Farmers in one of Europe’s most water-stressed regions would be willing to pay double the current amount for irrigation water in order to ensure a reliable supply, new research from Spain suggests. The study also shows that they appear unsupportive of new policies proposed by the researchers, such as water markets and tighter controls on groundwater pumping, which could help enable a guaranteed supply of water.

Ireland's national agri-environment scheme can reduce nitrate leaching from beef farming, shows a recent study. Nitrate leached at an average rate of 17.3 kilograms per hectare (kg/ha) on studied plots which complied with the scheme. This compares with 63.1 kg/ha on intensively farmed plots. The programme can therefore help Ireland meet requirements of the EU’s Water Framework Directive (WFD) and Nitrates Directive, the researchers suggest.

Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient run-off that would have affected neighbouring waterways.

The world could experience the highest ever global sea-level rise in the history of human civilisation if global temperature rises exceed 2 °C, predicts a new study. Under current carbon-emission rates, this temperature rise will occur around the middle of this century, with damaging effects on coastal businesses and ecosystems, while also triggering major human migration from low-lying areas. Global sea-level rise will not be uniform, and will differ for different points of the globe.

Researchers have developed a new model that highlights how agricultural practices impact on water availability in the wider landscape. The model, AquaCrop-Hydro, could be used to inform agricultural management decisions and policy related to water and land use, to ensure best allocation of water resources. Such tools are not only useful currently, but will be especially important in future in areas where climate change impacts on water availability and affects crop productivity.

The release of pharmaceutically active compounds (PhACs) in waste water from treatment plants (WWTPs) is currently not regulated anywhere in the world, with the exception of a few plants in Switzerland. Yet thousands of PhACs or their by-products — excreted by humans — can be found in waste water and some of these may harm biodiversity when released into waterways. For example diclofenac and oxazepam may have negative effects on aquatic species.

“We are serving 97% of the pin code across the country, without any delivery charge. We are helping farmers at their doorsteps, just the way urban people benefit from e-commerce shopping”, asserts AK Gupta, Head-IT at IFFCO.

New EU-supported research in the Mediterranean Sea has assessed the impact of fish-farming on seafloor ecosystems. Results indicate that impacts are only apparent in habitats with no vegetation, but the researchers suggest that habitats with vegetation seagrass could be masking the effects.

Planting vegetation to protect coasts from natural disasters, such as tsunamis and cyclones, may damage native ecosystems, according to a new study. As there is also questionable evidence on the effectiveness of these 'bioshields', the study suggested a re-think on coastal vegetation policy and research.

Ponds are considered to be ideal early warning systems that can be used to assess the effects of climate change at the local level. A recent study suggests warmer temperatures are likely to significantly increase the number of species found in ponds in temperate areas, especially at high altitudes. However, despite an overall increase, some species would also become extinct.

Organic farming has often been found to have benefits for biodiversity, but the benefits can depend on the individual species and landscape in question. Research on vine farming in Italy suggests that the impact of organic methods on the number or diversity of pollinating insects may depend on local context. For example, the lack of connectivity between organic vine farms may limit benefits in some circumstances.

New research from the Mediterranean suggests that marine ecosystems are disturbed by the organic food and faeces waste from fish farms, even when the pollutants themselves can no longer be detected. The study recommends calculating an individual pollution 'carrying capacity' for each type of marine habitat, and provides the first published estimate for a ma??rl habitat.

A recent study has examined the effects of different farming practices on bird numbers and species found on farmland during the winter in six European countries. Overall, the greatest number of birds and species were on organic farms, especially when the farms were in landscapes where 80-99 per cent of the land was used for agriculture.

Urban planning policy has had a powerful influence on the amount of green space in cities, according to a recent UK study. It found that a change in planning policy in 2000 led to a decline in urban green space in nine cities between 2001 and 2006, although the amount of green space in all but one of the cities studied has increased overall since 1991.

Setting aside agricultural land remains an important method of promoting biodiversity in Central Europe, according to new Hungarian research. Results have indicated that, compared to winter cereal fields, set-aside land has greater plant and insect diversity. This supports the continuing use of set-aside policy in Central and Eastern Europe.

