Case
Increasingly changing climate conditions, rising temperatures, and decreasing precipitation has contributed to wildfires, droughts, hurricanes, and floods posing a serious threat to people and the planet. The devastating impact of climate change is no different in the coastal regions. Coastal erosion is one of the alarming aftermaths of human activities and environmental changes making the coastal dynamic action (wave, current, wind) lose balance in the coastal processes and the long-term loss of sediments of coastal zone leading to the destruction of coastline retreat and beach erosion.
At present, coastal erosion has become a very common phenomenon, resulting in the erosion of about 70 percent of the sandy coast worldwide. According to a technical report by India’s National Centre for Coastal Research (NCCR) under the Union Ministry of Earth Sciences, 32 percent of India’s coastline underwent sea erosion and 27 percent of it expanded between 1990 and 2018. As per the IPCC 6th assessment report, coastal areas will see continued sea-level rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas and coastal erosion. Extreme sea-level events that previously occurred once in 100 years could happen every year by the end of this century.
