Archaeologists lend long-term perspective to food security and climate shock

17.02.2014
What role does pre-existing vulnerabilities play for people who experience a climate shock? Does it amplify the effects of the climate shock or is effect negligible?

Four Arizona State University archaeologists are looking into this as part of an international team examining how people can be most resilient to climate change when it comes to food security.

The group questioned whether vulnerability to food shortages prior to a climate shock – not the actual experience of the food shortage – is related to the scale of impact of that shock. They found a strong relationship.

The team used long-term archaeological and historical data from the North Atlantic Islands and the U.S. Southwest to form the basis of their understanding of changing dynamics in these areas. Each case in their study included information on evolving social, political and economic conditions over centuries, as well as climate data.

The extended timeframe and global scope allowed them to witness changes in the context of vulnerabilities and climate challenges on a wide scale.

"The pattern is so consistent across different regions of the world experiencing substantially different climate shocks, that the role of vulnerability cannot be ignored," said Margaret Nelson, an ASU President's Professor in the School of Human Evolution and Social Change.

Nelson made her comments today (Feb. 16) at the annual meeting of the American Association for the Advancement of Science in Chicago.

The other ASU archaeologists involved in the study are professors Keith Kintigh, Michelle Hegmon and Kate Spielmann, all of the School of Human Evolution and Social Change in the College of Liberal Arts and Sciences.

Their findings support the argument for focusing on reducing vulnerabilities to climate shocks to boost resilience, which will ultimately lead to fewer required recovery efforts when crises occur. Nelson said that most often disaster management does not address vulnerabilities prior to shocks but instead focuses on returning a system to its previous condition following a disaster.

"Exposures to climate challenges and other environmental risks are not the sole causes of disasters," she says. "People have unintentionally built vulnerabilities through decisions and actions in social, political and economic realms."

The project is funded by the National Science Foundation and Wenner Gren, and includes collaborators from such diverse institutions as the National Museum of Denmark and the North Atlantic Biocultural Organization.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
