Land cleared in the tropics loses nearly twice as much carbon and produces less than half the annual crop yield as land in temperate zones, according to researchers. Their analysis of the trade-off between crop production and the loss of carbon stored in vegetation highlights the need to target reforestation in the tropics.

The greenhouse gas emissions from the construction of new houses are so high that they exceed the emissions from three decades of use, a Finnish study has found. The research is based on houses complying with recently introduced, energy efficient building regulations. According to the authors, as buildings become more efficient this ‘carbon spike’ associated with construction is more important than has been suggested by previous studies.

A recent study has projected changes in the spread of malaria caused by climate change and climate variability in Africa by including the effect of variations in land use on local climate. It concludes that the risk of malaria epidemics is likely to shift from the north to the south of the Sahel, and to highland areas previously free of the disease.

A new study has explored how cities can create a low carbon future by presenting an approach to stakeholder engagement that develops scenarios of an ideal city. Rather than projecting towards a low carbon target for the future, the study suggests that ‘backcasting’ to the present day from these scenarios may provide a useful goal-orientated approach to environmental planning in cities.

Trees and other vegetation have an important influence on urban temperatures. To explore these effects, Japanese researchers have built and studied scale models of tree-lined streets. This approach could help designers and planners create urban environments that are cooler during summer months.

New research on climate-driven reductions in Arctic sea ice has predicted that, by 2040 to 2059, new shipping routes will become passable across the Arctic, linking the Atlantic and Pacific oceans. An increase in traffic has implications for the ecosystems of this fragile area.

Research from the US helps paint a clearer picture of the extent of global sea level rise, by considering new satellite data on the Earth’s gravity. Its findings support reports of accelerating ice melt and suggest that most of the change in sea levels is caused by receding polar ice sheets and mountain glaciers.

Studies on fracking too often focus on its technical aspects, and not the wider environmental, economic and regulatory context needed for political decision-making, according to a review of existing research by a US researcher. The review provides a framework for understanding these complex issues that could benefit the fracking debate and decision-making about fracking more widely.

A new study has assessed the vulnerability of 571 European cities to heatwaves, droughts and flooding caused by climate change. The causes of vulnerability differ across Europe and the researchers say the results could be used to design policies to mitigate the impacts.

Rapidly rising sales of electronic goods could cause huge amounts of hazardous electronic waste (e-waste) to build up in developing countries over the next 10 years, a new study has concluded. Prompt action is needed to ensure e-waste is properly managed in emerging economies to protect the environment and human health.

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 new pomegranate-inspired design is the basis of a longer-lasting lithium-ion battery created by US researchers. They designed a battery with an anode made from ‘silicon pomegranates’, which doubles the amount of energy that can be stored compared to a standard carbon anode.

‘Dye-sensitised solar cells’ (DSSCs) are an alternative to traditional silicon photovoltaic (PV) cells. They have a number of advantages over traditional PV solar cells, including greater flexibility and lower manufacturing cost, but they are less efficient at turning sunlight into electricity. Taking inspiration from nature, new research has doubled their efficiency using pine tree-shaped nanotubes.

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.

A new oil-spill risk-management system has been developed by researchers, which shows the likely effects of a coastal spill on the environment and economic activities for specific locations. It provides maps of oil-spill risk through a web portal and could help decision makers and emergency-response authorities protect the local environment and businesses through targeted and efficient planning and responses.

In-depth soil information is increasingly required to achieve an array of environmental and economic goals. In particular, accurate estimates of soil carbon stocks are necessary to guide land-management practices and climate- related policymaking. To help meet this need, Australian scientists have developed a new sensing method to analyse cylindrical soil samples (soil cores), known as the Soil Condition ANalysis System (SCANS). By integrating a novel automated soil- core sensing system (CSS) with advanced statistical analytics and modelling, the SCANS provides a level of detail that is difficult to achieve with existing alternatives. SCANS is not only rapid, accurate and inexpensive1, but is likely to be a useful tool for farmers, land managers and policymakers, as the improved assessment of soil functions, structures and carbon stocks will facilitate more informed, sustainable decision-making.

Researchers use life-cycle assessment (LCA) as a tool to evaluate the environmental impact of products and technologies across their entire lifetime — from extraction of raw material to end-of-life (disposal or recycling). It is challenging to apply the conventional LCA method to new or emerging technologies, however, due to the sheer quantity of data needed for such studies. This study proposes a screening-to-LCA method that uses available data to systematically evaluate the performance of such technologies, and support the uptake of those that are most environmentally sustainable.

New research on climate-driven reductions in Arctic sea ice has predicted that, by 2040 to 2059, new shipping routes will become passable across the Arctic, linking the Atlantic and Pacific oceans. An increase in traffic has implications for the ecosystems of this fragile area.

A recent study has considered 21st century changes in shipping access through the Arctic Ocean along three potential new routes linking the Atlantic and Pacific Oceans. As the sea ice melts, it is possible that high-strength vessels will be able to sail directly through the North Pole by the end of the century, its results indicate.

