Linguistic Framework

The constant exploration and exploitation of crude oil in the Niger Delta area of Nigeria had had a negative consequential effect on the entire ecosystem of the region. This has been a source of national and international concern and has attracted the attention of scholars from several disciplines, within and outside the region. Creative writers were not left out and this had given birth to which poetry was one of its most prolific genres. Though regional, the literature in general and poetry, in particular, had attracted myriads of attention from eco-literary criticism while the language of the poems had been understudied. Therefore, this study is a linguistic analysis of Niger Delta environmental poetry. Seven poems were purposefully selected from Tanure Ojaide’s Songs of Myself: Quartet (2015) and Nnimo Bassey’s We Thought It Was Oil but It Was Blood (2002).  The Hallidayan Transitivity system of the Experiential meaning of the clause was adopted as a linguistic framework to show how the ecological realities of the region were encoded in the structure of the clause. The study revealed that the nature of the processes and the participants’ roles aptly encoded ecological degradation in the structure of the clause.

The People

Gas flaring, which has assumed a worrisome dimension globally, is one of the environmental problems affecting the NigerDelta region of Nigeria. It has caused untold socio-economic, environmental and psychological effects on the people andtheir communities. Combating the problem has proved Herculean, especially owing to the lackadaisical attitudes of both thefederal government of Nigeria and the various oil companies whose activities have constituted the menace of oil flaring. Thiswork, therefore, assesses the origin, impact and various responses to the problem of gas flaring in the Niger Delta regionfrom historical and chronological perspectives. The work also examines how gas flaring has contributed to the depletion ofthe Ozone layer as well as its greenhouse effect and maintains that adequate measures must be put in place to addressthe problem vis- ` a-vis other crude oil-related environmental degradation in the region. It suggests possible remedies to theproblem placing emphasis on multifaceted approaches.

Cost Effective Method

Bioremediation technologies are an environmentally friendly approach for the treatment of polluted soils. This review take a look at the various remediation efforts by various scientist to ameliorate the effect of crude oil contamination on the environment. Contamination of the total environment (air, soil, water and biota) by crude oil has become a paramount interest in the Niger Delta region of Nigeria. With the frequent reports of oil spillages in the Niger Delta area, there is need to seek for a cost effective method for remediation of crude oil impacted soils. Studies have revealed variable impacts of oil toxicity on the environment and exposed populations. Soil contamination is caused mainly by the leakage of underground storage tanks and pipes. The most common conventional method for the remediation of contaminated soils is excavation followed by landfilling or incineration and other technologies that have been widely practiced. Contaminated sites pose a threat to human life due to severe health problems caused by adverse health effects from exposure to soil contamination. Once it is being detected, assessment strategies, type of sampling, chemical analyses, evaluation of parameters and its effect must be done. Several technologies and parameters have been developed to treat petroleum hydrocarbon contaminated soil but the problem still exists.

Oil spillage is a major environmental threat in south south of Nigeria where most of oil exploration and exploitation activities takes place. If this goes on unchecked or poorly managed, it would lead to total annihilation of the ecosystem. The objective of this study is to develop a model for the prediction of potassium depletion in the crude oil contaminated soil with time using regression analysis. Each sample containing 10kg of soil was artificially polluted with 0.5, 1.0, 1.5, 2.0, and 2.5 liters of crude oil (Bonny Light).  The potassium concentrations were determined using standard methods. Results shows that the concentration of residual potassium in the soil for all the volumes of crude oil introduced into the soil decrees significantly with time when compared to values obtained for the control samples. The concentration of residual concentration in the control soil sample was about three times higher than the concentration obtained for other samples. The results obtained from the derived model were very close to the experimental value. The model is suitable for determining potassium content in crude oil polluted site.

Surface Active

Crude oil obtained from different locations in the Niger Delta area of Nigeria was analyzed by Infrared Absorption Spectrometric technique using Nicolet IS5 Fourier Transform spectrometer to identify the functional groups and compounds in the samples. Results obtained revealed that the amount of surface active components in the crude was in following trend, sample E > sample A > sample C > sample D > sample B, while the level of biodegradability follows the trend; sample E > sample B > sample A > sample C > sample D. Results show that Sample E has the highest amount of surface active components as well as the highest level of biodegradability. Sample B has the least amount of surface active components, while sample D has the least level of biodegradability. The presence of functional groups such as amines, sulfates, isocyanates, hydroxyl, halo compounds, thiols and nitro compounds in the crude increases the surface active properties of the crude due to their polarity and hydrophilicity, which influences the interfacial tension of the crude and the oil recovery efficiency. The level of crude biodegradability is dependent on the amount of aliphatic saturates in the crude, the concentration of acidic components as well as sulphur and nitrogen compounds in the crude. Infrared spectroscopy identifies the functional group in crude samples, this is necessary in knowing the amount of the surface active components and the level of biodegradability of crude oil.

This study presents an interdisciplinary approach towards a critical analysis of some impacts of crude-oil exploration in Niger Delta and polemics of viable conϐlict resolution framework. This approach involves analysis of Ahmed Yerima’s creative portrayal in Hard Ground which revolves around the variables activating conϐlicting emotional interests in matters concerning ‘black gold’ in Nigeria, and how these variables resonant in debates and demands for Nigeria’s polity restructuring because of perceived resource mismanagement. More so, our scope includes an analytical attempt at illuminating elaborately our interpretation of the dimensions to the loud and shrewd inclinations subsuming what some see as solution to the lingering conϐlict, and the suppositions explaining why others see the debates and demands on polity restructuring as dark convoluted ploys aimed at hidden agenda. Hence, through select theories of victimhood, this study attempts to elucidate on the variables propelling conϐlicting emotional interestsabout oil exploration in Niger Delta, by looking interpretively hard and deep on the perspectives, views and suppositions deϐining the ideologies and inclinations propelling them. In the end, this study notes that the disenchantments and troubles with Nigeria’s polity framework and structure as it relates to oil exploration in Niger Delta are subsumed in Hard Ground’s creativecontribution as a means of assessing the points to the fault-lines that characterize the subsisting socio-political structure upon which Nigeria stands and wobbles.
