Shale gas: independent planning is key to reducing environmental impacts of fracking

Funding for scientists, planners and inspectors should be available before any shale gas development begins, a new review recommends. As revenue for such staff is often provided by the development itself, planning, which is vital to provide immediate environmental protection as well as monitoring long-term impacts, is neglected. The researchers also advocate the use of 'adaptive management' as a decision-making framework for this complex issue.

Female fish swap sex in polluted, low-oxygen water

Hypoxia – low levels of dissolved oxygen – can cause genetically female fish to develop into males, new research has found. Hypoxia in aquatic environments is often the result of eutrophication, which is caused by pollution from human activities. The findings suggest that hypoxia could cause fish populations to collapse, with consequences for entire ecosystems.

Complying with emissions regulations: calculating the acid plume from ships’ desulphurisation equipment

Marine diesel contains sulphur compounds, which generate sulphur oxide (SOx) pollution and acid rain. Ships can use mitigating technologies to reduce their SOx emissions, but these can also have a negative environmental impact. The International Maritime Organization (IMO) introduced stringent legislation to control these, aspects of which are incorporated into EU policy. This study examined the implications of the IMO’s policy and recommends a number of design solutions to help ships comply.

Petroleum industry’s freshwater use puts pressure on areas with water scarcity issues

The impact that national energy sectors have on international freshwater resources has been demonstrated in the first global study of its kind. The analysis of 129 countries showed differences between countries and sectors in their reliance on international freshwater resources. For example, although the petroleum industries of North America and China are similar in magnitude, the North American industry consumes three times as much international freshwater. Demands from economically developed countries on less economically developed countries, which may have pre-existing water-scarcity issues, compound these problems and complicate the creation of policies that ensure both water and energy security.

Low oxygen levels affect reproductive function in female fish – across multiple generations

Low oxygen levels (‘hypoxia’) are a pressing concern for marine and freshwater ecosystems worldwide, and this may deteriorate as ocean temperatures rise. Hypoxia causes stress in organisms, which can cause reproductive impairments that persist across generations — even the offspring that have never been exposed to hypoxia. Previous studies discovered that hypoxia can disrupt sex hormones, resulting in birth defects and affecting reproduction of male fish over several generations. This study shows how hypoxia can also affect female marine medaka (Oryzias melastigma) over multiple generations — and thus may pose a significant threat to the sustainability of natural fish populations worldwide.
