Increased interest in indigenous ecological knowledge (IEK) has led to concern that it is vulnerable amidst social and ecological change. In response, multiple authors have recommended the establishment of programs for the maintenance and revitalization of IEK systems. However, few studies have analyzed the methods, opportunities, and challenges of these programs. This is a critical gap, as IEK maintenance is challenging and will require layered and evidence-based solutions. We seek to build a foundation for future approaches to IEK maintenance. First, we present a systematic literature review of IEK maintenance programs (n = 39) and discuss the opportunities and challenges inherent in five broad groups of published approaches. Second, we use two case...

Sunken wood from the Vanuatu Islands: identification of wood substrates and preliminary description of associated fauna
Provedor de dados: 5
Autores: Pailleret, Marie; Haga, Takuma; Petit, Patricia; Prive-gill, Catherine; Saedlou, Nima; Gaill, Francoise; Zbinden, Magali.
Two trawl samples of natural sunken wood collected near Vanuatu were identified based on histological studies. Detailed descriptions were made and microphotographs of the cell types were taken, using the three classical sections (cross, tangential and radial). The botanical characters were compared first to the native flora of Vanuatu, then also to the introduced species. The possibility of transportation by ocean currents with a mainly southern and eastern direction is discussed. The first sample lacks apparent colonization marks. Its main histologic character is the presence of `paedomorphic type I rays' which relates it to the shrubby genera Fitchia (Asteraceae) and Fuchsia (Onagraceae): both are known in Polynesia but they seem not to be recorded from...

Temporal magma source changes at Gaua volcano, Vanuatu island arc
Provedor de dados: 5
Autores: Beaumais, Aurelien; Bertrand, Herve; Chazot, Gilles; Dosso, Laure; Robin, Claude.
Gaua Island (also called Santa Maria), from the central part of the Vanuatu arc, consists of a large volcano marked by a caldera that hosts the active Mount Garet summit cone. In this paper, a geochemical study including Sr, Nd, Pb and Hf isotopic compositions of 25 lavas emitted since 1.8 Ma is presented, with a focus on the volcanic products that preceded (old volcanics, main cone and pyroclastic series) and followed (Mount Garet) the caldera forming event.  All lavas show an island arc signature with enrichment in LILE and depletion in HFSE. Post-caldera lavas define a medium-K calc-alkaline trend, whereas lavas from the former main cone have high-K calc-alkaline compositions. Compared to the pre-caldera volcanic suite, the Mount Garet lavas have...

Temporal source evolution and crustal contamination at Lopevi Volcano, Vanuatu Island Arc
Provedor de dados: 5
Autores: Beaumais, Aurelien; Chazot, Gilles; Dosso, Laure; Bertrand, Herve.
Here we present a new geochemical study of Lopevi volcano, one the most active volcanoes in the Vanuatu island arc. We focus on the temporally well-defined sequence of lava flows emitted since 1960, and for the first time, on pre-1960 volcanic products, including high-MgO basalts and felsic andesites, the most evolved lavas sampled so far on this island. This work reports the first Pb and Hf isotopic study of lavas from Lopevi island. These lavas display correlations between differentiation indexes such as SiO2 content and isotopic ratios. The felsic andesites extend the known correlations with both the least (Sr-Pb) and the most (Nd-Hf) radiogenic isotopic compositions on the island. Our results confirm that the rising magma interacted with the sub-arc...

The genus Syzygium (Myrtaceae) in Vanuatu
Provedor de dados: 16
Autores: Tuiwawa, S.H.; Craven, L.A.; Sam, C.; Crisp, M.D.
Twenty species of Syzygium occur in Vanuatu of which eighteen are indigenous (six being endemic and one being an ancient introduction) and two are recently introduced. Three species are newly described: S. chanelii, S. flabellum and S. vanuatuense. The Syzygium flora of Vanuatu has strong links at species level to that of the Solomon Islands and Fiji, less strong links to elsewhere in the southwest Pacific and apparently no links to New Caledonia. Descriptions are provided for each species occurring in Vanuatu and identification keys are provided for flowering and vegetative material.

Export Performance in South Pacific Countries Comparatively Well Endowed with Natural Resources: Solomon Islands and Vanuatu, 1960 to 1999
Provedor de dados: 31
Autores: Fleming,   Euan M.; Blowes,   Anita.
Stochastic dominance analysis was used to assess export performance in two Melanesian countries of similar size and structure that are comparatively well endowed with natural resources: Solomon Islands and Vanuatu. Total export values increased over the study period in Solomon Islands, brought about by a significant increase in the value of non-agricultural resource exports. Agricultural exports showed small increases but the average annual rate of growth was only 1.3 per cent for agricultural export values compared with 10.7 per cent in non-agricultural export values.  The record of commodity export performance in Vanuatu over the study period was less impressive, with a small average annual decline in total export values. This decline was caused by...

The Development of Vanuatu: An Analysis of Trends, Issues and Policies
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Vanuatu is one of the five least developed Pacific island nations according to the classification of the United Nations. This article reviews the situation of Vanuatu in relation to its development generally but paying particular attention to: • Public and private finance; • Social issues such as education and health; • Its trade and external balance; and  • Economic infrastructure. Policy suggestions are made in relation to each of these matters and an assessment given of the development status of Vanuatu.
