Reluctance to use cost-benefit analysis (CBA) in environmental decision making in Germany stems from a preference for traditional approaches and a fear that it leads to loss of influence. This is suggested by new research based on interviews with those responsible for water policy management.

We need a better understanding of how the public perceive the risks of population growth, a new discussion paper argues. Research into public perceptions of the environmental and social challenges of population growth could guide behavioural-change communications to help limit growth and manage the difficulties. Specific communication issues include how to convey statistical information and the complex impacts of population growth.

More than 200 pieces of English and EU-wide marine environmental legislation have been analysed in a recent review. While complex, the legislation adequately covered all areas of the marine environment, the authors conclude. However, there is opportunity to remove overlap and conflicts between different legislation and improve cross-border co-operation.

The complexity of environmental issues and a lack of co-operation or shared objectives between parties involved in urban planning are preventing promotion of environmental sustainability, a new study suggests. The Finnish research, based on focus groups with 32 professionals in urban planning and environmental sustainability, suggests that the short-term economic goals of local authorities, the complexity of environmental sustainability, and a lack of co-operation between different decision-making groups in urban planning were creating barriers to achieving sustainability.

Marine protected areas (MPAs) are widely used to safeguard marine ecosystems across Europe. This study investigated the effect of a partially protected area (PPA) off the coast of Norway on a population of Atlantic cod (Gadus morhua). The PPA reduced the number of deaths due to fishing, increased survival and stimulated movement to surrounding areas. The authors say that preventing fishing altogether would increase survival even further and recommend no-take zones in areas where populations are severely reduced.

Approximately 1000 km2 of agricultural or natural land is lost every year in the EU due to land-use change. When this occurs close to residential areas, it can lead to conflict with local people. This study explored the views of local people in Romania, and compared them to experts. The authors discuss similarities and differences, and say that participation, where both locals and experts communicate, is key to developing effective land use policies.

Industry has traditionally claimed that strict environmental regulation has a negative effect on its competitiveness. However, a recent theory proposes it may actually increase productivity and innovation. This study used a large database of inter-sectoral transactions to investigate the effect of environmental taxation on manufacturing businesses across Europe. The findings show that environmental regulation can increase innovation and productivity.

The concepts of instrumental value (protecting nature for humans’ sake) and intrinsic value (protecting nature for nature’s sake) are fundamental to environmental policy. This paper — based on a literature review and critical analysis — argues that using these concepts alone overlooks important concerns for the environment. The authors recommend also considering relational values, which derive from the relationships between people and nature.

The top 10 environmental priorities for EU inland ports have been identified in a recent survey. A port’s relationship with the local community was the top environmental issue, followed by concerns over air and water quality. The survey provides the first benchmark of the environmental performance of inland ports, against which progress in their environmental management can be measured in the future.

Plastic pollution is a threat to marine ecosystems, as plastics are persistent, toxic and can accumulate up the food chain. This study assessed the abundance of small pieces of plastic in Alang, India. The authors found, on average, 81 mg of small plastic fragments per kg of sediment, which they say is the direct result of shipbreaking.

A large proportion of ships are recycled on the beaches of developing countries in Asia. This study considered shipbreaking in Bangladesh, using critical scenario analysis to explore different futures for the industry and its workers. The paper suggests that a radical shift in socioeconomic and political structures is needed to enable environmentally sound practices while retaining employment opportunities for local people.

When broken down, ships can release hazardous substances into the environment. This study investigated the environmental impact of shipbreaking in one of Europe’s few ship recycling yards, based in Portugal. The results reveal large differences between assessment methods and show that environmental impact depends on composition rather than size or class.

The Alang-Sosiya shipbreaking yards in India highlight the inequalities and opportunities of global waste management. The yards, which recycle retired ships from more economically developed countries, have dramatically altered the ecosystems and social structures of the local area. A study looking at stakeholder perceptions analyses different positions on the social and environmental impacts of the yards.

