How To Check Floods In Nigeria

Published

14 years ago

July 5, 2012

Flooding is a perennial problem caused by severe and torrential rainfall or rivers and oceans overflowing its banks as a result of high tides, thereby submerging land areas. In other words, floods could arise from a very large amount of water that has overflowed due to heavy downpour of rainfall or from a source such as river or a broken pipe onto a previously dry area. These are very common occurrences in coastal towns and other areas of the world like the Niger Delta part of Nigeria.

Rivers State, for instance, experiences flooding regularly and is prone to perennial flooding either when there is severe rainfall or high sea tide occasioned by increase in volume of rivers or the ocean.

Flooding takes place when lakes, ponds, river beds, soil and vegetation can not absorb all the water; water then runs off the land in volumes that can not be carried within stream channels or retained in lakes, natural ponds and man-made reservoirs. About thirty per cent of all precipitation becomes run off and that amount might be increased by water from melting glaciers.

Flood that rises rapidly with little or no advance warning is called a flash flood. Flash flood normally results from extensive rainfall over a relatively small area or if the area was already saturated from previous precipitation.

Flooding can be exacerbated by increased amount of impervious surface or by other natural hazards, wild fires or deforestation which reduce the supply of vegetation that can absorb rainfall. Moreover, flooding may occur due to severe winds over water, unusual high tides, tsunamis or failure of dams, retention ponds or other structures that retain water.

Flood also occurs in rivers when flow exceeds the capacity of the river or the sea channel particularly at bends or meanders. It often causes damage to homes, communication and electrical installations, businesses etc if they are located in natural flood plains of seas or rivers.

From time past, people have lived and worked by the water to seek sustenance and capitalise on the gains of cheap and easy travel and commerce by being close to the water. The fact that humans continue to inhabit areas threatened by flood damage is an evidence that the perceived value of living close to the water supersedes the cost of repeated periodioc flooding.

Meanwhile, the area geographically regarded and known as the Niger Delta with its estuary that empties into the Atlantic ocean is very prone or susceptible to flooding and its effect. This area is bordered by the coastline with its coastal shoreline that is characterised by flood plains which give rise to flooding just like other deltaic regions of the world. For instance, the Nile delta in Egypt that empties into the meditaranean sea, the Mississippi delta area of the United States that empties its water into the ocean and most of the areas or towns around these coastal regions experience various forms of flooding at different times of the year.

Coastal towns and cities in Nigeria, like Eket, Uyo, Port Harcourt, Bonny, Warri, Yenegoa etc. have suffered considerable losses from the effects of flooding. Flood has so many negative impacts. It destroys property and endangers the lives of humans and other living things including plants – vegetation; causes soil erosion and resultant sediment deposition elsewhere such as further downstream or down the coast. The breeding ground for fish and other marine life and wild life habitats become polluted or completely destroyed.

Prolonged high flood causes traffic obstruction and delays in areas that lack good drainage system or elevated roadways such as Rumuomasi/Market junction in Port Harcourt – Aba road, and Oroworukwo near St. John’s Bus stop on the same expressway. Flood does interfere with drainage and economic uses of lands, such as interfering with crop and animal farming. Structural damage could arise from bridge collapse, sewer lines, bank lines and other structures within floodways. Waterway navigation and hydro electric power are often impaired, including aviation navigation as flood could lead to delay or cancellation of flights or even cause crashes etc.

Only recently, the United Nations Envrionment Programme (UNEP) predicted that climate change will increase the risk of flooding in Europe and other parts of the world. According to United Nations (UN) report, in 1998, 23 million people were affected as a result of flooding in Xian, China including three thousand people dead. About one million people lost their homes. While in 1996, the monsoon flood in India affected more than five million people in the northern and eastern parts of the country. Severe floods have also killed over two hundred people in India and Bangladesh and left millions homeless.

Here in Lagos, Nigeria , in 2011, many lives were lost and valuable property worth millions of naira were lost to flood not to talk of the damage done to bridges, roads, communication lines etc. Similar thing is repeating itself this year.

It is pertinent to note that, flooding usually brings with it health hazards; it brings infectious diseases like malaria fever, pneumonic plague, dermatopethia, dysentery, common cold etc. And for areas which have no electric supply as a result of flooding, food poisoning may occur as food may not be properly frozen.

Therefore, for the world to be able to contain flooding which comes with its attendant dangers and tragedies, a wise society should build towns and cities in ways that can accommodate flooding and not trying to avoid it. Attempting to go against nature is most certainly risky. Man from time immemorial, has put in place measures to help check the menace of flooding. These measures include planting of vegetation to retain excess water, terracing hillsides to slow water flow downhill and the construction of floodways such as man-made channels or drainages to divert flood water.

