Flooding: Avoiding the fury of nature

 
Thu Oct 11th, 2018 - Adamawa
 

ON Friday, September 7, 2018, during an emergency stakeholders’ meeting, the Director of Engineering Hydrology, Nigeria Hydrological Services Agency, NIHSA, Mr. Clem Nze, warned that flooding is imminent and specifically noted that all the indices that played out before the 2012 flooding had all manifested. He said the decision to raise the alarm was to ensure preparedness among stakeholders and residents of flood-prone communities. 12 states in Nigeria have been listed to experience flooding this year due to torrential rainfalls.

It will be recalled that in 2012, the year of flood fury, about 360 lives were lost, with over two million people displaced. 30 States were said to have been affected by the floods, with Adamawa, Taraba, Plateau and Benue States being the worst hit by the disaster. It was estimated, according to National Emergency Management Agency, NEMA, that Nigeria lost N2.6 trillion to the 2012 flood disaster. These numbers of the displaced and lost lives and properties were those documented and recorded. The exact and specific numbers might be difficult to estimate as some cases might not have been documented. Would the 2012 flood disaster be said to be of a disaster foretold but ignored?

Flooding

Fastforward to 2018, two government agencies, NIHSA and NEMA have raised alarm that there is an impending flood as the downpour increases in the days ahead. Mr. Eze of NIHSA revealed that as at Friday, September 7, 2018, the height of River Niger in Lokoja was 10.1 metres as against the 9.7 metres in 2012, adding that it continued to rise on an hourly basis.

He said further, “as at today, our hydrological measuring station downstream the confluence in Lokoja recorded a stage height of 10.1m and a discharge value of 21, 236 cubic metres per second. As against lower values of 9.74m and 19,762 cubic metres per second recorded on the corresponding date of 2012 when the flood occurred.” He also added that the northern part of the country should expect more rains in the next three weeks.

A day after the timely flood alert and warning was issued by NIHSA and NEMA, we heard that in Jigawa, six people were feared dead and several others displaced due to flood. Also in Kogi, Kwara and Edo, farmlands and personal effects were destroyed. Early in September, Niger State recorded 14 deaths due to floods since the rain began this year. The days ahead would tell how these states and others would fare in the battle to escape from nature’s fury.

It is against this backdrop of recent floods in the country that we remind ourselves of the need to be ready for the peak of the rainy season. Put simply, flood is having too much water in the wrong place. The causes are clear. Sewage system blockages and rise in ground water level have been cited by some environmental experts as the main causes of flooding in Nigeria.

The Director General of NEMA, Engr. Mustapha Maihaja, said, “We are causing much of the adverse weather as we fell trees in multiples but fail to replace any, and you know that trees use up our carbondioxide and give up oxygen which we breathe. The felling of trees without replacement leaves more carbondioxide in the atmosphere which causes Ozone depletion. This simply means that the iceberg separating the sun from having direct impact on the earth causes rapid melting of the ice from above, while excess carbodioxide from the earth also enhances rapid melting of the ice from under. Thus, there is need for tree planting by everyone to checkmate the continuous heavy rainfall.”

He warned against refuse dumping in the drainages and also walking or driving during heavy rainfall, especially near drainage. The DG said: “It’s a United Nations call that people and governments should prevent hazards from developing into disasters, which is more cost effective than reacting to disaster effects. Thus, there is need for everyone to be empowered through capacity building against disaster effects.”

The peak of the rainy season in Nigeria is here and from experience, it comes with an attendant flooding. NIHSA, NEMA and Nigeria Metrological Agency, MiMet, have all raised red flag warnings for everyone to brace up for serious consequences advising flood-prone residents to vacate the areas.

With just few days of rains in this peak period of rainy season, shortly after the August break, houses have been submerged, farmlands inundated and lives already lost to floods in some states like Jigawa and Niger. Kogi, Kwara and Edo have also been tormented by the flood menace with its sorrowful consequences.

The federal government, in collaboration with relevant state agencies, especially states along the coastal regions, should as a matter of urgency evacuate residents of flood-prone areas and other danger zones to avert any flood devastation. The Nigerian Red Cross Society, NRCS, Humanitarian organisations and other relevant agencies are to be on standby to render necessary assistance to evacuated residents. The various camps where these flood-sacked victims would be accommodated albeit temporarily should be well-equipped with relief materials.

As a panacea for flooding in urban areas, government may consider building more water channels like canals, dikes and levees. Our preparedness for the peak of rainy season, effective natural disaster management and emergency response can, to a large extent, reduce the risk of flood disaster. We may not be able to prevent rains from unleashing floods, but we can mitigate adverse humanitarian effects.

National Orientation Agency, NOA, and NEMA are duty-bound to sensitise Nigerians on how to manage disasters and flood, and be disaster-resilient. Other government agencies saddled with disaster management are urged to double up in ensuring safety of lives during emergency.

Proactive measures taken by everyone now will go a long way in getting us ready for the predicted flood.
