Environmental Change & the Human Journey (GEOG20015)

The modern world is facing unprecedented anthropogenic environmental change.  Understanding the dynamic interplay between humans and our environment is of paramount importance if we are to successfully navigate this period of major environmental upheaval. Climate and environmental change have played a key role in shaping the biological, cultural, and geographic evolution of our species. What can an understanding of the past teach us about dealing with environmental change in the future?

This subject investigates the interrelationship between humans and their natural environments through time using evidence from physical and human geography, archaeology, palaeoanthropology, palaeoclimatology and palaeoecology. We will take a deep-time perspective, journeying from the emergence of humankind 6 million years ago to the present day. We will draw on case studies from around the word and across many different time periods, exploring how changing environments have influenced important transitions including the first migration of humans out of Africa, the emergence of symbolic behaviour, the beginning of agriculture and animal domestication, and resilience and collapse of complex societies. We will explore questions such as: Did environmental complexity shape brain development? Why did all other Homo species go extinct while Homo sapiens became dominant? Did humans play a role in the extinction of megafauna? Was the emergence of agriculture and domestication linked to changing environments? Is there a correlation between environmental change and the collapse of complex societies? How have human subsistence strategies and resource use impacted vegetation, animal species, soils and climate? How will anthropogenic climate change affect the future of our species?

The subject will include a 4-day fieldtrip to the World Heritage-nominated Budj Bim National Park in Victoria to learn about the long-term and continuing relationship that the Gunditjmara people have with their natural environment, and the ways in which they have both driven and adapted to environmental change. The field trip will take place in the mid-semester break.
