Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season.

New technology that makes energy capture from waste water and re-use of grey water possible can contribute to energy- and resource efficiency — but the widespread application of such technology requires a new, collaborative approach, shows a new study. Taking radical innovation in urban water systems beyond the pilot stage will require cooperation between a variety of stakeholders, suggest the findings of expert interviews and workshops.

A recent study helps city planners find the greenest and most effective way of producing renewable energy, crops and water on rooftops. The researchers developed a method for analysing the performance and environmental impacts of different combinations of rooftop rainwater-harvesting-, energy- and food systems. It could aid efforts to promote urban self-sufficiency and a sustainable circular economy, they suggest.

The NABH Digital Health Standards aims to consider all relevant aspects of the application of patient interfacing technologies across the continuum of care applicable for outpatient, inpatient, and remote patient monitoring.

With close to 450 million Internet users, India is already the largest market for companies like Facebook in terms of users.

Sharad Agarwal, Head-IT at JK Tyre looks at technology as an enabler which will drive productivity and efficiency within the firm.

Grassland bird species of European conservation concern are potentially threatened by changes in land use in the Iberian cereal-steppes. However, a recent study suggests not all bird species respond in the same way to similar management guidelines and agri-environmental schemes need to be adjusted to local conditions.

The success of policy to maintain urban green areas depends on an adequate level of public participation, according to new research. The study compared two twinned European cities with different styles of green space management and found that public involvement may help maintain urban biodiversity.

Pesticides that kill mosquitoes could have indirect effects on other species, according to researchers. The study indicated that a well-known mosquito insecticide led to reduced numbers of eggs and chick survival for house martin birds.

As bee populations decline, exposure of pollinators to pesticides is of increasing concern. Italian research has now demonstrated that an index of exposure which accounts for insect behaviour, as well as pesticide application, provides a valuable tool for assessing the realistic risk of pesticides to pollinators.

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.

Bumblebees are negatively affected by the insecticide azadirachtin even at concentrations 50 times lower than the recommended levels used by farmers, recent laboratory experiments have revealed. No males hatched in laboratory colonies that were fed on recommended levels of the pesticide and, even at concentrations 50 times lower, the males that did hatch were deformed, and there were significantly fewer compared to an untreated colony.

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.

Artificial light — such as street lighting and passing car headlights — has an impact on plants. A new study suggests there could also be broader implications for the interactions of herbivores and pollinators. The study highlights that disrupting seasonal light cues with artificial light has far-reaching effects, including: mismatches in timing with herbivores; altering the development of agricultural crops; inhibiting flowering in wild species; decreasing periods of darkness necessary for plant repair from environmental pollutants; and causing barriers to nocturnal pollinator species.

The importance of seagrass meadows in supporting fisheries has been highlighted by a new study in San Simón Bay, a Natura 2000 site in Spain. The research also demonstrates the benefits of stakeholder involvement in developing management plans to balance conservation with the use of natural resources.

A study of wildflower planting within agri-environment schemes has demonstrated that the practice can support a diverse array of economically beneficial insect species, not just prominent pollinators such as wild bees and hoverflies. The study demonstrates the high conservation potential of wildflower planting within agricultural landscapes and the value of insects outside the traditional focus of conservation efforts.

Isolating specific reasons for involvement in agri-environment schemes (AES) is a key step in the formulation of schemes that are more appealing to Europe’s farming community. Through a comprehensive exploration of the literature on AES across the EU, this study contributes to a better understanding of what drives farmers’ participation in such initiatives, revealing important factors, such as previous experience with schemes and flexibility in management.

A new study has assessed the value of ecosystem-based approaches to mitigating climate changes and conserving biodiversity in Germany. The researchers highlight the trade-offs and synergies between climate adaptation and nature conservation and suggest that effective ecosystem-based climate policy requires improved coordination between different sectors, such as agriculture, forestry and energy.

