CONAKRY, Guinea – The sun has set in one of the world’s poorest nations and as the floodlights come on at G’bessi International Airport, the parking lot begins filling with children.

The long stretch of pavement has the feel of a hushed library, each student sitting quietly, some moving their lips as their eyes traverse their French-language notes.

It’s exam season in Guinea, ranked 160th out of 177 countries on the United Nations’ development index, and schoolchildren flock to the airport every night because it’s among the only places where they’ll always find the lights on.

Groups of elementary and high school students begin heading to the airport at dusk, hoping to reserve a coveted spot under the oval light cast by one of a dozen lampposts in the parking lot. Some come from over an hour’s walk away.

The lot is teeming with girls and boys by the time Air France Flight 767 rounds the Gulf of Guinea at an hour-and-a-half before midnight. They hardly look up from their notes as the Boeing jet begins its spiraling descent over the dark city, or as the newly arrived passengers come out, shoving luggage carts over the cracked pavement.

“I used to study by candlelight at home but that hurt my eyes. So I prefer to come here. We’re used to it,” says 18-year-old Mohamed Sharif, who sat under the fluorescent beam memorizing notes on the terrain of Mongolia for the geography portion of his college entrance test.

Only about a fifth of Guinea’s 10 million people have access to electricity and even those that do experience frequent power cuts. With few families able to afford generators, students long ago discovered the airport.

Parents require girls to be chaperoned to the airport by an older brother or a trusted male friend. Even young children are allowed to stay out late under the fluorescent bulbs, so long as they return in groups.

“My parents don’t worry about me because they know I’m here to seek my future,” says 10-year-old Ali Mara, busy studying a diagram of the cephalothorax, the body of an insect.

They sit by age group with 7-, 8- and 9-year-olds on a curb in a traffic island and teenagers on the concrete pilings flanking the national and international terminals. There are few cars to disturb their studies.

Most are working on memorizing their notes, struggling to commit to memory entire paragraphs dictated by their teachers on the history of Marxism, or the unraveling of colonial Africa, or the geology of Siberia. Tests are largely feats of memorization, a relic from Guinea’s French colonial rulers.

According to U.N. data, the average Guinean consumes 89 kilowatt-hours per year _ the equivalent to keeping a 60-watt light bulb burning for two months _ while the typical American burns up about 158 times that much.

The students at the airport consider themselves lucky. Those living farther away study at gas stations and come home smelling of gasoline.

Others sit on the curbs outside the homes of affluent families, picking up the crumbs of light falling out of their illuminated living rooms.

“We have an edge because we live near the airport,” says 22-year-old Ismael Diallo, a university student.

It’s an edge in preparing for an exam in a country where unemployment is rampant, inflation has pushed the price of a large bag of rice to $30 and a typical government functionary earns around $60 a month.

The lack of electricity is “a geological scandal,” says Michael McGovern, a political anthropologist at Yale University, quoting a phrase first used by a colonial administrator to describe Guinea’s untapped natural wealth.

The Oregon-sized territory has rivers which if properly harnessed could electrify the region, McGovern says. It has gold, diamonds, iron and half the world’s reserves of bauxite, the raw material used to make aluminum.

For 23 years, the former French colony has been under the grip of Lansana Conte, a reclusive and temperamental army general who grabbed the presidency in a 1984 coup. Suffering from a heart ailment, Conte has repeatedly traveled abroad for medical treatment. Mass demonstrations earlier this year called for his resignation because of his health and the deteriorating economy, but he instead declared martial law.

Eighteen-year-old Ousman Conde admits that sitting on the concrete piling is not comfortable, but says passing his upcoming exam could open doors.

“It hurts,” he says, looking up from his notes on Karl Marx for the politics portion of the test. “But we prefer this hurt to the hurt of not doing well in our exams.”