Landfill taxes and ‘enhanced waste management’ practices have been introduced to reduce the amount of waste that goes to landfill and to convert waste into useful products. This study investigated the interplay of these two policy options in Belgium, generating findings that could help Europe move towards a resource-efficient, circular economy.

Ireland’s Environmental Protection Agency (EPA) established the Network for Ireland’s Environmental Compliance and Enforcement (NIECE) over 10 years ago to ensure an effective, integrated, national approach to the enforcement of environmental legislation, as presented in a recent conference paper and a report from the EPA.

Enforcement of environmental law needs an integrated administrative and criminal sanction system, according to a UK lawyer and researcher. Writing in a recent paper, he argues that an integrated system allows the most appropriate response to each individual case of the law being broken

Milan and Seoul are considered by many as pioneering examples of cities in promoting a sharing economy. A new study has analysed governance in these two cities, and concludes that they have both laid the right foundations for a sharing economy to develop. The researchers propose that while such economies carry risks, they are also able to benefit the economy, environment, and society.

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.

To better understand the social and ecological implications of the non- food sector of the EU’s expanding bioeconomy, an economy which is based on the production and conversion of renewable biological resources into products and energy, a study has assessed the global cropland footprint of the region’s non-food products. The results show that the EU was the world’s biggest consumer and importer of these products from 1995 to 2010: two-thirds of the cropland required to satisfy the EU’s non-food consumption is located elsewhere in regions including China, the USA and Indonesia, bringing potential impacts for distant ecosystems. These findings can inform EU policymaking and support the EU Bioeconomy Strategy.

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.

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.

Climate change is expected to increase the intensity and occurrence of regional floods in Europe. A recent study has examined existing natural and constructed retention (or holding) basins that can be adapted to provide flood defences. As part of the study, a classification system for flood defence structures was developed to help Member States design sustainable flood risk management plans.

New research in the Netherlands indicates that spatial planning to manage flood risk, such as the elevation of residential areas and the exclusion of vulnerable land uses from flood-prone areas, is underused. Its use appears to depend on governmental requirements, previous experience of flooding and previous experience of using spatial planning as a mitigation strategy.

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.

Monitors in showers, which display how much water is being used and sound an alarm when a limit is reached, have significantly cut water consumption in household trials. The immediate feedback from the alarm monitor made consumers more aware of their behaviour, which they could then modify.

Carbon footprints are an established means of communicating one aspect of a product's environmental impact. New research suggests additional 'nitrogen footprints' for food products could give consumers a more informed choice and help reduce eutrophication in water. However, it warns that there are environmental trade-offs for some food groups, for example, oil products have a small nitrogen footprint, but a fairly large carbon footprint.

A new study has analysed water shortages around the world over the past two millennia. Population growth has been a significant pressure on supplies and will continue to increase in threat in future. Dealing with water scarcity will therefore increasingly require improved water governance, management and policy measures, which are fully integrated into societal development.

Only wetland environments with high sediment input from rivers can keep pace with rising sea levels, according to a new study. However, human activity is destroying wetlands’ natural defences, making their survival increasingly unlikely. The researchers call for sustainable management approaches to protect wetlands under future climate change projections.

Researchers attempting to establish the limits of coastal waters in Europe have found that national declarations of coastal waters contain a number of inconsistencies regarding the definition from the Water Framework Directive. In particular, the national declarations over-estimated the area of coastal waters by almost 12% overall, which could affect the results of ecological assessments required by several major EU environmental policies.

A new study has estimated the water consumption and land use for the production of 160 crops that constitute most of the world’s cropland. The results suggest that, collectively, wheat, rice, cotton, maize and sugar cane account for 49% of water scarcity and 42% of land resource stress caused by worldwide crop production.

New research reveals how scientists can monitor water quality in European lakes using sensors mounted on satellites. The technique is a promising and cost-effective new tool to classify and monitor the ecological status of lakes more reliably under the Water Framework Directive (WFD).

