Nutrient footprints of different food groups calculated

Carbon footprints are an established means of communicating one aspect of a product's environmental impact. New research suggests additional 'nitrogen footprints' for food products could give consumers a more informed choice and help reduce eutrophication in water. However, it warns that there are environmental trade-offs for some food groups, for example, oil products have a small nitrogen footprint, but a fairly large carbon footprint.

Clarifying the limits of European coastal waters

Researchers attempting to establish the limits of coastal waters in Europe have found that national declarations of coastal waters contain a number of inconsistencies regarding the definition from the Water Framework Directive. In particular, the national declarations over-estimated the area of coastal waters by almost 12% overall, which could affect the results of ecological assessments required by several major EU environmental policies.

Nitrogen pollution measures need tailoring to specific areas to ensure cost-effective results

New research has shown that policy measures in Denmark have successfully reduced total nitrogen loading to 10 estuaries by 39% in recent decades. However, to fully meet the targets of the EU Nitrates Directive and comply with the EU Water Framework Directive in a cost-effective manner, further mitigation measures must be tailored and focused to particular areas.

Different recycling approaches may be needed for urban phosphorus

Sustainable management of phosphorus requires better information on how it flows through the environment via consumption and waste. New research from Sweden has found that 40% of phosphorus released by Gothenburg to the environment is in sewage sludge and a further 40% is in incineration ash. This suggests that phosphorus could be recycled from solid waste as well as from wastewater.

Artificial wetlands on farmland help to prevent soil loss and recapture agricultural by-products

Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests.

Environmental impacts of ocean-energy systems: a life-cycle assessment

Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the devices, as well as improving mooring and foundations and deploying devices further out at sea, will help to further reduce the life-cycle environmental impact of ocean-energy systems, according to the study.

Rapid and significant sea-level rise expected if global warming exceeds 2°C, with global variation

The world could experience the highest ever global sea-level rise in the history of human civilisation if global temperature rises exceed 2 °C, predicts a new study. Under current carbon-emission rates, this temperature rise will occur around the middle of this century, with damaging effects on coastal businesses and ecosystems, while also triggering major human migration from low-lying areas. Global sea-level rise will not be uniform, and will differ for different points of the globe.

Groundwater use and irrigation can negatively affect the net atmospheric moisture and amplify water scarcity problems

Groundwater pumping and irrigation can disrupt natural atmospheric processes, affect the whole water cycle, and potentially worsen water shortages during heatwaves, a new study suggests.

The study shows how some of the most intensively water managed areas of Europe — such as the Iberian Peninsula — could be affected by extraction of groundwater during years when conditions are especially hot and dry, potentially amplifying water scarcity in already-stressed regions.
