Three weeks ago, Badamasi Mohammed embarked on a journey from Maradi, the second-largest city in Niger, leaving behind his wife and two children, headed towards Kano, a city located about 300km away (186 miles) in northwestern Nigeria.

However, since August 5, the 30-year-old freight truck driver has found himself stranded along with more than 20 other trucks at the Jibiya border post in Katsina, the state that connects Kano to Niger, the French-speaking neighboring country.

Nigerian border authorities have prevented him from re-entering his homeland due to ongoing sanctions imposed on Niger following a coup that took place on July 26. This coup resulted in the ousting of Mohammed Bazoum, who had been Niger's president since March 2021. In response to the coup, the conspirators also sealed the country's borders.

Over the past seven days, Mohammed's truck, parked at the border, has transformed into a makeshift bathroom, bedroom, walk-in closet, and overall multipurpose facility for him and his two assistants. To support him during this ordeal, his employer in Maradi had to send funds through currency exchange agents to the bank account of a point-of-sale attendant in Jibiya. This intermediary then provided cash to Mohammed.

The situation is beginning to take a toll on Mohammed, who serves as the primary provider for his family. He's unable to earn the average of 40,000 CFA ($67.25) he used to make per freight. His only solace is that he ensured there was enough food back home for his family to sustain themselves during his absence.

“I am not happy being away from my family, I am tired of being here,” Mohammed told Al Jazeera. “Each time I speak to my family, they always ask if people are being killed over here. They are not happy,” he said.

Landlocked Niger shares borders with seven African countries but the 1,600km-long (994-mile-long) border with Nigeria, Africa’s largest economy, is arguably its most important. More than a million people live along this stretch of land, and have shared commercial and cultural ties for centuries. Most of them are Hausa, the largest ethnic group in both countries.

The aftermath of the July 26 coup is now testing those ties as its effects spill across the borders from Niger, where life has also changed for everyone.

A flurry of sanctionsBazoum’s election was the first civilian-to-civilian transition in Niger since its independence in 1960 and in two years in office. His detention by members of his presidential guard and subsequent removal was the seventh coup across West and Central Africa in three years.

The coup also hurt the image of a country once seen as a reliable ally for the West in the Sahel, a region blighted by expansionist armed groups linked to al-Qaeda and ISIS (ISIL).

ECOWAS convened an emergency summit to determine an appropriate response.

The 15-member regional bloc swiftly imposed sanctions on Niger including the closure of land and air borders and giving a seven-day ultimatum to the coup leaders to reinstate Bazoum or face the potential use of force.

Multiple Western countries also cut funding to Niger, one of the largest by landmass – yet poorest – countries in the world, which relies on external aid for up to half of its budget.

Niger, the largest recipient of foreign in West Africa after Nigeria, received $1.8bn in aid in 2021 alone, according to figures from the Organization for Economic Co-operation and Development (OECD).

So far, the coup leaders have defied them and the bloc, rallying support in Niamey, the capital even on August 6, the day the ultimatum expired. A 21-person cabinet was also announced late on Wednesday by the coup leaders on the eve of another summit by ECOWAS.

At the grassroots, the impasse is already affecting Niger’s 25 million people, half of whom live below the poverty line earning less than $2.15 a day.

Nigeria also cut the power supply to its neighbour, which depends on it for as much as 70 percent of its electricity. And food prices, already on the rise because of complications in global supply since the Russian invasion of Ukraine, have risen yet again.

The post-coup sanctions and cessation of subsidies could hurt a country struggling with food security and one of the worst ratings on the human development indices in the world, experts said.

Mihidi Ameride works as a field officer at Projet Filets Sociaux (Safety Net Project), a project funded jointly by the World Bank and the Niger government.

His project caters to vulnerable and rural populations in 40 Nigerien communities through cash transfers and a cash-for-work (CFW) scheme. It also supports women artisans and keeps girls in school through scholarships.

Now that the World Bank has suspended aid to Niger, 66,000 households will be affected when the project ends, Ameride told Al Jazeera.

“There is great concern about the food security of populations subject to robbery, banditry and … personally, I’m affected, because my life depends on the sustainability of the project. It’s the only thing I do for a living,” Ameride said.

“I’m all for democracy and a coup d’état is not a good solution for an already poor country like Niger.”

The bloc also imposed sanctions on Guinea, Mali, and Burkina Faso, but lifted them later. The three nations have remained under military rule, and there has been a growing sense among international observers that sanctions were not working as a deterrent across the region.

“[The] junta will also be well aware that in neighbouring Mali and Burkina Faso, similar sanctions were also applied in the immediate aftermaths of coup d’etats but were later rescinded after these junta governments disclosed a transitional timetable and released all imprisoned politicians,” said Ryan Cummings, director of analysis at Johannesburg-based Risk Signal consultancy.

“It is tough to say that the sanctions are working [to end coups],” he added. “If anything, their application has emboldened the CNSP putschists who are undertaking mechanisms to entrench their rule, particularly in terms of creating a government with civilian inclusion so as to purchase this dispensation some legitimacy.”

Still, the effect of the sanctions could lead to significant inflationary pressures which will affect the country’s population, since Niger lacks the fiscal leeway to offset these cost-of-living pressures over the near-to-medium term.

‘No one is happy’Back at the borders between Nigeria and Niger, both countries are fully enforcing the “no entry- no exit” directive. Nigerian journalists were advised not to cross into Niger, as the relations between border officials of both countries had started to go sour as a result of the sanctions.

Commercial activities at the borders – including Jibiya, the busiest between both countries – have come to a halt with small business owners lamenting the adverse effects on their businesses. Nigeriens at the borders get most of their basic supplies from Nigeria; with zero movement, people in dire need are having to either crawl through the bushes or use a few unmanned crossings.

Cummings predicted that the Niger coup would likely play out in the same manner as other putschists in the West African region and called for diplomacy to avoid a conflict that could spread across the region and benefit armed non-state actors.

“To this effect, the junta will likely provide the international community, particularly ECOWAS, with some concessions. This may be the release of Bazoum – who is likely being held as a bargaining chip – and the provision of a transitional timetable which outlines the country’s return to constitutional rule,” he said.

Gbemisola Animasawun, associate professor at the Centre for Peace and Strategic Studies, at the University of Ilorin in Nigeria, said there is a need for the deadlock to be resolved because Niger was already in a “pitiable situation”.

However, there will be an overlapping effect for both Niger and Nigeria because the borders only exist in the minds of the state actors, he added.

“War is not an option whether directly or by proxy. Stakeholders must engage the coup leader and develop a transition plan,” Animasawun told Al Jazeera.

For Mohammed who is apolitical and has not voted in the last three Nigerien elections, the conflict cannot end soon enough. He is already planning to find a way through one of the smuggling routes into Maradi.

“I am not happy and no one is happy,” he said. “Only God knows the best.”
