The traditional land tenure system in Nigeria coupled with increasing population encourages land fragmentation with attendant consequences for agricultural productivity and commercialization. This study quantified the degree of land fragmentation and its consequences on arable food production. The study makes use of data from 125 farm households spread across the 12 communities in Umuahia-North Local Government Area (LGA) of Abia State, Nigeria. Using Janusezwski index, the study quantified the degree of land fragmentation. The Cobb-Douglas (CD) and the Generalized Linear Model (GLM) were used in exploring the impact of land fragmentation on arable crop productivity. The mean fragmentation index is 0.55 with a variance of 0.02. The average farm size cultivated is 2.68 hectares. Majority of the households (71 percent) clustered around the mean fragmentation index. The results of the CD and GLM show the negative impact of land fragmentation on agricultural productivity. Labour in the CD model remained the single most important factor of increasing productivity. The GLM show that cultivating farms further away from the homestead will lead to higher productivity. The study recommends cooperative farming to enable the farmers to adopt productivity improving farm technologies.
Problem statement: Nigeria runs the risk of slowing further progress toward the achievement of MDG-1 to eradicate extreme hunger and poverty; the fourth goal, to reduce child mortality since over 30% of child deaths are attributable to malnutrition and the fifth goal relating to reduction in maternal mortality. This study evaluated the manifestation of food insecurity in households in Abia State, Nigeria. Approach: Systematic sampling was adopted in selecting households from the three geopolitical zones in the state. Primary and secondary data were used in the study. Data collection involved the use of structured questionnaires. Food intake, height and weight measures of children were taken Data analysis in involved the use of qualitative and quantitative methods. Results: Domestic food production is increasing but demand remained above production. The shortfall along with food import is on the increase. The composite consumer price index for food has continued to rise over the years. Logistic results show that income significantly reduced exposure to food insecurity while household size was an important determinant of food security. Children were more exposed to the incidence of growth retardation and stunting with increasing household size. Birth order increases the incidence of stunting. As more children come into the family there is increasing marginalization of the subsequent ones. Conclusion: Food insecurity is a developmental challenge in Nigeria. The country is characterized by high food imports and declining productivity of agriculture. Malnutrition is widespread especially among children in rural Nigeria. The study recommends family planning education to stern the over bloated population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
