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.
Analysis of Edible Snail (Archachatina margtnata) Marketing in Ibadan Metropolis, Oyo State, Nigeria
(International journal of applied research and technology, 2012) Adenegan, K.O.; Bolaji-Olutunji, K.A.
The study examined the marketing efficiency, profitability and the factors contributing to the profitability of snail marketing in Oyo State Nigeria. Forty copies of questionnaires were administered in five major markets in Ibadan (Aleshinloye, Oje, Orita-merin, Bodija and Apata markets). Simple descriptive analyses such as percentage and frequency table were used to describe the socio-demographic characteristics of the respondents while multiple regression analysis was used to examine the determinants of profitability of snail marketing. It was discovered from the empirical result that 90% of the sellers were female while 10% were male. One hundred percent (100%) of the sellers were 20years of age and above, and have 10 or more years of experience, 37% had no formal education while 40% had primary education and 23% had secondary education. The average profit N24, 250 forms the Budgetary Analysis (Av.selling price -Av.cost price) while the marketing efficiency for different markets are 1.98, 1.54, 1.19, 1.25 and 1.60 for Aleshinloye, Oje, Oritamerin, Bodija and Apata respectively. Four regression functions (Linear Function, Semi log, double log and Exponential Function) were run to analyze the determinants of snail marketing profitability. The exponential function provided the best of fit equation because it has more significant variables, highest coefficient of multiple regression, R\0.66) and lowest DurbinWatson, DW (l.473).The marketing of Snail can be said to be profitable, efficient and sustainable. It can reduce poverty. Therefore, further research should be carried out to domesticate and rear more edible snails in Oyo State and Nigeria as a whole to get more supply of protein and calcium in our diets.
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.
Are tomato farmers willing to adopt the hydroponics farming system in Oyo State, Nigeria?
(University of Maribo Press, 2023) Adepoju, A. O.; Adekunle, O.
The rising demand for tomatoes and tomato-based foods in Nigeria owing to its numerous health benefits calls for a comprehensive and economically viable farming system to replace or complement traditional farming systems for tomato production. This study therefore assessed the level of awareness of tomato farmers and their readiness to adopt the hydroponics farming system. The sociodemographic determinants of their readiness to adopt hydroponic farming were also identified. Measures of central tendency and the logistic regression model were employed in the analysis of data. Knowledge of hydroponic farming was low among the farmers. Key positive determinants of awareness include distance to market, having government support and access to social media. More than three-fifths of the farmers were willing to adopt the hydroponics farming system. Such farmers had tertiary education, access to extension agents and relatively small farm sizes. High initial capital for adoption was the most critical limitation to the readiness of adoption of the system. Enhanced tomato output from this system may be a cause for its advocacy. Awareness and adoption of hydroponic farming can be increased if extension services are intensified. This will ensure food security and sustainable economic development.
Cassava Productivity Growth in Nigeria
(2019) Oluwafemi1, Z. O.; Omonona, B. T.; Adepoju, A. O.; Sowunmi, F. A.
Cassava has gained prominence in the world and has become economic crop in the Nigerian agricultural sector. Secondary data was used for this study. The required variables were extracted from General Household Survey Panel Data (GHS-P). The GHS-P is a nationally representative survey of households across Nigeria covering urban and rural sectors. Analytical tools used included Total factor productivity and Markov chain. 82% of populations of Cassava farmers are in the rural areas and close to 73% were young adults including both male and female involved in cassava production. Approximately 65% of the cassava based farmers were single that not yet married and most of the farmers were educated and about 80% and 98% of the cassava based farmers did not have access to credit facilities and extension personnel respectively. Generally, the cassava productivity growth was erratic and very small proportion of cassava farmers that were in lower productivity reduced overtime, while the minimal proportion of cassava farmers that moved into both moderate and high productivity increased overtime respectively. Generally, there is more to be done to increase and attain sustainable high level cassava productivity growth in Nigeria.
Community Participation in Rural Development: A Case for Environmental Assessment.
(International journal of environment and development, 2000) Fawehinmi, A.S.; Akinterinwa, K.O.
In the face of the popularity of sustainable development, rural development must have an environmentally - friendly posture-thus the need for environmental assessment of proposed projects. This paper makes a case for community participation in environmental assessment addressing the obvious advantages therein. It asserts that the low level of community participation in environmental assessment may have a negative effect on the effectiveness of the performance of the project. It finally makes a call for proper legislation that will give the community a greater and higher level of participation in environmental assessment.
Consumption pattern and demand analysis of dacryodes edulis in Umuahia metropolis of Abia State
(Proceedings of the 37th annual conference of the forestry association of Nigeria held in Minna, Niger State, 2015) Adenegan, K.; Olowoyo, F.B.; Ajewole, o. i.; Koyejo, 0.A.,; Okelola, O.E; Akinyemi, G.0.; Nwachukwu, I.C.
