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.

A free online system for assessing the sustainability of buildings is due to be launched across Europe in July this year. The tool captures scientific complexity whilst being accessible and easy-to-use, its developers say.

Green spaces in cities can have a cooling influence which helps reduce the ‘urban heat island effect’. New research from Portugal has demonstrated that even a small community garden can provide a significant cooling impact that can help efforts to adapt to climate change.

Coastal wetlands can substantially reduce erosion, property damage and human deaths in the face of rising sea levels and severe storms, recent research concludes. Understanding whether wetlands can provide effective coastal protection is essential to developing effective climate change adaptation strategies.

Greenland’s four major glaciers could contribute 19 to 30 mm to sea level rise by 2200, according to a new study. The researchers developed a sophisticated model which provides new insight into the effects of climate change on Greenland’s glaciers, by capturing the complex processes involved in their movement and melt.

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.

A measure of ‘chemical footprint’ is being developed by researchers to assess the environmental impacts of the toxic chemicals released by the production and consumption of goods. The methodology, based on life cycle and risk assessment, is also designed to be linked to the resilience of ecosystems to chemical exposure.

A community-level initiative in the UK has successfully used social marketing techniques to encourage participants to reduce their greenhouse gas emissions. On average, participants reduced their emissions footprint by 2 tonnes every year. Based on the initiative, the authors of this study propose a framework to guide future community engagement.

The largest ice sheet in the world, the east Antarctic ice sheet, may succumb to climate change faster than thought, according to recent research. Warming ocean currents, triggered by shifting wind patterns, could accelerate melting of the ice sheet, leading to a rise in sea levels, say the researchers.

Deep-water fish living along the Irish-UK continental slope remove more than a million tonnes of CO2 from the atmosphere each year, according to a recent study. Continental slope ecosystems play an important role in carbon sequestration, which should be considered before exploiting deep-water resources, say the researchers.

Rising levels of atmospheric CO2 will increase the severity of wheat diseases, reducing yields and threatening food security, a new study suggests. Researchers found that levels of two common wheat diseases increased significantly when plants were grown with elevated CO2. Furthermore, disease levels were even worse when the plants and pathogens had been acclimatised to the higher concentrations of CO2 beforehand.

While extreme environmental events — such as floods and tsunamis — may trigger migrations, the underlying drivers of migration are far more complex and diverse, says new research. The research reviewed the available evidence on population movements associated with extreme weather events and found that people could find themselves ‘trapped’ and vulnerable, whether they stayed at their homes or moved to new locations.

The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening soil moisture conditions in the basin over the course of the century.

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

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.

Spanish medical and public health researchers have found no clear evidence for increased heavy metal levels in adults living near a recently-built urban solid waste incinerator over two years of operation. Concentrations of lead, chromium and mercury in blood and urine samples taken around the plant were not significantly higher than for populations who lived further away.

A recent study has examined how ships no longer economical to run are broken apart, reassembled and made into goods of new value, such as furniture, in Bangladesh. There are strong concerns about working conditions for those who work in this industry and ship breaking yards have recently been closed as they are considered hazardous. However, this study draws a valuable lesson from ship breaking in that 'things are but temporary configurations of material', which can, potentially, be endlessly reassembled, under safe conditions.

Waste management policy in the EU is successfully reducing the proportion of waste that is sent to landfill and cutting greenhouse gas (GHG) emissions caused by inefficient waste management, according to a new study. However, the study also supports greater efforts channelled into waste prevention.

Vastly increasing amounts of waste electrical and electronic equipment (WEEE) are being produced in Europe. Researchers have taken an in-depth look at how Spain has dealt with its electronic waste over recent years, and provide some guidance to other countries developing their own management practices.

Recent research reveals that even remote areas of the oceans are affected by increasing levels of plastic waste on the seafloor. The study found that quantities of litter from human activities, mostly plastic, on the seabed of an isolated Arctic site doubled from 2002 to 2011.

The challenge of measuring the ‘absence of waste’ makes it particularly difficult to monitor and evaluate waste prevention policies. Researchers have examined the strengths and weaknesses of nine methods of assessing waste prevention, and recommend a hybrid approach, which combines the best of many methods, as particularly valuable.

Over a third of all food waste in Sweden is avoidable, according to new research. If such waste minimisation were achieved, there would be less potential for biogas production, but the researchers suggest that this does not represent a compromise because it is currently performed on only a very small amount of waste food.

Eco-innovations which help prevent the production of waste are explored in a recent German study. It considers the drivers and barriers to the uptake of material efficiency measures in businesses, green procurement and product leasing schemes.

The land use associated with food imports to Germany outweighs that of exported food, leaving the country with a 'land debt', new research suggests. However, reducing the amount of animal products in the diet and minimising food waste could enable the country to achieve a positive land balance, the researchers conclude.

Researchers have designed and proposed a new organic waste management plan for Catalonia, Spain, and presented it in a recent study. They say that the plan would reduce a number of environmental impacts that arise from landfilling biodegradable waste, including natural resource depletion, acidification, and eutrophication.

Turkey is a major ship recycling centre and is the largest OECD member country with a significant ship recycling industry. In this study, researchers reviewed the environmental, health and safety issues surrounding the Turkish shipbreaking industry, its compliance with environmental regulations and its ability to claim ‘green recycling’.

