Abstract Background: This research looks at the assessment and mapping of coastal flooding in Niger-Delta region of Nigeria, staring at the three local governments (Bonny, Okrika, and Ogu/Bolo) in Rivers State that lies at intervals the shores of Atlantic Ocean. Result: At the analysis it was found that most of the study areas lies at the creek and with the steady rise of the sea level, as a result of increase in temperature, most of the study area will have steady occurrence of flooding. Conclusion: Adaptation measures like dike construction, maintenance of natural dune systems, protection of coastal ecosystems, planting of vegetation around the coastal areas and different flood proofing and accommodation activities should be put in place to checkmate flooding in those areas.

Exploration Activity

The discovery of crude oil in Oloibiri-a town in the present Bayelsa state, Niger-Delta region of Nigeria) in 1956 and the subsequent exploration activities have over the years impacted tremendously not only on the ecosystem and livelihood pattern of the Niger Delta but on the pattern of conflicts that has trended.. While resources accruable to Nigeria from sale of crude oil are shared by all, the impacts of oil spill an offshoot of crude oil exploration activities are borne solely by the Niger Delta region. Oil spill appears to have found a permanent abode in Bayelsa state; from Southern Ijaw to Sagbama local governments, Olodiama to Azuzuama communities. Local communities are faced with the problem of continuous oil spill. This in turn has brought about conflicts between oil bearing communities and oil companies. These conflicts in some instances led to shut down of operations of oil companies, vandalism, and reduction of Nigeria’s crude export. In view of the illustrated background, this study examined the strategies for management of oil spill related conflicts in Bayelsa state regarding that oil spill is a key impact of crude oil exploration activity. Findings revealed that the strategies deployed in the management of oil spill in the state can be categorised into three: community strategies, regulators and non-governmental organisations strategies.

Adaptation Measures

Based on the Japanese governmental adaptation plan against the influence of climate change, the local governments promptly have to design such measures. We focused on the vulnerability of storm surge disasters along the innermost coast, Saga Plain, of the Ariake Sea (Fig.1a) since most of the area is below sea level. We present our experiences of the attempts to design adaptation measures from various approaches as collaborative research with members of Saga Prefecture. Figure 1b shows a meeting with members of the prefecture.

Abstract. In the Lesser Antilles, coastal inundations from hurricane-induced storm surges pose a great threat to lives, properties and ecosystems. Assessing current and future storm surge hazards with sufficient spatial resolution is of primary interest to help coastal planners and decision makers develop mitigation and adaptation measures. Here, we use wave–current numerical models and statistical methods to investigate worst case scenarios and 100-year surge levels for the case study of Martinique under present climate or considering a potential sea level rise. Results confirm that the wave setup plays a major role in the Lesser Antilles, where the narrow island shelf impedes the piling-up of large amounts of wind-driven water on the shoreline during extreme events. The radiation stress gradients thus contribute significantly to the total surge – up to 100 % in some cases. The nonlinear interactions of sea level rise (SLR) with bathymetry and topography are generally found to be relatively small in Martinique but can reach several tens of centimeters in low-lying areas where the inundation extent is strongly enhanced compared to present conditions. These findings further emphasize the importance of waves for developing operational storm surge warning systems in the Lesser Antilles and encourage caution when using static methods to assess the impact of sea level rise on storm surge hazard.

Aims: To make comparative analysis of the indications and outcome of paediatric echocardiography in tertiary centers in Rivers State, Nigeria using the Appropriate Use Criteria (AUC) guidelines [11].    Methodology: A retrospective analysis of 645 echocardiography requests done between July 2019 to June 2020. Patients’ biodata and indications for echocardiography and echocardiography diagnosis were retrieved. Using the AUC guidelines, each indication was scored from 1 to 9, after which they were categorized into Appropriate, May be appropriate and Rarely appropriate to determine the respective percentages accordingly. Cochran-Armitage test for trend was done to assess degree of yield of cardiac anomaly for each level of AUC classification while bivariate associations were assessed using persons chi squared tests. Results: There were 645 echocardiography requests within the study period. The median age was 5months, with interquartile range of 2months to 24months. There were 355(55%) males and 290(45%) females. The clinical indication for echocardiography was appropriate in 490(76.0%), May be appropriate in 32(5.0%) and Rarely appropriate in 104(16.1%). Nineteen (2.9%) clinical indications were “Unclassified” under the AUC. Echocardiography showed abnormality in 544(84.3%) reports, among which children with “Appropriate indications” had the highest yield 457(93.3%), while “unclassified indications” had the lowest yield 8(42.1%). The yield for cardiac anomalies significantly decreased with decreasing appropriateness (p=0.00001). Conclusion: Most indications for paediatric echocardiography in our centers were appropriate according to the AUC guidelines. The AUC guidelines are applicable in resource poor settings.

Health insecurity is a major problem affecting the well-being of internally displaced persons in Nigeria. In the Niger Delta region, the situation remains virulent with attendant consequences on the displaced population. This study investigated health insecurity among the internally displaced persons. Data were sourced across three States of the Niger Delta Region, identified among areas with a high rate of internal displacement. Human Security Approach was employed as a theoretical framework. A total of 582 respondents (Bayelsa = 206, Delta = 211, and Rivers = 165) who had been displaced between the year 2012 to 2018 were randomly selected, and a questionnaire was administered. Findings indicated that 51.9% of respondents in Delta state, 50.0% in Rivers state, and 35.7% in Bayelsa state were diagnosed with diseases resulting from flood displacement. The diseases diagnosed were high blood pressure, cholera, hernia, malaria, measles, tuberculosis, and typhoid. While the diagnosis of blood pressure was high in Bayelsa (3.9%) and Delta (3.5%), the diagnosis of cholera was not recorded in Bayelsa and Delta States but Rivers state (3.4%). Those displaced by flood were 0.4 times less likely to experience abnormal health status than those displaced by other causes. The study concluded that displacement has serious implications on the health of internally displaced persons. It, therefore, recommended that medical centres should be cited in displaced camps to cater for the medical needs of the displaced population.
