Considering the sustainability of the services provided by an ecosystem could help to overcome management challenges and hit water quality targets defined by the EU, says a new study. By exploring 13 of the ecosystem services (ES) provided by the Venice Lagoon, Italy, the researchers identify factors affecting sustainable and unsustainable patterns of ES provision, and suggest that confined and more open water bodies could benefit from different management strategies.

Big Tech firms have already sent in their suggestions to govt on creating awareness

Facebook said advertising revenue was roughly flat in the first three weeks of April compared with the same period last year

The company on Wednesday announced systems integration (SI) capabilities including consulting, agile devOps, cloud migration, cloud capacity optimization and the Future Mode of Operation aimed at taking the communications industry to the cloud at an accelerated pace.

While Amazon Web Services, or AWS, and Microsoft are restructuring some large contracts on a case-by-case basis, according to people familiar with the decisions, smaller companies aren’t receiving the same flexibility.

Amazon Web Services (AWS), the Cloud arm of retail giant Amazon has announced the third availability zone in its Mumbai Cloud Region.

This expansion adds up to 15 data centres under STT GDC India’s ownership and management, and increases the power capacity to more than 90 megawatt of critical IT load across eight cities, further strengthening its market-leading position, said the company.

According to researchers, opportunities for carbon sequestration and benefits for biodiversity offered by forest rehabilitation schemes mean they should be given greater value as a tool for carbon offsetting. A new study demonstrates the value of forest rehabilitation for rainforest birds.

It is important to have a single definition of 'ecosystem services', but a single classification scheme for services is not appropriate, according to researchers. There are many contexts in which ecosystem services can be used and the context should help to determine which classification scheme is the most appropriate for decision making.

New research has identified the areas in the Western hemisphere where climate change may have the greatest impacts on amphibians. Alongside traditional methods to predict shifts in geographical ranges, it mapped species with particularly restricted ranges and identified areas most likely to receive less precipitation in the future.

The fragmentation of habitats is a growing concern for nature conservation. Butterflies and moths are particularly sensitive and new research has shed light on what makes some species more vulnerable than others. Those that are less mobile with more specialist diets and less reproductive potential appear to be more affected by habitat fragmentation.

A new model, named OUTOPIE could help design more effective agri-environmental schemes. The model links the farm, field and landscape levels to allow a more accurate assessment of the costs of enrolling specific fields in conservation schemes. Using the model, the researchers were able to assess the cost-effectiveness of different policies for the conservation of the Little Bustard bird (Tetrax tetrax) in France.

A new study suggests that improving the quality of existing wildlife habitat is more important than creating new habitat, when attempting to counteract the negative effects of climate change on species survival. This suggests that resources would be better directed towards habitat rehabilitation and reforestation than building new habitat features.

There is a recognised need for a more comprehensive system to observe, track and compare biodiversity across the world. Three years ago a global network was established to help reach this goal. It has identified the necessary characteristics for such an integrated system and possible ways in which integration can occur.

The litter size of the endangered European mink is less than half of that of its main competitor, the invasive American mink, research shows. The higher fertility of the American mink may allow rapid population growth of this species, threatening European mink with extinction.

Urban waterways can provide foraging opportunities for a range of bat species. However researchers have found that bats in the UK are negatively affected by high levels of invasive plant species and urban development near waterways. The researchers highlight the value these often disregarded urban spaces can have for ecosystems, and suggest ways to improve the biodiversity of waterways.

Signs that the ranges of sub-mountainous forest plants in France have contracted in response to global warming have been detected in a new study. This pattern is likely to induce a splitting of these species’ ranges across Europe under future climate change, which could have serious consequences for plant genetic diversity and the capacity of plant populations to adapt to warming climates, say the researchers.

The risk of alien species introduction via trade in plants is higher if the plants are from poorly regulated countries with high forest cover, calculates a recent study. For introductions via the vehicle and timber trades, the risk is higher if the exporting country is politically unstable. These findings could help border controls focus their surveillance efforts on imports from countries with risky socioeconomic profiles.

The warmer, drier conditions expected under on-going climate change will reduce the rates at which soil fauna and microbes decompose plant litter, suggests new research from Germany. This may have important implications for agriculture and natural ecosystems worldwide, as litter decomposition is a key process in cycling and distributing nutrients throughout ecosystems.

