ASU's Global Locust Initiative connects international experts to combat the expensive crop damage the insects commit worldwide
During a plague year, locusts affect the livelihoods of one in 10 people and cover 20 percent of the earth’s land surfaces. In most of the world, they are one of the most destructive crop pests. From 2003–05, $450 million was spent to stop a desert locust plague in Africa that caused $2.5 billion in crop damage.
But an issue that size inevitably attracts the brightest problem-solvers.
Representatives from 12 countries gathered at Arizona State University this week for the inaugural meeting of the Global Locust Initiative, a new research and action program designed to help scientists, governments, agribusiness workers and farmers cope with locust plagues.
The initiative, a unit of the Julie Ann Wrigley Global Institute of Sustainability, combines lab science, fieldwork and data modeling to help reduce locust outbreaks and the effects of plagues.
The goal? The well-being of farm communities and global sustainability. It’s based on three pillars: facilitating research, creating a global network and developing on-the-ground solutions with local stakeholders.
“It’s a challenge all continents except Antarctica are dealing with,” said founding director Arianne Cease, an assistant professor in the School of Sustainability who studies locusts.

A panel of experts from seven global regions kicked off the event.
Aliou Diongue from the World Food Programme in Senegal expressed his region's primary focus: the necessity of healthy crops.
“Food security is our utmost concern,” Diongue said.
In China, more than 1,000 species of grasshoppers and locusts pose a danger to crops including bamboo and rice. The nation struggles to control swarms like these, and Long Zhang of China Agricultural University was intent on prediction.
“How can we exactly forecast the big swarms?” he asked.
Australia deals with three native species, according to Chris Adriaansen, director of the Australian Plague Locust Commission, but in the U.S., “the North American locust is gone, essentially,” said Derek Woller of the USDA Animal and Plant Health Inspection Service. Woller noted that his unit deals with small outbreaks from 12 species.
The Global Locust Initiative is dedicated to fostering the knowledge transfer that will lead to new interventions that reduce the frequency and impacts of locust plagues.
