Lagos Faces Rising Threats: Annual Flooding and the Perils of Sand Mining

Residents of Lekki, a prominent district in Lagos, are no strangers to the annual flooding that increasingly threatens their homes and livelihoods. The city of Lagos, one of Africa's largest and most vibrant metropolises, is grappling with severe environmental challenges exacerbated by sea level rise and significant land subsidence, sinking at an alarming rate of up to 87 mm per year.

The capacity of Lagos to manage these floods is severely undermined by poorly maintained waterways and drainage systems. As the city rapidly expands, fueled by population growth and the influx of people from rural areas seeking better economic opportunities, its infrastructure struggles to keep pace. Compounding these issues is a clandestine yet burgeoning industry that poses a deadly threat: sand mining.

Sand mining along Nigeria's shorelines, driven by the construction boom, is causing extensive coastline erosion and the destruction of vital coastal ecosystems. These ecosystems are crucial for protecting the city’s inhabitants from storms and rising seas. In the past decade alone, Lagos has lost 59 percent of its wetlands, a staggering figure directly linked to the intensifying flood problems displacing thousands of residents annually. The short-term economic benefits of sand mining, enabled by lax regulations, jeopardize the long-term stability and safety of numerous Lagos communities.

As grandiose building projects rise for the affluent, vulnerable populations are continuously pushed to the city's margins and into harm’s way. The relentless sand mining exacerbates their plight by eroding coastal defenses and damaging ecosystems that provide critical services such as fisheries and coastal protection.

The menace of sand mining is projected to escalate, posing an even graver threat to Lagos residents in the coming decades. By 2050, climate change is expected to double precipitation rates, heightening the risk of severe flooding. By 2100, sea level rise could leave half of Lagos underwater, displacing countless individuals in vulnerable areas.

The broader context reveals a global crisis driven by the insatiable demand for sand and gravel, essential materials for construction. This demand fuels unsustainable and often illegal mining practices, degrading ecosystems and increasing vulnerability to natural disasters. Despite being one of the most traded commodities globally, second only to water, sand remains largely overlooked in government policies and public discourse.

Addressing the sand mining issue is imperative for sustainability and reducing future risks, particularly in cities like Lagos. Policymakers and urban planners must prioritize the maintenance of waterways and drainage systems, enforce strict regulations on sand mining, and invest in resilient infrastructure to safeguard the city's future.

As Lagos continues to develop, a balanced approach that considers both economic growth and environmental sustainability is crucial. The city must adopt innovative solutions to manage urban expansion while protecting its natural defenses against flooding and sea level rise.

For residents of Lekki and beyond, awareness and advocacy are key. Understanding the hidden threats posed by sand mining and pushing for comprehensive policy changes can help mitigate the risks and secure a safer, more sustainable future for all of Lagos.

Residents and stakeholders are encouraged to engage with local authorities and environmental organizations to advocate for better regulation and sustainable practices.
