continues to be a hazard, with poisonous gas filled munitions still a problem. UXO does not always originate from conflict; areas such as military training bases can also hold significant numbers, even after the area has been abandoned. Seventy-eight countries are contaminated by land mines, which kill or maim 15,000–20,000 people every year. Approximately 80% of casualties are civilian, with children being the most affected age group. An average estimate of 50% of deaths occur within hours of the blast. In recent years, mines have been used increasingly as weapons of terror; especially against local populations, such as in the Syrian civil war. In addition to the obvious danger of explosion, buried UXO can cause environmental contamination. In some heavily used military training areas, munitions-related chemicals such as explosives and

Risks and problems

Unexploded ordnance, no matter how old, may explode. It might seem that the dangers of UXO decrease over time, but this is not always the case. Corrosion and damages sustained on impact pose significant difficulties to defuse UXO safely and also make the consequences of defusion harder to predict. Mixed explosive agents might separate or migrate over time and leave contact explosives like
nitroglycerin Nitroglycerin (NG) (alternative spelling nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by ...
e at random places in the shell. Sometimes components of the original explosives, in the presence of moisture, can form new explosive compounds with the metals in the shells like picrates that can leave a shell highly explosive, even when it is defused and the detonator destroyed or removed. Even if unexploded ordnance does not explode, environmental pollutants are released as it degrades. The toxic compounds and heavy metals can contaminate water and soil over time. Recovery, particularly of deeply-buried projectiles, is difficult and hazardous—jarring may detonate the charge. Once uncovered, explosives can often be transported safely to a site where they can be destroyed; if this is not possible, they must be detonated on site which might require evacuation of the surrounding area. Unexploded ordnance dating as far back as the mid-19th century still poses a hazard worldwide, both in current and former combat areas and at military firing ranges. A major problem with unexploded ordnance is that over the years, the detonator and main charge deteriorate to such an extent that they frequently become more sensitive to disturbance and therefore more dangerous to handle. Construction works may disturb unsuspected unexploded bombs, which may then explode. Forest fires may be aggravated if buried ordnance explodes. Heat waves, causing the water level to drop severely, may increase the danger of immersed ordnance. There are countless examples of people tampering with unexploded ordnance that is many years old, often with fatal results. For this reason, it is universally recommended that unexploded ordnance should not be touched or handled by unqualified persons. Instead, the location should be reported to the local police so that

Effects of the North African campaign of World War II

During the fighting in North Africa between the Axis and Allied forces, much of North Africa was heavily mined to prevent military advances. During the conflict, in addition to the millions of mines that were placed, some of the millions of shells which were fired did not explode, and remain deadly to this day.

are all affected by this issue, with civilians being injured and killed every year. UXO also slows progress, with areas having to be demined before being developed.


Algeria

Algeria has been contaminated with large numbers of mines and UXO throughout several wars, starting from World War II. During the Algerian war for independence, French forces laid up to 10 million mines on the Morice and Challe lines, on the eastern and western sides of the country. In 2007, France officially handed over maps to Algerian authorities showing the locations of minefields. The lack of these maps had previously severely hampered Algerian demining efforts. Further mines were laid in the Algerian civil war by both warring parties, requiring further demining efforts. However, these mining operations were not on nearly as large a scale as French operations. By July 2016, Algeria reported that it had cleared all major minefields it had identified to clear. Thereafter, Algeria called on French authorities to provide compensation to the families of the 4000 people who are estimated to have been killed by mines, and thousands who have been left disabled from French ordnance.


Chad

Chad has been dealing with contamination issues stemming from its numerous conflicts between the 1960s and the 1980s. A significant portion of this contamination comes from the presence of anti-personnel mines, many of which are believed to have originated from Libyan sources during that period. As of 2020, estimates provided by the Mine Action Review indicated that approximately 10 square kilometers (or 3.9 square miles) of Chadian territory remained contaminated with these dangerous antipersonnel mines. Additionally, a smaller portion of unexploded ordnance (UXO) related to cluster munitions continues to affect some regions in the northern part of the country. In recent years, the ongoing jihadist insurgency led by
Boko Haram Boko Haram, officially known as Jama'at Ahl al-Sunna li al-Da'wa wa al-Jihad (), is a self-proclaimed jihadist militant group based in northeastern Nigeria and also active in Chad, Niger, northern Cameroon, and Mali. In 2016, the group spli ...
has further complicated the situation. According to the Chadian government, Boko Haram and similar insurgent groups are likely responsible for laying additional mines. These groups are also known for scavenging explosives from pre-existing UXO in order to manufacture

Effective mine clearance and UXO removal are essential not only to reduce the threat of accidental detonation, but also to limit the availability of materials that insurgents might use for their attacks.

