The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ecological considerations of micro-turbines.

Agricultural intensification can significantly affect soil ecosystems and the services they provide, new research suggests. Examining soils across Europe, the study demonstrates that high intensity arable land uses have lower diversity and biomass of soil organisms than lower intensity arable or permanent grassland, affecting the carbon and nitrogen cycles in the environment.

Despite the substantial impacts warming and drought can have on soil bacteria and fungi, these are not sustained if external conditions re-stabilise, a new study suggests. Small-scale experiements in five countries across Europe to show that even if warming and droughts continued for over a decade, there were no lasting effects on key properties of soils, such as growth rates, when the soils were allowed to re-stabilise in a laboratory over seven days.

The world’s ocean ecosystems will suffer warming, increased acidity, low oxygen and reduced primary food supply as a result of rising CO2 and this is likely to have dramatic environmental and social impacts, a new study concludes. It predicts that the most vulnerable low-income countries, where 870 million people are dependent on marine ecosystems, would be affected if CO2 emissions are not tackled.

The greenhouse gas (GHG) emissions produced during the decommissioning phase of nuclear power plants may have been underestimated in previous assessments, new research suggests. The study estimated that the decommissioning process for a German plant resulted in 1 651 265 tonnes of CO₂ (or equivalent) emissions, or 0.825 tonnes of CO2 equivalent per tonne of waste. While the researchers acknowledge that impact is highly dependent on the unique characteristics of each decommissioning project, these results raise questions as to whether this phase has been accurately assessed in earlier research.

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

Most emissions of nitrous oxide (N2O) are linked to the use of nitrogen (N) fertiliser in agriculture, highlighting a need for agricultural management practices that reduce emissions while maintaining agronomic productivity. A new study has assessed the long-term impact of conventional tillage (CT — where soil is prepared for agriculture via mechanical agitation) and no-tillage (NT) systems on soil N2O emissions and crop productivity in rain-fed Mediterranean conditions. The findings show that, over a period of 18 years, mean yield-scaled (i.e. per unit grain yield) soil N2O emissions (YSNE) were 2.8 to 3.3 times lower under NT than CT. The researchers therefore recommend NT as a suitable strategy by which to balance agricultural productivity with lower soil N2O emissions in rain-fed Mediterranean agroecosystems.

The most effective way to lower the greenhouse gas (GHG) emissions associated with metal production is to pursue a circular economy for the material in the long term, says a recent study. This century will see a high demand for seven major metals; the resultant overall environmental impact is expected to outweigh any environmental savings that may result from greener production processes or an increased use of renewable energy.

Precious metals, such as gold and silver, constitute a small but valuable part of waste electrical and electronic equipment (WEEE). New research suggests that significant amounts of these precious metals are lost in the initial stage of the waste recovery process and makes recommendations for improvements in the recycling chain.

Recycling green waste as compost could match the environmental benefits of converting it into renewable energy, in terms of CO₂ savings, according to new German research. It suggests that the two forms of waste management should be seen as complementary and both should receive subsidies.

Researchers have developed a new tool to evaluate the economic viability of biogas production from agricultural waste, such as manure and straw. It focused on a co-digestion method where farmers treat several types of waste together, including industrial by-products, such as glycerol.

Although life cycle assessment (LCA) is a widely accepted method for supporting decision-making, it can face difficulties when being translated into practical life cycle management. A recent case study on local waste management has led to the development of several principles to ensure that LCAs are understandable and applicable.

Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics.

Eco-innovations which help prevent the production of waste are explored in a recent German study. It considers the drivers and barriers to the uptake of material efficiency measures in businesses, green procurement and product leasing schemes.

Flat screen televisions and computer monitors should be designed so they can be quickly dismantled for recycling, a recent study says. The researchers calculated that in order to ensure the recycling process remains economically viable, it must be possible to disassemble small screens in less than 11 minutes. Good design could lower the costs of recycling and enable near-total recovery of precious metals from the waste screens.

Mining metals from landfill sites can be economically viable, a recent project in the US has demonstrated. Approximately 34 352 tonnes of metals, conservatively valued at US$7.42 million (€6.67 million) were recovered from the 8 hectare ashfill site, according to researchers who analysed the project.

Sustainable urban waste management has progressed over recent decades, with recycling of waste becoming a routine activity across the EU. However, the increasing volume and complexity of waste poses ongoing challenges for policymakers and municipal administrators. New research suggests that a rethink around how household waste is sorted could lead to more resources being recovered from solid waste.

