Expert Urges Responsible Waste Management
An environmentalist, Dr
Bolanle Wahab, says responsible behaviour will build resilience of Lagos residents to flood disaster.
Wahab of the Department of Urban and Regional Planning, University of Ibadan, said this in Lagos during a City Resilience Workshop tagged: “Local Governments and Communities Working for a Climate Resilient Lagos.”
The workshop was organised by the Coastal Cities at Risk (CCaR-Lagos) led by University of Ibadan.
The CCaR is a five-year programme under the International Research Initiative on Adaptation to Climate Change (IRIACC).
The research project seeks to strengthen the capacity of four coastal megacities of Lagos, Bangkok, Manila and Vancouver to effectively respond to climate change and its impacts.
Wahab said that building resilience of Lagos to flooding would begin at the local government level.
According to him, recognition that risks and vulnerabilities for the various aspects of climate change in cities are shaped by local contexts and influenced by the actions and inactions of local communities.
He said that communities were key actors in building climate resilience based on their invaluable source of knowledge embedded in unique social, cultural, economic, political and physical realities.
The expert said that public and private agencies and community development associations must be in the vanguard and watchdogs in their respective localities to check unlawful actions.
“All of us must appreciate that we are stakeholders, we are contributors to flooding incidence in Lagos because solid waste is a driver of flooding.
“If we all engage in responsible waste management at household level by reuse and reducing the amount of waste generated and conversion of waste to gas, there will be less waste for the government to carry and the drains will be healthier.
“I do not usually buy fresh plastic bag whenever I go to the market to buy anything, I take the ones I have at home, if more people do this our environment will be better.
“The city will be resilient and healthier, not many houses will be flooded or collapse again and the livelihood of the people will be protected and secured.
“Our drains will be empty and storm water will be able to flow freely, but when we continue to choke the canal and drains with solid waste there will be flooding because rain will always fall,” Wahab said.
According to the expert, responsible behaviours in urban planning and development and in building sustainable infrastructure were crucial to resilient building in the state.
“If we must build bridges and culvert, they must be built to standard, built in anticipation of development that will take place in the next 10 years and the amount of groundwater that will pass through.
“We must learn to landscape. Most people do hard landscaping; they concrete the entire square metre of their compound, they do not plant grasses and percolation is inhibited.
“When we do this we are not creating a resilient community. We continue to be more vulnerable, exposed and we will keep having problems with flood.
“Agreed, Lagos is a low-lying coastal state and because of that we should not continue to exacerbate the situation by clogging the drains and erecting illegal structures,” he said.
He also advised residents to imbibe the culture of rain harvesting and conversion of collected rainwater to domestic use thereby reducing the volume of water fetched from well and borehole.
The Lead Researcher of CCaR, Dr Ibidun Adelekan, said that identifying and understanding the vulnerabilities of various communities would assist in addressing flood issues in the state.
Adelekan said that resilience could only be achieved through cumulative contribution of multiple interventions and actions overtime.
Dr Mayowa Fasona of the Department of Geography, University of Lagos, said that government should collaborate with the private sector in strengthening knowledge of climate change adaptation and disaster risk reduction for sustainable socio-economic development.
“Flooding will always occur in Lagos because of its coastal nature.
“As human, we have no power over nature, but we can change our attitude to reduce our exposure and vulnerabilities to its shocks and fast track our recovery systems,” Fasona said.

FG Urges Citizens To Prepare That Flood Will Affect 266 LGIn 33 States
This was disclosed in a keynote address by the Minister of Water Resources and Sanitation, Engr Joseph Utsev, at the AFO public presentation at the Presidential Banquet Hall, Abuja, organised by the Nigeria Hydrological Services Agency, NiHSA, with the theme ‘Smart Water Resources Management: Moving from Oil to Water-Based Economy’.
Utsev acknowledged that early information saves lives, livelihoods, protects infrastructure, and reduces economic losses, saying that, as part of the Federal Government’s commitment to improving flood forecasts and preparedness, is the modernisation of the national hydrological monitoring networks.
The minister also said his ministry is strengthening collaboration with the Nigerian Meteorological Agency, NiMet, to ensure better integration of weather and water information, as it is critical for delivering reliable forecasts that support farmers, disaster managers, urban planners, and other key sectors of the economy.
He said AFO is therefore not just a scientific report, it is a call to action by all in terms of preparation ahead of the flood season, as early information saves lives, livelihoods, protects infrastructure, and reduces economic losses.
