This desktop study is focused on presenting known and available baseline data on alien and invasive species and key biodiversity of Pitcairn which will inform stakeholders during the development of the Territorial Invasive Species Strategy and Action Plan (TISSAP). It delivers annotated inventories of (i) invasive alien species by island, invasiveness and habitat including risk assessment ranking; (ii) key endemic and threatened species at island and site level; (iii) designated natural areas and ecosystems with notes on threat/pressures on these areas; (iv) An annotated inventory of at-risk invasive species in neighboring countries with pathways of introduction and dispersal and (v) invasive species prevention, management/control related projects undertaken on Pitcairn and on-going initiatives.

Humanity has altered the planet in many detrimental ways, from the warming of our climate to the ever-diminishing wildernesses on land and in the sea. But in such a complex system as the Earth, science must always keep searching – for both solutions to problems already identified and new threats coming our way. UNEP’s Frontiers Report does this by identifying and exploring areas of emerging or ongoing environmental concern. The 2022 edition delves into three issues: noise pollution in cities, the growing threat of wildfires and shifts in seasonal events – such as flowering, migration and hibernation, an area of study known as phenology.

Humanity is waging war on nature. This is senseless and suicidal. The consequences of our recklessness are already apparent in human suffering, towering economic losses and the accelerating erosion of life on Earth. This report represents a scientific blueprint for howclimate change, biodiversity loss and pollution can be tackled jointly within the framework of the Sustainable Development Goals. The report is a synthesis based on evidence from global environmental assessments.

The Cook Islands comprises 15 islands with a total land area of 237 sq km and a maximum height above sea-level of 652 m. The islands are scattered over an Exclusive Economic Zone (EEZ) of 1.8 million sq km; one of the largest EEZ’s in the South Pacific.

This proposal has been prepared by the Ocean and Islands Programme (OIP) within the Pacific Islands Applied Geoscience Commission (SOPAC) in collaboration with the National Institute of Water and Atmospheric Research (NIWA). It has been prepared in response to an invitation1 from the Secretariat of the Pacific Regional Environment Programme (SPREP) to assist the Cook Islands in deriving coastal related information to underpin and inform climate change adaptation decisions for coastal areas of Mangaia Island.

Flooding imposes significant costs on households and businesses located in the lower Vaisigano catchment area. SOPAC, under the European Development Fund (EDF) project Reducing Vulnerability of Pacific ACP States, has worked with the Government of Samoa to develop the Samoa Flood Management and Action Plan, which identifies actions for government agencies, the private sector, NGOs and communities responsible for flood and floodplain management that can assist in reducing flood risks in Samoa, particularly in the lower Vaisigano catchment area located in Apia, which is subject to frequent flooding.