Recycling waste from farming and mining could help improve the sustainable use of phosphorus, a recent study suggests. The study traced the stocks and flows of phosphorus over a 50 year period to reveal changing patterns of global phosphorus use. The results can be used to develop the sustainable management of phosphorus — a finite and critical resource — in the future.

Recycling has significant environmental benefits and is key to a circular economy. The EU has set a goal for Member States to recycle 50% of their municipal waste by 2020 and plans to set a 65% target for 2030, although progress towards this goal is variable. This study assessed a waste separation scheme in Malta, a Member State with traditionally low levels of recycling. Even though mixed waste was collected more frequently and for free, residents contributed to the voluntary recycling scheme, with participation increasing over time. This study provides useful insights for developing voluntary policy approaches.

Scientists have tested the behaviour of biodegradable plastics in managed composting and anaerobic conditions, as well as under simulated environmental conditions, such as in seawater or soil. This study found that blending different types of biodegradable plastics may open up new opportunities in relation to their end-of-life treatment — notably the potential to make one of the world’s best-selling biodegradable plastics, polyactic acid (PLA), home-compostable by blending it with another polymer (polycaprolactone — PCL). However, the researchers were also concerned that most materials tested could still cause plastic pollution as they failed to biodegrade sufficiently — and, in some cases, not at all, in particular, in soil and the marine environment.

City children who spend lots of time in green spaces, such as parks, and at the beach are less likely to have emotional and social difficulties, indicates new research from Barcelona. The study of over 2000 children supports theories that green and blue infrastructure have benefits for our health and wellbeing.

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.

The $192 billion IT-BPM industry body has informed the Ministry of External Affairs (MEA) about the critical talent from various member companies such as Tata Consultancy Services, Infosys, Wipro, HCL Tech, Startek and many others being stranded and they should be considered for evacuation.

IT firm says margins to remain under 16-17%, sees a $50-70-million hit from ransomware Maze attack

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 nanoscale 3D printing technique could be useful for nanomanufacturing processes with environmental applications. The authors of a new study have found a way to control their printing process by incorporating a simple pattern into the printing surface. They say their technique could reduce costs for nanoscale printing.

This Thematic Issue provides a flavour of recent work by scientists in the area of biodiversity monitoring to highlight both up-to-date approaches to conservation and evaluation, and how long-term monitoring data could be used more effectively in management and policy decisions.

A new study provides clues as to which innovative low-carbon technologies will successfully get onto the market quickly. The historical analysis of 16 energy technologies — from steam engines to wind power — found that the average length of a product’s ‘formative phase’ is 22 years. This important period of innovation in a technology’s development is shorter for products which do not need extensive new infrastructure or changes to user behaviour. The findings could help policymakers identify new technologies that can be deployed more rapidly to meet short-term environmental targets.

A new screening tool to assess the potential seismic risks (earthquake activity) from deep geothermal energy projects has been outlined in a recent study. The tool provides categories of seismicity risk for projects, which are dependent on factors including geological aspects, as well as social concern and location in relation to urban areas.

A new review of the potential uses of visual soil evaluation (VSE) shows how this tool can be used to indicate risks of erosion, compaction, greenhouse gas emission or storage and surface-water run-off. Assessing soils in this way is not only useful for agriculture, but has implications for the wider environment, due to the vital role that soil plays in the provision of ecosystem services, for example as a habitat for biodiversity and as a carbon sink.

As well as providing renewable energy, wave farms can help protect coasts against erosion by reducing the force of waves. However, it remains unknown whether they can provide this complementary service under future climate change when sea levels will be higher. A new study, based upon computer simulations, concludes that a wave farm off the south coast of Spain could indeed protect the coastline under higher sea levels, and cause the local beach to grow in size after storms.

As enterprises struggle through the pandemic, CIOs role need to evolve into a larger role of Chief Information Digital Officer

A remote consultation app at Apollo is allowing safety for both the patients and the frontline doctors while using AI to improve diagnostics.

The international University of California, Riverside-led SpARCS collaboration has discovered four of the most distant clusters of galaxies ever found, as they appeared when the universe was only 4 billion years old. Clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars, as well as hot gas and mysterious dark matter. Spectroscopic observations from the ground using the W. M. Keck Observatory in Hawaii and the Very Large Telescope in Chile confirmed the four candidates to be massive clusters. This sample is now providing the best measurement yet of when and how fast galaxy clusters stop forming stars in the early Universe.

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is gusty and turbulent. But near the sun where it originates, this wind is structured in distinct rays, much like a child's simple drawing of the sun. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.

The use of important ecosystem services, such as carbon storage or hunting, can be estimated through ecosystem accounting methods, a new study demonstrates. The researchers tested models that could help policymakers to understand the capacity of ecosystems to generate ecosystem services, and how these services are used over time.

Ecosystems services — the benefits that nature provides to people — are inadequately accounted for in Environmental Impact Assessments, a new study suggests. The researchers used a case study in France to illustrate the substantial economic losses that are incurred as a result of infrastructure development that goes ahead without sufficient consideration of the impacts on ecosystem services.

The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods.

The U.S. prison population continued to rise even after the crime rate began declining in the mid-1990s because judges were faced with more repeat offenders, a new study suggests.
