Pacific islands are long-settled by mankind, dating back several hundreds to thousands of years ago since discovery by islanders traveling by boat. Amongst these islands are atoll islands, which are small coral islands that lie at a low elevation and are usually part of a ring-like coral reef formation. Past and present islanders collect water from rainwater catchments and groundwater wells, with rainwater used primarily for drinking water and groundwater used as a supplement for wash water. Unfortunately, this region can experience severe drought, over-wash events during strong tropical storms, and typhoons, all of which threaten the freshwater supply for these islands. Due to rising concerns over climate change, there is interest in studying the water security of these especially vulnerable land forms. This thesis evaluates the reliability of the water supplies on four atoll islands in Yap, Micronesia by modeling the reliability of the two main sources. To first analyze rainwater catchment performance, Ifalik Island is evaluated using data collected on the island in 2015 by a collaborative research field team and a water balance model. Second, the results are used to develop design curves as a tool for rainwater catchment design and improvement. The fresh groundwater source is also modeled for each of the four islands to test the effects of varying climate conditions on the shallow, freshwater lens. Rainwater catchment systems on Ifalik Island are evaluated for their performance using a mass balance model that quantifies water storage through time. Performance is quantified primarily by reliability, which is a term to represent the percentage of days a rainwater catchment supplies sufficient water to the users. Based on the data from the Ifalik field survey, ii the average household rainwater catchment system on Ifalik uses a 16.5 square meter guttered roof with a 2,000 liter storage tank and serves seven individuals at 12 liters per capita per day. As a result of a rainwater catchment system sensitivity analyses based on the average rainwater catchment conditions, the most important factors in performance are effective roof area size, water demand, and gutter-downspout efficiency. Further analyses using the mass balance model found that the performance of each individual catchment is sufficient to provide water to the community during conditions similar to the severe drought year of 1997-1998, as well as projected rainfall conditions for the next 30 years. Therefore, analyses suggest Ifalik Island has sufficient rainwater catchment performance to provide water for the community. However, to introduce a conservative measure for water security, it is recommended that the catchment area be extended to the full size of the roof area. This would thereby increase the storage supply for the community by 25 cubic meters on the day of lowest supply under the 1997-1998 severe drought conditions.

The new Framework will provide guidance for the region on key priorities for biodiversity conservation and ecosystem management for the next six years with clear linkages to the global Aichi Biodiversity Targets and National Biodiversity Strategy and Acion Plans. climate-sensitive development sectors: coastal zone management, food security and food production, and water resources management. The programme began in 2009 and is scheduled to end in December 2014.

Marine pollution is widely recognised as one of the four major threats to the world’s oceans, along with climate change, habitat destruction and over-exploitation of living marine resources. Spills of oil and other chemicals into the marine environment, both from ships and land-based sources, is a significant source of pollution. In a region sometimes called ‘Oceania’, the health of the ocean is fundamental to the sustainability of all aspects of Pacific island life. The importance of coastal and marine environments to every aspect of the lives of Pacific islanders cannot be overstated, and the impacts of marine spills constitute a major concern for Pacific island peoples. Because of a lack of major land-barriers throughout the Pacific, combined with a complex pattern of trans-oceanic currents, the Pacific Ocean is perhaps the most highly connected and continuous ocean, in terms of water movement, on the planet. This compounds the seriousness of marine pollution for the region. Events in one area can have implications for other areas, as pollutants and contaminants are carried from their sources by ocean movements.

Coastal communities in the Pacific are without doubt some of the most vulnerable to climate change effects in the world. The limited land area in some countries and low profile of atolls (many only 3m above sea level at high tide) exacerbate the vulnerability of these locations, and the governments and people of these countries have limited capacities and resources to cope at all levels.

Life on Earth is disappearing fast and will continue to do so unless urgent action is taken. Well designed and effectively managed systems of protected areas are a vital tool for reducing biodiversity loss while delivering environmental goods and services that underpin sustainable development. There are currently over 130,000 protected areas worldwide, covering around 13.9 % of the Earth’s land surface and 5.9 % of the territorial marine surface. These areas represent a tremendous resource for conserving biodiversity and for protecting vital ecosystem services. The world’s protected areas exist in a rapidly changing world. There are many issues facing protected areas, including climate change, invasive species, fragmentation of natural ecosystems, increasing urbanisation and growing demands upon natural resources. Consideration of protected areas must be framed within this context of global change

Climate change poses an unprecedented level of threat to life on the planet. In addition, predictions about the scale and speed of impact are continually being revised upwards, so that what was already a serious situation continues to look even more threatening. The facts are well known. Atmospheric greenhouse gases are creating warmer temperatures, ice melt, sea-level rise and an unpredictable climate, with a range of extremely serious and hard-to-predict consequences. Recent research shows an increasingly bleak picture. During the period of writing this report new information suggests that: we may already be too late to prevent widespread collapse of coral reef systems due to ocean acidification; climate change adaptation will cost US$75-100 billion a year from 2010 onwards for developing countries according to the World Bank; and climate change may move faster than expected with average temperatures rising 4ºC by 2060 compared to pre-industrial levels according to the UK Meteorological Office. But serious as the situation has now become, much can still be done to reduce the problems created by climate change. This report focuses on the role that protected areas can play in mitigating and adapting to climate change; a set of options that hitherto has been under-represented in global response strategies. In the rush for “new” solutions to climate change, we are in danger of neglecting a proven alternative.

Ecosystem-based Adaptation (EbA) integrates the use of biodiversity and ecosystem services into an overall strategy to help people adapt to the adverse impacts of climate change. It includes the sustainable management, conservation and restoration of ecosystems to provide services that help people adapt to both current climate variability, and climate change1. Ecosystem-based Adaptation contributes to reducing vulnerability and increasing resilience to both climate and non-climate risks and provides multiple benefi ts to society and the environment.

As environmental problems continue to increase at an ever more rapid rate, exacerbated by the major threat of global climate change, the need for widespread remedial action is becoming ever more pressing. Scientific consensus on both the root causes of these problems and the measures required to tackle them is growing, while mass media and public interest has reached fever pitch. Of course, while this has put pressure on decisionmakers to take positive action, the realisation of the gravity and extent of the environmental problems has encouraged all those concerned about the state of our world to search for partners around it: one such significant partnership to e­merge in recent years is between those concerned with the conservation of nature –and of its biodiversity– and the custodians of sacred sites, representing both indigenous beliefs and mainstream faiths.