Consumption pattern and demand analysis of Dacryodes edulis commonly called ube by the Igbos in Umuahia, Nigeria was studied. The various uses and reasons for consumption of Dacryodes edulis, socio- economic characteristics of respondents, income elasticity, regression of the significance of socio-economic variables on demand for Dacryodes edulis, correlation of socio-economic status and consumption are addressed. Simple random sampling was adopted. A well structured questionnaire were used for Dacryodes edulis consumers at the household in two selected local government areas in Umuahia. A total of (160) one hundred and sixty questionnaires were administered, on a total of eight (8) villages. Data obtained were subjected to simple descriptive statistics, which shows that almost all the respondents (92.0%) consume Dacryodes edulis and they got to know of Dacryodes edulis through family and friends due to its high medicinal value as claimed by 91.3% of the respondents. Results indicated a significant descriptive (p<0.05) contribution of the inde~ndent variables on the quantity of Dacryodes edulis consumed. The coefficient of determination (R) which is 58% makes the model fitted well to the data. The marital status has the highest contribution (0.179) to the quantity of Dacryodes edulis consumed, this is followed by willingness to buy (0.167), how often (0.137), household size (0.116), age (0.1(0) educational level (0.099), price of purchase (0.095) and profession (0.068).The income elasticity of Dacryodes edulis demand is 13%. The income elasticity is significant at 5% with coefficient of 0.13, this means that a percent increase in income leads to a 13%, of change in Dacryodes edulis consumption. The correlation shows that the quantity purchased and how often you buy Dacryodes edulis is significant (-0.5807) and also the quantity purchased and price quantity of purchase each time is also significant (0.6440).
The consumption pattern of goat meat in Ilorin metropolis of Kwara State, Nigeria
(International journal of sustainable development, 2011) Nwauwa, L.O.E.; Akintunde, O.K.; Adenegan, K.O.
Goat is a multi-purpose animal whose uses range from consumption, companionship to commercial meat production. Its production and consequent consumption is widely accepted in Nigeria among the different ethno-religious sects unlike pig, dog and donkey. The paper examined the factors that affect consumption pattern of both kid and mature goat meat in Ilorin metropolis of Kwara State, Nigeria. Primary data were collected from 150 consumers of goat meat through the use of structured questionnaires. The data were analyzed using descriptive statistics and multinomial logit model. The study results showed that 10% of the respondents in the study area consumed both kid and mature goat meat, while the remaining 20% and 70% consumed the kid goat only and mature goat meat only categories, respectively. Tenderness and unpalatable nature of the kid goat meat were found to reduce its demand. The results obtained also showed that the number of the dependants of consumers significantly influenced consumers' preference for the goat meat consumed. The likelihood ratio for the model, lambda (A) is 16.9 which is significant at 5% level. This implies that the goat meat consumer groups are heterogeneous. The multinomial logistic estimate for the combined goat meat consumer groups revealed that income and number of dependants of respondents were significant and therefore explained why individuals prefer to consume either the combination of kid and mature goat meat or the mature goat meat instead of the kid goat. The educational status of respondents and price of other meat products were not significant and therefore did not significantly influence individual's preference for a combination of kid and mature goat meat or only mature goat meat, instead of consuming the kid type of meat only. The study therefore recommends that efforts should be "lade to create awareness of the dangers of consuming meat with high cholesterol content which has been linked to cause many diseases coupled with training of butchers and goat meat processors on modern methods of processing cholesterol-free meat for healthy consumption.

Contribution of non-timber forest products (ntfps) utilization to the well-being of women: evidence from Nigeria
(Faculty of Agriculture, University of Ruhuna, Sri Lanka., 2021) Adepoju, A. O.; Adewale, A. A.; Jayeola, O. B.
This paper assessed the contribution of NTFPs to the well-being of women living in Ewekoro Local Government Area of Ogun State, Nigeria. Logistic regression and Ordered Logistic regression models were used to assess the contribution of NTFPs to the well-being of 120 women in the study area. The mean age, monthly household income, distance of homestead to forest and homestead to the nearest market were 47 years, $144.4, 2.0km and 1.8km respectively while 70.5% of the women used NTFPs as food. The housing dimension had the highest index of 0.537 while the overall index of 0.491 indicates a moderate level of well-being for respondents. NTFPs utilization significantly increased with household income and primary occupation but decreased with increasing age, level of education, distance from homestead to forests, distance to the nearest market and access to credit. Women’s well-being increased with utilization of NFTPs, being married, distance from homestead to the nearest market and access to credit but decreased with the distance of homestead to the forest, association membership and income. It is recommended that agricultural advisory and extension services in terms of NTFPs collection and utilization be provided; unconditional cash transfers and other consumption smoothening aids should be provided; necessary road networks should be rehabilitated or constructed, this will enhance NTFPs utilization; credit access should be provided for rural women, and rural women should be mobilized to form and/or join associations. Given that, NTFPs utilization contributes to the well-being of women, policies and programs that will enhance women’s utilization of NTFPs should be put in place.