that began in 2011, both government and opposition forces used mines. According to the Libyan mine action centre, 30–35,000 mines were laid; however, these were largely cleared after the downfall of the Gaddafi regime by ex-soldiers. With the downfall of the Gaddafi regime, in March 2011 large ammunition depots were left unatetended, and easily accessible by the civilian population, as well as soldiers and paramilitary forces. The government did not regain control of these depots, and munitions from the same depots were spread across the country. Several of the stores also exploded, spreading dangerous ordnance over a wide area. Many military vehicles were also destroyed in fighting all across the country, and these often contained ordnance in an unstable condition. With hostilities breaking out again in 2014, there were reports of both landmines and IEDs being laid by opposition groups, particularly in urban areas. This complicated clearance operations as these areas are often densely populated. In 2019, clashes between the

It was reported by the UN mine action service that booby traps were left in civilian homes with their only purpose being to cause civilian casualties. In January 2020, the UN estimated that Libya was contaminated by up to 20 million mines and pieces of UXO. The Russian paramilitary organisation Wagner which was operating in the area, also reportedly left munitions and mines in southern Tripoli.

On 24 May 2022, the Human Rights Watch wrote to the Russian foreign minister, asking to review their findings connecting with the Wagner group operations in laying mines in Tripoli, and clarify on the group's role in the conflict. The Russian authorities did not respond.


Mali

Major contamination of Mali with UXO stems from the resurgence of conflict in 2012 Mali. Mines and IEDs were laid more heavily in the north of the country. The situation deteriorated in 2019; however, the extent of the contamination is unknown, as there has been no clear mapping of the country's minefields.


Mauritania

Mine and UXO contamination stems from Mauritania's 1976–1978 war in the Western Sahara, while fighting against the Polisario front over the region. UXO is largely concentrated in the north of the country, around urban centres, where heavy fighting took place. Following the urbanisation of 70% of the country's

ic population, urban expansion has strayed into mine belts. As many of these nomads still follow pastoral practises, valuable livestock and people can stray into contact with mines. Despite this, people are unwilling to move due to the fact that Northern Mauritania is known as the best place to raise camels. It is also difficult to precisely mark mines, due to the fact that dunes can rapidly change their location. Although the country was declared mine free in 2018, Mauritania reported the discovery of previously unknown mined areas. As of 2023, an estimated of Mauritania was contaminated with mines.

All along the length of the wall (on the Eastern side) runs a minefield, sometimes claimed to be the world's longest continual minefield. During the 1975–1991 conflict, the Moroccan army used cluster munitions, and unexploded bomblets still kill and maim uneducated citizens to this day. Prior to the resumption of hostilities in November 2020, both the UN and the Moroccan army claimed to have destroyed tens of thousands of land mines, and cleared hundreds of square kilometres of land.

Despite conflict breaking out in 2011, by early 2023 it was reported that only just over of Sudanese land was contaminated with mines, and slightly more contaminated with UXO. In April 2023, heavy fighting broke out between the Sudanese Armed Forces (SAF), and the

Americas


Canada

After World War II, much unused ordnance in Canada was dumped along the country's eastern and western coasts at sites selected by the Canadian military. Other UXO in Canada is found on sites used by the Canadian military for operations, training and weapons tests. These sites are labeled under the "legacy sites" program created in 2005 to identify areas and quantify risk due to UXO. As of 2019, the Department of National Defence has confirmed 62 locations as legacy sites, with a further 774 sites in assessment. There has been controversy because some lands appropriated by the military during World War II were owned by

, such as that make up Camp Ipperwash in Ontario, which was given with the understanding that the land would be given back at the end of the war. These lands have required and still need extensive clean-up efforts due to the possible presence of UXO.


Colombia

During the long Colombian conflict that began around 1964, a large number of landmines were deployed in rural areas across Colombia. The landmines are homemade and were placed primarily during the last 25 years of the conflict, hindering rural development significantly. The rebel groups of Revolutionary Armed Forces of Colombia (FARC) and the smaller ELN are usually blamed for having placed the mines. All

Experts however, have estimated that it will take at least a decade due to the difficult terrain.


