Indium, a unique metal, is in short supply worldwide and is not recycled at the end of its life (EoL). Indium is used in a wide range of technologies, causing regions across the world that are reliant on its import — such as Europe — to be concerned about security of supply. Primary sources of indium are thought to be sufficient for medium-term needs, but with growing demand comes growing concern over long-term supply. A new study has conducted a material flow analysis and examined secondary sources of indium within European ‘urban mines’ and in-use stocks (IUS) of indium products, identifying these as potential sources of 500 tonnes of indium — if it were recycled at EoL.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) surveyed dozens of young stars -- some Sun-like and others approximately double that size -- and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks. In contrast, the lower-mass, Sun-like stars have debris disks that are virtually gas-free.

Valuations of water quality as an ecosystem service often fail to include related services like recreation or human health, and do not consider the effects of water quality changes due to management. Researchers have now developed a template for valuation that considers multiple services and links management actions to changes in water quality and ultimate economic value.

Bee pollination improves the shape, weight and shelf-life of strawberries, contributing a staggering €1.05 billion to the European strawberry market per year, new research suggests. By blocking bees from a set of plants, the researchers demonstrated the substantial effects of bee pollination on the quality of the fruit.

A framework to value marine and coastal zone ecosystem services, which acknowledges but transcends monetary value, has been proposed by researchers. Using this approach, coastal managers can integrate the different values placed on ecosystem goods and services by various stakeholders to assess how these values affect planning decisions.

In the Mediterranean region the demand for natural resources and ecological services is two and half times greater than ecosystems’ capacity to provide them, recent research has found. To meet this demand, countries rely on imports, exposing themselves to price volatility and potential resource shortages. According to the authors, a 10% increase in global prices would particularly impact vulnerable countries such as Jordan, which would see its trade balance worsening by 2.4% of its gross domestic product.

A team of Italian scientists has published a study highlighting the important role of intersectoral linkages and eco-innovations in shaping industry’s environmental performance (a measure of its ability to meet environmental targets and objectives) across Europe. The research indicates that eco-innovation can produce positive effects, both directly (in the sector where it is developed) and indirectly (in linked sectors at home and abroad). These insights are relevant to corporate and policy governance strategies aimed at maximising the environmental and economic potential of novel green technologies.

New research has compared life cycle environmental impacts of new petrol and diesel cars and highlighted options for improvement. It indicates that the greatest improvements are achievable through more efficient power trains and lightweight cars. However, these technological solutions come at a financial cost whereas other improvement options, such as behavioural changes, provide a win-win solution.

Although national and European policy supports the importance of outdoor recreation, there are few binding commitments for action, according to new research. In particular, monitoring of recreation in forests is rarely mentioned in national policy and the study suggests comparable European data could inform firmer decision-making.

Woodlands in the grounds of old manor houses or castles can provide high quality habitat for numerous forest species, a recent study from Estonia concludes. The researchers found that, compared to nearby forests, old rural park woodlands appeared to be better at supporting biodiversity.

The impacts of drought on European trees are of high concern, especially under a changing climate. New research has indicated that, if summers become continually drier, sensitive species, such as larch and spruce, will suffer reduced growth in some Alpine areas. This could potentially compromise ecosystem services provided by forests in these areas.

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.

A study of two forest ecosystems in Spain has found that land-cover maps of watersheds, ecosystems hosting key interactions between vegetation, wildlife, and water, are made more accurate by the inclusion of LiDAR data — a type of remote sensing that pulses laser light at a target to measure vertical distances for use in 3D-mapping an environment. This has important implications for ecosystem monitoring, flood mitigation, and forest management, fields in which accurately characterising an environment is key.

Sustainable development aims to improve quality of life without compromising the well-being of future generations. A new study highlights the challenges of setting environmental sustainability goals and cites the EU Climate and Energy policy package, with its ‘20-20-20’ targets, as a model example.

