In the literature, there are various accounts of the number of gully sites in Imo State as well as the likely causes of the gullies. The very great depths of some of these gullies and the failure of some control measures strongly suggest that they may actually result from interplay of exogenic (such as weathering) and endogenic (tectonic) forces. The aim of this study therefore was to integrate satellite remote sensing data of the study area with GIS to highlight gully erosion hotspots as well as create a database of erosion sites and attributes. Development of 3D – Digital Terrain Models (DTM) of the area for the purpose of studying topography, characteristics and patterns of gully sites. Integration of the DTMs with processed satellite images to generate data for slope analysis and other spatial attributes of gullying. Study Population: Gully Erosion profiles in Imo State, Nigeria. Duration of Study: 24 months.Methodology: SRTM data and SPOT 5 satellite imageries of Imo State were studied and utilizing the opportunities offered by Remote Sensing and GIS. Google earth images and ground truth were used to confirm gully spots and maps were then generated with vital spatial datasets on the spatial distribution and development of gully erosion in Imo State. Results: The Digital Elevation Model (DEM) data revealed a correlation of low values with areas of high gully erosion susceptibility. There is also a relationship between the drainage, lineament density and gully erosion in the study area. Gullies are concentrated in the northern western section of Imo State and area underlain by the transition zone between Benin Formation and Bende-Ameki Formation while the Northeast flank though on the same relief height is not that affected because of the shale component of the soil, however, this areas is heavily dissected by streams in dendritic pattern. Finally, a correlation was found to exist between the lineament trend and the strike directions of most gully erosions in the area indicating structural control of gully initiation in the area.

This review examines the concept of oil theft and artisanal refining and their environmental implications and concluded that Oil theft and artisanal refining in the Niger Delta are massive and growing problems. It is estimated that between 200,000 and 300,000 barrels of oil is lost daily to theft, known in the country as illegal bunkering. The majority of the stolen crude oil is taken to large ocean-going tankers waiting offshore, which export the oil to refineries outside the country to the rest of the world. Stolen oil is also refined in makeshift individual facilities into low quality petroleum products. The authors conclude that while acknowledging the seeming social and economic advantages that artisanal refining brings to the host communities, and the argument that artisanal refining actuall...

In order to cultivate new ideas and further grow the industry, University of Abuja has gave the opportunity to conduct this research on the university research farm within the permanent site during the 2018 raining season to investigate the performance of ginger and turmeric as influenced by cropping system and NPK fertilizer 15:15;15. The experiment was performed based on split plot system laid in randomized complete block design (RCBD) with 3 replicates used in the study. The treatment with their various level and the intercrop were organized using the various combinations indicated and were filtered into the design used (RCBD). Each replicate contains 12 plots and separated from the plot by one meter pathway. Hence a total of 36 experimental plots were used in the research. The result of the ex...

This paper focuses on the traditional means and or mechanism of resolving violence related conflicts in Nigeria and Africa, with Rivers State as a case study. Rivers State is one of the thirty-six (36) states of Nigeria. It is a heterogeneous society with diverse ethnic nationalities fused together for political and administrative convenience. However, in terms of controlling violence virtually all the ethnic groups in the state share some similarities in resolving violence related cases. To this extent, therefore, the paper seeks to identify the roles of traditional rulers in controlling violence; it examines the effectiveness of the traditional means in the past in relation to the present judicial system. In view of this, the paper highlights the significance of the traditional means of controlling violence in Nigeria. This study examines the extent to which colonial ...

Moreover, two thirds of Bayelsa State and Delta State are inundated by devastating floods for at least a quarter of each year. Communities along the River Niger-Benue system are also under threat of constant flooding. Vulnerability assessment which many regions of the world have commenced becomes the way forward. This paper investigates the vulnerability of communities in three of the Niger Delta States and found out that a total of 1,110 towns are at risk of being inundated and about 7,120,028 people risk displacement. The paper evolves a well thought-out mitigation and adaptation measures which can be adopted by all stake holders including Governments at all tiers, community leaders and the vulnerable population

It has been observed that the severity of weather-related disasters will increase and it appears to have done so in a number of regions of the world in the past and as was experienced in Nigeria in 2012, if the causes of climate change are not urgently mitigated. Flooding is recorded every year in all the states along the River Niger and its tributaries,frequently causing disasters. Moreover, two thirds of Bayelsa State and half of Delta State are inundated by devastating floods for at least a quarter of each year.It is estimated that a metre rise in sea level will displace about 14 million people from the coastal areas of Nigeria. Communities along the River Niger-Benue system are also under threat of constant flooding. Vulnerability assessment which many regions of the world have commenced becomes the way forward. This paper investigates the vulnerability of towns like Bonny, Brass, Nembe, Port Harcourt, and Yenagoa among others to tidal, splash and channel floods. The paper evolves a well thought- out mitigation and adaptation measures which can be adopted by all stake holders, including Governments at all tiers, community leaders and the vulnerable population.
