Casualties in 2017—details

The majority of casualties in Lao People’s Democratic Republic (PDR) in 2017, 78%, were caused by unexploded submunitions.This continued a change from 2016 when unexploded submunitions were recorded as the vast majority of casualties at 86% of the annual total, whereas submunition casualties represented less than half the total recorded casualties compared to ERW casualties in 2014 (47%) and 2015 (43%). Children made up 44% of all annual casualties recorded for 2017. The 19 incidents causing 41 casualties in 2017 occurred in eight provinces: Attapue, Bokeo, Champasak, Saravane, Savannakhet, Saysomboun, Sekong, and Xiengkhaung. Xiengkhaung recorded the most annual casualties in a province, with eight. 

By the end of 2017, the Monitor had identified at least 50,754 casualties, of which 29,554 were killed and 21,200 were injured.[2] The first phase of a nationwide casualty survey recording retrospective data was completed in 2008, which identified 50,136 mine/ERW casualties between 1964 and 2008. Of these, ERW caused the most casualties, followed by landmines, and then unexploded submunitions.[3] Between 2009 and 2017, a further 618 casualties were reported.[4]

[2] This total is based on the NRA National Survey of UXO Victims and Accidents Phase 1, which collected data on casualties between 1964 and 2008, and Monitor analysis of data from 2009 to 2017. However, the 2008 data is not complete, as information for that year depended on the date of the visit to the surveyed community and no data was collected after October 2008. See NRA, “National Survey of UXO Victims and Accidents Phase 1,” Vientiane, undated but 2009, pp. ix–x.
