This paper argues that there is need for current efforts to reintegrate youth militants in the Niger Delta of Nigeria into normal community life to be anchored on a thorough understanding of the peculiar agency of youth and the socio-cultural challenges of post-conflict reintegration. Such efforts should also take cognisance of the complex nature of the problem. The paper contends that while the on-going amnesty programme in the region has achieved partial success, it was founded on a parochial philosophy, which creates a booming economic environment for the managers. Therefore, it recommends that the initiative should be anchored on both a thorough understanding of the youth as social agency and the deleterious impact of the conflict on ideal socio-cultural norms of expectations and roles among different generations of the population in the region. In effect, a proper sociological framing and nuancing of the programme would appear imperative for sustainable peace in the region. [ABSTRACT FROM AUTHOR]

International Oil Companies (IOCs) are increasingly becoming key development actors in communities where they operate. This is becoming the norm as IOCs come to the realisation that their contributions to the well-being of their host communities brings them closer to attaining their business goals. The evaluation of Corporate Social Responsibility (CSR) actions by IOCs operating in Nigeria's oil rich Niger Delta is however characterised by a unilateral self-assessment by IOCs themselves, without commensurate integration of host community participation. In providing an alternative approach, this study utilised a participatory community-based appraisal to evaluate the Shell Petroleum Development Company's (SPDC), Global Memorandum of Understanding (GMoU) model within the praxis of selected parameters for sustainable community development including ownership, participation, sustainability and transparency. The study argues that due to the limitations of universal indicators in the assessment of community development problems, a combination of community-based parameters works better in evaluating community development.

AbstractTo say that the Niger Delta literature or the poetics of extraction in the Delta has attracted numerous scholarly engagements is an understatement. However, most of the critical works written about the Niger Delta have been by male writers such as Gabriel Okara, Ken Saro-Wiwa, Tanure Ojaide, Ogaga Ifowodo, Nnimmo Bassey and others who are known for drawing attention to the environmental despoilment and the suffering of the various Indigenous communities of the Delta. In this article, I am interested in the framing of the Delta by female poets from the region. Building on Gayatri Spivak’s concept of the subaltern, I ask, are Niger Delta women writing? And if so, how do they contextualise women and nature in their poetic imagination? Mindful of the complexities in the region, what literary devices do they employ to aid their navigation of the murky confluence of state power, multinational corporations, and environmental degradation that abounds in the region unabated? This work applies the theoretical positions of ecofeminist scholars to the close reading of select poems from Sophia Obi’s Tears in a Basket (2005), Ekaete George’s Saints and Scoundrels (2018), and Iquo DianaAbasi’s Coming Undone as Stitches Tighten (2021).

The flaring of gas is a double jeopardy of wasting valuable energy resource and environmental degradation. That had been the experience with the Niger Delta area since 1956 when oil was discovered in commercial quantity in the region. Gas flaring is an active contributor of Green House Gases (GHG) emissions, global warming, climate change crisis and the consequent acid rain, rising temperature and sea level, flooding, agricultural and aquatic food chain disruption. The Niger Delta area as a global spot rich in oil, gas, aquatic and agricultural foods had remained a paradox of plenty, poverty and hunger. In view of this stack reality, it is the concern of this study to determine if zero hunger can be achieved in the area by 2030 and make recommendations that will serve as blue print for national and global actualization SDG 2. The study adopted documentary research method, leveraged on Public–Private Partnership (PPP) and Win–Win Concept as frameworks of interpretation and unveiled that ending gas flaring is associated with inherent economic growth, environmental preservation and sustainable livelihood in and beyond Niger Delta.

This study presents the findings of a comprehensive geotechnical and seismic site investigation conducted at Otuasega Town located in Bayelsa State within the Niger Delta region of Nigeria. Subsurface exploration involved advancing 10 boreholes to 30 m depth using hollow stem auger drilling. Continuous disturbed and undisturbed soil sampling was performed at 1.5 m intervals for detailed geotechnical testing. Laboratory tests on the recovered soil samples established the index properties, classification, densities and consistency limits of the stratified deposits. The subsurface profile comprised alternating layers of clay, silt and sand typical of deltaic sediments, with the clay fractions exhibiting medium to high plasticity. Shear wave velocity (Vs) profiling using Multichannel Analysis of Surface Waves (WASW) techniques categorised the site predominantly as Site Class C and D based on international standards. The Standard Penetration Test (SPT) N-values ranged from 5 to 10, indicating soft normally consolidated clay conditions typical of the Niger Delta region. Predictive empirical models developed from the field and lab data showed strong correlations for estimating key geotechnical parameters such as SPT blow count, Vs and liquefaction resistance. Ground response analyses using the Vs and SPT data indicated significant site amplification potential, with peak ground accelerations up to 1.5 times the bedrock motion. Liquefaction analysis based on the empirical SPT-based methods revealed a high potential for liquefaction in the sandy layers, especially under strong earthquake shaking. The study characterized the complex sedimentology and provided baseline information for seismic microzonation and site-specific ground response analyses to advance understanding of geohazards in this delta environment.

