The Maldives, a tropical paradise renowned for its pristine beaches, luxurious resorts, and vibrant coral reefs, is facing an existential crisis. The very existence of this low-lying archipelago in the Indian Ocean is threatened by rising sea levels caused by climate change.

Formation and Geography of the Maldives

The Maldives consists of 26 atolls, an archipelago of approximately 1,190 coral islands scattered across the Indian Ocean, owes its unique formation to a combination of volcanic activity and the growth of coral reefs over millennia.

Geological Origins

The islands are situated atop the Laccadives-Chagos Ridge, an underwater volcanic mountain range that stretches over 2,000 kilometers. Millions of years ago, volcanic eruptions formed the foundation of these islands. Over time, the volcanic peaks eroded and subsided beneath the ocean’s surface.

Coral Reef Formation

As the volcanic islands sank, coral reefs began to grow around their fringes. Corals are marine invertebrates that secrete calcium carbonate skeletons, which accumulate over time to form massive structures. These reefs acted as natural barriers, protecting the islands from erosion and creating shallow lagoons within their rings.

Atoll Structure

The Maldives is renowned for its atolls, ring-shaped coral formations that encircle a central lagoon. Each atoll consists of numerous coral islands and sandbanks, varying in size and shape. The atolls themselves are grouped into 26 larger administrative divisions.

Geographical Dispersion

The Maldives is one of the most geographically dispersed countries in the world, with its islands spread across an area of approximately 90,000 square kilometers. The islands are low-lying, with the natural highest point¹  reaching only 2.4 meters above sea level. This low elevation makes the Maldives incredibly vulnerable to the impacts of rising sea levels.

Unique Features

The Maldivian landscape is characterized by its stunning white-sand beaches, crystal-clear lagoons, and vibrant coral reefs teeming with marine life. The islands are devoid of rivers and lakes but often feature small marshes and ponds. Some islands also have sand dunes reaching modest heights.

Understanding Vulnerability

The geological and geographical characteristics of the Maldives make it a unique and fragile ecosystem. The low elevation and dispersed nature of the islands render them highly susceptible to environmental changes, particularly the rising sea levels associated with climate change. Understanding the formation and geography of the Maldives is crucial for comprehending the challenges it faces and the urgency of implementing measures to protect this vulnerable paradise.

High Tide, High Stakes: The Maldives’ Battle Against Climate Change

The rising tide of climate change poses a dire threat to the Maldives, an archipelago nation vulnerable to the increasing sea levels brought about by global warming. This phenomenon, driven by human activities that release greenhouse gases into the atmosphere, is causing significant changes to the Earth’s climate system.

The Science Behind Rising Sea Levels

The primary factors contributing to rising sea levels are:

• Thermal Expansion:  As the ocean absorbs heat trapped by greenhouse gases, its water expands, leading to a rise in sea level. 
• Melting Glaciers and Ice Sheets:  The warming climate causes glaciers and ice sheets to melt at an accelerated rate, adding vast amounts of water to the oceans. 

Observed and Projected Sea Level Rise

Global average sea level has been rising at an alarming rate, with the most recent measurements indicating an increase of over 90 mm (3.5 inches) since the early 1990s. The rate of rise has also been accelerating, with projections suggesting an even more significant increase in the coming decades. The Intergovernmental Panel on Climate Change (IPCC) predicts a potential sea level rise of 0.26 to 0.77 meters (10 to 30 inches) by 2100.

Impacts on the Maldives

The Maldives, with its average elevation of only 1.5 meters above sea level, is exceptionally vulnerable to rising seas. The consequences are already evident and are projected to worsen in the future:

• Erosion and Loss of Land:  Coastal erosion is accelerating, causing the loss of valuable land and infrastructure. 
• Saltwater Intrusion:  Rising seas are contaminating freshwater aquifers² , threatening drinking water supplies and agriculture. 
•  Increased Flooding:  Storm surges and high tides are becoming more frequent and intense, causing widespread flooding and damage. 
• Threats to Tourism:  The tourism industry, a cornerstone of the Maldivian economy, is at risk due to beach erosion, coral bleaching, and infrastructure damage. 
• Displacement and Migration:  As islands become uninhabitable, communities may be forced to relocate, leading to internal displacement and potentially international migration.

Mitigation and Adaptation

The Maldivian government has been proactive in addressing the challenges posed by climate change. Initiatives include:

• Coastal Protection:  Construction of seawalls, breakwaters, and other coastal protection measures to mitigate erosion and flooding. 
• Infrastructure Elevation:  Raising critical infrastructure, such as airports and power plants, to protect them from rising seas.

The Grim Reality of Climate Change in the Maldives

The Maldives is experiencing a multitude of devastating impacts and consequences due to rising sea levels, which threaten the very existence of this island nation. These effects permeate various aspects of life and the environment in the Maldives.

