Coastal ecosystems such as mangroves can reduce risk to people and infrastructure from wave damage and flooding. The continued provision of these coastal defence services by mangroves is dependent on their capacity to adapt to projected rates of sea level rise. This report exploresthe capacity of mangrove soil surfaces to increase in elevation in response to local rises in sea level.

n More than 60 percent of the world’s reefs are under immediate and direct threat from local sources—such as overfishing, destructive fishing, coastal development, watershed-based pollution, or marine-based pollution and damage (see map inside front cover). n Approximately 75 percent of the world’s coral reefs are rated as threatened when local threats are combined with thermal stress. This reflects the recent impacts of rising ocean temperatures, linked to the widespread weakening and mortality of corals due to mass coral bleaching (figure ES-1, column 6).

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.

The Pacific Islands Applied Geoscience Commission (SOPAC) is currently executing the project Reducing Vulnerability in Pacific ACP States with funding from the European Development Fund (EDF). The project has the objective to reduce Pacific ACP States' vulnerability to natural disasters affecting their coasts through the development of an integrated planning and management system which targets: hazard mitigation and risk assessment; alternative sources of aggregates for construction; and water resources and sanitation. Major activities undertaken through this project with participating countries are: -assessment of aggregate resource supplies to mitigate the impact of unsustainable aggregate mining from the coastline; -development of bathymetric maps, 3D bathymetric and hydrodynamic models spatial databases relating to resource use, exploration and survey, and vulnerability to disasters; and -investigating and raising awareness about coastal processes.

The Government of Niue (GoN) is restructuring its Public Service which is a timely opportunity to integrate water management functions adopting the IWRM approach and principles in lieu of the current sectoral approach adopted over the last 3-4 decades. This will be an opportunity to integrate NGOs, civil society and all stakeholders in the process of water and wastewater management. The strengthening of the national capacity will enhance efficiency to deliver the required services by the public institutions, but also the awareness of the community on the sustainable use of water as a finite natural resource.

These goals are a big challenge to small Pacific Islands Countries with their small land masses, remote locations and small but rapidly growing populations making them vulnerable. Vanuatu shares these and other challenges to sustainable development. In Vanuatu real GDP per capita is still lower than in the 1980s, infrastructure is poorly developed, the population is rapidly growing at 2.6% per year, water resources are declining and in many places contaminated, and household water supplies are inadequate or absent. The country's capital and human resources are stretched and a better forward is needed.

The economic and social wellbeing of Pacific Island Countries are dependent upon the quality and quantity of their freshwater. Constrained by their relative small size, natural vulnerability, and limited human and financial resource base, Pacific Small Island Developing States face specific challenges to effectively manage their water resources.
