A circular economy (CE) is one in which materials retain their value and are reused, minimising waste. Cities and councils could act as CE trailblazers by embedding this approach whenever possible into their public purchase of products, services and works. This study explored different approaches to circular public procurement (CPP), and identified possible opportunities to promote CE via appropriate procurement policy and criteria.

Agri-environmental measures (AEM) are designed to encourage farmers to protect and enhance the environment on their farmland by paying them for the provision of environmental services. This study suggests that AEM would be more effective if payments were targeted to areas under the greatest environmental pressures, such as intensive agricultural regions — to gain maximum environmental benefits.

Automation failures have been the cause of such widely reported disasters as the crash of Air France Flight 447 in 2009, with most of the focus placed on deficiencies in the automated system. Although automation does help in avoiding human error in completing tasks, people are still needed to monitor how well the automated system is operating.

New research on a major UK airport (Heathrow) has estimated that a night-time ban on flights could produce up to £860 million (1 billion euros) in financial savings over a 20 year period. Economic costs caused by the ban could be outweighed by savings from reduced health costs of sleep disturbance and stress caused by the noise of night flights.

Car use could be reduced through careful urban planning, according to the results of a new German study. By combining data on driving behaviour and high-resolution satellite imagery, the researchers show how patterns of land and car use are connected.

Carbon emissions from Dutch road networks could be reduced by almost a third if more innovative materials and processes were used, a new study suggests. Researchers assessed the potential benefits associated with 10 innovations in road construction and maintenance, and compared them to conventional materials and processes.

Forests play an important role in both mitigating and adapting to climate change, although current policies tend to isolate the two approaches. A recent study suggests that mitigation and adaptation are complementary and linked, and that forestry management that integrates the two can successfully provide both of these important services.

Tracing products through the supply chain is a key feature for all businesses and industries; this is currently possible via automated identification systems that link a product to a database to track its progress, and through information-tracing (‘infotracing’) systems that keep accessible records of this progress. A study now introduces blockchain technology as a way to electronically trace timber as it travels from the forest to final product, using an infotracing system based on open source and Radio Frequency Identification (RFID) technology that retains records in a secure, decentralised, distributed ledger.

Controlling energy demand instead of supply could help solve the problems of variability associated with wind power, according to new research. In the case of Portugal, it was estimated that measures to reduce electricity demand could reduce the peak consumption by 17.4 per cent in 2020.

According to a new study, an average UK household could reduce its greenhouse gas (GHG) emissions by around 37 per cent through lifestyle changes whilst maintaining an acceptable standard of living.

Despite the contribution that large-scale, intensive agriculture has made to global food production, food shortages still occur with particularly severe consequences for the poor. More investment in locally-led, small-scale farming would help ensure longer-term food security for the world’s most vulnerable under a changing climate and bring environmental benefits, according to a recent analysis of adaptation work in Uganda.

A strategic management tool used to monitor progress towards organisational goals can be adapted to Integrated Coastal Zone Management (ICZM), according to a new study. The researchers adapted the Balanced Scorecard for the Mediterranean region, and suggest that such an approach could be applied to other marine regions.

Policy efforts to decrease energy consumption by improving efficiency may be lessened by rebound effects. New research on household energy consumption indicates just under half EU countries (plus Norway) have rebound effects above 50%, and six are over 100% which means the efforts to increase efficiency backfire, i.e. they increase, rather than reduce, overall household energy consumption. There is a need to think critically about a policy response to the rebound effect and gain a better understanding of why it occurs.

Recycling of excess heat, via ‘district heating’, has the potential to improve energy efficiency in Europe. This study mapped excess heat and demands for heat in EU27 Member States to identify regions suitable for the large-scale implementation of district heating. The authors identified 63 ‘heat synergy regions’, generally large urban zones, which generated almost half of all excess heat generated in the EU27.

Effective regulation of genetically modified organisms (GMOs) calls for monitoring of the potential environmental risks. This study explored whether the German permanent soil monitoring programme could be a useful tool for this purpose. The researchers say the programme has potential to monitor the effects of GMOs on local soil communities, but that adaptations would be necessary.

