Item Agricultural labour productivity growth and food insecurity transitions among maize farming households in rural Nigeria(University of Belgrade Faculty of Agriculture, Serbia., 2022) Adepoju, A. O.; Obialo, C. A.Agriculture in rural Nigeria is labour-intensive. Thus, the much-desired transition from food insecurity to food security by households requires growth in labour productivity. Labour productivity growth and its effect among other factors on food security transitions of maize farming households in rural Nigeria were assessed. Food insecurity indices were constructed using the second and third waves of data from the General Household Survey- Panel (2012 and 2015), and a probabilistic model was specified. The analytical tools used were descriptive statistics, Partial factor (labour) productivity, Foster- Greer-Thorbecke Model, Markov chain model, Tobit, and Multinomial Logit Regression Models. Labour productivity increased between the two periods although labour productivity growth was very low. Labour productivity growth negatively and significantly affected the transition into food security and being chronically food insecure. Thus, a boost for labour productivity growth should be targeted as a safety net, especially for the food insecure and households vulnerable to food insecurity.Item Are small-scale poultry farmers aware of aflatoxin contaminants in feed in Oyo State, Nigeria?(2022-12) Adepoju, A. O.; Obi, U.; Jerumeh, E.Aflatoxins, feed contaminants formed by certain moulds occur naturally as feed and food impurities and have toxic consequences on both animals and humans. Earlier studies on aflatoxins in Nigeria did not consider small-scale poultry farmers’ awareness of feed contamination. Thus, this study examined the level of awareness of flatoxins in poultry feed and its determinants. Descriptive Statistics and the Logistic Regression Model were the analytical tools employed to analyse data collected from field survey in 2019. One-third of the farmers were aware of aflatoxins in feed which depicts that the level of awareness of aflatoxin in feed by the poultry farmers in the study area is low. Years of education, primary occupation, farm-scale, years of farming experience, access to information from research institutions, and membership in cooperative societies were among the key determinants of the awareness of aflatoxin in feed by the farmers. Efforts should be geared towards increasing the level of awareness of the farmers on the highly toxic contaminant even when fed to poultry at non-fatal levels. Agricultural information highlighting the detrimental consequences of aflatoxin on the health and productivity of poultry and how to minimize aflatoxin contamination in feed should be made more accessible to all farmers.Item Post-harvest loss along the watermelon value chain in the tropics(Taylor & Francis, 2021) Adepoju, A. O.; Ologan, O.The growing realization of nutritional and health benefits, and the potential of watermelon (Citrullus lanatus L.) as a cash producing crop has renewed interest in reducing loss in its postharvest handling. Information on the extent of loss in different parts of its post-harvest system under tropical conditions is scarce. Key constraints identified by producers were insect infestation, insufficient working capital, poor handling of produce, lack of access to market, and lack of technology while inadequate access to funds, lack of storage facilities, and poor packaging of produce were identified by marketers. Post-harvest trouble spots were determined through adequate evaluation of the proportion of loss and associated factors along the watermelon supply chain. The majority of producers and marketers experienced loss of up to 40%, some >60%. Interventions in trouble-spots can have an impact on the reduction of postharvest loss. A better understanding of loss along the supply chain was developed which can lead to the determination of effective strategies to manage watermelon loss in the tropics.Item Effect of workdays lost to presumptive malaria on households’ poverty status among food crop farming households in rural South West, Nigeria(Department of Agricultural Economics and Extension, Prince Abubakar Audu University, Anyigba, Kogi State, Nigeria, 2020) Adekanye, J. O.; Adeoti A. I.; Adepoju, A. O.; Awoyemi, T. T.This study examined the influence of Workdays Lost to Presumptive Malaria (WLPM) on poverty status of Food Crop Farming Households (FCFHs) in rural South West, Nigeria. The primary data were collected with well-structured questionnaire administered on 395 FCFHs randomly selected using multistage sampling technique. Data were analysed using descriptive statistics, Foster-Greer-Thorbecke and two stage probit least square regression model at α0.05. The results show that 88.6% of the households