Dakar:

The deadly heatwave that hit Africa’s Sahel region in early April would not have occurred without “human-induced” climate change, according to a study by the World Weather Attribution (WWA) group published Thursday.

The West African nations of Mali and Burkina Faso experienced an exceptional heatwave from April 1 until April 5, with soaring temperatures above 45 degrees Celsius triggering a large number of deaths.

Observations and climate models used by researchers at the WWA showed that “heatwaves with the magnitude observed in March and April 2024 in the region would have been impossible to occur without the global warming of 1.2C to date”, which they linked to “human-induced climate change”.

While periods of high temperatures are common in the Sahel at this time of year, the report said that the April heatwave would have been 1.4C cooler “if humans had not warmed the planet by burning fossil fuels”.

It added that the five days of extreme heat was a once-in-a-200-year event, but that “these trends will continue with future warming”.

The length and severity of the extreme heat led to an increase in the number of deaths and hospitalisations in the two countries, despite their populations being acclimatised to high temperatures, the WWA said.

A lack of data in the affected countries made it impossible to know the exact number of deaths, the WWA said, adding there were likely hundreds, if not thousands, of other heat-related casualties.

Countries in the Sahel region have had to contend with drought since the 1970s, as well as periods of intense rainfall from the 1990s.

The dwindling availability of water and pasture, compounded by the development of agricultural land, has disrupted the lives of pastoral populations and encouraged the emergence of armed groups that have extended their hold over vast swathes of territory in Mali, Burkina Faso and Niger.

The United States scrambled on March 17 to assess the future of its counterterrorism operations in the Sahel after Niger’s junta said it was ending its years-long military cooperation with Washington following a visit by top U.S. officials.

Top U.S. envoy Molly Phee returned to the capital, Niamey, this week to meet with senior government officials, accompanied by Marine Gen. Michael Langley, head of the U.S. military’s African Command. She had visited in December while acting Deputy Secretary of State Victoria Nuland travelled to the country in August.

The U.S. State Department said on March 17 in a post on X that talks were frank and that it was in touch with the junta. It wasn’t clear whether the U.S. has any leeway left to negotiate a deal to stay in the country.

Niger had been seen as one of the last nations in the restive region that Western nations could partner with to beat back growing jihadi insurgencies.

The U.S. and France had more than 2,500 military personnel in the region until recently, and together with other European countries had invested hundreds of millions of dollars in military assistance and training.

But that changed in July when mutinous soldiers ousted the country’s democratically elected president and months later asked French forces to leave.

Deteriorating relationships in Sahel

The U.S. military still had some 650 personnel working in Niger in December, according to a White House report to Congress. The Niger base is used for both manned and unmanned surveillance operations.

In the Sahel, the U.S. also supports ground troops, including accompanying them on missions. However, such accompanied missions have been scaled back since U.S. troops were killed in a joint operation in Niger in 2017.

It’s unclear what prompted the junta’s decision to suspend military ties. On Saturday, the junta’s spokesperson, Col. Maj. Amadou Abdramane, said U.S. flights over Niger’s territory in recent weeks were illegal. Meanwhile, Insa Garba Saidou, a local activist who assists Niger’s military rulers with their communications, criticized U.S. efforts to force the junta to pick between strategic partners.

“The American bases and civilian personnel cannot stay on Nigerien soil any longer,” he told The Associated Press.

After her trip in December, Ms. Phee, the top U.S. envoy, told reporters she had “good discussions” with junta leaders and called on them to set a timeline for elections in return for restoring military and aid ties. But she also said the U.S. had warned Niamey against forging closer ties with Russia.

Neighboring Mali and Burkina Faso, which have experienced two coups each since 2020, have turned to Moscow for security support. After the coup in Niger, the military also turned to the Russian mercenary group Wagner for help.

Cameron Hudson, who served with the Central Intelligence Agency and State Department in Africa, said the incident shows the diminution of U.S. leverage in the region and that Niger was angered by Washington’s attempt to pressure the junta to steer clear of Russia. “This is ironic since one mantra of the Biden Administration has been that Africans are free to choose their partners,” he said.

The U.S. delegation visit coincided with the start of Ramadan, a month of dawn-to-dusk fasting and intense prayer for Muslims. Niger’s junta leader, Gen. Abdourahmane Tchiani, refused to meet them. A U.S. press conference at the embassy in Niger was canceled.

The junta spokesperson, speaking on state television, said junta leaders met the U.S. delegation only out of courtesy and described their tone as condescending.

Aneliese Bernard, a former U.S. State Department official who specialized in African affairs and director of Strategic Stabilization Advisors, a risk advisory group, said the recent visit had failed and the U.S. needs to take a critical look at how it’s doing diplomacy not just in Niger but in the whole region.

“What’s going on in Niger and the Sahel cannot be looked at continuously in a vacuum as we always do,” she said. “The United States government tends to operate with blinders on. We can’t deny that our deteriorating relationships in other parts of the world: the Gulf, Israel and others, all have an influential impact on our bilateral relations in countries in West Africa.”
