Export potential of ornamental live fishes in Nigeria

Nigeria is blessed with an abundant variety of fish species, some of which have been exported over the years. These fish species are taken either from the wild or cultured. Large quantities of fishes and fishery products are exported from Nigeria in different forms and which have been sources of foreign exchange earnings for the Country. An estimate value of exports in the fishery sub-sector stood at approximately U.S. $48.212,070 for shrimps/sole fish/cuttlefish/crabs and over U.S.$500,000 for ornamental live fishe

Social Ecology and Urban Green Spaces in Ibadan, Nigeria

This study analyses and explains the spatial pattern of urban green spaces based on a new approach, the application of the concept of social ecology with data collected from 3410 respondents selected across the 104 communities in Ibadan using stratified random sampling technique of projected population of Ibadan for 2015 estimated at 1,783, 367 with four sample percentages, 0.1% 0.2%, 0.4% and 0.8 % respectively. Bivariate correlation analysis of SPSS version 21 was used to determine the significant social ecology indicators at P ≤ 0.05. Results show that the spatial pattern of green spaces was clustered indicating an uneven distribution of the benefits and burdens of urban green spaces for the year 2015. There are significant relationships between green spaces occurrence and such social ecology indicators as occupation (P = 0.001), income (P = 0.002) and housing type (P = 0.002). Thus, the distribution of green spaces is a function of the various social structures in existence in the metropolis. The commonly used indicators for social ecology in the literature for geographical studies are income, race and education. This study identified two additional possible indicators: occupation, and housing type.Keywords: social ecology, urbanization, green spaces, GI

Analysis of the Sensory Attributes Of Plantain Wine: An Alternative to Imported Wines in Nigeria

This study was carried out at School of Agriculture, Lagos State Polytechnic and the data were analyzed at Statistics department, The Polytechnic, Ibadan. Plantain is locally available all year round especially during the period of November – February. There is over supply of it to the extent of some getting over- ripe and are wasted. Yet, the over-ripe one could be utilized for the production of wine. The alcoholic content of such a wine is adjustable to individual requirement. Respondents for the microbial analysis of the product were drawn from Ikorodu and South West of Ibadan areas. The study tends to conclude that the wine can complete favourably with foreign wines. It can be taken by both the young and old, during meals and even at parties or special occasions. The product over-all can be said to have passed the consumers’ assessment in terms of the attributed consideration. The result showed that the respondents are from South West areas of Nigeria. It is thus expected that the other consumers in this population will react in the same way as the respondents to the product. The acceptability of the production in the society is therefore not in doubt and the results from this study can be used to allay public fear of its safety and to enhance the acceptability of the product. It is recommended from the analysis of variance table that further research work should be carried out using other local materials as flavour to preserve the wine in order to reduce importation of wine and also promote economic growth and development.

Geospatial Analysis of Road Traffic Accidents, Injuries and Deaths in Nigeria

RTAs in Nigeria are very high and have become progressively important because of their heavy health and financial burden. The few geographic studies on RTAs in Nigeria are limited to their mere spatial distribution and associated risk factors, with very little attention given to their spatial clustering patterns and the detection of hotspots. With the aid of Global Moran’s I and Local Getis, the study found some evidence of significant positive spatial autocorrelation, and consistent clustering of RTAs, RTIs and RTDs in the southwest from 2002 to 2007 which suggested the presence of an accident belt in the southwestern region, which has been accounted by poor road infrastructure, relatively high level of economic development and high vehicular movements. The study recommends the deployment of road safety officials to the accident belt, strict enforcement of safety belts and helmets, and periodic road maintenance

Relationships between vegetation gradients and soil variables of mangrove swamps in southeastern Nigeria

The vegetation and soils of mangrove swamps were studied in order to determine the relationship between species variation and soil variables. The basic premise was that the vegetation and the soils are multivariate and could be viewed in terms of gradients. Principal components analysis, an eigenvector multivariate analytical technique, was used in the interpretation of the structure within the correlation matrix of the vegetation and soil data. The principal components analysis indicated the first four components of the soil system as: salinity (complex hydrochemical gradient); nutrient gradient; soil moisture gradient; and substrate texture gradient. The first four components of the vegetation system were indicated as: competition gradient; adaptation gradient; residual competition gradient; and site preference gradient. The soil salinity gradient was negatively correlated with vegetation competition and adaptation gradients (r= - 0.38; r= - 0.35), while the nutrient gradient was positively correlated with the residual competition gradient (~0.56). It was observed that non-mangroves were more sensitive to soil nutrient levels than true mangrove species

Correlation and Path Coefficient Analyses of Yield in Cacao (Theobroma cacao L.)