Around 50% of gold in used mobile phones is not recovered for future use, a new study finds. The researchers suggest that a global circular economy in mobile phones could be created by improving recycling of precious metals in phones in developing countries, as well as increasing the lifespan of phones and improving collection after use. These changes will reduce pressures on non-renewable resources and close ‘metal flow loops’.

Recycling has significant environmental benefits and is key to a circular economy. The EU has set a goal for Member States to recycle 50% of their municipal waste by 2020 and plans to set a 65% target for 2030, although progress towards this goal is variable. This study assessed a waste separation scheme in Malta, a Member State with traditionally low levels of recycling. Even though mixed waste was collected more frequently and for free, residents contributed to the voluntary recycling scheme, with participation increasing over time. This study provides useful insights for developing voluntary policy approaches.

A successful circular economy for valuable metals needs more than just effective recycling technologies, as a new study shows. The research, which explored the governance of recovering vanadium from steel-industry waste, revealed that industry stakeholders feel the prospect of financial gain, or reduced costs, through recovery is too distant at present. This perception could hinder a circular economy for critical materials from industrial residue, the study warns.

The potential of recycling aluminium scrap in Austria has been modelled in a new study. A surplus of mixed aluminium scrap is expected by 2045 if no advanced sorting technologies are applied. Increased demand for wrought aluminium alloys could mean this surplus occurs sooner. New methods to intensively sort aluminium could prevent this excess and contribute towards REACH1 recycling and climate targets.

Concern is growing around the issue of energy efficiency in data centres (DC) as more and more data are saved, processed, and transferred to facilitate myriad digital services worldwide. Utilising waste heat from DCs as heating for nearby districts may be a potential solution if technical and knowledge barriers are overcome, suggests this Finnish study, which identified key obstacles to this concept and possible methods of implementation.

How best to integrate the ecosystem services concept into regional planning? A recent study provides a practical example for an area in Germany that is faced with an increased risk of soil erosion under climate change. Researchers used a decision-support system incorporating ecosystem services to show that measures to reduce soil losses could also support a number of other services.

The decline of urban populations and abandonment of buildings and land could provide an opportunity to promote ecosystem services, a new study suggests. The researchers examined the relationships between the use of abandoned land and ecosystem services, providing insight into the pros and cons of different urban planning policies.

Simple characteristics of plant species - such as height or leaf size - can be used to predict the ecosystem services provided by the green roofs they grow on, a new study suggests. The researchers suggest that their method could be used to screen the thousands of potential plant species in order to optimize green roof design.

The EU-27 have committed to a strategic goal of developing an innovative economy based on biotechnology and renewable resources — a so-called ‘bioeconomy’. To achieve this, however, the EU must successfully mobilise resources such as residual biomass — or waste products from organic matter resources. A new study1 has quantified the potential of key residual biomass streams in the EU-27. The results show that residual biomass has a theoretical energy potential equivalent to the annual energy consumption of Italy and Belgium combined, with straw and forestry residues comprising the two most productive potential sources. The findings also reveal specific opportunities for regions including Paris (France) and Jaen (south-central Spain).

Researchers have devised a blueprint to integrate the efficient use of waste wood throughout a bioeconomy system — part of the economy that uses renewable biological resources from land and sea. This study assessed the environmental sustainability of three scenarios for increasing targeted levels of industrial symbiosis within the wood-based bioeconomy of central Germany, and found that, in most cases, the three alternative future bioeconomy networks outperformed the selected fossil-based reference systems, mitigating environmental impacts by 25 to 130%.

A new approach giving practical guidance for engaging communities in assessing and managing risks associated with re-development of contaminated land could help to smooth local decision making processes. It recommends a set of principles that risk managers and policymakers can use to shape their community engagement activities.

Compared with traditional remediation techniques used to remediate brownfield sites, supporters of phytoremediation argue that it is cheaper and more environmentally-friendly. A new analysis has reviewed its strengths, weaknesses, opportunities and threats, and suggests it is well suited to cleaning up sites with low to medium levels of contamination.

Use of environmentally-friendly LED lighting in Europe could play an important role in reducing energy consumption. A new report has now assessed the market for a mass adoption of such light sources, highlighting the need to ensure that the European lighting industry remains competitive.

