How To Check Floods In Nigeria

Published

on

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.

Taking The War To The Enemy

Published

on

Heat not a furnace for your foe so hot that it do singe yourself – King Henry VIII.

On July 30, 1966, a message intercepted in some monitoring quarters read as follows: “It is not over yet. Battle will be taken to the enemy’s home camp”. Without giving away further details, any serious investigator can find out what happened in Nigeria between July and December 1966, commonly called counter or second military coup in Nigeria.
When the current Inspector General of Police came to Rivers State recently to flag off a security outfit, there was a statement about taking the war to the camp of the enemy, rather than wait to be attacked first. Without revisiting the Nigerian Civil War, what gave rise to it and matters arising from it, there is a need that we be honest with ourselves. Being honest with ourselves would include admitting that the intercepted “top secret” message of 1966 was a clarion call in some quarters. In a similar way, it would be naïve to ignore certain utterances and actions coming from some quarters since 1966.
A hackneyed idiom that “Rome was not built in one day” is a reminder that the task of nation-building takes quite some time, patience, honest collaboration and patriotism. Yes, mistakes had been made in the past which included tolerating and pampering wrongs that were swept under the carpet. Similarly, we did not have the courage to tell ourselves that a war indemnity was cleverly imposed on a certain section of the country, since 1970.
Let us admit that what was known colloquially as the “Kaduna Mafia” came into existence and in connection with the intercepted security message of July 30, 1966. What became alarming to the few people privy to that message was a threat that “future generations will continue to pay for this audacious assault”. What was the audacious assault? That would be revisiting the military coup of January 15, 1966, which had been interpreted in some quarters as an assault on the North, by Igbo Army officers. Was it?
Let us admit that despite the “revenge coup” of July 1966 and the Nigerian Civil War (1967-1970), that threat about future generations continuing to pay some price was neither empty nor is it over yet. The tag of hate speech would definitely not include saying the truth, so long as the way the truth is revealed does not jeopardise national security or unity. The purpose of what is being said here is to admonish that when vengeance is taken too far, it can become counterproductive. That is the essence of the quotation at the beginning of this article, coming from Shakespeare’s King Henry VIII.
Those who have taken the pains to study the trends of the decline of various powers and regimes in history, would have cause to express some fears about the future of Nigeria. The habit of showering praises and flatteries on rulers and leaders rarely demonstrates utmost good faith or patriotism. Rather, any leadership that thrives on and encourages such practices rarely hears the footprints of the ants. It takes deep introspection to be able to explore the “grapevine” in any system of management.
To say that security is a major challenge in the country currently is correct to the extent that prejudices can be kept aside in any effort to explore what brought us to where we are now. Surely, every country has its peculiar challenges which also include security. In every genuine effort to address security issues, it is expedient to look inwards in an honest self-examination. While it is easier and more common to blame everyone else when things begin to fall apart, wisdom would demand that we search ourselves first before pointing fingers at others, using the language they understand.
For quite a long time, a few honest Nigerians have been pointing out where things are going wrong in the country, with nothing serious being done to look into them. The most current is the Petroleum Industry Bill about to be signed into law. One Rev. Canon Chuka Opara, apart from pointing out how Southern lawmakers allowed themselves to be outwitted by their more alert Northern counterparts, said something revealing: “never you be eager to befriend anyone whose desire is always to cheat you” – ref. The Tide newspaper: Monday 12/7/2021.
To put the matter bluntly, there is a growing awareness in Southern Nigeria that there is a cheating game going on in the country. Was Femi Fani-Kayode wrong to say that “President Buhari’s Fulani cabal has conquered Nigeria?” After an unguarded statement by one Badu Salisu Ahmadu that there is a standing Fulani Strike Force ready to take over Nigeria, was he arrested or interrogated by security agencies? Neither did Dr. Obadiah Mailafia cry wolf when there are none.
It was late Senator Francis Ellah who raised the issue of a clever imposition of some penalty on South-Eastern Nigerians arising from the Biafra issue. But rather than address the issue with honesty, there have been series of acts of subterfuge and intimidation, making the people feel more bitter and estranged. Neither do we have the honesty to admit that the rising agitations from that part of the country has to do with disenfranchisement of the people of their natural resources. The issue of resource control is obviously dead now.
The more brazen acts of disrespect for the rights of South-Easterners include the invasion of their farmlands by marauding cattle, with no visible action seen to be taken by the Federal Government to check the impunity of herdsmen. Rather, there were appeals for Southern states to provide lands for Ruga and ranching, as if cattle business is state business rather than a private one. Even with a belligerent attitude of the organised body of cattle dealers, Miyetti Allah, the impression Southerners get is that they are being treated like a conquered people.
Partisan politics apart, the impression must not be given that the APC-led Federal Government is out to intimidate or oppress South-Easterners. Currently, the Ijaw ethnic nationality is holding consultations on how to leave Nigeria, quite apart from the Sunday Igboho issue. The time has come to ask if a section of the country is not unwittingly creating or heating the furnace so hot for us to bear. We were told that there was no victor, no vanquished in 1970, but there are overlords.