A good example is the floodway channel being constructed by the Rivers State Government from Okporo road at Second Artillery all the way, to be diverted into the Ekere creek canal to help check flooding experienced in that area.

Other techniques that can be devised with increased development and advancement in technology to check flooding include the construction of dams, levees, dikes, reservoirs or retention ponds to hold extra water during times of flooding. Damming of rivers or seas and their associated reservoirs are designed completely or partially to assist in flood protection and control. Most large dams have flood control reservations in which the level of the reservoir must be kept below a certain elevation before the onset of the rainy season so as to allow a certain amount of space in which flood water can fill.

In many towns and cities, government could build river defences, since rivers are prone to floods if not properly managed. These defences include bunds reservoirs and levees. They are used to prevent rivers from bursting their banks. In the event of these defences failing, emergency measures such as sand bags or portable inflatable tubes are used. The issue of coastal flooding has been effectively addressed in Europe and Amercia with coastal defences such as sea walls, beach nourishment. In Lagos, the state government has adopted this approach in shoring up Bar Beach in Victoria Island, thereby proecting it from ocean surge as well as barrier islands.

Another measure that can help stem flooding is tide gates. This is used in conjunction with dikes and culverts. These gates can be placed at the mouth of streams or small rivers where an estuary begins or where tributary streams or drainage ditches connect to wet lands. Tide gates close during incoming tides to prevent tidal waters from moving upland and open during outgoing tides to allow water to drain out via the culvert and into the estuary side of the dike. The opening and closing of the gates is driven by the difference in water level on either side of the gate. These are good examples all the vulnerable states in Nigeria can implement especially in the coastal states to help check perennial flooding.

One of the most elaborate and largest flood control measures is found in the Netherlands, where they are referred to as delta works with the Osterschelde dam as its crowning achievement. The construction was made in response to the North sea flood of 1953 in the south-western part of the country. This is one giant measure taken by the Netherlands government to help control and mitigate the effects of flood year after year, as it is one of the most flood prone areas in the world. Nigeria stands to gain a lot if it can borrow a leaf from all these examples.

Tackling Nigeria’s Health Sector Challenges

Published

Quote: “A nation’s health system is not measured by promises made, but by the quality of care available to its people when they need it most.” mm

Every year on April 7, Nigeria joins the rest of the world in commemorating World Health Day, a day dedicated to reflecting on global health challenges and strengthening healthcare systems. The occasion, which marks the anniversary of the establishment of the World Health Organization (WHO), is often accompanied by speeches and policy declarations highlighting government efforts in the health sector. This year was no different. The Minister of State for Health and Social Welfare, Iziaq Adekunle Salako, reaffirmed the commitment of President Bola Ahmed Tinubu’s administration to improving healthcare delivery. Across the states, governments showcased their interventions, with Governor Siminalayi Fubara reiterating efforts to position Rivers State as a health tourism hub. While such declarations may inspire hope, they also raise an important question: how much of this commitment is reflected in the daily realities of ordinary Nigerians?

Despite years of promises and reforms, the nation’s health sector remains burdened by structural deficiencies, inadequate funding, and policy inconsistencies. The result is a system struggling to meet the needs of a growing population. One of the most pressing challenges is the continued migration of healthcare professionals. Doctors, nurses, pharmacists, and other skilled personnel are leaving the country in large numbers in search of better remuneration, improved working conditions, and greater career opportunities abroad. This persistent brain drain has widened the gap between available healthcare workers and the population they serve. With too few professionals left to cater for millions of Nigerians, hospitals are overstretched, waiting times are longer, and the quality of care is often compromised. Rural communities suffer the most, as many health facilities lack qualified personnel, forcing residents to travel long distances for basic medical attention.

Closely linked to this challenge is inadequate funding. For decades, budgetary allocations to health have remained below internationally recommended levels. Consequently, many public hospitals operate with obsolete equipment, poor infrastructure, and shortages of essential medicines. In several facilities, healthcare workers are compelled to improvise under difficult conditions, reducing the effectiveness of service delivery. The high cost of healthcare is another major concern. With only a small percentage of Nigerians covered by health insurance, most citizens pay for medical services directly from their pockets. For many households already grappling with economic hardship, healthcare expenses can be overwhelming. As a result, people often delay treatment, resort to self-medication, or seek help from unregulated providers, worsening health outcomes and deepening poverty.

