Navigating Nigeria's Flooding Crisis: Committing to Strategic Actions Amidst Environmental, Economic, and Social Challenges

The recent flooding in Maiduguri, Borno State, and the alert of flooding from the release of the Lagdo Dam, predicted to impact eleven states made me ponder once again on how as a country with an extensive governance structure, a national budget with a total expenditure of N27.5 trillion (equivalent to $36.7 billion), and the fourth highest GDP in Africa still grapples to address this critical development and economic issue. Flooding has become a recurrent crisis in Nigeria, exacerbating the country’s existing socio-economic challenges. According to data provided by the Centre for Research on Epidemiology of Disasters (CRED), from 1969 to 2022, flooding occurrences within the country have resulted in approximately 21,000 deaths, with the country recording at least US$17 billion in losses. Despite flooding being recurrent, Nigeria has faced increasingly severe flooding over the past few decades, with devastating consequences for life, property, and economic security. These floods have compounded the nation’s ongoing environmental, agricultural, and social challenges, further intensifying economic hardships and food insecurity. With the added pressure of climate change and socio-political issues such as internal displacement due to conflict, it is clear that Nigeria must take urgent, proactive steps to mitigate flood risks and develop long-term resilience.

While data shows that flooding in Nigeria has occurred almost on an annual basis, this article explores the historical impact of flooding in Nigeria from 1999 to 2024, analyzes the government’s current approaches to flood management, and critiques the role of international relief efforts. I also share recommendations on an actionable roadmap for addressing the country’s flooding crisis while taking into account broader social and environmental issues.

Flooding in Nigeria (1999–2024): A Persistent Crisis

Flooding in Nigeria has intensified in recent years, driven by a combination of factors including climate change, deforestation, urbanization, poor urban planning, and poor flood management infrastructure. The nation has experienced significant flooding almost every year since 1999, with notable events in 2012, 2018, 2019, 2020, and 2022.

• 2012 Nationwide Floods: Perhaps the most catastrophic flood in recent Nigerian history, the 2012 floods affected 30 states, leading to over 363 deaths, the displacement of 1.3 million people, and economic losses estimated at N2.6 trillion. The damage to infrastructure, agriculture, and housing was immense, as large swathes of farmland were submerged.
• 2018 Niger Delta Floods: This event primarily affected the southern regions, where heavy rainfall and poor drainage caused widespread destruction of homes and farms. About 100 people lost their lives, and thousands were displaced.
• 2019 and 2020 Floods: Similar patterns of seasonal flooding, worsened by climate variability, affected multiple states, with significant damage to agriculture and infrastructure.

Beyond these headline events, Nigeria faces a chronic cycle of seasonal floods that regularly destroy crops, homes, and infrastructure, exacerbating already dire economic conditions. According to the UNDP Flood Impact Recovery Mitigation Assessment Report (2023), floods have displaced millions, with devastating consequences for the nation's agricultural output and food security. The total estimated economic losses from flooding between 1999 and 2023 exceed $20 billion. The economic loss of the impending flooding from the Lagdo Dam opening in 2024 is estimated to be between $1.2 to $2.5 billion.

A question that comes to mind is - Why has Nigeria allowed flooding to continue to ravage our growing economy and hamper national development?

Government Response To Flooding

Successive Nigerian governments have attempted various measures to address the flood crisis. However, these responses have largely focused on post-disaster relief, rather than long-term preventive strategies.

For instance, after the 2012 floods, the government launched the Flood Relief and Rehabilitation Committee and released funds to assist affected states. While the immediate relief was appreciated, it did little to address the root causes of the crisis. In 2022, the government issued flood warnings and engaged in emergency response activities, but again, the focus was primarily on reactive measures, not preventive infrastructure. This year again, various federal government agencies alerted Nigerians of an impending flood that could impact between thirty percent to

One of the biggest missed opportunities has been the failure to complete the Dasin Hausa Dam project. Initially conceived to act as a buffer for the Lagdo Dam in Cameroon, the Dasin Hausa Dam remains incomplete. As a result, Nigeria remains vulnerable to water releases from Lagdo, as demonstrated by the recent flood alerts for 11 states in 2024 after Cameroon opened the dam’s spillways again.

Another significant failure has been the underfunding and poor maintenance of critical infrastructure like the Alau Dam. Reports reveal that despite over N400 million being budgeted for the Alau Dam in the past four years, little has been done to maintain the structure or address flood risks in Maiduguri. This typifies the systemic issues in flood management, where budget allocations are either insufficient or poorly utilized.

