As early as 1990 the Intergovernmental Panel on Climate Change (IPCC) noted that the greatest single impact of climate change might be on human migrationwith millions of people displaced by shoreline erosion, coastal flooding and agricultural disruption.3 Since then, successive reports have argued that environmental degradation, and in particular climate change, is poised to become a major driver of population displacementa crisis in the making.
In most tropical countries, coral reef ecosystems provide coastal populations with a number of goods and services. However, a variety of anthropogenic practices threatens reef health and therefore jeopardizes the benefits flowing from these goods and services. These threats range from local pollution, sedimentation, destructive fishing practices and coral mining, to global issues such as coral bleaching.
The Convention on Biological Diversity (CBD) is one of the global conventions on environmental conservation that came out of the 1992 UN Conference on Environment and Development in Rio de Janeiro, Brazil. By signing and ratifying the CBD, countries have agreed to support its goals and aims. The three main objectives of the CBD are the conservation of biological diversity, the sustainable use of its components, and the fair
Satawal is a small flat coral island in the west central Caroline Islands about 1050 km east-south-east of Yap Island, at latitude 7'21' N, longitude 147'02' E. Although its surface is locally somewhat irregular, its greatest height is not more than about 4 meters above mean low water. Its long axis is about east-west and its area is 1.3 square km. It is surrounded by a fringing reef upward of 100 meters wide. It has no lagoon, so would be classified according to Tayama's scheme as a table reef. From the viewpoint of land ecology it is an atoll.
Fishing in Samoa is very important because one of the ways to achieve food security, particularly in
villages and rural areas. In many communities do not value taking care of the economy
and the marine environment. Making and using such fisheries jurisdiction for-or-not there

The monitoring and evaluation system of CRISP programme is semester based with 2 reports describing activities from the 1st of January to the 30th of June and the 1st of July to the 31st of December respectively. Actions occurring on the field are classified according to the type of activities, which are explained according to projects comprised into different compo-
The wetlands of 21 countries and territories of the Pacific Islands region are reviewed: American Samoa, Cook Islands, Federated States of Micronesia, Fiji, French Polynesia, Guam, Kiribati, Marshall Islands, Nauru, New Caledonia, Niue, Northern Mariana Islands, Palau, Papua New Guinea,Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, and Wallis and Futuna. The regions wetlands are classified into seven systems coral reefs, seagrass beds, mangrove swamps, riverine, lacustrine, freshwater swamp forests and marshes.
There is growing evidence that seagrasses are experiencing declines globally due to anthropogenic threats (Short and Wyllie Echeverria 1996, Duarte 2002, Orth et al. 2006). Runoff of nutrients and sediments that affect water quality is the greatest anthropogenic threat to seagrass meadows, although other stressors include aquaculture, pollution, boating, construction, dredging and landfill activities, and destructive fishing practices. Natural disturbances such as storms and floods can also cause adverse effects.
- A defining feature of the Pacific is the Western Pacific Warm Pool ecosystem. The limited land base of the area is distributed among 200 high islands and 2,500 low islands and atolls. All
participating islands lie in the tropical zone and experience sea surface temperatures that rarely fall below 20 degrees Celsius. In general, the islands increase in size from east to west such that over 83% of the region's land mass is situated in Papua New Guinea, and most of the rest is in the other Melanesian countries and territories.
Historical reports of an earthquake in Tonga in 1865 November identify it as the only event from that subduction zone which generated a far-field tsunami observable without instruments.
Run-up heights reached 2 m in Rarotonga and 80 cm in the Marquesas Islands. Hydrodynamic simulations require a moment of 4 x 1028 dyn cm, a value significantly larger than previous
estimates of the maximum size of earthquake to be expected at the Tonga subduction zone. This warrants an upwards re evaluation of the tsunami risk from Tonga to the Cook Islands
DEFINITION - Percentage native forest cover of total land area
PURPOSE- Indicates the suite of environmental values associated with forests (e.g. biodiversity, carbon sequestration, subsistence hunting)
DESIRED OUTCOME - Stable or positive trend in tree cover, or reduced rate of tree cover loss
DEFINITION - E. coli levels in water samples
PURPOSE - E. coli are indicators of faecal contamination in freshwater bodies and are associated with a range of possible human diseases. High levels of E. coli can be associated with cloudy water and decreased dissolved oxygen
DESIRED OUTCOME - E. coli threshold at or below globally accepted standards for drinking and bathing water, which is none detectable per 100 mL for both E. coli and total coliforms for drinking water; standards vary for bathing and swimming water
DEFINITION - % of total arable land that is under cultivation
PURPOSE - Tracks the area of arable land that is developed for agriculture
DESIRE OUTCOME - Stable trend in area under cultivation. A decreasing area under cultivation might affect food security and an increasing trend under area under cultivation implies some conversion of natural vegetation to agriculture
DEFINITION - % cover of wetlands, mangroves, and seagrass
PURPOSE - Wetlands, mangroves and seagrass provide ecosystem services not provided by other ecosystems (such as nurseries for economically important fish species, natural flood mitigation and water filter systems). They also support plants and animals not found in other ecosystems.
DESIRED OUTCOME - Stable or positive trend in area of wetlands and mangroves
DEFINITION - % of live coral cover in coastal and marine environments
PURPOSE - Indicator of overall health of reef ecosystems. These ecosystems provide important services for humans
DESIRED OUTCOME - Stable or positive trend in live coral cover
DEFINITION - Enterococci levels in water samples
PURPOSE - Enterococci are bacteria found in the intestines of animals and humans and indicate the presence of faecal pollution in coastal waters
DESIRED OUTCOME - Enterococci levels are within the safe threshold for marine recreation at all monitored sites. Current United States EPA thresholds are
DEFINITION - Trends in biomass of tuna species
PURPOSE - Track the health of this important component of the ocean ecosystem
DESIRED OUTCOME - Stable biomass catch
DEFINITION - Fish biomass for inshore fish populations
PURPOSE - Indicates inshore fish population status and reef health
DESIRED OUTCOME - Stable level of biomass; or juvenile fish are not overrepresented in markets
DEFINITION - % of plastic in waste audits, including beach clean-ups
PURPOSE- Determine trends in marine plastic pollution from land and at-sea sources
DESIRED OUTCOME - Stable or declining trend in proportion of plastic in waste audits