Ecosystems provide myriad services upon which human societies and economies depend. However, most efforts to quantify and conserve these ecosystem services (ES) focus more on service ‘supply’ (functions which potentially benefit humans) than on ‘demand’ (human desire for that supply). This study maps supply and benefit for three ES — flood mitigation, crop pollination, and nature-based recreation — in the state of Vermont, northeast USA, and finds that efforts to conserve ES could be more efficient if policymakers consider ‘demand’, whilst also decreasing trade-offs with biodiversity protection and conservation.

Considering the impact on soil carbon, biodiversity and ecotoxicity is important when assessing the environmental footprint of dairy products, suggests a new study, which explored the impacts of organic and conventional milk production in three types of system established in Western Europe. The study found that organic milk production had a significantly lower impact on ecotoxicity and biodiversity than conventional milk production, and suggests that including soil carbon changes in the assessment would result in greater reductions in the carbon footprint of organic, rather than conventional, milk — in some cases by up to 18%.

A new study by Swiss researchers has attempted to predict nanomaterial concentrations in the environment. However, the researchers say more data on environmental toxicity are needed before we can make accurate assessments of potential environmental risks from nanomaterials.

Atrazine, a herbicide used globally but banned in the EU, can cause chemical castration and complete feminisation in adult male frogs, according to a recent study. The researchers suggest atrazine could contribute to the global decline of amphibians.

A new study has combined two research methods to assess the risk of pesticide contamination within a river basin and identify locations of risk. Six groups of pesticides were identified in a French river basin and one specific area was labelled as 'high risk' due to intense agriculture.

Long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs) has polluted sediments in high mountain lakes in Europe. Recent research has found that lakes in northeastern Europe are a hotspot for PAH contamination, and concentrations of these toxic compounds were also above the 'no effect' threshold in lakes in north, central, west and southeast Europe.

EU pesticide regulations have encouraged farmers in developing countries to adopt alternative pest management practices and employ safer means of handling pesticides, according to a recent study which investigated green bean farming in Kenya.

A recent study has investigated the effectiveness of the EU concentration limit for Plant Protection Products (i.e., agricultural pesticides) in protecting groundwater ecosystems. For the majority of pesticides, the standard of 0.1 micrograms per litre for each individual pesticide was found to be sufficient, but this may not be the case for some insecticides.

A recent Bulgarian study has proposed a more environmentally friendly approach to manufacturing chemicals and biochemicals in multipurpose batch plants, which carefully considers how the production process is scheduled.

Because natural conditions in the environment, such as temperature, can significantly affect the toxicity of pollutant chemicals on living organisms, the effects of pollutants can differ according to region. Ecological risk assessment should therefore include environmental characteristics relevant to each region, according to recent research.

Pesticides and biocides can cause serious harm to aquatic ecosystems. A study by Swiss researchers has found that the levels of some common biocides entering wastewater and rivers from urban environments are similar to those of pesticides from agricultural land. Although smaller quantities are used in urban areas, similar total amounts escaped into surface waters.

In line with EU legislative requirements, new research has developed models to assess the toxicity of chemicals in terms of their effects on human development. One of the models has been made freely accessible online, so that it is easy to use for industry and regulators.

Many agricultural pesticides used in Europe could disrupt male hormones and lead to infertility problems, according to laboratory tests. ‘Biomonitoring’ studies to investigate the actual behaviour of pesticides in the human body are now urgently needed to clarify the link between pesticide exposure and male reproductive health.

Research in four German rivers indicates that several organic compounds pose a risk of acute toxic effects on invertebrates. Some of these compounds are already priority substances under the EU Water Framework Directive1 (WFD); others could warrant designation at least as river basin specific pollutants in the German River Basin Management Plans.

Researchers have developed new tools to screen previously untested fire-retardant chemicals for potential toxicity. The tools – known as Quantitative Structure-Activity Relationship (QSAR) models – could allow regulatory decisions to be made in the absence of experimental data, saving time and money by prioritising risk assessments for the most hazardous substances.

As bee populations decline, exposure of pollinators to pesticides is of increasing concern. Italian research has now demonstrated that an index of exposure which accounts for insect behaviour, as well as pesticide application, provides a valuable tool for assessing the realistic risk of pesticides to pollinators.