The national budget reflects Nigeria’s priorities, and unfortunately, flood prevention and environmental protection have been underfunded for years. Annual budgetary provisions across agencies like the Federal Ministry of Water Resources, NEMA, and state emergency agencies have been inconsistent, and when funds are allocated, they are often delayed or diverted to other uses. While NEMA and similar bodies focus on relief, there is limited coordination for long-term flood control infrastructure, early warning systems, and disaster preparedness.

In the 2023 and 2024 federal budget, allocations for environmental protection and flood control were modest. While the Federal Ministry of Water Resources received funding for projects, these did not cover comprehensive flood mitigation strategies such as dam maintenance, watershed management, or investment in flood-resilient infrastructure. At the state level, flood control budgets have also been minimal, with most states waiting until disasters strike to request federal assistance. Just to let you know, it makes it necessary to advocate and engage the government for funding these activities. I would also like to highlight the misappropriation of public funds. Recently, there have also been allegations of identified insertion of unrelated into federal MDA budgets. According to BudgIT, an estimated N2.2 trillion in the 2024 budget are indiscriminate insertions. A simple review shows a mismatch between budget line items and the mandate of MDAs. While this is a critical issue of concern, it is not the primary focus of this article.

There is a need for fiscal responsibility and social accountability from Nigeria's leadership, policymakers, and citizenry. It is quite ironic to know that the Dasin Hausa Dam which was proposed as a solution to buffer water and reduce flooding risks resulting from the release of the Lagdo Dam since its completion by Cameroon in 1982 is not yet a national priority.

Several low- and middle-income countries (LMICs) have implemented effective flood management strategies that provide valuable lessons for Nigeria. Bangladesh has made significant progress through the Bangladesh Delta Plan 2100 and community-based flood management, including early warning systems, flood shelters, and embankment construction. In contrast, Nigeria's early warning systems and community engagement are less developed, often resulting in a reactive response to floods.

Vietnam has focused on natural flood defenses, such as mangrove reforestation and flood-adapted housing, alongside modern infrastructure like reservoirs. Nigeria, on the other hand, has not fully embraced natural solutions, contributing to severe flood impacts. Kerala, India adopted a comprehensive flood zoning law and river basin management strategy after devastating floods in 2018. Nigeria, with weaker land-use enforcement, continues to face unplanned urban sprawl in flood-prone areas, exacerbating risks. Thailand improved its flood management after severe floods in 2011, constructing flood diversion canals and strengthening flood forecasting. Nigeria lacks comparable large-scale water management systems and zoning regulations.

Key lessons for Nigeria include investing in flood infrastructure, strengthening early warning systems, engaging communities in flood risk management, enforcing zoning laws, and adopting long-term climate resilience planning, as seen in these LMICs.

In Nigeria, systemic issues like corruption, misallocation of budgetary resources, and weak governance continue to impede effective flood management, exacerbating the country’s vulnerability to flooding.

Misallocation of Funds: Despite significant funding for disaster risk reduction, much of it is often mismanaged. After the 2012 floods that affected over 30 states, the government established a ?17.6 billion relief fund. However, allegations of misusing these funds emerged, with some state governments accused of diverting relief materials for personal gain, leaving many affected communities unsupported.

Lack of Accountability: While the Nigerian government allocates annual funds for flood management, many of these resources go untracked. A 2019 audit of the Ecological Fund Office revealed significant gaps in financial oversight and poor project management for flood mitigation, undermining the effectiveness of these initiatives.

Corruption in Infrastructure Projects: Flood management projects, such as dam and drainage system constructions, are frequently compromised by corruption. Contracts often go to incompetent contractors, leading to abandoned or poorly executed projects. For instance, the Kano River Irrigation Project, aimed at improving water management and reducing flooding, remains incomplete despite multiple funding cycles.

Ineffective Use of International Aid: Nigeria has received substantial international assistance for flood prevention, including support from the World Bank and UNDP. However, bureaucratic inefficiencies and resource misallocation have hampered the effectiveness of these efforts, preventing aid from reaching the most vulnerable communities.

These issues underscore the urgent need for fiscal responsibility in Nigeria's flood management. To effectively tackle flooding, the government must enhance financial oversight, improve budget transparency, and ensure that funds are used appropriately. This approach will help mitigate flood impacts, protect communities, and bolster climate resilience in the long run.