By using design tools to increase sustainability at every stage of production, researchers have developed a new eco-light. The light, which uses low wattage LEDs and recycled plastic, has a substantially lower environmental impact than the traditional equivalent LED lights.

A three-step chemical process could successfully recover high-purity silicon from recycled photovoltaic (PV) solar panels, new tests show. The scientists behind the research say that recycling not only helps the PV industry meet regulatory requirements, but also reduces pressure on demand for raw materials.

Improving the energy efficiency of homes could have positive economy-wide impacts, recent UK research suggests. It would allow householders to spend the money they save on energy on other products and services. Although this additional demand and the associated production in non-energy sectors would partly offset the energy saved in the home, this ‘rebound effect’ does not completely outweigh the household energy savings.

Priorities for future environmental technology research and development were outlined by a study that surveyed experts in the field in 2010-11. The global environmental problems and potential solutions that new technologies could provide were identified and discussed in questionnaires and workshops. One of the main recommendations of the study was for a greater focus on flexible and cost-effective innovations that could alleviate potential environmental issues in countries with developing and emerging economies.

A new study explores how to weigh up the costs and benefits of technologies that extract phosphorus from livestock waste for re-use as fertiliser. Findings from a US case study suggest that recycling phosphorus in this way can cut both water pollution levels and the costs of cleaning up the mineral. However, the technologies’ long-term economic feasibility depends on the yield, quality, and market value of the recovered phosphorus.

Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

Ecosystems in the Catalan coastal system in Spain are worth €2,573 million per year to local citizens, according to new research. By placing a value on ecosystems the research has provided insight into integrated coastal zone management (ICZM) in the area.

A recent report has assessed the latest research on the adverse affects of noise on health, focusing on approaches to estimating the economic cost of noise. This information could help policy makers tasked with designing cost-effective noise reduction and management policies.

Payments for ecosystem services (PES) are one of a number of policy options available to support the provision of ecosystem services. Based on the characteristics of ecosystem services, a recent study has developed a framework for deciding when payments are a suitable tool for delivering ecosystem services.

Some 'intangible' ecosystem services, such as the aesthetic and cultural value, as well as the recreational use of land, are particularly difficult to price. New research has proposed three explorative methods to value these more intangible services using landscape evaluation, statistics on level of recreational use and the price of real estate in the area.

When natural disasters, such as earthquakes, storms and hurricanes, are reported in the media, they are often accompanied by an assessment of the cost of the disaster. While such information can be useful to help governments and international organisations target aid and recovery efforts, the details of what is included in the assessment, and the methods used, are often unclear.

Marine litter not only causes environmental damage, but has significant economic costs for industry. A recent study has now estimated that marine litter in the Asia-Pacific region is likely to cost over US$1.26billion per year in damage to marine industries. Policy options for reducing this cost are explored.

A new tool allows European businesses to see how, through informed decision-making, conserving the ecosystems they depend on is not only environmentally responsible, but can also increase profits, reduce risk and boost the value of their product or services.

A new study has proposed a method to place monetary value on green infrastructure at both a project and regional scale, which illustrates the value of investing in green infrastructure to the public and other stakeholders.

A new study has developed a system to assess the potential of ecosystems to supply ecosystem services in the EU-25 plus Switzerland and Norway. It is one of the first to use historical and projected data on land use change at a continental scale to estimate the provision of ecosystem services and to assess possible trade-offs between them.

There is increasing policy demand for the ‘scaling-up’ of ecosystem service valuations to a national or regional level, but available methods for doing this are limited. A new study has proposed a new scaling-up methodology and tested it by assessing the impact of climate change on European wetlands.

In economic terms, overfishing can be regarded as borrowing natural capital at a high rate of interest, according to a new study. Combining economic and biological principles, the study develops a concept that expresses overfishing in terms of the ‘interest’ that the fishing industry have to repay in future years as a result of lost income from depleted fish stocks.

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.

Researchers have developed a new approach for identifying regions that are most suitable for expanding ecosystem services. This could be used to help inform spatial planning decisions. By modelling ecosystem services’ opportunity costs in relation to agricultural revenue, the study provides a map of suitable areas of ecosystem service expansion in Eastern Europe.

Ecosystem services, such as coastal protection or water supply, form an integral part of ecosystem-based adaptation to climate change. However, preserving and restoring ecosystems and their services relies on the economic system that supports these efforts. Ecosystem services will not be best protected by the classic market framework, new research suggests.