This study characterized the AA-01 depleted hydrocarbon reservoir in the KOKA field, Niger Delta, using a multidimensional approach. This investigation involved data validation analysis, evaluation of site suitability for CO2 storage, and compositional simulation of hydrocarbon components. The primary objective was to determine the initial components and behavior of the hydrocarbon system required to optimize the injection of CO2 and accompanying impurities, establishing a robust basis for subsequent sequestration efforts in the six wells in the depleted KOKA AA-01 reservoir. The process, simulated using industry software such as ECLIPSE, PVTi, SCAL, and Petrel, included a compositional fluid analysis to confirm the pressure volume temperature (PVT) hydrocarbon phases and components. This involved performing a material balance on the quality of the measured data and matching the initial reservoir pressure with the supplied data source. The compositional PVT analysis adopted the Peng–Robinson equation of state to model fluid flow in porous media and estimate the necessary number of phases and components to describe the system accurately. Results from this investigation indicate that the KOKA AA-01 reservoir is suitable for CO2 sequestration. This conclusion is based on the reservoir's good quality, evidenced by an average porosity of 0.21 and permeability of 1 111.0 mD, a measured lithological depth of 9 300 ft, and characteristic reservoir – seal properties correlated from well logs. The study confirmed that volumetric behavior predictions are directly linked to compositional behavior predictions, which are essential during reservoir initialization and data quality checks. Additionally, it highlighted that a safe design for CO2 storage relies on accurately representing multiphase behaviour across wide-ranging pressure–temperature–composition conditions.

Abstract The Onshore Hydrocarbon prospectivity of the Niger Delta X-field is examined through the integration of 3D seismic and recorded information from well log data. Probable reservoirs of hydrocarbon-bearing were delineated to tackle the non-uniqueness in the identification of hydrocarbon quantity of concern. Three significant faulting patterns or systems were delineated and their architectural attributes depict a typical Niger Delta embedded anticlinal structural pattern. The study field exhibited both synthetic and antithetic structures, hence only fault on delineated reservoirs was used for structural modeling. All well locations were sited within the fault-supported synthetic and anticlinal structures and the static characteristics within the well coordinates were analyzed through petrophysical assessment. Depicted reservoir sands show low gamma ray readings, low volume of shale, considerate hydrocarbon saturation and low water saturation. The established petrophysical models showed a better net-to-gross (NTG) ratio, for the entire delineated reservoir units. This has contributed to the assessment of hydrocarbon-bearing reservoir units before employing the strategy for field development scenario, in order to eliminate dry hole drilling campaign. These will contribute to the reduction of operational costs, having delineated the accurate geometry and petrophysical model of hydrocarbon reservoir units.

Abstract The Offshore Niger Delta, Nigeria, stands as a dynamic geological marvel, known for its intricate processes and extensive hydrocarbon reservoirs. This study employed an integrated approach, utilizing 3D seismic data and well logs, to conduct a thorough analysis of sequence stratigraphy and reservoir characterization in the pursuit of optimizing hydrocarbon exploration in the region. The study focused on the NW–SE trending Miocene depocenters, which predominantly comprises alternating sandstone and thick shale layers within the Agbada Formation. These reservoir units showcased stacked shallow marine fluvial–deltaic sediments, separated by significant marine shale units. Within the study area, two hydrocarbon-bearing reservoirs were identified and named: R1 and R2. Petrophysical analysis identified R2 as the most promising reservoir, with a permeability of 1184 × 10− 3 µm2, 85% hydrocarbon saturation, porosity of 0.30, and effective porosity of 0.27. Fault structural analysis uncovered that hydrocarbons are trapped within a network of growth faults within the wave-dominated Niger Delta depositional system. From the sequence stratigraphic interpretation, four depositional sequences were delineated between the depths of 2030–3417 m, and are bounded by five sequence boundaries. Integrated seismic facies analysis revealed high-energy feeder systems likely supplying sediments from river sources to offshore locations. These integrated findings provide essential insights to inform resource management, exploration strategies, understanding of reservoir distribution, and structural intricacies within the complex offshore Niger Delta, Nigeria, providing valuable information. The depositional environment helped in the understanding of the stratigraphic traps which are prospects in the study area. This together with the associated reservoir quality allowed accurate prediction for potential reservoir facies and will further improve the field development plans.

ABSTRACTThe Unumherin community in Nigeria’s Niger Delta is home to coastal marine polluted zones, and this research examines the radioactivity distributions and biohazard in the coastal environment. The activity concentrations of 40K, 238U, 232Th, as well as the outdoor dose rate of contaminated coastlines were measured using a calibrated RS-125 Gamma-Spec and a NaI(Tl) gamma-detector. The laboratory examination of sediments, water, and fish from the same coastal region – Clarias gariepinus Pseudotropheus elongated Oreochromis niloticus and Stromateus fiatola – was combined with the in-situ observations of gamma dose rates. With a value of [Formula: see text], the hotspot at site 4 is shown by the geographic distribution of gamma dose rates. The findings showed that the activities of the primordial radionuclides varied, with average values for the sediments and water exceeding suggested limits. Similarly, the corresponding mean hazard indices mostly exceeds the allowable limits. The species specificity of the fish species accounts for the variation in the mean concentrations of 40K, 238U and 232Th. C. gariepinus, having accumulated higher concentrations of 40K and 238U, may be the first to elicit health hazards in the future if pollution continues unmonitored. Hence, continuous monitoring of the aquatic environment alongside is highly recommended.

Background: Regular and periodic assessment of pattern of childhood mortality in the Children emergency room (CHER) is important to define common childhood killer diseases, notify responsible authorities and outline measures to prevent and curb them. Objectives: The aim of this study was to describe the pattern of childhood mortality seen in the CHER of a tertiary centre in the Niger Delta region- Bayelsa State of Nigeria over a 5 year period (1st January 2014 to 31st December 2018) Methods: The admission records of all the children admitted into the CHER of the Department of Paediatrics of the Niger Delta University Teaching Hospital (NDUTH), Bayelsa State were retrospectively reviewed and analysed. Results: One hundred and thirty nine out of 1,949 children admitted over the study period died, giving a mortality rate of 7.1%.Out of 139 children who died, 88 (63.3%) of them died within 24 hours of arrival at the hospital. Majority of the deaths, 115 (82.7%) were children under the age of 5 years out of which 51.3% were infants. The common causes of death were septicaemia (34.8%) and severe malaria (34.8%) among the under-fives and meningitis (25.0%) and HIV/ TB (20.8%) among those above the age of 5 years. The highest number of mortalities were recorded in the months of February to April and there was a decline in annual mortality rates over the five year period however, this was not statistically significant. Conclusions: Childhood mortality is high in Bayelsa State especially among the under-fives. Most of the deaths are preventable. Strengthening of the existing programmes such as malaria control practices, good antenatal care, training and retraining of health workers, extension of immunization services beyond infancy and good access to health care services is advocated to reduce Childhood mortality

