Research paper thumbnail of The pattern of healthy diets and zero hunger among households in South-West Nigeria: application of linear approximation to quadratic almost ideal demand system

In Nigeria, the prevalence of malnutrition and food insecurity is high, with a significant burden in the South-West region. Despite several interventions aimed at promoting healthy diets and reducing food insecurity, little is known about the pattern of healthy diets and zero hunger among households, as well as the budget shares on the food items driving these outcomes. Therefore, this study analyzes the pattern of healthy diets and zero hunger among households in South-West Nigeria, using the primary data elicited from 600 rice-consuming households, drawn through a multistage random sampling technique. Descriptive statistics and Linear Approximation to Quadratic Almost Ideal Demand System (LA-QUAIDS) model were used to analyze the dataset. The estimated LA-QUAIDS model was helpful to decipher the relationships that m...

Therefore, this study examined the vulnerability of agrarian households to livelihood shocks using a sample size of 368 farmers selected from Oyo State, Nigeria, through a multistage sampling technique, and from whom relevant data were elicited. This study applied the livelihood vulnerability index approach, and composite score technique to decipher the vulnerability space of the respondents, and for the ordinal categorization of the respondents into different vulnerability categories, respectively. The study also used proportional odds model to investigate the determinants of livelihood vulnerability from the perspective of adaptive capacity vis-à-vis the livelihood capital assets of the farmers. Findings from the study indicated that...

Research paper thumbnail of Sustainable Food Systems and Farmers' Welfare Status Distribution in Oyo State, Nigeria: Building Buffers Against Shocks and Stressors Through Resilience Pillars

Respondents were drawn from the study area through the multistage random sampling technique; while the data obtained from 363 sampled respondents were analyzed and described through the use of descriptive statistics (frequency distribution, percentages, and cross tabulation technique). The resilience tool of the Food and Agriculture Organization of the United Nations (UN-FAO) was adopted to measure the resilience pillars through their corresponding components/indicators. Similarly, a quantile regression econometric model was used to estimate the effect of the resilience pillars vis-à-vis the indicators on welfare distribution in the study area. The results indicated that the majority of the respondents fall within the low quintiles of households' welfare, while women were found to be dispropor...

They are most vulnerable to this dwindling situations; this dirge persists till today. There is growing evidence that social capital is an additional input in the household's production function and as such, element for sustainable development due to the roles it plays in managing risks, shocks, and opportunities for increased food crop production and improving household welfare. It has been observed that not all social capital leads to growth or development. Some social capital may be beneficial while some may be deleterious depending on the motives behind its formation. Data collected from 233 respondents through multistage sampling was analyzed through composite score analysis, probit and ordered probit regression models. Findings revealed that more than half (66....