Putting a price on carbon emissions from deforestation is unlikely to prevent tropical forests being cleared for palm oil production, according to a recent study. Additional measures should be included in climate policies to protect forests from increasing global demands, such as biofuels.

Researchers have identified a possible way of reducing the survival rate of the pine processionary moth, a destructive pine forest pest. Including patches of broadleaf trees in pine woodland could trick the caterpillars into pupating in soil that is unsuitable for their survival.

A new study suggests that, although the global terrestrial carbon sink remained relatively stable from 1990 to 2007, the effects of tropical forests were virtually neutral because CO2 emissions from deforestation offset their carbon sink.

A new study has identified the factors that cause deterioration of Mediterranean pine plantations, to develop a model of that can predict the risk of forest decline to help inform forests management strategies under a changing climate. It suggests that loss of needles is the most useful predictor of decline for the species studied.

A recent study has assessed how the choice and cultivation of native and introduced pine tree species affects the impact of insect pests and fungal diseases in Spanish plantations. Native maritime pine trees appeared to be more susceptible to insect attack, whilst non-native Monterey pines were more likely to suffer from fungal attacks. Thinning trees also had differing effects on reducing the effects of pests, depending on the tree species.

Over 20% more carbon could be being released by tropical peatlands than previously estimated, a new study suggests. The research highlights the large quantities of carbon lost to rivers from deforested and degraded peatlands in Indonesia, in addition to carbon released as CO2 gas.

The impacts of drought on European trees are of high concern, especially under a changing climate. New research has indicated that, if summers become continually drier, sensitive species, such as larch and spruce, will suffer reduced growth in some Alpine areas. This could potentially compromise ecosystem services provided by forests in these areas.

The North American pine wood nematode (PWN), Bursaphelenchus xylophilus, is a pest worm species that causes a disease known as pine wilt. It was discovered for the first time in the EU in Portuguese forests in 1999. Today, the entire territory of Portugal is demarcated for the presence of PWN, with a 20 km buffer zone, free from the pest, established along the Spanish border with the aim of preventing its further spread. The spread and establishment of PWN in the rest of EU territory is very likely if no strict measures are taken, as required by Decision 2012/535/EU of the European Commission, with serious economic and environmental consequences. To date, Spain has experienced five outbreaks of PWN, three of which have been successfully eradicated thanks to the EU measures and the effective work of the Spanish forest administration; and two outbreaks are currently being eradicated.

A new EC-commissioned study makes ten key policy recommendations for improving Europe’s competitive position within the eco-industries. As well as harmonising regulation and standards across Europe, the report recommends providing funding and skills development schemes specifically for the sector.

Locally managed carbon budgets for housing and transport could be highly effective in reducing greenhouse gas (GHG) emissions, according to researchers. They have suggested a policy framework with standardised methods to monitor city carbon budgets with local flexibility for remaining within these budgets.

Researchers have developed a new framework to assess the impact of land use policies on sustainable development in developing countries. The framework integrates environmental, economic, social and institutional impacts through the use of multiple influences and indicators identified by a range of stakeholders.

Resource productivity has become a popular indicator of environmental sustainability. However, new research has demonstrated that it is influenced by national income and its current use tends to support a simultaneous growth in economic productivity and resource consumption. In order to shape policy effectively, the study suggests that targets should directly emphasise resource consumption and emissions.

A recent international study has compared different Integrated Coastal Zone Management (ICZM) methods and suggests that improved enforcement and compliance would increase implementation of key strategies. It also highlights the potential for environmental impact assessments (EIAs) to develop science and policy integration.

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.

A pilot Marine Spatial Planning (MSP) project in the UK has found MSP to be a useful approach in managing marine waters sustainably. Sharing the knowledge and experiences gained in developing the Shetland Islands’ Marine Spatial Plan (SMSP) can help other authorities in the process of developing similar plans, says the project team.

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.

Collecting, or ‘harvesting’ rainwater may help society cope with a number of problems, such as water shortages, flooding and the degradation of urban streams. Urban roofs make up about half of the total sealed surface (‘unnatural’ surfaces, which cover over natural surfaces, such as soil) in cities and contribute the most to stormwater run-off, which could be harvested for other purposes. To maximise this potential, it is useful to know which type of roof can harvest the greatest amount of good quality water.

An earthquake that killed nine people in Lorca, Spain, last year could have been triggered by groundwater being drained from the area for use in irrigation, according to scientists. The study found that the ground moved in the same places as subsidence has been occurring since the 1960s, due to the extraction of groundwater.

A new study has shown that agricultural products make the largest contribution to the water footprint of the EU and recommends reducing food waste, changes in diet and increased agricultural efficiencies. On average, each EU citizen consumes 4,815 litres of water per day, when the water used to produce all goods and services, including those imported into the EU, is accounted for.

As part of the EU’s Blueprint to Safeguard Europe’s Waters1, a new study from the Joint Research Centre has mapped the water requirements of livestock across Europe for 2005. The maps and data can help quantify total European water use but also inform sustainable management by making use of ecosystem services (ESSs).