Research assessments should focus more on engagement processes and less on impacts and outcomes, a new study suggests. The authors examined researchers’ intended impacts and motivational factors, and stated that a change in research evaluation methods, together with better direction from university managers, could help incentivise knowledge exchange and engagement between departments and non-academic entities.

Soil stabilisation and the process of strengthening the physical properties of soil is fundamental to the construction process of infrastructure such as roads, runways and earth dams. Many chemical additives currently used in soil stabilisation are associated with adverse environmental effects and this study examines the use of biopolymers, such as xanthan gum and guar gum, as more sustainable alternatives. The researchers have run a series of laboratory experiments to evaluate the viability of these two types of biopolymers for use as additives for collapsible soil stabilisation, and found that both could be used in place of conventional additives to improve soil strength, permeability and collapse potential.

A study into how agriculture can help humanity meet the United Nations’ Sustainable Development Goals finds that research in Europe on agricultural land systems largely omits key priorities from policy and practice. The researchers identify 32 variables that researchers, policymakers and practitioners collectively prioritise when it comes to European agricultural systems, and suggest that future research includes these in order to more comprehensively analyse trade-offs and identify opportunities for sustainable progress.

A new study has analysed how to reduce the environmental footprint of EU trade by preferentially importing goods from countries that have greener production processes. The study concludes that the environmental impacts of 200 product groups imported into the EU could be considerably reduced in this way. For example, water consumption caused by these imports could be cut by 72%, and land use by 65%.

A more circular economy could reduce global levels of raw material extraction by 10% by 2030, a new study suggests. It could also drive a slight increase in overall employment levels, but the types of jobs available would change significantly, moving away from low- and medium-skilled work in the manufacturing and mining sectors and opening up more opportunities for medium- and high-skilled jobs in the service sector.

Reducing the amount of phosphorus used in agriculture could go a long way in meeting the Baltic Sea Action Plan (BSAP) targets. A Swedish evaluation of measures for reducing agricultural phosphorus suggest phosphorus inputs to the sea could be cut by 180 tonnes per year, or about two-thirds of Sweden's target.

A new solar-powered desalination technology could help solve water shortage problems without any damage to the environment, according to researchers. They evaluated a prototype model and demonstrated that it could produce up to 12 litres of freshwater a day per m2 of equipment.

Confusing water bills and complex water tariffs could be making it more difficult for consumers to monitor and manage their own water use, according to a survey of householders on the Portuguese island of Madeira.

A new study has compared the water governance and management systems of nearly 30 river basins around the world. Results indicated that governance systems with distributed political power and good co-ordination help to implement the principles of good governance in water management practice, and to adopt more advanced climate change adaptation policies.

Flood management could be improved by including socio-demographic information in the assessment of flood risk, suggests new research. The research combined traditional flood risk assessment with information on the ‘social vulnerability’ of people living in flood risk areas. The results show that there are almost twice as many people of high social vulnerability (e.g. low-income or elderly) in flood risk areas of Rotterdam as low social vulnerability people.

Algal (cyanobacterial) blooms are a major threat to marine and freshwater ecosystems, as well as to human health. This study investigated a way to reduce numbers of harmful cyanobacteria using freshwater crustaceans. Data from a large Swedish lake show that this approach can be effective but is best used alongside other methods, such as nutrient reduction.

As the climate becomes more volatile, managing the risk of flooding has never been more important. This study proposes a new framework for evaluating how flood risk is managed by governments, which is applied to reveal the strengths and weaknesses of the system in England. The researchers say their approach can help to improve flood-risk governance and could be applied to other countries as well as other types of hazard.

An innovative system for pricing household water is proposed in a new EU-funded study1 researched in the US and UK. The tariff is designed by combining the economic value of water with reservoir storage data, and is intended to cut water usage during times of shortage by charging large-volume consumers a higher rate which increases as water becomes scarcer. The tariff increase subsidises water for other users, whilst also ensuring the system is economically stable. A case study suggests that the tariff could cut water consumption in the city of Valencia by up to 18%.

