Ronny Sen pick up a grant of $10,000 (£7,702) for his project.
Sen won the prize for his work on the dusty coal town of Jharia in the eastern Indian
state of Jharkhand where underground fires have burned for more than a century.
"The underground fire in Jharia has been burning for more than a hundred years now.
People who inhabit that space have seen this since they were born.
So they are totally aware of it and it's very much a part of their life"
