The scope of ecotourism to finance national park conservation
How can ecotourism be managed so that tourists´ visits are compatible with the protection of species and their habitats? In a new study, researchers developed a tool to calculate the trade-off between tourism and the protection of an endangered bird in an Austrian national park, in order to optimise conservation and visitor management.

Effects of congestion charging increase over time
Congestion charging in Stockholm has become more successful over time, according to a study by Swedish researchers. Although the total cost of a journey that enters the congestion charge zone has fallen in real terms since the charges were first introduced in 2006, there has consistently been around 29% less traffic within the zone, compared with levels in 2005.

Global web of food trade complicates contamination tracking
The growing complexity of the global food trade network means contamination spreads more efficiently and is more difficult to trace. Increased data capture and sharing is recommended by a new study to help prevent food poisoning outbreaks and allow sources of contamination to be quickly identified.

Effective saltmarsh restoration must account for previous land use
Saltmarsh restoration can contribute to a range of ecosystem services but, according to new research, the effectiveness depends on previous land use. To optimise restoration, more research is needed on the effects of previous land disturbance on the delivery of ecosystem services and the relationships between physical, biogeochemical and ecological processes.

Lower diversity of soil organisms in new farmland
Converting grassland to arable land can reduce the diversity of nematodes, predatory mites, earthworms and enchytraeid worms in the soil, according to a study by Dutch researchers. However, they found that restoring arable land to grassland did not fully restore the diversity of these four groups during the course of the four-year study.

Parallel parking improves air quality on urban pavements
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.
