Climate change poses mounting risks to agricultural development and rural livelihoods in Nigeria. This study investigates the impacts of climate change on agricultural sector employment in Nigeria. Agriculture provides income and sustenance for much of Nigeria’s rural population. However, smallholder rain-fed farming predominates, with minimal resilience to climate shifts. Historical data reveal rising temperatures and declining, erratic rainfall across Nigeria’s agro-ecological zones since the 1970s. Crop modeling predicts further climate changes will reduce yields of key staple crops. This threatens the viability of smallholder agriculture and risks widespread job losses. The study adopts a nonlinear autoregressive distributed lag (NARDL) modeling approach to evaluate climate change effects on agricultural sector employment in Nigeria from 1990 to 2020. Findings reveal reduced rainfall initially raises employment, as farming requires more labor in dry conditions. However, protracted droughts significantly reduce agricultural jobs. Increased temperatures consistently lower farm employment through reduced yields and incomes. Based on these findings, the study recommends that adaptive strategies are urgently needed to build resilience, promote climate-smart agriculture, and safeguard rural livelihoods.

Increasing environmental degradation and its impact on long-term economic prosperity have become major global concerns, particularly in developing economies like Nigeria. Environmental quality is crucial for Sustainable Development (SD), affecting economic growth, resource availability, and societal well-being. However, balancing economic growth and environmental preservation remains a challenge for policymakers. Therefore, this study uses an Autoregressive Distributed Lag (ARDL) estimation approach to examine the relationship between environmental quality and SD in Nigeria using quarterly data from 2000 to 2021. The research examines the impacts of CO₂ emissions, forest area, Natural Resource Depletion (NRD), capital, and labor on SD from both short- and long-term perspectives. The findings demonstrate that CO₂ emissions negatively affect SD, emphasizing the importance of strong environmental legislation. In contrast, forest areas have a beneficial impact on SD, emphasizing the necessity of environmental preservation. Lagged and contemporary NRDs show trade-offs between resource use and long-term prosperity. Capital emerges as a key engine of SD. However, this study finds that factors like labor lack statistical significance in explaining variations in SD. These insights provide valuable guidance for policymakers aiming to balance economic growth with environmental sustainability. The study recommends the implementation of stringent environmental policies to curb CO₂ emissions and emphasizes the need for responsible resource management practices to mitigate the adverse effects of NRD.

This paper specifically explores the impacts of the Belt and Road Initiative (BRI) infrastructure diplomacy in Nigeria, with a particular focus on two crucial sectors: ports and railways. It analyzes the challenges and conditions that have led to delays and abandonment of previous projects awarded to China in the past decades. Through the lens of complex interdependency theory, this paper discusses the push and pull factors that motivated the execution of BRI projects in Nigeria and how they mutually benefit the actors involved. Furthermore, it utilizes primary and secondary data gathered through Key Informant Interviews and documented sources. On the strength of the findings, this paper concludes that the BRI, unlike past Chinese projects in Nigeria, has significantly enhanced the development of infrastructure by modernizing the Nigerian railway facilities and constructing the first deep seaport in the country.

Among female subjects of reproductive age, polycystic ovarian syndrome (PCOS) is a common endocrine disorder that may be linked to a number of health risks for cardiovascular diseases (CVDs). The study aims to determine some CVD risk variables and how they relate to body mass index (BMI) in female subjects with PCOS. Fifty healthy women without PCOS (controls) and 90 women with PCOS between the ages of 18 and 45 were enrolled in the study. Standard methods were used to evaluate the serum sex hormones, lipid profile, troponin-I, highly sensitive C-reactive protein (hs-CRP), fasting blood glucose, and atherogenic indices. Compared to controls, the mean age of women with PCOS was substantially lower ($p<0.001$). The mean values of BMI, waist circumference, and hip were not significantly different from one another. While the cardiometabolic variables were higher in women with PCOS than in healthy subjects, no significant difference between obese/overweight and nonobese women with PCOS in terms of mean BMI, fasting blood glucose, insulin, atherogenic index of plasma (AIP), troponin-I, hs-CRP, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol were observed. In PCOS-affected women, AIP ($r=0.712$, $p<0.001$), lipid accumulation product (LAP) ($r=0.764$, $p<0.001$), and hs-CRP ($r=0.666$, $p<0.001$) all showed positive correlations with BMI. Regardless of BMI status, there was an independent correlation between cardiovascular risk factors (CVRFs) and PCOS. This implies that regardless of a woman’s BMI, PCOS may increase her risk of CVD. Treatment combined with lifestyle modifications may be useful in lowering the risk of CVD in PCOS-afflicted Nigerian women. The finding suggests that PCOS itself, independent of weight, may increase the risk of heart disease. Nigerian women with PCOS are at increased risk of CVD, regardless of their BMI, and early detection, prevention, and treatment of CVRFs in women with PCOS is desirable.

This article reviews the use of the Interactive Voice Response (IVR) mechanism in delivering enterprise education to the Micro, Small and Medium Enterprises (MSMEs) sector in Nigeria. Using desk research and review of system performance report, the suitability of the IVR mechanism as an alternative approach towards ensuring inclusiveness in entrepreneurship education is highlighted. The review revealed that deploying learning systems that take into considerations geographical locations without internet infrastructure and also socio-economic factors of intending and existing entrepreneurs for enterprise education is crucial and equally promising. The challenges and opportunities of online and continuing education during the COVID-19 pandemic are summarized. There is the need for further exploration of IVR interventions to make them more effective and policy interventions on affordable online teaching and learning platforms accessible to persons of varied economic divide.
