Samoa is home to abundant plant life including indigenous species and some foreign introduced plant species. A majority of the foreign plants were introduced to Samoa in the pre-independence era through arrival of the early missionaries, Germans and Japanese, for various purposes from medicinal use to construction. These plants can be found across all the four islands; Upolu, Savai’i, Manono and Apolima. As part of the EU-GIZ Adapting to Climate Change and Sustainable Energy (ACSE) programme, a component of the Energy Bill and Sustainable Bioenergy, Samoa project focuses on biomass resource assessments at the Samoa Trust Estates Corporation (STEC) Plantation at Mulifanua, Upolu. Through fieldwork for biomass resource assessments at the non-leased land areas within the STEC Mulifanua plantation, eight common plants were identified and further scientific analysis on each was conducted by the Scientific Research Organisation of Samoa (SROS). SROS laboratory tests took place over a period of 14 days using the Quality Management System implemented by SROS and which also meets the requirements of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) standards, ISO/IEC 17025 (2005). Thus, this publication provides a brief description of these plants as well as some data on moisture content and energy content under different conditions.

The energy sector is important to Samoa's economic, social, infrastructure and environmental composition. This plan has therefore been developed using extensive consultation with many groups. The purpose of the Energy Sector Plan is to provide a comprehensive plan for the energy sector to deliver outcomes consistent with the overarching Strategy for the Development of Samoa (SDS) 2012-2016, with due regard for cross-cutting issues including emphasising the importance of raising living standards, increasing resilience and boosting productivity for sustainable development. It provides a resourcing framework to support implementation of the plan.

ABSTRACT: Coastal fish populations are typically threatened by multiple human activities, including fishing pressure and run-off of terrestrial pollution. Linking multiple threats to their impacts on fish populations is challenging because the threats may influence a species directly, or indirectly, via its habitats and its interactions with other species. Here we examine spatial variation in abundance of coral reef fish across gradients of fishing pressure and turbidity in Fiji. We explicitly account for multiple pathways of influence to test the alternative hypotheses that (1) habitat moderates predation by providing shelter, so habitat loss only affects prey fish populations if there are abundant predators, (2) habitat change co-drives biomass of both prey and predator functional groups. We examined responses of 7 fish functional groups and found that habitat change co-drives both predator and prey responses to turbidity. Abundances of all functional groups were associated with changes in habitat cover; however, the responses of their habitats to turbidity were mixed. Planktivore and piscivore abundance were lower in areas of high turbidity, because cover of their preferred habitats was lower. Invertivore, browser and grazer abundance did not change strongly over the turbidity gradient, because different components of their habitats exhibited both increases and decreases with turbidity. The effects of turbidity on fish populations were minor in areas where fish populations were already depleted by fishing. These findings suggest that terrestrial run-off modifies the composition of reef fish communities indirectly by affecting the benthic habitats that reef fish use.

Coastal ecosystems can be degraded by poor water quality. Tracing the causes of poor water quality back to land-use change is necessary to target catchment management for coastal zone management. However, existing models for tracing the sources of pollution require extensive data-sets which are not available for many of the world’s coral reef regions that may have severe water quality issues. Here we develop a hierarchical Bayesian model that uses freely available satellite data to infer the connection between land-uses in catchments and water clarity in coastal oceans. We apply the model to estimate the influence of land-use change on water clarity in Fiji. We tested the model’s predictions against underwater surveys, finding that predictions of poor water quality are consistent with observations of high siltation and low coverage of sediment-sensitive coral genera. The model thus provides a means to link land-use change to declines in coastal water quality

Despite a growing body of literature on integrated land–sea management (ILSM), very little critical assessment has been conducted in order to evaluate ILSM in practice on island systems. Here we develop indicators for assessing 10 integrated island management principles and evaluate the performance of planning and implementation in four island ILSM projects from the tropical Pacific across different governance structures. We find that where customary governance is still strongly respected and enabled through national legislation, ILSM in practice can be very effective at restricting access and use according to fluctuations in resource availability. However, decision-making under customary governance systems may be vulnerable to mismanagement. Governmentled ILSM processes have the potential to design management actions that address the spatial scale of ecosystem processes and threats within the context of national policy and legislation, but may not fully capture broad stakeholder interests, and implementation may be poorly coordinated across highly dispersed island archipelagos. Private sector partnerships offer unique opportunities for resourcing island ILSM, although these are highly likely to be geared towards private sector interests that may change in the future and no longer align with community and/or national objectives. We identify consistent challenges that arise during island ILSM planning and implementation and offer recommendations for improvement.
