Captain François Roudaire (1836-1885) was convinced that a large inland sea could be created in the Sahara Desert across southeastern Algeria and southern Tunisia. The French military surveyor received funding from public and private sources in the 1870s to carry out feasibility studies on that region’s chotts or shebkas, seasonal salt lakes that are sometimes found below sea level. The centerpiece of his proposal was a long canal from Tunisia’s coast on the Gulf of Gabes to low-lying chotts in the interior. Once the Mediterranean began to flow into the desert, Roudaire believed, the Saharan climate would become cooler and the rate of precipitation in the region would increase. His announcement in the widely-read Parisian periodical Revue des deux Mondes in May 1874 that French engineers could build “une mer intérieure en Algérie” stirred up the imaginations of the capital’s political, social, and scientific elite.

For environmentally-minded historians, and particularly for those of us who study periods that suffer from a scarcity of written sources, archaeological data can be crucial. Excavations give insight into past material culture, providing information about past societies that is absent from the written record and offering tangible evidence of human interactions with the natural world. Yet, despite its many benefits, interpreting archaeological data isn’t easy, and shouldn’t be taken on lightly by those unfamiliar with the field. This summer, I had the opportunity to spend five weeks excavating at La Villa Romana Di Poggio Gramignano, a Roman villa-turned Late Antique infant cemetery in Umbria, Italy. Read more on the blog.

Georgetown Environmental History recently sat down with renowned Brazilian environmental historian José Augusto Pádua in Rio de Janeiro to have a conversation about fires and deforestation in the Brazilian Amazon. We asked him about the relationship between fire and deforestation, the history of deforestation in the Brazilian Amazon, and who is responsible for the recent surge in deforestation. Check out the video on our blog for his answers.

Environmental history (EH) is still in its infancy in academia, particularly on a global scale, when compared to other fields within the discipline of history. The practitioners of economic history, for example, are preparing for their 19th world gathering in Paris. The most recent World Congress of Environmental History (WCEH) was only the field's third, and it presented environmental historians from around the world with a great opportunity to meet fellow scholars in global EH. The conference also highlighted regional expansions and, more broadly, a global growth of an environmental way of doing history. Read more on the blog.

What the world knew about the environmental impact of China’s Three Gorges Dam during its early planning stages was largely thanks to the efforts of Chinese journalist Dai Qing. Three Gorges Dam is a giant dam on the Yangtze (Yangzi) River that the Chinese government erected during the 1990s and 2000s. It is the world’s largest hydroelectric dam in terms of installed capacity—it can produce an impressive 22,500 megawatts—and is one of the world’s most controversial dams because it had a gigantic social and environmental footprint.
