The HALO Trust (Hazardous Area Life-support Organization) is a humanitarian non-government organisation which primarily works to clear landmines and other explosive devices left behind by conflicts.

[10] It receives support from the US, UK and other governments around the world including Finland, Norway, Germany, Netherlands, Ireland and New Zealand.

[13] For more than 40 years, the population of Angola has been severely impacted by landmines and other explosive remnants of war (ERW), and is believed to still be one of the most mined countries in the world.

The clearance of minefields surrounding former Soviet military installations in Georgia is often complicated by significant quantities of waste and rubble.

HALO have mechanical mineclearance techniques to clear such sites using adapted civil engineering plant such as armoured excavators and front-loading shovels.

[23] The American NGO CNFA partnered with HALO to target the delivery of agricultural assistance to the farmers of Shida Kartli; this resulted in the region's largest ever apple and wheat harvests.

[25] In July 2011 Azerbaijani government blacklisted and banned the organization from Azerbaijan in protest for its mine clearing operation in disputed territory of Nagorno Karabakh.

The spokesperson for the de facto president of the Republic of Nagorno-Karabakh said that Ayvagyan's accusations do not represent the opinion of the government and that he was acting unilaterally.

[30][31] In May 2016 HALO announced that it had secured approval from the Israeli and Palestinian authorities as well as eight religious denominations to clear landmines from the site of the Baptism of Christ at Qasr al-Yahud (West Bank) / Al-Maghtas (Jordan).

[34] Despite a considerable reduction in casualty numbers over recent years, down from 875 in 2005[35] to 269 in 2008,[33] Cambodia's mine and ERW problem still represents a major impediment to the social and economic development of the country.

Recruiting, training and then deploying female and male deminers from the mine affected districts means that the landmine contaminated communities remain an integral component in the clearance process.

[37] Alongside clearance work HALO's survey teams have continued to systematically clarify the nature and magnitude of landmine contamination in Cambodia.

During the conflict, the country was subject to heavy aerial bombardment, resulting in the world's largest contamination from unexploded submunitions.

[41] HALO's survey, explosive ordnance disposal (EOD) and UXO clearance program is focused on the four most contaminated districts in Savannakhet Province.

HALO teams conduct manual and mechanical mine clearance alongside survey and explosive ordnance disposal (EOD).

In addition to the many items of UXO resulting from the conflict, the NATO bombing campaign in 1999 left unexploded cluster munitions in many locations across Kosovo.

[45] HALO maintained demining and battle area clearance operations between 2004 and 2006 and conducted a country-wide Community Liaison Survey in 2006 and 2007.

HALO currently has three teams and a total of 65 demining staff accredited and deployed clearing minefields and cluster munition strikes.

[49] The Colombian government formally invited HALO Trust in June 2009 to implement a large-scale civilian clearance program which is currently in the survey and assessment stages.

[49] HALO is the first civilian organisation to have a formal agreement and registration with the Colombian government and is currently surveying prioritised mined areas in preparation for humanitarian clearance operations.