International Relief and Climate Finance: Relief With Sub-Optimal Prevention

Nigeria has benefitted from substantial international relief after major floods, but these funds are largely used for emergency relief rather than building resilience. For example, after the 2022 floods, international organizations provided over $70 million in humanitarian aid to support displaced communities, offering food, shelter, and healthcare. The World Bank also approved $500 million to improve flood resilience in Nigeria, although the focus has been more on recovery than on preventive measures. It is estimated from 1999 to 2024, Nigeria has received over $1 billion in international aid related to flood response and resilience-building efforts. These funds have been used to address both immediate humanitarian needs during flood disasters and long-term infrastructure development aimed at mitigating the impact of future floods.

Despite the volume of international investments in flood response and resilience-building efforts, Nigeria has not fully taken advantage of global climate finance to address the growing flood risks. The Green Climate Fund (GCF) and other climate financing mechanisms could be utilized to fund comprehensive flood management projects, but there has been little action from the government in this regard. Investing in climate finance yields both social and economic returns.

According to studies by the World Bank, every $1 invested in disaster risk reduction can save up to $4 in recovery and relief efforts. Additionally, investments in climate resilience can protect livelihoods, reduce displacement, and foster social stability. In northern Nigeria, where both conflict and climate risks are acute, climate finance could prevent future loss of life, reduce economic disruptions, and ease tensions over natural resources. By leveraging climate finance, Nigeria can address the root causes of flood vulnerability while promoting long-term economic growth. The return on these investments includes not only reduced disaster-related costs but also improved public health outcomes, better infrastructure, and enhanced agricultural productivity—all essential for building a more resilient future.

International support can be specifically channeled through climate finance mechanisms, technical assistance, knowledge sharing, and public-private partnerships with a structured roadmap. For instance,

1. Climate Finance Mechanisms: Organizations can help Nigeria access funds from sources like the Green Climate Fund (GCF), the Global Environment Facility (GEF), and the Adaptation Fund. These funds support projects aimed at improving climate resilience. For example, the GCF has financed Bangladesh’s climate-resilient infrastructure, while GEF funding helped restore mangroves in Vietnam, bolstering natural flood defenses.
2. Capacity Building and Technical Assistance: By providing training and resources, international organizations can strengthen local governance and improve flood management strategies. The UNDP’s capacity-building program in Bangladesh, which improved community preparedness, exemplifies this approach.
3. Knowledge Sharing: Facilitating the exchange of best practices among countries can enhance flood management. The World Bank's knowledge-sharing platform in Southeast Asia has enabled countries like Thailand to share successful strategies, improving regional policies.
4. Public-Private Partnerships: Promoting collaborations between governments and private sectors can lead to innovative solutions for flood risk management. Nigeria could benefit from initiatives like the Private Sector Initiative for Resilience, which has seen success in India.

Let me expand further on Public-private partnerships (PPPs). It is well documented that PPPs play a crucial role in disaster risk management, offering a pathway to leverage private sector expertise, resources, and innovation. Expanding on this, Nigeria can learn from successful collaborations both domestically and internationally. For instance, in Bangladesh, the private sector has worked closely with the government to establish flood shelters and early warning systems, reducing flood-related losses. Similarly, in Thailand, companies have invested in flood forecasting technologies and resilient infrastructure following the devastating floods of 2011. These partnerships have enhanced the capacity to prevent and manage floods, showcasing how the private sector can complement government efforts.

In Nigeria, there is potential for similar collaborations. Telecom companies could partner with the government to improve early warning systems by delivering timely flood alerts via mobile networks. Insurance firms could also work with local authorities to offer flood insurance, helping communities rebuild faster after disasters. Encouraging private investments in flood-resilient infrastructure, such as drainage systems and embankments, can further strengthen the country’s disaster preparedness. play a crucial role in disaster risk management, offering a pathway to leverage private sector expertise, resources, and innovation.

By utilizing these strategies, international organizations, local development actors and the private sector can significantly bolster Nigeria’s efforts to manage flood risks effectively, ensuring better preparedness and long-term climate resilience.

