An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.

In theory, payment for environmental services (PES) is a market mechanism but, in practice, it depends on intervention from the state or community. This is the conclusion of a new review of case studies that indicates that PES relies on public bodies and communities to act as intermediaries in the trading of services.

Payments for Ecosystem Services (PES) schemes offer direct payments for communities and individuals in exchange for conserving areas of land reserved for conservation for their environmental qualities. The results of an Ecuadorian study highlight key aspects for designing successful PES schemes and demonstrate how investments associated with PES can also benefit poor communities.

Researchers have developed a new approach for identifying regions that are most suitable for expanding ecosystem services. This could be used to help inform spatial planning decisions. By modelling ecosystem services’ opportunity costs in relation to agricultural revenue, the study provides a map of suitable areas of ecosystem service expansion in Eastern Europe.

The cost of a Mediterranean marine protected area (MPA) network could be cut by over two thirds if countries surrounding the Sea collaborate in its creation. This is the conclusion of a study that explored how the Convention on Biological Diversity’s goals to protect wildlife through MPAs could be met cost-efficiently.

Water and carbon dioxide (CO2) can be converted into ‘solar thermochemical fuel’ using energy from the sun and very high temperatures. A new study has analysed the production of this fuel and found that, under favourable future conditions, costs could be as little as €1.28 per litre, with close to zero life-cycle greenhouse gas (GHG) emissions. Although suitable as a substitute for any hydrocarbon fuel, it could be particularly useful as a much-needed alternative for energy-dense jet fuel.

Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes.

Speed control, road traction, wipers when it rains, maintaining safe distances, collision avoidance, and lane change are some of the prominent features.

Curefit, which has come under fire from several of its staff that were laid off, is one of the many startups whose business has been directly impacted due to the virus outbreak

Better fuel economy, lower emissions and longer driving ranges are important factors for people considering the purchase of alternatively-powered vehicles (APVs), new research suggests. The German study also found that people would consider paying more for an APV if they could enjoy vehicle tax exemptions, free parking or bus lane access.

Transport policies that produce physically segregated cycle lanes on main roads, combined with low-speed local streets, will boost numbers of cyclists and provide the best financial return on investment, new research suggests. Using Auckland, New Zealand as a case study the researchers showed that the economic benefits of this policy can outweigh the costs by more than 20 times.

Large imports of low-cost Russian wood to Finland up until 2007 increased pressure on Russian forest ecosystems, whilst reducing harvest pressure on Finnish forests and those of other European countries that consume wood-based products made in Finland, according to research. This highlights the need to take the international dimension of environmental impacts into account when designing sustainable production and consumption policies.

A new international policy regime for sustainable forest management may complicate matters rather than provide solutions, according to a new report. It suggests there should be better co-ordination of existing hard and soft policy options and between the numerous organisations involved in forest management.

International trade in wood and wood products affects forest stocks around the world. A recent study examines the relationship between changes in forest cover and international timber trade at global level. If finds that some wealthier nations with low population density can maintain forest areas while exporting wood; but other, usually poorer, nations, are losing forests through domestic and global demand for wood.

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.

A recent study has found that fire regimes have changed in Spain over the past 42 years. The pattern of changes has affected the number of fires and burned area, reflecting a changing climate and environmental conditions, such as land use changes caused by a population shift from rural to urban areas, and modern fire suppression activities.

A new study has examined how recent policy developments, such as the EU Habitats and Water Framework Directives, have resulted in wider and more integrated management of river estuaries, using the Severn Estuary in the UK as a case study.

Researchers have evaluated how well Swedish policy instruments deal with external environmental costs associated with district heating (DH) plants. They found they have improved environmental performance, but for some plants, the costs of internalising external costs, in terms of taxes, emission permits and environmental fees, are higher than the environmental costs of pollution they produce.

Sustainable de-growth is the transition to a smaller economy with less production and consumption. A new study has explored its origins and compared it to sustainable development. The study found that to become a viable alternative to sustainable development, ‘de-growth’ needs to be more clearly defined, and its implications for employment need to be considered very carefully.

A recent study has investigated how the relationships between a company’s owners, managers and boards of directors may influence its environmental performance. The findings indicate that environmental performance is higher in companies with powerful CEOs, who are also chairpersons on their board of directors.

