Sediments are the final sink of heavy metals in the water body. This study examined the concentration of heavy metals in the sediments across the outlet of the Forcados. This was intended to examine the relationship between sediment characteristics and heavy metal concentration across the seasons. Samples were taken across two seasons and tested for heavy metals. Correlation analysis was used to test association between sediment characteristics and heavy metal concentration, while Mann-Whitney U test was adopted to test the difference across seasons. Results show that Total Organic Carbon (TOC) and the particle size distribution have a significant relationship (P<0.05) with correlation coefficient -0.272 and 0.335 for sand and silt respectively. TOC was also found to be positively and significantly correlation with all the heavy metal tested, while V, Ni, Cr, Pb, Cu displayed significant correlation with particle size distribution.

Adegoke Department of Geosciences, University of Missouri-Kansas City Kansas City, MO 64110, USA E-mail: [email protected] Mofoluso Fageja, Godstime James & Ganiyu Agbaje National Space Research and Development Agency, Abuja, Nigeria Temi E. Ologunorisa Centre for Climate Change and Environmental Research Osun State University, Osogbo, Nigeria E-mail: [email protected] Abstract In Nigeria, there is dearth of studies on recent changes on accelerated marine processes along the national coastlines despite their importance as ports for navigation and marine commerce as well as a bridge for aquatic and terrestrial life. This study, which deals with a time series analysis of recent changes in the Niger Delta Coastline using Satellite Imagery is an attempt at filling this gap. Landsat TM images of 1986 and Landsat ETM+ of 2003 both covering the Niger Delta area of Nigeria were used for this study and the images were processed using Erdas Imagine Version 8.7 and Arc Info 9.1 for the GIS operations. The results of the analyses show among other things that coastline erosion was dominant over accretion of sediment deposition. Also that the total area of observed changes along the coastlines was 46.535sq.km. Of this, 27.65sq.km (59.43%) constitutes eroded area, and 40.57% representing 18.88sq.km of the area showed coastal sediment accretion. Keywords: Coastal processes, Marine erosion, Niger Delta, Satellite imagery, Accretion 1.

Within the last fifteen years the Niger delta coastal zone has experienced peak floods between September and October due to intense rains from upstream. Many studies including the United Nations Framework on Convention on Climate Change (UNFCCC) reports, indicate that the Niger delta region could be inundated with water due to the effects of climate change. According to local experts, the Niger delta is subsiding at over 25mm/annum; a situation that can exacerbate the effects of flooding and inundation in the area.

    1 Deltaic Sedimentary Environments in the Niger Delta, Nigeria 2 Chinotu Franklin GEORGE a; David I. M. MACDONALDa and Matteo SPAGNOLOa 3 4 (Corresponding author: Chinotu Franklin GEORGE) 5 a University of Aberdeen, School of Geosciences, King’s College, AB24 3UE, Aberdeen, United Kingdom. 6 Email: [email protected] 7 Phone: +2348035511489, +447978354066 8 9 Abstract 10 This study is focused on the geomorphology of surface sedimentary environments contained in the fluvial, tidal 11 and wave-dominated areas of the Niger Delta. GIS techniques applied to high-quality Landsat and SPOT images 12 were used to identify and map landforms and processes, as well as quantitatively characterise their metrics and 13 spatial distribution. A detailed analysis shows that the extent of the Niger Delta is 70,000 km2, contrary to 14 previous publications that reported 75,000 km2. The delta has also been remapped and classified into mega 15 sedimentary environments: the upper deltaic plain is 69% of the total extent, while the lower deltaic plain and 16 delta front are 25% and 6% respectively. Other subunits were distinguished and mapped within the upper deltaic 17 plain such as fluvial channels, point bars, braid bars, oxbow lakes, and other lakes. Tidal channels, beaches and 18 spits were identified in the lower deltaic plain and delta front. The geometries of these sedimentary bodies 19 (landforms) appear to be relatively scale-invariant, thus meaning that from the measurement of some 20 dimensional parameters (e.g. the length) it is possible to estimate all others (e.g. the width and overall extent).

