Tuna purse seining in the Pacific Islands region is the world’s largest tuna fishery. Currently some organizations are publicising the desirability of replacing at least some of the purse seining with pole-and-line fishing—a technique which requires significant quantities of live baitfish. This research was undertaken to determine the quantity of baitfish required to replace purse seining. It is estimated that to catch a million tonnes of tuna annually in the Pacific Islands region (i.e. replace the purse seine fishery) would require about 31,250 t of baitfish per year. Historical catches of baitfish suggest that catches this large may not be possible. There is also some question of the practicality and desirability of a substantial increase in baitfish harvesting in the region. 相似文献

Transition to low carbon sea transport is a logical response to the extreme dependency of the Pacific Islands region on imported fossil fuel, its significant vulnerability to the effects of climate change and the critical shipping needs of Pacific Island countries (PICs). Building on previous work in low carbon sea transport in the Pacific, this paper further considers the barriers to achieving such transition by assessing, through a ‘post-Paris Agreement’ lens, the Intended Nationally Determined Contributions (INDCs) submitted by PICs and contrasting these to the near total lack of investment and planning for low carbon transition in the transport sector with the parallel occurrence in the electricity sector where ~USD 2 billion of donor investment is deployed or queued despite electricity using only ~20% of fossil fuel across the region. Consistent with recent international studies, inadequate and inappropriate financing and policy have been identified as dominant transition barriers for low carbon sea transport development in PICs. This paper further examines the regional level barriers to policy development, and finds them inhibited by the silo nature of the major regional actors. The implications that the Paris Agreement has for climate financing to support the essential research and capacity development needed to underpin a successful low carbon sea transport transition strategy at any useful scale and speed are also considered in this paper. 相似文献

The Kermadec Islands Marine Reserve (KIMR), which is located at 30°S, is New Zealand's largest marine reserve at 748 000 ha, and its biota is composed of a mix of warm temperate, subtropical, and tropical species. A depth‐stratified ecological survey was conducted of the abundance and percentage cover of macrobenthic species and of the water column at two sites (Meyer Island and West Chanter Island), 2km apart. Significant differences in benthic community structure and in water column turbidity and chlorophyll concentrations were observed between the two sites despite their proximity and physical similarity. Compared with other “snapshot” surveys of benthic community structure at sites within the KIMR there was a high degree of similarity among the species observed, but often a low degree of similarity in species abundance or percentage cover as a function of depth. We suggest that despite its isolation and the degree of difficulty of working at this location, a full‐scale ecological survey of the coastal marine biota of the KIMR is warranted to better understand New Zealand's subtropical marine biota and its affinities with other marine biotas of the South Pacific. 相似文献

Project monitoring is now a standard requirement in natural resource management programs, bringing opportunities for greater accountability, adaptive management and social learning. While considerable effort has gone into designing appropriate monitoring frameworks and indicators for marine and coastal management, there has been less sharing of the mechanics of approaches that maximise collaboration and learning by multiple stakeholders. This paper outlines the project monitoring approach developed in the Pacific Islands International Waters Project (IWP), a project funded by the Global Environment Facility (GEF) involving 14 Pacific Island Countries. We find that a monitoring approach based on indicators to assess supportive processes, behavioural change and human–environmental conditions is useful for monitoring the long- and short-term impacts associated with integrated coastal management programs. Giving project staff the lead in indicator development has supported more strategic project planning and improved the relevance and value of the indicators developed. However, successful implementation of monitoring programs calls for ongoing collaboration, technical support and capacity building amongst key stakeholders. 相似文献

The framework for management of the ocean and coasts of the Pacific Islands region has been evolving since the early 1970s when Pacific Island countries played a significant role in the negotiations leading to the 1982 United Nations Convention on the Law of the Sea. Commencing with a summary of the provisions of relevant international instruments, this paper presents a broad overview of regional arrangements for ocean and coastal management in the Pacific Islands region. It considers the work of the various regional intergovernmental organizations with active programmes in ocean research and governance and the consultative arrangements that support coordination and collaboration. Consultative arrangements involving other stakeholders, such as local, regional and international nongovernmental organizations are summarised. To improve environmental governance and address increasing environmental threats, particularly in relation to coastal area management, consultative arrangements need strengthening. This applies equally to national and regional level consultation. The institutional and policy framework for the management and conservation of oceanic fish stocks that Pacific Island countries have been refining over a period of 25 years is suggested as providing useful lessons for strengthening coastal management processes and strategies in the region. 相似文献