Environmental Impacts

• Coastal Erosion:  The relentless pounding of waves and storm surges is accelerating erosion, causing the loss of valuable land and infrastructure. Beaches are shrinking, islands are disappearing, and vital ecosystems like mangroves and coral reefs are being destroyed. 
• Saltwater Intrusion:  As sea levels rise, saltwater seeps into freshwater aquifers, contaminating the limited drinking water supplies and rendering agricultural land unusable. This jeopardizes food security and public health, forcing communities to rely on expensive desalination or imported water. 
• Coral Bleaching and Ocean Acidification:  Rising sea temperatures and increased carbon dioxide absorption by the ocean lead to coral bleaching, where corals expel the symbiotic algae that provide them with sustenance and color. This weakens and kills coral reefs, which are vital for marine biodiversity, coastal protection, and tourism. 
• Loss of Biodiversity:  The destruction of coral reefs and other marine habitats threatens the rich biodiversity of the Maldives. Many species of fish, turtles, and other marine life depend on these ecosystems for survival. The loss of biodiversity also disrupts the delicate balance of the marine food web. 

Socioeconomic Impacts

• Displacement and Migration:  As islands become uninhabitable due to erosion, flooding, and saltwater intrusion, communities are forced to relocate. This leads to internal displacement, with people moving to other islands, and potentially international migration, as some Maldivians seek refuge in other countries. 
• Economic Losses:  The tourism industry, a major source of revenue and employment in the Maldives, is heavily impacted by rising sea levels. Beach erosion, damage to resorts and infrastructure, and the loss of natural attractions deter tourists and threaten livelihoods. 
• Infrastructure Damage:  Critical infrastructure, such as airports, roads, hospitals, and power plants, are vulnerable to damage and destruction from storm surges, flooding, and erosion. The repair and replacement of infrastructure are costly and strain the country’s resources. 
• Public Health Risks:  The contamination of freshwater sources and increased flooding raise public health risks. Waterborne diseases, such as cholera and dysentery, become more prevalent, while the spread of vector-borne diseases like dengue fever is exacerbated.

Notes

1. Is the highest point only 2.4 meters above sea level in the Maldives?

There seems to be some confusion about the highest point in the Maldives.

• Historically: The highest natural point was indeed recorded as 2.4 meters (7 feet 10 inches) above sea level.
• Recent Development: On the island of Villingili, a mound on a golf course was measured at 5.1 meters (16.75 feet) above sea level. This would make it the new highest point, but it is not naturally occurring.

Therefore, depending on whether you consider artificial elevations, the answer varies:

• Natural Highest Point: 2.4 meters (7 feet 10 inches)
• Highest Point (Including Artificial): 5.1 meters (16.75 feet)

It’s important to note that this distinction is crucial in the context of the Maldives’ vulnerability to rising sea levels. Even the higher artificial elevation doesn’t change the fact that most of the country remains dangerously low and at risk.

2. What is an aquifer?

An aquifer is an underground layer of rock or sediment that holds groundwater. This groundwater is the water that has seeped into the ground from rain, snow, or other sources. Aquifers are like giant sponges, storing water in the spaces between the rocks or sediment particles.

There are two main types of aquifers:

• Unconfined aquifers: These aquifers are directly connected to the surface through porous soil. They are replenished (recharged) by rainfall or surface water that soaks into the ground.
• Confined aquifers: These aquifers are sandwiched between layers of impermeable rock or clay, which prevents water from easily entering or leaving the aquifer. They are typically recharged through openings in the confining layers where water can seep in.

Aquifers are important sources of freshwater for drinking, irrigation, and industrial use. They are often tapped into through wells, which pump the groundwater to the surface. However, it is important to manage aquifers carefully to avoid overpumping, which can deplete the water supply and cause environmental problems.

3. What is a litmus test?

In the context of the Maldives’ situation as a “litmus test” for climate action, it signifies that:

• Decisive Test: The Maldives’ fate is a critical indicator of the world’s willingness and ability to address climate change effectively.
• Indicator of Success or Failure: The outcome in the Maldives will demonstrate whether global efforts to mitigate climate change and protect vulnerable regions are successful or not.
• Revealing Priorities: The response to the Maldives’ crisis will reveal the true priorities of governments, organizations, and individuals regarding environmental sustainability and social responsibility.
• Setting a Precedent: The actions taken (or not taken) in the Maldives will set a precedent for how the world deals with similar climate-related challenges in other vulnerable regions.

Essentially, the Maldives is a test case for the global community’s commitment to combatting climate change. If the world fails to act decisively to support the Maldives and mitigate the impacts of rising sea levels, it sends a worrying message about our ability to address this global crisis and protect vulnerable populations and ecosystems. However, if the world rallies to support the Maldives and implement effective solutions, it could inspire hope and demonstrate the power of collective action in the face of climate change.