Credit utilisation among rice farmers in Oyo state, Nigeria
(Journal of sustainable development, 2010) Oladokun, Y. O. M.; Adenegan, K. O.
Assessment has to be made: (ii) assessment of a bank's performance involves both quantitative and qualitative factors; (iii) there is the problem of identifying banks' inputs and outputs; and (iv) the existence of several heterogeneous ,inputs and outputs. That cannot be easily compared. The study makes use of Data Envelopment Analysis in an attempt to measure the relative efficiency of commercial banks. It was observed that inefficiencies link more to inefficient resource utilisation rather than production scale. Also, Nigerian Banks were noted to be highly operationally inefficient. Hence, it is not sufficient to increase the capital base but it is important to make the environment more competitive, and to improve the absolute efficiency of the industry.
Demand, Supply Response and Preference Switch for Rice in Nigeria
(2014) Ayanwale, A. O. S.
The phenomenon of increasing rice importation defying several policy interventions has been of great concern in Nigeria. This rising importation is however driven by increasing demand, shortage in domestic supply and consumers’ preference for imported rice. Yet, comprehensive national studies on determinants of demand, supply response and preference switch for rice are scarce. Thus, the determinants of demand, supply response and preference switch for rice were investigated. Secondary data from the Nigeria Living Standard Survey (NLSS) of 2004 conducted by the National Bureau of Statistics (NBS) and time series data from the official records of International Rice Research Institute (IRRI), 1960-2008 were used. Due to elimination of households with missing values on variables of interest, a total of 18,861 out of 21,900 households were used in the NLSS. Variables used in NLSS included Household Size (HS), Non-Food Total Expenditure (NFTE), Years of Education (YE), sector (urban/rural), occupation (farming/non-farming) and Membership of Association (MA) which were hypothesized to influence household expenditures on Imported Rice (IR), Improved Domestic Rice (IDR) and Local Rice (LR). Data on area cultivated, level of import, fertilizer consumption and prices were used in IRRI rice statistics and these variables were also hypothesized to influence supply (output) of rice. Data were analysed using descriptive statistics, Tobit regression model, vector error correction model and generalised least square regression at p= 0.05. The HS and YE were 4.9±2.9 and 6.8±6.3 years, respectively. Rural dwellers, farmers and members of association constituted 76.1%, 82.7% and 54.2%, respectively. Monthly rice expenditure was N2, 712.40, representing 25.0% of total monthly food expenditure. The expenditure share of IR (45.0%) was higher than IDR (30.0%) and LR (25.0%). Urban sector, YE, HS and NFTE increased the demand for IR by 4.0×10-03, 2.0×10-04, 1.0×10-03 and 1.0×10-09, respectively, while Farming Occupation (FO) reduced it by 9.0×10-03. Also, FO increased IDR demand by 8.0×10-03. Conversely, HS, NFTE, and MA reduced IDR demand by 9.0×10-04, 2.0×10-08 and 1.0×10-09, respectively. Also, NFTE and MA, respectively, increased LR demand by 6.0×10-09 and 4.0×10-03. Price elasticities of IR, IDR and LR which were -3.0×10-03, -7.0×10-04 and -2.0×10-03, respectively implied that rice was price inelastic. Also, income elasticities of IR, IDR and LR which were, respectively, 7.0×10-08, 2.0×10-07 and 1.0×10-07 classified rice as ‘necessities’ and ‘normal’ good. In the long-run, area cultivated and fertilizer consumption increased rice output by 2.8 and 2.3 respectively. Rural Sector (RS), HS, FO, and price of IR increased consumers’ switch from IR to IDR by 55.1, 6.6, 130.4, and 30.7, respectively, while price of IDR reduced it by 19.4. Price of IR and RS positively influenced switch from IR to LR by 2.0 and 70.2, respectively, while price of LR reduced it by 16.3. Education and urban livelihood increased demand for imported rice. Increasing rice area cultivated and usage of fertilizer may boost domestic rice supply. Price reduction will be a veritable tool in switching consumers’ preference from imported to improved domestic and local rice.
Determinants

"Regression model was used to analyse the volume of maize offered to the market for sale. The result of the Tobit model correctly predicted 67% of the observation with a significant chi square of 52.93 and it shows the overall significance of the model. All variables had positive coefficients significantly differ from zero except years of education, transaction cost, marital status and household size. This means that a unit increase in the quantity of these variables will increase the proportion of maize offered for sale by the respondents. The, result of the regression model also showed that R -Square and adjusted R-Square are respectively 5 % and 90% with a significant overall fit. Volume of maize sold by individual respondents was used as the dependent variable. Total maize produced (p
"Determinants of access to microcredit in Ijebu - ode local government area of Ogun state, nigeria "
(Journal of rural economics and development, 2006) Adenegan, K.O.; Yusuf, S.A.; Ibraheem, F.O.