were male-headed, age was 56.41 ±9.34 years. Years of schooling and farming experience were 4.80±4.65 and 29.53 ±10.78, respectively. Only 37.2%, 45.1% and 24.6% have access to electricity, extension services and agricultural credit, respectively. The annual farm income was N452,711.70±153,704.70 (equivalent to N37,725.97 per month). In a year, an average of 73.49 workdays (valued at N58,358.5) was lost to presumptive malaria per household. The Mean Per Capita Household Expenditure (MPCHE) per month was N5,605.89, the poverty line (i.e 2/3 of MPCHE) was N3,737.26. FGT model results indicate that poverty incidence, depth and severity were 0.425, 0.031 and 0.004, respectively. The incidence of poverty increased with increased in WLPM. In the 2SPLS analysis, the coefficient of WLPM was positive (β=0.0607) and statistically significant (p-value = 0.049), implies that increase in WLPM increase the probability of households being in poverty. The result of the Wald test of exogeneity suggests that the WLPM is truly endogenous to household poverty status. Therefore, WLPM had an increasing effect on poverty status of the respondents. The study recommended that, poverty interventions should adequately incorporate strategies on malaria prevention and control; and be extended to rural areas as a way of poverty reduction among rural populace. Also, the national health insurance scheme needs to incorporate rural farming households and people in the informal sector to reduce the out-of-pocket spending on malaria treatment as a poverty reduction strategy.Item Productivity and market participation of Fluted pumpkin farmers under tropical conditions(Talor & Francis, 2020) Adepoju, A. O.; Oyegoke, O.; Amusan, A.Increased productivity and participation of farmers in the market are pertinent for improved farm incomes. Factors affecting participation for Fluted Pumpkin (Telfaria occidentalis Hook F.) are lacking. Factors influencing productivity and market participation among 200 Fluted Pumpkin farmers were examined. An ordinary least squares regression model indicated farm size, use of seed of improved varieties, and years of education, positively influenced productivity; quantity of seed and fertilizer use negatively influenced productivity. Most farmers were productive. Fluted pumpkin farmers participated in the market to a high degree. Improved participation of farmers in the market appears to be based on gender, marital status, level of education and market experience. Drivers of productivity and participation of Fluted pumpkin farmers are important for enhanced, sustainable, production, to meet increasing demand and exploring the potential as an exportable crop.Item Characterisation of indigenous helmeted guinea fowls in Nigeria for meat and egg production(2021) Shoyombo, A.J.; Yakubu, A.; Adebambo, A. O.N.; Popoola, M. A.; Olafadehan, O. A.; Wheto, M.; Alabi, O. O.; Osaiyuwu, H. O; Ukim, C. I.; Olayanju, A.; Adebambo, O. A.There is increasing interest in sustainable poultry production in developing economies. This review provides an insight into guinea fowl production in Nigeria as a means of additional high-quality poultry meat and egg production. Under the smallholder scavenging system, flock size of the four investigated plumages (Pearl, Lavender, Black and White) of indigenous helmeted guinea fowl in Nigeria typically ranges from 6 to 9 birds per household, 14-week mean live weight from 917 to 975 g, dressed weight at this age from 700 to 737 g and dressing percentage from 74 to 76%. Under the back yard system of production, mean egg number is typically about 80 eggs per hen/annum while under intensive management it can be up to 147 eggs per hen/annum and egg weight from 29 to 38 g. Under smallholder conditions, hatchability of fertile eggs can range from 70 to 86% while under improved housing and rearing conditions it can be as high as 89%. The present information could be exploited in formulating appropriate management strategies and breeding decisions for sustainable production of hybrid improved guinea fowls,thereby contributing to food security in Nigeria.Item Floristic structure of some selected plots in olokemeji forest reserve, Ogun state, Nigeria(2021) Olubode, S.O.; Taiwo, D.M.; Woghiren, A.I.Deforestation disrupts forest structure and function with negative impacts on biodiversity and natural regeneration of the forests. In Nigeria, forests are lost through burning, shifting cultivation and logging of trees. These describe the state of degradation in Olokemeji forest reserve. Hence, a need to evaluate the species composition and floristic structure of the woody species in selected plots of the forest reserve. The forest reserve, situated in the lowland rain forest of south-western Nigeria occupies a total land area of 58.88 km2. Six sample plots of 50 m2 