Flood alert: HEDA warns of rising national risks
Mr Suleiman Arigbabu, the Executive Secretary of Human and Environmental Development Agenda (HEDA Resource Centre), has warned of rising national risks due to the recent flood alert by the Nigeria Hydrological Services Agency (NIHSA)
Arigbabu gave the warning in an interview with the News Agency of Nigeria (NAN) on Sunday in Lagos.
NAN reports that NIHSA recently released its 2026 Annual Flood outlook, predicting flooding across many parts of the country at different periods.
Arigbabu said the forecast reflects historical trends, noting the agency’s predictions have recorded over 80 percent accuracy in recent years.
He attributed flooding to climate change and human activities, warning that the crisis will persist without urgent intervention.
Arigbabu said increased rainfall intensity and frequency are causing rivers to overflow, leading to flash floods and widespread inundation.
He identified poor drainage systems and weak flood management as major contributors to urban flooding.
He added that indiscriminate waste disposal continues to block drainage channels in cities such as Lagos and Port Harcourt.
Arigbabu decried the destruction of wetlands, noting their critical role in absorbing excess water and reducing flood impact.
He also highlighted deforestation as a factor, reducing the land’s natural ability to manage water flow.
According to him, failure to desilt dams and drainage systems has reduced their capacity, making even moderate rainfall cause flooding.
He noted that recurring floods over decades reflect neglect and inadequate investment in preventive infrastructure.
Arigbabu warned that flooding has the capacity to affect communities, businesses, and government projects across the country.
He said capital projects under the 2026 budget may face delays or damage due to heavy rains.
He added that flooding could displace residents, disrupt livelihoods, and increase the spread of diseases.
Arigbabu warned of rising food insecurity, limited healthcare access, and greater vulnerability among women and children.
The expert called for improved infrastructure, better environmental management, and responsible waste disposal.
He urged government and citizens to change attitudes to reduce flooding and its impacts.