Microcredit is an important input for enhanced productivity, employment and income generation among small and medium scale enterprises. Using stratified random sampling procedure; data were collected from 140 respondents in ljebu-Ode Local Government Area of Ogun state on the determinants of access to microcredit. The data were analysed with the aid of logistic regression analysis. The study reveals that being a male, having higher level of education, owning assets as well as generating income enhanced the log-likelihood of accessing credit. Thus, suggesting that these variables are key in improving access to microcredit in the area.
"Determinants of child labour Participation among cassava processing Households in Ogun state, nigeria "
(Journal of Economics and Rural Development, 2006) Adenegan, K.O.; Adewusi, O.A
The study examined the determinants of child labour participation among cassava processing rural households in Ogun state, Nigeria. Data were obtained using a three-state sampling procedure. The study used Logit model to analyse determinants of child labour among cassava processing households. The variables age of household head, household size, gross income from cassava processing, primary occupation of household head and poverty status of the household were found to significantly explain child labour participation among the cassava processing households. It is recommended that a policy designed to ameliorate the poverty of these rural poor must among other things recognize provision of sound education at affordable fees, encourage birth control measures would check child labour participation among cassava processing households in the study area.
Determinants of Child Mortality in Rural Nigeria
(2012) Adepoju, A.O.; Akanni, O.; Falusi, A.O.
This study examined the determinants of child mortality in rural Nigeria employing the 2008 Nigeria Demographic and Health Survey (NDHS) data. Data were analyzed using Descriptive Statistics and the Logit regression model. The result of analysis showed that the average age of the respondents at first birth is 19 years; while more than half of them had no formal education, and about three-fifths had less than 24 months birth interval. Secondary and higher education of mother, age of mother at first birth, place of delivery, type of birth, child ever breastfed, sex of child, were among the significant factors influencing child mortality in rural Nigeria. Maternal education, access to adequate health care (especially for pregnant women and children under five years) and increased awareness of benefits of breastfeeding were identified as the key factors to reducing child mortality in rural Nigeria.
Determinants of food security status of rural households living with HIV/AIDS in Southwestern Nigeria
(African Journal of Biomedical Research, 2007) Adenegan, K.O.; Adewusi, O.A.
The study assessed the determinants of food security status of households living with HIV /AIDS in Southwestern Nigeria. Eighty-five people living with HIV/AIDS were interviewed for the study, Descriptive statistics, cost of calorie measure and the Logit model were used in analyzing the data collected. The result shows that there is high prevalence of food insecurity among the households living with HIV /AIDS. The result of the Logit model also shows that gender, education, monthly food intake (Kcal), total monthly income, drug share and food share significantly influence the food security status of the households living with HIV/AIDS. To improve the food security status of households living with HIV/AIDS, it is recommended that economic policy should be directed towards the reduction of the food prices, thus reducing the food share of the household monthly expenditure

Determinants of market participation among pineapple farmers in Aiyedaade Local Government Area, Osun State, Nigeria
(Taylor & Francis, 2015) Adepoju, A. O.; Owoeye, I T.; Adeoye, I. B.
This study examined the determinants of market participation among pineapple farmers in Aiyedaade Local overnment Area of Osun State, Nigeria. Interestingly, in spite of major constraints, such as bad roads, inadequate storage facilities, and low level of government support, almost all of the farmers participated in the market. This could be sustained if market centers are established at strategic locations not too far from farms and if loans are made accessible to the farmers with low interest rates requiring simplified procedures for processing. Intervention strategies for improvement of pineapple farmers’ market participation should also be guided by farmers age, farming experience, and marital status.
Determinants of multidimensional poverty transitions among rural households in Nigeria
(IAAE, 2018) A. Adepoju, A.
Despite recent progress in poverty reduction globally, millions of people are either near or living in severe multidimensional poverty in Nigeria. This study examined multidimensional poverty transitions in rural Nigeria, employing the Alkire and Foster Measure of Multidimensional Poverty, Markov Model of Poverty Transitions and the Multinomial Logistic Regression Model for analysis. Results showed that multidimensional poverty among rural households in Nigeria is mainly chronic (46.5%) while education and assets dimensions contributed most to the incidence and severity of multidimensional poverty among the households. Educational status, household size, number of assets owned, ownership of land influenced transient poverty while marital status, household size, land ownership and number of assets owned influenced chronic poverty. The study recommends the enactment and implementation of relevant laws against marginalization of rural women in ownership of assets and intensification of efforts and incentives aimed at encouraging human capital development in the rural areas
