We live in a new planetary epoch in which human activities have a significant global impact on the Earth’s ecosystems. In a recorded lecture, Diana Liverman, a Regents’ Professor in the University of Arizona School of Geography and Development, will present an exploration of how everyday food choices contribute to these changes and are in turn affected by them in an increasingly connected world.
Her talk at the Arizona Senior Academy begins at 3:30 p.m. Thursday (Jan. 29) and is part of the Academy’s encore presentation of a University of Arizona-sponsored series on food presented last fall at Tucson’s Fox Theater.
Humans are changing the climate, Liverman argues, and that climate change is going to have a whole range of impacts on our food system. It might mean we have shifts in the agricultural zones where we can grow things. Yields – the amount produced in a given area – will change. They will drop in many of the current agricultural areas, but warming may open up areas that are currently too cold, like Canada and Northern Europe. The availability of fish will change, too.
Her talk will address ways to ensure food security for all in a world where agriculture competes for land and water with cities, industry, and ecosystems; where climatic or economic upheaval in one corner of the world triggers food price rises in another; and where billions are hungry while others are overfed.
Liverman is Co-Director of the Institute of the Environment at the University of Arizona. Her work addresses challenges related to climate change, food security, and land use, among other environmental issues. She co-authored Food Security and Global Environmental Change and is among the 178 scientists, artists and scholars from the United States and Canada to receive a 2014 Guggenheim Fellowship Award.
