Kangaroos and tanks: histories of militarized landscapes in Australia

Military operations can have repercussions for environments and landscapes a long way from the battlefields. In the case of Australia most military action during the 20th century happened far from its shores, apart from the incidental bombing by the Japanese of Darwin and a few other northern coastal towns during World War II. It is therefore surprising that an Australian historian, Ben Wilkie, Honorary Research Fellow in Australian Studies at Deakin University, researches the environmental histories of military conflict. This edition of the podcast explores some of these histories of militarized landscapes in Australia, and the evolution of Australian Defence Force environmental policies in the twentieth century with Ben Wilkie.

The watery ally: military inundations in Dutch history

For centuries, the Dutch have fought against their arch-enemy: water. But, during the Dutch War of Independence in the 16th and 17th centuries, the Dutch found an ally in their arch enemy. Their struggle against Spain seemed almost hopeless because the rebels were facing the best trained, supplied and funded European army of that era. As the underdog, they turned to water and used it as a weapon against the Spanish by planning and carrying out a number military inundations, intentionally flooding enormous swaths of land to stop or even defeat the enemy.

However, it is possible that during the Dutch Wars of Independence the province of Holland could have been permanently flooded and lost to the North Sea. The Spanish, hurt by the military inundations, hatched a secret plan that aimed at defeating the Dutch by turning their watery ally against them. Luckily, this plan was never carried out. While Holland survived, the Dutch constructed a line of fortifications and waterworks to facilitate military inundations, which became known as the Dutch Water Line. This militarization of the Dutch landscape had profound long term political, social and environmental consequences for the province and the region.

Episode 77 of the Exploring Environmental History podcast explores these social, political and environmental issues with Robert Tiegs, Adjunct Professor at Sheridan College in Ontario, Canada.

Water pollution in the Dutch Peat Colonies of Groningen, 1850-1980

In the mid-19th century the first potato starch and strawboard factories were established in the Groningen Peat Colonies (Veenkoloniën) in the Northern Netherlands. The number of factories increased to more than thirty by 1900. These industries brought jobs but also water pollution and stench caused by the release of thousands of cubic metres of waste water into the canals. For most of the 20th century pollution was not an issue but the industry believed that large amounts of useful substances were “wasted” by dumping it with the waste water into water courses. Experiments were set up to extract minerals and other substances for the production of fodder or fertiliser. None of these efforts resulted in solving the water pollution problem of the Groningen Peat Colonies. The pollution persisted until the latter quarter of the 20th century.

Episode 76 of Exploring Environmental History investigates the origins and extent of the water pollution in Groningen and why it took more than a century before the problem was solved. It highlights why the early experiments failed and the consequences of this for water quality in the province of Groningen.
