Nutrient elasticities among Nigerian households differentiated by income
No full textFood calorie intake has been found to have a strong empirical linkage with both human health and productivity. In a study to determine the probable influence of price and income changes on the availability of food nutrients to Nigerian households segmented by income, demand elasticities were obtained for survey respondents and the nutritional effects of changes arising from changes in income and prices were computed using both the AIDS methodology and a technique developed by Huang. The findings show that guinea corn is the food that would have the greatest implications for the nutrient status of low income households. Millet, guinea corn and maize and rice, beans and maize respectively are the food items of note for the households whose heads earn average and high incomes. The study concludes with the implications of the findings on the different income groups and the likely applications of the methodology used to derive nutrient elasticities.Food demand, income, almost ideal demand system (AIDS), Nigeria, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety,
A COMPARATIVE ANALYSIS OF CAPTURE FISHERIES ON THE WESTERN AND EASTERN SHORES OF KAINJI LAKE BASIN, NIGERIA
No full textThe study examined fish catch on Kainji Lake in Nigeria. The data for the analysis were obtained through a sample survey of the lake basin.. A total of 252 fishermen were sampled. Multiple regression analysis was adopted in analyzing the data.. The results obtained indicate that on both shores of the lake, family labour, capital expenses, motorized operation, credit and apprentiship or training are significant factors affecting fish catch by the fish-folks.. Family labour has a negative sign. This implies over utilization of this input. Family labour input can thus be reduced without affecting the catch level. The pooled data for the two shores produced a similar result. The catch functions are characterized by decreasing returns to scale.. The Chow's test for equality of parameters of the catch functions indicated no significant difference between the shores.. It is recommended that a reduction in family labour be encouraged among the fishermen. They should be enlightened on the possibility of over-fishing the lake. The provision of credit to the fishermen is also recommended.

Technical efficiency in rice ecologies of north central Nigeria: Implications for national self-sufficiency
No full textTechnical efficiency in rice ecologies of north central Nigeria: Implications for national self-sufficiency
No full textThe quest for national self-sufficiency in rice production in Nigeria has been on for several years, with various government regimes putting different policies and programs in place in order to achieve this. A large proportion of the rice produced in Nigeria comes from the north central part, with Niger State being the second largest rice producing state in north central Nigeria. The study was carried out to examine the technical efficiency and its determinants within the rice ecologies in north central Nigeria. Through the multi-stage sampling technique, one hundred and fiftyone farmers were sampled for the study. Two mini-ecologies were identified within the lowland rice ecology in the study area, namely, River Basin Authority Catchment area (RBAC) and Non River Basin Authority Catchment area (NRBAC). Differentials in rice output were determined with the Chow test while the stochastic frontier production approach was employed to determine the technical efficiency on the individual farms. There were variations in output between the mini-ecologies, while rice output was significantly influenced by farm size, quantities of fertilisers, labour and herbicides used in rice production. Average technical efficiency measures were 70.9 and 93.6% for the identified mini-ecologies namely River Basin Authority Catchment area (RBAC) and Non River Basin Authority Catchment area (NRBAC). Variables such as extension visits and level of commercialisation had significant effects on the observed variations in technical efficiency among the rice farmers. Results indicate that there is a considerable scope for increased efficiency to meet current national rice demand.Keywords: Output differential, Stochastic frontier productio

The Processing and Preference for Locust Beans Products (Parka biglobosa ) in Lagos, Nigeria
No full textDawadawa is an important condiment that is traditionally fermented from locust beans (Parka biglobasa). This study examined its supply sources, marketing channels, and processing in terms of two products viz the sun dried and the salted products. A sensory evaluation was carried out by panelists. This is made up of lecturers, food processors, students of Hotel and Catering Management, housewives, pregnant woman and nursing mother. The hypothesis that salted product was preferred to the sun dried product was accepted. The salted product was recommended by various homes and social gatherings though the sun dried was also accepted by some group. Keywords: Processing, preference, Parkia products, Lagos Nigeri

No full textThe Persistence of Small Farms and Poverty Levels in Nigeria: An Empirical Analysis
No full textSmall farmers are one of the more disadvantaged and vulnerable groups in Nigeria. Studies have shown that majority of people living in absolute poverty can be found on small farms with half in this group undernourished. The study examined heterogeneity in circumstances and diversity in rural agriculture, the persistence of small farms, poverty and institutional development and facilities. Data for this study came from Nigerian living Standard Survey (NLSS) which covered the two periods
1994/2004. The data set consists of 9550 respondents’ but only 8264 cases were useful for this study. The index of heterogeneity at 29.1 indicated persistence of small farms in the two periods under consideration. Persistence of small farms and poverty are closely related (r = 0.674). The poverty
differential in the two surveys data revealed that poverty increased by 14.72%. Disaggregation analysis indicated that institutional development and facilities improved farm outputs, diversification
to non-farm and reduction in poverty. Access to these institutional facilities can enable the small farmers to rearticulate their livelihood activities. Policy makers need to show more commitment to develop agriculture through identifying and providing the capacity need of small farmers in order for
them to absorb and used whatever modern techniques introduced
Risk aversion and sustainable maize production in Nigeria: Some challenges and prospects for agricultural and economic development
No full textThis paper determines the degree or extent of farmer’s risk aversion that affects sustainable maize production in Northern Nigeria. Using a ridge regression analysis, a measure of risk aversion was derived for each individual farmer in a model of safety-first behaviour from a cross-sectional survey of 350 maize producers in northern Nigeria. The distribution of the degree of risk aversion shows a high skewness towards the risk averters (high risk farmers) and centered around 1.20, and standard deviation of 0.37. This distribution is then explained by a set of specific variables that characterize the farmers’ behaviour in the study area using a Tobit model. Susceptibility to risk was found to be highly premised on the socioeconomic factors (e.g. age of household head), farm specific variables (e.g. proportion of income from maize) and farmers’ attitudinal factors against risk (e.g. safety first level of probability of sale). These findings can be used to construct a framework of development programs for peasant farmers, which provide some challenging prospectsMaize, Nigeria, Risk aversion, Tobit model, Agricultural and Food Policy, Agricultural Finance, Crop Production/Industries, Farm Management, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Institutional and Behavioral Economics, International Relations/Trade, Marketing, Productivity Analysis, Research and Development/Tech Change/Emerging Technologies,