Two species of spiny lobsters (marine crayfish) inhabit New Zealand waters: Jasus edwardsii (Hutton, 1875), and J verreauxi (H. Milne Edwards, 1851). J edwardsii, the more common species, is present along most rocky coastlines in New Zealand, but is more abundant in the south‐west of the South Island and at the Chatham Islands. The species apparently reaches its northern limit of distribution at the Three Kings Islands (34°S) and its southern limit at the Auckland Islands (51°S). J. verreauxi, the less common species, is almost solely restricted in New Zealand waters to the north‐east coast of the North Island. It is uncommon in the west and the south of the North Island, and is rare in the South Island. J. verreauxi apparently reaches its northern limit of distribution at the Kermadec Islands (31°S), and its southern limit near Bluff (47°S) in the South Island. 相似文献

Non-Governmental Organizations (NGOs) are playing important roles in environmental conservation and management. Some are actively involved in the development and implementation of marine spatial planning (MSP), especially in Europe where this has been embodied within a European Directive. MSP is being used by many countries to sustainably manage coastal and marine areas, and reduce conflicts. However, recommendations regarding specific NGO roles within the MSP process are lacking. Consequently, to fill this gap and discuss a way forward, a session at the 5th Global Conference on Oceans, Coasts and Islands (GOF5) brought together MSP experts and NGO representatives. This paper reports the conclusions of these discussions and presents a summary guideline document for efficient and effective NGO MSP engagement. 相似文献

鲍是重要的海珍品,羊鲍(Haliotisovina)是主要生活在热带岩岸潮间带大型经济鲍类底栖动物。为了研究南海岛礁羊鲍资源及其栖息环境,我们在宣德群岛的永兴岛和七连屿,永乐群岛的羚羊礁、甘泉岛和晋卿岛进行了羊鲍资源分布及其栖息水环境研究。按照《海岛调查技术规程》中潮间带岩岸大型底栖生物调查方法,对羊鲍进行取样调查。按照《海洋调查规范第4部分:海水化学要素调查》(GB T 12763.4-2007),对羊鲍栖息地水环境的总无机氮、活性磷酸盐、悬浮物和叶绿素a等海水化学要素进行分析。结果表明,羊鲍在永乐群岛和宣德群岛都有分布,这些岛礁按永兴岛、七连屿、羚羊礁、甘泉岛和晋卿岛的顺序,分布密度依次增加,个头大小依次增大,总体来说羊鲍资源量小,有的岛礁海区几乎绝迹,亟需开展生态增殖和资源养护研究工作。水质调查表明,除永兴岛站位的悬浮物指标因填海作业未达标外,各站位的水质指标均达一类水标准且具有一定稳定性。因此,尽管南海岛礁受人类活动的影响,但该海域仍适合羊鲍栖息,是羊鲍资源养护、底播生态增殖和生态养护的适宜场所,符合建立海洋保护区的国家水质标准和环境条件。 相似文献

This paper reports on progress in developing a regional research and education strategy for Pacific Island countries and communities wishing to transition to a low carbon sea transport future. Sea transport is an absolute necessity for most such communities. All current services are fossil fuel based and are becoming increasingly unaffordable and unsustainable. The countries in the Pacific region are the most dependent on imported fossil fuels in the world, importing more than 95% of needs. Such dependency is having a crippling effect on national budgets and major impacts on key productive sectors. The region's transport issues are unique; small and vulnerable economies scattered at the ends of some of the longest transportation routes in the world and arguably the most challenging to maintain per capita and per sea mile. Alternatives to current fossil fuel powered sea transport have been almost totally ignored in recent regional and national debates and the issue has been largely invisible within the policy and donor strategy space at all levels despite concerted efforts over more than two decades to transition Pacific countries' electricity sector fossil fuel use. The University of the South Pacific has been collaborating with a network of stakeholders and knowledge partners since 2012 to advance this agenda, building off previous doctoral research and the resultant Sustainable Sea Transport Talanoa 2012. Prasad et al. (2013) set out the basis for a catalytic research program following from the consensually agreed outputs of SSTT 2012 and this paper records the progress made since. 相似文献

The words taboo, conservation area, reserve, protected area, and marine protected area (MPA) are used to refer to the community-based closures of the Pacific islands. Diverse definition and interpretation have led to confusion and debate, particularly as the Pacific islands engage with international protected area policies and partners. This case study from the Republic of Vanuatu traces the introduction, evolution and contemporary implementation of protected area typology. Higher-level debates often center more on symbolism and post-colonial ideologies than on the operational specifics of closure regimes. Island communities, indifferent to ongoing national-level discussions, are continuously adapting closures to contemporary contexts, utilizing indigenous and non-indigenous terms to differentiate among them. Protected area policy in the Pacific islands could be improved by recognizing the diverse closure typology of the region and building on the discursive status quo that is emerging at the community level. Future policy will be enhanced if it embraces the inherent flexibility and heterogeneity of Pacific island custom and culture to manage natural resources. 相似文献
