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.

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.

Global interest in urban agriculture is growing. However, the importance of local context is not reflected in current governance approaches, argues a new study which evaluated urban agriculture in Belgium and Poland. The authors say that considering city-specific factors can help urban agriculture achieve its full potential, and recommend a broader policymaking strategy that considers the benefits beyond food production.

Systems for ensuring industry compliance with pollution regulations in eight countries have been assessed by an OECD study. OECD countries have been making good progress in designing and introducing new environmental policies. However, they are generally not on track to meet the policies’ goals. A major reason for this ‘implementation gap’ is low compliance with respective regulatory requirements, for instance, emission limit values.

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.

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

Policymakers often have to make decisions under great complexity, uncertainty and time pressure. A new study presents a support tool for the first stage of policymaking: identifying and exploring alternatives to solve problems. The software tool, called QUICKScan, increases the speed of this process and combines the input of many stakeholders in participatory workshops. It has been applied 70 times in 20 different countries, for a wide range of environmental policy issues.

The effects of market regulation and environmental policy on eight types of renewable energy in the EU are identified in a study which examines nearly three decades’ worth of data. The researchers found that reducing entry barriers is a major driver of renewable energy innovation and that the ability of environmental policy to promote renewable energy innovation depends on the technology; for example, quota systems appear to work better with older technologies.

Researchers have developed a new indicator for policymakers, which shows the strength of renewable-energy technologies for electricity production in a country’s energy security. They compare their Renewable Energy Security Index (RESI) to the carbon footprint, in that it is easy to report and practical to use in energy policy.

International trade has increasingly relied on material resources since the 1990s, according to a new study. The research used the most detailed global computer model available for capturing the effects of international trade on the environment and on the efficiency of resource use between 1995–2011. Sharp increases in the trade of cheap ‘fast fashion’ and mass market electronics are highlighted as two of the fastest growing drivers of this change in material inefficiency.

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.

Extended producer responsibility (EPR) and other regulatory influences are essential to battery recycling in Finland, a new study finds. The researchers compare this with the situation in Chile, where a lack of appropriate legislation prevents recycling companies from overcoming the technical and financial challenges of battery recycling. The study helps policymakers understand how political, social, and cultural factors can support companies in their move towards circular-economy business models.

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.

The German Renewable Energy Sources Act was introduced in 2001 to encourage an increase in renewable energy supply. Since then, supply has increased from 7% (in 2001) to 37% (in 2017. Wind energy is an important part of Germany’s renewable energy production — but deploying sufficient turbines to achieve the climate goals requires a large amount of raw materials, many of which are metals in limited supply. This study found copper and dysprosium to be the most critical of these metals, as they could face future bottlenecks and are essential elements in present and future turbine design.

The announcement of a new no-take fishing zone in the Pacific led to a 130% increase in fishing activity ahead of its implementation, satellite data reveal. Although fishing activity dropped to zero once the marine protected area (MPA) came into effect just over a year later, the study warns that the pre-emptive short-term surge in fishing could have caused long-term ecological damage.

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 study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites.

Increasing crop production to meet demand for biofuels potentially increases the use of nitrogen fertilisers, which can lead to nitrate pollution in surface and groundwater. A new study is the first to consider the unintended extra energy needed to treat water to remove nitrate contamination in drinking water supplies.

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.

A new study has indicated that, although greywater treatment and re-use could produce water savings of up to 37 per cent, it could not comprehensively remove hazardous substances. Complementary measures are needed, such as eco-labelling and regulatory controls.

'Greywater' that is recycled from household washing can be used to irrigate home gardens, according to a new study by Jordanian researchers. The researchers found that treatment units supplied by the Jordanian government produced small quantities of recycled water that could be used to irrigate gardens, whilst meeting national standards for irrigation of trees and many home-grown crops.

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.

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.

A recent study highlights the need to consider water consumption when evaluating low-carbon energy production systems, such as biofuels and solar photovoltaic systems, for use in transportation.

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.

Ten years ago the European Water Framework Directive (WFD) introduced a shift in water management, placing ecology at the centre of decision-making. A new review of its implementation identifies both the achievements of the WFD and its ongoing challenges, providing recommendations on how to overcome these.

A new study has analysed public perceptions of greywater re-use systems in Barcelona, which are being increasingly employed to save water during times of shortage. Several factors, including perceived health risks, system reliability and maintenance costs, appear to influence public acceptance of the technologies.

Increases in population and urbanisation are challenging current systems of water supply. A new study has assessed existing examples of alternative supply systems, such as wastewater reclamation, rainfall collection and desalination of seawater. It suggests that adopting several types of system may provide a better and more flexible solution.

A new study identifies ways to reduce the risks to water quality associated with underground CO2 storage. The study, based on laboratory tests, shows that CO2 leakage could pose a risk to overlying fresh groundwater. Careful storage site selection, coupled with regular site monitoring, is a pre-condition to reducing risks associated with CO2 leakage.

Populations of organisms that live on the bottom of an aquatic ecosystem, the benthic community, can be assessed to determine the health of the ecosystem. New research explores the many existing methods for assessing benthic communities to ensure that the most appropriate and useful tests are used under the Water Framework Directive (WFD).

To assess the impact on ecosystems of chemical contamination in aquatic environments, scientists need to measure not only the concentration of the contaminants, but also the extent to which they can disrupt biological processes at a cellular level in plants and animals and at an ecosystem level. According to a new study, considering these complex inter-relationships in combination will help improve the ecological status of waterways, in line with Water Framework Directive (WFD) commitments.

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.

Phosphate is added to domestic drinking water to reduce lead levels in the UK, to help meet EU Drinking Water Directive standards. New research has now found that phosphate can also reduce the amount of copper in domestic sewage by more than a third. This method could help Member States meet forthcoming “safe” levels for water discharged to the environment, under forthcoming EU Water Framework Directive (WFD) proposals.

The importance of addressing eutrophication to improve the ecological health of coastal and marine waters has been identified in the EU Marine Strategy Framework Directive1. A new study discusses possible methods for assessing and monitoring eutrophication, including which indicators to monitor.

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.

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 substantial amount of energy is needed to manage all the water used in the mass cultivation of microalgae for biodiesel. A recent study suggests that seven times more energy is required to manage the water, than is delivered by the biodiesel when it is used as fuel.

The largest investigation to date into the extent of human-induced pressure on European rivers concludes that around 80% of rivers are affected by water pollution, water removal for hydropower and irrigation, structural alterations and the impact of dams, with 12% suffering from impacts of all four.

A new study has investigated the restoration of a damaged estuary in Spain by comparing the costs of installing sewage systems with the associated benefits for water quality and biodiversity in the area. Long-term benefits, particularly in the inner part of the estuary, increased with investment in sewage treatment schemes.

Individuals’ willingness to pay (WTP) for environmental improvements is influenced by political affiliation. However, the picture is more complex than previous studies suggest according to new research, which concludes that how an environmental programme is delivered, i.e. by private companies or by the government, is more important for right-wing voters than for left-leaning voters.

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.

Soil conditions play a crucial role in determining water runoff and retention in forested sites, according to new research. Soil characteristics, such as compaction, play a greater role than forest type in determining water dynamics.

Scientists have modelled the potential benefits of decentralised flood protection (DFP) in Central Europe and conclude that it could be a significant step towards natural flood management in the EU.

Dishwashing is responsible for over half of tap water used in the kitchen, according to the results of a new study, which also suggest that people who live alone consume double the water per person that those that live in a four or five-person household. Although relatively few households were studied, this research could prove useful in helping develop consumer advice for saving water.

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.
