Possible long-term effects of aircraft noise on children’s cognition

Companies that adopt the environmental management system ISO 14000, designed to help reduce businesses’ environmental impacts, generally back this up with sincere investment in environmentally-friendly practices, research suggests. Researchers found that adoption of the ISO 14000 was not ‘greenwash’, but reflected a move towards more sustainable practices in both European and North American companies.

Significant economic effects of climate change on European timber industry

The impact of climate change on the distribution of tree species is likely to have economic implications for the timber industry. A new study has estimated that climate-induced shifts in range could reduce the value of European forest land for the timber industry by between 14 and 50% by 2100. At the higher end of this estimate, this could equate to a potential loss of several hundred billions of euros.

Management of rice paddy fields affects greenhouse gas emissions

How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to minimise the release of methane and nitrous oxide.

Intensive grassland farming could have deep effects: sequestering significantly less soil carbon

Huge amounts of soil carbon have been discovered up to 1 metre below grassland in a recent UK study. Yet most carbon inventories do not assess soil deeper than 30cm. Furthermore, this research suggests that intensive management of grassland, involving high rates of fertiliser use and livestock grazing, may deplete carbon at these depths.

Dutch study shows policy effective in reducing packaging

Policies to reduce packaging are effective as long as they remain in place for at least five years and aim for an absolute reduction in packaging volume, experiences from the Netherlands suggest. A study of Dutch packaging policy found that packaging levels fell when such policies were in place, but that the amount of packaging has since risen as policies have become more short-term and focused on reducing packaging levels relative to changes in GDP.

How does living with aircraft noise affect wellbeing? A study of UK airports

Airports are associated with air and noise pollution and may, therefore, reduce the quality of life of local people.

Planting forests at high latitudes can have a cooling effect

A new study based on high-resolution satellite observations of forests suggests the 'albedo', or reflectivity, of a forest needs to be carefully considered in afforestation schemes designed to mitigate climate change, i.e. carbon balance alone is not a good indicator of mitigation value. The authors argue that the Kyoto Protocol carbon accounting rules grossly overestimate the cooling caused by afforestation, because they do not consider albedo effects.

Wildfires destroy protective effect of forest roots on soils

Forest root systems increase soil strength and stability, thus protecting mountainous regions against gravitational natural hazards, such as landslides. However, tree roots are affected by factors such as soil properties, climate and disturbances, such as timber-harvesting or wildfire — and, as a result, a forest’s stabilising effect can vary greatly. This study of fire-disturbed beech forests explores how this effect changes over time. The results reveal that forests which have suffered moderate and severe wildfires completely lose their protective function within 15 years, placing those regions at high risk of landslide for up to 50 years after the fires.
