Project Snapshot - Vanuatu

SPREP Publications, Waste Management and Pollution Control

Available Online

Waste received at the main Bouffa landfill in Vanuatu is comprised of up to 35% beverage containers products (aluminium, PET, glass). Beverage containers are also commonly seen as litter and in informal stockpiles or burnt by communities in pits. Vanuatu has had limited success implementing long-term solutions for recovery of recyclable items, due to lack of financing, infrastructure, technical expertise, and formal waste collection services. The Vanuatu Department of Environmental Protection and Conservation (DEPC) views a Sustainable Financing system (known as a Product Stewardship Scheme (PSS)) as a solution to enable the collection and management of recyclable items. The DEPC, with the support of Donors and a Working Group of interested parties, has been developing the PSS since 2017. The DEPC seek for PacWastePlus to support the completion of additional components of this pathway – with the goal of implementing the PSS.

Project Snapshot - Tuvalu

SPREP Publications, Waste Management and Pollution Control

Available Online

Recognising Tuvalu has insufficient space to continually rely on waste disposal and stockpiling, the Tuvalu department of waste management (DWM) has recently implemented several initiatives to improve solid and hazardous waste management and reduce risks to their people and environment. Many of these initiatives have focused on the capital island, Funafuti - home to 50% of the population. The DWM now seeks to extend waste management initiatives to Tuvalu’s eight Outer Islands.

Project Snapshot - Niue

SPREP Publications, Waste Management and Pollution Control

Available Online

Items are imported into Niue in growing numbers, but there are currently limited viable options for their end-of-life management and/or export. As such most items imported are disposed of at the dumpsites or stockpiled on vacant land. Electronic waste stockpiles, in particular are increasing resulting in increased pollution and health risks to Niue people. The priority for Niue is to introduce a financially sustainable system to enable the long term collection, management and export of recyclable and end of life electronic items, utilising the new Recycle facility (funded by the Government of Australia)

Use natural enemies to manage widespread weeds in the Pacific

SPREP Publications, Island and Ocean Ecosystems, BRB

Available Online

We are a diverse bunch of people in the Pacific region, which spans about one third of the earth's surface and encompasses about half of the global sea surface. Natural enemies can be used to restore natural balance between weeds and the environment by introducing the enemies where they are needed.

Island invasives : scaling up to meet the challenge.

The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017. The papers demonstrate up-scaling in several aspects of eradication operations not least in ambition, land area, operational size, global reach and of course financial cost. In the space of a few decades, the size of islands treated for invasive species has increased by five orders of magnitude from a few hectares to over 100,000 ha or 1,000 km2. Meanwhile, the diversity of species being tackled has increased, as has the range of countries now actively carrying out island restoration work. Inspired by pioneers from New Zealand and Australia, principally, today the movement has spread to islands in all oceans and off all continents. This expansion has been informed by, and has in turn produced, growing experience in all aspects of this field, from non-target impacts to ecological responses to factors affecting eradication success. A major aim of publishing these Proceedings is to inform people who are, or will in the future be, planning new projects to free islands of invasive species. Regardless of its location or the target species involved, each successive operation builds on the experience of those who have gone before, and the papers in this volume represent an invaluable wealth of such experience.

Biological control of weeds in the Pacific Island countries and territories: current status and future prospects

Available Online

Day, Michael D.

Winston, Rachel L.

Biological control of introduced weeds in the 22 Pacific island countries and territories (PICTs) began in 1911, with the lantana seed-feeding fly introduced into Fiji and New Caledonia from Hawaii. To date, a total of 62 agents have been deliberately introduced into the PICTs to control 21 weed species in 17 countries. A further two agents have spread naturally into the region. The general impact of the 36 biocontrol agents now established in the PICTs ranges from none to complete control of their target weed(s). Fiji has been most active in weed biocontrol, releasing 30 agents against 11 weed species. Papua New Guinea, Guam, and the Federated States of Micronesia have also been very active in weed biocontrol. For some weeds such as Lantana camara, agents have been released widely, and can now be found in 15 of the 21 PICTs in which the weed occurs. However, agents for other commonly found weeds, such as Sida acuta, have been released in only a few countries in which the weed is present. There are many safe and effective biocontrol agents already in the Pacific that could be utilised more widely, and highly effective agents that have been released elsewhere in the world that could be introduced following some additional host specificity testing. This paper discusses the current status of biological control efforts against introduced weeds in the 22 PICTs and reviews options that could be considered by countries wishing to initiate weed biological control programmes.

Prioritisation of targets for biological control of weeds on Pacific Islands

Available Online

Quentin Paynter

Invasive weeds are one of the most serious threats to biodiversity and sustainable development in the Pacific region. Biocontrol is likely to be the only feasible way of managing many widespread weeds, but is not always appropriate or successful. With so many weed species to tackle and inevitably limited resources, prioritising where to direct control efforts most effectively is of key importance. Landcare Research recently developed a framework for the Australian government that allows the best and worst weed targets for biocontrol to be identified. Critical Ecosystem Partnership Fund and USDA Forest Service International Programs funding enabled this framework to be applied to weeds of the Pacific region.

The status of weed biological control in Vanuatu

Available Online

Bule, Sylverio

Day, Michael D.

Biological control of weeds in Vanuatu began in 1935, with the introduction of the tinged Teleonemia scrupulosa to control Lantana camara. To date, nine biological control agents have been intentionally introduced to control eight weed species. Seven of these agents have established on their respective hosts while an eighth, Zygogramma bicolorata, an agent for Parthenium hysterophorus has only recently been released and establishment is unlikely.

Biological control of Chromolaena odorata in Papua New Guinea (CP/1996/091)

Available Online

Day, Michael

The main outcome of the project was the control or significant reduction of chromolaena in most provinces of PNG. Areas that were once monostands of chromolaena have been converted back into subsistence farms, and plantations in which chromolaena was the main understorey species are now clear of the weed. This outcome was the result of the primary outputs of the project: (a) knowledge of the extent of the chromolaena problem and its impact of the livelihoods of smallholders, (b) an understanding of effective biocontrol agents and (c) significant capacity built in biocontrol of weeds.

Environmental Impact Assessment Application to introduce Puccinia xanthii for biological control of Xanthium pungens (cockleburr)

Paynter. Q.

The Cook Islands Ministry of Agriculture seeks approval for the release of the plan pathogen Puccinia xanthii Schw. (Pucciniales: Pucciniaceae) into Rarotonga for biological control (biocontrol) of the introduced plant cockleburr Xanthium pungens Wallr. (syn. Xanthium strumarium; Xanthium occidentale Bertol.) (Asterales: Asteraceae).