each were randomly selected and designated as Frequently Burnt Plot 1, frequently burnt Plot 2, Harvested Plot, Unharvested unburnt Plot, Arable Plot 1 and Arable Plot 2. One hundred and eighty two stands were enumerated, with unharvested unburnt plot having the highest number of trees at 50. The highest percentage cover was recorded at frequently burnt plot 1, frequently burnt plot 2 and Unharvested unburnt plot which ranged from 21-50%. Trees in Unharvested Unburnt Plot had the highest mean diameters at breast height (78.46cm) and mean heights (14.44 m), while the Arable Plots had lowest mean diameters at breast height and mean heights. There is a high level of anthropogenic interference at the forest reserve, and the structure and composition of the tree species enumerated in the study plots reflected some of the nature of impact. Indiscriminate logging of trees as fuelwood should be greatly curtailed and improvised by the neighbouring communities.Item Nutritional Vulnerability Transitions among Rural Households in Nigeria(2023) Adepoju, A. O.Aims: It has long been considered that specific age/gender groups, such as women and children, are predisposed to nutritional vulnerability. Thus, nutritional vulnerability among agricultural households is neglected and understudied. This study aims at an empirical assessment of nutritional vulnerability dynamics among rural households in Nigeria. Study Design: Secondary data used for this study was waves 2 and 3 of the general household survey panel data. The sampling design consisted of two stages of sampling: the selection of enumeration areas based on probability proportionate to the size of the enumeration areas and the systematic random selection of ten households from each enumeration area. There were 3370 households selected in rural areas and 1630 households selected in urban areas. 2090 rural households with the required information for this study were included in the analysis. Methodology: Descriptive statistics, nutritional vulnerability score, logit regression model, Markov model, and multinomial logit regression models were used to analyse nutritional vulnerability transitions among rural households in Nigeria. Results: Nutritionally vulnerable households in rural Nigeria include those with aged heads, little or no formal education, limited assets, and no access to land or credit. Nutritional vulnerability in rural Nigeria is primarily transient, with around two-fifths of households experiencing transient nutritional vulnerability and nearly one-third experiencing chronic nutritional vulnerability. While the age of the household head, tertiary education, and access to credit all had a substantial impact on transient nutritional vulnerability, gender, tertiary education, asset value, and access to credit all had an impact on chronic nutritional vulnerability. Conclusion: Support mechanisms such as initiatives to promote access to healthy food, credit, land, and education are critical. To successfully address the issues affecting the nutrition and health of persons facing vulnerabilities, social welfare programs with interventions based on the characteristics of each vulnerable group and the predisposing factors should be adopted.Item Gender Differentials in Educational Attainment in Rural Nigeria(Macrothink Institute, 2022) Adepoju, A.O.; Chibueze, O.; Ibitola O.R.Education, identified as the substratum of any serious nation’s growth and development, is regarded as an instrument for social change, as well as the process of preparing an individual to become a functional and acceptable member of society. It also ensures the character and moral development of the young learners and the development of sound attitudes for both genders. This study examined gender differentials in educational attainment in rural Nigeria, employing the t-test, analysis of variance and the ordinary least squares regression model for analysis. The main factor which had negative effects on educational attainment of female-headed households was the cost of schooling while factors such as the organization running the school and means of transportation had positive effects on the educational attainment of female households. On the other hand, while age and occupation of the household head had negative effects on male educational attainment, factors such as the value of asset, the organization running the school and means of transportation had positive effects. The approval and implementation of necessary legislation and policies on education targeted at rural dwellers is of utmost importance. This could center on the provision of more nearby government-owned schools as well as awareness creation on the essence of educating both genders, especially the girl child, with a focus of achieving gender balance in educational attainment.