A new Spanish study has highlighted current developments in the tourism sector that have significant implications for water supply and demand, but are barely addressed in recent land use policies. The findings indicate that any tourist destination that is to follow the ‘quality tourist’ model will have an increased water demand in domestic residential areas, which is one of the biggest threats to sustainable water management.

Desalination plants, powered by wind energy, offer the potential to produce freshwater using a renewable source of energy. A recent study has explored some of the challenges of integrating wind energy with desalination units, and suggests combining wind with other forms of renewable energy, or constructing a system that operates with variable energy input would help overcome problems with wind powered desalination.

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.

Tiny plastic particles from laundry wastewater are being washed into the marine environment, according to recent research. The plastic, from synthetic clothes cleaned in domestic washing machines, is a significant source of contamination and, unless measures are taken to address the problem, growing coastal populations will only exacerbate the situation.

A recent study suggests that blocking ditches originally dug in peatlands to drain water is an effective restoration method, but is influenced by local conditions. Restoration efforts should therefore be monitored over long periods of time at the landscape level to fully evaluate their impacts.

A review of research into surface water runoff from agricultural land has found that less intensive management leads to more predictable runoff generation over the course of a year. The review also identified several gaps in our understanding, which need to be better represented in hydrological models if the environmental impact of runoff is to be reduced.

A recent study suggests that, since forests play a significant role in the regional and global supply of water vapour in the atmosphere, they should be thought of as global public goods and not viewed negatively in terms of water consumption.

Energy production uses large quantities of water and, in turn, water provision requires considerable amounts of energy. A new study has investigated the interconnection between water and energy, the ‘water-energy nexus’, in Spain and found that 5.8% of total electricity consumption is for water-use and 25% of water withdrawals are for energy generation.

A new method of determining water flow in complex river basins has been developed that balances ecosystem protection with the legal rights to use water by hydropower operators, farmers and municipalities. A recent study has applied this method to a new river basin management plan in Spain.

A recent study has assessed the costs and effectiveness of reducing phosphorus pollution for lakes in Scotland, UK, to achieve good ecological status as required by the EU’s Water Framework Directive (WFD). It was found that phosphorus in 72% of the lake area in Scotland could be mitigated at a cost of £5.7 million (€7 million) per year, which is considered a proportionate or reasonable cost given the resulting social benefits.

Whatever form it takes, urban growth leads to reduced groundwater availability, according to a new study. The paper highlights the fact that urbanisation is not always sustainable and recommends that planners consider no-growth scenarios for economic development.

One of the most common causes of water quality impairment is suspended particulate matter (SPM). A study by a team of UK researchers suggests that standards for SPM set by EU member states to help achieve the WFD should reflect the natural differences in the levels of this pollutant that are expected in contrasting environments. Their study provides hints as to how a potential alternative system for regulating SPM concentrations might be devised.

Under pressure from rising food prices, many nations have begun to acquire large tracts of agricultural land in foreign countries, a practice known as ‘land grabbing’. New research has now quantified current levels of land grabbing and demonstrated that it is accompanied by concerning levels of ‘water grabbing’ which could affect water supply in the ‘grabbed’ countries.

Spanish Basque Country, grasslands were found to supply the greatest amount of river water, followed by native woodlands, with exotic woodland plantations providing the least. Researchers also call for more comprehensive analyses of ecosystem services, including carbon sequestration and biodiversity, to inform land-use policy.

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.

Population growth of any country is ultimately dependent on that country’s access to freshwater resources, which also determines its capacity to produce food. A new study shows that population growth is expected to decline in countries with low water resources, as water-rich countries reduce food exports in order to feed their own growing populations.

Improved understanding of flash flooding could be achieved through post-flood observations, re-examination of weather radar data and the use of combined weather and hydrological modelling, according to the recent HYDRATE research project. This information can be used to improve flash flood forecasting.

Research from Slovakia suggests that the total area of change in land cover, as well as land management practices, are more important in generating floods than the type of land cover change, such as deforestation.

A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World Health Organization (WHO) warnings.
