Dredging Activities And Public Health

Published

2 years ago

on

Dredging involves in an excavation  operation usually carried out partly underwater, in shallow seas or fresh water areas with the purpose of gathering up bottom sediments and disposing them at a different location. On a positive side, dredging is often used to keep waterways navigable. Historically, the origins of dredging are lost in antiquity. The first known dredgers were the Phoenicians (modern day Lebanese) who created a worldwide network of ports, using stable ships to carry out dredging activities in rough waters. With modernisation, dredging became more technical and purposeful. For instance, in the United States, several hundred million cubic yards of sediment must be dredged from waterways and ports each year to improve and maintain the nation’s navigation system and to maintain coastal national defence readiness.
In Nigeria, the dredging of the River Niger many years ago was the first success recorded after which many registered and licensed companies most especially in the oil rich Niger Delta carried out dredging activities in that region. In 2009, Nigeria started a vast operation to dredge the River Niger to enable boats carry goods from the Atlantic Ocean to remote villages. The government said it would bring communities together, secure the flow to hydroelectric plants and ensure “all-year-round navigability”.
In considering the  rationale for dredging,  the negative effect should be considered first because the processes of eutrophication, sedimentation and pollution usually lead to collection and passage of rough, dirty and heavily polluted water and these in turn give rise to environmental health, social and economic concerns. Consequently, dredging activities are carried out to help to reduce aquatic vegetation growth by lowering the riverbed below photic zone (the depth of water in a lake, river, sea or ocean, which is exposed to sufficient sunlight to allow photosynthesis to take place). This, in turn, will help in dealing with nutrient loading, increase the habitat of fishes and reduce the breeding ground for mosquitoes. The resultant mortality, morbidity, damage to property and public infrastructure are pronounced.
The river transecting the community is now observed to be full of debris, with blocked channels, and plants grown on the surface and along the banks of the river. These could have caused obstruction to the flow of water and subsequent flooding. In addition, some residents are in the habit of dumping refuse at the riverbank, and some industries do discharge their agricultural products and wastes in water. This would automatically have influence on physical and chemical component of the river water, as well as deleterious effect on surrounding. Over the years, various levels of Government in Nigeria had embarked on dredging of the major rivers with a view to ‘sanitizing’ the environment. However, environmental impact assessment report before the exercise may not be publicly released, but the negative impact of dredging activities on health and environment cannot be over emphasised.
Some of these health and environmental effects should be taken into consideration before, during and after the dredging process. Dredging process has potentials for increased prevalence of communicable diseases. Because of the filthy environment brought about by unplanned disposal of dredged materials and indiscriminate refuse dumping at these sites, there could be an increase in the prevalence of communicable diseases. These refuse collections contaminate the surface soil and underground water, attract breeding of houseflies and act as sources of occurrences of diarrheal diseases such as Typhoid and Cholera. The waste heaps also serve as breeding sites for mosquitoes and consequently increase the prevalence of vector borne diseases.
Such breeding sites have both indirect and direct impact on the epidemiology of malaria in the city and the health systems, especially in local communities such as Aleto in Eleme Local Government Area, where dredging is going on. It would be noted that Eleme is a malaria endemic area in Rivers State and Nigeria at large. Though dredging brings about an improvement in flow of water and its speed, it may lead to subsidence increase and change in pattern of the epidemiology of diseases associated with fast flowing rivers such as onchocerciasis .In other words, the potential change in land cover and land use because of dredging brings about variety of global changes affecting ecological systems and 10 epidemiology of disease.
Inadequate dumping of excavated materials from dredged sites blocks most part of the waterways, rivers and streams in communities, including Aleto in Eleme Local Government Area. It is therefore, pertinent to put the necessary mitigating measures in place such as steps stipulated by Environmental Impact Assessment and engage in sustainable land use pattern to pollute less and conserve more of our environment towards sustainable growth. This would lead to a reduction in community health risks and enhance better quality of life. Although, dredging may have both negative and positive effects, the ill effects on health and environment are enormous if not properly managed. Dredging and disposal of contaminated sediment can adversely affect water quality, aquatic and terrestrial organisms.
In addition, dredging may damage underwater piping toxic chemicals that may have adverse effect on the aquatic lives content. Before any dredging activity is carried out in any environment, the government should endeavour to carry out a pre and post dredging environmental, and health impact assessment on a continuous basis, with reports of such assessments communicated to appropriate authorities. The prevalence of flooding in Aleto through Agbonchia communities in Eleme Local Government Area is a case in point. It becomes a cause for concern as some  indigenes of affected communities such as Aleto and Abonchia  are calling on the Rivers State Government to come to their aid to stop the illegal activities of dredging companies in the area. The situation in Okulu River in Aleto Community and Agbonchia is a case in point.
Reports say, affected communities have written to relevant agencies without any fruitful response. It is estimated that about 500 meters from Aleto Community to the Eleme Bridge on East West Road have 10 dredging machines and the noise pollution and vibration generated by these dredging machines are  injurious to the people leaving in the neighbourhood. It is common knowledge that residents in the entire area complain of adverse effects on their buildings. It is important to call on the authorities to check the menace and safeguard the lives before it becomes too late.
The time to act is now.

