Lindström, a professional based in Canada, triumphed over more than 10,000 entries to claim the £3,000 top prize with an image captured in Alberta.

Commenting on her winning shot, Lindström said: ‘It was an exceptionally warm day in July in southern Alberta when I came across this massive, pinkish smoke plume rising high towards the sky.

‘The big flames were thriving on the dry land and had me completely mesmerised in fear and awe.’

The competition was set up in 2007 by the Chartered Institution of Water and Environmental Management (CIWEM), whose chief executive Terry Fuller said of Hoyn’s image (above): ‘This image depicts the major humanitarian crises of our time, [with] each of the life vests representing a refugee and their journey.’