However, the minister acknowledged that forecasts alone are not sufficient if the information does not translate into action at the community level, which he said his Ministry is working with other relevant government agencies to mitigate the impacts of flooding.
Meanwhile, the 2026 AFO presentation had in attendance President Bola Tinubu, represented by the Minister of Environment, Balarabe Lawal.
Others present were the federal ministries: Water Resources and Sanitation; Livestock Development, Environment and Women Affairs.
Others include the Speaker of the House of Representatives, State Governments, Service Chiefs, development partners and the media.
He said: “The 2026 flood forecast presented today provides us with the following general highlights: High Flood Risk: 14,118 communities in 266 Local Government Areas (LGAs) in 33 States and FCT fall within the high flood risk areas. The States are: Abia, Adamawa, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, Enugu, Gombe, Imo, Jigawa, Kaduna, Kano, Kebbi, Kogi, Kwara, Lagos, Nasarawa, Niger, Ogun, Ondo, Osun, Oyo, Plateau, Rivers, Sokoto, Taraba, Yobe, Zamfara and the FCT.
“Moderate Flood Risk: 15,597 Communities in 405 LGAs, 35 states except Ekiti State, will experience moderate flood risk.
“Low Flood Risk: Incidences of minimal flood is expected in 923 communities in 77 LGAs in 24 States. The States are Adamawa, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, Jigawa, Kaduna, Kano, Kebbi, Kogi, Nasarawa, Niger, Ogun, Ondo, Osun, Oyo, Sokoto, Taraba and Zamfara.
“Flash and Urban Flooding: Flash and urban flooding are projected in major cities in the country due to high rainfall intensities, low attention to management of water facilities including drainage systems, waterways and lack of flood resilience structures. Cities such as Abakaliki, Abeokuta, Abuja, Asaba, Benin City, Birnin–Kebbi, Calabar, Ibadan, Kaduna, Kano, Lagos, Makurdi, Nguru, Onitsha, Oshogbo, Port Harcourt, Sokoto, Warri and Yola, among others are to experience these categories of flood incidence.
“Coastal and Riverine Flooding: Bayelsa, Cross River, Delta, Lagos, Ogun, Rivers and Ondo are to experience coastal flooding due to rise in sea level and tidal surge and this would impact on fishing, wildlife habitation and river navigation.”
He also emphasised that, “As we transition toward a water-based economy, we must recognize that water security is national security. Effective water governance will play a critical role in ensuring food security, supporting economic diversification, and improving the overall well-being of our citizens.”
However, the Minister called on State andand Local Governments including communities to start preparation to mitigate the impacts of the predicted flood.
“I therefore call on state governments, local authorities, disaster management agencies, farmers, and community leaders to carefully study the findings and advisories contained in this document and take the necessary steps to prepare for the coming flood season.
“Furthermore, we are encouraging state governments to integrate flood risk considerations into land-use planning, urban development, and infrastructure design.
“Floodplains must be properly managed, drainage systems must be improved, and communities must be empowered to adapt to changing climate conditions.
“Preparedness remains the most effective strategy for reducing flood risks. When we plan ahead, we protect lives, safeguard infrastructure, and preserve economic gains. Let us commit to building a safer, more resilient and more water-secure nation.”
Earlier, the Director General/Chief Executive Officer, Nigeria Hydrological Services Agency, Umar Ibrahim Mohammed, NiHSA, said the 2026 AFO aligns with the Renewed Hope Agenda in terms of economic diversification, infrastructure development, climate resilience, food security and sustainable water management.
Mohammed also explained that, “The AFO has evolved into an important national planning instrument that provides early scientific prediction of flood risks in the country, evidence-based guide for decision-makers and platform for emergency coordination among stakeholders.
“In producing this year’s forecast, the Agency undertook a comprehensive and data-driven process to provide tailored information for high-risk flood zones and flash floods in urban cities and towns.
“Building on the success achieved through AFO publications, we have upgraded from reporting flood forecast to Flood Risk Intelligence Architecture and from the traditional modelling to Hybrid AI-Integrated Modelling system to improve forecast reliability, reduce false alarms and improve the lead time accuracy.
“Not these alone, the modelling for the 2026 forecast have been conducted in-house. This marks a strategic shift toward enhancing capacity building, manpower development and institutional resilience.”
