it.

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.

An extensive field investigation discovered that 38% of soils in southwest England show signs of enhanced surface water runoff due to soil degradation. The study also revealed which types of fields and soils are linked to the most or least degradation.

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.

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.

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.

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.

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.

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.

New research has reviewed the Irish implementation of the first phase of the EU Noise Directive. So far 31 different organisations have been involved and this will increase throughout the second phase of the Directive's implementation. More standardisation is needed to harmonise activities, perhaps by establishing a national expert steering group.

Major roads, railways, airports and industrial areas can be a major source of noise nuisance for local communities. To help city planners and architects determine the most appropriate sound insulation design for the exterior of buildings, Turkish researchers have developed a new method that transforms noise maps into insulation maps.

Noise from underwater geological surveys may be affecting the feeding and social interactions of harbour porpoises, new research has found. The study, conducted off the north-east coast of Scotland, found that the buzz clicks used by porpoises to hunt and socialise were reduced by 15% during the surveys.

Sounds affect our state of mind differently depending on whether they are pleasant or annoying. In a theoretical study, researchers developed a model for exploring human responses to sound. Their work may help us to better understand the health impacts of long-term exposure to noise, as well as the potential benefits of spending time in quiet spaces.

A recent study has analysed risks to European renewable industries from the Chinese supply of critical raw materials. The offshore wind sector was found to be the most vulnerable of the renewable industries to supply risks. EU and industry strategies should be able to deal with these supply risks in the short term, but there are potential long-term risks to solar and wind sectors. The development of alternative technologies less reliant on these raw materials, and methods to recycle these materials is, therefore, a priority.

Upland peat soils provide a substantial carbon sink if managed properly, according to new research. A study of a peatland area in the UK indicated that it could potentially store approximately 160,000 tonnes of CO2 per year.

A recent study in Finland suggests new building regulations will lead to a substantial reduction in the total energy demand and CO2 emissions in new apartment buildings. This could have an impact on the source of energy used for new buildings. In particular, the demand for space heating will fall, which could have an impact on the source of energy used for new buildings.

Heatwaves in Europe are likely to become more frequent and devastating, according to recent research. Climate change will lead to extended periods of high day and night-time temperatures, coupled with high humidity, and will particularly affect the Mediterranean coast and southern European river basins, where there are many densely populated urban areas.

The world’s soils have the potential to store about 3000 megatonnes of carbon per year by the end of the 21st century, according to a new study. It suggests that restoring carbon to cropland and peat soils through practices such as afforestation and no-till farming could help solve global problems of food insecurity and climate change.

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.
