Climate change is breeding the MILLIONS of locusts invading Africa with heavy rainfall and hotter weather making it ideal for the insect to reproduce
- Africa experienced heavy rainfall and warmer temperatures in 2019
- This created an ideal environment for locust to mate, causing an infestation
- Officials are using pesticides and conducting aerial spraying to kill them off
Locusts by the millions are nibbling their way across a large part of Africa in the worst outbreak some places have seen in 70 years – and experts are blaming climate change.
The country has experienced heavy rainfall and warmer temperatures over the past year that are favorable conditions for locust breeding and in this case the conditions have become ‘exceptional’, experts explain.
Even now rainfall continues in some parts of the vast region and the greenery that springs up keeps the locusts fueled.
Heavy rains in East Africa made 2019 one of the region´s wettest years on record, said Nairobi-based climate scientist Abubakr Salih Babiker.
He blamed rapidly warming waters in the Indian Ocean off Africa´s eastern coast, which also spawned an unusual number of strong tropical cyclones off Africa last year.
To help prevent and control outbreaks, authorities analyze satellite images, stockpile pesticides and conduct aerial spraying.

‘Countries are trying to prepare but this took them by surprise,’ Babiker said.
The further increase in locust swarms could last until June as favorable breeding conditions continue, IGAD has said.
But Babiker said it is hard to say for sure when this outbreak will be over.
‘This has become psychologically pressurizing,’ he said, delicately.
The locusts ‘reproduce rapidly and, if left unchecked, their current numbers could grow 500 times by June,’ the United Nations says
The locusts ‘reproduce rapidly and, if left unchecked, their current numbers could grow 500 times by June,’ the United Nations says.
An ‘extremely dangerous increase’ in locust swarm activity has been reported in Kenya, East Africa’s economic hub, regional authorities reported last week. One swarm measured 60 kilometers (37 miles) long by 40 kilometers (25 miles) wide in the country´s northeast, IGAD said.
Kenya has not seen a locust outbreak like this in 70 years, Rosanne Marchesich, emergency response leader with the U.N. Food and Agriculture Organization, said Wednesday.
‘It´s the worst that we´ve seen in Ethiopia and in Somalia in 25 years,’ she added, noting extensive damage to crops. Millions of people in both countries already cope with the constant risk of drought or flooding, as well as deadly unrest in Ethiopia and extremist attacks in Somalia.
Now South Sudan, struggling to emerge from a civil war, and Uganda are bracing for the locusts´ arrival.

‘Uganda has not had to deal with a locust infestation since the `60s so there is concern about the ability for experts on the ground to be able to deal with it without external support,’ Marchesich said. ‘And in a country like South Sudan, already 47% of the population is food insecure.’
This week Uganda´s prime minister told agriculture authorities that ‘this is an emergency and all agencies must be on the alert,’ the government-controlled New Vision newspaper reported.
The swarms of desert locusts hang like shimmering dark clouds on the horizon as they scour the countryside in what are already some of the world´s most vulnerable countries, including Somalia. Roughly the length of a finger, the whirring insects in huge numbers have destroyed hundreds of square kilometers (miles) of vegetation and forced people in some areas to bodily wade through them.
‘A typical desert locust swarm can contain up to 150 million locusts per square kilometer,’ the East African regional body, the Intergovernmental Authority on Development, has said. ‘Swarms migrate with the wind and can cover 100 to 150 kilometers (62 to 93 miles) in a day. An average swarm can destroy as much food crops in a day as is sufficient to feed 2,500 people.’
Alarm and exasperation mix with curiosity as people try to shoo the locusts away by shouting, waving pieces of clothing or banging on sheets of corrugated metal. In rural Kenya, men dashed along a path waving leafy branches at the insects and laughing in astonishment.

‘These things here, they came to us from Ethiopia and are destroying everything along the way including our farm,’ said Esther Ndanu in the Kenyan village of Ngomeni.
‘We want the government to move very quickly to bring the plane to spray them with the medicine that can kill them, otherwise they will destroy everything.’
‘I am seeing a catastrophe,’ local official Johnson Mutua Kanandu said.
Major locust outbreaks can be devastating.
One between 2003 and 2005 cost more than $500 million to control across 20 countries in northern Africa, the FAO has said. It caused more than $2.5 billion in harvest losses.
To help prevent and control outbreaks, authorities analyze satellite images, stockpile pesticides and conduct aerial spraying.
In Ethiopia, officials have said they deployed four small planes to help fight the invasion.
The U.N. on Wednesday allocated $10 million for aerial spraying, with humanitarian chief Mark Lowcock saying families across the region ‘now face the prospect of watching as their crops are destroyed before their eyes.’
