Call for Submissions

We are assembling a session around lidar and long-term environmental change for AAG 2021 (April 7-11, 2021). Please see the description below. If you would like to participate, the paper abstract deadline is currently set for Thursday (11/19) and abstracts can be edited until February. Please e-mail your AAG pin to the organizers once your abstract is submitted. We look forward to your papers!

Session title: Lidar and Long-Term Environmental Change in the Maya Lowlands

Session abstract:
Remote sensing technologies combined with high-resolution environmental data enhance our understanding of past and present landscapes. In the past decade, lidar has revolutionized our ability to assess landscapes and, combined with proxy data and spatial modeling, can be used to understand changes in environments and landscapes. This session highlights the use of remote sensing technologies, specifically lidar, with multi-proxy data to evaluate long term environmental change in the neotropics of the Maya Lowlands. Session topics include human-environment interactions using stable isotopic data from speleothems to evaluate climate change, modern precipitation records and spatial modeling to evaluate the changes in water availability, soil studies to assess variability in agricultural practices, and archaeological features and radiocarbon assays to model demographic shifts. Understanding the impacts of long-term environmental change on past societies elucidates how similar processes may affect modern global communities.


Description

Remote sensing technologies combined with high-resolution environmental data enhance our understanding of past and present landscapes. In the past decade, lidar has revolutionized our ability to assess landscapes and, combined with proxy data and spatial modeling, can be used to understand changes in environments and landscapes. This session highlights the use of remote sensing technologies, specifically lidar, with multi-proxy data to evaluate long term environmental change in the Neotropics, with a focus on the Maya Lowlands. Paper topics include human-environment interactions using stable isotopic data from speleothems to evaluate climate change, modern precipitation records and spatial modeling to evaluate the changes in water availability, soil and vegetation studies to assess variability in agricultural practices, and archaeological features and radiocarbon assays to model demographic shifts. Understanding the impacts of long-term environmental change on past societies elucidates how similar processes may affect modern global communities.
