Fall Armyworm keeps spreading and becomes more destructive
27 June 2018, Rome - Fall Armyworm keeps spreading to larger areas within 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, 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) today. The agency called for a massive scaling up of the Fall Armyworm campaign to involve more than 500 000 farmers in sub-Saharan Africa.
"Fall Armyworm 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 Hans Dreyer, Director of FAO's Plant Production and Protection Division, on the sidelines of a resource partners' meeting in Rome.
To date, FAO has invested more than $9 million from its regular budget, and mobilized $12 million for its Fall Armyworm 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 effectively support countries in addressing Fall Armyworm challenges in 2018," said Gustavo Gonzalez, FAO's Director of the Resource Mobilization Division.
The pest first appeared in Africa in 2016, in West Africa. By today, it has quickly spread across sub-Saharan Africa, leaving now only 10 countries (mostly in northern Africa) not infested.
Smallholders, representing almost all of the tens of millions of maize farmers in sub-Saharan Africa, are worst affected by Fall Armyworm, and any further damage inflicted by the pest would have drastic consequences on their lives.
For example, if 20 percent of their annual maize yield was lost to Fall Armyworm, it would result in a deficit of 16 million tonnes of maize, worth nearly $5 billion.
Time for massive scaling up of Fall Armyworm campaign
"In 2017, FAO and partners built a solid line of defense against the pest," said Allan Hruska, FAO's Principal Technical Coordinator on the Fall Armyworm response.
"We have developed tools and put measures into place to tackle Fall Armyworm - from training farmers and extension workers on how to apply "local remedies" such as collecting Fall Armyworm 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 they can recognize their new foe faster, and get immediate advice on how to manage it," he said.
"Farmers trained in Fall Armyworm 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 Fall Armyworm is widespread and capacity to manage it is low, develop resources in local languages, and get governments up to speed on sustainable Fall Armyworm measures, such as the use of bio-pesticides," added Hruska.
At the meeting, resource partners highlighted FAO's coordination role in tackling Fall Armyworm, and expressed support for FAO's integrated pest management (IPM) approach, which means managing Fall Armyworm in an effective, and economically and environmentally sustainable way.
FAO's Fall Armyworm response to date
FAO took immediate steps as soon as FAW was detected in Africa, including: bringing together experts to share knowledge and experiences on sustainable Fall Armyworm management; developing tools (farmers' manual, mobile apps, web-platform) 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 Fall Armyworm infestations and use mechanical control, such as crushing of the pest by hand, and apply 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 with without jeopardising their health and their environment.
FAO also developed a framework for partnership so that organisations joining the fight against Fall Armyworm can follow guidelines on sustainable management of the pest when developing their projects and programmes.
