"As of August 6, 49,845 people have been affected... and unfortunately we have recorded 22 deaths," Niger's minister for humanitarian action, Laouan Magadji, told public television late last night.
The floods have destroyed more than 3,000 homes and nearly 4,000 hectares of crops, the minister said.
Livestock has also been lost and drinking water supplies have been affected.
He said the government and charities have already distributed food, clothing and mosquito nets to those in need.
The deaths come after the United Nations aid chief raised alarm in June over a worsening food crisis in the Sahel region that has sent malnutrition rates skyrocketing to their worst level since 2012.
Nearly six million people are struggling to feed themselves in Burkina Faso, Chad, Mali, Mauritania, Niger, and Senegal, where 1.6 million children are suffering from severe malnutrition, said Mark Lowcock.
Niger has faced recurring floods in recent years, including in the desert areas of the north. In 2017, 56 people, including 20 in Niamey, died in floods that affected more than 206,000 people, according to the UN.
