Abstract:

The forest zone of West and Central Africa comprises the coastal and adjacent inland regions bounded the semi-deciduous forests in the west and the equatorial forests in central Africa and the Congo basin. Sedimentary plains, developed mostly on weathered sandy materials, lie along the coastal stretches and cover vast areas of the Congo basin. Behind the coast the plain rises gradually to hills and plateaus of much lower elevation than those of the highlands of East Africa. Two great rivers, the Niger and the Congo, which discharge huge volumes of fresh water to the Atlantic Ocean, are major contributors to the hydrological cycles of the rain forests ecosystems of the Guinea–Congo Region. The Niger originates from the forested highlands of Guinea and discharges its waters into the Bight of Benin by way of a large delta in southern Nigeria. The Congo basin occupies an immense area of 750 000 km2, surrounded by Pre-Cambrian uplands. The alluvial floor of the saucer-shaped basin is flat, and marshes and swamps comprise a large proportion of the total area. The highlands and plateaus along the rim are low to the west and north and higher to the south. To the east, they merge with the mountains of the Great Rift Valley of East Africa (Gann & Duignan 1972; Hance 1975; Grove 1978; Hamilton 1989).

Abstract:

Flooding is recurrent in Nigeria, occurring yearly at different scales. This geared the need for a study to reveal local government areas (LGAs) that are at risk and vulnerable to flooding. The multi-criteria approach was adopted, using geospatial techniques and data. Factors considered were elevation, slope, rainfall intensity, and distance to river. The factors were classified, reclassified, rated, and weighed in a systematic process. Nineteen states and 114 LGAs face high risks, especially communities in the Niger Delta, around the lagoons of Lagos, along River Niger, Benue, and the Cross-River. Also, 125 LGAs in 18 states face medium flood-risk vulnerability. Consideration the population density of communities, Lagos State is the most vulnerable because of LGAs with high population densities within high flood-risk zones. Other states with communities exposed to high flood-risk vulnerability include Rivers, Kogi, Cross River, Akwa Ibom, Anambra, and Delta. The study provides information key to proactive policy formulation, mitigation, and adaptation to flood risk in Nigeria.

Abstract:

Abstract The concentrations of polychlorinated biphenyls (PCBs) in sediment samples from the New Calabar River in the Niger Delta Region of Nigeria were determined. Grab sediment samples were collected from five stations in the river and analyzed for individual PCB congeners using gas chromatography - mass spectrometer. The Σ8PCB (sum of eight congeners) identified in the samples ranged from 0.21 to 2.16 mg/kg. Congener 105 and 194 were the most and least abundant with 34.65 % and 2.46 % respectively. The lower chlorinated congeners (below PCB 101) were prominent with 54.68 % of the total PCBs concentration in the sediments. The results of this study should make PCBs contaminants of grave concern in the Niger Delta Region.

Abstract:

ABSTRACT Using the basis that communities having high biodiversity are inherently more valuable as an ecological resource, the authors have derived a preliminary system of classifying the tropical environments of the oil-producing delta regions of Nigeria based on a number of field-collected parameters that measure the degree of biodiversity as well as potential spill persistence and difficulty of cleanup. Physical parameters to be measured include type of substrate, presence of near-surface groundwater and inhibiting layer, and extent of surface debris. Biological parameters include tree density (stocking), coverage by grasses and shrubs in the under-story, plant condition, species richness and diversity (mammals, reptiles, amphibians, birds), important medicinal or endangered species, and special or unique biological features. Each factor is given assigned weighting values based on over 20 years of oil spill experience. The weighting given to spill persistence factors is 25%, while 75% is given to biological parameters. The sum of species richness and diversity is one-third of the entire valuation. Once all parameters are measured and tallied, sensitivity classification will be divided into five to ten categories. Initial data collection was undertaken during 1999. Additional fieldwork to collect and test each factor is planned for the year 2000. Sensitivity maps, including the classification of both coastal and inland habitats, will then be prepared in a GIS (Geographic Information System) format.

Abstract:

Distribution of Lindane in Water, Sediment, and Fish from the Warri River of the Niger Delta, NigeriaThis paper is the first attempt to quantify the levels and the distribution pattern of lindane in the surface water, sediment and fish (Chrysichthys furcatus and Tilapia zilli). The samples were collected from three stations (Ovwian, Ekakpamre, and Ovu) of the Warri River in the western Niger Delta of Nigeria in 2006: during the dry (January-April) and wet seasons (May-August). The analysis included a total of 96 samples made up of 24 samples each for water, sediment, and fish. The pesticide levels were analysed using high performance liquid chromatography to elucidate its distribution in various environmental compartments. Residue levels in the matrices ranged from below the detection limit (BDL) to 1.37μg L-1 in water, BDL to 12.66 μg g-1 dry weight (dw) in sediment, BDL to 16.67 μg g-1dw in Chrysichthys furcatus, and BDL to 0.15 μg g-1dw in Tilapia zilli. The observed values were above the ecological benchmarks (0.01 μg L-1) recommended by the Nigerian Environmental Protection Agency and European Union. They were also relatively higher than in previous studies on the Nigerian environment, which calls for regular monitoring of the Niger Delta water bodies.

