Humans have always been changing the earth’s surface, but the study of land use change has been greatly aided by satellite imaging since the 1970s. Professor Eric Lambin started his career working with satellite images to examine patterns of land change, and emphasizes that understanding the patterns requires going into the field and talking to the farmers and locals using the land. He also discusses how globalization and international trade can drive land use change in unexpected ways. Finally, Professor Lambin explains the concept of potentially arable cropland (PAC) and the relevance of “peak land” in the context of the Anthropocene, especially for policy makers.

I don’t have enough information here. I’ll go back to school.” Continue reading
Jane Lubchenco, the former head of the US government’s National Oceanic and Atmospheric Administration (NOAA), discusses what it’s like being asked to join the president’s “science team,” the tremendous breadth of research covered by NOAA, and what it’s like sitting in an airplane flying through hurricane Sandy. Dr. Lubchenco also reflects on her work as a science communicator and the now “platinum standard” of open science communication she helped develop at NOAA.
