Funafuti, July 24, 2023 – in collaboration with Pacific Neighborhood (SPC)of Tuvalu Coastal Adaptation Undertaking (TCAP) For the primary time, Atoll has delivered a state-of-the-art on-line platform to the Authorities of Tuvalu that can allow the nation to obviously determine, plan and mitigate the dangers of extreme storms ensuing from sea stage rise and local weather change. The free, public platform permits governments, communities and different customers to make sound, risk-based improvement selections about the place to construct, in addition to a essential device for planning for future adaptation.
Land is an especially valuable useful resource for an atoll nation like Tuvalu, which has a complete of solely about 25 sq. kilometers in its 9 atolls, a lot of it lower than a meter above spring tide. The islands are not often various hundred meters throughout, typically a lot smaller. Understanding how coastlines change and flood dangers are essential to the nation’s local weather change adaptation response.
Incorporating a number of instruments into one dashboard, the platform covers all 9 of Tuvalu’s atolls and islands. It contains modeling of sea-level rise and tidal inundation, coastal change detection and monitoring, injury and loss, and instruments to determine vulnerability to marine hazards.
“We warmly welcome this new platform,” mentioned Fatasi Malologa, Director of Lands and Surveys. “It is a highly effective device that can enhance our understanding of coastal hazards, assist inform our improvement plans and the way we adapt to local weather change sooner or later.”
“The local weather disaster is on the doorstep of Tuvalu and different Pacific Island nations,” mentioned Mesrach Worki, UNDP consultant. “We’re delighted to see this new platform – developed with the Pacific group underneath the Tuvalu Coastal Adaptation Undertaking supported by UNDP and the Inexperienced Local weather Fund – supporting the Authorities of Tuvalu with the proof wanted to plan their adaptation response.”
The coastal monitoring device exhibits the change occasionally and because the islands of Tuvalu change – resembling climate and local weather situations, storms and human exercise – the most important concern is sea stage rise, adjustments within the frequency and depth of waves and the deterioration of residing seashores (scrubbing and acidification) that may result in erosion of many seashores.
The one approach to determine such unfavorable tendencies over time is to observe them – the newly launched platform provides that functionality on the nationwide stage.
SPC’s modeling capabilities for coastal environments are among the many greatest on the earth. It was nice to work with them to convey this necessary and cutting-edge work to Tuvalu,” mentioned Arthur Webb, UNDP Coastal Adaptation Specialist and Chief Technical Advisor to TCAP. “With out this type of information, you can not design local weather change adaptation options and long-term methods with out sound, hazard data. This platform supplies the mandatory basis.”
Essential to SPC platform improvement is the acquisition of the lidar baseline survey accomplished in 2019 underneath TCAP. The platform additionally contains tens of hundreds of storm surge fashions with variables resembling storm dimension + wave route + tide + tidal present + sea stage. This enables customers to view native flood threat together with hurricane threat of landslides.
Correct tidal wave modeling on the Tuvalu Islands is extra sophisticated as a result of the seashores in Tuvalu are stuffed with residing reef platforms and reefs. To assist perceive seepage potential in these distinctive environments, bodily modeling was performed on the College of New South Wales, Manly Hydraulics Laboratory, Australia. In these experiments, scale fashions of some islands have been precisely reproduced with scaled waves created to point out precise wave results. The outcomes have been used to calibrate and practice subsequent pc simulations, in addition to to information TCAP’s Nanumea and Nanumaga adaptation designs.
“With the completion of this platform by the Pacific Neighborhood at TCAP, Tuvalu now has a world-class, complete coastal hazards platform that may present data on shoreline change over time, adjustments between island sea stage and land elevation, and storm surge inundation,” mentioned TCAP Undertaking Supervisor Alan Rischer. “We imagine it’s the first freely out there nationwide, high-quality coastal hazard evaluation device for an atoll nation on the earth. Till now, Tuvalu has very restricted data to make sound, risk-based selections about the place to construct and plan our response to local weather change impacts. This adjustments every part.”
With just a few clicks, anybody can now zoom in on any island in Tuvalu with high-resolution aerial photographs to a particular location and discover totally different flooding situations. Knowledgeable customers can entry the datasets and look at an in depth technique information that explains the information, assumptions, and strategies underlying the modeling.
“This Coastal Hazards and Hazards Dashboard leverages ten years of coastal hazard modeling work at SPC in collaboration with UNDP and the Authorities of Tuvalu,” mentioned Hervé Damlamian, head of the Ocean Forecasting and Monitoring Group at SPC. “Additionally it is half of a bigger program of labor to help Tuvalu’s elevated early warning capability and institutional capability, which can straight contribute to the success of Tuvalu’s improvement technique, ‘Te-Kete.’
The platform is anticipated for use by a number of decision-makers and authorities departments, improvement companies and their tasks, in addition to non-governmental organizations and even non-public property consumers.
An instance of use might be within the placement of necessary new group infrastructure resembling faculties. By wanting on the website utilizing the platform, designers and decision-makers can see whether or not the soil has eroded over time or if the land is simply too low mendacity and flooded throughout excessive water occasions. Likewise, the platform can present dangers associated to the results of storms.
Platform-generated information can be a key piece of the puzzle in creating storm early warning techniques, offering useful data on which islands are susceptible to wave injury and flooding, thereby enabling communities to maneuver important property and properties to safer places.
Certainly, the instruments and fashions developed underneath the Tuvalu Coastal Adaptation Undertaking have been accomplished by the SPC crew and the Tuvalu Meteorological Service to develop a 7-day operational storm forecast system for all communities on the nationwide stage (underneath the WMO-led Local weather Threat and Early Warning System initiative or CREWS).
By 2023, a particular effort has been made to combine authorities capability in coastal resilience and adaptation and consumer suggestions into the platform to make the platform straightforward to make use of and built-in with SPC’s nationwide coaching program underneath TCAP.
Within the coming months, customers in authorities departments will likely be skilled within the common use of the dashboard. Chosen authorities customers with GIS capabilities, together with personnel within the land and survey division, will likely be skilled on add information protection to the coastal monitoring element of the system and monitor adjustments over time.
The platform is now out there on-line free of charge at https://opm.gem.spc.int/tcap/house
In regards to the Tuvalu Coastal Adaptation Undertaking
With funding of US$36 million from the Inexperienced Local weather Fund and US$2.9 million from the Authorities of Tuvalu, the 7-year Tuvalu Coastal Adaptation Undertaking is contributing to strengthening the resilience of one of many world’s most susceptible nations to local weather change and sea stage rise. The challenge, applied by the United Nations Improvement Program in partnership with the federal government, is enhancing coastal safety at key places on the islands of Funafuti, Nanumea and Nanumaga. Progressive measures act as buffers throughout storms, the challenge seeks to strengthen the long-term capability of nationwide and island governments and native communities to adapt to local weather change.

In regards to the Pacific Neighborhood (SPC)
The Pacific Neighborhood (SPC) is the Pacific Area’s premier scientific and technical group, proudly supporting improvement since 1947. It’s a world improvement group owned and managed by 27 member nations and territories.
SPC is a key challenge accomplice for TCAP, conducting environmental and social influence, geotechnical, sea stage measurement and wave induction assessments to help TCAP’s work programme. In 2023, SPC will supply a sensible coaching program for Tuvalu authorities officers and different events.