Monthly Environmental Sanitation Imperative 

Published

May 18, 2026

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.

God’s Intentionality in Ecological System

Published

Quote:”Every component of creation is interdependent, demonstrating that God designed nature as a balanced system in which each part contributes to the wellbeing of the whole”.
 
From the very first chapter of Scripture, the Bible presents a profound truth: creation was not accidental, random, or without meaning. The universe emerged from the deliberate counsel of an all-wise God who fashioned every aspect of life with purpose and precision. The heavens were stretched out by His command, the earth was carefully positioned, the seas were bounded, and every living creature was assigned a distinct role within a perfectly coordinated ecological system. When God surveyed His completed work, He pronounced it “very good,” affirming that creation was whole, harmonious, and exactly as He intended. The natural world remains a visible testimony to God’s intentionality. The sun provides warmth and energy at the right intensity to sustain life. The moon governs tides and seasons. Trees absorb carbon dioxide and release oxygen.
Rivers irrigate the land and quench thirst. Bees and butterflies pollinate crops. Birds disperse seeds. Animals maintain biodiversity. Every component of creation is interdependent, demonstrating that God designed nature as a balanced system in which each part contributes to the wellbeing of the whole. Nothing was made without significance, and nothing was left to chance. Among all created beings, humanity occupies a unique and privileged position. Unlike plants and animals, man was created in the image and likeness of God. This divine imprint endowed human beings with intelligence, moral consciousness, creativity, and the capacity for relationship with their maker. It also established mankind as the steward of creation. God granted humanity dominion over the earth, not as a license for reckless exploitation, but as a sacred trust to cultivate, protect, and preserve the world He had declared good.
Dominion, in God’s original intention, was to be exercised with wisdom, compassion, and responsibility. Human beings were meant to care for the land, use natural resources judiciously, and ensure that all forms of life flourished in accordance with divine order. The earth was to be managed as a trust from God, not plundered for selfish gain. Unfortunately, this divine mandate has been grossly misunderstood and widely abused. It is deeply regrettable that man has deviated so drastically from God’s original intention. Instead of stewardship, humanity has too often embraced greed. Instead of preservation, there has been exploitation. Instead of gratitude to the Creator, there has been reckless consumption and abuse of the environment. Across the world, forests are felled indiscriminately, rivers are contaminated, and fertile lands are stripped of their productivity.
 Species disappear as habitats are destroyed. Air pollution threatens public health, and climate change disrupts weather patterns and livelihoods. What God created as a life-supporting ecosystem is increasingly treated as a disposable commodity. In Nigeria, the consequences are especially painful. Oil spills in the Niger Delta have devastated farmlands, poisoned rivers, and destroyed fishing communities. Poor waste management clogs drains and contributes to flooding. Erosion eats away homes and roads. Illegal mining and logging scar the landscape. In many cases, communities suffer while those responsible evade justice. At the root of much of this destruction is corruption. Funds earmarked for environmental protection, sanitation, and erosion control are often diverted for personal enrichment. Regulatory agencies are compromised through bribery.
 Powerful individuals and corporations place profit above human welfare. Corruption thus becomes not only a moral failure but an assault on God’s creation. This environmental abuse is also a tragic expression of man’s inhumanity to man. When water is polluted, children fall sick. When farmlands are destroyed, farmers lose their means of survival. When rivers are contaminated, fishermen are plunged into poverty. When floods and erosion displace families, communities are torn apart. The burden of environmental degradation falls most heavily on the poor and vulnerable, while future generations inherit a diminished world. Yet, despite humanity’s failures, there remains hope for restoration. God’s purpose for creation has not changed. He still calls His people to responsible stewardship and righteous living. When individuals and nations return to God’s principles, they begin to view the earth not as an object to exploit, but as a sacred trust to preserve.
Responsible stewardship means protecting natural resources, planting trees, reducing pollution, disposing of waste properly, enforcing environmental laws, rejecting corruption, and treating others with justice and compassion. It requires governments to act with integrity, businesses to operate ethically, faith communities to teach creation care, and citizens to take personal responsibility for the environment. Creation care is therefore more than an environmental concern; it is a spiritual obligation. Our treatment of the earth and of one another reflects the sincerity of our reverence for God. To exploit nature, oppress the vulnerable, and enrich ourselves through corruption is to rebel against His purpose. To protect creation and uphold justice is to honor the Creator and participate in His original design. The world God made was declared “very good.” It is our solemn duty to ensure that our actions preserve rather than destroy that goodness.

