Traffic noise pollution mapped with new mobile phone app
A new mobile phone application which can help monitor traffic-noise exposure is presented in a recent study. The app, '2Loud?', can measure indoor night-time noise exposure and, given large-scale community participation, could provide valuable data to aid urban planning, the researchers say. In an Australian pilot study, nearly half of participants who used the app found that they were exposed to potentially unhealthy levels of night-time noise.

Mountain grasslands and shrublands store significant amounts of carbon
Despite their general absence from climate policy discussions, the world's mountain grasslands and shrublands (MGSs) store between 60.5 and 82.8 billion metric tonnes of carbon, a new study estimates - more than three times that of ocean and coastal ecosystems. This research, which is the first to provide a global inventory of carbon stored in MGSs, argues that these ecosystems should be accounted for in climate policy.

Water demand for crops may rise in northern Germany under warmer climate
By 2070, there may be insufficient water for irrigation to ensure yields and profitability for some crops currently grown in northern Germany - if the IPCC´s worst case climate change scenario becomes a reality - new research warns. To reduce future demand for water under a changing climate, the study suggests that farmers grow different crops and change their management practices.

Cost-benefit-analysis use limited by lack of belief and fears of loss of influence
Reluctance to use cost-benefit analysis (CBA) in environmental decision making in Germany stems from a preference for traditional approaches and a fear that it leads to loss of influence. This is suggested by new research based on interviews with those responsible for water policy management.
