The Cambodian Mine Action Centre cleared 75,132 hectares of landmine- and unexploded-ordnance-contaminated land in the first half of 2026 — 82 percent of its full-year target, achieved in six months [S-850]. That is a genuinely large number, and it lands almost entirely in the same six provinces this site’s border-property coverage already treats as elevated-risk: Preah Vihear, Oddar Meanchey, Banteay Meanchey, Battambang, Pursat, and Koh Kong [S-850]. For most readers of this site, landmine clearance is background noise. For anyone evaluating rural, agricultural, or border-adjacent land — precisely where Cambodian land is cheapest and least formally documented — it is a due diligence input that deserves its own checklist line, not a footnote.

What CMAC actually reported

The figures, from CMAC’s own July 2026 report covering January–June [S-850]:

  • 75,132 hectares cleared, against an annual target that put the six-month figure at 82 percent of the full year’s goal.
  • 20,861 explosive remnants of war located and destroyed, plus 4,023 emergency call-outs answered from the public.
  • 14,477 mine-risk education sessions, reaching 1,374,887 people — 59 percent of the annual education target.
  • Clearance and survey work intensified in six border provinces affected by Thailand’s 2025 military strikes: Preah Vihear, Oddar Meanchey, Banteay Meanchey, Battambang, Pursat, and Koh Kong. Survey teams assessed 335 of the 349 villages affected in those provinces, covering nearly 387,206 hectares.
  • That work enabled the safe return of 5,911 households across 1,455 hectares, plus 87 schools (154 hectares), 20 health centres, six pagodas, and 114 other infrastructure projects.
  • Nationally, more than 8,400 unexploded ordnance items were destroyed in the period, including 4,436 cluster munitions — the cluster-munition count itself a marker of how much of this year’s work is cleaning up 2025’s conflict rather than only the older Khmer Rouge-era contamination.

The three-decade picture, and why the trend line is real

This isn’t a one-off surge. Since 1992, Cambodia’s mine action programme has mobilised roughly $1 billion, about 30 percent from the Cambodian government and the rest from international donors, the private sector, and philanthropy [S-850]. Over that period the country has cleared more than 3,500 square kilometres of contaminated land, destroyed over 1.2 million landmines, and removed more than 3 million items of unexploded ordnance [S-850]. The human toll has moved with it: annual mine casualties have fallen from more than 4,000 in the 1990s to fewer than 100 a year over the past decade [S-850]. Phnom Penh and 14 provinces have been formally declared mine-free [S-850]. Separately, China’s Lancang-Mekong cooperation project has cleared roughly 190 square kilometres and destroyed some 104,000 mines and ERW since 2018 alone, reaching over 1.4 million rural residents — a concrete, delivered figure worth noting against the more rhetorical China security-cooperation language this site examined in its June 26 Xi–Hun Sen piece. Nationally, of the land released since 1992, roughly 78 percent has gone to agriculture, 5 percent to infrastructure, and 17 percent to community use — which is the closest thing to a direct read on how demining feeds the rural land supply this site’s readers actually transact in.

The part that matters for 2030 — and for underwriting anything long-dated

Cambodia has already had its mine-clearance deadline extended twice; the 22nd Meeting of States Parties to the Anti-Personnel Mine Ban Convention granted a third extension, to December 31, 2030, for anti-personnel mines, with cluster munitions and other ERW pushed to a 2035 horizon under the National Mine Action Policy 2026-2035. Under that policy, roughly 550 square kilometres of known mine-affected land still needs clearing to hit the 2030 milestone — which requires an average clearance rate of about 112 square kilometres a year. Cambodia has averaged about 130 square kilometres a year over the past five years, so the officials running the programme call the 2030 target “within reach” — but explicitly conditional on sustained funding and technical support continuing at current levels. That conditionality is the honest version of the headline: the trend is favourable, not guaranteed, and it is a donor-and-budget-dependent trend, not a fixed schedule.

What “cleared” doesn’t tell you

This is where the property angle actually lives, and where enthusiasm about a big clearance number needs a check. Clearance and land-title status are answering two completely different questions, and a strong result on one says nothing about the other:

  • “Surveyed” is not “cleared.” CMAC’s own report distinguishes assessing a village (confirming and mapping the extent of contamination) from clearing it (physically removing the hazard). In the six intensified border provinces, survey teams had assessed 335 of 349 affected villages by mid-2026 — meaning 14 villages in exactly the provinces getting the most attention had not yet even reached the survey stage, let alone full clearance.
  • A province-level “prioritised” or “intensified” label is not a parcel-level certificate. The 1,455 hectares released for household return and the 154 hectares released for schools in H1 2026 are specific, documented releases. A given plot of agricultural or residential land elsewhere in the same province may or may not be on that list.
  • This year’s contamination in these six provinces is partly new, not just historical. Preah Vihear, Oddar Meanchey, Banteay Meanchey, Battambang, Pursat, and Koh Kong are being prioritised because Thailand’s 2025 strikes — which Cambodian officials say involved cluster munitions, chemical smoke munitions, aerial bombardment, and suicide drones — added fresh contamination on top of the country’s older Khmer Rouge-era and civil-war minefields. CMAC Director-General Heng Ratana’s own framing of the clearance effort ties it explicitly to the first anniversary of that attack, not only to the legacy landmine problem this site’s readers may already assume is the whole story. That matters for underwriting: the risk in these six provinces isn’t purely an ordnance-clearance question with a clean 2030 endpoint — it’s layered on top of an active, unresolved border dispute this site has covered in its Thailand border closure piece, where a ceasefire has held since December 27, 2025 but the underlying dispute has not been resolved and land crossings remain shut.
  • Clearance doesn’t touch title. A physically demined parcel in a rural border province is exactly the kind of land where soft title, unclear boundaries, and undocumented family or communal claims are already common — the risks this site’s land-title verification guide and due diligence checklist already treat as standard. Demining removes one hazard; it adds no title paperwork.

What to actually verify

For anyone evaluating land in Preah Vihear, Oddar Meanchey, Banteay Meanchey, Battambang, Pursat, Koh Kong, or any other historically mine-affected province:

  • Ask for the specific CMAC/CMAA clearance or land-release record for the parcel, not a general claim that the district or commune has been cleared. Cambodia’s mine action authorities maintain village- and parcel-level release records precisely because province-wide statements aren’t precise enough to transact on.
  • Check whether the parcel falls inside one of the six 2025-conflict- affected provinces, and if so, treat the ordnance-clearance timeline as entangled with the broader border dispute’s trajectory, not as an independent, purely administrative process.
  • Never treat clearance as a substitute for title diligence. Run the standard title, boundary, and counterparty checks regardless of clearance status — a demined plot with unresolved title is still an unresolved title.
  • For agricultural land specifically, ask what the parcel’s demining and land-release history implies about soil disturbance, remaining sub-surface risk at depth, and any restrictions attached to the release (some released land carries conditions tied to its original resettlement or infrastructure purpose).
  • Watch the 2030 target as a funding story, not a fixed date. If donor and government funding for mine action softens, the clearance rate — and the pace at which more border-province land becomes verifiably safe and transactable — softens with it.

The takeaway

Cambodia’s mine action programme is one of the country’s genuine, sustained institutional successes — a three-decade, billion-dollar effort that has cut annual mine casualties by more than 97 percent and cleared over 3,500 square kilometres of land, with 2026 on pace for another strong year. That progress is real and it is gradually unlocking more rural and border-province land for agriculture, housing, and infrastructure. But “cleared” is a specific, documented status that applies parcel by parcel, not a blanket reassurance that a province is now safe to transact in without checking further — and in the six provinces getting the most attention this year, the clearance effort is entangled with an active border dispute, not just a legacy landmine problem. Treat a demining record the way you’d treat any other single line on a due diligence checklist: necessary to verify, and no substitute for the rest of the checklist. None of this is legal advice; verify current clearance and title status with CMAC/CMAA and qualified local counsel before committing capital to land in any historically mine-affected province.

Frequently asked questions

How much of Cambodia is still contaminated by landmines?

Under the National Mine Action Policy 2026-2035, roughly 550 square kilometres of known mine-affected land remain to be cleared to hit the government's 2030 target — against a five-year average clearance rate of about 130 square kilometres a year. Cambodia has cleared over 3,540 square kilometres and destroyed more than 1.2 million landmines since 1992, but the residual area is concentrated in exactly the northern and western border provinces where rural and agricultural land is cheapest.

Does landmine clearance make land in Banteay Meanchey or Battambang safe to buy?

Clearance and title verification are different questions, and neither substitutes for the other. A parcel can be physically cleared of ordnance and still carry unresolved title, boundary, or use-status problems, and 'surveyed' isn't 'cleared' — CMAC's mid-2026 report had assessed 335 of 349 affected villages in the six intensified border provinces but hadn't finished clearing them all. Ask for the specific land-release record for the parcel, not a general claim the province has been prioritised.

Why were six border provinces suddenly prioritised for mine clearance in 2026?

Because they were freshly contaminated, not just historically so. Preah Vihear, Oddar Meanchey, Banteay Meanchey, Battambang, Pursat, and Koh Kong were hit in Thailand's 2025 strikes, which Cambodian officials say included cluster munitions and aerial bombardment layered on decades-old Khmer Rouge-era minefields. The 2026 clearance surge there is as much post-conflict remediation as legacy landmine work — why the border dispute, not just the ordnance, belongs in your risk assessment.