Confronting National Development In Chinese Style

Published

1 week ago

Quote: “China’s rise was not a miracle. It was the result of deliberate planning, disciplined execution, and a national determination to make poverty reduction the foundation of national development.”
A short TikTok video by @ancientchinaforever recently offered a compelling summary of China’s remarkable transformation from one of the world’s poorest nations to a global economic powerhouse. In just a few minutes, it captured a lesson that developing countries like Nigeria cannot afford to ignore: meaningful development does not happen by chance. It is the product of vision, consistency, and a deliberate commitment to confronting poverty. In 1981, according to the World Bank, nearly 88 percent of China’s population lived in extreme poverty. The country was overwhelmingly rural, industrially weak, and lacking in modern infrastructure. Millions of people had limited access to quality healthcare, education, and basic social services. Yet China refused to accept poverty as its destiny. Its leaders made a strategic decision to treat poverty reduction as the starting point of national development.
 Rather than relying on slogans or isolated welfare programmes, they created a coordinated system that mobilised government institutions at every level toward one overriding goal: improving the living conditions of ordinary citizens.
This was the turning point in China’s history. Poverty alleviation became a national mission. Clear targets were established, responsibilities were assigned to provincial and local governments, and officials were evaluated based on measurable results. Data was used to identify poor households, monitor progress, and adjust strategies where necessary.In effect, China built what may be described as a national development machine.The first major reforms focused on agriculture. Through the household responsibility system, farmers were given greater control over their land and allowed to sell surplus produce after meeting government quotas.
 This policy created incentives for productivity and innovation. The results were dramatic. Agricultural output rose significantly, rural incomes increased, and millions were lifted out of poverty.With food security improving, China turned to industrialisation. The government established Special Economic Zones, most notably in Shenzhen, to attract foreign investment and promote export-driven manufacturing. What was once a small fishing community quickly transformed into one of the world’s leading industrial and technology hubs. Factories created millions of jobs, drawing workers from rural areas into expanding urban centres. China soon became the manufacturing capital of the world, producing electronics, textiles, machinery, and consumer goods for global markets.The revenue generated from industrial growth was reinvested in infrastructure and human development.
China understood that development requires more than factories. It demands modern infrastructure that connects people, goods, and markets. Massive investments were made in roads, railways, airports, seaports, electricity, and telecommunications.
Today, China’s high-speed rail system, modern cities, and efficient logistics networks stand as visible proof of decades of purposeful investment. Equally important was China’s commitment to education and healthcare.Schools were expanded, literacy improved, and vocational training equipped workers with the skills needed in a modern economy. Healthcare reforms reduced preventable diseases and protected families from being pushed deeper into poverty by medical costs.These investments ensured that economic growth translated into tangible improvements in living standards.
Another defining feature of China’s development model was policy continuity. Through successive Five-Year Plans, national priorities were clearly outlined and pursued over decades. While leaders changed, the core development agenda remained consistent. This stability encouraged investment, strengthened institutions, and allowed long-term projects to be completed. Unlike countries where each administration abandons the policies of its predecessor, China sustained a clear sense of direction.The results have been extraordinary. According to the World Bank, China has lifted more than 800 million people out of extreme poverty—the largest poverty reduction effort in human history. A broad middle class has emerged, and the country has become the world’s second-largest economy. Chinese companies such as Huawei Technologies and Alibaba Group now compete at the forefront of global innovation.
China’s journey has not been without challenges. Rapid industrialisation has contributed to environmental degradation, regional disparities, and demographic pressures. However, these challenges do not diminish the scale of its achievement. They underscore the complexity of transforming a nation of over one billion people. For Nigeria, China’s experience offers valuable lessons. First, poverty reduction must be treated as a strategic national priority rather than a campaign promise. Second, development requires long-term planning and policy continuity. Third, sustained investment in agriculture, infrastructure, education, and healthcare is essential. Fourth, institutions must be strengthened to ensure accountability and measurable outcomes. Finally, leadership must combine vision with disciplined execution. Nigeria is richly endowed with natural resources, entrepreneurial talent, and a youthful population.
What remains missing is a coherent and consistent development strategy that places national interest above politics. China’s transformation demonstrates that development is not a matter of luck. It is the outcome of clear priorities, effective institutions, and unwavering commitment. For countries still grappling with poverty and underdevelopment, China stands as compelling proof that when a nation confronts its challenges with strategic intent and collective discipline, extraordinary progress is possible.