Abstract This study assessed soil pollution and index properties in Okpulor through geochemical, geotechnical, and geoenvironmental analyses. Twenty samples, comprising 14 surface and 6 shallow subsurface ones, underwent geochemical analysis for heavy metals (Fe, Cr, Cu, Zn, Ni, and Pb). Five geochemical indices, including the Geoaccumulation Index (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Metal Pollution Index (MPI), and Potential Ecological Risk Index (PERI), were utilized. Simultaneously, six subsurface samples underwent geotechnical analysis for Natural Moisture, Grain Size, Specific Gravity, Bulk Density, and Atterberg Limits, following Unified Soil Classification System (USCS) and American Association of State Highway and Transportation Officials (AASHTO) guidelines. The Igeo highlighted significant heavy metal contamination in Okpulor soils, particularly Cd. EF values exceeding 1.5 underscored a strong anthropogenic influence, with CF indicating Cd's substantial contribution to overall contamination. PERI underscored the ecological risks associated with Cd contamination. Natural moisture content, ranging from 18.21% to 21.45%, indicated a notable presence of water in the soil during the dry season, potentially leading to increased leaching and migration of water-soluble contaminants. Bulk density values suggested moderate to lightly packed soils, impacting porosity and permeability, and influencing contaminant movement. Atterberg limits indicated low soil plasticity, impacting moisture retention and contaminant behaviour. Grain size analysis revealed poorly graded soils with a close sand-to-clay ratio, affecting water drainage. These geotechnical properties and heavy metal contamination reveal the intricate interplay between soil characteristics and contamination risks in the Okpulor area, emphasizing the need for targeted interventions to safeguard the environment.

Piracy cannot be understood in isolation from other (criminal) engagements, but how can we explore such linkages and why is it relevant to understand their implications, both for piracy and counterpiracy? Appreciating that Niger Delta-based piracy has dropped to historically low levels, this article explores what pirates do when they do not sustain themselves by engaging in piracy. As such, the article offers novel empirical insights into underexplored dimensions of piracy. Moreover, we use this case-study to demonstrate the relevance of an infrastructure-inspired conceptualization much beyond analyses of piracy and counterpiracy. Showing how piracy is linked to broader and often violent infrastructures that interventions leave unaddressed, and stressing key implications of the continuity and change in such linkages, is a first step towards appreciating the centrality of a broader dilemma that intervention actors confront: how to conceptualize the necessity to delimit a problem, while appreciating the significance of problem-dimensions left unaddressed? Our suggestion is that an infrastructure-inspired approach offers a helpful starting-point, a suggestion that we demonstrate in an analysis of how Niger Delta-based piracy forms part of a broader 'gun business' landscape, which does not only entail different types of crime but also various types of victims.

The study investigated heavy metal residues and bacterial pathogens in blue crab (Callinectes amnicola), crayfish (Nematopaelemon hastatus), giant tiger prawn (Penaeus monodon), and Indian prawn (Fenneropenaeus indicus) from crude oil impacted Niger Delta waters. Standard methods of analysis were applied in all determinations. Results indicate that chromium, lead, and mercury were within regulatory acceptable levels. Total viable count (TVC) was below threshold, while Vibrio cholerae, Vibrio parahaemolyticus, and Salmonella typhimurium were isolated from all crustacean species. The distribution pattern of pathogens showed blue crab accumulated the highest population of pathogens. Consumption of crustaceans from the location exemplifies conflict of nutrient benefits and risks. [ABSTRACT FROM AUTHOR]

Geochemical and biomarker characteristics of representative crude oil samples from selected fields in southern Nigeria were evaluated to determine the organic matter input, origin of biological material, depositional environment, thermal maturity, and genetic relationship between the oils. Four crude oil samples were obtained from various oil producing fields from Delta, Bayelsa and Abia state in southern Nigeria and labeled Kwale (KW), Kolo creek (KLC), Owaza (OWA1 and OWA2). The crude oil samples were fractionated into saturates, aromatic hydrocarbons and polar compounds using column chromatography on silica gel thereafter, analyzed using Gas chromatography-mass spectrometry (GC–MS). The calculated ratios of normal alkanes, acyclic isoprenoids, carbon preference index (CPI), hopanes, and steranes showed the following results: Pr/Ph (0.34 to 0.89); C29/C27 (0.78 to 1.25); 20S/(20S + 20R)C29sterane (0.28 to 0.66); 22S/(22S + 22R)C32 homohopane (0.17 to 0.23); CPI (0.96 to 0.98); Ts/Ts + Tm (0.46 to 0.50); and sterane/hopane (0.16 to 0.87). The results obtained were used to correlate the crude oils with respect to depositional environment, thermal maturity, and organic matter source. The Pr/Ph ratios of KW and KLC were less than one, and the cross-plot of Pr/nC17 versus Ph/nC18 of KW and KLC suggested that the oils were deposited under anoxic environments, whereas OWA1 and OWA2 indicated oxic conditions with no biodegradation. From the calculated ratios of 22S (22S + 22R)C32 homohopane and CPI, the oils were mature and had entered the generating window. Sample OWA1 is the most mature, while KLC is the least mature. The calculated ratios also showed that the four oil samples were from a shale source rock with both terrestrial and marine inputs. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to examine the relationship between pollution and life expectancy in oil producing communities, where there is a dearth of empirical evidence on how knowledge and coping strategy, agriculture and foreign capital inflows mediate the relationship between pollution and life expectancy. Design/methodology/approach: The study employed a cross sectional survey design to analyze the roles of knowledge and coping strategy, agriculture and foreign capital inflows in the relationship between pollution and life expectancy in Benekuku and Okpai oil producing communities in the Niger Delta. The study employed the modern structural equation modeling (SEM) estimator. Findings: Estimates show the mediating effect of agriculture on air pollution-longevity (coeff. = 0.398; t-value = 4.425; p < 0.05) and (coeff. = −0.120; t-value = −3.862; p < 0.05) mediating effect of foreign capital. The result revealed that agriculture and foreign capital inflows are significant mediators in pollution-life expectancy relations, affirming the Niger Delta as a pollution haven. However, knowledge and coping strategy with estimate of (coeff. = 0.233; t-value = 6.150; p < 0.05) spurs life expectancy. Practical implications: The study suggests knowledge of hazard identification and reporting and awareness of coping strategy as the panacea to poor life expectancy rate in these local oil producing communities. Originality/value: The study departs from existing works by estimating the mediating roles of agriculture and foreign capital inflow in air pollution-Life expectancy by controlling for knowledge and coping strategy using the structural equation model with ethical approval from Health Ethics Research Committee.

