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. However, there are a paucity of data pertaining to the costs, effectiveness, and feasibility of most management options. In the wake of two major flood events and a cyclone occurring between January and December 2012, we conducted a state-of-the-science assessment of disaster risk reduction for flooding in the Ba and Penang River catchments in Viti Levu, Fiji to identify the most cost-effective management options for communities and households (Figure E1). The analysis accounted for the biophysical and socioeconomic impacts of flooding, the costs, benefits, and feasibility of management, and the potential impacts of climate change.

Invasive alien species (IAS) are animals, plants or other organisms that are introduced into places outside their natural range, negatively impacting native biodiveristy, ecosystem services or human well-being. IAS are one of the biggest causes of biodiversity loss and species extinctions and are also a global threat to food security and livelihoods. IAS are compounded by climate change. Climate change facilitates the spread and establishement of many alien species and creates new opportunities for them to become invasive. IAS can reduce the resilience of natural habitats, agricultural systems and urban areas to climate change. Conversely, climate change reduces the resilience of habitats to biological invasions. It is essential that IAS be incorporated in to climate change policies. This includes biosecurity measures to prevent the introduction of IAS to new regions as a result of climate change, and rapid response measures to monitor and eradicate alien species that may become invasive due to climate change.

Island conservation programs have been spectacularly successful over the past five decades, yet they generally do not account for impacts of climate change. Here, we argue that the full spectrum of climate change, especially Island conservation programs have been spectacularly successful over the past five decades, yet they generally do not account for impacts of climate change. Here, we argue that the full spectrum of climate change, especially sea-level rise and loss of suitable climatic conditions, should be rapidly integrated into island biodiversity research and management. Sea-level rise and loss of suitable climatic conditions, should be rapidly integrated into island biodiversity research and management.

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. The primary objective of this work will inform broader recommendations on improving the integration of ecosystems, biodiversity and climate change adaptation under the Biodiversity, Ecosystems and Climate Change in the Pacific - Analysis and Needs Assessment Project(The Project) which is part of a collaboration between the Secretariat for the Pacific Regional Environment Programme (SPREP) and Conservation International and was undertaken from January to July 2011. This report should be considered as a companion volume to the other 3 background reports produced under the Project: Climate Change Adaptation Options for Species and Ecosystems in the Pacific: Background Paper #1; Need Analysis for Information on Ecosystem, Biodiversity and Climate Change Adaptation in the Pacific Islands Countries and Territories; Background Paper #3; Report on the Results Workshop from Nadi, 12-13 May 2011; Background Paper #4. The findings of each of these reports will be synthesized into a single, shorter volume that targets decision-makers in planning, agriculture, environment, fisheries and disaster management institutions in the Pacific. However, the audience for this EbA report (Background Paper #2) is technical staff in these institutions as it explores the next level of detail on EbA potential and practicalities of implementation.
Direct and indirect effects of rats: does rat eradication restore ecosystem functioning of New Zealand seabird islands?

Introduced rats (Rattus spp.) can affect island vegetation structure and ecosystem functioning, both directly and indirectly (through the reduction of seabird populations). The extent to which structure and function of islands where rats have been eradicated will converge on uninvaded islands remains unclear. We compared three groups of islands in New Zealand: islands never invaded by rats, islands with rats, and islands on which rats have been controlled. Differences between island groups in soil and leaf chemistry and leaf production were largely explained by burrow densities. Community structure of woody seedlings differed by rat history and burrow density. Plots on islands with high seabird densities had themost non-native plant species. Sincemost impacts of rats were mediated through seabird density, the removal of rats without seabird recolonization is unlikely to result in a reversal of these processes. Even if seabirds return, a novel plant community may emerge.