‘Doing good’ can lead to ‘doing well’ for companies that implement corporate sustainability, according to a new study by Polish researchers. Eighty-five American companies that met corporate sustainability criteria proved to have better returns and greater stability in stock price than average, and better growth rates than their less sustainable counterparts.

As buildings become increasingly energy-efficient in terms of heating and operation, researchers are highlighting the importance of reducing the energy needed to construct the buildings. However, there is a lack of accurate, consistent data, or a standard methodology to properly assess energy requirements at this stage, a new study has found.

Including civil society organisations (CSOs) when negotiating climate policy can mobilise public support for international agreements, a new study suggests. Using online surveys researchers found that the popular legitimacy of global climate governance decreases when CSOs are excluded.

A new tool to help planners choose urban designs that positively influence flows of energy, carbon, water and pollutants in cities is presented in a recent study. It is designed to integrate scientific knowledge into the planning process and support cities in achieving sustainability objectives.

Plans for new Marine Protected Areas (MPAs) need to consider social impacts alongside economic and environmental impacts, according to a recent study, which found that an MPA in the UK has increased some tensions within its local community. The researchers suggest that collaborative management could also help increase support for MPAs and reduce stakeholder conflict.

A new five-step method has been developed for assessing the resource efficiency of products and improving the reuse, recycling and recovery of material at a product’s end of life. The Resource Efficiency Assessment of Products (REAPro) method allows the identification and testing of practical measures to improve resource efficiency at both the product and policy level.

Urban green spaces provide important ecosystem services in cities, from recreation to the mitigation of noise and air pollution. This study quantified the ecosystem services (ES) provided by green spaces in Rotterdam, the Netherlands, using new methods to evaluate high-resolution land-cover data. The findings show that different types of green space provide different ES, highlighting the importance of careful design during city planning. The authors say their method to map ES supply will aid the design of healthy, climate-resilient cities.

Regardless of how well-designed environmental legislation is, for it to be effective it must be properly enforced. This study explored the enforcement practices of several environmental agencies, recommending that strategies are chosen based on regulatory context and environmental risk.

Solar-powered irrigation that delivers water directly to plant roots could help ensure food security in Africa, say researchers. Their study in the Sudano-Sahel region of West Africa indicated that this irrigation method could increase both household income and nutritional intake, particularly during the dry season.

Individuals and groups of individuals have been influential in changing the Tisza River water policy in Hungary, according to a new study. A shift away from engineering solutions towards sustainable flood management was achieved through new policy ideas being recognised by civil servants at the national level and a regional coalition championing the ideas at the local level.

Collecting, or ‘harvesting’ rainwater may help society cope with a number of problems, such as water shortages, flooding and the degradation of urban streams. Urban roofs make up about half of the total sealed surface (‘unnatural’ surfaces, which cover over natural surfaces, such as soil) in cities and contribute the most to stormwater run-off, which could be harvested for other purposes. To maximise this potential, it is useful to know which type of roof can harvest the greatest amount of good quality water.

Rebates and exchange programmes for showerheads, toilets and washing machines can produce significant water savings, according to a US study. The study observed a 6 to14% reduction in household water demand for the first two years after these efficiency programmes were introduced by a water authority in Florida.

Improving the efficiency of irrigation can help farmers increase profits, meet regulatory requirements for renewing licences, and demonstrate sustainable use of resources for supermarket grower standards. A recent study has assessed water irrigation efficiency in the UK and suggests that the ‘pathway to efficiency’ approach can help farmers and water regulators manage irrigation and water abstraction.

Valuations of water quality as an ecosystem service often fail to include related services like recreation or human health, and do not consider the effects of water quality changes due to management. Researchers have now developed a template for valuation that considers multiple services and links management actions to changes in water quality and ultimate economic value.

Improving local water quality could mitigate the damaging effects of rising CO2 on marine ecosystems, new research suggests. Scientists in Australia found that nitrogen pollution in seawater, when acting in combination with heightened CO2 concentrations, had a significant effect on the growth of turfing algae, which displace kelp forest ecosystems.

