Urban planning must account for its effects on ecosystem services
Tightly compacted cities can increase flooding risk for local residents, but sprawling, suburban development can lead to major losses in carbon stored by the land and agricultural production. These are the conclusions of a study which explored the effects of different urbanisation patterns on vital ecosystem services.

Soil water repellency could change soil's ability to sequester carbon
Extreme events, such as droughts and prolonged dry spells, under climate change could increase the water repellency of soils, according to a recent study. In the long-term, this could reduce the capacity of soils to sequester carbon.

Forest density is increasing
The increased density of forests has been responsible for substantially increasing sequestered carbon in Europe and North America over the past 20 years, according to a recent study. The researchers suggest that managing forests for increased density offers one means of increasing carbon stocks.

Scientists assess environmental impacts of bioenergy for transport
Converting algae into bioenergy is one option being considered to meet future demand for transport energy. However, a recent study suggests that some combinations of cultivation processes and conversion technologies for algae-derived energy consume more energy than is produced, although water use and greenhouse gas emissions are lower for the most promising options compared with bioenergy sourced from switchgrass and canola.

Europeans exceed 'fair share' of global cropland use by 30%
Each person in the EU consumes the equivalent of 30% more global arable land than can be considered sustainable, according to a new study. As well as providing food for a growing population, the land is also increasingly used to grow biofuel crops.

New bubble-based technique for leak detection at CCS offshore sites
Better methods are needed to monitor underwater gas leaks. A new study outlines a technique that uses sound to detect bubbles of escaped gas and could help produce more accurate measurements of gas leakage rates from carbon capture and storage (CCS) sites, pipelines and natural leakage sites.
