Ticking ecological time bombs: Risk characterisation and management of oil polluting World War II shipwrecks in the Pacific Ocean.

The Second World War in the Pacific has left a legacy of over 3800 wrecks on the ocean floor. These wrecks contain thousands of tons of oil and pose a risk to the marine environment. Estimates of current corrosion rates show many wrecks are at risk of structural collapse. However, the scale of threat posed by potentially polluting wrecks (PPW) to coastal ecosystems in the Pacific is largely unknown, due to the lack of data to inform risk. This paper presents a strategy aimed to prioritise, manage, and mitigate negative effects of oil spills posed by PPW in the Pacific, using an example in Chuuk Lagoon. Wrecks are assessed and prioritised by means of risk characterisation. Wrecks are surveyed using photogrammetry to assess hull integrity. Finally, recommendations are made for the production of bespoke management plans and risk reduction strategies that work towards safeguarding marine ecosystems and the livelihoods of coastal communities.

Policy recommendations for front-of-package, shelf, and menu labelling in Canada: Moving towards consensus.

Greater availability of low nutritional quality foods and decreased consumption of nutrient-dense foods have negatively impacted the nutrient profile of the Canadian diet. Poor diet is now the leading risk factor for chronic disease and premature death in Canada. To help consumers choose healthful foods, nutrition labelling is one policy tool for communicating relevant nutrition information. However, there are notable shortcomings with current nutrition labelling systems, which make it difficult for Canadians to navigate the complex food environment. Government action on nutrition labelling systems, including front-of-package (FOP), shelf, and menu labelling, is required. In May 2016, we hosted a consensus conference with experts from research, policy and practice to review available evidence, share experiences and come to consensus regarding the next best steps for action on nutrition labelling in Canada. In this paper, we examine the evidence, opportunities and challenges surrounding FOP, shelf, and menu labelling. We outline recommendations, emphasizing FOP, shelf, and menu labelling as part of a standardized, coordinated and multi-pronged strategy supported by a robust, evidence-based nutrition profiling system. Recommendations for monitoring adherence to regulations and participation of stakeholders to avoid conflict of interest in policy development, implementation and evaluation are included. Within a comprehensive strategy, these recommendations can help to improve the nutrition information environment for Canadians.
