Dredging Activities And Public Health
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.

Empowering Youth Through Agriculture
Quote:”While job seeking youths should continuously acquire skills and explore opportunities within their immediate environment as well as in the global space through the use of digital platforms, government, corporate/ multinational organizations or the organised private sector should generate skills and provide the enabling environment for skills acquisition, through adequate funding and resettlement packages that will provide sustainable economic life for beneficiaries”.
The Governor of Rivers State, Sir Siminalayi Fubara, recently urged youths in the Rivers State to take advantage of the vast opportunities available to become employers of labour and contribute meaningfully to the growth and development of the State. Governor Fubara noted that global trends increasingly favour entrepreneurship and innovation, and said that youths in Rivers State must not be left behind in harnessing these opportunities. The Governor, represented by the Secretary to the State Government, Dr Benibo Anabraba, made this known while declaring open the 2026 Job Fair organised by the Rivers State Government in partnership with the Nigeria Employers’ Consultative Association (NECA) in Port Harcourt. The Governor acknowledged the responsibility of government to create jobs for its teeming youth population but noted that it is unrealistic to absorb all job seekers into the civil service.
“As a government, we recognise our duty to provide employment opportunities for our teeming youths. However, we also understand that not all youths can be accommodated within the civil service. This underscores the need to encourage entrepreneurship across diverse sectors and to partner with other stakeholders, including the youths themselves, so they can transition from being job seekers to employers of labour,” he said. It is necessary to State that Governor Fubara has not only stated the obvious but was committed to drive youth entrepreneurship towards their self-reliance and the economic development of the State It is not news that developed economies of the world are skilled driven economies. The private sector also remains the highest employer of labour in private sector driven or capitalist economy though it is also the responsibility of government to create job opportunities for the teeming unemployed youth population in Nigeria which has the highest youth unemployed population in the subSahara Africa.
The lack of job opportunities, caused partly by the Federal Government’s apathy to job creation, the lack of adequate supervision of job opportunities economic programmes, lack of employable skills by many youths in the country have conspired to heighten the attendant challenges of unemployment. The challenges which include, “Japa” syndrome (travelling abroad for greener pastures), that characterises the labour market and poses threat to the nation’s critical sector, especially the health and medical sector; astronomical increase in the crime rate and a loss of interest in education. While job seeking youths should continuously acquire skills and explore opportunities within their immediate environment as well as in the global space through the use of digital platforms, government, corporate/ multinational organizations or the organised private sector should generate skills and provide the enabling environment for skills acquisition, through adequate funding and resettlement packages that will provide sustainable economic life for beneficiaries.
While commending the Rivers State Government led by the People First Governor, Sir Siminilayi Fubara for initiating “various training and capacity-building programmes in areas such as ICT and artificial intelligence, oil and gas, maritime, and the blue economy, among others”, it is note-worthy that the labour market is dynamic and shaped by industry-specific demands, technological advancements, management practices and other emerging factors. So another sector the Federal, State and Local Governments should encourage youths to explore and harness the abounding potentials, in my considered view, is Agriculture. Agriculture remains a veritable solution to hunger, inflation, and food Insecurity that ravages the country. No doubt, the Nigeria’s arable landmass is grossly under-utilised and under-exploited.
In recent times, Nigerians have voiced their concerns about the persistent challenges of hunger, inflation, and the general increase in prices of goods and commodities. These issues not only affect the livelihoods of individuals and families but also pose significant threats to food security and economic stability in the country. The United Nations estimated that more than 25 million people in Nigeria could face food insecurity this year—a 47% increase from the 17 million people already at risk of going hungry, mainly due to ongoing insecurity, protracted conflicts, and rising food prices. An estimated two million children under five are likely to be pushed into acute malnutrition. (Reliefweb ,2023). In response, Nigeria declared a state of emergency on food insecurity, recognizing the urgent need to tackle food shortages, stabilize rising prices, and protect farmers facing violence from armed groups. However, without addressing the insecurity challenges, farmers will continue to struggle to feed their families and boost food production.
In addition, parts of northwest and northeast Nigeria have experienced changes in rainfall patterns making less water available for crop production. These climate change events have resulted in droughts and land degradations; presenting challenges for local communities and leading to significant impact on food security. In light of these daunting challenges, it is imperative to address the intricate interplay between insecurity and agricultural productivity. Nigeria can work toward ensuring food security, reducing poverty, and fostering sustainable economic growth in its vital agricultural sector. In this article, I suggest solutions that could enhance agricultural production and ensure that every state scales its agricultural production to a level where it can cater to 60% of the population.
This is feasible and achievable if government at all levels are intentional driving the development of the agricultural sector which was the major economic mainstay of the Country before the crude oil was struck in commercial quantity and consequently became the nation’s monolithic revenue source. Government should revive the moribund Graduate Farmers Scheme and the Rivers State School-to-Land agricultural programmes to operate concurrently with other skills acquisition and development programmes. There should be a consideration for investment in mechanized farming and arable land allocation. State and local governments should play a pivotal role in promoting mechanized farming and providing arable land for farming in communities. Additionally, allocating arable land enables small holder farmers to expand their operations and contribute to food security at the grassroots level.
Nigeria can unlock the potential of its agricultural sector to address the pressing needs of its population and achieve sustainable development. Policymakers and stakeholders must heed Akande’s recommendations and take decisive action to ensure a food-secure future for all Nigerians.