Human migration as a result of climate change is now a reality. People across Africa, Asia and Latin America are moving in response to unpredictable rainfall patterns. The governments of Bangladesh, Papua New Guinea and small island states, such as the Solomon Islands, have already had to resettle people because of rising seas. A recent policy brief, published by the Institute for Environment and Human Security of the United Nations University, examines this issue and makes recommendations for policy.

Effective risk governance is important when developing new technologies. This study assessed the approaches to governance of nanotechnology in Europe, based on a comprehensive review of literature and practices, complemented by discussions with key stakeholders. The study provides a new analytical framework for exploring the strengths and weaknesses of governance strategies and makes recommendations specific to nanotechnology.

The uncertain economic climate has severely affected companies’ decisions on whether to renew Eco Management and Audit Scheme (EMAS) certification in Spain, a recent survey indicates. The study suggests that a company is less likely to renew if initial certification was mainly motivated by government subsidies and grants than if certification is believed to improve business performance.

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.

The management of international rivers is subject to two main types of boundary: the physical boundary of the river itself and the socio-political boundaries of the nations and regions that surround it. A new study has compared the impacts of managing rivers according to these different boundaries in Europe and Africa.

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.

A new study has compared the water governance and management systems of nearly 30 river basins around the world. Results indicated that governance systems with distributed political power and good co-ordination help to implement the principles of good governance in water management practice, and to adopt more advanced climate change adaptation policies.

By 2070, there may be insufficient water for irrigation to ensure yields and profitability for some crops currently grown in northern Germany - if the IPCC´s worst case climate change scenario becomes a reality - new research warns. To reduce future demand for water under a changing climate, the study suggests that farmers grow different crops and change their management practices.

Unusually warm or cool Pacific sea surface temperatures, known as El Niño and La Niña, can be used to reliably predict anomalies in flood risk for river basins that cover 44% of the Earth’s land surface, a new study has shown. The researchers also quantified overall flood damage by combining information on flood risk with estimates of damage to economies and numbers of people at risk. This could help improve flood disaster planning, they say.

Loss of satellites providing rainfall data could have a negative effect on global flood management, according to new research. However, this could be mitigated by improved international co-operation and the use of more modern satellite technology, the authors say. The study examined the consequences for flood management of the loss of four of the existing 10 dedicated rainfall measuring satellites.

The English Channel (La Manche) is one of the world’s busiest sea areas, and management of it is a challenging task. This study reviews governance across the Channel, finding poor integration between countries, sectors, policies and research. The study also considers management in terms of the ecosystem approach and suggests that linking research between the UK and France could be key to improving marine governance.

A pilot cloud-based learning platform that brings together multiple datasets, models and visualisation tools has been developed with the engagement of numerous stakeholders throughout the design process. This tool could lead to informed decisions about flood risk at the local level. These types of tools and frameworks are effective ways of facilitating better decision making.

In the face of substantial evidence that modern land use management practices have increased runoff at the local scale, a new study reveals changes in local land use management practices can reduce the risk of local flooding. However, there is little evidence so far that these local increases in runoff culminate in large-scale flooding effects. To address this lack of evidence, the researchers present a model that maps the downstream rate of flow back to its source areas.

A recent study has analysed research on implementing the Water Framework Directive (WFD) in Europe and identified a number of research gaps that could be filled. For example, some countries, such as Hungary, Romania and Slovakia, have not been well studied and more research on the experiences of such countries would build up knowledge on the implementation of the WFD across Europe.

Throughout Europe and beyond, the delivery of flood risk management (FRM) is increasingly being seen as the shared responsibility of governmental actors and citizens. However, a new study, which explored the viewpoints of stakeholders in a flood-prone part of Belgium, found that citizens see FRM mainly as the government’s responsibility.

As the climate becomes more volatile, managing the risk of flooding has never been more important. This study proposes a new framework for evaluating how flood risk is managed by governments, which is applied to reveal the strengths and weaknesses of the system in England. The researchers say their approach can help to improve flood-risk governance and could be applied to other countries as well as other types of hazard.

A new study has looked at the potential of green infrastructure to compensate for the effects of soil sealing generated by urban development. It investigates how green roofs and permeable paving could contribute to flood mitigation in southern Italy. Using a hydraulic model technique, the researchers found that, in this particular urban case, green roofs were more effective than permeable paving. Policies to promote the adoption of sustainable urban drainage systems (SUDS) by the private sector could thus prove more effective under certain circumstances, and policymakers should look at ways to promote SUDS where suitable.