Committing to a Proactive and Sustainable Flood Management Action Plan

Nigeria needs to craft an intentional, comprehensive flood management strategy to effectively address this crisis. The government must shift from a reactive to a proactive approach. This comprehensive strategy should include:

• Investment in Dams: The completion of the Dasin Hausa Dam, upgrades of the Alau Dam, and others across the country are long overdue. The government must prioritize these projects with dedicated funding and a clear timeline for completion. While the cost may be quite significant the economic returns are rather appreciable. For instance, the Dasin Hausa Dam was expected to generate 300 megawatts of electricity and irrigate approximately 150,000 hectares of land across Adamawa, Taraba, and Benue states in the 1980s. However, with more advancement in hydropower and other sustainable energy solutions it would significantly enhance the power generation capacity which is strategic to addressing the current power supply situation in Nigeria. This will also address key aspects of food security and job creation.
• Leverage Climate Finance: Nigeria should aggressively pursue climate finance opportunities to fund flood resilience projects. The government can tap into the GCF to invest in flood control infrastructure, wetland restoration, and urban drainage systems. Additionally, a balanced combination of concessional loans, grants, climate adaptation funds, and carbon credits trading should be considered. Such funds should also be channeled into building resilient agricultural systems, in addition to infrastructure, to withstand the impacts of floods on food production.
• Strengthen Early Warning Systems, Evacuation Planning, and Epidemic Management: Early warning systems can save lives and reduce economic damage by providing timely alerts to vulnerable communities. Nigeria should invest in modern meteorological and flood forecasting technologies, ensuring that warning systems are integrated across local and national levels. Additionally, it is critical that evacuation plans are developed and they must be clear, actionable, and adequately resourced is essential to save lives and property. Flooding exacerbates public health challenges, leading to outbreaks of waterborne diseases such as cholera and malaria. Nigeria's health infrastructure must be prepared to deal with these flood-induced epidemics.
• Improve Coordination Between Agencies: Federal and state agencies need to work together under a unified flood management strategy. NEMA, the Federal Ministry of Water Resources, and other relevant bodies should collaborate on developing floodplain maps, maintaining dams, and coordinating rapid response efforts. Each agency should be empowered through appropriate budgetary provisions and performance monitoring to ensure efficiency in delivery of their mandate and the national budget.
• Public-Private Partnerships: Private sector involvement in flood management can help supplement government funding. This could involve companies investing in local infrastructure or supporting disaster preparedness programs in vulnerable areas.
• Tackle the Root Causes: Flooding is worsened by environmental degradation, such as deforestation and poor land use planning. Government should strengthen environmental protection laws, enforce zoning regulations, and encourage afforestation efforts to create natural buffers against floods.

The recommedation to tackle the pressing issue of flooding in Nigeria should be executed in a structured approach. It should first be categorized into short-term preventive measures and long-term resilience strategies.

Short-term Preventive Measures (0-2 years)

In the immediate future, Nigeria should focus on enhancing early warning systems by investing in advanced technology to provide real-time flood forecasts and alerts to communities. Simultaneously, clear emergency response protocols need to be established, outlining evacuation plans and resource distribution. Training programs for local leaders will empower communities to prepare effectively for floods.

Long-term Resilience Strategies (2-5 years)

Over the next few years, Nigeria should prioritize infrastructure development, constructing and upgrading flood defenses like levees and drainage systems. Stricter zoning and land-use planning will prevent construction in flood-prone areas, reducing future risks. Implementing natural flood management through reforestation and wetland restoration will bolster the country’s defenses against flooding.

Fiscal responsibility is crucial; transparent management of funds allocated for flood initiatives must be ensured through an established oversight committee. Moreover, seeking collaboration and funding from international organizations will provide additional resources and expertise to strengthen Nigeria's flood management efforts.

Implementation Framework

The implementation of these strategies can follow a structured timeline. In the first year, assessments of existing systems, community engagement, and all other identified initiatives should begin. It is critical that with a clearly define roadmap and assessment, the actual required cost can be identified and then engagements with funding organizations can be done. By year two, the early warning system project should be fully operational, alongside zoning regulations, and an oversight multi-agency committee that ensures accountability and monitors execution against KPIs. Year three should focus on refining emergency protocols and securing quick wins across some critical infrastructure. Natural flood management projects should have advanced in year four, complemented by community training. Finally, by year five, major infrastructure projects should be completed, with an evaluation of the effectiveness of all strategies.

In conclusion, addressing Nigeria's flood crisis requires immediate action, accountability, and a clear commitment to long-term resilience. By enhancing early warning systems, enforcing zoning regulations, investing in flood infrastructure, and fostering community engagement, Nigeria can mitigate the devastating impacts of floods. Effective flood management not only protects lives and property but also supports broader development goals, such as economic growth, food security, and social stability. With proactive measures, Nigeria has the opportunity to secure a future where communities are better prepared, livelihoods are protected, and the nation moves toward sustainable progress and climate resilience. The urgency to act now is undeniable, but the potential benefits are equally compelling, offering hope for a stronger and more resilient Nigeria.