United States

Unlike many countries in Europe and Asia, the United States has not been subjected to significant aerial bombardment. Nevertheless, according to the Department of Defense, "millions of acres" of US territory may contain UXO, discarded military munitions (DMM) and munitions constituents (e.g., explosive compounds).Munitions Response Site Prioritization Protocol (MRSPP) Primer

A costly UXO recovery effort is under way. UXO on US military bases has caused problems for transferring and restoring Base Realignment and Closure (BRAC) land. The Environmental Protection Agency's efforts to commercialize former munitions testing grounds are complicated by UXO, making investments and development risky. The area around Fort St. Philip, Louisiana is also covered in UXO from the naval bombardment, and caution would be taken when visiting the ruins. UXO cleanup in the US involves over of land and 1,400 different sites. Estimated cleanup costs are tens of billions of dollars. It costs roughly $1,000 to demolish a UXO on site. Other costs include surveying and mapping, removing vegetation from the site, transportation, and personnel to manually detect UXOs with metal detectors.

Japan

Thousands of tons of UXO remains buried across Japan, particularly in Okinawa, where over 200,000 tons of ordnance were dropped during the final year of World War II. From 1945 until the end of the U.S. occupation of the island in 1972, the Japan Self-Defense Forces (JSDF) and the US military disposed of 5,500 tons of UXO. Over 30,000 UXO disposal operations have been conducted on Okinawa by the JSDF since 1972, and it is estimated it could take close to a century to dispose of the remaining unexploded munitions on the islands. No injuries or deaths have been reported as a result of UXO disposal, however.

Official records attribute at least 63 deaths and over 150 injuries to UXO explosions, though local reports suggest higher figures. In 2014, after significant public protests, the government declined to renew the military’s lease. The Indian Army subsequently initiated "Operation Falah" to clear the area of unexploded ordnance. Despite these efforts, sporadic explosions continue to pose risks, leading to ongoing demands for thorough demining and compensation for affected families.

, over half a million American bombing missions dropped more than 2 million tons of ordnance on Laos, most of it anti-personnel cluster bombs. Each cluster bomb shell contained hundreds of individual bomblets, "bombies", about the size of a tennis ball. An estimated 30% of these munitions did not detonate. Some 288 million cluster munitions and about 75 million unexploded bombs were left across Laos after the war ended. Estimates are that present rate of demining will require nearly 100 years to clear. Around 30% of Laos is considered heavily contaminated with UXOs and ten of the eighteen Laotian provinces have been described as "severely contaminated" with artillery and mortar shells, mines, rockets, grenades, and other devices from various countries of origin. These munitions pose a continuing obstacle to agriculture and a special threat to children, who are attracted by the toylike devices. From 1996 to 2009, more than 1 million items of UXO were destroyed, freeing up 23,000 hectares of land. Between 1999 and 2008, there were 2,184 casualties (including 834 deaths) from UXO incidents. Since the end of the conflict in 1975, unexploded ordnance, mostly from US bombing, has killed or injured over 25,000 people, half of them being children. UXOs continue to be a contentious issue as it has impeded infrastructure development and railway construction within the nation, including the Boten–Vientiane railway which required clearing thousands of hectares for UXO and shrapnel.


=Vietnam

= In Vietnam, 800,000 tons of landmines and unexploded ordnance is buried in the land and mountains. From 1975 to 2015, up to 100,000 people have been injured or killed by bombs left over from the second Indochina war. Nearly one-fifth of the land is contaminated by UXOs. At present, all 63 provinces and cities are contaminated with UXO and landmines. However, it is possible to prioritize demining for the Northern border provinces of Lang Son, Ha Giang and the six Central provinces of Nghe An, Ha Tinh, Quang Binh, Quang Tri, Thua Thien and Quang Ngai. Particularly in these 6 central provinces, up to 2010, there were 22,760 victims of landmines and UXO, of which 10,529 died and 12,231 were injured. One of the most heavily contaminated province, Quảng Trị, has seen at least 3500 deaths since the end of the war and ongoing efforts will require over a decade to clear. ''"The National Action Plan for the Prevention and Fighting of Unexploded Ordnance and Mines from 2010 to 2025"'' has been prepared and promulgated by the Vietnamese Government in April 2010.

munitions were dropped in towns and densely populated areas by Coalition forces, mostly in the first few weeks of the 2003 invasion of Iraq. An estimated 30% of the munitions failed to detonate on impact and small unexploded bombs are regularly found in and around homes in Iraq, frequently maiming or killing civilians and restricting land use. From 1991 to 2009, an estimated 8,000 people were killed or maimed by cluster bomblets alone, 2,000 of which were children. Land mines are another part of the UXO problem in Iraq as they litter large areas of farmland and many oil fields, severely affecting economic recovery and development. Reporting and monitoring is lacking in Iraq and no completely reliable survey and overview of the local threat levels exists. Useful statistics on injuries and deaths caused by UXO are also missing; only singular local reports exist.

