Entries were judged on impact, composition, originality and technical ability by a panel of seven judges.

Some images pose more questions than they answer, making you want to find out more about them

The overall winner and environmental photographer of the year is Uttam Kamati for his inspiring image ‘Watering Melon’. Kamati, an amateur photographer and filmmaker from India, likes to capture the work of humanitarian projects, transforming these endeavours into candid, touching scenes.

His winning image depicts a husband and wife watering watermelon saplings on the Teesta river bed in West Bengal, India.

'Watering Melon' by Uttam Kamati

“Some images immediately strike a chord. Some images linger in your mind and won’t go away. And some images pose more questions than they answer, making you want to find out more about them," says Dr David Haley from the Manchester Metropolitan University, who was one of the seven members of the judging panel.

"As these qualities become apparent in ‘Watering Melon’ by Uttam Kamati, the environmental significance of this image is revealed.”

‘Eden Restored - The Mesopotamian Marshes of Iraq’ by Esme Allen

Esme Allen has been awarded the Forestry Commission England exhibition award for her series of images depicting life on the marshes of southern Iraq and will now be invited to exhibit a solo show of her work at one of England’s public forests.

A fascinating account of the return of the people who lived there as well as the ecological resilience of the flora and fauna of this unique landscape

The marshes were drained during Saddam Hussein's reign, forcing their inhabitants to flee to neighbouring countries. They were not only home to the Marsh Arabs but also to a huge variety of birds and wildlife. After Saddam's removal from power, local people smashed part of the dam walls and the water once again covered the dry land; many of the Marsh Arabs have now returned to live in a traditional way on the water.

"Esme’s photographs of the Mesopotamian marshes of southern Iraq are a fascinating account of the return of the people who lived there as well as the ecological resilience of the flora and fauna of this unique landscape," says Ian Gambles, director of the Forestry Commission England and another member of the judging panel.

‘Families are living under the Bridge’ by Bhar Dipayan

Bhar Dipayan is the winner of the young environmental photographer of the year category for his thought-provoking image above.

‘Ren Kyst - Got a spare afternoon?' by Verity White

The winner of the environmental film of the year category goes to environmental and wildlife filmmaker Verity White. Her film was originally made to support a marine litter campaign in the Norwegian Arctic.

Entries for the 2015 award were of the highest standard ever

She teamed up with the Norwegian environmentalist Bo Eide to bring to light the issue of marine litter on the Norwegian coastline. It includes the first ever footage of plankton ingesting microplastics.

The Chartered Institute of Water and Environmental Management (CIWEM) created the environmental photographer of the year competition to enable filmmakers and photographers to share environmental and social issues with international audiences, and to enhance our understanding of the causes, consequences and solutions to climate change and social inequality.

"Entries for the 2015 award were of the highest standard ever,” says Nigel Hendley, interim chief executive of CIWEM.

'Enjoy' by Michael Theodoric

Michael’s image captures a thought-provoking view of Jakarta, one of the most densely populated cities on earth

The winner of the cityscape category is Michael Theodoric, who captured this arresting image of a man enjoying the view of Jakarta from his hotel room.

Janet Miller, Atkins’ cities director, says: “As our global population climbs towards an estimated 10 billion people by 2050 and our urban centres swell, the way we plan and future proof our cities has never
been more important.

"Michael’s image captures a thought-provoking view of Jakarta, one of the most densely populated cities on earth, and provides a reminder of the importance of designing our city spaces sustainably for current and future generations.”

In total, 111 works of outstanding photographic art will be on display at the Royal Geographical Society in London from 22 June - 10 July 2015, followed by a national tour of forest venues, supported by the Forestry Commission England.

The pictures are 111 reasons to work together and help move the world forward one step at a time

The exhibition can be seen at Grizedale Forest Visitor Centre, Cumbria from 18 July – 7 September 2015.

"At a time when we are pushing the boundaries of human knowledge with advances in robotics and digital engineering, disasters such as the savage earthquakes in Nepal remind us that we cannot ignore Mother Nature,” says Nick Roberts, Atkins' CEO UKE.

“We need to bring together people who can view problems from every angle and come up with practical solutions that will enrich lives. The pictures are 111 reasons to work together and help move the world forward one step at a time."
