This report describes, quantifies and, where possible, calculates the economic value of Tonga's marine and coastal resources. Seven key marine ecosystem services are evaluated in detail: subsistence and commercial fishing; minerals and aggregate mining; tourism; coastal protection; carbon sequestration; and research, management and education. Others services are explored as well, including cultural and traditional values associated with the sea, potential future industries and other human benefits that have not yet been analysed or exploited. The scarcity of data about many of these ecosystem services prevents alculation of the total economic value, so the values below should be regarded as minimum estimates. Data gaps are described in detail in this report.

Solomon Islands is composed of almost 1000 islands and has the second longest coastline and the second largest Exclusive Economic Zone (EZZ) in the Pacific. These physical characteristics and the unique society and culture of the population are the basis of the fundamental relationship that Solomon Islanders have with the ocean and its ecosystem services. This analysis aims to assist decision-makers to recognise the role that marine ecosystems play in human wellbeing. Ecosystem services, described as the benefits that humans receive from ecosystems, are often not fully considered in decisions, because the market fails to reveal their true value. Failure to consider the role that marine ecosystems play in supporting livelihoods, economic activity and human wellbeing has, in many instances, led to inequitable and unsustainable marine resource management decisions.

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.
