Macroeconomic impact of natural disasters on a small island economy : evidence from a CGE model

Natural disasters are common in the Pacific Island countries. Fiji has been affected by many of these disasters. The most recent cyclone exerted substantial damage to infrastructure, agricultural and industrial activity in Fiji. The aim of this article is to incorporate these damages into Fiji's computable general equilibrium model and examine the short-run macroeconomic impact. Among the key results, it is found that cyclones negatively impact private income, consumption, savings, real GDP and real national welfare.

Are exports and imports cointegrated? Evidence from two Pacific Island countries

The aim of this paper is to investigate whether there is long-run relationship between exports and imports for two Pacific Island Countries -- Fiji and Papua New Guinea (PNG). This is an important issue because long-run convergence will ensure that trade imbalances are sustainable. We explore this issue using the bounds-testing approach to cointegration and find that while exports and imports for Fiji and PNG are indeed cointegrated, the coefficient on exports is unity only in the case of Fiji. These results imply that Fiji satisfies the strong form of its intertemporal budget constraint while PNG satisfies only the weak form of its intertemporal budget constraint.

Tourism and economic growth: a panel data analysis for Pacific Island countries

The contribution of tourism to the economic growth of Pacific Island countries (PICs) has achieved significance in the past decade. The shift in the economic policies of the PICs from the late 1980s has been decisively away from import substitution and agriculture to urban-based manufacturing and services sectors. Tourism is the main component of the services sector in the PICs. The contribution of tourism to economic growth in Fiji, Tonga, the Solomon Islands and Papua New Guinea is expected to grow. The authors use panel data for the four PICs to test the long-run relationship between real GDP and real tourism exports. They find support for panel cointegration and the results suggest that a 1% increase in tourism exports increases GDP by 0.72% in the long run and by 0.24% in the short run.

Conservation of the endemic dwarf carnivores of Cozumel Island, Mexico.

Cozumel Island, Mexico, harbours two endemic species of dwarf procyonids: the Pygmy Raccoon Procyon pygmaeus and the Dwarf Coati Nasua nelsoni. Both species are Critically Endangered, and are among the world’s most threatened Carnivora. Here we summarise the research we have been conducting on their ecology, evolution, genetics, and conservation. We also summarise the conservation initiatives we have been undertaking and promoting in order to advance the conservation of these unique species and their habitats. This effort illustrates the importance of an interdisciplinary approach in conservation science and action in maximising effectiveness. Nevertheless, the precarious status of the species make it imperative to continue and expand the work we have carried out in Cozumel to prevent two imminent global extinctions.

Comparative ecology of island and mainland swamp antechinus populations

The demography, reproduction and behaviour of the swamp antechinus, a small carnivorous marsupial, were compared in island and mainland populations. Divergent demography and behaviour occurred between populations, with island animals benefiting from increased productivity caused by nesting seabirds. However, evolutionary divergence in life-history and morphology, which occur in island rodent populations, were not recorded.

Australia and Japan in the South Pacific island countries : a general appraisal through the concepts of structural power

This study examines several specific fields of activity of Australia and Japan in the areas of security, production, finance, development assistance, information, education and regional organization. Using the concept of structural power, it observes the sources of Australian and Japanese strenght in the region, the growing imbalance in the bilateral Australia-Japan relationship, and also the coexistence of affinities and differences in the development opportunities opened to the South Pacific Island Countries.

Bathymetry and frontal system interactions influence seasonal foraging movements of lactating subantarctic fur seals from Marion Island

Sixteen lactating subantarctic fur seals Arctocephalus tropicalis were satellite-tracked during the winter of 2006 (n = 6), summer of 2006/07 (n = 6) and autumn/winter (n = 4) of 2007, from Marion Island, Southern Ocean. Despite varied individual movement patterns, a favoured foraging area lay to the northeast of the island. In contrast to findings for populations at similar latitudes, seals from Marion Island did not undertake short overnight foraging trips, but trips consistently went beyond 300 km from the island. This aligns with the at-sea duration of lactating seals’ foraging trips from temperate Amsterdam Island, but differs from subantarctic Crozet and Macquarie islands. Time spent at sea, maximum distances travelled and movement variation of tracks from the island varied seasonally. Faecal analysis suggests the diet comprised primarily myctophid fish with limited seasonal variation. Well-defined areas of restricted movement coincided with significant bathymetric features to the west/northwest of the Crozet Plateau, with the Del Caño Rise clearly being important. Positive and negative sea-surface height anomalies (compared to the mean) appeared to be preferred by most seals across seasons. Higher summer sea-surface temperatures correlated with the movements of some seals. Higher chlorophyll a concentrations dictated transit and foraging areas during summer. Bathymetrically influenced oceanographic variables likely explain these preferred long-distance eastward movements. The Îles Crozet and Marion island subantarctic fur seals differ in their foraging ecology despite being neighbours. Conversely, the subantarctic fur seal populations from the distant Amsterdam and Marion islands appear to be similarly influenced by such environmental factors.

