The Myanmar Information Management Unit [UN MIMU] has released two maps which show townships with a known hazard due to the presence of antipersonnel mines, and the number of victims per township in 2010-2011.
This is the third map produced in a collaboration between MIMU in Yangon and Landmine & Cluster Munition Monitor, since 2009.

These maps document how many townships in the countries are known to have some level of mine pollution, and the number of known landmine victims from the townships in the 2010-2011 period. The maps do not provide precise details on the location of mined areas.

Mined areas are primarily concentrated on Myanmar’s borders with Thailand, but are a particular threat in eastern parts of the country as a result of decades of post-independence struggles for autonomy by ethnic minorities. Some 41 townships in Chin, Kachin, Karen (Kayin), Karenni (Kayah), Mon, Rakhine, and Shan states, as well as in Pegu (Bago) and Tenasserim (Tanintharyi) divisions suffer from some degree of mine contamination, primarily from antipersonnel mines. Karen (Kayin) state and Pegu (Bago) division are  suspected to contain the heaviest mine contamination and have the highest number of recorded victims.

No estimate exists of the extent of contamination, but the Monitor identified suspected hazardous areas (SHAs) in the following townships: every township in Karenni (Kayah) state; every township in Karen (Kayin) state; Mogaung, Momauk and Waingmaw townships of Kachin state; Bilin, Thanbyuzayat, Thaton, and Ye townships in Mon state; Kyaukkyi, Shwekyin, Tantabin and Taungoo townships in Pegu (Bago) division; Maungdaw township in Rakhine state; Hsihseng, Langkho, Lawksawk, Mongpan, Mongton, Monghpyak, Mawkmai, Namhsan, Nanhkan and Tachileik townships in Shan state; and Bokpyin, Dawei, Tanintharyi, Thayetchaung and Yebyu townships of  Tenasserim (Tanintharyi) division.

The total number of antipersonnel mine casualties in Myanmar/Burma remains unknown. No official information is available. The Monitor has identified 2,861 (219 killed, 2,445 injured, and 197 unknown) casualties between 1999 and the end of 2010 from available sources, however the actual number of casualties is known to be much higher. In 2010, there were at least 274 new mine/explosive remnants of war (ERW) casualties in Myanmar/Burma, based on state and independent media reports and information provided by NGOs and other organizations. Myanmar/Burma has remained one of the states in which the Monitor has documented high numbers of landmine casualties, and has ranked in the top five countries globally during the past five years. Assistance to people who suvive a landmine injury, and more generally persons with disabilities in Myanmar/Burma, continued to be marginal due to many years of neglect of healthcare services by the ruling authorities. No one has carried out an assessment of the needs of landmine survivors within the country and it does not have a victim assistance program or strategy.
