The fiscal and social cost of ameliorating the impact coastal erosion resulting from climate change is an increasing burden for states, in developing nations physical interventions implemented may present a double agony - debt levels potentially obstructing livelihoods rural coasts. Against this background, study was conducted to explore hard-engineered protection on vulnerability community Ghana using combination Unmanned Aerial Vehicles (UAV), geographic information system tools survey. Shoreline analysis by application Digital Analysis System (DSAS) with aerial photographs 2005 2022 reveals average statistical rate -1 m/year shoreline beaches. A computation indices fourteen beaches, incorporating as additional parameter shows that east west, structures slowed erosion, whereas unprotected beaches have highly eroded, stressing importance protection. In consequence, has dire livelihood-reduction implications inhabitants who are predominantly artisanal fishers. lack acceptable consultation communities exacerbates effects these hard-engineering interventions. high concerns Dzita, Ada, Sakumono, Glefe, Apam, Anlo, Busua. To safeguard vulnerable communities, we support shift hard engineering more integrated nature-based management approaches national scale since most parts coast now susceptible contrast what previously observed only eastern part vulnerable.