Applying a low voltage to polluted river sediment can boost microbes’ natural ability to degrade harmful polychlorinated biphenyl (PCB) contaminants, according to a new study. The approach could be a cost-effective, sustainable strategy to bioremediate polluted sites.

Changes in complex microbial communities known as ‘biofilms’ at the bottom of rivers can reveal the effects of pesticide and pharmaceutical pollution of river water, according to a recent study. Painkillers and anti-inflammatory drugs were found to have a significant effect on the structure and functioning of the biofilms.

The European ban on atrazine has effectively reduced concentrations of the herbicide in coastal waters, a new study has found. However, the researchers also warn that, in some areas, atrazine levels remain relatively high as some countries have not yet restricted use of the chemical.

Non-target aquatic wildlife species may be more vulnerable to pesticides’ effects, with repeated exposure to low doses over the long-term, if they compete with other species for food, according to a recent study. Understanding how this process occurs can help those undertaking risk assessments and managing pesticides in the natural environment.

Ecotoxicity tests that are used to understand the impacts of chemical pollutants on aquatic organisms and ecosystems could be improved by including all life stages of the test animals. These are the conclusions of a study by Belgian researchers, who found that the apparent absorption of some pesticides by the dormant eggs of water fleas may have negative effects on the invertebrates’ later survival and reproduction, although the development and hatching of the eggs are not affected.

The public places a high value on the use of scientific information, especially regarding climate change, in the management of groundwater resources, a case study in Finland indicates. This suggests that incorporating scientific research into management policies is likely to have the support of stakeholders in the region.

A technique that can detect the array of pesticides bees might be exposed to has been developed in Poland. The simplicity, speed and small sample sizes required for screening makes this technique an improvement over other methods, say the researchers behind its development.

Pollution from agricultural pesticides can present a serious threat to aquatic ecosystems. Researchers have now developed a guide to identify the most appropriate measures to reduce pesticides entering waterways. It focuses on reducing pesticide entry via spray drift or runoff.

The world's first full-scale artificial wetland designed to treat both sewage effluent and mine wastewater has been found to continuously remove high levels of pollutants, a recent study concludes. Treating both types of wastewater at the same time proved to be highly beneficial because they contain pollutants which are more easily removed when mixed together.

Levels of aquaculture pesticides exceed UK environmental quality standards (EQSs) in samples taken from near Norwegian fish farms, a recent study has shown. The researchers examined five pesticides used to kill sea lice (Lepeophtheirus salmonis) and showed that in many cases their concentrations exceeded UK EQSs. They used UK standards, they explain, because there are currently no Norwegian EQSs for these chemicals, and call for international quality standards to be drawn up.

Neonicotinoid and fipronil insecticides have a range of impacts on birds, mammals and fish, a new review of scientific literature has found. A house sparrow would need to eat just one and a half beet seeds treated with a common neonicotinoid to receive a lethal dose, for instance. The insecticides may also have equally important effects on vertebrate wildlife, such as reducing insect prey and hence food supply.

The ability of organisms to adapt to toxic chemicals like pesticides is essential for their survival, but also an agricultural annoyance. This study shows that interactions between different species can delay the development of pesticide resistance and therefore suggests that biodiversity supports effective pest management.

Honeybees and bumblebees prefer feeding on nectar laced with certain neonicotinoid pesticides to uncontaminated food, new research has shown. Far from the predictions of some, that bees would avoid food contaminated with neonicotinoid pesticides if given the choice, a new study has shown that bees did not avoid any of the three most common neonicotinoids: imidacloprid, thiamethoxam or clothianidin. Furthermore, they showed a preference for imidacloprid and thiamethoxam over uncontaminated sugar solutions.

Cereal fields provide a staple food, but are also home to a wide array of invertebrates. This study analysed over 40 years of data to investigate the effects of extreme weather, climate and pesticide use on invertebrates in cereal fields in southern England. As pesticide use had a greater effect on abundance than temperature or rainfall, the authors also recommend reducing pesticide use.
