Grand Jury Prize
"Open waters, boundless waters" - Ludovic Lesven
Caption: This photo was taken in January 2022 during a scientific expedition to the Kerguelen archipelago in the far south of the Indian Ocean (Terres Australes et Antarctiques Françaises, TAAF). In a land untouched by human activity, you can contemplate water flowing without artificial obstacles (sealing, piping, dams, etc.), and without human pressure: an unspoilt landscape preserved from human folly, an ode to sobriety that should be found everywhere! [French Polar Institute, 1200 ENVIKER programme, 2022].
Biography: Ludovic Lesven is a lecturer and researcher in environmental chemistry at the University of Lille and LASIRE (UMR CNRS 8516). His work focuses on the origin, fate and toxicity of pollution in aquatic environments (lakes, rivers, groundwater, etc.).
Jury Prize
"Gouffre d'Enfer Dam" - Pierre Suchet
Caption: The Gouffre d'Enfer Dam at Rochetaillée (Saint-Étienne metropolitan area, Loire) was inaugurated in 1866. At the time, it was the largest dam in the world. Financed by the State, it was designed with 3 objectives in mind: 1) to supply drinking water to the city of Saint-Étienne, which was undergoing rapid population growth at the time; 2) to reduce flooding on the Furan; and 3) to ensure a minimum flow during low-water periods to supply hydraulic power to the numerous factories.

Biography: Pierre Suchet has been carrying out geo-photographic surveys of urban rivers in collaboration with researchers in the humanities since 2013. In 2022, his 10-year survey of the River Nièvre was the subject of a major open-air exhibition, shown in the main towns in the catchment area. In 2024, he exhibited his work on 4 rivers (Furan, Nièvre, Lez, Yzeron) at the Maison de l'Architecture in Lyon.
People's Choice Prize
"Kaw-habitation" - Marie Hastaran
Caption: In the Kaw marshes, between open water, marshy meadows and riverbanks that are the legacy of a long history of human activity, as evidenced by the remains of polders, rosewood extraction and slash-and-burn agriculture, water is the major structuring element. This hydrosystem, formed by a coastal depression and the Kaw river, is now used for extensive zebu farming and is protected for its biological value at national and international level. Photo taken in French Guiana, July 2022
Biography: Marie Hastaran is a graduate of ISTOM, an international engineering school specialising in agri-development. She did her end-of-studies work placement in French Guiana in an urban planning consultancy. Her engineering dissertation focused on the management of wetlands in French Guiana as part of local urban planning. Today, Marie works for the Aubrac Regional Nature Park as a project manager for "Aquatic Environments".
