This Watershed Assessment (WA) was initiated in response to the damage caused by Tropical Cyclone Gita in February 2018, which led to infrastructure damage, power outages, and widespread flooding in American Samoa. The assessment recognizes the resilience of Pacific Islanders' cultures and traditional governance and aims to provide recommendations, both within and outside of USACE authorities, to enhance the resilience of American Samoa to future natural hazards.
This is 2003 Agricultural census data for American Samoa.

This report presents findings from the analysis of radiocarbon dates and volcanic stratigraphy in the Leone Volcanics region of Tutuila Island, American Samoa, shedding light on the timing and spatial distribution of late-Holocene volcanic events. Key insights include identifying a distinct reddish ash stratum dating to approximately AD 650-750 as the most recent eruptive event, along with observations on the source and sequence of ash deposits, suggesting multiple eruptive events from both seaward and inland craters, potentially continuing as recently as AD 1300.
This paper presents over 100 radiocarbon dating results for Tutuila and Manu'a in American Samoa, contributing to various aspects of Samoan archaeology.
This paper delves into the agriculture and livestock use in American Samoa.
This map shows the different geology present on Tutuila, American Samoa. Scale approximately 1:60,000. 39 x 86 cm. "Contour interval on land, 200 feet. Soundings in fathoms." Shows diagrammatic structure sections, sedimentary and volcanic rocks, and great erosional unconformity.

Climate change profoundly affects global agriculture, posing food security threats via extreme weather, temperature shifts, and rainfall variations. In the Pacific Islands, additional challenges like sea-level rise and ecosystem degradation exacerbate these issues. The American Samoa Extension Climate Forum, conducted on June 20-21, 2018, sought to address these concerns by engaging stakeholders in discussions about sustainable agriculture, climate adaptation, and food security.
Pacific Island Developing Countries (PIDCs) contribute a minuscule 0.03 percent to global carbon dioxide emissions, with residents producing only a quarter of the world's average emissions per person. However, despite their minimal emissions, these nations are expected to face some of the earliest and harshest consequences of climate change, with a particular focus on its impact on freshwater resources. This chapter delves into the potential threats posed by climate change to the already stressed freshwater supplies in PIDCs.
In response to climate change impacts like rising sea levels, efforts are being made in the Pacific Islands region to assess and adapt to the effects on mangroves. This includes improving management practices, reducing stress on mangroves, and integrating climate data into land-use planning to minimize risks to coastal ecosystems and human safety.
This chapter explores the complex interactions within the climate system, emphasizing the significance of understanding climate's physical and social impacts at various scales. It underscores the importance of assessing vulnerability to climate conditions, focusing on sensitivity, exposure, and resilience, especially in Pacific Island communities facing climate-related challenges.
This report, part of the Pacific Islands Regional Climate Assessment (PIRCA), discusses climate change indicators and their impacts on key sectors in American Samoa. PIRCA, a collaborative effort involving various stakeholders, aims to inform and prioritize actions in response to climate change in the US-Affiliated Pacific Islands and the Hawaiian archipelago.
This project focuses on assessing American Samoa's vulnerability to natural hazards and the impacts of climate change. It engaged with the community through an online survey, interviews, and a preparedness workshop in Pago Pago. The goal is to help residents and professionals in American Samoa prepare for future hazard events and climate change impacts, providing information, stories, and guidance on disaster and climate change preparedness
Following the 2009 Samoa-Tonga earthquake, the Samoan islands, including Savai'i, Upolu, and Tutuila, have experienced accelerated sea-level rise, driven by subsidence and gravity changes, with American Samoa witnessing a 5 times faster rate than the global average. A viscoelastic model predicts a continued sea-level rise of 30-40 cm, intensifying coastal flooding.
The absence of historical sea-level data for the Pacific over the past 1,000 years hinders our understanding of late Neogene sea-level changes. Data from tectonically stable sites in various Pacific locations suggest that sea level was close to its present level around 1,000 years ago, rose to approximately 0.9 meters above present levels around 700 years ago during the Little Climatic Optimum, then fell during the Little Ice Age before gradually rising again over the past 200 years.

The data described here is from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted in Aua Reef, American Samoa, by scientists of the Ecosystem Sciences Division (ESD) of the NOAA Pacific Islands Fisheries Science Center (PIFSC). The NOAA Fisheries, Ecosystem Sciences Division established 18 survey sites along the water quality gradient near land-based source pollution. This is part of a larger collection of datasets collected as part of the CRCP-funded project 'Linking watershed management activities to reef health in American Samoa' (project no. 31303).
This booklet describes the U.S. Army Corps of Engineers' role in water resources development and the Pacific Ocean Division and Honolulu Engineer District have been assissting the Government of American Samoa in the management and development of the territory's water resources. The "urbanization" of American Samoa and the accompanying desires for modern conveniences have placed heavy demands on the territory's fragile infrastructure, including its vital resource.
