PurposeThe study examined policy improvement and cassava attractiveness. The purpose was to determine the optimum rewards using three strategies: selling of farm produce to harvesters, making wholesale of harvested outputs and retailing harvested outputs.Design/methodology/approachThree hundred and sixty (360) cassava farmers were surveyed in three local government areas in Edo South senatorial district of Nigeria. From their responses, probabilities were assigned to rewards for each strategy from each of the locations. Subsequently, dynamic programming was employed in data analysis. Specifically, Howard policy improvement technique was used to forecast expected rewards to cassava farmers in the three local government areas using the three strategies.FindingsCassava farmers in Edo South senatorial district of Edo state, Nigeria, can maximize their earnings from cassava by retailing at the local markets in Oredo and Egor local government areas and by making wholesales at Ikpoba Okha local government area. Using this policy, they will realize approximately N2360 per basin and approximately N33040 per plot of 100 × 100 ft. This will translate to N143724 per acre (4.35 plots of 100 ft2).Research limitations/implicationsAvailability of storage facilities as well as technical constraints to cassava production.Social implicationsProvision of jobs to the unemployed, thereby reducing the level of unemployment in the country.Originality/valueSuggestion of the sales strategy that will yield optimum returns to cassava farmers, using policy iteration technique, and the projected estimates of the likely turnover when the strategy is adopted. This is a point of departure from previous studies. Thus, the study used operations research methodology to model solutions, through involvement in agriculture, to Nigeria's economic/financial problems, thus making it unique. In broad terms the study demonstrates that investment in agriculture will help to reduce unemployment and enhance the country's national income.

Cassava attractiveness in Nigeria: a policy improvement approach

“…This study adopts de Waal and Whiteside's (2003) “new variant farming” theory as its framework. de Waal and Whiteside (2003) highlight four factors consistent with Inegbedion and Aghedo (2018) that characterize those affected by the HIV/AIDS epidemic to be: (1) “Household labour shortages; (2) Loss of assets and skills due to adult mortality; (3) The burden of care for sick adults and orphans and (4) The vicious interactions between Malnutrition, HIV infection and progression.” The combined impact of the highlighted factors may undermine the effectiveness of the strategies available to prevent or cope with the threat of famine, or these coping strategies may be rendered inapplicable or dangerous to forestall food insecurity in the short-run. Food insecurity may then degenerate into famine on the long-run and households affected by AIDS face outright starvation.…”

COVID-19 lockdown: implication for food security

JADEE

PurposeThe purpose of the paper is to sought to know the implication of COVID-19 lockdown for food security in NigeriaDesign/methodology/approachThe study examined implication of COVID-19 lockdown for food security. The cross sectional survey research design was employed. Information was elicited from respondents through the social medium (Facebook). The question response format of the instrument was of the five-point Likert scale type. Research data were analysed using one sample t-test and least squares (regression).FindingsThe results show that COVID-19 lockdown can significantly constrain farm labour, transportation and security, while food security can be threatened by insufficient labour, transportation, farmers' morale and farm coordinationResearch limitations/implicationsA major limitation was the restriction to only online data collection method owing to the researcher's inability to administer the instrument physically as a result of the lockdown. This had an implication on randomisation.Social implicationsLong stay of people at home and away from farm activities will threaten food security on the long run and thus, precipitate social vices due to the attendant hunger and deprivationOriginality/valueIn empirical examination of the impact of COVID-19 pandemic lockdown on food security, thereby providing statistical evidence that will be useful in the sensitisation of stakeholders on the need to thread on the part of caution to avoid the possible consequences of restricting farmers' operations through the COVID-19 lockdown.

“…The type of school (public or private) and classes of students were measured on a categorical scale. Measurement of realised teaching time and time utilisation are both ratio, consistent with Inegbedion and Aghedo (2018) while the measurement of type of school is nominal.…”

This study investigated the extent to which teachers' time utilisation influences students' enrolment in certificate examination and compared the realized teaching time by teachers in public and private secondary schools in Benin, Nigeria to draw the attention of school leadership to the importance of teachers' time utilisation to the attainment of educational goals. The survey design was employed to elicit data from three hundred and sixty randomly selected senior secondary school students from five public and five private senior schools. Questionnaire served as the data collection instrument and the data were subsequently analysed using Kolmogorov Smirnov test, Mann Whitney U test and Kruskal Wallis test. Results indicate that realised teaching time and time utilisation by the teachers in public secondary schools is significantly lower than what obtains in private secondary schools and significantly lower than the expected teaching time. The realised teaching time and time utilisation also varied significantly within the public and private secondary schools and between classes in public and private secondary schools. Lastly, class sizes were significantly large in uencthe public schools but generally small in the certificate classes, thus implying that teachers' time utilization has a significant impact on students' enrolment. The need for school leaders and administrators to ensure increased teachers' time utilisation for enhanced enrolment in certificate examinations was suggested, among others.
