The challenges faced by farmers in the north, who account for most of what Nigeria eats, are affecting food prices and availability in the booming coastal south that’s home to the megacity of Lagos.More than 80% of Nigeria’s farmers are smallholder farmers, who account for 90% of the country’s annual agricultural production. Some work their fields with little more than a piece of roughly carved wood and their bare hands.

Farmers are facing low yields because the government has failed to develop infrastructure like dams to help mitigate the effects of climate change, said Daniel Obiora, national president of the All Farmers Association of Nigeria.There is little data available on the drying-up of smaller water bodies across the north. But farmers say the trend has been worsening.In Adamawa state, water scarcity caused by higher temperatures and changing rain patterns has affected over 1,250 hectares (3,088 acres) of farmland, disrupting food supply and livelihoods, Nigeria’s National Emergency Management Agency said last year.

Over-extraction of water and deforestation are other factors contributing to northern Nigeria’s drying rivers, according to Abdulsamad Isah, co-founder of local Extension Africa nonprofit that often works with farmers.Elsewhere in Sokoto state, Nasiru Bello tilled his farm to cultivate onions without assurance of a meaningful harvest. With nearby rivers and wells drying up, he has resorted to pumping groundwater for the farm that provides the sole income for his family of 26. But the cost of pumping amid soaring gas prices has become unbearable.

“The plants do not grow well as it did,” he said.

Nigeria is forecast to become the world’s third most populous nation by 2025, alongside the United States and after India and China.WASHINGTON (AP) — Organizers and the Kennedy Center have canceled a week’s worth of events celebrating LGBTQ+ rights for this summer’s World Pride festival in Washington, D.C., amid a shift in priorities and the ousting of leadership at one of the nation’s premier cultural institutions.

Multiple artists and producers involved in the center’s Tapestry of Pride schedule, which had been planned for June 5 to 8, told The Associated Press that their events had been quietly canceled or moved to other venues. And in the wake of the cancellations, Washington’s Capital Pride Alliance has disassociated itself from the Kennedy Center.“We are a resilient community, and we have found other avenues to celebrate,” said June Crenshaw, deputy director of the alliance. “We are finding another path to the celebration … but the fact that we have to maneuver in this way is disappointing.”

The Kennedy Center’s website still listswith a general description and a link to the World Pride site. There are no other details.