Blue-green algae, or ‘aquatic cyanobacteria’, can produce harmful toxins and present a serious health hazard when they bloom in large numbers. Researchers from Germany have now identified plant species that could be used to sustainably treat water by removing such cyanobacterial toxins.

Modern flood risk management is placing more emphasis on improving the resilience of communities prone to flooding. By examining three case studies, a recent investigation has provided insight into how resilience is put into practice, suggesting that clearer identification between the roles of different actors and better communication to the public is needed for successful implementation.

Shellfish harvesting areas in the UK are cleaner, thanks to sewerage improvement schemes over the last decade which have lowered average levels of Escherichia coli in oysters, mussels and other commercially-important species and boosted the shellfish industry’s economic value. Addressing the additional pollution risks from agriculture could further reduce contamination and human health risks.

Investment in cycling initiatives, such as creating new cycle lanes or providing training, can increase the number of people who routinely cycle to work, a new large-scale study in the UK suggests. Town-wide cycling initiatives seemed to be particularly successful when they included workplace measures such as bike lockers, showers and cycle parking.

Changing agricultural management practices can significantly improve water quality, according to a long-term study. The researchers found that in a US lake the total amount of suspended sediment fell, and water clarity increased as a result of multiple integrated practices implemented to reduce runoff in the surrounding area. These included introducing buffer strips of vegetation and planting trees.

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.

Phosphorus in sewage and manure could be more available to crops than previously thought, suggests new research. The study found that some forms of sewage and manure treatment provided plants with more phosphorus than conventional inorganic fertilisers.

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.

Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the pollution of marine ecosystems.

Water policies at European and French national levels have led to a clear improvement in the water quality of the River Seine, a new study has found. A significant reduction in phosphate and ammonium pollution and increasing oxygen concentrations are evident. However, nitrate concentrations are still higher than the recommended level for good freshwater status, despite substantial reductions of surplus nitrogen in agricultural soils over the past few decades. The researchers recommend strengthening current agri-environmental management measures to help the river to return to a fully healthy status.

After the 2002 floods in Germany — the country’s most economically damaging natural hazard — efforts were made to develop a more integrated system of flood management. A recent study has reviewed how those measures helped Germany to cope with the more recent floods of 2013, highlighting developments in early-warning systems and consideration of hazards in urban planning. The researchers also discuss areas for improvement, including citizen engagement and cross-border collaboration.

Sustainable river management is increasingly informed by hydromorphological stream assessments — evaluations and classifications of stream conditions which account for both hydrological (the movement, distribution and quantity of water) and geomorphological (the processes and forms deriving from the interactions of water and sediment movement) features. In order to provide a more accurate and comprehensive assessment of river character and dynamics, scientists have developed three novel methods. Together, these tools represent a promising technique for conducting collaborative assessment and monitoring of river conditions in Europe.

A simple fix has helped the airline’s cabin crew save 20 minutes of their work, helping the airline improve turnaround times for better on-time performance.

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.

A new study has reinforced the view that biodiversity improvements and greater provision of ecosystem services are complementary. An analysis of projects that restored ecosystems indicated that restoration produced a 44 per cent increase in biodiversity and a 25 per cent increase in the provision of ecosystem services.

Actions to reduce emissions caused by deforestation and degradation (REDD) also enhance ecosystem services, according to a new report. Using a case study from the Amazon it indicated that REDD support schemes can also help maintain water levels and quality and protect soil from erosion.

New Europe-wide maps show the potential of landscapes to provide ecosystem goods and services over the next 20-30 years.

An analysis of conservation management strategies in the EU identifies a number of options for increasing the cost-effectiveness of conservation within the Natura 2000 network of protected areas. More time and money should be given to implementing conservation measures than planning them and governments should guarantee conservation funding over longer terms, say the researchers.