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.

As the global population increases, it is increasingly urgent that policymakers and other actors facilitate feasible, sustainable solutions to the issue of food waste. This study explored the market effects of reducing household food waste within the EU. The researchers found that reductions of up to 50% by 2030 would lead to household cost savings, a shrinking agri-food sector, a mild negative macroeconomic impact and desirable reductions in environmental pressures, such as greenhouse gas emissions, land use and water abstraction.

US also marked a slew of issues in India’s digital trade including those in the ecommerce policy.

Old mining sites, such as quarries or pits, could provide refuges for endangered species, according to new research from the Czech Republic. Benefits are greater if the sites are allowed to recover naturally rather than being artificially restored with the use of topsoil, ground-levelling and seed planting.

Mosses are an important but sometimes overlooked group of plants, which play a significant role in cycling in carbon and nitrogen between the land and the air. A new study proposes that scientists could use mosses as a model to investigate the impacts of environmental change on biodiversity and nature.

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.

A new method for mapping long-term changes in habitat over large areas and in fine detail has been developed, which could help inform conservation plans to restore biodiversity to previous states. In a UK case study, researchers have used it to demonstrate the dramatic effects of intensive agriculture and afforestation on rural habitats since the 1930s.

Climate change could alter the species diversity of an important type of polar bacterial community, according to laboratory tests. At temperatures similar to those forecasted using current climate warming rates, researchers observed an increase in toxin-producing bacteria that could alter freshwater polar ecosystems.

A new aerial survey is the first to assess the possible impact of a research station in Antarctica on magnetic fields. Estimations indicated that the station generated a magnetic field that extends up to 650 metres from the station with a peak strength of 2800 nanotesla (nT) within 100 metres from the station on the ground. This may have implications for organisms in Antarctica that are negatively affected by magnetic fields but further research is needed to investigate this.

A recent study sheds light on why some alien species are more likely to become invasive than others. The research in Switzerland found that the alien Spanish slug is better able to survive under changing environmental conditions than the native Black slug, thanks to its robust 'Jack-of-all-trades' nature.

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.

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.

Pollination by wild insects and honey bees improves soybean yield by 18%, new research has indicated. This equates to an extra 331.6 kg of seeds per hectare, boosting the value of the global crop by €12.74 billion. Encouraging insect pollination could therefore reduce the destruction of natural ecosystems to make way for soybean cultivation, the researchers say.

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.

Costs of defending protected areas from poaching and other illegal activities could be reduced through spatial planning software, finds a new study. Using the tool, the researchers devised new patrol activities in central Africa which would reduce current costs of law enforcement by 35%, as well as providing more effective protection.

Citizen science holds the potential to address some of the biggest concerns facing biodiversity researchers, according to a new study. The study found that volunteers already save biodiversity research huge sums of money, but that their contributions are underused.

Urban areas may support higher levels of bee diversity than expected, new research has shown. The UK-wide study compared three different habitat types - nature reserves, farmland, and urban areas - and found a higher number of different bee species in urban areas than farmland. However, the overall pollinator diversity, which included species of bees, flies, hoverflies and butterflies, did not differ significantly between all three landscape types. The researchers call for more attention to be paid to the role of green spaces in cities which can be important habitats for pollinators.

Amid efforts to reduce the loss of global biodiversity, a new study discusses how synergies and trade-offs between different conservation objectives should be researched and recognised in policy making. For example, by increasing protected areas, habitat loss and species decline could also be prevented.

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.

The effect on bats of the replacement of mercury lamps with light-emitting diodes (LEDs) in street lighting has been investigated in a recent study. Artificial light affects bat species differently and the activity of species normally more sensitive to light were affected less by the new LED street lamps than by traditional mercury lamps. Use of LEDs may, therefore, help to reduce the impacts of outdoor lighting on light-sensitive bats, if used at an appropriate level.
