Adoption of Rice Technologies Introduced by the United States Agency for International Development in Anambra and Ebonyi States, Nigeria

The study determined the levels of adoption of improved rice technologies introduced by USAID MARKETS project phase one in Anambra and Ebonyi States, Nigeria. The population of the study included all project participant rice farmers of USAID MARKETS project in both Anambra and Ebonyi States. A total sample of 80 respondents (40 project farmers from each state) were selected using purposive and simple random sampling techniques. An interview schedule was used for data collection, while percentage and mean statistics were used to analyze data. The results of the study revealed that mean ages of the project farmers (PFs) was 46.56years while 86% of the PFs were literate and the mean rice farming experience was 22 years. The mean total rice farm land owned by PFs was 2.99 hectares mainly on rented basis, while majority got information on rice production and processing from the project. The project farmers highly adopted the following innovations; use of FARO 44 seed variety, carrying out a seed germination test before planting, carrying out appropriate land preparation using either manual or machinery (tractor), seed broadcasting on wet field and upland rice, use of herbicide and storage of paddy produce (packing bagged rice grains in cool dry, fumigated and aerated conditions)

Stroke prevalence amongst sickle cell disease patients in Nigeria: a multi-centre study

Background: Stroke is a life-changing, debilitating complication of sickle cell disease (SCD). Previous studies had recorded high stroke prevalence amongst this group of patients. Nigeria has a large population of people affected by this condition and this study aims to assess the stroke prevalence in this large population.Methodology: Stroke prevalence data from 14 physicians working in 11 tertiary health centres across the country was collated by doctors using the sickle cell registers and patient case notes. This data was then collated and used to obtain the overall stroke prevalence in adult and children.Results: The stroke prevalence in sickle cell disease patients in Nigeria was observed to be 12.4 per 1000 patients. Prevalence in the adult patients was 17.7 per 1000 patients and 7.4 per 1000 patients in children. Twenty three percent of the affected patients had more than stroke episode.Conclusion: The stroke prevalence in Nigeria is lower than previously recorded rates and further studies will be required to investigate other factors which may play a role.Keywords: sickle cell, stroke, Nigeria, prevalenc

Asymmetric response of forest and grassy biomes to climate variability across the African Humid Period : influenced by anthropogenic disturbance?

A comprehensive understanding of the relationship between land cover, climate change and disturbance dynamics is needed to inform scenarios of vegetation change on the African continent. Although significant advances have been made, large uncertainties exist in projections of future biodiversity and ecosystem change for the world's largest tropical landmass. To better illustrate the effects of climate–disturbance–ecosystem interactions on continental‐scale vegetation change, we apply a novel statistical multivariate envelope approach to subfossil pollen data and climate model outputs (TraCE‐21ka). We target paleoenvironmental records across continental Africa, from the African Humid Period (AHP: ca 14 700–5500 yr BP) – an interval of spatially and temporally variable hydroclimatic conditions – until recent times, to improve our understanding of overarching vegetation trends and to compare changes between forest and grassy biomes (savanna and grassland). Our results suggest that although climate variability was the dominant driver of change, forest and grassy biomes responded asymmetrically: 1) the climatic envelope of grassy biomes expanded, or persisted in increasingly diverse climatic conditions, during the second half of the AHP whilst that of forest did not; 2) forest retreat occurred much more slowly during the mid to late Holocene compared to the early AHP forest expansion; and 3) as forest and grassy biomes diverged during the second half of the AHP, their ecological relationship (envelope overlap) fundamentally changed. Based on these asymmetries and associated changes in human land use, we propose and discuss three hypotheses about the influence of anthropogenic disturbance on continental‐scale vegetation change

Decoupling of economic activity and freight transport volume: An evidence for short sea shipping future in the ECOWAS sub-region

This paper explores the decoupling trend between GDP and freight volumes in the ECOWAS states to develop short sea shipping model for the ECOWAS sub-region aimed at reducing the cost per transported unit within the sub-region. The research is based on cross-sectional data from ECOWAS countries spanning from 2000 to 2013 and sourced from the ECOWAS Commission and National Bureaus of Statistics of some member countries. The data were analysed using arc elasticity which is a transport demand modelling tool, to determine the level of variations among trade volumes in the ECOWAS sub-region. It was discovered that total freight volume improved proportionally with growth in GDP for most of the periods in the ECOWAS member countries. This is confirmed by the coefficients of elasticity close 1 or higher than 1. In certain periods, however, the coefficient of elasticity of total freight volumes was found to be approximately zero, thus, indicating that considerable potential freights were lost. More stable values have the coefficients of general elasticity below 1. In most of the ECOWAS countries, the coefficients of general elasticity are unstable, both negative and positive values have a range of values (from -43.709 to 52.364). Hence, freight traffic volume and GDP in the ECOWAS region is highly decoupled. This has raised a serious question as to the prudence of continued dominance of road transport mode for intra-regional freight movement in the ECOWAS sub-region. The result of the study revealed a strong correlation between GDP, the population of member states and the volume of freight in the ECOWAS member countries. The research also showed that the development of short sea shipping model in the sub-region would depend considerably on growth in GDP, improvement in the productivity of the population and increase in seaport corridors of the ECOWAS sub-region

Sonographic biometry of spleen among school age children in Nsukka, Southeast, Nigeria

Background: Normative value of spleen size among school age children is important for objective assessment of the spleen. Objective: This study was aimed at determining sonographically the normal limits of the spleen size according to age, sex,and somatometric parameters among school age children. Methods: A cross sectional study was done on 947 apparently healthy subjects (496 boys and 451 girls) aged 6 - 17 years. The subjects were recruited from some primary and secondary schools within Nsukka metropolis and also from out patients in the study centre. A pilot study was done to determine the intra- and inter rater reliability of sonographic measurements of the spleen. The sonographic examination was performed on Shenzhen DP-1100 machine with 3.5 and 5 MHz convex transducers. Spleen sizes were obtained with the subject in a right lateral decubitus position. Results: Measurement of spleen length was reliable while measurement of spleen width was less reliable within and between sonographers. Dimensions of the spleen were not statistically different in boys and girls (p > 0.05). Height correlated best with spleen dimensions. Conclusion: Normogram of the spleen size with respect to height is important in the determination of some pathology associated with changes in its size