Comparison of life-history characteristics of island and mainland populations of the swamp antechinus

The reproductive ecology of the swamp antechinus Antechinus minimus, a small dasyurid (Dasyuridae) marsupial with obligate male semelparity, was investigated in populations inhabiting the mainland coast and on a nearby offshore island in south-eastern Australia. The size and sex ratios of litters, individual body mass and size, timing of births and female longevity were determined from live-trapped animals. The island population had significantly smaller litter sizes and greater adult body mass in comparison with the mainland population. This is consistent with features of the ‘island syndrome’, which predicts directional selection for these traits in high-density populations with reduced extrinsic mortality. However, inter-annual variability in litter sizes in the island population suggests that litter size is more responsive to fluctuating local conditions, such as population density, which is likely to affect food availability, rather than directional genetic changes. In contrast with other antechinus species, biased sex ratios were not evident. In addition, large variations of the timing of births were estimated at both sites and these appear to be related to seasonal conditions such as autumn rainfall and female body mass before mating.

Aid and growth in small island developing states

Aid flows to small island developing states (SIDS) are enormous by international standards when compared to the size of their economies. Yet these countries face many severe economic challenges and many have experienced declines in the living standards of their citizens. This paper looks at the impact of aid on what is treated as a necessary precondition for improvements in living standards, typically defined. Specifically, it examines the impact of foreign aid on real per capita income growth in SIDS by econometrically analysing cross-country data for the period 1980 to 2004. A variety of econometric techniques and measures of aid are used. Results suggest that foreign aid is effective at spurring economic growth but with diminishing returns.

Vulnerability, trade, financial flows and state failure in small island developing states

Small Island Developing States (SIDS) are very different to other developing countries. Relative to GDP they have the highest levels of foreign trade and aid receipts of all developing countries. Remittances from abroad are a far more important source of income for SIDS, and some depend very heavily on export revenues. The quality of governance varies tremendously among SIDS, they are over-represented among countries classified as fragile states and many are prone to state failure. These and other factors combine to make SIDS highly vulnerable to external economic shocks. Achieving development in SIDS is as a consequence an especially complex task that requires an understanding of the roles played by aid, trade, remittances and governance in these countries. This paper looks at these issues, along with providing various stylised facts about SIDS. In so doing it serves as a background and broad contextual setting for the papers that follow in this Special Issue on 'Fragility and Development in Small Island Developing States'.

Inbreeding and testicular abnormalities in a bottlenecked population of koalas (Phascolarctos cinereus)

Habitat destruction and fragmentation, interactions with introduced species or the relocation of animals to form new populations for conservation purposes may result in a multiplication of population bottlenecks. Examples are the translocations of koalas to French Island and its derivative Kangaroo Island population, with both populations established as insurance policies against koala extinction. In terms of population size, these conservation programs were success stories. However, the genetic story could be different. We conducted a genetic investigation of French and Kangaroo Island koalas by using 15 microsatellite markers, 11 of which are described here for the first time. The results confirm very low genetic diversity. French Island koalas have 3.8 alleles per locus and Kangaroo Island koalas 2.4. The present study found a 19% incidence of testicular abnormality in kangaroo Island animals. Internal relatedness, an individual inbreeding coefficient, was not significantly different in koalas with testicular abnormalities from that in other males, suggesting the condition is not related to recent inbreeding. It could instead result from an unfortunate selection of founder individuals carrying alleles for testicular abnormalities, followed by a subsequent increase in these alleles’ frequencies through genetic drift and small population-related inefficiency of selection. Given the low diversity and possible high prevalence of deleterious alleles, the genetic viability of the population remains uncertain, despite its exponential growth so far. This stands as a warning to other introductions for conservation reasons.