A recent study has found one means of complementing agricultural production with biodiversity protection by growing seeded ryegrass for silage. The seeds effectively feed many birds, such as the yellowhammer and reed bunting, throughout the winter, and the grass can still be cost-effectively used for silage if it is harvested at the right time.

Intensive farming methods have simplified landscapes across Europe, leading to a loss of biodiversity. A recent study has investigated the effects of intensive farming on plants, beetles and birds in Western European regions and found that plants and birds are particularly affected.

A new study has explored the effects of climate change on Arctic plants by simulating extreme winter warming events and measuring plant responses. The researchers found that considerable damage occurred to dwarf shrub species, in terms of shoot mortality, leaf and root growth.

High Nature Value (HNV) farmland is agricultural land that supports biodiversity and can be identified by its environmentally sound farming practices. New research on bird biodiversity on French HNV farmland has concluded that conservation of HNV farmland is important as well as conserving areas that were previously HNV and have undergone recent agricultural intensification.

The way in which agricultural land is managed can cause environmental changes that affect biodiversity and the services provided by ecosystems. A new study suggests agri-environmental schemes that focus on restoring common weeds, such as thistles, buttercups and clover, could have wide-ranging benefits as these plants appear to help stabilise the supportive links between different species found in farmlands.

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.

Scientists have called for tighter biosecurity measures to reduce the growing threat to biodiversity, food security and ecosystems from fungal infections. Their study reveals that fungal disease outbreaks are on the rise around the world, and will cause further damage unless urgent steps are taken to restrict their unintentional spread through international trade and transport.

Intensive agriculture is widely recognised as a major cause of declining farmland bird populations. New research has identified which aspects of agricultural intensification are most damaging to farmland bird numbers, examining bird populations at seven farmland sites across Europe. The researchers found that simplified landscapes created by intensive agriculture reduced bird numbers at the sites.

It is possible to balance agricultural production with improved biodiversity on farmland, according to researchers. A new study suggests using a combination of land sharing techniques, which enhance biodiversity on existing farmland, with land separation techniques, which designate separate areas for conservation and farmland production.

Leaving land to return to its wild state could be beneficial for abandoned farmland, according to a new study. The researchers argue that 'rewilding' provides valuable ecosystem benefits and in certain cases could be a more achievable goal than maintaining traditional agriculture in areas of Europe where rural populations are declining.

Future decades could see shifts in phytoplankton populations, leading to less diversity among phytoplankton strains in increasingly warm tropical oceans, researchers predict. These microorganisms play an important role in regulating the Earth's climate.

'Bet-hedging' behaviour among farmers, who diversify land use to avoid investing in a single land use that might fail, can boost farmland biodiversity, a new study suggests. However, because historical data show this is not the most frequent strategy used by farmers, balancing environmental and economic concerns in agriculture may still require public policy instruments, such as subsidies or taxes.

The role of wild birds in spreading potentially deadly strains of 'bird flu' is poorly understood. Recent research in Georgia examined an important crossover point of migratory routes, including routes into Europe, and found that only 1% of wild birds tested here carried avian influenza. None of these had the harmful, pathogenic strains.

Research suggests that climate change could alter the structure and function of temperate peat bogs and that these changes are primarily driven by rising temperatures, rather than periods of temporary drought. An average temperature rise above 1??C could permanently shift moss-covered peat bogs into bogs predominately covered with trees, affecting their ability to store carbon and the existing carbon stocks in them.

Using plastic sheeting to encourage early growth of crops reduces the number and diversity of farmland birds, new research from Poland suggests. The study shows that this effect continues even after plastic has been removed.

The value of moving animals or plants from a stable population into one that is endangered or even extinct has been questioned, with some suggesting that it will mean that the new population is not well adapted to its environment. However, research on an endangered toad has shown that even when individuals were translocated from great distances, the population was able to genetically adapt to local conditions within a few generations.

The planned expansion of offshore wind farms in the German Bight of the North Sea will provide hard surfaces in what is currently a soft-bottom habitat. This could see an increase in the numbers of some species, such as mussels, which attach themselves to these hard structures, in turn leading to increased numbers of fish and crabs specialised to this habitat, new research suggests.

Microplastic pollution impairs the heath of the marine worms that help maintain sediments for other creatures, new research suggests. This study shows that the energy reserves of lugworms living in sediment contaminated with microplastic particles were reduced by up to 50%.

