“…Thus an improved understanding of faro development and time scales and rates of velu infi ll will help better resolve key questions about when and where reef islands form, and where they may establish in the future. These questions are relevant because of the perceived vulnerability of reef islands to sea-level rise (Khan et al, 2002;Woodroffe, 2008), and thus have direct application to ongoing attempts to better constrain variations in the timing of reef island formation.…”

“…The most anticipated physical impacts of sea-level rise on reef islands are shoreline erosion, inundation, flooding, salinity intrusion and reduced resilience of the coastal ecosystem (Khan et al 2002;Leatherman 1997;Mimura 1999;Yamano et al 2007). If the atoll nations disappear, there will be no islands left and nothing to inhabit (Connell 2004).…”

Anthropogenic impacts on water quality of the lagoonal coast of Fongafale Islet, Funafuti Atoll, Tuvalu

Water pollution, evident by negative values of redox potential in waters, occurs at the lagoonal coast located near the densely populated area of Fongafale Islet on Funafuti Atoll, Tuvalu, Central Pacific. Sediment microbial quinone analysis revealed that these coastal sediments exhibit 2.7-10.4 times more microbial biomass, significantly different microbial community structure and low microbial diversity, when compared to an undisturbed natural coastal sediment. Thus, the pollution is chronic. By considering the total land use/coverage on the islet, the situation of septic tank installations, temporal changes in water redox potential and Escherichia coli numbers in the coastal waters and the spatial distribution of acid volatile sulfide in the sediments, we conclude that domestic wastewater is the primary source of pollution. This pollution is proposed to occur via the following mechanism: during ebb tides, domestic wastewater leaking from bottomless septic tanks and pit toilets run off into the lagoonal coast. Tide changes control the pollution load of domestic wastewater.

“…Focusing in on the Maldives, this nation also has particular sensitivities to climate variability associated with the El-Niño Southern Oscillation climate system, increases in sea surface and air temperature, storm activity, ocean acidification and swells, coastal erosion (Ghina, 2003;Hay, 2013;Khan et al, 2002), and coastal flooding (Wadey et al, 2017). The Maldives is also comprised entirely of low-lying islands and the average ground level is only 1.5 metres above sea level which could mean extensive inundation by 2100 (Khan et al, 2002;Sovacool, 2012).…”

ABSTRACT:As climate change accelerates, it brings with it numerous challenges to society and the natural world. Concepts such as vulnerability have emerged as a way of trying to understand people's risk, despite there being a range of variables that can influence vulnerability and its temporal and spatial dimensions. Drawing from the well-known conceptualisation of vulnerability as a function of exposure, sensitivity, and adaptive capacity, this paper seeks to understand what variables are influencing and shaping vulnerability in Laamu Atoll, the Maldives, and produce a base of knowledge for future vulnerability reduction initiatives. Household questionnaires (n=412) were used on Laamu Atoll to ascertain locals' perceptions of vulnerability based on livelihood resources, financial security, and climate-change experiences. Results show that peripherality, as a notion that describes the disparities between 'core' and 'peripheral' islands, is a key factor shaping vulnerability variables on Laamu Atoll. This has prompted an overarching recommendation for peripherality to be considered as a key dimension of vulnerability to climate change and an important consideration for existing and future human development and climate change policy and practice in Small Island Developing States.
