The Impact of Climate Change on Coastal Erosion: A Comparative Study of Vulnerable Regions.

This study explores the impacts of climate change on coastal erosion, focusing on how rising sea levels, increased storm intensity, shifting ocean currents, and human activities contribute to the accelerated loss of coastal land. Through a comparative analysis of vulnerable regions--South Pacific Islands, Gulf Coast (USA), Coastal Bangladesh, and the East African Coast--the research highlights the environmental, socioeconomic, and cultural consequences of erosion. It emphasizes the urgent need for comprehensive mitigation strategies, including engineering solutions (e.g., sea walls, groynes, artificial reefs), nature-based measures (e.g., mangrove restoration, beach nourishment, wetland conservation), and robust policy frameworks. The findings underscore that while engineering solutions offer immediate protection, nature-based approaches provide sustainable, long-term resilience by restoring ecosystems and supporting biodiversity. Effective policy and governance, supported by international collaboration and local engagement, are crucial to implementing adaptive strategies that address both regional vulnerabilities and global challenges. This research aims to contribute to a better understanding of coastal erosion dynamics and inform policies that enhance coastal resilience against the impacts of climate change. [ABSTRACT FROM AUTHOR]
