Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

Valuations of water quality as an ecosystem service often fail to include related services like recreation or human health, and do not consider the effects of water quality changes due to management. Researchers have now developed a template for valuation that considers multiple services and links management actions to changes in water quality and ultimate economic value.

Interactions between population growth, consumption and the use of natural products and services have created an unsustainable pressure on the environment. New research has provided a detailed investigation into the relationships between these three trends, providing insight into how to alleviate these pressures. It concludes they cannot be addressed by market mechanisms or technological advances alone.

Fire frequency is changing globally, yet it is unclear how such changes affect soil carbon and nitrogen storage, and, in turn, impact on ecosystem productivity. A study was conducted to evaluate how increased fire frequency drives changes in soil carbon and nitrogen over multiple decades. Data from 48 sites that have experienced altered fire frequency were analysed, spanning up to 65 years. The meta-analysis found that frequently burned sites experienced a significant decline in surface soil carbon and nitrogen over time — on average having 36% less carbon and 38% less nitrogen, after 64 years, than sites that were protected from fire. The researchers also observed comparable changes in an independent field dataset and in dynamic model simulations of global vegetation. The results indicate that future changes in fire frequency may lead to long-term changes in the amount of carbon and nitrogen stored in soils, especially in savanna grasslands and broadleaf forests. This has implications for the global carbon cycle and for ecosystem productivity and should, therefore, be considered in the design and implementation of relevant policy instruments.

A new study from Belgium has gathered community views of brownfield regeneration. Results indicate that the often overlooked aspect of landscape quality, such as green spaces, visually-attractive areas and cultural heritage, is important in people’s opinions of brownfield regeneration schemes.

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.

Urban green spaces provide important ecosystem services in cities, from recreation to the mitigation of noise and air pollution. This study quantified the ecosystem services (ES) provided by green spaces in Rotterdam, the Netherlands, using new methods to evaluate high-resolution land-cover data. The findings show that different types of green space provide different ES, highlighting the importance of careful design during city planning. The authors say their method to map ES supply will aid the design of healthy, climate-resilient cities.

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.

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 health risks to humans of using recycled water to irrigate crops needs to be carefully managed. New research has demonstrated that ‘managed aquifer recharge’ can be just as effective as conventional water treatments in improving the quality of recycled water for use in irrigation.

This method can help EU Member States monitor water under the requirements of the Water Framework Directive and the Marine Strategy Framework Directive.

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.

Valuations of water quality as an ecosystem service often fail to include related services like recreation or human health, and do not consider the effects of water quality changes due to management. Researchers have now developed a template for valuation that considers multiple services and links management actions to changes in water quality and ultimate economic value.

Population growth of any country is ultimately dependent on that country’s access to freshwater resources, which also determines its capacity to produce food. A new study shows that population growth is expected to decline in countries with low water resources, as water-rich countries reduce food exports in order to feed their own growing populations.

The impact of shale gas development on surface water quality has been explored in a recent study. Focusing on the Pennsylvania portion of the Marcellus Shale formation (which stretches from West Virginia to the Canadian border), the researchers conclude that shale gas wells and the treatment of shale gas extraction waste have measurable impacts on downstream surface water quality.

Research into future climate scenarios suggest that by 2100, climate change could lead to annual damages in the EU from river flooding alone of €14 billion to €21.5 billion, with more people affected than today, and a reduction in household welfare.

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).

Human water consumption has increased the frequency and intensity of periods of abnormally low flow in streams, new research suggests. The frequency of these events increased by 30% globally, largely due to use of water for irrigation, the researchers conclude.

Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems.

The number of earthquakes of magnitude 3 or greater in the central and eastern US has increased significantly in recent years, from about 21 a year between 1967 and 2000, to over 300 between 2010 and 2012. Most of this increase seems to be linked to the deep injection of wastewater in underground wells, according to a recent review of seismic activity.

Climate change adaptation measures could improve the security of some groups of society at the expense of others, a new study concludes. Climate change adaptation policies should be based on genuine democracy and investment must be fairly distributed, to ensure that all at-risk groups benefit equally, its authors recommend.

Changing agricultural management practices can significantly improve water quality, according to a long-term study. The researchers found that in a US lake the total amount of suspended sediment fell, and water clarity increased as a result of multiple integrated practices implemented to reduce runoff in the surrounding area. These included introducing buffer strips of vegetation and planting trees.

Marine diesel contains sulphur compounds, which generate sulphur oxide (SOx) pollution and acid rain. Ships can use mitigating technologies to reduce their SOx emissions, but these can also have a negative environmental impact. The International Maritime Organization (IMO) introduced stringent legislation to control these, aspects of which are incorporated into EU policy. This study examined the implications of the IMO’s policy and recommends a number of design solutions to help ships comply.

Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the pollution of marine ecosystems.

Water policies at European and French national levels have led to a clear improvement in the water quality of the River Seine, a new study has found. A significant reduction in phosphate and ammonium pollution and increasing oxygen concentrations are evident. However, nitrate concentrations are still higher than the recommended level for good freshwater status, despite substantial reductions of surplus nitrogen in agricultural soils over the past few decades. The researchers recommend strengthening current agri-environmental management measures to help the river to return to a fully healthy status.

Worldwide, programmes have been implemented to protect water quality from human pressures, often using ecological indicators as a method of evaluation. An eight-year study of a Portuguese estuary has found that indicators based on multiple measures of fish communities, such as the number and relative abundance of resident and migrant species, reflect human pressures on these transitional waters and could improve the implementation of water protection programmes.

Researchers have developed an online tool to help water managers find effective ways of tackling eutrophication, an excess growth of weeds and algae that suffocates life in rivers, lakes and seas. They describe the tool as quick and easy to use and understand. Users can compare the likely effects of different strategies for cutting nutrient pollution in surface waters via an interactive map-based system; this is currently available for Sweden and Europe as a whole.