Healthcare inequality between urban and rural areas further compounds the crisis. While major cities generally have better-equipped hospitals and a higher concentration of medical professionals, many rural communities are served by underfunded or non-functional primary healthcare centres. This imbalance leaves millions of Nigerians without access to quality healthcare and reinforces existing social and economic disparities. Industrial disputes have also become a recurring challenge. Strikes by healthcare workers, often triggered by unpaid salaries, inadequate welfare packages, and poor working conditions, continue to disrupt services and put lives at risk. The recent suspension of a nationwide strike by the National Association of Resident Doctors over salary arrears, hazard allowances, and residency training funding once again highlighted unresolved issues within the sector.

Another serious concern is the proliferation of counterfeit and substandard drugs. Weak regulatory enforcement allows fake medicines to find their way into the market, undermining treatment outcomes and endangering lives. Tackling this menace requires stronger oversight, stricter sanctions, and improved coordination among relevant agencies. Addressing these challenges demands more than ceremonial speeches or periodic interventions. Healthcare is not a luxury; it is a fundamental component of national development. A healthy population is essential for economic productivity, social stability, and sustainable growth. The theme of this year’s World Health Day, “Together for Health: Stand with Science,” underscores the importance of evidence-based policymaking and investment in innovation. Advances in medical science, digital health technology, vaccines, and diagnostics have transformed healthcare globally.

Nigeria must position itself to benefit from these innovations through increased investment in research, technology, and partnerships involving government, academia, and the private sector. More importantly, there must be sustained political will to implement reforms. The Federal Government should increase budgetary allocations to health, strengthen institutions, and ensure effective implementation of healthcare policies. State governments must also recognize their responsibility in delivering quality healthcare and invest accordingly. Retaining healthcare professionals should be a top priority. Better remuneration, improved working conditions, opportunities for career advancement, and incentives for service in rural communities would help reduce the exodus of skilled personnel. Expanding health insurance coverage is equally critical to reducing out-of-pocket expenses and making healthcare more accessible to vulnerable populations.

Strengthening primary healthcare is another urgent necessity. As the first point of contact for most Nigerians, primary healthcare centres must be adequately equipped, properly staffed, and effectively managed. Investments at this level would improve health outcomes, reduce pressure on tertiary hospitals, and bring healthcare closer to the people. Ultimately, the condition of a nation’s health sector reflects its priorities. A government genuinely committed to the welfare of its citizens cannot afford to treat healthcare as an afterthought. As Nigerians mark World Health Day, attention must shift from rhetoric to action. The challenges facing the sector are well known, and the solutions are within reach. What is needed now is bold, sustained, and sincere commitment to reform. The health and wellbeing of millions of Nigerians depend on it.

2): At 59, Rivers’ Agropotential Lost?

Sylvia ThankGod-Amadi

Quote: “No society can sustainably prosper when it neglects the sector that feeds its people, creates jobs, powers industries, and secures its future.”

As Rivers State marks 59 years of its creation, there is every reason to celebrate its achievements in politics, infrastructure, commerce, education, and human capital development. Yet, amid the celebrations, one critical question demands attention: what has become of agriculture, once a major pillar of the state’s economy? Before crude oil became dominant, farming, fishing, and livestock production sustained livelihoods across communities such as Etche, Ikwerre, Ahoada, Ogba, Abua, Kalabari, Andoni, Opobo, Khana, Gokana, and Tai. Families depended on proceeds from cassava, yam, cocoyam, maize, vegetables, oil palm, fish, and other agricultural products to fund education, support households, and drive local commerce. Recognising agriculture’s importance, successive governments introduced programmes aimed at increasing food production and modernising farming.

Investments were made in extension services, fish farming schemes, livestock development, youth empowerment initiatives, and farm settlements. One notable intervention was the Songhai Farms project in Bunu-Tai, established to train young people in modern integrated farming and agribusiness. Governments also distributed improved seedlings, fertilisers, fishing equipment, and supported cooperative societies to encourage productivity and value addition. Despite these efforts, the outcomes have largely fallen short of expectations. Many projects suffered from inadequate funding, poor implementation, or policy discontinuity. Programmes launched by one administration were often abandoned by another, resulting in wasted resources and unrealised goals. At the same time, the dominance of oil revenue reduced interest in agriculture.

