On Myanmar's mountainous frontier with India live the Naga, a group of tribes historically known as warriors who kept the heads of enemies they killed. In Myanmar, around 120,000 people live in the Naga Self-Administered Zone in Sagaing Division where they survive mainly by subsistence farming and hunting. Cultural practices are changing - for example, younger men now wear trousers rather than traditional loincloths - although many Naga communities remain impoverished and inaccessible by road. The Naga speak dozens of languages and many of those in Myanmar use Burmese as a lingua franca. REUTERS/Soe Zeya Tun (MYANMAR - Tags: AGRICULTURE SOCIETY FOOD TPX IMAGES OF THE DAY)

Workers set up handmade dynamite inside a ruby mine in Mogkok February 27, 2014. Mogok, also known as the Ruby Land, is home to the world-famous Myanmar ruby. Residents from Mogok and nearby areas used to mine rubies for generations, usually on a manageable scale with traditional manual methods, until it was restricted due to joint ventures between the ruling government and its close business associates about 20 years ago. Unscrupulous mining by joint ventures, using heavy machinery, has left the town with dumps and craters. According to official data compiled by the state-run Central Statistical Organisation, the total ruby production in the country was over 19 million kilograms in the 2012-2013 (April/March) fiscal year and over 43 million kilograms in the 2011-2012 fiscal year.

Miners from Aurelsa mining company prepare to place dynamite in a tunnel near Relave, a mining village at the province of Parinacochas in Ayacucho, February 20, 2014. Tucked between two desert ridges in southern Peru, Relave looks like any of the thousands of ramshackle mining towns that blight the landscape in the world's sixth-largest gold exporter. But Relave is also home to Aurelsa, one of the first small-scale mines in the world to produce gold certified and marketed as "ethical" as part of a scheme aimed at reducing the harmful impact of illegal mining in mineral-rich developing countries.
