Publication Open Access Impact of Economic Globalisation on Agricultural Value-Added: The African Region Experience(Springer, 2026-01-27) Wisenthige, K; Jayathilaka, RGlobalisation has been a critical driver of economic growth in many nations. However, the agricultural sector has yet to realise its full potential in terms of agricultural value-added and the distribution of benefits to primary producers within value chains. Notably, the African region possesses a high potential for agricultural value-addition compared to other regions. This research examines the impact of economic globalisation on agricultural value-added within the African context. Using advanced statistical techniques, including panel data regression and multiple linear regression, the study assesses the influence of globalisation on agricultural value-added across 26 African countries from 2000 to 2021. The findings indicate that, while certain countries have benefitted significantly from economic globalisation, enhancing their agricultural value, the majority still require a greater focus on optimising agricultural value addition. Senegal exhibited the most pronounced impact on agricultural value addition, whereas Burkina Faso, Morocco, South Africa, Tunisia, and Uganda showed negligible impacts. Policies aimed at optimising fertiliser inputs, advancing technology, developing the technical knowledge, skills, and attitudes of the agricultural labour force, facilitating foreign market access for raw materials, and promoting sustainable agricultural practices could help enhance value addition and support the overall economic development of the African region. This research contributes to the knowledge-based economy by providing empirical insights into the factors driving agricultural value-added, underscoring the role of knowledge creation, diffusion, and application in boosting agricultural productivity and economic growth in the African region.Publication Open Access Unravelling the impact of fossil fuel consumption and urbanisation on black carbon emissions in Africa(Springer Nature, 2026-05-12) Pinnawala, P; Samarasinghe, B; Samarasingha, N; Wijethunga, P; Dharmapriya, N; Yapa, SBlack carbon (BC) is a leading short-lived climate pollutant (SLCP) with profound health and climate impacts. This research investigates the impact of fossil fuel energy consumption (FFEC) and Urbanisation (URB) on black carbon emissions (BCE) in 34 African countries over the period 2005–2022. Data were analysed using a panel regression with fixed effects (x2 = 97.26, p < 0.001) to estimate the effects of each variable. Cross-country heterogeneity is further examined using country-level multiple linear regression (MLR) models. The fixed-effects model with clustered standard errors finds that fossil fuel energy consumption is weakly and negatively associated with Black carbon emissions. The average effect of countries in URB is not considered strong. In contrast, URB shows a positive and significant association with BCE in Eritrea, Ghana, Madagascar, Mauritius, Morocco, Niger, and Zimbabwewhile FFEC shows a positive and significant impact on BCE in Ghana and Zimbabwe. These results indicate that poorly planned urban sprawl overlaps with energy poverty, as it dramatically increases BCE. Policymakers should focus more on implementing cleaner cooking facilities, reliable low-carbon electricity generation, and eco-friendly transportation modes to achieve BCE neutrality.Publication Embargo Unveiling the Economic Determinants of Child Labour in Africa: A Comprehensive Study of 37 Countries(Springer Science and Business Media, 2025-03-10) Muthugala, H; Magammana, T; Bandara, A; Perera, A; Jayathilaka, RThis study investigates the impact of unemployment, household income and expenditure, globalisation, and foreign direct investment (FDI) on child labour across 37 African countries from 2010 to 2021, employing panel and multiple linear regression models. The findings reveal diverse impacts: rising unemployment significantly increased child labour in countries like Ethiopia and Niger, while in Cameroon and Kenya, it had a negative effect. Globalisation’s influence varied, strongly reducing child labour in Ghana but exacerbating it in Burundi. Household income and expenditure generally reduced child labour, particularly in Ethiopia and Zambia. The effect of FDI was also mixed, decreasing child labour in Madagascar but increasing it in countries with weaker governance. These insights underscore the necessity for tailored, country-specific policies that consider local economic conditions and governance quality. Future efforts to combat child labour must focus on developing sustainable solutions that address these complex dynamics.Publication Open Access Globalisation and growth nexus: Evidence from Africa through Granger Causality and Wavelet Coherence(Elsevier, 2025-06-08) Wijesuriya, P.; Athalage, D; Rathnayake, D; Sandanayaka, I; Jayathilaka, RThis study analyses the causal relationship between economic growth with globalisation and its economic, social and political facets in 33 African nations, for 51 years from 1971 to 2021. On an empirical perspective, the Granger Causality Test is utilised in the cross-country analysis, with the Wavelet Coherence methodology being conducted to comprehend the growth-globalisation nexus for the African region. Conceptually, the study is based on the Endogenous Growth and Dependency theories in identifying how globalisation drives growth in Africa. Unidirectional causal flows between globalisation and growth have been revealed for Benin, Burundi, Cameroon, Côte d’Ivoire, Kenya, Mauritania, Seychelles, Sierra Leone, and Uganda. Bidirectional causal flows between globalisation and growth have been revealed for Eswatini, Egypt and Rwanda. The study also suggests the strengthening of economic, social and political integrations, leveraging natural resources for sustainable growth, and cultivating resilience against external shocks while extending targeted support for low-performing nations in the region as strategies to improve the globalisation-growth nexus in the region. The study contributes to the existing literature by providing a holistic assessment of the growth-globalisation dynamics in Africa and its regional nations, extending over five decades, and using a dual-method approach.Publication Open Access Unmasking climate vulnerability in Africa: the role of CO2 and CH4 emissions on rising temperatures and sea levels(www.nature.com, 2025-05-02) Gunaratne, T.; Liyanage, S.; Punchihewa, C; Badurdeen, S; Jayathilaka, RClimate change influenced by anthropogenic emissions is a global occurrence affecting the Mean Surface Temperature (MST) and Mean Sea Level (MSL) patterns. The African continent contributes to the lowest Greenhouse Gas (GHG) emissions globally. However, GHG emissions, particularly Carbon Dioxide (CO2) and Methane (CH4) emission patterns, show a continuous increase in the African region, reflecting the importance of practising economic growth in the continent with sustainable environmental policies to meet future global climate targets. Given Africa’s increasing emissions and the continent’s vulnerability to climate change, this study contributes to the existing literature by assessing the continental and country-wise impact of CO2 and CH4 emissions on MST and the resulting impact on MSL through Fixed Effect (FE) panel estimation and Simple Linear Regression (SLR). The research employs data from 1993 to 2020 for fifty-four African countries. The study’s main findings show that CO2 and CH4 positively impact MST at a 1% significance level, and MST positively impacts MSL at a 5% significance level. This study focuses on continent-specific and country-specific emissions and their impacts and proposes policy measures to mitigate the emissions in the African continent.Publication Open Access Unveiling the Economic Determinants of Child Labour in Africa: A Comprehensive Study of 37 Countries(Springer Nature, 2025-02-28) Muthugala, H; Magammana, T; Bandara, A; Perera, A; Jayathilaka, RThis study investigates the impact of unemployment, household income and expenditure, globalisation, and foreign direct investment (FDI) on child labour across 37 African countries from 2010 to 2021, employing panel and multiple linear regression models.
