On 20 November 2006 the Biological Diversity Advisory Committee (BDAC), whose role it was to advise the then Australian Government Minister for the Environment and Heritage, held a one day workshop in Canberra on climate change and invasive species impacts on biodiversity. Eight talks were given, followed by a session of free discussion. Most attendees were experts from government departments, universities, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and cooperative research centres (CRCs).
Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.
Situated between Fiji to the west and Samoa to the northeast, the Kingdom of Tonga (referred
to as Tonga) is comprised of 171 scattered islands of which less than 50 are inhabited. The islands are
mainly composed of limestone formed from uplifted coral. Current critical environmental concerns have
arisen due to deforestation; damage to coral reefs and the introduction and spread of invasive alien
species. Anthropogenic pressure has resulted in extensive modification of all ecosystems on the
Natural disasters such as hurricanes, cyclones, and tropical depressions cause average annual direct losses of US$284 million in the Pacific. With a combined population of fewer than 10 million people, annual losses are the highest in the world on a per-capita basis. Extreme weather events such as heavy rainfall are closely linked to climate change, suggesting that Pacific Island nations face increasing risk of disasters such as flooding and landslides. Proactive management through infrastructure development, social solutions, and/or ecosystem-based adaptation can mitigate these risks.
This report examines the role of the ecosystem services in reducing the vulnerability of the people of the Pacific Islands to climate change. Specifically, it describes the decision-making frameworks and the current state of knowledge of specific ecosystem-service/development relationships that are relevant to EbA.
Since the early 1990s the Secretariat of the Pacific Regional Environment Programme (SPREP) has been promoting the use of environmental planning and assessment processes amongst its member countries and territories. SPREP's approach to environmental planning and assessment has been part of a global programme for improving environmental management and supporting sustainable development.
The biodiversity of the Pacific region is recognised as being globally significant. The Solomon Islands was recently included into the famous "Coral Triangle", the area of ocean considered to have the highest marine biodiversity in the world. This includes the waters of the Philippines, Indonesia and Papua New Guinea. The Solomon Islands Rainforest Ecoregion is recognised as "one of the world's great Centres of Plant Diversity"
On January 6, 2004, the full force of Cyclone Heta, a category 5 cyclone, hit the island of Niue. In addition to the loss of life and property, serious damage was done to the forests and
other ecosystems of the island, particularly on the north and west sides. If not blown over, most trees and other large vegetation were stripped of leaves and branches and subjected to
A Workshop on Regional Action to Combat Invasive Alien Species on Islands to Preserve Biodiversity and Adapt to Climate Change highlighted successes, deepened connections within regions and facilitated the exchange of experiences across regions.While discussions outlined significant obstacles to invasive alien species management2 on islands, they also showcased how targeted successes have led to major gains for conservation and development.Collaboration across developmental and environmental sectors and sustained support are critical to success in this field.Exciting new initiatives are dev