Information on associated gas flaring in the Niger Delta is analyzed to characterize the various stages in the lifecycle of an oil exploration and production facility through which gas flaring is introduced into an area, leading to ecological, health, and economic impacts, and possible policies and implementation strategies for the reduction of the flared gas are offered. Gas flaring is currently occurring at a rate of 5318 million m3 per year in the Niger Delta region. The impacts of gas flaring on the ecological, human, and economic systems include poor air quality, acid rain, and soil degradation. Other impacts include decreased crop yield, increased incidences of respiratory diseases amongst inhabitants in the area, and losses of billions of USD yearly in economic costs. Three dominant stages in the introduction of gas flaring are characterized in this study, using the concept of the management of the invasion of non-native species into an ecosystem and it is determined that the cheapest method of minimizing gas flaring is to incorporate mitigation measures during the design stage of the oil exploration/production facility, rather than after flaring has commenced, as is the common emphasis. During the early periods of oil production, gas flaring is largely localized, and the gas utilization measures can still be implemented to good effect. However, once the facility is established, gas flaring becomes pervasive, stretching kilometers beyond the flare points. Current policies like the imposition of flare-out years on the oil producers have helped, but they have been insufficient as the intensity of gas flaring in the region continues at double the average global levels. Working with relevant stakeholders, a realistic flare-out deadline should be agreed upon, clear and specific gas flaring legislation should be drawn up that includes measures to mitigate gas flaring for each proposed oil facility, and proper data collection and management services would enable the implementation of the policies to be based on robust evidence. These policies would shift the costs of gas flaring away from the inhabitants of the region back to the operators of the facilities that are the sources of the flares. [ABSTRACT FROM AUTHOR]

Oil spills in the Niger Delta could exert environmental pressures on the soil component. We investigated the impacts of oil spills and the effect of the Enhanced Natural Attenuation (ENA) remediation method on contaminated soil and resident microbial populations in the Odhiaje community in Rivers State, Nigeria. Soil samples for microbiological studies were collected weekly during a 17-week remediation period, while those for edaphic parameters were taken before and after remediation, all at 4 sampling points (SPs). Serial dilution of the oil-impacted soils for microbial density enumeration was carried out according to standard methods. Results revealed that mean concentrations of Total Petroleum Hydrocarbon Contents (THC) (Sig.value = 0.009), SO42- ions (Sig.value = 0.001), and sand compositions (Sig.value = 0.045) all differed markedly across the sampling points at p<0.05. Mean levels of EC (Sig.tvalue = 0.039) and ΣN (Sig.tvalue = 0.058) & K+ ions (Sig.tvalue = 0.004) differed significantly before and after the remediation exercise at the 95% confidence interval. Application of nutrients was rapidly accompanied by microbial population increases, leading to the consumption of oil contaminants in soils to levels comparable to control over the remediation period. Total Heterotrophic Bacteria counts correlated with pH (r = 0.501) and SO42- ions (r = 0.500) (p<0.05), and K+ ions (r = -0.800) (p<0.01); Total Heterotrophic Fungi correlated with pH (r = 0.520) (p<0.05), and Mg2+ ions (r = 0.820) (p<0.01); Hydrocarbon Utilizing Bacteria correlated with available P (r = 0.530) and silt composition (r = -0.504) (p<0.05), and K+ (r = 0.626) and Mg2+ ions (r = 0.733) (p<0.01); and Hydrocarbon Utilizing Fungi correlated with K+ (r = 0.500) & Mg2+ ions (r = 0.506) (p<0.05). Results indicate improvement in C/N ratios and effectiveness of the current cost-effective bioaugmentation technique in the restoration of arable soil productivity in the Odhiaje community.

