    THE NEXUS BETWEEN DEBT SERVICING AND FOREIGN EXCHANGE RATE UNIFICATION IN NIGERIA
    (Malete Journal of Management and Social Sciences, 2024-12-11) Taofeekat Temitope Nofiu; Nofiu Babatunde Nofiu
    Public debt, which has escalated to approximately N38.005 trillion by the first quarter of 2024, has become a critical concern for Nigeria's economic sustainability. The country's debt service-to-revenue ratio has reached 183%, indicating a severe fiscal imbalance. Hence, this study examined the relationship between debt servicing and foreign exchange rate unification in Nigeria from 1995 to 2023. Using an Autoregressive Distributed Lag (ARDL) model, the research investigated the effect of exchange rate unification, inflation, GDP growth, and oil prices on Nigeria's debt service-to-revenue ratio. The findings reveal that exchange rate unification has a significant negative effect on the debt service burden, suggesting potential benefits of a unified exchange rate policy. Inflation rates and lagged exchange rates also negatively impact debt servicing, while oil prices show mixed effects. Based on these findings, the study recommends that policymakers continue pursuing exchange rate unification while implementing careful inflation management strategies. Also, the research suggests focusing on economic diversification to reduce oil dependence and improving fiscal discipline to better manage persistent debt servicing commitments.

    Energy-Growth Nexus: A Systematic Review of Empirical Evidence and Policy Implications
    (African Journal of Environmental Sciences & Renewable Energy, 2025-04-16) Ololade Mistura Aromasodun; Musa Ilias Biala; Abdul Muftah Shitu
    The relationships between energy consumption and economic growth have been extensively studied in the economic and energy literature, yet empirical findings remain inconclusive. This systematic review examines the existing theoretical and empirical research on the energy-growth nexus, analyzing studies from developed and developing economies. The review explores four primary hypotheses: the growth hypothesis (energy consumption drives economic expansion), the conservation hypothesis (economic growth influences energy demand), the feedback hypothesis (a bidirectional relationship), and the neutrality hypothesis (no causal relationship). Findings indicate that the energy-growth relationship varies across countries depending on factors such as income levels, energy mix, and methodological approaches. Developed economies tend to exhibit a shift toward energy efficiency and the conservation hypothesis, while developing economies largely support the growth hypothesis, highlighting their dependency on energy for industrialization. The increasing role of renewable energy in sustaining economic growth is also examined, with evidence suggesting that while renewable investments support long-term economic sustainability, short-term transition challenges exist. The review underscores the need for balanced energy policies, renewable energy investment, and technological innovations to ensure sustainable economic growth while minimizing environmental impact. Future research should focus on regional-specific dynamics, the role of institutional factors, and the implications of climate policies on the energy-growth relationship.

    Impact of Environmental Courses on Pro-Environmental Behaviours of University Students: Evidence from Kwara State University, Nigeria
    (African Journal of Environmental Sciences and Renewable Energy, 2025-04-16) Aromasodun, Ololade Mistura
    People who take environmental courses are widely regarded as exhibiting more proenvironmental behaviours (PEBs) than those who do not. However, little or no research has established this. This study, therefore, examines whether and how taking an environmental course determines the adoption of PEBs. This study analyses the extent to which students who take environmental courses engage in PEBs, using Kwara State University as a case study. Drawing on framework of Knowledge-Attitude-Behaviour theory, the study investigates the relationship between taking an environmental course and adoption of PEBs. We conducted a survey 416 students to examine this relationship. A stratified random sampling method was employed to select students from academic departments offering environmental courses and those that do not. Data were collected through a structured questionnaire and analyzed using descriptive statistics, classical linear regression model and multivariate logit regression model. This study found that exposure to environmental courses significantly influenced PEBs. Students who took environmental courses were more likely to engage in activities such as energy conservation, reusing, proper waste disposal, and recycling compared to their counterparts who did not. The implications of these findings for policy and practice in higher education are discussed, offering insights into how educational institutions can contribute to achieving global environmental sustainability goals.

    Does the relative size of agricultural exports matter for sustainable development? Evidence from Sub-Sahara Africa
    (Elsevier, 2025-01-06) Taofeekat Temitope Nofiu; Rashidat Sumbola Akande; Hauwah KK Abdulkareem; Sodiq Olaiwola Jimoh
    This study investigates the effect of the relative size of agricultural exports on sustainable development across 46 sub-Saharan African countries between 1999 and 2020. Using data on adjusted net savings and sustainable development indices as proxies for sustainable development, the empirical analysis applies the Driscoll-Kraay standard error method which accounts for cross-sectional dependence. The results indicate that the relative size of agricultural exports has a positive effect on sustainable development while agricultural non-export pro duction is found to contribute more to sustainable development than agricultural exports. Given agriculture’s dominance and the agro-based export potential for these economies, the study recommends pro-agricultural export policies aimed at expanding agricultural exports over non-agricultural exports if the choice is between exporting agricultural commodities and exporting non-agricultural commodities. However, the import substi tution strategy should be prioritized over the agricultural export promotion strategy when choosing between exporting agricultural commodities and producing for domestic consumption for higher sustainable outcomes.

    Informal Employment and Inequality: Implications for Migration in Sub-Saharan Africa
    (UTS ePRESS, 2025-03-31) Rashidat Akande; Hauwah AbdulKareem; Sodiq Jimoh; Taofeekat Temitope Nofiu
    A sizable level of informal employment, often stemming from social disparities and limited economic opportunities, can have great implications for migration in Sub-Sahara Africa. Similarly, inequality, particularly unequal access to economic resources in the formal sector, can serve as a key driver for migration as people seek better opportunities. Therefore, this study investigates the individual impact of the size of informal employment and inequality on migration within the region by examining the individual effects of informal employment and inequality as well as their interactive effect on migration. Utilizing System GMM method of analysis, the study examined the data from 43 Sub Saharan African countries from 2009 to 2022. The findings suggest that both informal employment and inequality positively influence migration flows in the region. Additionally, the analysis shows that the interaction between informal employment and inequality exerts a negative effect on migration flow
