Unemployment and Migration in Nigeria, An Empirical Investigation
(2024-01-24) Dr. Ibeinmo Friday Cookey and Onyinye Ifeoma Ochuba
This study empirically accessed the effect of unemployment on migration in Nigeria over a period of thirty-
three years (i.e. from 1990 to 2022). Total unemployment, male unemployment, female unemployment and
urban unemployment were used as proxies of unemployment while net migration rate was used to proxy
migration. The study employed time series data which were sourced from National Bureau of Statistics
(NBS) and World Bank Development Index (WDI). Augmented Dickey-Fuller (ADF) statistic, Bounds
cointegration test and Auto regressive Distributive Lag (ARDL) approach were the techniques of data
analysis adopted. The data analysis was executed by E Views 12.0. The findings of the study revealed that
total unemployment rate, female unemployment and urban unemployment have a positive and significant
impact on net migration rate in Nigeria while male unemployment has a positive and insignificant impact on
net migration rate in Nigeria. The study concluded that unemployment is a major factor that encourages
migration in Nigeria. The study recommended that government should promote policies and initiatives that
stimulate economic growth and diversification to create more job opportunities by supporting industries
with high employment potential, such as agriculture, manufacturing, and technology.
Trade Openness, Foreign Direct Investment and Sustainable Agriculture in Africa
(ProblemyEkorozwoju/Problems of Sustainable Development, 2022-07-06) Ping Ju, Muhammad Khalid Anser, Romanus Osabohien, Onyinye Ochuba, Rolle Remi Ahuru, Junaid Ashraf
This study applied a panel data of 37 African countries in examining the impact of trade openness and foreign
direct investment on sustainable agriculture towards the attainment of the United Nation (UN) Sustainable Devel
opment Goals (SDGs), especially, SDG-2, with the aim of ending extreme hunger, achieve food security and im
prove nutrition and promote sustainable agriculture. Data for the study was sourced from the Country Policy and
Institutional Assessment (CPIA) and World Development Indicators (WDI) of the World Bank, for the period
2005 - 2019. To control for endogeneity, the study engaged the system Generalised Method of Moments (GMM).
The result shows that FDI and trade openness have significant negative impact on agricultural sustainability in
Africa. This result implies that, increase in FDI may decrease agricultural sustainability by 0.00294%, while in
crease in trade openness may lower agricultural sustainability by 0.430066 %. Therefore, the study concludes that
while trade openness is negative, policy to raise local production towards export promotion should be encouraged.
In addition, FDI should be encouraged to augment local employment and investment towards increasing output
and productivity in the Africa region.
Population Compartments and Food Security in Nigeria
(AEFUNAI JOURNAL OF ECONOMICS, FINANCE AND DEVELOPMENT STUDIES (AEFUNAIJEFDS), 0009-04-23) Onyinye Ifeoma Ochuba & Ebikabowei Biedomo Aduku
This study examines the relationship between population compartments and food
T security in Nigeria using quarterly time-series data, covering the period from 2003 to
2022. e population compartments considered were the infant population, the
working-age population, and the retired-age population. Ford security, on the other hand, was
measured by the average dietary energy adequacy and the prevalence of undernourishment.
e data was analyzed using the Non-linear Autoregressive Distributed Lag (NARDL) co
integration technique. It was found that the infant population and the retired age population
have a negative and signi cant effect on the average dietary energy adequacy proxy for food
availability and a positive and signi cant effect on the prevalence of undernourishment proxy
for food accessibility, both in the long run and short run. It was also found that both in the long
run and short run, the working-age population has a positive and signi cant effect on the
average dietary energy adequacy and a negative and signi cant effect on the prevalence of
undernourishment. Nigeria should focus on investing signi cantly in family planning and
enhancing productive health, which could cut down the fertility level. And, with more
commitment to ensuring child survival and broad implementation of universal health
coverage, the working-age population will increase relative to the other population
compartments considered in this study. Also, the working-age population and the retired-age
population should be encouraged to go into agriculture. is can be achieved through
rigorous sensitization on the relevance of agriculture and providing the enabling environment
to support the growth of agriculture in the country.
Advancing Sustainable Development Goals through Nature-based Solutions in Nigeria
(SEAHI PUBLICATIONS, 2025-04-12) Onyinye Ifeoma Ochuba
This study explores the contribution of Nature-based Solutions (NbS) to achieving Sustainable
Development Goals (SDGs), with a particular focus on SDG 2 (Zero Hunger) in Nigeria. Drawing on
data from 297 rural households collected through a structured questionnaire, the analysis utilizes the
Endogenous Switching Regression (ESR) model to examine the effects of NbS adoption on household
food security. The findings indicate that although adopting NbS alone did not yield an immediate or
statistically significant improvement in food security, longer-term use had a strong and significant
positive effect, especially among households that had adopted NbS. Key socioeconomic factors,
including education, income, farm size, and the use of climate-resilient crop varieties also had a
significant impact on food security, particularly among non-adopters. The study further reveals that
adoption decisions were not significantly influenced by observable climate-related variables, pointing
to potential unmeasured constraints such as limited institutional support or lack of information. Based
on these insights, the study recommends sustained policy interventions, enhanced farmer education,
and targeted support mechanisms to encourage long-term NbS adoption. Addressing these structural
barriers is essential for maximizing the potential of NbS in promoting sustainable agriculture,
enhancing food security, and building climate resilience in Nigeria.
A Vector Error Correction Model Analysis of the Interrelationships among Globalization, Health and Macroeconomic Outcomes in Nigeria
(Department of Economics, Federal University of Lafia, Nigeria, 2021-02-06) Francis Ilenloa Igberaese1 & Onyinye Ifeoma Ochuba2
The study ascertains the effects of interrelationships and linkages among
the three concepts of globalization, health, and macroeconomic
outcomes in Nigeria using the Vector Error Correction Model. It also
finds among others that openness, FDI, which are measures of
globalization and malaria prevalence, a direct measure of health and
economic growth has no significant effect on the exchange rate, and that
economic growth, exchange rate, measures of macroeconomic outcomes,
FDI, and malaria prevalence have no significant impact on trade
openness. It recommends among others that attempts to grow one sector
should not lose foresight of the others and that efforts to make Nigeria’s
economy benefit from globalization should focus more on stimulating
FDI than participating in trade openness. More vigorous efforts should
be put into the fight against, and treatment of malaria in the country