Impacts of structuration on the geomorphology and internal architecture of a Pleistocene feeder channel-ponded lobe system, Channel-1B (Ch-1B), on the continental slope of the Niger Delta, Nigeria, has been studied using a combination of 3D seismic stratigraphy and geomorphology methods. Mapping of diagnostic seismic facies, characterization of channel morphology and internal architecture, quantitative analysis, architectural element (AE) delineation, and reservoir modeling were carried out with the view to (1) establish Ch-1B geomorphology, internal architecture, and sediment fills, (2) investigate the influence of structuration on the evolution of internal architecture over time, and (3) assess the impact of the resulting internal architecture variability on reservoir modeling and development strategies. This study established a strong link between structuration and the evolution of feeder channel-ponded lobe systems. Evolution of Ch-1B has been summarized in five phases: (I) channel initiation dominated by sediment bypass and incision into fold-1, (II) major break in slope gradient resulting in deposition of ponded lobe-1, (III) complete fill of accommodation created in the ponded basin between folds 1 and 2, diversion of the channel axis westward by fold-2 and eventual incision into lobe-1 and fold-2 by the feeder channel as it adjusted to a new base level, (IV) deposition of lobe-2 in the footwall of fold-2, and (V) filling of the feeder channel, almost entirely, by turbidite muds thereby creating a channel plug that partitioned lobe-1 into two compartments. Understandings, from this work, of the impacts of structuration on geomorphology and internal architecture have been applied to AE delineation, reservoir modeling, and development strategies in terms of the number and type of wells needed to produce hydrocarbon in lobe-1 efficiently. Given that well costs represent a significant portion of field development costs, this study concludes that adequately delineating and modeling structurally influenced AEs will significantly affect field development economics.

The Niger Delta in Nigeria is a complex and heavily contaminated area with over 150,000 interconnected contaminated sites. This intricate issue is compounded by the region's strong hydrological processes and high-energy environment, necessitating a science-based approach for effective contamination assessment and management. This study introduces the concept of sub-catchment contamination assessment and management, providing an overarching perspective rather than addressing each site individually. A description of the sub-catchment delineation process using the digital elevation model data from an impacted area within the Delta is provided. Additionally, the contamination status from the delineated sub-catchment is reported. Sediment, surface water and groundwater samples from the sub-catchment were analyzed for total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs), respectively. Surface sediment TPH concentrations ranged from 129 to 20,600 mg/kg, with subsurface (2-m depth) concentrations from 15.5 to 729 mg/kg. PAHs in surface and subsurface sediment reached 9.55 mg/kg and 0.46 mg/kg, respectively. Surface water exhibited TPH concentrations from 10 to 620 mg/L, while PAHs ranged from below detection limits to 1 mg/L. Groundwater TPH concentrations spanned 3 to 473 mg/L, with total PAHs varying from below detection limits to 0.28 mg/L. These elevated TPH and PAH levels indicate extensive petroleum contamination in the investigated sediment and water environment. Along with severe impacts on large areas of mangroves and wetlands, comparison of TPH and PAH concentrations with sediment and water quality criteria found 54 to 100% of stations demonstrated exceedances, suggesting adverse biological effects on aquatic and sediment biota are likely occurring.

Despite its potential for economic growth and sustainable development, Nigeria faces social challenges including poverty, environmental degradation, and economic decline. In 2023, it ranked 146th out of 166 on the SDG index, with a poverty headcount of $2.15/day. Over the past two decades, Nigerian oil and gas companies have faced sustainability criticism, emphasizing the importance of CSR initiatives for triple bottom line sustainability. This study examines how the CSR initiatives of Nigerian energy companies impact the sustainability and resilience of the Niger Delta region. By using an explorative research design guided by positivism philosophy, 460 survey responses were collected from Niger Delta community members via Google Form and analyzed using PLS-SEM since the research framework of the CSR and COM-R model comprises five primary dimensions each. The study discovered that CSR initiatives have a significant impact on sustainability and resilience in the Niger Delta. This underscores that integrating socially responsible initiatives not only enhances the ethical standing of these businesses but also generates high strategic value, bolstering their sustainability and resilience. The research recommendations include reassessing CSR initiatives, increasing community engagement, and collaborating with regulatory bodies. This will foster community cohesion, adaptability, and voluntary compliance with industry standards and social norms within the community. The research's descriptive value lies in its empirical demonstration of the connection between CSR and sustainability resilience. Firms can use these findings to enhance their CSR efforts and improve sustainability and resilience in future business practices. The research acknowledges potential biases in data collection stemming from unequal online access among the members of Niger Delta communities, resulting in a partial representation of the diverse range of respondent behaviours across the continent, as various cultural, economic, and social factors can influence their survey responses.

Abstract Geochemical and biomarker characteristics of representative crude oil samples from selected fields in southern Nigeria were evaluated to determine the organic matter input, origin of biological material, depositional environment, thermal maturity, and genetic relationship between the oils. Four crude oil samples were obtained from various oil producing fields from Delta, Bayelsa and Abia state in southern Nigeria and labeled Kwale (KW), Kolo creek (KLC), Owaza (OWA1 and OWA2). The crude oil samples were fractionated into saturates, aromatic hydrocarbons and polar compounds using column chromatography on silica gel thereafter, analyzed using Gas chromatography-mass spectrometry (GC–MS). The calculated ratios of normal alkanes, acyclic isoprenoids, carbon preference index (CPI), hopanes, and steranes showed the following results: Pr/Ph (0.34 to 0.89); C29/C27 (0.78 to 1.25); 20S/(20S + 20R)C29sterane (0.28 to 0.66); 22S/(22S + 22R)C32 homohopane (0.17 to 0.23); CPI (0.96 to 0.98); Ts/Ts + Tm (0.46 to 0.50); and sterane/hopane (0.16 to 0.87). The results obtained were used to correlate the crude oils with respect to depositional environment, thermal maturity, and organic matter source. The Pr/Ph ratios of KW and KLC were less than one, and the cross-plot of Pr/nC17 versus Ph/nC18 of KW and KLC suggested that the oils were deposited under anoxic environments, whereas OWA1 and OWA2 indicated oxic conditions with no biodegradation. From the calculated ratios of 22S (22S + 22R)C32 homohopane and CPI, the oils were mature and had entered the generating window. Sample OWA1 is the most mature, while KLC is the least mature. The calculated ratios also showed that the four oil samples were from a shale source rock with both terrestrial and marine inputs.

