The coastal regions of Kerala are experiencing a humanitarian crisis as recurring tidal flooding forces residents to abandon their homes and livelihoods. This phenomenon, exacerbated by climate change, has transformed idyllic coastal villages into uninhabitable zones, creating a new category of climate refugees.

Over the past decade, the sea level along Kerala’s coastline has been rising at an alarming rate of nearly 5 mm per year. This increase, driven by global warming and the consequent thermal expansion of seawater, has led to frequent and prolonged tidal flooding. These floods are no longer temporary; the saline water often remains, causing lasting damage to homes, agricultural lands, and infrastructure.

In panchayats like Kumbalangi and Puthenvelikkara, many families have already fled their homes due to the constant inundation. Those who stay behind face daily struggles as routine tasks such as cooking, caring for children, and assisting the elderly become nearly impossible. The rising tides have destroyed traditional livelihoods like fishing and paddy farming, as the saline water renders the land barren and unsuitable for agriculture.

The plight of the residents is compounded by the lack of adequate data and attention from authorities. Despite the gradual but devastating impact of tidal flooding, it has not received the same focus as other natural disasters. This oversight leaves communities without the necessary resources and support to adapt and survive. Women, in particular, bear the brunt of these challenges, managing household chores and caring for family members amidst increasingly harsh conditions.

In Munroe Thuruthu, a cluster of islets in Kerala, the situation is dire. At least families have left their submerged properties, and those who remain face a bleak future. High tides flood homes regularly, with water levels refusing to recede for months. This persistent flooding has forced many residents to wade through filthy water daily, severely disrupting their lives and health.

Efforts to address the crisis have begun but are still in their infancy. Community-driven initiatives in Puthenvelikkara and similar areas have started collecting data and implementing resilience programs. These projects aim to develop sustainable solutions to manage and mitigate the effects of tidal flooding. Local activists and scientists emphasize the importance of equipping communities with the knowledge and tools to adapt to these changing conditions.

However, the road ahead is challenging. The environmental degradation caused by rising sea levels is compounded by human activities such as the construction of dams and rail routes, which further disrupt the natural balance. Experts call for comprehensive strategies to protect these vulnerable ecosystems and support the displaced populations.

The story of Kerala’s coastal communities is a stark reminder of the human cost of climate change. As sea levels continue to rise, more regions may face similar fates, making it imperative for global and local actions to address these pressing environmental issues. The resilience and adaptation of these communities will depend on sustained support and innovative solutions to ensure their survival in the face of an uncertain future.
