The Impact

This writing will focus on the impact on the impact of oil and gas development on the landscape, surface water and groundwater of the Niger Delta – while also assessing the various means of remediation in use. Geologically, the Niger Delta petroleum systems consist of Lower Cretaceous , Upper Cretaceous–lower Paleocene and Tertiary. When Nigeria became an independent nation on 1 October 1960, Shell–BP began to relinquish its acreage and its exploration licenses were converted into prospecting licenses that allowed development and production. The Federal Government of Nigeria started its Department of Petroleum Resources Inspectorate in 1970 and Nigeria joined the Organization of the Petroleum Exporting Countries in 1971. – and in order to take control of the country’s petroleum industry, Nigeria nationalized BP’s holding completely in 1979, and Shell–BP became Shell Petroleum Development Company of Nigeria. Oil spillages routinely occur in the Niger Delta. The official figures of SPDC show that between 1976 and 2001, 6,187 incidents in which 3 million barrels were spilled. The Niger Delta Environmental Survey An impact assessment of the 1983 Oshika oil spill. Spills of crude oil in Niger Delta farmlands have been reported since 1971. In general, toxicity depends on nature and type of crude oil , level of oil contamination, type of environment and degree of selective of individual organisms. Controlled burning effectively reduce the amount of oil in water, if done properly but it must be done in low wind and can cause air pollution. A principal target for emissions reduction is flaring and venting which causes most of the air pollution. Saltwater tanks can be often susceptible to lightning strikes due to build up in static electricity, with the spilled oil spreading to surrounding lands, waterways. This requires a secondary containment of the tanks that makes it easier to clean up the inevitable spill. In cases of expected major storms or flooding events, crude oil can be removed from tank batteries while refilling the tanks with saltwater to prevent them tipping over during the flooding event.

The Impact

ABSTRACT Studies were carried out to detect and quantitate 12 microbial processes occurring in sediments in the north central Gulf of Mexico, and to determine the impact of low-level concentrations of oil on these processes. Under the simulated in situ conditions employed, photosynthesis, nitrification, dentrification, nitrogen fixation, sulfate reduction, and phosphate uptake were minimal, while sulfur oxidation and catabolic carbonaceous processes (heterotrophic activity, lipolysis, proteolysis cellulolysis, and chitinolysis) were present with varying degrees of activity. Little difference in metabolic activity was detected between oil-production platform sites and corresponding control sites, among different sediment types, or among three sampling seasons, and the presence of oil at up to 200 microliter per milliliter sediment had no significant impact on reaction rates. Pure culture studies confirmed that low-level concentrations of crude oil had essentially no effect on these processes.

Fault Lines

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 Impact

This paper aims to examine the main determinants of inflation in Vietnam during the period from 2002Q1 to 2013Q2. The cointegration theory and the Vector Error Correction Model (VECM) approach are used to examine the impact of domestic credit, interest rate, budget deficit, and crude oil prices on inflation in both long and short terms. The results show that while there are long-term relations among inflation and the others, such factors as oil prices, domestic credit, and interest rate, in the short run, have no impact on fluctuations of inflation. Particularly, the budget deficit itself actually has a short-run impact, but its level is fundamentally weak. The cause of the current inflation is mainly due to public's expectations of the inflation in the last period. Although the error correction, from the long-run relationship, has affected inflation in the short run, the coefficient is small and insignificant. In other words, it means that the speed of the adjustment is very low or near zero. This also implies that once the relationship among inflation, domestic credit, interest rate, budget deficit, and crude oil prices deviate from the long-term trend, it will take the economy a lot of time to return to the equilibrium state.