As opportunities expanded in the oil and gas sector, many young people abandoned farming, which gradually became associated with hardship and poverty rather than prosperity. Environmental challenges further weakened the sector. Oil spills, gas flaring, flooding, erosion, and pollution have damaged farmlands, rivers, and creeks across the state. Communities that once relied heavily on farming and fishing have seen productivity decline due to ecological degradation. These challenges continue to discourage investment and limit agricultural growth. Today, Rivers State faces a troubling paradox. Despite its vast arable land, abundant water resources, favourable climate, and large consumer market, it relies heavily on food supplies from other parts of Nigeria. Tomatoes, rice, vegetables, fish, and poultry products consumed in local markets are often transported from distant states. This dependence exposes the state to rising transportation costs, inflation, supply disruptions, and food insecurity.

Whenever insecurity, flooding, or fuel price increases affect transportation networks, food prices in Rivers State rise sharply, placing additional pressure on households. These realities highlight the urgent need for an agricultural renaissance. At 59, Rivers State must relaunch agriculture not as a political slogan but as a strategic economic priority. Such a relaunch should begin with a comprehensive agricultural master plan that transcends political administrations. Agriculture requires consistency and long-term commitment, since farmers invest over seasons rather than election cycles. Youth participation must be central to this new vision. Modern agriculture is increasingly driven by technology, mechanisation, innovation, and entrepreneurship. Greenhouse farming, aquaculture, poultry production, food processing, hydroponics, and agritech solutions have transformed agriculture into a profitable business globally.

Rivers State can establish agricultural incubation centres where young people receive training, access to land, start-up support, and mentorship, thereby creating a new generation of agripreneurs while tackling unemployment. Access to affordable finance is equally important. Many farmers struggle to secure credit because of stringent lending conditions. Government can partner with financial institutions to create specialised agricultural financing schemes offering low-interest loans and flexible repayment options. Strengthening cooperatives would also improve farmers’ access to resources, markets, and modern inputs. Infrastructure development remains critical. Good road networks linking rural communities to urban markets would reduce transportation costs and post-harvest losses. Investments in storage facilities, cold rooms, processing centres, and rural electrification would improve productivity and profitability.

Particular attention should be given to aquaculture. With its extensive rivers, creeks, wetlands, and coastline, Rivers State has enormous potential to become a major fish-producing hub, creating jobs and reducing dependence on imports. The oil palm subsector also presents significant opportunities. Before the oil boom, the Niger Delta was renowned for palm oil production. Revitalising plantations and supporting smallholder farmers can stimulate agro-industrial development, increase export earnings, and strengthen rural economies. Beyond economic gains, agricultural revitalisation offers important social benefits. Increased food production can lower food prices and improve nutrition. Job creation can reduce poverty, youth restiveness, and rural-urban migration. Agriculture also supports a wide range of value-chain activities, including transportation, processing, packaging, marketing, and equipment maintenance, creating multiplier effects throughout the economy.

Communities where young people are productively engaged are generally more stable and secure. Food security has become an increasingly urgent national concern. Recent economic challenges and inflationary pressures have exposed the risks of relying heavily on food supplies from distant locations. A state that can feed itself is better positioned to withstand economic shocks and uncertainties. As Rivers State celebrates its 59th anniversary, the occasion should inspire renewed commitment to agricultural development. The state possesses the land, water, climate, manpower, and market needed for success. What remains is the political will, strategic planning, and sustained investment required to unlock these potentials. The future prosperity of Rivers State cannot depend solely on oil revenues whose fortunes fluctuate with global market forces. Diversification is no longer optional; it is an economic necessity.

Fifty-nine years after creation, the message is clear: Rivers State must return to the land—not as a retreat to the past, but as a bold investment in a more secure, prosperous, and sustainable future. Agriculture remains one of the surest pathways to food security, employment generation, inclusive growth, and economic resilience. The seeds of that future already exist in our soil. What is needed now is the collective determination to cultivate them.

Monthly Environmental Sanitation Imperative

Published

2 weeks ago

May 18, 2026

The Tide

Quote: “A clean environment is not a government gift; it is a civic duty that protects our health, preserves our cities, and reflects our national character.”

For many Nigerians who grew up in the 1980s, 1990s, and early 2000s, the last Saturday of every month followed a familiar pattern. Roads were deserted, markets closed, and residents swept compounds, cleared gutters, cut overgrown weeds, and disposed off refuse. The monthly environmental sanitation exercise became a national ritual that promoted cleanliness, discipline, and civic responsibility. As an environment correspondent about two decades ago, I joined officials of the Rivers State Ministry of Environment on sanitation monitoring tours across Port Harcourt and surrounding communities. Although enforcement officers were sometimes accused of excesses, the exercise succeeded in creating public awareness about the importance of keeping our surroundings clean. Over time, however, the practice faded away in many states.