New research from central Italy shows that high nature value farmland in the region can be accurately identified by the presence of just four bird species. Once such groups of species have been identified for different regions, they can provide a quick and inexpensive tool for assessing the ecological value of farmland, the researchers say.

A framework to combine economically viable agriculture with effective biodiversity conservation has been described in a recent study. According to the researchers, their approach provides a simple guide designed to help planners and farmers achieve sustainable agriculture.

The pollination benefits of planting field margins with wildflowers can outweigh the costs of set-up and maintenance, a new study suggests. On US blueberry farms wildflower strips resulted in double the number of wild bees on adjacent crops and significantly increased yield, the researchers found.

Monitoring biodiversity on farms is vital for conservation policies but how much does it cost? In a new pan-European study, researchers develop a standardised monitoring programme and estimate it will cost an average of €8 200 per farm to conduct. This cost could be dramatically cut if volunteer ‘citizen scientists’ or farmers help gather data for the programmes.

Two metrics for informing farmers about the biodiversity on their land are presented in a recent Swiss study: average species richness and farm ‘uniqueness’. These are both easy to understand and comparable between farms, the researchers say.

A potential new biopesticide, made of spider venom and snowdrop proteins, kills agricultural pests but shows minimal toxicity to honeybees, new research suggests. Learning and memory of honeybees exposed to the biopesticide were not affected, even at doses higher than they would normally encounter in the environment.

With over half of Europe’s species dependent on agricultural habitats, protecting ‘high nature value’ farmland is vital to biodiversity conservation. However, the identification and assessment of such farmland requires careful co-ordination, concludes a recent study. The researchers present a framework to help with this process and make a set of key recommendations.

The effects of changing agricultural practices on farmland birds are explored in a recently published study from Sweden. Overall abundance of 16 common species declined by 23% between 1994 and 2004, which may be partly caused by changes in land use, such as an increase in the amount of wheat cropland. However, effects vary between species, and some species increased or stayed stable in number.

The biodiversity and abundance of arbuscular mycorrhizal fungi — important soil organisms that can help plants to capture nutrients — is greater in organically managed soils with reduced tilling compared to conventional methods, a new Swiss study suggests. This illustrates the impacts that land management practices such as ploughing can have on soil biodiversity and the ecosystem services it provides.

Rewilding, a process of passive management focused on restoring natural ecological processes and reducing human influence on landscapes, could be used to restore the increasing amounts of abandoned agricultural land in Europe to more biodiverse wilderness. A new study has designed a framework to measure potential for rewilding in areas across Europe, highlighting in particular the potential of Natura 2000 sites and suggesting specific aspects of wilderness that future policies could address.

Insect-eating bats are estimated to be worth US$ 1 billion (€0.91 billion) a year to maize farmers around the world, a new study has revealed. Not only do bats reduce crop damage by eating adult corn earworm crop pests, they also suppress fungal infections in maize ears. Bats and their habitats need to be better protected for their ecological and economic contributions, say the study’s authors.

Ecological intensification, using land and resources in ways that minimises negative ecosystem impacts while maintaining agricultural productivity, has been proposed as a way to sustainably increase crop yields, but remains under debate due to a lack of evidence. This six-year study of a large commercial farm assessed how using land for wildlife habitat affected food crops. The study shows that it is possible to remove up to 8% of land from production and maintain (and in some cases increase) yield.

Conservation of wild plants related to important crops requires more concerted efforts, according to a new study conducted in Scotland. The study makes recommendations for improving conservation within Scotland, as well as outlining a process that could help other countries to prioritise their wild plants.

A new study has assessed community perceptions towards a controversial wind-farm development in Cornwall, UK, following installation. The results indicate that a range of social, economic and environmental factors influence residents’ perceptions of wind farms. Although negative opinions of the wind farm were found both before and after construction, overall, community attitudes towards them became more favourable after construction, adding to evidence that fear of living near wind farms can reduce over time.

Stakeholder support is essential to the success of environmental policies. A recent study has identified stakeholders that can promote biodiversity in European agricultural landscapes. The researchers found farmers were the most influential group of stakeholders, as they make the final decisions on land use. In turn, farmers are influenced in their decisions by a number of actors whose influence is perceived differently on a local and regional level.