Abstract:

In this study, the concentrations of inducers of environmental toxicity such as heavy metals and polycyclic aromatic hydrocarbon and biomarkers of environmental toxicants such as oxidative stress enzymes/compounds and liver function enzymes were determined. These parameters were used to assess the pollution status of some Niger-Delta areas; Ebocha/Omoku, Abacheke/Egbema, and Okwuzi/Ohaji, with the aid of two indicator species: cat fish (Ictalurus punctatus) and snakehead fish (Channa argus) from three different water sources; Ebocha/Omoku river, Abacheke river and Okwuzi creek all of which are within the area of oil exploration and production activities in Nigeria. The control fish and water samples were collected from Otamiri River within the Federal University of Technology, Owerri, Nigeria, with no known oil exploration and production activity. The results obtained indicated significant (p < 0.05) differences between the exploited and the unexploited environment and the need to incorporate biochemical markers in environmental impact assessment of aquatic environments to complements the classical chemical monitoring.

Abstract:

A study on the catch composition and diversity of cast net fisheries was conducted between May and August, 2017 in the New Calabar River, Rivers state, using cast net of varying mesh sizes (1.5mm and 2.5mm). Fish samples were collected from three sampling stations, viz. Station1- Aluu, Station 2- Choba and Station 3- Iwofe. The fish species recorded comprised of 26 species under 11 families, and one decapod crustacean. The three most abundant species were; Coptodon guineensis (25.11%), Coptodon zilli (18.56%) both from the Cichlidae family, and Penaeus nitialis (10.90%) from the Penaeidae family, while the least abundant species was Liza grandisquamis (0.13%) from the Mugilidae family. The diversity indices showed that station 2 recorded the highest number of species (21) while station 1 recorded the lowest with (12) species. Simpson’s indexes of diversity, Simpson’s reciprocal index, Shannon- weiner index, and Pielou’s evenness index, were estimated. This study serves as a base line data which will assist relevant bodies in the management and conservation of fisheries resources in the New Calabar River. It is therefore recommended that for an improved and sustainable exploitation and management of fisheries resources of the New Calabar River, proper monitoring and management for fish stock must be done.J.

Abstract:

The history of history-writing in the Niger Delta was first developed by E.J. Alagoa. However, his work, which covers the periods from 1508 to 1988, does not go into the twenty-first century. This is the case as well for N.C. Ejituwu, who extended the Delta historiography to 1999 but without including his own innovations. For this reason, this paper discusses the innovations brought by Ejituwu's role in the development of Niger Delta historiography. These are his contributions to the training of historians, the introduction of feminist history, biographical writing, and history concourse. Others include his reconstruction of the settlement histories of many Eastern and Central Niger Delta groups. Its impact on the development of the Delta historiography, analyzed here, furthered historical research in the region. Although largely a study of the work of N.C.Ejituwu, this paper is also intended as an overview of Niger Delta regional history of history writing.According to Ake, development concerns human creativity, socially or economically. N.C. Ejituwu has demonstrated his creativity in historical writing on aspects of the Niger Delta, a region of some 75,000 square kilometers stretching from the Mahin estuary in the west to the Cross River estuary in the east. This most southerly region of Nigeria has about fifty linguistic groups located on its islands and peninsulas. Historical writing in the Delta concerns these fifty clans of the Ijo ethnic nationality. Their settlement histories have been documented by Alagoa, Cookey, and Ejituwu.

Full text

Abstract:

Investigation of the levels of organochlorine pesticides (OCPs) in fish samples was carried out to assess the contamination status of Niger River. Ten different brackish water species of fish (6 samples for each, making a total of 60) were purchased from landing sites at the Delta area of Niger River. These were Drapane africana, Mochokus niloticus, Chrysichthys nigrodigitatus, Pristipoma jubelini, Vomer septapinis, Pseudotolithus senegalensis, Mugil cephalus, Pseudotolithus elongatus, Sphyraena piscatorum, and Lutjanus goreensis. OCPs were determined using standard methods. Certified reference standards from Accustandard USA were used for the instrument calibration and quantification of OCPs. Twenty OCPs, namely, α-HCH, β-HCH, γ-HCH, δ-HCH, endrin, endrin aldehyde, endrin ketone, heptachlor, heptachlor epoxide, aldrin, dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, methoxychlor, α-chlordane, γ-chlordane, DDE, DDT, and DDT, were identified/quantified using Gas Chromatography (GC) (Hewlett Packard GC 5890 series 11 with electron capture detector). Confirmation was done using Shimadzu GCMS QP2010. The highest concentration of ∑OCPs in the brackish fish samples of the Niger River, 4302±2066 µg/kg fresh weight, with a range of 2237-6368 µg/kg, was detected in Drapane africana, while the lowest concentration, 2320±876.4, with a range of 1006-3288 µg/kg, was found in Mochokus niloticus. The concentration of total OCP compounds varied markedly amongst the different fish species. The guideline value of 2000 µg/kg fresh weight by WHO/FAO was exceeded and therefore implied potential harmful effects on humans. Since contamination of the fish samples was an indication of contamination of the river, the quality of the water for public water supply should be of concern; and therefore further monitoring is suggested.

Abstract:

Variations in the water quality of the Imo River estuary was investigated by measuring values of selected physico-chemical parameters. Samples were collected bi-monthly between April 2015 and March 2016, covering the dry and wet seasons of the year. Three stations were selected: upstream (Kalibiama), midstream (Opobo) and downstream (Queenstown). Analysis of results showed that physico-chemical parameters were affected more on seasonal than spatial scale. Principal component analysis carried out indicated that values of most of the parameters recorded within the stations clustered together. On the other hand, dispersed values were recorded in months and seasons with significant variations at (p≤0.05) among most parameters. The high spatial variations in phosphates, suspended solids and lead could be associated to human activities like laundry and waste disposal within Opobo and Kalibiama stations. While, high seasonal variability in most parameters could be associated with intense sunshine, cloud cover and tidal intrusion/dilution due to runoff. It can be concluded that nutrient fluxes due to nitrogenous fertilizers are not a problem within the estuary. However, chemical factors and biodegradable components which cause fluctuations in biological oxygen demand are more of the challenge. Keywords: Land-use, nutrient flux, water-quality, pollution, coastal wetlands.

Abstract:

Niger Delta region is very rich in oil and gas deposits, clay, agricultural land, fisheries, extensive forest and other resources. They are nine states which make the region namely, Abia, Akwa Ibom, Bayelsa, Cross River, Delta, Edo, Imo, Ondo and Rivers. The most oil producing communities among them are Akwa Ibom, Bayelsa, Edo, Delta and Rivers State. Clay is equally found in abundance in all the states like crude oil is found in Niger Delta communities. The available clay mineral in the region has the capacity to transform the nation’s economy if properly utilized. Clay is the basic material for pottery or ceramics production. It is also used to ease the penetration of pipes in drilling of crude oil. This paper looks at the practice of pottery in Niger Delta Area with a focus on pottery practice in both Akwa Ibom and Rivers States. Indigenous and contemporary pottery or ceramics practices in these communities indeed have played vital role in the economic, social religious and cultural ways of life of the people. Clay products such as dinnerware and sanitary wares and others are highly sought for and they have the capacity to boast the national economy as experienced in other nations such as Japan, Italy, Britain, United States of America, India and China among others. Data were collected from both primary and secondary sources and were subsequently assessed. The result shows that proper utilization of clay found in Niger Delta has the potential to create numerous job opportunities for the teaming population of youths in the region. The availability of abundant clay in the region, if well harnessed could adequately compete with crude oil exploitation for economic purposes in the region.

Abstract:

Length-weight relationships (LWRs) and condition factor are important biological information to assess the growth pattern and wellbeing of fish species influenced by numerous abiotic and biotic factors. To date, no data on the LWRs and condition of mullets in Sombreior River, Niger Delta. Hence, this research was conducted to determine abundance, length–weight relationship and Fulton’s condition factor (K) of three species of fish belonging to family Mugilidae in Sombreior River, Nigeria. There were a total of 248 samples from five sampling stations for a period of months. Fish species were of various sizes ranging from 24.66±0.40 to 26.35±0.26cm in length and 141.41±6.30 to 161.56±5.87g in weight. For the three species, slope (b) values ranged from 2.18 to 2.68 indicating a negative allometric growth of all fish species. The mean condition factor ranged from 0.89±0.03 forsix Mugil cephalus to 0.93±0.03 for Parachelon grandisquamis while the coefficients of determination (R2) of the LWR regressions ranged between 0.64 (Neochelon falcipinnis) and 0.79 (Parachelon grandisquamis). It was concluded that the mullets in the Sombreior River had a negative allometric growth pattern and the condition is showing the species were in good state of well-being since mean K values are greater than 1.