Big Brother No More

Published

on

The Sierra Leonean High Commissioner to Nigeria, Dr Solomon Gembeh, was recently reported as saying that Nigeria spent over $13 billion on the liberation of his nation and Liberia. According to him, Sierra Leone would remain ever grateful for Nigeria’s ‘big brother’ interventions in the fratricidal wars that were launched by rebel groups in the two contiguous West African neighbours.
Gembeh emphasised that Nigeria’s assistance came out of goodwill, with nothing demanded in return, unlike a situation where such help (especially from Western nations) was paid for through the staking of national assets. He said that funds from Nigeria and the African Development Bank (AfDB) were efficiently being used to train Sierra Leonean children, particularly the girls.
“We provide what we enjoyed when we were in primary school, we enjoyed lunch served; you have free buses to take you to school; you eat there; and there are teachers everywhere.
“People are beginning to get computers, trying to get Internet services all over the schools; places that are hard to reach you make sure that they don’t walk so many miles to get to school,” said the diplomat.
Gembeh used the opportunity to remind the Nigerian government of its unfulfilled funding pledges to his country and hoped that such friendly aid would help restore the education system for a generation of Sierra Leonean children who lost a decade of proper schooling as a result of the civil war.
It would be recalled that the Liberian and Sierra Leonean Civil Wars were fought mainly between militia groups which craved to control the rich diamond mines in these countries. It actually started in December 1989 when Charles Taylor’s National Patriotic Front of Liberia (NPFL) attempted to oust the military government of Sergeant Samuel Doe.
The internal struggle spilled over to Sierra Leone when a splinter gang of the NPFL, known by the ULIMO acronym, which occupied Liberia’s western region crossed the border into Sierra Leone to fight Taylor’s forces from there. The Sierra Leonean Army would have none of that in their country. But ULIMO was too hot to handle. So, Guinea and Nigeria had to ship in military supplies to help Freetown chase out the intruders. While this lasted, an indigenous rebel group, the Revolutionary United Front (RUF) led by Foday Sankoh and suspected to be supported by Taylor, sprang up in 1991 to take up territory of its own. And that was how a brutal civil war ensued in the once tranquil former British colony.
A multinational force was raised by the Economic Community of West African States (ECOWAS), named as ECOWAS Monitoring Group (ECOMOG), to restore and monitor peace in both countries.
In her usual character to always play the big brother in Africa, it was reported that Nigeria had readily opted to contribute the bulk of the troops and materiel that went into the regional peacekeeping effort. This obviously accounted for her anger and immediate takeover of the ECOMOG high command when President Doe was captured, brutally tortured and killed under the nose of a Ghanaian commander, Lt. Gen Arnold Quainoo.
One is not averse to Nigeria playing major roles in regional and global affairs. After all, isn’t that the dream of every patriotic citizen of any country? I still remember a CNN footage of troops of the Nigerian ECOMOG contingent fanning out in the Liberian capital as they were ferried ashore from a warship and under heavy attack by Taylor’s men. Honestly, I had never felt prouder of our soldiers as they moved quickly to liberate Monrovia and save people from further anguish. It reminded me of those pictures of World War II Normandy Landing in 1944.
If indeed Sierra Leonean primary school kids are beginning to be bused to school where they eat free lunch, have access to good teachers and Internet facilities as claimed by Gembeh, then they can be said to be already ahead of their Nigerian contemporaries.
Down here, reliable statistics have always placed the number of our out-of-school children at a conservative 10 million. Some of those considered lucky to attend school do so trekking long distances or paying their ways to and from school. Save for the few states where a federal government-sponsored school-feeding scheme has been introduced, Nigerian kids mostly fend for themselves while in school. As for Internet access, many rural kids may not even have seen a computer since registering at school.
Liberia, Sierra Leone and other beneficiary countries should please make do with whatever helps that came from Nigeria in their most trying times. They should forget any outstanding pledges because the so-called big brother is now in some dire straits of his own and wishes that those beneficiary nations begin to act as big uncles to him. And who said Nigeria is not at war right now; what with al-Qaeda’s Boko Haram/ISWAP insurgents in the north east and the itinerant bandits elsewhere in the land? Surely, Abuja will greatly appreciate a return of any previous favours and goodwill at this time.
What’s more, during our major bloodlettings in the 1960s only Ghana’s General Joseph Ankrah made any serious attempt to try to mediate between Colonels Yakubu Gowon and Emeka Odumegwu-Ojukwu in order to avert the kind of carnage that was witnessed in the Nigerian Civil War. The rest of Africa took sides on the sticking points at Aburi or were simply not interested; including the then Liberian President William Tubman and Prime Minister Siaka Steven of Sierra Leone who were not moved by pictures of gravely kwashiorkored Biafran kids.
Enough of this African big brother histrionics, please. Even the US is rethinking her global big brother posturing.

