UNEP's Sand & Sustainability III (May 12, 2026) — extraction hits 50 billion tonnes/year (5x of 1970), building-demand to rise 45% by 2060; report names sand the second-most extracted material after water
Why in News
On May 12, 2026, the United Nations Environment Programme (UNEP) released its third Sand and Sustainability report — titled 'Sand and Sustainability: An Essential Resource for Nature and Development' — co-written by 27 international experts. The headline finding: global sand extraction has hit roughly 50 billion tonnes a year, up from 9.6 billion tonnes in 1970 — a fivefold increase at an average annual growth rate of 3.2%. The report warns of a 'sand gap': humans are extracting sand faster than it can be replenished by nature, threatening river morphology, coastal protection, biodiversity and the livelihoods of an estimated 2.3 billion people who depend on small-scale fisheries linked to healthy sandy ecosystems.
Sand is now the second-most extracted solid material on Earth after water in terms of global consumption. Demand for sand for buildings alone is projected to rise 45% by 2060, driven by three structural forces: (a) urbanisation — over 45% of humans now live in cities, with average built-up area per person doubling roughly from 43 sq m in 1975 to 63 sq m in 2025; (b) infrastructure mega-projects — from India's PM Awas Yojana housing and highway expansion to land reclamation in Manila Bay and the Maldives' Gulhifalhu project, which dredged 24.5 million cubic metres; and (c) the silicon-economy demand — semiconductors, solar panels, data centres — for high-purity industrial sand. The global sand market was valued at $569.4 billion in 2024.
UNEP closes the report with 10 strategic recommendations and a sustainability-assessment toolkit. The headline asks: (1) recognise sand as a strategic, finite resource in national policy; (2) integrate biodiversity into sand governance; (3) shift to a circular economy — reuse construction and demolition waste, deploy manufactured sand ('M-sand') from crushed rock; (4) introduce Cumulative Impact Assessments (CIAs) instead of project-by-project clearance; (5) protect Marine Protected Areas (MPAs) from dredging; (6) ban beach mining; (7) standardise data on extraction; (8) empower riverine and coastal communities; (9) use District Survey Reports (DSRs) and Sustainable Sand Mining Management Guidelines (India already follows since 2016/2020); and (10) build a global stewardship framework. For India — where the Chambal, Yamuna, Sone and many other rivers face severe degradation from illegal sand mining — the report is a structural prompt to move beyond enforcement-only to a market plus circularity model.

What the report says
Released on May 12, 2026, the report — the third in UNEP's Sand and Sustainability series — documents that global sand extraction reached ~50 billion tonnes per year (2020 baseline), up from 9.6 billion tonnes in 1970, a fivefold rise at a 3.2% CAGR. Sand is the second-most extracted solid material on Earth after water. The 'sand gap' — the deficit between what humans extract and what nature replenishes — is widening. The 2.3 billion people who depend on small-scale fisheries linked to sandy ecosystems are the front-line losers; coastal protection against sea-level rise is the second-order loss.
Why demand is exploding
Four drivers explain the surge. (1) Urbanisation: over 45% of humans live in cities, and built-up area per person has grown from 43 sq m (1975) to 63 sq m (2025); building demand for sand is projected to rise 45% by 2060. (2) Infrastructure: India's PM Awas Yojana and highway expansion, China's high-speed rail, Southeast Asia's reclamation projects (Manila Bay, Singapore, Maldives Gulhifalhu — 24.5 million cubic metres dredged) — every project consumes massive aggregates. (3) Climate adaptation: ironically, sea walls and raised islands built to protect against the very sea-level rise that mining exacerbates require yet more sand. (4) Silicon economy: high-purity sand feeds semiconductor fabs, solar-panel manufacturing and data-centre construction. The global sand market was valued at $569.4 billion in 2024.
Ecological and livelihood damage
Excessive extraction lowers riverbeds (bed degradation), destabilises banks, alters flow and triggers downstream flooding — visible in India along the Chambal, Yamuna, Son and Damodar. It depletes groundwater (sand is a critical aquifer recharge medium), kills aquatic habitats (gharial, mugger, freshwater turtle), and undermines bridge piers and embankments. On the coast, dredging destroys coral reefs, seagrass and fish breeding grounds. Beach mining accelerates erosion and worsens storm-surge damage. The 2.3 billion small-scale fisheries dependent on sandy ecosystems are the worst hit, with informal-sector livelihoods evaporating quietly.
UNEP's 10-Point Action Plan
The report's 10 strategic recommendations cover: (1) recognising sand as a finite strategic resource in national policy; (2) integrating biodiversity into sand governance; (3) shifting to a circular economy via construction-and-demolition waste recycling and Manufactured Sand (M-sand) from crushed rock; (4) moving from project-level clearance to Cumulative Impact Assessments (CIA); (5) protecting Marine Protected Areas from dredging; (6) banning beach mining; (7) standardising extraction data; (8) empowering riverine and coastal communities; (9) using District Survey Reports (DSR) and Sustainable Sand Mining Management Guidelines (India already has 2016/2020 versions); and (10) building a global stewardship framework. India is named alongside several other countries as having policy infrastructure (DSRs, EC requirements) — the gap is enforcement.

Sand has historically been treated as a 'free' resource — abundant, locally extracted, regulated weakly. UNEP's 2026 report consolidates a decade of evidence that this assumption is no longer defensible. Global extraction has crossed 50 billion tonnes/year (5x 1970), driven by urbanisation, infrastructure mega-projects and the silicon economy. The result is a 'sand gap' between extraction and replenishment, threatening river morphology, coastal protection, biodiversity and the livelihoods of 2.3 billion people. India has a partial governance architecture — MMDR Act 1957, EIA Notification 2006, 2016/2020 SSM Guidelines, DSRs, the Deepak Kumar precedent — but enforcement gaps and sand-mafia violence persist on the Chambal, Yamuna, Son and Damodar.

Connections & Comparisons
- ↔Compare with India's 2016 Sustainable Sand Mining Management Guidelines and the 2020 Enforcement & Monitoring Guidelines — the report calls these out as good scaffolding.
- ↔Recall Deepak Kumar v. State of Haryana (2012) — Supreme Court mandate for Environmental Clearance for all sand mining including minor minerals.
- ↔Link to Article 48-A (DPSP duty of State) and Article 51A(g) (Fundamental Duty of citizens) — environmental constitutional anchors.
- ↔Connect to the UN Sustainable Development Goals — especially SDG 11 (Sustainable Cities), SDG 12 (Responsible Consumption), SDG 14 (Life Below Water) and SDG 15 (Life on Land).
- ↔Compare with the Maldives Gulhifalhu project (24.5 million cubic metres dredged) — climate-adaptation reclamation that itself depends on extraction.
