The Root Cause Of Flooding In Nigeria

According to the world health organization (WHO) Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.

Floods can cause widespread devastation, resulting in loss of life and damages to personal property and critical public health infrastructure. Between 1998-2017, floods affected more than 2 billion people worldwide. People who live in floodplains or non-resistant buildings, or lack warning systems and awareness of flooding hazard, are most vulnerable to floods.

Between 80-90% of all documented disasters from natural hazards during the past 10 years have resulted from floods, droughts, tropical cyclones, heat waves and severe storms. Floods are also increasing in frequency and intensity, and the frequency and intensity of extreme precipitation is expected to continue to increase due to climate change.

Floods can also have medium- and long-term health impacts, including:

water- and vector-borne diseases, such as cholera, typhoid or malaria.

injuries, such as lacerations or punctures from evacuations and disaster cleanup

chemical hazards.

mental health effects associated with emergency situations.

disrupted health systems, facilities and services, leaving communities without access to health care,damaged basic infrastructure, such as food and water supplies, and safe shelter.

According to the Nigerian guardian newspaper reports on damages caused by floods currently in 2020.

Flooding has cut off some communities from other parts of the state in a devastating around Hushi, Sokoto State.

Hushi, a renowned farming and fishing community, has turned ‘island,’ where the major link-way, Hushi-Wurno road, collapsed at three remote points following heavy downpours and massive flooding.

No fewer than 11,356 persons were affected by flood in six local councils, with 5,200 people displaced, 30 persons injured and 15 deaths in the recent Kebbi State flood disaster.

Dangerous reptiles have began to creep into some residential houses in Ogbaru Local Government Area of Anambra, as a result of flood.

Ogbaru is a coastal local government with all its 16 communities on the banks of River Niger.

On 5-6 September, heavy rain and associated flooding affected Kano State (northern Nigeria), leading to fatalities, displaced people and damage. Media report that 2 people died and more than 5,000 houses were destroyed in Danbatta Area, 2 fatalities and over 200 damaged houses occurred in Rogo Area. Flooding was reported across more than 20 Local Government Areas of Kano State, and a number of people have been displaced. Recent flooding across Jigawa, Kano, Kebbi and Sokoto States in northern Nigeria have caused around 30 fatalities and damage to thousands of homes and crop fields. Moderate to heavy rain is forecast over central and northern Nigeria on 7-8 September.

The Root Cause Of Flooding In Nigeria

The major root cause of flooding in Nigeria include:

1.pollution

2.Unauthorized Buildings

1.Pollution:

Fossil CO2 emissions in Nigeria were 82,634,214 tons in 2016.

CO2 emissions increased by 0.70% over the previous year, representing an increase by 578,039 tons over 2015, when CO2 emissions were 82,056,175 tons.

Nigeria is ranked number nine in the list of top twelve mismanaged plastic waste polluters in the world in 2010, contributing 2.7% to the world Total plastic waste pollution.b

Due to the fact that Nigeria emits high amount of CO2 into the atmosphere,and CO2 is one of the green house gases that have the ability to trap heat.The warmer the atmosphere gets as a result of CO2 emission the higher the precipitation,and it's scientifically proven and evident that high amount of precipitation is one of the major root causes of Flooding therefore directly or indirectly air pollution contribute to flooding in Nigeria.

The fact that Nigeria is one of the world's largest Plastics polluters,and plastics are known to have stubborn nature in decomposition,plastics thrown into water bodies like rivers and lakes gather up and eventually block the free flow of water,as a result of that whenever there is high amount of rainfall, instead of the water to flow freely,it remain stagnant and eventually overflow resulting to flooding in riverine areas.

Plastics thrown into sewers also result to blockage of the sewers hindering the free flow and passage of liquid waste to their appropriate destination,as a result of this when there is high amount of rainfall an overflow occurs flooding main roads and houses around the area.

2.Unauthorized Buildings:

It is a sad reality that most of the houses in Nigeria are built either in areas that are mapped out of residential areas,or built without following the standard rules and regulations involved before mounting a house which include soil investigation to know whether the soil is suitable for the type of building you intend to mount,the typography of the area,how far is it from a water body,how many meters should be left out away from a water body before mounting a house and the height a house in a riverine area should attain.

Most of the victims of flooding are low class families that have no knowledge of these rules and regulations,in a situation where by they are aware they don't have enough resources whatsoever to abide by the said regulations.

Infact there main concern is to have a place to rest at night,wake up in the morning and hustle for what to eat.

