Salinity intrusion, exacerbated by sea level rise and coastal erosion, poses a significant threat to the availability and quality of surface water and groundwater reserves. The intrusion of saltwater into freshwater sources leads to contamination, rendering them unfit for consumption and irrigation. This not only jeopardizes the health and well-being of communities that rely on these resources but also undermines their economic livelihoods, particularly those engaged in agriculture. As salinization continues to escalate, the uncertainty and unpredictability of crop yields and harvests intensify, affecting food security and exacerbating poverty and inequality. Therefore, urgent action is needed to mitigate the impacts of salinity intrusion, including the implementation of adaptive measures such as improved water management, coastal protection, and alternative livelihood options.