Many agricultural pesticides used in Europe could disrupt male hormones and lead to infertility problems, according to laboratory tests. ‘Biomonitoring’ studies to investigate the actual behaviour of pesticides in the human body are now urgently needed to clarify the link between pesticide exposure and male reproductive health.

New research has provided the first conclusive evidence that microplastics ingested by marine wildlife can transfer toxic pollutants to their tissues. The researchers studied lugworms fed on PVC particles contaminated with either widespread marine pollutants or plastic additives and found that these 'earthworms of the sea' absorbed the chemicals into their gut tissue, which reduced their ability to perform essential functions.

The European eel could act as an indicator of the ecological quality of aquatic environments, according to a new study. The research suggests that new pollution limits could be developed based on levels of pollutants in eel muscle, with the aim of improving the ecological quality of water under the Water Framework Directive (WFD).

Lithium production has increased dramatically during the past decade. A new study has found that exposure of rainbow trout to lithium results in fast accumulation in plasma and the brain, along with decreased concentrations of ions such as sodium.

A growing body of evidence suggests that endocrine-disrupting compounds (EDCs) are contributing to declines in fertility. This case-control study found that EDCs were associated with changes to sex hormones and risk of subfertility in men. The researchers say environmental levels of these chemicals should be reduced to protect male fertility.

If the EU is to combat resource scarcity, it is necessary to develop and refine strategies for substituting raw materials with sustainable alternatives, such as recovered by-products from waste. A recent study presents a new approach for evaluating the sustainability of raw materials’ substitutions, based on the quantification of the embodied energy (energy required to produce the material from ores and feedstock) and carbon dioxide footprint (greenhouse gasses produced and released into the atmosphere during the production of the material) of both the raw material and its proposed substitute. The evaluation method has been applied to a real case, where it indicates that substituting a raw material (calcite) with stabilised fly ash for use as a filler in polypropylene composites in plastic manufacturing may be sustainable. The study also highlights the need for additional policy tools and legislation to encourage Europe’s transition towards a circular economy.

Soil biodiversity, soil quality, and soil health are integral to protecting the natural environment. Soils are crucial to food production and human well-being, as highlighted by the UN Sustainable Development Goals (SDGs). The abundance of soil biota is of great importance for the provision of associated ecosystem services (ES) and fundamental driver of self-regulation in soil. This study explores how the presence, or absence, of earthworms affects aspects of crop health and productivity, focusing on their shielding of winter wheat from the toxic plant fungi Fusarium.

If the effects of air pollution on climate change are included in air quality strategies, efficiency gains of €2.5 billion can be achieved in the EU, according to recent research.

New research suggests potential benefits in integrating air quality and climate change policy. It predicts that accounting for the climate impact of certain air pollutants in the EU, USA and China could complement policies designed to reduce the air quality impacts of these pollutants.

Recent research has investigated the effectiveness of air quality management at the regional level in Italy and found that some of the most commonly adopted measures do not always produce the highest emissions reductions.

Measures to reduce greenhouse gas (GHG) emissions have the additional benefit of reducing air pollutants. However, these benefits are rarely included in the design and evaluation of climate change policies. A new study suggests that considering these benefits in climate change policy could reduce the cost of such policies, and engage stakeholders who are otherwise unmotivated to tackle climate change.

Despite some criticisms about the Clean Development Mechanism (CDM), a new study has indicated that CDM projects in China could be making sizeable improvements to air quality. The research predicted, in particular, that the projects' associated SO2 reductions would make up 13-14 per cent of the reductions in 2010 towards the national target level.

Climate change is likely to significantly affect future air quality over Europe. According to a recent European study, climate change alone is likely to significantly increase ozone pollution in Europe and by as much as 50 µg.m-3 (micrograms per cubic metre) over central France in July by the year 2100, compared with 1990 levels.

A recent study has compared the impact of future power generated from large, central stations with power generated from smaller distributed generators (DG) in California on air quality. It concluded that although DG produces more emissions, its impact on air quality is likely to be smaller than central power stations due to complex interactions between air chemistry and transport.

