Located in the northern tropical Pacific Ocean, Majuro is the capital of the Republic of the Marshall Islands. Majuro Atoll consists of a large, narrow landmass and a set of smaller perimeter islands surrounding a lagoon that is over 100 square miles in size. The waters surrounding the Majuro Atoll land areas are relatively shallow with poorly mapped bathymetry. However, the Pacific Ocean on the exterior of the coral atoll and the lagoon within its interior consist of deep bathymetry with steep slopes. The highest elevation of the Majuro Atoll is estimated at only 3-meters above sea level, which is the island community of Laura located on the western part of the atoll. At the eastern edge of the atoll lies the capital...

This folder contains 7 excel files with data from a household questionnaire survey (N=199) conducted for the Marshall Islands Climate and Migration project. The fieldwork took place in March and April 2017. Besides the excel file, the folder also contains the original questionnaire in PDF format. The questionniare looked at livelihood, perceptions of climate change and ecosystem services and migration behaviour. The excel files are 1 file for the main questionnaire data and 6 additional files with data from tables in the questionnaire. Each variable in the questionnaire starts with a Leter (A-K) and a number. This refers to the question number in the questionnaire. The databases uses 3 codes for missing values:...

Low-lying island environments, such as the Majuro Atoll in the Republic of the Marshall Islands, are particularly vulnerable to inundation (coastal flooding) whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise). Land elevation is the primary geophysical variable that determines exposure to inundation in coastal settings. Accordingly, coastal elevation data are a critical input for assessments of inundation exposure and vulnerability. Previous research has demonstrated that the quality of data used for elevation-based assessments must be well understood and applied to properly model potential impacts. The vertical...

The Republic of the Marshall Islands (RMI) is a nation of widely dispersed, low-lying coral atolls and islands, with over 100 square miles of land area scattered across 750,000 square miles of ocean. Average elevation for the RMI is approximately 7 feet above mean sea level, but many islands and atolls are much lower. As climate change causes sea level to rise and weather patterns to shift, the Marshall Islands are increasingly having to contend with flooding and drought that damages agriculture, homes, and infrastructure. Residents are increasingly making the difficult choice to leave their home islands in the hope of a more stable future, moving within the country to larger islands or to the United States where...

The Intergovernmental Panel on Climate Change reports that low-lying atolls (ring-shaped islands or island chains made of coral) in the Pacific Ocean are extremely vulnerable to high tide events (“king tides”), storm surge, tsunamis, and sea-level rise. The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people with homes and communities that may be threatened by these climate change-related events. Policy makers, planners, and others within RMI are faced with decisions about how to prepare for the future and need scientific data and information about the vulnerability of Pacific Islands to potential climate change impacts like sea-level rise. Topographic and bathymetric...

This study aims to clarify the extent to which Marshallese people are already migrating because of climate change, and the role affected ecosystem services play in their migration decisions. The research also aims to better understand the effects of this migration on migrants themselves, among communities in the RMI (in the capital of Majuro, and on Mejit and Maleolap), and in destination states (Hawai‘i, Oregon, and Washington). Finally, the research provides an analysis of shared views found within Marshallese perceptions on these subjects, which allows for a more fulsome assessment of the current state of well-being for Marshallese migrants, contributes to a more informed discussion regarding whether migration...

The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people; over 27,000 of those people live on the Majuro Atoll, RMI’s capital. Sea level rise threatens the very existence of RMI as high-end projections of sea level rise by the end of the century exceed the average elevation of these low atoll reef islands. Already, waves wash over Majuro during “king tides” when strong winds blow from the west across the broad lagoon, or when there are high open ocean waves. Flooding waves breach island shores in multiple locations and wash into homes, cemeteries, across roads, and into commercial districts. Over the past decade, there has been a widespread exodus of residents...

The Marshall Islands Climate and Migration Project studies the multicausal nature of Marshallese migration, as well as its effects on migrants themselves and on home communities (van der Geest et al., 2019). It does so through people-centred research, seeking the views of Marshallese migrants and their relatives in the Marshall Islands. The research has a special focus on how impacts of climate change affect ecosystem services, livelihoods and migration decisions. This policy brief highlights key findings of the migration component of the research. It presents data and findings on migration patterns, drivers and impacts. It ends with a discussion of the results, with a focus on the tension between being prepared...

Given the potential effect of invasive plants and animals to water fluxes through forests, the invasive-driven degradation of native ecosystems is a topic of great concern for many downstream land and water managers. The infiltration rate determines the partitioning between runoff and infiltration into soil in Hawaiian forests and beyond. Thus, to explore the ecohydrological effects of plant and animal invasion in mesic and wet forests in Hawaii, we measured soil infiltration capacity in multiple fenced (i.e., ungulate-free)/unfenced and native/invaded forest sites along moisture and substrate age gradients across the islands of Hawai‘i and Kaua‘i. We also characterized forest composition and structure and soil...

User’s guide for downloading and using the One Meter Topobathymetric Digital Elevation Model (DEM) for Majuro Atoll, Republic of the Marshall Islands.
As one of the lowest-lying island nation-states in the world, the Republic of the Marshall Islands (RMI) is acutely vulnerable to sea-level rise, flooding, and the associated intrusion of saltwater into crucial freshwater supplies. Persistent drought is further affecting agricultural production in the RMI. Many Marshallese communities are already experiencing these changes and are migrating to larger islands within the RMI and to other countries like the U.S. to, among other things, seek alternative means of making a living and access healthcare. The number of Marshallese residing in the U.S. has rapidly risen over the past two decades, from 7,000 in 2000 to 22,000 in 2010. There is also substantial internal migration,...

This folder contains 2 excel files with data from a household questionnaire survey (N=79) conducted for the Marshall Islands Climate and Migration project.
