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.

Forest root systems increase soil strength and stability, thus protecting mountainous regions against gravitational natural hazards, such as landslides. However, tree roots are affected by factors such as soil properties, climate and disturbances, such as timber-harvesting or wildfire — and, as a result, a forest’s stabilising effect can vary greatly. This study of fire-disturbed beech forests explores how this effect changes over time. The results reveal that forests which have suffered moderate and severe wildfires completely lose their protective function within 15 years, placing those regions at high risk of landslide for up to 50 years after the fires.

New research in Australia has investigated the impact of labelling groceries with their level of CO2 emissions. A convenience store that introduced these labels found that the share of green (low CO2 emissions) purchases increased by 5 per cent. If these products were also low priced, the share of green purchases from the store increased by 20 per cent.

A standardised method to help choose the most cost-effective measures to remediate contaminated sites has been developed by Austrian researchers. The method takes into account a wide range of factors, including the principles of sustainability.

Congestion schemes can encourage people to adopt environmentally friendly behaviours more generally, a new study suggests. Researchers who surveyed car owners after the introduction of a congestion scheme in Stockholm found that after its introduction nearly half of people surveyed adopted greener behaviours such as conserving energy and water.

Norway has the highest battery-electric vehicle market share of any country worldwide. A new study investigated the incentives that have persuaded consumers to purchase electric vehicles in Norway, revealing that up-front price reductions (such as exemptions from purchase tax) are the most powerful incentives.

Administrative sanctions against environmental crime, such as fines, are generally easier and cheaper to implement than criminal punishment methods, such as prison sentences. This study explored enforcement methods for environmental crime in four Western European areas: Flanders (Belgium), Germany, the Netherlands and the UK. Based on their findings, the authors say it is most cost-effective — and may increase deterrence — to use both forms of enforcement.

For successful implementation of the Water Framework Directive, local planners will need specific targets, guidance on interpretation, and adequate resources to monitor progress, according to a recent study from Sweden.

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.

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.

New research has shown that policy measures in Denmark have successfully reduced total nitrogen loading to 10 estuaries by 39% in recent decades. However, to fully meet the targets of the EU Nitrates Directive and comply with the EU Water Framework Directive in a cost-effective manner, further mitigation measures must be tailored and focused to particular areas.

The impact of shale gas development on surface water quality has been explored in a recent study. Focusing on the Pennsylvania portion of the Marcellus Shale formation (which stretches from West Virginia to the Canadian border), the researchers conclude that shale gas wells and the treatment of shale gas extraction waste have measurable impacts on downstream surface water quality.

Water resource management needs to adapt to changes in climate, water demand and land use. A new tool has been developed by the LIFE+ Water Change Project to assess these ‘global change’ impacts on water resources and inform decisions on optimal adaptation strategies. A recent study has applied the tool to a river basin in Spain.

The socio-economic costs and benefits of adaptation to river flooding caused by climate change have been assessed in a new study. According to the study, adaptation measures could save €53.1 billion every year in flood-related losses across Europe by 2080.

Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems.

Climate change adaptation measures could improve the security of some groups of society at the expense of others, a new study concludes. Climate change adaptation policies should be based on genuine democracy and investment must be fairly distributed, to ensure that all at-risk groups benefit equally, its authors recommend.

Untreated wastewater from the baker’s yeast industry can be used to irrigate crops without negatively affecting the chemical quality of the groundwater beneath, recently published research concludes. Although the wastewater increased concentrations of some groundwater contaminants in an area with a high water table, these levels would not pose a risk to human health even if this water was used for drinking.

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.

Landfill leachate is the liquid that seeps through or out of waste deposits in landfill sites. EU regulations, such as the Landfill Directive1, have significantly reduced the volume of leachate produced, a study on leachate management in Ireland has found. Leachate, mainly from younger landfills in Ireland is, however, stronger since implementation of the legislation, and the researchers say the future treatment of leachate under stricter environmental protection regulations will continue to be a long-term concern for landfill operators and regulators.

A new framework has been developed to assess how effective Flood Emergency Management Systems (FEMS) are in Europe. Examining FEMS in five European countries, this study highlights the strengths and weaknesses of existing systems and makes recommendations for improving their effectiveness, particularly in relation to institutional learning, community preparedness and recovery.

Tradable permits have been proposed as a flexible instrument to integrate biodiversity conservation and economic development. New research indicates that permits are not a universal solution, but do have potential in certain economic and ecological situations.

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.

Transport infrastructure and urban sprawl are increasingly dividing up landscapes in Europe, threatening wildlife. A new report has quantified landscape fragmentation across 28 European countries. To prevent further negative environmental impacts, it recommends protecting unfragmented areas, monitoring fragmentation and applying fragmentation analysis in planning.

Hunting is not an effective tool for reducing damage caused by deer to managed forests in Europe, according to a recent assessment. Forests will be better protected through 'close-to-nature' management techniques, says the study, which evaluated the effects of different control mechanisms on deer populations and behaviour, including the influence of wild predators, such as wolves, and forest structures.

A recent project has developed a method to spatially target payments to areas where multiple ecosystem services, combining biodiversity conservation with carbon and water services, are jointly provided, so as to enhance the cost-effectiveness of the PES scheme. The study focuses on Madagascar, but the method could be applied at the national or regional level in any country.

The Chernobyl nuclear disaster is still having an impact on local biodiversity more than 25 years after the event, according to a new study. Researchers in France and the US suggest that rare bird species have been particularly affected by the accident and that genetic changes in plants and animals caused by radiation are being passed down the generations.

