Tobacco control challenges in East Asia: proposals for change in the world's largest epidemic region.

ABSTRACT: East Asia is one of the world's largest tobacco epidemic regions. Although several international studies have evaluated the status of tobacco control in this region, the findings have not been integrated with knowledge on domestic activities at the national and municipal levels. We analysed the current tobacco control situation in three East Asian countries, Japan, China and the Republic of Korea, using both international and domestic data sources. We collected data between 2008 and 2011 in each country according to the framework of WHO's MPOWER (Monitoring, Protect, Offer, Warn, Enforcement and Raise) approach for guiding implementation of the WHO Framework Convention on Tobacco Control. Analysis revealed that 37-53% of adult men were current smokers and that smoking prevalence among middle-aged men reached 63%. Less than 20% of male smokers plan to quit and the use of nicotine replacement drugs was 14% at maximum. Forty-six percent or more of men and 20% or more of women were exposed to passive smoking at workplaces and at home, respectively. Many tobacco industry activities remain unrestricted and prevalent. Our findings indicate an urgent need for the following set of policies: raise cigarette prices to increase the quit attempt rate, particularly among adult men; develop a multi-component quitting assistance system to provide adequate assistance for smoking cessation; implement effective smoke-free policies in workplaces and public places to reduce exposure to passive smoking; and rebuild the administrative structure to denormalise tobacco industry activities. The importance of these standard approaches should be reaffirmed by all tobacco control policymakers in East Asia.

Project description:BackgroundEffective conservation management of highly mobile species depends upon detailed knowledge of movements of individuals across their range; yet, data are rarely available at appropriate spatiotemporal scales. Flying-foxes (Pteropus spp.) are large bats that forage by night on floral resources and rest by day in arboreal roosts that may contain colonies of many thousands of individuals. They are the largest mammals capable of powered flight, and are highly mobile, which makes them key seed and pollen dispersers in forest ecosystems. However, their mobility also facilitates transmission of zoonotic diseases and brings them in conflict with humans, and so they require a precarious balancing of conservation and management concerns throughout their Old World range. Here, we analyze the Australia-wide movements of 201 satellite-tracked individuals, providing unprecedented detail on the inter-roost movements of three flying-fox species: Pteropus alecto, P. poliocephalus, and P. scapulatus across jurisdictions over up to 5 years.ResultsIndividuals were estimated to travel long distances annually among a network of 755 roosts (P. alecto, 1427-1887 km; P. poliocephalus, 2268-2564 km; and P. scapulatus, 3782-6073 km), but with little uniformity among their directions of travel. This indicates that flying-fox populations are composed of extremely mobile individuals that move nomadically and at species-specific rates. Individuals of all three species exhibited very low fidelity to roosts locally, resulting in very high estimated daily colony turnover rates (P. alecto, 11.9 ± 1.3%; P. poliocephalus, 17.5 ± 1.3%; and P. scapulatus, 36.4 ± 6.5%). This indicates that flying-fox roosts form nodes in a vast continental network of highly dynamic "staging posts" through which extremely mobile individuals travel far and wide across their species ranges.ConclusionsThe extreme inter-roost mobility reported here demonstrates the extent of the ecological linkages that nomadic flying-foxes provide across Australia's contemporary fragmented landscape, with profound implications for the ecosystem services and zoonotic dynamics of flying-fox populations. In addition, the extreme mobility means that impacts from local management actions can readily reverberate across jurisdictions throughout the species ranges; therefore, local management actions need to be assessed with reference to actions elsewhere and hence require national coordination. These findings underscore the need for sound understanding of animal movement dynamics to support evidence-based, transboundary conservation and management policy, tailored to the unique movement ecologies of species.
