Behind every farmer dealing with a crop pest is a scientist who has supported them by developing better seeds, crop protection methods and apps to identify weeds
A perfect storm of conditions led to the locust attack currently tearing through East Africa and Pakistan, where countries are deploying pesticides, military personnel and even ducks.
The UN's Food and Agriculture Organisation (FAO) has given the ultimatum of March to bring Africa's desert locust outbreak under control, calling for US$76 million to fund insecticide spraying.
But the ongoing outbreak is only the latest example of the devastation that crop pests can cause - there are tens of thousands more that farmers have to contend with, from diseases and fungi to weeds and insects.
And with such a variety of threats to harvests and yields, there is no silver bullet to protect against losses and damage. Rather, an integrated approach is needed that incorporates all available tools in the toolbox, from better forecasting and monitoring technologies to the controlled spraying of crops with biocontrol products, all supported by stronger partnerships.
Smallholder farmers are on the frontline when a pest outbreak takes hold. A small swarm of desert locusts can eat the equivalent food of 35,000 people per day, for example, while crop losses resulting from the spread of fall armyworm across sub-Saharan Africa are estimated to cost up to $6.1 billion a year.
Yet while their livelihoods are most at risk, smallholders can also play a significant part in tackling crop pests like the desert locust.
By giving farmers access to better surveillance technology that enables them to monitor pests and forecast potential outbreaks, infestations can be tracked and managed effectively.
A project in Bangladesh that helps farmers to deal with fall armyworm is one example of how this can be done effectively. Led by the International Maize and Wheat Improvement Center (CIMMYT), the initiative has trained hundreds of farmers and extension agents in identifying, monitoring and tackling infestations using combined approaches.
Yet effective pest management is not the responsibility of farmers alone - nor does it begin in the field. Behind every farmer dealing with a crop pest is a scientist who has supported them by developing better seeds, crop protection methods and scouting apps to identify weeds.
Using either conventional breeding or genetic modification, scientists can develop seeds that produce pest-resistant crops, for example.
CGIAR researchers from the International Center for Tropical Agriculture (CIAT) developed and released a modified cassava variety in Colombia, bred to be resistant against high whitefly, which outperformed regional varieties without the need for pesticides.
The International Institute of Tropical Agriculture (IITA) has also developed maize varieties resistant to the stem borer insect for use in West and Central Africa.
And last year, the Nigerian Biosafety Management Agency approved the commercial release of genetically modified cowpea to farmers - a variety resistant to the maruca pod borer, a type of insect.
Better seeds and crop protection products are vital - but we need to do still more.
Some biocontrol pesticides such as Green Muscle and Novacrid have been highly effective in the past if used against locust hopper bands before they congregate into swarms. But they have limited impact once the swarms start to move as well as limited availability and regulatory approval, and a relatively short shelf-life.
Further research into crop protection methods will pave the way for new chemical and biological solutions, which can keep pest outbreaks under control - or prevent them altogether.
But we also need closer collaboration with governments, research institutions, universities, donors and investors, and - crucially - farmers to address the challenges of pest infestations, and lessen their impact on food systems.
Collaboration is central to IITA's Biorisk Management Facility (BIMAF), a partnership established around the need for better coordination between researchers, civil society, farming communities, and non-governmental, public and private organisations.
There is no single, superior way to fight and control agricultural pests like the desert locust - battling them on all fronts is our best hope. Of course, prevention is the ultimate goal, and it is achievable. But stopping an outbreak in its tracks requires a huge amount of coordination and sustained financial support.
We must work together to develop new crop protection methods and get them into the hands of those who need them the most. The current locust outbreak - and future pest infestations - will only be defeated with a united front.
