United Nations to “Protect Fiji” — Environmental Awareness Key to Major Findings for Australia's State of the Marine Environment report
Biodiversity Conservation, Waste Management and Pollution Control, Anamua: Treasures of the Pacific Environment
Available Online
This United Nations-backed report, hosted by the Pacific Regional Environment Programme (SPREP) in collaboration with Australia’s environmental authorities, highlights critical insights from a comprehensive assessment of Fiji’s marine environment. Key findings include: Urgent need for environmental awareness: Enhanced public understanding is essential to safeguard Fiji’s rich marine resources from threats like marine pollution, coastal habitat destruction, and climate change impacts. Marine pollution pressure: Coastal waters are increasingly burdened by land-based pollutants—plastics, sewage, industrial runoff—and remnant debris from historical events (e.g., WWII wrecks), with contamination affecting marine ecosystems. Habitat degradation: Seagrasses, coral reefs, and mangrove ecosystems face degradation stemming from coastal development, deforestation, sedimentation, and unsustainable use. Climate change and invasive species: Rising sea levels and temperature increase stress marine ecosystems. Invasive species further destabilize native biodiversity and fish stocks. Policy and capacity gaps: Although Fiji is party to major environmental agreements, enforcement and systematic marine monitoring remain inadequate. Collaborative solutions: The report calls for strengthened coordination among UN agencies, SPREP, Fiji’s government, and Australian partners. Recommendations include expanding coastal climate-change observation, improving environmental education, enhancing marine pollution legislation, and bolstering community-based conservation efforts. Together, these insights emphasize that raising environmental awareness and fostering regional cooperation—especially with Australia—are vital to protecting Fiji's marine environment and achieving sustainable development goals.
Will Alien Plant Invaders Be advantaged Under Future Climates?

The last two decades have seen an upsurge in research into the potential synergies between invasive species and climate change, with evidence emerging of increased invader success under climate change. All stages along the naturalization-invasion continuum are likely to be affected, from the introduction and establishment of alien species to their spread and transition to serious invaders. A key question is whether alien plants will have a relative advantage under climate change conditions. So far, evidence for differential responses of alien invasive and native species to climate change drivers (elevated CO2) and outcomes (increasing temperature, changing rainfall patterns, changes in disturbance regimes) is mixed. Although alien invasive plants appear to be more responsive to elevated CO2 than many native species, plant response to elevated CO2 and other climate change components is dependent on environmental conditions and resource availability. Similarly, correlative modelling of species-climate relationships has not revealed clear evidence that invasive plants are likely to be able to increase the extent of suitable habitat under future climates any more than their native counterparts. We suggest that the most important driver of a shift to alien-dominated vegetation under climate change will be the superior capacity of alien invasive plants to take advantage of colonisation opportunities arising from climate change, such as extreme climatic events, changes in disturbance regimes, and widespread reduction in vegetation resilience as range margin populations decline. There are substantial challenges ahead for managing invasive plants under future climates. Weed risk assessment and management approaches must incorporate consideration of future climatic conditions. Most importantly, we will need a shift in management approaches away from a focus on the control of undesirable alien plant species to building resilience of resident vegetation assemblages, in association with targeted monitoring and early eradication of alien plant species.