or report directly to a mid-level administrative district. Germany's bomb squads are considered some of the busiest worldwide, deactivating a bomb every two weeks. The presence of UXO is an ongoing task. Areas that have been subjected to aircraft bombs and artillery shells or were known battle grounds are mapped. The reconnaissance photos of the allies taken after airstrikes may show UXO and are still used to this day for location. In mapped areas New road projects, demolition, new land developments require clearing with metal detectors by the authorities to get the permits. An estimated 5,500 UXOs from World War II are still uncovered each year in Germany, an average of 15 per day. Concentration is especially high in

As of September 10, 2023, the estimated number of civilians killed by mines and unexploded ordinance is 989, and this number will increase as the conflict continues and well after the conflict has ended. The Ukraine Mine Action Conference (UMAC2024) hosted by Switzerland and Ukraine aims to clear 10 million hectares (12.3 million acres) of land from land mines and UXO, this equates to roughly 10% of Ukraine's arable land. Before the invasion of Ukraine, agriculture made up some 11% of Ukraine's GDP, at the end of 2023 this figure had fallen to 7.4%. According to data presented in a Tony Blair Institute report, land mines are "suppressing Ukraine’s GDP by $11.2 billion (€10.27 billion) each year — equivalent to roughly 5.6% of GDP in 2021".

In international law

Protocol V of the Convention on Certain Conventional Weapons requires that when active hostilities have ended the parties must clear the areas under their control from "explosive remnants of war". Land mines are covered similarly by Protocol II. In addition to clearance obligations, Protocol V of the CCW requires parties to record information on the use and location of explosive ordnance and to provide this data to facilitate post-conflict clearance. It also encourages cooperation and assistance, allowing affected states to request international help with resources or expertise for ERW (Explosive Remnants of War) removal. Protocol V aims to reduce the long-term dangers posed by unexploded munitions to civilians and supports safer post-conflict recovery. The

(1977), parties to a conflict are required to take precautions to minimize harm to civilians, which includes managing the risks posed by UXO with an emphasis on preventing long-term civilian casualties.


Detection technology

Many weapons, including aerial bombs in particular, are discovered during construction work, after lying undetected for decades. Having failed to explode while resting undiscovered is no guarantee that a bomb will not explode when disturbed. Such discoveries are common in heavily bombed cities, without a serious enough threat to warrant systematic searching. Where there is known to be much unexploded ordnance, in cases of unexploded

ordnance a remote investigation is done by visual interpretation of available historical aerial photographs. Modern techniques can combine geophysical and survey methods with modern electromagnetic and magnetic detectors. This provides digital mapping of UXO contamination with the aim to better target subsequent excavations, reducing the cost of digging on every metallic contact and speeding the clearance process.
Magnetometer A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, ...
probes can detect UXO and provide geotechnical data before drilling or piling is carried out. In the U.S., the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) Department of Defense programs fund research into the detection and discrimination of UXO from scrap metal. Much of the cost of UXO removal comes from removing non-explosive items that the metal detectors have identified, so improved discrimination is critical. New techniques such as shape reconstruction from magnetic data and better de-noising techniques will reduce cleanup costs and enhance recovery. The Interstate Technology & Regulatory Council published a Geophysical Classification for Munitions Response guidance document in August 2015. UXO or UXBs (as they are called in some countries – unexploded bombs) are broadly classified into buried and unburied. The disposal team carries out reconnaissance of the area and determines the location of the ordnance. If is not buried it may be dug up carefully and disposed of. But if the bomb is buried it becomes a huge task. A team is formed to find the location of the bomb using metal detectors and then the earth is dug carefully.


Effects post-conflict

There are a variety of effects unexploded ordnance contamination has on post-conflict societies other than physical harm from detonation. Segments of society which are also negatively affected include

Industrialisation

UXO presence reduces farming communities’ ability to use industrial machinery due to higher likelihood of triggering a buried munition. As well as this, large scale

projects such as road, rail, dam, or bridge building which require heavy machinery are prevented due to the risk of setting off UXO. These two factors in turn reduce road building and therefore prevent other more remote communities from industrializing themselves.


Aid distribution

humanitarian aid Humanitarian aid is material and Humanitarian Logistics, logistic assistance, usually in the short-term, to people in need. Among the people in need are the homelessness, homeless, refugees, and victims of natural disasters, wars, and famines. Th ...
to rural or remote communities. Infrastructure for transportation is either impossible to develop, or preexisting infrastructure is difficult to demine.


Environmental effects

Demining procedures destroy topsoil. This causes increased erosion and can reduce the fertility of arable land. Munitions which are left over a long period of time degrade and eventually poison the soil or groundwater around them.


Education

The inhibition of necessary resources correlates with decreases in education. Injuries experienced by older members of the community take children away from classrooms to support a family's
