Darth Mykolaiovych Vader, who is dressed as the “Star Wars” character Darth Vader, poses for a picture as he dries his mask and helmet with a hairdryer in the bathroom of his apartments in Odessa, Ukraine, December 2, 2015. Darth Vader was bent on galactic domination, but his Ukrainian namesake enjoys more mundane pursuits: local politics, walking the family dog and a spot of embroidery. The Ukrainian citizen, who has changed his name to Darth Mykolaiovych Vader, ran for the post of local mayor in October, his political backers dressed as Stormtroopers. In his trademark black outfit, he is a regular sight around Odessa, a major port city on southern Ukraine's Black Sea coast. (Photo by Valentyn Ogirenko/Reuters)

A fish jumps over a net as a boy works in a fish farm at Htantapin township, outside Yangon, Myanmar February 18, 2016. One in five children in Myanmar aged 10-17 go to work instead of school, according to figures from a census report on employment published last month, and the opening up of the economy since 2011 has triggered a spike in demand for labour. Many children work in fish farming and processing. At Yangon's San Pya fish market, the country's largest, girls and boys as young as nine clean and process fish and unload boats and trucks during 12-hour overnight shifts.

Every year, the Consultative Group To Assist The Poor (or CGAP) hosts a photo contest asking entrants to submit photos based around the idea of microfinance.The purpose of the contest is to give amateur and professional photographers a chance to show the different ways that poor households manage their financial lives and make their lives better through financial inclusion.
