No fewer than 38 people have been killed and over 92,000 left homeless since June 2016 following devastating floods in Niger, the United Nations said.
The UN Office for the Coordination of Humanitarian Affairs said more than 26,000 livestock have been lost and more than 9,000 homes destroyed, citing government figures.
Meanwhile, authorities and NGOs have already given out aid to more than 50,000 people, with many of the homeless sheltering in schools and public buildings, the UN disclosed.
Agadez in the north and Tahoua to the west of Nigeri state are among the worst hit regions Despite being in the middle of the desert.
Niger is in the midst of its annual rainy season, having struggled to overcome a severe food crisis caused by drought.
