Efecto de las características socioeconómicas de los agricultores de invernaderos en la producción de verduras en el estado de Ogun, Nigeria

In Nigeria, vegetable production is adversely affected by climate change, pest and diseases attack and unfavourably environmental condition which have made resourceful farmers and government to embark on vegetable production under greenhouse technology. Hence, this study was conducted to assess socio-economic importance of greenhouse technology for sustainable vegetable production in Ogun State, Nigeria. The specific objective is to identify major limitations to the practice of greenhouse vegetable in the study area. One hundred and twenty (120) vegetable farmers were purposively selected for this study. Data were collected using well-structured interview guide and analyzed with descriptive statistics and chi-square analysis. The results showed that the respondents were 32 – 40 years of age; predominantly male (90.8%), and had formal education (28.3%). Socio-economic importance of greenhouse technology includes increased yield (94.3%), available supplies all the year round (85.7%), and higher income generation (75.7%). Paradoxically, greenhouse vegetable production has not been widely spread due to difficult to establish it by individuals and high cost of construction (98.3%). So also, chi-square results showed that significant relationship existed between the major limitations and socio-economic importance of greenhouse technology at p < 0.05 level of significance. This study recommends that cost of raw materials for constructing greenhouse should be subsidized by the Federal Government of Nigeria while wealthy individuals, farmers’ groups and cooperative societies should invest in greenhouse technology for large scale vegetable farmingEn Nigeria, la producción de hortalizas se ve afectada negativamente por el cambio climático, el ataque de plagas y enfermedades y las condiciones ambientales desfavorables que han hecho que los agricultores y el gobierno ingeniosos se embarquen en la producción de hortalizas con tecnología de invernadero. Por lo tanto, este estudio se realizó para evaluar la importancia socioeconómica de la tecnología de efecto invernadero para la producción sostenible de hortalizas en el estado de Ogun, Nigeria. El objetivo específico es identificar las principales limitaciones a la práctica de hortalizas de invernadero en el área de estudio. Ciento veinte (120) productores de hortalizas fueron seleccionados deliberadamente para este estudio. Los datos se recopilaron mediante una guía de entrevista bien estructurada y se analizaron con estadísticas descriptivas y análisis de chi-cuadrado. Los resultados mostraron que los encuestados tenían entre 32 y 40 años de edad; predominantemente masculino (90.8%), y tenía educación formal (28.3%). La importancia socioeconómica de la tecnología de efecto invernadero incluye un mayor rendimiento (94.3%), suministros disponibles durante todo el año (85.7%), y mayor generación de ingresos (75.7%). Paradójicamente, la producción de hortalizas de invernadero no se ha extendido ampliamente debido a la dificultad de establecerla por parte de los individuos y el alto costo de construcción (98.3%). Así también, los resultados de chi-cuadrado mostraron que existía una relación significativa entre las principales limitaciones y la importancia socioeconómica de la tecnología de invernadero con un nivel de significancia p<0.05. Este estudio recomienda que el gobierno federal de Nigeria subsidie el costo de las materias primas para la construcción del invernadero, mientras que las personas adineradas, los grupos de agricultores y las sociedades cooperativas deberían invertir en tecnología de invernadero para el cultivo de hortalizas a gran escal

Emergence and spread of two SARS-CoV-2 variants of interest in Nigeria.

Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants of interest in Nigeria and the wider Africa region. By integrating travel data and phylogeographic reconstructions, we find that these two variants that arose during the second wave in Nigeria emerged from within Africa, with the B.1.525 from Nigeria, and then spread to other parts of the world. Data from this study show how regional connectivity of Nigeria drove the spread of these variants of interest to surrounding countries and those connected by air-traffic. Our findings demonstrate the power of genomic analysis when combined with mobility and epidemiological data to identify the drivers of transmission, as bidirectional transmission within and between African nations are grossly underestimated as seen in our import risk index estimates

Effect of Socio-economic Characteristics of Greenhouse Farmers on Vegetable Production in Ogun State, Nigeria

In Nigeria, vegetable production is adversely affected by climate change, pest and diseases attack and unfavourably environmental condition which have made resourceful farmers and government to embark on vegetable production under greenhouse technology. Hence, this study was conducted to assess socio-economic importance of greenhouse technology for sustainable vegetable production in Ogun State, Nigeria. One hundred and twenty (120) vegetable farmers were purposively selected for this study while descriptive statistics and chi-square analysis were used for the data analysis. The results showed that the respondents were 32 – 40 years of age; predominantly male (90.8%), and had formal education (28.3%). Socio-economic importance of greenhouse technology includes increased yield (94.3%), available supplies all the year round (85.7%), cluster marketing formation (72.9%), higher income generation (75.7%), and rural development (91.4%). Paradoxically, greenhouse vegetable production has not been widely spread due to difficult to establish it by individuals and high cost of construction (98.3%); it is too expensive for the low peasant vegetable farmers (86.7%); and awareness of greenhouse vegetable is low in the public markets (85.8%). So also, chi-square results showed that significant relationship existed between the major limitations and socio-economic importance of greenhouse technology at p < 0.05 level of significance. This study recommends that cost of raw materials for constructing greenhouse should be subsidized by the Federal Government of Nigeria while wealthy individuals, farmers' groups and cooperative societies should invest in greenhouse technology for large scale vegetable farming