This work studied Romans 8:19-22 with a focus on the frustration human actions bring to the non-material creation which makes it yearn to be liberated from them and tries to see its relationship to the ecological devastation in the Niger Delta, Nigeria. Using the historical-critical method of exegesis and comparative and contextual methods it maintains that there is a relationship between the image of creation painted in Rom 8:19-22 and the ecological situation in the Niger Delta. It holds that since humans played a major role in rendering the non-material creation incapable of realising its natural goal, humans also have a role to play in its restoration. It further states that since humanity through the Christ event has been reconciled to God and looks forward to the realisation of the fullness of such reconciliation, reconciled humans should relate to the rest of creation in such a way that it will also experience the effect of this reconciliation as it awaits its fullness in future. The paper contributes to the discussion on environmental realised eschatology.

The presence of water in the natural gas stream could cause pipeline corrosion, limit pipeline flow capacities, pipeline blockages and possible damage to process filters, valves, and compressors. The absorption gas dehydration system with Triethylene Glycol (TEG) as an inhibitor is the most widely used and reliable gas dehydration system for non-cryogenic pipeline operation. TEG losses have been a serious concern to the operation personnel in “X” dehydration Plant in the Niger Delta region of Nigeria. This study therefore presents the economic analyses of gas dehydration by the introduction of a stripping (sales) gas to the TEG regenerator-reboiler to enhance the vapor separation and scrub off any gaseous impurities that may still exist in the rich TEG. The existing dehydration units were modeled and process parameters were simulated using Aspen HYSYS® software. An instance from the simulation results shows that, for a TEG flow rate of 0.4543 m3/h, 97% of TEG was recovered. However, with the introduction of a dry natural gas to the reboiler, 99.98% of the TEG was recovered. This significant improvement, which represents 10.2 kg/h of TEG recovery, translates to a cost saving of approximately $89,352 per year.

Oil spills in resource-rich areas in Africa have led to irreversible environmental degradation, resulting in social conflicts that have greatly affected women. Yet, the experiences of ordinary women affected by resource extraction activities in the Global South are often marginalised. Recent calls for the southernising of criminology are gaining momentum and could be linked to calls for rethinking how knowledge about Africa is produced, including in its gendered dimensions. For example, in what ways do women’s voices matter on issues related to the environment in the Niger Delta? And how do their voices intersect with green criminological theories? This article focuses on amplifying affected women’s lived experiences in the resource-rich area of the Niger Delta of Nigeria. Using data collected between 2019 and 2022 through participatory video, focus group discussions, and in-depth interviews, the paper underscores the need to give women a voice on matters that affect the environment, and peace and war dynamics.

The Niger Delta environment is under serious threat due to heavy metal pollution. Many studies have been conducted on the heavy metal contamination in soils, water, seafood and plants in the Niger Delta ecosystem. However, there is a lack of clear understanding of the health consequences for people and strategies for attaining One Health, and a dispersion of information that is accessible. The study focused on investigating the contamination levels, distributions, risks, sources and impacts of heavy metals in selected regions of the Niger Delta. Prior studies revealed that the levels of certain heavy metals, including Cd, Pb, Cu, Cr, Mn, Fe and Ni, in water, sediment, fish and plants in most Niger Delta ecosystems were higher than the acceptable threshold attributed to various anthropogenic stressors. In the reviewed Niger Delta states, ecosystems in Rivers state showed the highest concentrations of heavy metals in most sampled sites. Groundwater quality was recorded at concentrations higher than 0.3 mg/L World Health Organization drinking water guideline. High concentrations of copper (147.915 mg/L) and zinc (10.878 mg/L) were found in Rivers State. The heavy metals concentrations were greater in bottom-dwelling organisms such as bivalves, gastropods and shrimp than in other fishery species. Heavy metal exposure in the region poses risks of communicable and non-communicable diseases. Diverse remediation methods are crucial to reduce contamination levels, but comprehensive strategies and international cooperation are essential to address the health hazards. Actively reducing heavy metals in the environment can achieve One Health objectives and mitigate disease and economic burdens. [ABSTRACT FROM AUTHOR]

This article focuses on the constitutive elements of Nigeria's sovereignty. Its opposing dynamics are the definitional and contextual problems that lace the concept as revealed by the extant literature on sovereignty. The article argues that the tendency of the Nigerian state to exert full sovereignty through overcentralization is the heart of the resistance/militancy in the Niger-Delta, which has taken the dimension of armed conflict. The resistance, it further argues, has undermined the country's sovereignty by its capacity to weaken oil exploration in the region and the resultant short-fall in revenue accruing to the central government. In addition, the consequent meddlesomeness in the crisis by foreign actors imposes a negative sovereignty on the country. In conclusion, the paper calls for autonomous regions that are vested with the power over their resources. This can be achieved through a Sovereign National Conference. [ABSTRACT FROM AUTHOR]

This paper investigated selected physiognomies of crude oil and petroleum products collected from Kali in Delta State, Kula in Rivers State, and Nembe in Bayelsa State in the Niger Delta Region of Nigeria using the standard procedure of the American Society for Testing and Materials (ASTM). The result shows that the crude oils were different in terms of API gravity and specific gravity. API gravity of 52.17, 46.31, and 45.38 for Kwale, Kula, and Nembe respectively. This shows that they are not heavy crude oil. The low water content and low viscosity of the crude oils lower the risk of pipe and container corrosion and flow difficulty. The result of density, specific gravity, viscosity, and kinematic viscosity shows the value of those parameters increase from light fraction to heavy fraction. The pour point and flash point recorded for light fractions were lowered than that of heavy fractions, for the three samples of crude oil. The flash point is 61.3° C, -34° C, and -31° C while the pour point is 9 ° C, 2° C, and 6 ° C respectively for Kwale, Kula, and Nembe. The level of heavy metal analyzed was generally low but metals such as nickel and vanadium and other elements such as Nitrogen, Oxygen, and Sulphur were in abundance in the samples of the crude oil. The results are discussed in terms of importance and implication. [ABSTRACT FROM AUTHOR]

