Tiny organisms called phytoplankton, which are crucial components of marine ecosystems, have been slowly disappearing over the last century, according to researchers. The decline is worrying because it may have profound effects on marine life, fisheries and carbon cycling. The study suggests the decline in phytoplankton could be linked to climate change.

Phytoplankton are essential to marine food webs and fisheries. However, a new study indicates that their levels have declined in the North Atlantic since the beginning of the 19th century. This coincides with weakening ocean-circulation patterns, partly caused by melting ice caps. If the melting continues, the study warns of a dramatic fall in North Atlantic plankton levels that could have cascading effects across marine food webs, reducing the ocean’s ability to absorb carbon and threatening the supply of seafood for humans.

Rooftop gardens in cities could provide more than three quarters of the vegetables consumed in them, a case study from Bologna, Italy, suggests. If all suitable flat roof space was used for urban agriculture, rooftop gardens in the city could supply around 12 500 tons of vegetables a year whilst also providing a range of ecosystem services, the researchers say.

Urban agriculture is becoming increasingly popular. A recent assessment of rooftop farming in Barcelona shows differing attitudes towards the practice, and provides important recommendations for the development of agricultural policy for the 21st century, such as including food production as a potential use of rooftops in planning legislation.

New barriers have been developed to prevent invasive American signal crayfish from moving upstream and colonising important European crayfish habitat. The barriers, designed to stop crayfish but allow fish to pass, have been found to be effective where water flow rates are sufficiently high.

Desktop three-dimensional (3D) printers, available for use in offices and homes, can release between 20 and 200 billion ultra-fine particles (UFPs) per minute, finds new research. UFPs may pose a risk to health, and the study’s authors recommend caution when operating 3D printers inside unventilated or unfiltered indoor environments.

Identifying emerging research areas and technologies is important for decision makers, but notoriously difficult to do. This study presents a new way of searching the literature to identify emerging topics, which will help policymakers, industry and funding bodies to make better decisions.

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.

A recent study helps city planners find the greenest and most effective way of producing renewable energy, crops and water on rooftops. The researchers developed a method for analysing the performance and environmental impacts of different combinations of rooftop rainwater-harvesting-, energy- and food systems. It could aid efforts to promote urban self-sufficiency and a sustainable circular economy, they suggest.

Planting trees and maintaining a well-balanced mix of vegetation in urban 'green spaces' can enhance the species diversity of birds and compensate for the negative effect of building, according to new research. Scientists recommend that increasing tree cover rather than limiting new development is the most effective long-term strategy to improve bird diversity in cities.

One strategy to halt the loss of biodiversity has been to create protected areas in the sea and on land. However, a new study suggests that unless additional measures are taken, particularly those that tackle human population growth and the increased use of natural resources, even the development of new protected areas will be unable to reverse the trend of global biodiversity loss.

Large carnivores play important roles in ecosystems by regulating populations of herbivores and other species. Understanding how human activities affect the role of predators, particularly within human-modified systems such as agricultural landscapes, is therefore important. This study investigated how predator and prey populations were distributed in Transylvania, Romania, and assessed them in relation to human activities. The research highlights how relationships between large carnivores and people need to be considered as part of biodiversity conservation efforts, especially considering the successful recovery of several large carnivore populations within the EU.

A new study suggests that the energy sources used in chemical production contribute significantly to environmental damage in developed countries. The researchers recommend increasing the efficient use of heat and electricity, in addition to reducing direct emissions of harmful pollutants, to dramatically improve the environmental impact of the chemical industry.

Titanium dioxide nanoparticles are entering the environment in ever greater quantities as a result of their widespread use in consumer products and as a disinfectant of sewage. Researchers have recently discovered that titanium dioxide nanoparticles have a toxic effect on marine phytoplankton when exposed to normal levels of ultraviolet light found in natural sunlight.

Copper (Cu) is frequently used in agricultural practices, particularly in fungicides, used extensively in the management of permanent crops, such as vineyards, olive groves, and fruit orchards — all crops of significant economic importance to the EU. An investigation into the factors influencing Cu distribution in the topsoils of 25 EU Member States has identified that, in conjunction with other factors such as topsoil properties, land cover, and climate, such agricultural management practices play a role in influencing Cu concentration. The analysis used 21 682 soil samples from the EU-funded Land Use and Coverage Area frame Survey (LUCAS)¹ and found that vineyards, olive groves, and orchards had the highest mean soil Cu concentrations of all land use categories. The findings highlight the major impact of land use and agricultural practices on soil Cu concentrations and emphasise a need for more sustainable land management practices.

Rare earth elements (REE) are used to make many low-carbon technologies, including electric vehicles and wind turbines. Mining and processing of REE, which mostly takes place in China, has a reputation for causing environmental damage. A new study presents a method for evaluating the environmental impacts of REE production based on life-cycle assessment (LCA: a way of determining a product's overall impact during some or all of its journey from extraction to end-of-life). The researchers applied the method to a prospective REE mine in Malawi, south-east Africa, to reveal the most environmentally impactful stages of production, and the greenest source of energy.

According to new research, emissions of anthropogenic nitrous oxide (N2O) are now causing more damage to the ozone layer than those of any controlled ozone depleting substance and this is projected to remain the case for the rest of this century. The study suggests that limiting N2O emissions could help both the recovery of the ozone layer and tackle climate change.
