We are all exposed to polluted air. Among main air pollutants are nitrogen oxides —the so-called ‘NOx ‘— and ozone , which cause irritation of respiratory tract and eyes, favouring cough, lung infections in children and asthma.

Air quality is not a local problem. Like clouds moving through the sky, pollution is transported from one location to another by wind patterns in the atmosphere .

Climate change influences water cycles. Particularly, it has an effect on the natural and socio-economic processes of river basins. Major rivers of the world have their origin in alpine-style mountains.

What happens to research findings once the researchers have gone away? A web site run from the University of Stuttgart in Germany offers scientists an opportunity to bring their own data from completed research project on environmental and health risks and contribute to an Integrated Environmental Health Impact Assessment System, dubbed IEHIAS .

Multiple disasters can have a cumulative impact leading to great human and financial loss. The awareness of all possible risks is of fundamental importance.

Twenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called "Cradle to Cradle" or "C2C" after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002.

Clean freshwater faces various threats such as increasing demand by population growth, pollution and changes in the hydrological cycle due to climate change.

Every day cities in Europe discard a useful nutrient-rich resource that could be used to grow crops. Ironically, we treat and process human wastes while we mine non-renewable phosphate and potassium and we consume fossil fuel to make nitrogen fertiliser.

Storm water is a critical consideration in managing urban water , as it influences the risks of flooding. Unfortunately, a global rise in urban population means that water management in urban areas is now under strain.

Jorge Marx Gómez is professor and chair of business information systems at the Carl von Ossietzky University Oldenburg , Germany. He was the scientific manager of the EU-funded project OEPI , completed in 2012.

There are 19 countries in the catchment area of Danube River. The extensive use of water resources in that area has not been without consequences on its water quality. Let alone on the riverside’s biodiversity and environment.

One litre of sea water contains about one billion bacteria.

Making decision that may affect the environment is not that simple. For example, if a EU policy maker believes that biofuels can reduce CO 2 emissions.

Coastal areas offer great challenges when balancing the need to protect natural habitats, with the requirement of human and economic activities . Dikes, for example, may not constitute the solutions of the future.

Vehicles seats are normally made of polyurethane foam, a thick material that is expensive to recycle and ends up in dumping sites or being incinerated.

How can policymakers change the way people think? This is what the InContext project, funded by the EU, hopes to answer. Leading European research institutions in the fields of transition, behaviour and sustainable development are trying to create a manual for change.

The amount of nitrogen that is excreted by livestock is directly proportional to the amount it is fed . This is according to Chris Reynolds a researcher in nutritional physiology of ruminants  at  the University of Reading , UK.

Dealing with sludge is one of the biggest issues of waste water treatment.

With climate change, flora and fauna shift their seasonal inner clock.  For example, fruit tree blossom earlier than previous years.

Nobody knows the underlying biological mechanisms of the European eels migration . Thanks to an EU-funded research project called eeliad , now about toreach completion, biologists have revealed some of its secrets, including a better understanding of its biology and migration route.