For sometime now, there has been a conversation among scholars about male hegemony in African popular music and how some women performers resist the established status quo. In joining the discourse in this article, I focus on the owigiri music of Diepreye Osi, a female bandleader among the Ịjọ of Nigeria's Niger Delta region. With particular attention to the departments in the bands of that premier neo-traditional music in the Ịjọ community, including instrumentation, dancing and singing, I argue that Diepreye contests patriarchy in her musical ensemble. Data for the study was gathered from unstructured interviews of artists and non-artists, and observation of live performances. [ABSTRACT FROM AUTHOR]

Performing reservoir characterization in exploration with limited data can be very is challenging. Various approaches are used to estimate values away from the well location. In this study, the density log, which is important for porosity analysis, was missed in one of the five available well log datasets. To solve this problem, an artificial neural network (ANN) approach was used to synthesise a density log (RHOB) from available and measured Gamma Ray (GR) log, Sonic (DT), water saturation (SW), and related Depth of 3 wells in the field. The performance of the prediction was evaluated using the fourth well. Five models were constructed with different optimizers from machine learning with a neural network made of an input layer with 5 neurons, a hidden dense layer with 32 neurons and an output dense layer with 1 neuron. The models were constructed based on Nesterov-accelerated Adaptive Moment Estimation (NADAM), Adaptive Moment Estimation (ADAM), Stochastic Gradient Descent (SGD), and Root Mean Square Propagation (RMSP) optimizers, and an Ensemble model which combined the four optimizers. The test on actual data showed very low mean absolute errors of 0.0262, 0.0278, 0.0270, 0.0309, and 0.0248 and high coefficients of determination (R2) of 0.8832, 0.8746, 0.8986, 0.8858, and 0.9051 between the predicted and the actual data obtained for NADAM, ADAM, SGD, RMSP, and the Ensemble model, respectively, after 25 epochs. These indicated high performance of the Ensemble Learning model, suggesting that the constructed model can be used to predict the well that lacks RHOB.

Abstract Invasive species are a leading threat to biodiversity worldwide. Nypa palm (Nypa fruticans) has emerged as the predominant invasive species in the Niger Delta region of Nigeria. While endemic mangroves have high rates of carbon sequestration, stabilize coastlines and protect biodiversity, Nypa does not provide these services outside its native region of Southeast Asia. Oil exploration and urbanization in this region also exacerbate mangrove loss and Nypa spread. As Nypa is difficult to distinguish from endemic mangrove species in remotely sensed data, estimates of mangrove and ecosystem services losses in Nigeria are highly uncertain. Here, we analyse multisensor satellite data with machine learning to quantify the rapid expansion of Nypa from 2015 to 2020 in Nigeria. Using Landsat imagery and random forest classification, we quantify total potential Nypa extent in Nigeria in 2019. We then produced a Nypa extent map using iterative combinations of Sentinel‐1 SAR, Sentinel‐2 MSI and ALOS PALSAR. Random forest classifications using SAR data from ALOS and Sentinel‐1 were best suited for mapping Nypa extent with similar accuracies (78% and 75%, respectively). Based on data availability and accuracy, we focussed our change analysis on Sentinel‐1 SAR. Our results show ~28 000 ha of mangroves were converted to Nypa in Nigeria by 2020 and covered a larger extent than endemic mangroves, compounding the effect of the existing degradation and deforestation in the region. We also compared forest height and complexity estimates from Global Ecosystem Dynamics Investigation LiDAR to further distinguish between endemic mangroves and Nypa in three dimensions. Nypa structural variability, measured by top‐of‐canopy height, vegetation cover, plant area index, and foliage height diversity, was lower than that of mangroves. At current rates of Nypa expansion, the entire area of study would be invaded by Nypa by 2028, with potentially detrimental consequences to the ecosystem services provided by mangroves.

Fine and coarse typical sand are among the most vital raw materials in building construction. A lot of drilling has been done without appropriate subsurface information resulting to a waste of resources and time. Geophysical methods give information on subsurface lithologies to locate areas with huge success. Thus, a geophysical investigation of subsurface deposits was carried out in this research to ascertain the quantity of fine/Coarse sand or areas with viable fine/Coarse sand utilizing Schlumberger configuration, Dipole–Dipole (2D) and well logging in parts of Okpe and Ughelli North LGA of Delta State, Nigeria, before extraction (dredging) for the benefit of exploitation and development. This was done by assessing the geo-electric formation of fine/coarse sand in the studied areas concerning their depths and thicknesses. Seven Vertical Electrical Sounding (VES) were obtained with the application of Schlumberger array, seven 2D and three well logging to estimate the viability of sand deposits in the study areas. These techniques have the efficacy of detecting near-bed formation with vital resolution. The data obtained from the field were illustrated by partial curve matching coupled with computer iteration using the WIN RESIST and Dipro Software to obtain sounding curves which revealed four to six layers. The layers consist of topsoil, lateritic clay and clayey sand, fine sand deposit, medium to coarse grain sand and coarse sand. For Agbarho, thicknesses of fine/coarse sand in the VES stations ranges from 18.0 to 55.6 m with resistivity varying from 223.7 to 572.9 Ωm, Osubi Fine/Coarse sand thickness ranges from 13.5 to 59.9 m with resistivity values within 211.9–891.0 Ωm and Oha town locations have fine/coarse sand thickness varied from 46.6 to 83.7 m with resistivity interval computed between 145.9 Ω-m and 466.4 Ω-m. Thus, the best VES stations that are more viable for sand mining are VES 1, 5 and 7 which contain relatively huge viable sand deposits in the study areas to a depth above 80 m.

