Researchers from the University of Oxford's Bodleian Libraries and from universities in the Netherlands have used high-tech imaging to uncover the details of a rare Mexican codex dating from before the colonization of the Americas. The newly revealed codex, or book, has been hidden from view for almost 500 years, concealed beneath a layer of plaster and chalk on the back of a later manuscript known as the Codex Selden, which is housed at the Bodleian Libraries. Scientists have used hyperspectral imaging to reveal pictographic scenes from this remarkable document and have published their findings in the Journal of Archaeological Science: Reports.

Extreme and catastrophic floods in Europe, such as those seen in 2013, currently occur approximately once every 16 years, but this may increase to once every 10 years by 2050, according to new research. The study also suggests that annual average economic losses caused by extreme floods could reach almost five times higher than 2013 values.

Whilst there is interest in bioenergy as a renewable alternative to fossil fuels, there is also concern about its environmental impact. A recent study demonstrates that potential bioenergy crops in Hawaii are 2 to 4 times more likely to be invasive than other plants.

A Dutch study has assessed the water requirements of 13 bioenergy crops across the world. The findings could help select the best crops and locations to produce bioenergy.

A new study has investigated the effects of interbreeding a genetically modified squash crop with its wild relative. The findings demonstrate that it could cause wild or weedy relatives to become more resistant to disease.

A recent EU-supported study has analysed the development of volunteer or ‘rogue’ GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU’s threshold of 0.9 per cent for incidental GM content.

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.

Adverse effects of climate change on agriculture will counteract any improvements in reducing levels of child malnutrition in the developing world, according to a new report, which calculates that twenty-five million more children will face malnutrition by 2050.

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.

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.

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.

Crane fly larvae cause considerable damage to agricultural crops and young trees throughout Europe. New research has demonstrated that certain strains of fungi have significant potential to control crane fly infestations, thus reducing the use of chemical insecticides and enabling more environmentally-friendly strategies for pest control.

Large-scale cultivation of bioenergy crops on marginal land is unfeasible, according to a recent study. While limiting bioenergy crops to less productive land could cut the sector’s impact on food prices, the financial incentive to grow crops on more productive land may be too strong for landowners to ignore, the researchers suggest.

The presence of wild bees alongside honeybees was found to increase almond orchard production in a recent study. The findings demonstrate how increased biodiversity enhances ecosystem services, such as pollination, and provide an opportunity to increase agricultural yields whilst also benefitting wildlife.

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.

'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.

A global cropland percentage map and a global field size map have been created for the first time to guide scientists and policymakers interested in global agricultural modelling and assessment. Both maps are for the baseline year 2005 and combined multiple data sets from global, regional and national levels to achieve a high level of accuracy and 1 km2 resolution.

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.

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.

A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World Health Organization (WHO) warnings.

People exposed to fine particle (PM2.5) and ozone pollution are at increased risk of suffering out-of-hospital cardiac arrests, according to a recent Finnish study. Cardiac arrest is more likely within 24 hours after exposure to PM2.5 and up to several days after exposure to ozone.

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.

A recent study suggests that exposure to aircraft noise during the day has a greater impact on cognitive ability in children than sleep-disruption caused by exposure to aircraft noise during the night. Protective policy is therefore likely to be most effective if focused at the school level.

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.

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.

Ship noise increases shore crabs’ metabolism, a new study suggests. The researchers found that larger crabs were particularly affected by recordings of ship noise in controlled experiments. Increased metabolism is a sign of stress and could potentially reduce the growth of crabs and have implications for their survival, as well as for fisheries.

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.

Exposure to aircraft noise at night for more than 20 years could increase the risk of heart disease and stroke, according to research conducted around six European airports. Risk also increased for those constantly exposed to road traffic, but this may have been caused by air pollution rather than noise.

Recent research into the impact of different levels of noise on 75 volunteers reveals that disturbed sleep caused by night-time aircraft noise can damage blood vessels and increase the levels of stress hormones. As these physical changes are potential pathways to high blood pressure, heart and circulatory disease over the long term, reducing night-time aircraft noise is important for preventing cardiovascular disease in people living near airports.

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.

Climate change could cause increasing but unpredictable hazard risks in mountainous regions, according to a new study. The study analyses the effects of two extreme weather events - the 2003 heatwave and the 2005 flood - on the Eastern European Alps to demonstrate how similar events, predicted to become more frequent under a changing climate, could have an impact on Alpine regions.

Continuing economic development and public health measures are likely to outweigh the impact of climate change on malaria prevalence, according to new research. The research found that the prevalence of malaria has declined over the past century despite rising temperatures.