In such circumstances even if a forecast of impending flood is announced to the public,these set of people still get victimized because they have no other place to go to for safety.

Plots of lands located in riverine areas are cheap and affordable, that is the main reason less privilege citizens reside in such areas.

Possible Solutions To Flood In Nigeria

1.Climate action should be taken by both the government and the citizens of Nigeria.

2.Pollution should be controlled, government should came up with efficient recycling centers in the country in other to manage waste properly.

3.To reduce carbon emission industries should alternate the use of carbon producing materials with less harmful ones

4.plot of lands at approved residential areas should be made cheap and affordable for the less privilege citizens.

5.Free awareness on rules and regulations for a sustainable building should be given from time to time to the masses,either physically or through mass media.

Closing the Gap: Accelerating Nigeria’s Progress on SDGs through Innovation and Partnerships

The United Nations Sustainable Development Goals Report 2025 paints a sobering picture: the world is halfway to the 2030 deadline, but only about 15% of the targets are on track globally. For Nigeria, the report highlights mixed progress, strong strides in mobile connectivity and gender representation in politics, but slower movement on poverty reduction, quality education, and clean energy access. Check my previous post to know more about the United nations SDGs 2025 Report This chapter zeroes in on how Nigeria can close the gap, drawing from both the UN’s recommendations and real, local examples of innovation and partnership making a measurable impact. The SDG Challenge in Nigeria The UN report identifies three key bottlenecks in Nigeria’s SDG journey: 1. Funding gaps: Development financing remains well below the estimated $100 billion annual requirement to achieve the SDGs. 2. Data gaps: Limited real-time data makes it difficult to monitor progress and direct resour...

The Ozone Layer

Have you ever wondered what is special about these ozone layer you are seeing here and there on each post concerning climate change and other related environmental issues,well you have come to the right place to get the right information. Ozone Layer: Ozone Layer chemically represented as O3,is a layer found in the atmosphere,it occupied 70% of the stratosphere. The Ozone Layer is a protective blanket that protects the earth from ultraviolet rays,it protects the earth by absorbing the harmful rays coming into the earth surface,and letting only the usable one that can be absorbed by plants and animals without adversely affecting them reach the earth surface. The three molecules of oxygen that binds together to form the ozone layer (O3) are what makes the ozone layer special and thus,referred to as a protective blanket. Whenever the bond between the oxygen molecules breaks,the earth is no longer safe,the ozone layer start to deplet,and a hole is formed,when this happens ...

Why Save The Earth

Many people have been asking and wondering why are they always asked to use this and not use that,dump this and don't dump that,do this and don't do that,why do we have to safe the earth anyways,we are all going to die one way or the other,so why bother. Calm down and read very carefully,all you questions are going to be answered. First of all we need to save the earth because it is our home,we have no other place to go,just like we wake up everyday and clean our houses,dust the bed,repair the roof to live comfortably close the doors before going to bed in other to sleep peacefully. The earth also need to be protected from all foreign substances that could trigger Climate change,flood, draught,wild fire e.t.c for both plant and animals to live comfortably and have a healthy life. Secondly the earth need to be protected not only for us to enjoy,giving that we are all going to die eventually,the earth needs to be protected for future generations to come. The future generations ...

Global warming

What Is Global Warming? Global warming is the increase in atmospheric, earth surface and ocean temperature caused as a result of combination of high amount of carbon monoxide (CO2) and other green house gases. Green house gases are naturally found in the atmosphere in minute quantity,the industrial activities taken place on the earth surface as a result of human persistency in acheiving development and easy living are the primary source of excess release of the green house gases into the atmosphere,such activities include burning of fossil fuels, gas exhaust from vehicles in form of CO2. All these gases that accumulates in the atmosphere trap heat that is bounce back from the earth surface to the atmosphere after the required amount is used by both plant and animals. The heat that bounces back are no longer needed by the earth surface and are meant to escape to outer space. But because of the green house gases trapping the heat,the earth surface gets hotter and hotter,this is known as ...

PLANT NURSERY ESTABLISHMENT

NURSERY ESTABLISHMENT Nursery is a place where seeds are raised to seedlings. A nursery can be temporary, permanent,oasis nursery or floating nursery depending on the number of seedlings that needs to be raised, space availability, weather conditions,water source, accessibility,demand, terrain and the type of seed. There are various processes involved in establishing a nursery these processes include 1.Seed procurement 2.Land clearing 3.Fencing 4.Sand filling 5.Watering 6.Stacking Seed application e.t.c SEED PROCUREMENT A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, Seed procurement involves the collection and preservation of seeds, there are many processes involved in seed collection and preservation. After collection some seeds are preserved inside hot water while some prefer cold water,the seed is then put inside a preservation tray for sun...

