Satellite Shows Agricultural Slowdown in Latin America

For the first time, satellite mapping of Latin America shows that the continent's agricultural expansion has waned in the wake of the global economic downturn, according to UBC research

"Nearly every agricultural region across Latin America slowed down in expansion from 2007 to 2013, compared to the previous six years," says Jordan Graesser, the study's lead author. Graesser is a visiting international student at UBC's Liu Institute for Global Issues and the Institute for Resources, Environment and Sustainability.

The study, recently published in Environmental Research Letters , involved the first large-scale mapping of changes in cropland and pastureland over more than a decade at the continental scale, usingsatellite imagery.

The slowdown is notable, given that agriculture in Latin America expanded faster over the past few decades compared to any other region on earth. The growth was fuelled by the continent's "Green Revolution" in the 1960s, where agricultural innovations, such as the development of new seeds, increased crop yields.

But the agricultural decline revealed by the study may not last. "Agriculture in Latin America is tied to global commodity prices," says Graesser, also a PhD student at McGill University's Department of Geography. "So if the global economy continues to recover, and if crop prices increase, there's likely going to be more expansion - which could impact biodiversity and boost carbon emissions."
