Biodiversity is a term that describes the number and diversity of the different plants, animals, and other living things within our environment. Biodiversity is a key factor in natural resilience to the impacts of environmental change. All species contribute to environmental resilience, including those that are naturally common and those that are rare. Natural biological communities have evolved over thousands or millions of years and have resulted in adaptations to local conditions that make these species resilient to natural environmental change. This community of native species contributes to ecosystem functioning and together provides the ecosystem services that we rely on. These services include provisioning (such as food, fuel, raw materials, and medicines), regulating (such as provision of clean water and air, climate regulation and flood protection, waste decomposition, and biological pest and disease control), supporting (such as nutrient cycling), and cultural services (such as spiritual and heritage value, recreation, and science). When ecosystems are disturbed or disrupted, due to habitat modification, overharvesting, or invasive species, their function is affected, the benefits they offer decline, and resilience to further change is reduced. In this time of unprecedented global environmental change, protecting biodiversity is more important than ever to ensure we can retain the benefits of the natural world on which all our lives depend.

There has been a continuous global concern regarding the disastrous impacts of climate change, sea level rise and climate related hazards. Scientific findings revealed that the global climate system is being adversely affected due to the accumulation of Greenhouse Gases (GHG) in the atmosphere. This has been scientifically proved to be caused by anthropogenic activities.

This NDC review process was designed to provide a formal framework within which governments would increase the ambition of their actions against climate change and reduce its GHG emission over time, with the intention that each successive NDC would represent a progression beyond a country’s current NDC and ultimately allow to meet the aims of the Paris Agreement goal .

The freshwater resources of the Pacific Islands are diverse, from islands where large rivers abound to countries where no surface water resources exist and whose people rely solely on rainwater for their potable and economic needs.

The little re ant, Wasmannia auropunctata, is a small ant native to Central and South America, which has been introduced into a third of the Paci c region's island groups. It is considered by invasive experts to be the greatest ant species threat within the Paci c islands region.

A priority for Small Island Developing States (SIDS) is effective planning and financing of actions to address the impacts of climate change. This paper examines the vital role that regional institutions play in sharing SIDS relevant approaches and knowledge, and in delivering specialist skills and knowledge to support national efforts. It goes on to highlight the work of the Climate Resilient Islands Partnership, which links the Caribbean, Indian Ocean and Pacific Regions, and is working to rapidly scale-up cost-effective services to SIDS through inter-regional cooperation and exchange.
Eradication of invasive animals and other island restoration practices in Seychelles: achievements, challenges and scaling up perspectives
Island and Ocean Ecosystems, BRB

Rocamora, G.

2019
In recent decades Seychelles has accumulated extensive experience in the management of invasive species and other island restoration practices. Non-government organisations (NGOs), governmental, parastatal and private stakeholders have conducted successful programmes to control and eradicate invasive animals and plants, particularly on small islands of high biodiversity value. Biosecurity protocols have been implemented to prevent (re)infestations. With at least 50 vertebrate populations (33 mammal, 16 bird and one reptile) from 14 different species successfully eradicated, Seychelles is the third country in the world after Australia and the USA for invasive vertebrate eradications from tropical islands, and the seventh when considering all countries. Twenty-four islands have bene?ted from invasive vertebrate eradications and other ecosystem restoration processes to create refuges for native biodiversity. About 470 ha of woodland have been rehabilitated through replanting and recovery of native vegetation, and at least 36 successful island translocations of native birds and reptiles have been conducted. This includes 16 conservation introductions or reintroductions of six endemic land birds (all but one threatened), two of a terrapin species and 18 of Aldabra giant tortoises. Recovery of native species and natural recolonisations have occurred on islands where invasive predators have been removed. As a result, four globally threatened endemic land birds have been down-listed in the IUCN Red List and dozens of other native species including seabirds, land birds, reptiles, invertebrates and plants have also bene?ted. Future challenges include increasing the proportion of the country’s land area free of rats and cats from 3.9% to potentially 15.4%, mainly in the outer islands, and 50% in the long term if Aldabra and Cosmoledo are considered. Factors limiting future eradications and translocations are discussed. Alternative conservation approaches such as ‘mainland-islands’ are recommended for large islands, and the development of partnerships with nature-based tourism is encouraged to help fund further restoration.