In its absence, indiscriminate dumping of refuse, blocked drainages and environmental neglect became increasingly common. Today, heaps of waste line roads, markets and motor parks, while gutters clogged with plastics contribute to perennial flooding. Given the mounting environmental challenges facing Nigerian cities, there is no better time to revive environmental sanitation. Its return is no longer a matter of nostalgia; it is a practical necessity for public health, environmental safety, and sustainable development. Poor sanitation remains a major cause of disease. Stagnant water and uncollected waste create breeding grounds for mosquitoes, flies and rodents, increasing the risk of malaria, cholera, typhoid and other infections. Floodwaters contaminated by refuse also expose communities to serious health hazards.

Rapid urbanisation has worsened the situation. Cities such as Lagos, Port Harcourt and Abuja are expanding faster than their waste management systems can cope. As populations grow, so does the volume of waste generated daily. Monthly sanitation exercises can help rebuild environmental consciousness. Beyond cleaning streets, they remind citizens that environmental cleanliness is a shared responsibility. They also offer an opportunity to educate children and young people about hygiene, public health and community participation. Critics argue that the old sanitation policy restricted movement and was sometimes abused by security personnel. Those concerns were valid, but they do not invalidate the concept itself. Rather than abandon it, governments should reform the programme to make it more humane, participatory and transparent.

That is why the recent decision by the Lagos State Government to reintroduce monthly sanitation deserves commendation. Even if participation is largely voluntary, the move sends a strong signal that environmental responsibility must be taken seriously. Other states should emulate this initiative. In Rivers State, the Rivers State Waste Management Agency has intensified efforts to improve waste collection and restore Port Harcourt’s reputation as the Garden City. Reintroducing monthly sanitation would complement these efforts and deepen public involvement. At the federal level, policies such as the Digital Waste Marketplace, the Plastic Waste Policy and the National Waste Management Network are commendable. However, environmental sanitation remains one of the most direct and visible ways to mobilise citizens toward cleaner communities.

The exercise, however, must be supported by efficient waste management infrastructure. Citizens cannot be expected to maintain clean surroundings if there are inadequate waste bins, irregular refuse collection, and limited recycling facilities. Governments at all levels should invest in modern waste management systems, properly fund sanitation agencies, and promote recycling programmes. Waste sorting should become standard practice to reduce the volume of refuse ending up in landfills and drainage channels. Countries such as Singapore, Sweden and South Korea have demonstrated that waste can become a valuable economic resource. Recycling industries in these countries create jobs while protecting the environment. Nigeria can adopt similar strategies and turn waste into wealth.

Environmental laws must also be enforced consistently. Regulations against illegal dumping exist in many states but are rarely implemented. Offenders should face penalties, but enforcement must be fair and free from extortion. Urban planning is another critical factor. Poor drainage systems, overcrowding and inadequate sewage infrastructure worsen sanitation problems. Governments must prioritise road construction, drainage maintenance and orderly urban development. Markets deserve particular attention. They generate enormous quantities of waste every day, yet many lack organised disposal systems. Local councils and market associations should work together to establish effective waste collection arrangements in commercial centres. Religious institutions, schools, traditional rulers and civil society groups also have important roles to play.

Environmental responsibility should be taught and reinforced as a social value. Community leaders can help change attitudes by consistently promoting cleaner habits. This issue is even more urgent in an era of climate change. Flooding, erosion and extreme weather events are already threatening many Nigerian communities. Poor waste disposal worsens these challenges by blocking waterways and reducing urban resilience. A clean environment also offers economic benefits. Well-maintained cities attract investors, tourists and businesses. Reduced disease outbreaks lower healthcare costs and improve productivity among workers and students. More importantly, cleanliness reflects national values. A nation that allows public spaces to deteriorate projects an image of disorder and neglect. Nigerians deserve cleaner streets, healthier neighbourhoods and safer communities.

Reviving environmental sanitation will not solve all environmental problems overnight, but it can serve as a powerful starting point. Combined with effective waste management, public education and stronger infrastructure, it can restore environmental consciousness across the country. Ultimately, environmental cleanliness is a shared responsibility. Government must provide leadership, infrastructure and enforcement, while citizens must demonstrate discipline and civic commitment. From disposing of household waste properly to keeping drains free of obstruction, every Nigerian has a role to play. If Nigeria is serious about protecting public health, reducing flooding and building livable cities, the return of monthly environmental sanitation is a step whose time has come.
