In 2021, Niger has been affected by subsequent floods due to heavy rains, causing several deaths and widespread damage nationwide.

Flooding was caused by heavy rainfall, which killed many people and destroyed thousands of homes across the country.

On August 19, flash floods slammed into Bukavu, the capital of South Kivu Province, killing one and leaving two people missing.

Flooding has affected 32,000 people in Nigeria's western, northern, and eastern regions, destroying hundreds of houses and crops and killing dozens.

[6] The 2016 floods in Niger were caused by wetland degradation, climate change, and excessive upstream dam outflow.

Due to the large number of Nigerian refugees, the international humanitarian aid in Niger was centered on the Diffa area.

[7] Doctors Without Borders and UNICEF, on the other hand, joined the local and federal government response to the floods, mainly in the most hit areas of Maradi, Tahoua, Agadez, and Zinder.

[8] In mid-July, Heavy rain in the Tahoua region's departments of Tchintabaraden and Abalak caused serious floods, impacting over 20,000 people and inflicting catastrophic damage to crops in the area.

[9] On August 26–27, continuous severe rains caused significant flooding, home devastation, and loss of personal possessions throughout Niger.

According to the National Crisis Task Force on Natural Disaster Floods, 17,389 dwellings and 7,836 hectares of agricultural land have been devastated, and over 30,000 animals have been lost.

According to the Ministry of Public Health, 247 cases of cholera, including four fatalities, have been reported in the department of Madarounfa in the southern Maradi area.

[16] The United Nations reported that more than 16,000 houses have been damaged, displacing tens of thousands of people, and an estimated 123,000 children have been directly affected by the floods.

[18] In 2020, flooding caused by heavy rains claimed 73 lives and sparked a humanitarian crisis with 2.2 million people needing assistance.

Local authorities in Maradi have provided food and non-food items to over 2,000 most vulnerable people in Oli Mamane Doutchi village, Bermo commune.

The floods have caused the Niger River, dams and dykes to burst and huge volumes of water to engulf people's homes, farms and other buildings without warning.

[25] In mid-June, heavy rainfall was experienced in the country, resulting in floods, causing widespread damage and casualties.

On July 31, the national authorities in Niger reported 35 people dead as a result of flooding and heavy rains in the country since the start of the rainy season.

[2] Rainy season in Niger starts from May until October, but most rains occur from June until August causing widespread flooding.

Wetland degradation is also a cause of the flooding since the ecology of the Niger River has been devastated by various land use changes.
