Exploring Environmental History is the podcast about human societies and the environment in the past. The periodic programmes feature interviews with people working in the field, reports on conferences and discussions about the use and methods of environmental history. You can listen to these audiocasts on your own computer simply by clicking on the "Listen to podcast " links in the list below. Podcast of previous years can be found in the annual archives. The following years are available: 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014.

The history of human civilization is closely linked to the exploitation of mineral resources. It is no coincidence that the periodization of prehistory and antiquity has been chosen according to the main metals in use: stone, bronze and iron. It shows the centrality of the exploitation and production of these mineral resources in human history. Since the Industrial Revolution metals have become global commodities, including tin. The importance of tin increased with the invention of canned food in the 19th century, and during the 20th century with the rise of the electronics industry. Both of these factors made tin a strategic resource not seen since the days that it was used in the production of bronze for weaponry.
A new edited book entitled Tin and Global Capitalism, 1850-2000: A History of the “Devil’s Metal”, explores the evolution of the global tin industry, from mining through the trade networks and the politics surrounding the strategic importance of tin. Interrogating the rhetoric of “strategic” raw materials is important in order to understand the social, political, and environmental effects of displacement of communities, environmental degradation and pollution, and ‘resource conflicts'.
This edition of the podcast explores these themes with the editors of Tin and Global Capitalism: Andrew Perchard, Senior Research Fellow in the Centre for Business in Society at Coventry University; Mats Ingulstad, Postdoctoral Fellow in the Department of Historical Studies, Norwegian University of Science and Technology (NTNU); and Espen Storli, Associate Professor in History at the NTNU.
The first people to settle in Australia, ancestors of present day Aboriginals, arrived in Australia about 50,000 years ago. They took advantage of the lower sea levels that were the norm throughout the last 100,000 years and were the result of a cooling global climate - part of the last ice age cycle. The first people who entered Australia encountered a cooler and drier continent than at present. From about 35,000 years ago global temperatures and water availability declined even further culminating in the Last Glacial Maximum (LGM), about 21,000 years ago. At this time, the Australian continent entered its driest and coolest period since modern humans colonized it. By 12,000 years ago the climate warmed rapidly, sea levels rose and climate began to ameliorate.
How did populations in Australia respond to these climate fluctuations? This episode of the podcast explores this question with Alan Williams, an archaeologist and graduate student in the Fenner School of Environment and Society at the Australian National University in Canberra, and an Aboriginal Heritage Team Leader at AHMS Pty Ltd. Alan’s research explores the responses and adaptations by Aboriginal people to climate change through time.