The Helping Islands Adapt workshop was held in Auckland, New Zealand between the 11th and 16th of April 2010 to support regional action against invasive species on islands, in order to preserve biodiversity and adapt to climate change. It arose from decisions under the Convention on Biological Diversity (CBD) relating to invasive alien species and island biodiversity, and was hosted by the Government of New Zealand with support from a number of partner organisations and countries. The workshop focused on four major island regions: the Caribbean, Coral Triangle, Indian Ocean and Pacific, and involved participation by 82 people from 24 countries and territories, and 29 national, regional and international organisations (see participants list in Appendix 5). The workshop was specifically designed to allow for the maximum exchange of experience and support between representatives from diverse island regions working in invasive species management. It also included a field inspection of one of the Department of Conservation‘s invasive species management projects on Rangitoto Island in Auckland‘s Hauraki Gulf. The workshop built on efforts under the Cooperative Islands Initiative, a partnership launched at the World Summit for Sustainable Development and the CBD 6th Conference of the Parties in 2002. Its intended outputs had been agreed by the organiser‘s steering committee and set out as a 'road map‘ that was used to ensure clarity of the workshop‘s intended purpose, outputs and outcomes. An overview of the workshop, its sponsors, participants and conclusions was developed during the workshop and submitted to the 14th ?Subsidiary Body on Scientific Technical and Technological Advice (SBSSTA 14) to the Convention on Biological Diversity (CBD) in Nairobi 10-21 May 2010. That report is provided in full in Appendix 5 to these proceedings.

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). The various sections in this report are based upon topics discussed on the day, but they incorporate many additional findings drawn from recent research. Two previous climate change workshops have been held by BDAC and reports produced (Howden et al. 2002; Hilbert et al. 2007). Tim Low was commissioned to produce this report.

Predators play a critical role in ecosystems; however, when overly abundant, they can disrupt natural processes and cause extinctions of species. In particular, oceanic islands have endured many impacts of introduced mammalian predators. Whereas knowledge and management of introduced mammalian predators on islands is well advanced in natural landscapes, in inhabited landscapes, spanning rural and urban environments, comparatively less is known. We summarise key issues from the natural and social sciences in the management of introduced mammalian predators in inhabited landscapes of Aotearoa–New Zealand. We describe the shift in focus over the past few decades from management of introduced mammalian herbivores to predators in rural environments, and the growth in management of introduced mammalian predators in urban environments, both seeking to emulate conservation gains made in forested landscapes. We discuss the circumstances around companion animal management at the interface of the natural and social sciences. We summarise surveys of attitudes towards introduced mammalian predators, the role of biodiversity comanagement between Ma¯ori and Pakeha, and the importance of also considering non-biodiversity benefits from introduced predator management. We describe the rise of community predator control and large landscape projects aspiring for a ‘Predator Free New Zealand’, and how such an aspiration must be concurrent with habitat restoration. We make recommendations for further research on the basic population biology of predators in inhabited landscapes, and more long-term studies. Such studies should be integrated with examination of the motivations for predator management, as well as the biodiversity and social outcomes of such management. We conclude by remarking that introduced predator management is only one component of a robust national strategy for conservation of native biodiversity in New Zealand.

New Zealand, an archipelago of more than 2000 islands, has a terrestrial fauna especially depauperate in native land mammals. Kiore (Rattus exulans) was the first of four rodent species introduced by people. A project to eradicate invasive rats from Kapiti Island in 1996, represented a turning point in the technology, complexity and scale at which managers of natural heritage on New Zealand islands could operate. This paper includes case studies of some significant projects targeting rodents, sometimes with other introduced mammals, undertaken in the 12 years following Kapiti. Details of the methods, costs, results and outcomes are provided for Kapiti, Whenua Hou, Tuhua, Campbell, Raoul, Hauturu, Taukihepa, and Pomona islands, collectively representing a total of over 23,000 ha of habitat cleared of introduced mammals. Research and trials undertaken in the Kapiti project provided the basis for future environmental risk assessments, allowing other projects to focus on knowledge gaps. New trends in invasive species eradication in New Zealand include more challenging multi-species eradication projects, some of which are undertaken by self- funded community groups. To summarise the lessons of the New Zealand experience: a programmatic approach is recommended which will fit each eradication within a context or framework of goals for those islands; address biosecurity issues at the outset; build capability to attempt the most challenging and rewarding projects; facilitate investment in monitoring and manage expectations of stakeholders to ensure their ongoing support. Success breeds success but is never guaranteed.

Eradication of introduced species from inhabited islands requires consideration of both technical and social feasibility. Historically, biologists have struggled to engage successfully in the social components of eradication planning. Island communities have unique features that require consideration in eradication planning. Social impact assessment is a powerful planning tool used widely outside of wildlife management. We outline the core components of a social impact assessment as it could be applied to eradication planning on inhabited islands. We summarise previous experience in social impact assessment and community engagement for introduced predator eradication on inhabited islands, and as an example develop a social profile for inhabited islands of the Hauraki Gulf of New Zealand. We conclude that social impact assessment has great potential to improve eradication feasibility assessment, and should be applied routinely in eradication scoping on inhabited islands.
