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.

The exploration, production and refining of crude oil has led to severe environmental degradation in the oil producing communities of the Niger Delta region of Nigeria. Enhanced bioremediation of tropical rainforest soil artificially polluted with crude oil, bioaugmented with nitrogen fixing bacteria (NFB) and biostimulated with poultry droppings was carried out ex situ. Soil sample was collected at 15cm depth from tropical rainforest soil of the University of Port Harcourt, Nigeria. The NFB was isolated from roots of leguminous plant Arachis hypogea, identified as Nitrobacter species. Bioaugmentation by application of NFB served as option A, option B (biostimulation by application of poultry droppings), option C (No amendment) served as the control. Bioremediation was monitored for 28 days for interval of 14 days, and determined using the percentage ratio of total petroleum hydrocarbon (TPH) losses for each period to TPH at initial day (day zero). Results of total culturable heterotrophic bacterial (TCHB) counts showed that highest range in option B (1.9×104- 2.4×109Cfu/g) than in option A (7.8×106 -2.29×107Cfu/g) and C (6.75×106 -2.6×107Cfu/g) respectively. Similarly, hydrocarbon utilizing bacterial (HUB) counts had higher range in option B (1.20×105 - 1.9×107Cfu/g) than in option A (8.30×104 - 2.30×105Cfu/g) and option C control (4.3×104 −1.69×105 Cfu/g) respectively. Changes in physicochemical parameters during the study showed reductions in nitrate, phosphate and TPH in all the options expect pH which showed slight increase in option C (6.20-6.24). Characterization and identification for bacteria revealed the following HUB genera Pseudomonas, Citrobacter, Bacillus, Corynebacterium, Micrococcus, Klebsiella, Staphylocuccus and Nitrobacter). The percentage losses in TPH from gas chromatography (GC) results showed the following; option A (44.24%) option B (61.08%) and option C - control (27.28%) respectively. The results from this study showed that option B, the application of poultry droppings as biostimulant was more efficient than the application of NFB in enhanced bioremediation of crude oil polluted soil, hence the use of poultry droppings which is available as organic waste, eco-friendly and cost-effective is recommended asbiostimulant for enhanced bioremediation in environmental cleanup of crude oil impacted-sites of the Niger Delta region of Nigeria. Key Words: Bioremediation, Crude oil polluted-soil, Biostimulation, Bioaugumentation, Poultry droppings, Nitrogen fixing bacteria.
