Fight against Fall Armyworm: Good Progress, More Efforts Needed

The Director-General of the Food and Agriculture Organization (FAO) of the United Nations, QU Dongyu, hailed progress in the fight against one of the most destructive pests jeopardizing food security across vast regions of the globe – while urging renewed drive and scaling up of efforts. 

Qu was speaking at the latest virtual meeting of the Steering Committee of the Global Action for Fall Armyworm (FAW) Control, attended by over 40 participants including FAO Members, international experts and key research partners. Fall armyworm – known in Latin form as frugiperda, or “lost fruit,” for its crop-wrecking potential – has dramatically spread eastwards from the Americas in the last five years. Having established itself in most of Africa, as well as large swaths of Asia, it has lately been reported in Australia and parts of Oceania. More than 70 countries are now affected; there are fears that the Mediterranean fringes of Europe could be next. 

Thriving in warmer climates, FAW primarily feeds on maize crops – but also on wheat, sorghum, millet, sugarcane, vegetables and cotton. The pest’s voracious appetite means that in many parts of the world, food, fuel and fibre are at severe risk. FAO estimates that FAW has contributed to worsening food security for 26 million people. While the bug cannot be eradicated, managing it is vital and possible through a coordinate approach. 

Demonstration countries 

In his address, the Director-General commended the steps taken to date: eight “demonstration” countries have been chosen as hubs for the Global Action, one for each geographical zone where the threat is most acute – China, India and the Philippines in Asia; and in Africa – Egypt, Burkina Faso, Cameroon, Kenya and Malawi. All have set up National FAW Task Forces, and are developing detailed work plans for monitoring, technology evaluation and capacity building. The demonstration countries have also served as links to “scale-up” countries from their region, with some 50 more attending coordination meetings to date. 

FAO’S Technical Cooperation Programme has been a “catalytic force to support a number of these efforts,” Qu told participants. The integrated pest management packages are based on the Organization’s guidelines. He added that “it is thanks to the excellent network among key stakeholders in the different countries that we have achieved these results together.” 

Down in the field 

Aside from the institutional level, FAO has been working to assist those whose livelihoods are most directly threatened. In 2020, despite limitations posed by the COVID-19 pandemic, nearly a million and a half African farmers were trained on scouting and monitoring the appearance and spread of FAW. They also learned about using bio-pesticides and pesticides, as well as nature-based solutions for FAW management. 

Those benefitting from this outreach include farmers such as Cyril Nzagumandore, in Rwanda’s Nyamagabe district. “Before, from this 10-hectare marshland, we used to harvest 5 to 6 tons,” he explains. “But in 2017, this dropped to 3.5 tons. We did our best to fight the worm, but had nothing to show for it. When the FAO project came, we understood more about FAW and the technologies it takes to fight it. The FAW mobile phone application I received allows me to collect and share information. Then the agronomist comes and inspects the field. Production has gone back up. Today, from our 10 hectares, we’re harvesting 7 tons.” 

Digitalizing the fight against FAW 

The app on Nzagumandore’s phone is part of the digital tools FAO has put forward to tackle the FAW challenge. Available in 29 languages, it analyses manually entered data and photos, and uses a mix of artificial and human intelligence, to detect the presence of the worm and offer guidance. Current proposals are to enhance the system with a predictive capacity: this would warn of impending invasions by combining more sophisticated data, ranging from meteorological patterns to insect reproduction cycles to the presence of other host plants in the vicinity. 

Overall, thousands of experts and technicians also received training from FAO last year in Africa and Asia – including on mass rearing of natural enemies of FAW, such as particular types of wasps. (Separately, China has included FAW monitoring and control in its own training programmes for nearly 4 million farmer technicians.) 

While lauding recent progress, the Director-General also stressed the need for more funding – adding that a Working Group on Resource Mobilization had been set up to that effect. The meeting agreed on the need to embed the fight against FAW within wider food security and nutrition strategies, in an effort to increase awareness and expand donor engagement. “There is still a lot of work ahead of us,” the FAO Director-General concluded, as he called for stronger, timely national and regional monitoring; early warning capacities; effective technology transfer; and stepped-up capacity development.