Cacao (Theobroma cacao L.) is an important commodity tree crop which produces the cocoa bean, a major source of income for most West African countries and many smallholder farmers. Declining yield of cacao is a major limitation to cocoa production in Nigeria. This study aimed at determining the correlations of the phenotypic traits that were related in the yield of the cacao genotypes. Nine cacao hybrids produced from some high-yielding parents in the research farm of Cocoa Research Institute of Nigeria, Ibadan, Nigeria were evaluated from 2012 through 2017 in Owena (7°11’ N, 5°1’ E), Ondo state, Nigeria. Character Correlations and Path Coefficient Analysis were used in the description of the performance of the genotypes. The study concluded that significant genotypic and phenotypic correlations existed among many of the pairs of the fruit and bean characters with one another and with pod index, suggesting a complex contribution of these characters either positively or negatively to growth and yield in cacao, and that fruit and bean traits are determinants of yield in cacao

Bumpy or smooth road ahead in compliance with European Union regulations? Challenges and opportunities for smoked catfish export from Nigeria

Trade in smoke dried fish is driven by demand from Africans in the European Union (EU) and United States.The EUhygienepackage follows the principles ofthe farm to table promoted by the World Trade Organisation (WTO) andwasdesigned to protect the health and safety of consumers as well as addressing animal welfare, plant health and environmental protection.Nigeria canexport all forms of fishery products to the EU community except aquaculture products.EU rules have become more stringent and in the case of aquaculture products include compliance with raw material traceability, existence of an aquacultureresidue plan on heavy metals, contaminants, pesticides and veterinary drugs. Presently, the country is still in the process of adopting requirements to meet the EU regulations on quality control for farmed products.This paper is exploratory in nature and focuses on the smoked catfish export being mostly an aquaculture produce. Large consignments of smoked fish have been rejected due to mould growth, insect infestation, inappropriate packaging and occurrence of contaminants. Huge public investment is required for setting up a certification system and update administrative provisions, monitoring technologies and sanitary control. Consideringthis, Nigeria is challenged with inadequate technical infrastructure for environmental management of aquaculture. Therefore, what are implications for small-scale commercial catfish farms and fish processors in smoked catfish export in overcoming these technical barriers within a short period?What should be the roles of the State and regulatory agencies in surmountingthese obstacles

CAUSAS QUE DETERMINAN LAS DIFICULTADES DE LA INCORPORACIÓN DE LAS TIC EN LAS AULAS DE CLASES - Causes that determine the difficulties in the onboarding process of ICT in classrooms

Las dificultades presentadas por los docentes en implementar las TIC, en el proceso de enseñanza y de aprendizaje en las aulas de clases de las instituciones educativas de la ciudad de Riohacha – La Guajira, han transformado la forma de educar, requiriendo el desarrollo profesional del profesor en un entorno tecnológico que facilite la creación de nuevos ambientes educativos mediante el uso de estrategias pedagógicas en las aulas de las instituciones educativa.  El propósito del presente artículo fue analizar los factores que determinan las dificultades de la incorporación de las TIC en las aulas de clases. El sustento teórico estuvo respaldado en varios autores como Riveros y Mendoza, (2008), Monsalve (2015), Touriñán (2007), UNESCO (2013), Coll (2007), entre otros. Es un estudio de tipo descriptivo, con diseño no experimental y de campo, se utilizó la técnica de la encuesta personal, trabajo de campo y observaciones dentro de las instalaciones educativas. Llegándose a la conclusión que se requieren de unos espacios físicos adecuados y los equipos tecnológico actuales, no son suficiente para la demanda de las exigencias de los docentes y estudiantes, no existen recursos económicos suficientes para adquisición, mantenimiento, para la capacitación continua y permanente en TIC, lo cual hace que muchos docentes se rehúsen a usar las nuevas tecnologías educativas
