L'Inrap, the French National Institute for Preventive Archaeological Research, participated in the International Geography Festival (FIG) in Saint-Dié-des-Vosges, which took place from October 2 to 4, 2026. The festival, now in its thirty-seventh year, has long positioned Saint-Dié-des-Vosges as a hub for geographical discussion, bringing together experts and enthusiasts to explore how different regions and environments evolve over time. This year's edition centered on the theme of landscape, reflecting a broader understanding of how landscapes—whether natural, human-altered, or affected by climate change—shape and are shaped by human history and society. The concept of landscape, as explored by geographers, goes beyond simple descriptions of nature. It encompasses a range of factors, including ecological changes, cultural practices, and political decisions, making it a multifaceted subject that can be experienced through all the senses. Landscapes serve as both a challenge and a tool for societies, offering insights into past and present ways of life. Preventive archaeology, which involves studying and recording archaeological sites before they are disturbed by construction or development, plays a crucial role in this discussion. These studies help uncover the layers of history embedded in the land, revealing how past human activities have left lasting imprints on the environment. One of the highlights of the festival was a conference by Erwan Bergot, responsible for archaeological research at Inrap, titled Traces of the Landscapes of the Great War. In his talk, Bergot discussed how preventive archaeology helps decode the material remnants of World War I, which still influence the current landscape. More than a century after the war, the marks of battles, military infrastructure, and post-war reconstruction continue to shape the terrain, offering valuable historical insights. This work is essential for understanding the long-term impact of human conflict on the environment. During the festival, a round table discussion, moderated by Pascal Ratier of Inrap, brought together archaeologists Louis Deweyer, Jeremy Gracio, and Agnès Charignon. They discussed how archaeologists reconstruct past landscapes, using examples from excavations in the Vosges region and other locations. By studying the remains of Paleolithic, ancient, medieval, and modern landscapes, researchers gain a deeper understanding of how past societies interacted with their surroundings. These reconstructions are vital for piecing together the complex relationship between human history and the natural world.
