    Welfare Effects of Policy-induced Rising Food Prices on Farm Households in Nigeria
    (AgEcon search, 2014) Shittu, A. M.; Obayelu, O.A.; Salman, K. K.
    Against the background that domestic policies in Nigeria have been linked to an endemic - high, volatile and rising food prices in the country, this paper empirically examined the transmission of key monetary policy variables to domestic food prices in Nigeria. Furthermore, the study employed estimates of policy induced price changes from estimated cointegrating relations between commodity prices and policy variables, and demand elasticities from a system of household demand equations to estimate the associated compensating variation as a measure of the welfare impacts on farm households. The study found that government management of exchange rates and money supplies as well as withdrawal of subsidies from petroleum products have been the main driver of rising food prices in the country. While an average farmer was found to have benefited from the policy induced rising food prices with the mean compensated variation of -3.3% of the household budget, most of the farm households ended up being losers. The gainers were mostly owners of the relatively few large farms (-36.9%) including the commercial livestock farms (-38.9%), rice farm (-35.0%), and fish farms (-27.8%). Smallholders, which constituted about three-quarter of the farm households, lost on the average, about 8.1% of their purchasing power to the rising food prices, with female headed households also loosing 6.6% of their purchasing power.

    Determinants of on-farm cassava biodiversity in Ogun State, Nigeria
    (Taylor & Francis, 2015) Obayelu, O.A.; Akintundea, O.O.; Obayelu, A.E.
    Global food security depends on agro-biodiversity. However, an enormous quantum of genetic diversity of agricultural crops has been lost over the last century, and this implies vulnerability, increased economic risks, reduced food security, loss of resources for future adaptation as well as reduced and unsustainable agricultural growth opportunities. This study examined the determinants of on-farm cassava biodiversity in Ogun State, Nigeria. We profiled cassava biodiversity indices of farmers in the state according to Margalef, Shannon and Simpson diversity indices, and identified factors influencing cassava biodiversity. Data collected from 160 cassava farming households using a multistage sampling procedure were analyzed with descriptive statistics, Poisson regression and Tobit regression models. Farmers’ experience had a positive relationship with their on-farm cassava biodiversity (p < 0.1). The arable land size controlled by the farmer was positively related to Margalef (p < 0.01), Shannon (p < 0.05) and Simpson (p < 0.01) indices. However, the land squared variable was negatively related to Margalef (p < 0.01), Shannon (p < 0.05) and Simpson (p < 0.01) indices. It was recommended that appropriate agricultural land reforms should be incorporated into the agricultural transformation agenda as a key to fostering on-farm cassava biodiversity.

    Effect of Distance on Utilization of Health Care Services in Rural Kogi State, Nigeria
    (RoutlegeTaylor & Francis Group, 2011) Awoyemi, T.T.; Obayelu, O.A.; Opaluwa, H.I.
    Adequate and equitable distribution of health care facilities in rural areas is critical to human capital development. The study determined factors influencing utilization of health facilities in rural Kogi state, Nigeria. The data for the study were collected from 160 rural households and 60 health care providers from randomly selected rural areas from the four agricultural zones in Kogi state. The indices of accessibility reveal that there is unequal access to modern health facilities in the study area. The multinomial logit was used to analyze the factors influencing the utilization of health facilities in the study area. The result reveals that household size, distance and total cost of seeking health care affect the utilization of government and private hospitals while total cost of seeking health care and the quality of access route affect the use of traditional care. The policy implication arising from this study suggests that distance to improved health facilities and the total cost of seeking health care need to be reduced to enhance accessibility to improved health services by various socio-economic groups in the area.
