Nestled at the confluence of Ashtamudi Lake and the Kallada River in Kerala, Munroe Island has recently emerged as a sought-after tourist destination. Once known mainly to locals and a handful of travelers, the island has gained immense popularity in recent years, especially after the COVID-19 lockdowns. Today, many visitors describe it as Kerala’s second Venice after Allappuzha, drawn by its tranquil waterways, lush landscapes, and calm village lifestyle away from the bustle of the cities.
The Charm of Munroe Island
What makes Munroe Island special is not just its scenic beauty but its way of life. Visitors row through narrow canals in traditional canoes, passing beneath tunnels formed by overhanging mangroves. These natural green corridors create an almost magical experience.
The journey through the winding waterways is as captivating as the destination itself. The calm backwaters, fresh air, silence, and absence of crowds offer a welcome escape from city life. Add to that the hospitality of local residents, fresh fish cuisine, and stunning views of the lakes, and it is easy to understand why tourism has flourished here.
Munroe Island Climate Change Story Beneath the Beauty
Yet beneath this picturesque landscape lies a troubling reality.
Visitors to Munroe Island often notice that they must duck while passing under around eleven bridges during canoe rides. In some places, the clearance between the water and the bridge is surprisingly low, forcing passengers to crouch to avoid hitting their heads.
This is not merely a quirky tourist experience. The clearance between the water and bridge was high enough for someone to stand on the canoe and row. But over the year the clearance has decreased for many for the bridges. For many residents, it is a visible sign of a deeper environmental crisis.
The low clearance suggests that water levels have risen over the years, or that the land itself is sinking—or perhaps both.
Munroe Island has increasingly become a subject of discussion among researchers, environmentalists, and local communities because of concerns about land subsidence and flooding. Some lands of the islands have submerged in water and people have migrated. Now the locals claim that the islands will be submerged by 2050. However there is no scientific consensus that the islands will vanish.
Why Is Munroe Island Sinking?
Residents and experts point to several factors.
Climate Change
Climate change is often cited as one of the reasons for rising water levels and increasing flooding. Changes in rainfall patterns, sea-level rise, and more frequent extreme weather events can all affect low-lying islands like Munroe.
Reduced Sediment Flow
Historically, rivers carried sediments that naturally replenished the island. The landmass of Munroe Island consists largely of soft alluvial soil deposited over centuries.
However, the construction of dams upstream has reduced the amount of sediment reaching the island. Without this natural replenishment, the land gradually subsides and loses its ability to recover from erosion and compaction.
High Tides and Saltwater Intrusion
Residents recall that high-tide flooding was once limited to certain periods of the year. Today, flooding occurs frequently throughout the year.
Many wake up in the morning to find water entering their homes overnight. Saltwater intrusion has also become a growing concern, affecting agriculture and freshwater resources. The saltwater corrodes and weakens the houses
Human Interventions
Climate change alone cannot explain the challenges facing Munroe Island. Human interventions such as unplanned construction, changes in water flow, land-use alterations, and infrastructure projects may also contribute to the problem.
These factors interact with natural processes, making the situation more complex than a simple climate change narrative.
Kerala’s Emerging Paradise and a Warning from Climate Change
Munroe Island offers an important lesson for the world.
It demonstrates how environmental changes in one location can affect communities elsewhere. A dam built upstream may alter sediment flow downstream. Infrastructure projects may unintentionally affect fragile ecosystems. Climate change amplifies these vulnerabilities.
The people experiencing the consequences are often not those directly responsible for the environmental changes.
In many ways, Munroe Island serves as a miniature model of what is happening across the globe—where communities are grappling with rising waters, changing ecosystems, and uncertain futures.
Adapting to a New Reality
Despite the challenges, the people of Munroe Island continue to adapt.
Traditionally, the local economy revolved around coconut cultivation and coir production. However, increasing salinity and flooding have damaged many coconut trees, affecting livelihoods.
In response, residents have diversified their income sources. Some have turned to fish farming, while many others have embraced tourism through homestays, canoe services, and cultural experiences for visitors.
People are also exploring ways to make their homes more resilient to flooding and changing environmental conditions.
Their determination to remain on the island reflects a deep attachment to their land and identity.
What Does the Future Hold?
There are concerns that parts of Munroe Island could face increasing inundation in the coming decades. While predictions vary and the exact future remains uncertain, the island’s environmental challenges are real and deserve serious attention.
Solutions will require a combination of climate adaptation, scientific research, sustainable development, better water management, and careful planning that respects the fragile ecology of the region.
More Than a Tourist Destination
To most visitors, Munroe Island is a beautiful destination filled with serene canals, mangrove tunnels, and unforgettable sunsets.
But for those who look deeper, it is also a place that tells a larger story—a story about climate change, environmental management, human intervention, resilience, and survival.
Munroe Island is not merely a tourist attraction. It is a living reminder of how closely human lives are connected to the health of our ecosystems. Its future may offer valuable lessons not only for Kerala but for coastal and riverine communities around the world that bear the consequence of climate change.