Ariye is a lecturer in the department of History and International Studies, Isaac Jasper Boro College of Education Sagbama. Presently, he is a Post Graduate Student at the Faculty of Humanities and Social Sciences, SPIRE, Keele University Newcastle, U.K. He is a Social and Political Historian with research interests revolving around, International/Diplomatic History, Intergroup Relations/Niger Delta Studies, Press (Media) and Constitutional History, International Organizations/Law, as well as Peace and Conflict Studies Abstract This paper is a historical exposition of the Ijo people of Delta State in the South-South and Niger-Delta Region of Nigeria. A literature gap exists on these groups compared to their kith and kin in the States of Bayelsa and Rivers, also in the Niger-Delta. Thus, motivated by this, the author employs a descriptive and analytical schema to present the early history of these people with regards to their origins, migrations and settlement patterns. The study also examines aspects of their social and cultural practices. At the end, it is observed that, these groups, like their other Ijo counterparts in the central and eastern delta are equally of considerable antiquity in the Niger- Delta spanning over 7,000 years, blended with a rich heritage that has been developed over time.

  • Modification of Niger Delta Physical Ecology: the Role of Dams and Reservoirs
    il\dro-ecology: Linking Hydrology and Aquatic Ecology (Proceedings of Workshop IIW2 held at lïinuinallam. UK. July 1999). I AI IS Publ'. no. 266.2001. 19 Modification of Niger Delta physical ecology: the role of dams and reservoirs T. K. S. ABAM Institute of Geosciences and Space Technology, Rivers Stale University of Science and Technology, PMB 5080, Port Harcourt, Nigeria e-mail: [email protected] Abstract The Niger Delta is a 40-km2 sedimentary basin with a complex river network and a fragile ecology in which fresh and saline water ecosystems main­ tain a dynamic equilibrium. Large-scale upstream impoundment in dams and reservoirs have over the years drastically reduced flow and sediment delivery to the coast resulting in adjustments to ecological boundaries, coastline geo­ metry, lowered flood water levels and upstream migration of tidal influences. However, as the reservoirs get silted up, they no longer function as effective flow buffers, occasioning increased floods towards the pre-dam levels. Key words Niger delta; ecology; dynamic equilibrium; dams; sediment delivery; coastal erosion; morphology, riverine; river modification; wetlands; saline intrusion INTRODUCTION The River Niger drains a large part of West Africa and discharges its waters and sedi­ ments into the Niger Delta and its extensions into the Atlantic Ocean. Over the years, this process has resulted in the formation of a complex and fragile delta with rich bio­ diversity. The interaction of the drainage processes with the environment has resulted in the evolution of ecological zones as shown in Fig. 1. These are dry flat land, dry land with abundant swamp zones and freshwater swamps.

  • Nigeria's Criminal Crude
    Executive Summary and Recommendations Nigeria’s Criminal Crude: International Options to Combat the Export of Stolen Oil Christina Katsouris and Aaron Sayne September 2013 Read more www.chathamhouse.org/nigeriaoil Executive Summary and Recommendations Nigerian crude oil is being stolen on an industrial scale. Some of what is stolen is exported. Proceeds are laundered through world financial centres and used to buy assets in and outside Nigeria. In Nigeria, politicians, military officers, militants, oil industry personnel, oil traders and communities profit, as do organized criminal groups. The trade also supports other transnational organized crime in the Gulf of Guinea. This report explores the international dimensions of Nigerian crude oil theft. It also tackles the thorny question of what the international community could – and should – do about it. Background Nigeria offers a strong enabling environment for the large-scale theft of crude oil. Corruption and fraud are rampant in the country’s oil sector. A dynamic, overcrowded political economy drives competition for looted resources. Poor governance has encouraged violent opportunism around oil and opened doors for organized crime. Because Nigeria is the world’s 13th largest oil producer – exports often topped two million barrels per day in 2012 – high rents are up for grabs. The basic story of how Nigeria’s crude goes missing has been told for years. To steal oil, thieves tap into pipelines and other infrastructure in the Niger Delta. They then pump the oil onto waiting barges and boats. Some of it is refined locally while larger vessels carry the rest abroad. There are also allegations that oil vanishes from at least some of the country’s roughly two dozen export terminals.

The choice of anchored steel – sheet pile is incompatible with shore bathymetry resulting to insufficient embedment depth and eventual collapse. Only Sagbama and Otuokpoti schemes performed adequately for 30 and 25years respectively, thus attesting the suitability of Pilarczyk equation for revetment design. The assessment on impact of design on successful project implementation revealed that the non-engagement of design consultants with core competence in hydraulic/river engineering underpins the prevalence of faulty designs and widespread revetment failures being experienced in the region.