For A Stronger Opposition Party In Nigeria

Published

on

For want of a better phrase, I will describe this week as a period of “push me, I push you” for the ruling All Progressives Congress (APC) and the main opposition party in the country, the People’s Democratic Party (PDP).
It started with the PDP Governors in a communiqué at the end of their 11th meeting in Bauchi State on Monday, accusing the President Muhammadu Buhari-led administration and the APC of turning the Presidential Villa to the new APC headquarters and using underhand tactics to arm-twist some PDP governors and other stakeholders to join the ruling party.
Then the Presidency which in its usual manner cannot take such allegation lying low, through the Special Adviser to the President on Media and Publicity, Femi Adesina, lampooned the opposition party, boasting that “between now and 2023, there would be more confusion in their ranks and there would be more depletions in their ranks, so that is why they say anything,” he said.
According to him, “We were in this country when President Obasanjo was in power and the BOT meeting of the PDP used to hold at the Presidential Villa.
“We were here when President Yar’Adua, and President Jonathan was there, they held meetings at the Presidential Villa. What are they talking about really? Meaning, yes, we (the APC) are using the villa as a party office today because you (the PDP) used it in the past.
 So we are still where we were in 2015 when PDP left office. Nothing has changed? The wrongs of the now opposing party are still being perpetrated despite all the promises to bring about change? Maybe this mentality of “business as usual” is the reason the three major campaign promises of the ruling power tackling insecurity, improving the economy and fighting corruption are yet to be realized.
From the realities on the ground, it is obvious that the country is not any better today than it was six years ago. We have seen a complex form of insecurity threatening to tear the country apart. Many citizens have been sacked from their ancestral homes by bandits, herdsmen or whatever they are called; hundreds of people are being killed every day, kidnapping for ransom has become a lucrative business; many farmers can no longer go to their farms for fear of being raped, maimed, kidnapped or killed.
 Economically, there is little or no visible improvement. Currently, Nigeria is topping the list of countries with the most people living in extreme poverty in the world. Unemployment rate is on the increase and the value of the Naira continues to depreciate. Corruption is now the order of the day. Some people liken corruption in the country to cancer that has destroyed every part of the body.
Yet, all we hear is that the government is doing a lot for the country. The Presidential spokesman, Adesina, announced a few days ago that the Buhari government will unveil massive infrastructure in the country by 2022. Let’s keep our fingers crossed and see what they have in stock and what impact it will make in the lives of the numerous poor citizens.
But the desired change is not the responsibility of the APC alone. Put differently, the blame for the lack of change should not go to only the ruling party.  Has the PDP as the main opposition party been able to put enough pressure on the APC to bring about change? By this, I do not mean the frequent press releases and communiqués whose impact is hardly felt.
Has the PDP demonstrated good governance styles in the state they control which can put pressure on the APC to sit up?  In the aforementioned communiqué the PDP governors supported the need for a free, fair and credible election in the country and asked the National Assembly to entrench electronic transmission of results of elections in the nation’s electoral jurisprudence.
The big question is, have these governors done the same in their various states?  Have they given free hand to their respective State Independent Electoral Commissions (SIECs) to conduct free, fair and credible elections that will be acceptable by all or they have made their state electoral umpire an extension of their political party? 
Yes, it is good to criticise the federal government and the party in power when things are not going as expected or when their actions and inactions are causing untold hardship and pain to the citizens, but as leaders of government in opposition party controlled states, the governors need to go beyond criticisms and attacks.  A lot of Nigerians will like to see them exemplify their own alternative good governance style so convincingly that people in states controlled by other parties will want to support or vote for PDP candidates in their areas so as to be able to enjoy good governance.
Again, the PDP governors demanded Electronic Transmission of 2023 Election Results and many have been wondering why, as a party, they can support such a course while some senators elected on the platform of the party voted against it and some stayed away on the day the Senate voted to decide the inclusion of electronic transmission of election results in the proposed amendments to the Electoral Act.
It is, therefore, time for the leaders and members of the PDP to come together and think of a better, more effective way to play their opposition role if they must effectively challenge the APC in the next election. The ongoing zonal congress of the party should be free and fair, devoid of imposition of candidates or overbearing influence of the party heads so that the party will be united and not fractionalised, going into the 2023 General Election.