To encourage protection of the environment, payments for environmental services (PES) schemes offer direct incentives to individuals and communities to maintain or improve the provision of environmental services. A recent study suggests indicators to monitor PES must be chosen very carefully to help ensure that monitoring does not cost more than the payments themselves.

A case study in Sweden has shown that critically endangered European eels are being lost when they are sucked into the local nuclear power station???s cooling system. A process to pump the eels back into the sea could be beneficial to this species, the researchers conclude.

Seagrass restoration projects could effectively mitigate climate change, capturing up to 1337 tons of CO₂ per hectare after 50 years, new research suggests. If a carbon tax system was in place, the researchers add, these schemes would likely provide returns at least equal to the initial investment needed, assuming the tax was set at an appropriate level.

Ocean warming driven by climate change will reduce the amount of food reaching marine life on the seafloor, a recent study suggests. This would result in a 5.2% global reduction in seafloor biomass by the end of the 21^st century and biodiversity hotspots, such as cold-water coral reefs, will be particularly badly affected, say the researchers.

The importance of 'stepping stone' patches of habitat for biodiversity has been underestimated, a new study suggests. The researchers developed a new connectivity model, which better captures the effects of stepping stones on species movement.

Roads reduce the species diversity and distribution of frogs and toads, a new US study reports. The large-scale study used data from a national citizen science programme in which members of the public help monitor amphibian populations.

The IUCN’s Red List Index (RLI) of threatened species can be used to measure the effectiveness of conservation organisations. This is according to a new study which used the index to assess an organisation’s conservation impact on 17 species. Eight of these species saw improvements in their threat status, whereas 16 would have seen no improvement at all, or even deterioration, if there was no conservation action.

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.

Long-term biological monitoring is key to effective, evidence-based conservation management, new research concludes. However, greater collaboration is needed to ensure that scientists understand what kind of information is needed by conservation managers. In this way the data can deliver answers for the most important management questions.

Special conservation measures for bird species are required in EU Member States under Annex I of the Birds Directive. This study measured the efficacy of the Directive by comparing the population trends of these species to those of non-Annex I species. Annex I species had more positive trends in population from 1980–2012, despite extensive climate changes.

Biodiversity’s contribution to ecosystem services in grasslands — at different levels of the food chain (known as trophic levels1) — has been assessed in a new study. Higher species diversity across trophic levels — particularly for plants, insects and soil microbial decomposers — is important for the provision of multiple ecosystem services related to food production, recreational benefits, or climate regulation. Species diversity across different trophic groups was also found to be just as important in controlling ecosystem functioning as the management intensity of grasslands and environmental factors, such as climate or soil type.

Results-based agri-environment measures are an alternative to management-based measures that, in certain circumstances, could be both more effective and more cost-efficient, since their payment depends on the provision of the desired conservation outcome. This study reviews the success of a scheme, introduced in Germany in 2000, to preserve biodiversity in species-rich grassland.

The cost-effectiveness of agri-environment schemes to conserve species and habitats under the Scottish Rural Development Programme (SRDP) has been assessed by a recent study. Cost-effectiveness was found to vary widely between schemes. Improvements in cost-effectiveness relative to specific conservation objectives might be achieved with increased geographical targeting, advice and monitoring of impacts.

Surface water is considered to be of good ecological quality if the Maximum Permissible Concentrations (MPCs) of contaminants in the water are not exceeded. However, new research suggests that even when each individual contaminant does not exceed its MPC, water quality may be compromised by the combined effects of contaminants.

A new tool that predicts the effects of complex mixtures in water has shown promising results. It correctly predicted the impacts of toxic mixtures on the model species Daphnia magna, or water fleas, in over 90 per cent of cases.

New research compared criteria for accepting environmental risk as tools to evaluate cost-effective measures that would prevent tanker oil spills. The results suggest that the Cost of Averting one Tonne of Spilled oil (CATS) criterion is the best candidate, as it appears to be both practical and meaningful in actual risk assessments, and can lead to sensible recommendations.

Studies investigating the effects of pregnant women’s low level exposure to polychlorinated biphenyls (PCBs) on the weight of their newborn babies have produced conflicting results. However, new research, which involved 8000 pregnant women across Europe, adds to the mounting body of evidence that PCB exposure does in fact reduce birth weight.

A new study has examined contamination of fully grown soybean plants by two nanomaterials – nano-cerium oxide and nano-zinc oxide. The results could be concerning, as they indicate that the nanomaterials are absorbed by plants, possibly affecting growth, yield, and the fixation of nitrogen in soil, an important ecosytem service.

Populations of otters, grey seals and sea eagles are slowly recovering in Sweden, which is likely to be thanks in part to a ban on organochlorine chemicals, such as PCBs and DDT, in the 1970s, according to a new study. However, the research shows that negative effects of these chemicals on the reproductive health of female animals persisted for more than 15 years after the ban was introduced.

To date, it has been difficult to collect data that are robust enough to demonstrate specific effects of chemical pollution in rivers on aquatic wildlife. However, a recent study combining detailed chemical, toxicological and ecological data in three European river basins now provides evidence linking cause and effect by revealing significant differences in the effects of differently polluted sediments on the organisms living in the river basins and the riverbed biodiversity.

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.

Natural wetlands can provide effective long-term remediation of contamination from abandoned mines, new research suggests. The study examined a natural wetland receiving water from a copper mine in the UK, and showed that the water’s acidity and levels of toxic metals were significantly reduced once it had passed through the wetland.

A guide has been published on the known and potential health and safety effects of human exposure to graphene. It is designed to help inform those working with graphene and graphene-based nanomaterials and could be especially useful as a growing number of industries begin to experiment with and use these materials.

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.
