AB - <jats:p>Small Island Developing States (SIDS) are a group of 58 nations identified by the United Nations as facing unique sustainability challenges, including high exposure to climate change, lack of data, and limited resources. The effects of climate change are already observed in SIDS, notably an increase in the magnitude and frequency of natural disasters, marine biodiversity loss, ocean acidification, coral bleaching, sea-level rise, and coastal erosion. The coastal zone is considered to be the main economic, environmental, and cultural resource of SIDS. Monitoring coastal changes is therefore essential to protect communities, biodiversity, natural landscapes, and their economies, as well as to help them adapt to and mitigate against climate change.This talk presents the use of remote sensing data to monitor and analyse the evolution of small islands. Open-access satellite missions, namely Landsat (NASA) and Sentinel (ESA), provide imagery with spatial resolutions of 10 to 60 metres and temporal resolutions of 5 to 16 days. These capabilities enable the retrieval of high-temporal-resolution time series of coastline positions across islands worldwide.A specific focus is placed on the Maldives (Indian Ocean) due to its low elevation and extensive human interventions. Existing literature lacks a comprehensive understanding of the patterns of coastal changes, as well as the main anthropogenic and environmental drivers involved, which operate across diverse temporal (e.g., daily, seasonal, multi-decadal) and spatial scales (e.g., site-specific or atoll-wide). Maldivian coastlines are not systematically or frequently monitored, such that sub and interannual variability and the geomorphological responses to climate forcings, such as the Indian Monsoon and the Indian Ocean Dipole, are not understood.To address this research gap, a data-driven framework was developed, leveraging remote sensing, in situ measurements, and open-access databases. This framework quantif