This study aims at computing the pooled mean estimate (PME) and health risks of heavy metals in seafood obtained from the Niger Delta Region of Nigeria (NDRN), using data from existing literatures. Pubmed, Scopus and Google Scholar were searched to retrieve articles that investigated the heavy metal contents of edible seafood from the NDRN. Search hits were screened against predetermined criteria following which relevant data were extracted from eligible articles. The PME for each metal was computed by performing a maximum likelihood random effect model meta-analysis using the R Studio Software. Outcome from the meta-analysis involving 58 studies and a total of 2983 seafood samples revealed the following PMEs (mg/kg dry wt seafood) for the investigated heavy metals: As (0.777), Cd (0.985), Co (4.039), Cr (2.26), Cu (11.45), Fe (143.39), Hg (0.0058), Mn (13.56), Ni (5.26), Pb (4.35), and Zn (29.32). The health risk assessment suggests that seafood from this region poses considerable carcinogenic and non-carcinogenic risks to human consumers. Our finding calls for urgent actions aimed at identifying and eliminating point sources of heavy metals pollution of the NDRN marine environment. Inhabitants of NDRN are encouraged to reduce seafood consumption while diversifying their protein sources to include non-seafood options.

Scholarship that has studied the #EndSARS movement in Nigeria remains scanty. In contributing to debates surrounding the #EndSARS movement, we focus on the Niger Delta region and the effect of the movement on the people. Online interview of 20 participants across the region, reports from Amnesty International, the Human Rights Watch and Facebook posts provided data for the qualitative study. Castells' 'network society' enabled us to explain how youths formed a 'network of protesters' to resist a repressive police system. The #EndSARS protest was another opportunity for the Niger Delta youths to express their dissonance with an exclusionary political arrangement. [ABSTRACT FROM AUTHOR]

Greater involvement of women is globally believed to enhance environmental management outcomes. Despite being disproportionately affected by environmental degradation primarily caused by oil spills in the Niger Delta region of Nigeria, women in the region are often excluded in environmental decision-making processes. Women involved in farming and fishing face increased vulnerability to contaminated land, food insecurity and conflicts driven by environmental degradation. Using a mixed approach, women, lawmakers, policymakers, regulators, civil society organizations, environmental management practitioners, and government agents responsible for environmental remediation were engaged through interviews, focus group discussions and questionnaires to examine women's inclusion in environmental decision-making and governance in the Ogoni contaminated land remediation project in the Niger Delta region of Nigeria. The results indicate that lack of trust and confidence in drivers of the environmental decision-making process could affect women's participation and involvement in environmental management. Although cultural beliefs and practices impede the participation of women in the region, their actual participation does not independently translate into inclusion in environmental decision-making due to limited capacity, confidence and trust in the process. Creating platforms for capacity building, developing gender policy, adapting appropriate communication strategies, initiating women networks and strengthening social cohesion could enhance women involvement in environmental decision-making in regions with similar cultural context to the Niger Delta region.

The scarcity of pristine, intact ecosystems limits opportunities to learn about succession and ecosystem evolution under conditions of limited human impact. Finima Nature Park (FNP) has been identified as a possible RAMSAR site. Its protected lake—"FNP Lake" (also known locally as "Bonny Lake")—is an unusual habitat that enables monitoring of aquatic ecological succession in the Niger Delta, where pristine and near-pristine ecosystems are becoming scarce. Macrozoobenthos are one of the best-known bio-monitors of ecological health integrity because they are widespread and long-lasting, with moderate mobility and high diversity, among other valuable characteristics. Monthly data of the community structure of macrozoobenthos and some of the FNP Lake's priority abiotic factors were collected in 2018, which provided a baseline for identifying future water quality changes and succession in the lake. Except for temperature and dissolved oxygen (DO), which were spatially uniform, the physico-chemical parameters varied spatio-temporally. The diversity indices values were low. According to the canonical correspondence abundance (CCA) plot, taxa distributions were influenced mainly by pH, DO, and temperature, which explains the prevalence of oxygen-insensitive species.

Deepwater depositional elements are the building blocks of submarine systems and represent the basic mappable elements in seismic volumes. This study utilizes good quality 3-D seismic data of 300 km2 areal coverage in water depth of 500 m to characterise the planform morphology and distribution of channel elements in the upper slope of deepwater western, Niger Delta. The seismic interval of interest (between 500 and 1650 milliseconds two-way time (TWT), informally termed ‘Channel System’, was subdivided into six (6) seismic units - Intra Channels (IC) 1, 2, 3, 4, top channel system (TCS), and undeformed hemipelagites (UH). Seismic interpretation was carried out for each of the seven horizons to derive their respective subsurface TWT maps. The median surface between two successive maps were derived to capture their internal architecture within the seismic units based on reconditioning the seismic volume semblance attribute. The resulting semblance attribute maps, from the Intra Channel 1 (IC1) unit through the overlying units to the Undeformed Hemipelagites (UH) unit presented an enhanced planform morphology of various NE-SW trend channels. The IC1 is imprinted with three channels of varying sinuosity, IC2 is characterised by one non-sinuous channel and one sinuous channel, IC3 indicates three non-sinuous channel, and one sinuous channel, IC4 and the TCS’ are both characterised by several sub-parallel channels and one sinuous channel, while the topmost UH unit displayed several straight slope gullies upslope with imprint of one precursor sinuous channel. The identified channel forms vary in morphology, sinuosity and distribution both spatially and across the stratigraphic succession in the upper slope. The progressive temporal disappearance of the channels is linked to the associated background hemipelagites that acted as blankets over the precursor channels. [ABSTRACT FROM AUTHOR]
