Global Sand Crisis: Maldives Land Reclamation Highlights Unsustainable Extraction

Core Event – Maldives’ Gulhifalhu Land Reclamation and UN Sand Report
In 2019 the Maldives government hired a Dutch firm to reclaim 192 ha (475 ac) of lagoon on Gulhifalhu, near Malé. The project required 24.5 million m³ of sand dredged from 13.75 km² of the northern Malé atoll. Six months after work began, an environmental assessment warned that the damage would be irreversible. A new United Nations Environment Programme (UNEP) report released in 2026 warns that sand extraction worldwide is exceeding natural replenishment, threatening ecosystems and climate resilience.
Background – Sand’s Dual Role in Development and Ecosystems
Sand is the most exploited solid natural resource on Earth. It underpins concrete, asphalt, glass for solar panels, and foundations for roads and buildings. Simultaneously, “alive” sand regulates rivers, buffers coastal floods, filters water, and supports coral reefs, mangroves, seagrasses, and the biodiversity that sustains fisheries and tourism.
Key Figures & Organizations
- Pascal Peduzzi – Director, UNEP Global Resource Information Database, Geneva.
- UNEP – Author of the 2026 sand-resource report and the Marine Sand Watch tool.
- Maldives Government – Initiator of the Gulhifalhu reclamation.
- Dutch reclamation contractor – Executed the sand-dredging (unnamed in sources).
- Kimberly M. S. Cartier – Staff writer summarising the UNEP recommendations.
Data & Statistics
- Global sand use: 50 billion metric tons / year.
- Projected demand increase: +45 % by 2060.
- Half of sand-dredging firms operate inside marine protected areas (MPAs), accounting for 15 % of dredged volume.
- Maldives project: 24.5 million m³ sand, 200 ha coral reef destroyed.
- Philippines airport project: 155 million m³ sand, fishing collapse.
- Indonesia urban development: 22 million m³ sand, 80 % income loss for fishers.
- >80 % of Maldives land lies < 1 m above sea level.
Why It Matters – Ecological and Climate Implications
The UN report links sand extraction to loss of habitats for fish, turtles, birds, and crabs, undermining fisheries, tourism, and natural defenses against sea-level rise and storm surges. In climate-vulnerable nations like the Maldives, reduced coastal protection amplifies the risk of inundation and “urban disaster” outcomes.
Official Statements & Responses
UNEP emphasizes sand as “our first line of defence against sea level rise, storm surges, and salination of coastal aquifers.” The agency urges nations to treat sand as a strategic asset, create national inventories, establish regional planning groups, promote circularity in building materials, strengthen environmental safeguards, and embed sand-related biodiversity risks into financial decision-making. A technical analysis of the Gulhifalhu land-use plan labels the newly created landmass as engineered for “urban disaster.”
Criticism & Opposition
An environmental assessment concluded the Maldives damage would be irreversible. The Philippines and Indonesia cases illustrate how sand dredging can devastate fishing communities. Critics argue that current governance lacks transparency, adequate mapping of ecologically sensitive zones, and enforcement of existing environmental rules.
Conflicting Reports & Gaps
Sources provide no official response from the Maldivian authorities regarding the assessment findings. Post-project monitoring data on reef recovery are absent, leaving the long-term ecological trajectory uncertain. Quantitative valuations of sand’s ecosystem services remain under-reported, hindering cost-benefit comparisons.
Verbatim Quotes
- “Sand is sometimes referred to as the unrecognised hero of development, but its essential role in sustaining the natural services on which we depend is even more overlooked. Sand is our first line of defence against sea level rise, storm surges, and salination of coastal aquifers – all hazards exacerbated by climate change.” — Pascal Peduzzi, UNEP Director
- “The result will be the loss of critical habitats for fish, turtles, birds, crabs, and other species supporting ecosystems, fisheries and tourism, the report said.” — UN report
- “Over-reliance on short-term economic metrics risks obscuring, and further impacting, the geological and ecological processes that take centuries to form and may not be restored once critical thresholds are crossed,” — UN report
- “What is hardest to measure may be precisely what sustains both nature and human societies over the long term. The challenge ahead is not only to manage extraction, but to recognise and balance the full spectrum of sand’s values.” — UN report
- “Sand is the most exploited solid natural resource on Earth.” — UN report
What’s Next – Governance and Sustainable Sand Management
UNEP recommends establishing sand as a strategic national asset, creating comprehensive inventories, and forming regional planning bodies that integrate sand into climate-resilience strategies. It calls for circular construction practices, stricter protection of MPAs, transparent supply-chain reporting, and financial frameworks that internalise biodiversity and social risks. Implementation of these measures will determine whether sand extraction can be aligned with long-term ecological sustainability and the survival of low-lying nations.