A recent study assesses new methods for comparing and predicting air quality data in Helsinki, Finland and Thessaloniki, Greece, that significantly improve the capability to analyse and predict air quality in these cities. There are good indications that the methods could be applied to other European cities.

Pedestrians are exposed to different levels of pollution on the pavements depending on how parked cars at the roadside are arranged, according to the first in a series of new studies in this area. The researchers modelled different parking regimes and found that less pollution reached the pavement when cars were parked sideways on, rather than at an angle to the street. Their results may help urban planners design more pedestrian-friendly streets.

Global air quality will significantly deteriorate by 2050 unless further steps are taken to cut current emissions from human activities, according to recent research. Most people around the world will be affected by worsening air quality with hotspots of particularly poor air occurring in China, northern India and the Middle East.

New research has modelled the impacts of Athens and Istanbul in the eastern Mediterranean, on local and regional air quality. Results indicate that the impacts of megacity pollution vary significantly according to the time of year and that air quality improvements will require coordinated efforts within the eastern Mediterranean region and beyond.

To reduce air pollution levels in harbours, EU Directive 2005/33/EC requires all anchored ships to use fuels with low sulphur content. A recent study of air quality in Mediterranean harbours shows that levels of sulphur dioxide have decreased significantly since the Directive was implemented in 2010.

Predicting the effects of changing levels of atmospheric gases on agricultural crops is vital to ensuring food security under global environmental change. As well as yield, impacts on the nutritional value of crops must be considered. A new study has now shown that increased ozone decreases yields and increases the proportion of protein in the grain. Conversly, elevated levels of CO2 boosts wheat yields, but it also reduces protein proportion in two different ways.

Low emission zones (LEZs), which restrict access for high emission vehicles, have proven to be a successful way to improve air quality in line with EU regulations. An analysis of London’s LEZ has revealed discernible reductions in air pollution levels five years after implementation.

Some progress has been made towards improving air quality in Europe with levels of sulphur dioxide, carbon monoxide and benzene all falling substantially in recent years, a new report from the European Environment Agency (EEA) concludes. However, threats to human health and ecosystems remain, and urban citizens’ exposure to high levels of particulate matter (PM) and ozone are a particular concern.

Air pollution from the world’s megacities not only has local impacts, but can spread to remote regions of the world. Recent research has highlighted, for example, that megacities are a source of black carbon pollution in lowest kilometre of atmosphere in the Arctic, with European megacities contributing more than others.

Increased black smoke pollution was associated with increased mortality rates almost a month after exposure in a recent study. The researchers studied death rates in relation to pollution concentrations over a 22-year period in the city of Glasgow, UK, and found significantly higher mortality rates among residents at 13-18 and 19-24 days after increased exposure to black smoke.

Levels of the air pollutant PM_2.5 in Europe will continue to fall in 2020, concludes a recent study. Furthermore, deposition of nitrogen from air pollution will also drop. The outlook seems less positive for ground-level ozone, however, as large amounts of this pollutant continue drift over to Europe from other continents.

Real time monitoring of public health during two periods of high air pollution in the UK showed that there were an estimated 3 500 extra healthcare visits for acute respiratory symptoms and approximately 500 for severe asthma during these spells in 2014. The results of this research are presented in a new study which demonstrates the value of such ‘syndromic surveillance’ systems for exploring air quality’s effects on human health.

Greenhouse gas (GHG) inventories are significantly underestimating methane emissions from a region in the southwest of the United States, and potentially elsewhere, a new study has found. The authors of the study suggest that satellite data could be used to identify and quantify new sources of methane, such as fracking.

Emissions from well-regulated household waste incinerators do not reduce the quality of vegetables and milk produced nearby, a Dutch study suggests. Researchers found that levels of certain contaminants were similar whether vegetables and milk came from the area surrounding three incinerators, or from elsewhere in the Netherlands. They say biomonitoring programmes could offer a way to increase the understanding of the real impacts of waste incineration and to improve communication between waste management companies and local communities.

Ozone harms pollen viability of tomatoes, leading to reduced fruit weight, size and quality, a recent study has revealed. The researchers suggest the effect of ozone on pollen could be a useful way to rapidly test for pollution-induced stress on crop plants in risk assessments.
