The fall armyworm (FAW) keeps spreading to larger areas in countries in sub-Saharan Africa and becomes more destructive as it feeds on more crops and different parts of crops, increasingly growing an appetite for sorghum and millet, in addition to maize. The pest could spread to Northern Africa, Southern Europe and the Near East, warned the United Nations’ Food and Agriculture Organization (FAO). The organisation called for a massive scaling up of the fall armyworm campaign to train more than 500 000 farmers to manage the pest through Farmer Field Schools in sub-Saharan Africa.
“Fall armyworm infestation could leave 300 million people hungry in sub-Saharan Africa, having already infested maize and sorghum fields across 44 countries in an area of more than 22 million square kilometres – the combined area of the European Union, Australia and the United States,” said Bukar Tijani, FAO assistant director-general and regional representative for Africa. “We are particularly concerned about the disastrous impact the pest can have on countries already facing crises.”
To date, FAO has invested more than $9 million from its regular budget, and mobilized $12 million for its FAW programmes.
“Despite significant contributions from resource partners and governments, there is still a significant financial gap. While we commend contributions made by a wide range of resource partners, including from those African countries affected by the pest, there is a need to urgently fill a critical gap of $23 million to allow FAO to effectively support countries in addressing FAW challenges in 2018,” Tijani said.
“In 2017, FAO and partners built a solid line of defence against the pest,” Tijani said. “We have developed tools and put measures into place to tackle FAW – from training farmers and extension workers on how to apply local remedies such as collecting FAW larvae killed by naturally occurring pathogens, making a mixture of these pathogens and applying them on the infested crops to kill the pest, to equipping them with mobile apps so that they can recognize their new foe faster, and get immediate advice on how to manage it,” he added.
Building on the foundation
“Farmers trained in FAW management can now detect infestations earlier, are able to protect their crops better, and report less damage. The foundation is there. We just need to build on it – train over 500 000 farmers through 20 000 Farmers Field Schools across sub-Saharan Africa this year, support highly vulnerable countries where FAW is widespread and capacity to manage it is low, develop resources in local languages, and get governments up to speed on sustainable FAW measures, such as the use of bio-pesticides,” said Tijani.
FAO took immediate steps as soon as FAW was detected in Africa, including bringing together experts to share knowledge and experiences on sustainable FAW management; developing tools (farmers’ manual, mobile apps, web-platform, FAWRisk-Map) to build better warning, monitoring and response mechanisms; and supporting countries to mitigate pest damage, develop action plans and policies, and train extension workers and farmers.
In October 2017, FAO launched a five-year, $87 million fall armyworm programme. FAO’s fall armyworm response is supported by Belgium, Ireland, Japan and the United States of America.
More than 30 FAO-supported projects are rolled out across the continent to fight the pest. These include training 20 000 farmers and frontline extension workers to date as part of FAO’s Farmer Field Schools to recognize and report FAW infestations and use mechanical control, such as crushing the pest by hand, and applying bio-pesticides (neem, tobacco plants) and natural enemies (ants) to destroy the pest.
FAO also provides technical and policy advice on pesticide management and is involved in monitoring the use of chemical insecticides.
FAO warns against the heavy use of pesticides, which can be harmful for people, their environment and in the longer run, and recommends the use of bio-pesticides, including those based on bacteria, virus and fungus, which have been tested, developed, registered and used successfully in the Americas, where the pest has its origin.
These measures are in line with a sustainable, long-term management of fall armyworm as the pest cannot be eradicated, and African farmers need to learn to manage it without jeopardising their health and their environment.
FAO also developed a framework for partnership so that organisations joining the fight against FAW can follow guidelines on sustainable management of the pest when developing their projects and programmes. – FAO press release
