Quantitative History Webinar -‪ From Forest to Farmland and Meadow to Metropolis: How did the environment shape human history, and how did humanity bring about the Anthropocene? [Jed O. Kaplan, HKU]
Did humans affect global climate before the Industrial Era? While this question is hotly debated, the co-evolution of humans and the natural environment since the last Ice Age had an undisputed role in influencing the development and present state of landscapes, many of which are highly valued today as economic, cultural, and ecological resources. Yet we still have a very incomplete picture of human-environment interactions over the last 21,000 years, both spatially and temporally, and how those interactions shaped the world in which we live today.

To address this problem, over the past decade Jed O. Kaplan of HKU Earth Sciences has worked on synthesizing demographic, technological, and economic development over preindustrial time, and creating a database of historical urbanization covering the last 8,000 years. These data are combined with computer simulation models to quantify the magnitude and timing of global anthropogenic land cover change in the late Pleistocene and preindustrial Holocene. His models are informed by paleoclimate scenarios from global climate models and simulate global land cover and human land use change, fire, soil erosion, and emissions of the greenhouse gases CO2 and methane (CH4). His results highlight the importance of the long histories of both climate change and human demographic, economic, and technological history on the development of continental-scale landscapes.

In this QH Webinar, Jed O. Kaplan will take the audience on a journey through time, starting with the way our distant hominin ancestors modified their environments to increase their chances of survival, and coming to the question of whether the planet itself can now survive the multitude of demands placed on it by modern society.