Waiting to be discovered: the Plastic waste recycling industry

Waiting to be discovered: the Plastic waste recycling industry Plastic pollution occurs due to the accumulation of plastic in the environment. Plastic is a versatile compound made up of repeatedly long chains of molecules interlinked together. It can take various forms and shapes. Plastic is used in almost every sector including in building and construction, packaging, and also in electronic and industrial machinery. Accumulation of plastic is a problem because it does not decompose. Its reversible nature makes him a dangerous compound. Normally plastic items usually take 1000 years to decompose. One of the most important and concerning problems in developing nations is plastic pollution, which has a significant negative influence on both the environment and human health. Unfortunately, in Pakistan, there hasn't been much work done on this subject. The average amount of plastic garbage produced annually per person ranges from 69 kg in Japan and Korea to 221 kg in the United Stat...

SUSTAINABLE DEVELOPMENT: MY IDEAL NATION'S HOPE FOR A BETTER FUTURE

SUSTAINABLE DEVELOPMENT: MY IDEAL NATION'S HOPE FOR A BETTER FUTURE Nigeria is currently faced with numerous issues that accumulated and leads to continuous backwardness in economic growth; this is a result of climate change, insecurity and gender inequality. The continues uncontrolled exploitation and over dependency on non renewable energy sources( coal, petroleum, and natural gas), Unsustainable agricultural practices, improper waste management practices, deforestation and other unsustainable habits have led to the increased rise of greenhouse gases(Co, Nox, Sox, methane e.t.c) into the atmosphere, such gases are heat trapping-gases capable of trapping excess heat in the atmosphere which cause a rise in the global average temperature and eventually lead to global warming and climate change. The NOAA report shows that the global mean temperature between January and September 2021 was around 1.08 ±0.13 °C above the 1850-1900 pre-industrial average. The year is likely ...

Mindful Living for a Green 2026: Start Small, Stay Consistent.

Every new year arrives with a familiar pressure: do more, change everything, fix the planet. And every year, many of us burn out before February. But what if 2026 didn’t begin with guilt, overwhelm, or unrealistic eco-resolutions ? What if it began quietly with awareness, intention, and small daily choices that actually stick? Mindful living isn’t about perfection. It’s not about zero waste overnight or owning a house full of bamboo products . It’s about paying attention to our habits, our impact, and our values and aligning them gently with the world we want to protect. A greener 2026 doesn’t need dramatic leaps. It needs consistency. What Mindful Living Really Means (and What It Doesn’t) Mindful living is often misunderstood as something slow, aesthetic, or reserved for people with unlimited time and resources. In reality, mindful living is simply intentional living. It means: Noticing before consuming. Pausing before wasting. Choosing with awareness, not impulse. It do...

LEAD POISONING

WHAT IS LEAD ? Lead(Pb) is a chemical element derived from the the Latin word plumbum, it has an atomic number of 82. It is a heavy metal which is denser than most common materials. Lead is soft and malleable, it also has a relatively low melting point of 600.61 K and low boiling point of 1749 °C. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number. OCCURRENCE OF LEAD IN NATURE Lead is found in nature, but rarely in pure form but in ores with other metals, meaning you can not find lead on it is own it is always found attached to other metals. — the most abundant one in the Earth's crust being galena (PbS). Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn). About 200 sites for solid lead are known worldwide as of 2017, some of this sites are in Argentina, Ethiopia, Australia, Belgium, Brazil, the Peopl...

Revolutionizing Food Preservation: How Melatonin and Nanotech Could Help Reduce Food Waste.

In a world where nearly one-third of all food produced is wasted often due to spoilage during storage and transport, scientists may have found a game changing solution. A new study published in Nano Letters introduces a sustainable, nature-inspired way to keep produce fresh without relying on energy-intensive refrigeration (Han et al., 2025). Researchers led by Yangyang Han and Benedetto Marelli have developed a nanotechnology-based delivery system that applies tiny, biodegradable carriers directly onto harvested crops. These carriers release melatonin, a naturally occurring plant compound, in precise doses to regulate ripening and delay spoilage. This method works within the plant itself (in planta), helping it manage oxidative stress and maintain postharvest health without altering its taste, nutrition, or safety profile. Most importantly, it does so outside the cold chain, offering a low energy alternative to refrigeration, especially critical in regions with limited inf...
