Publication Embargo Accessibility and usability of virtual learning platforms: Lived experiences of visually impaired undergraduates in Sri Lanka(Elsevier Ltd, 2026-03-12) Rajapakshe, W; Wickramaarachchi, C; Alwis, M.K. S.S; Amarasinghe, A.A. M.L; Jayasekara, P.N; Jayasekara, P.TThis study explores the accessibility and usability of virtual learning platforms of visually impaired undergraduate students in Sri Lanka, focusing on their lived experiences, use of assistive technologies, and institutional support mechanisms. As online learning becomes increasingly prevalent, accessibility and inclusive challenges persist, particularly in developing countries with limited infrastructure and institutional support. Despite the availability of assistive technologies, visually impaired learners frequently encounter barriers, including poorly designed platforms, limited usability of screen readers, and inadequate institutional guidance. Addressing a critical research gap, this study investigates how visually impaired undergraduates experience and navigates virtual learning environments to identify accessibility barriers, enabling practices, and context-specific strategies for inclusive digital learning. Using a qualitative approach, semi-structured interviews were conducted with fifteen visually impaired university students across Sri Lanka. Thematic analysis revealed five core themes: barriers and challenges to effective virtual learning, preferred virtual platforms, accessibility features and tools, facilitators of learning success, and strategies to optimise the learning environment. These findings illuminate how systemic inequalities, infrastructural limitations, and institutional neglect collectively constrain the digital learning experience for visually impaired students, while also highlighting enabling practices that foster access and inclusion. The study's originality lies in foregrounding student-led insights in a developing country context and integrating practical, context-specific recommendations for platform developers, educators, and policymakers. By centering the voices of visually impaired learners, this research contributes unique and actionable knowledge to the field of inclusive digital education.Publication Open Access Achieving zero hunger: A global policy lens on food security drivers and income group disparities(Elsevier B.V., 2026-03) Pulle, N; Sampath, P; Perera, S; Wijayaweera, D; Jayathilaka, RMany countries struggle to meet their daily dietary requirements despite numerous attempts to address the existing demand. Consequently, this study collectively analyses the impact of urbanisation, renewable energy, greenhouse gas emissions, population growth, gross domestic product per capita and agricultural land on food production relying on Sen's Entitlement Theory, thus providing insights to resolve the long-standing issue of food insecurity, and support the achievement of the Sustainable Development Goals. The study utilises a stepwise panel ordered Probit model on 146 countries, for the years 1993 to 2023. It further categorises the food production index into three categories of food security as; low, moderate and high, thereby enabling discussion of the likelihood of a country falling into one of the aforementioned food security categories over the years. Urbanisation, agricultural land, and the dummy variables introduced to represent the income groups have been identified to have a significant and favourable relationship with the food production index. In contrast, the greenhouse gas emissions and renewable energy variables have a significantly inverse impact on the food production index. This makes a unique contribution to the existing body of literature, especially by comparing odds over the years, across different food secure categories, countries, and their specific income levels. This study enables policymakers to gain a comprehensive historical perspective on each case. This study further promotes the Sustainable Development Goals, highlighting areas where these goals have been negatively impacted. Additionally, the study discusses optimised investment allocations, agricultural research and development, agricultural technology, climate resilient farming, and sustainable urbanisation planning as solutions for extreme cases.Publication Open Access Achieving zero hunger: A global policy lens on food security drivers and income group disparities(Elsevier B.V., 2026-01-19) Pulle, N; Sampath, P; Perera, S; Wijayaweera, D; Jayathilaka, RMany countries struggle to meet their daily dietary requirements despite numerous attempts to address the existing demand.

This study examines how UI/UX skills (UIUX), soft skills (SS), and technical skills (TS) influence the employability (EP) of IT undergraduates in Sri Lanka, addressing a notable gap in existing literature that often examines these competencies in isolation and predominantly within Western contexts. The current study offers a detailed examination of employability determinants in Sri Lanka’s IT sector by incorporating gender as a moderating factor and investigating the mediating roles of self-efficacy (SE) and proficiency levels (LP). The collection of data involved 345 IT undergraduates participating in structured surveys, which were subsequently analyzed using partial least squares structural equation modelling (PLS-SEM). The results demonstrate that gender significantly affects the relationship between soft skills and technical skills with employability, underscoring differences in the assessment of these competencies among different genders. Moreover, the degree of proficiency influences the connection between technical skills and employability, yet it does not play a significant mediating role in the relationship between soft skills and UI/UX employability. Self-efficacy has proven to be a significant mediator across various skill categories UI/UX, soft, and technical highlighting its essential function in converting competencies into career success. This work seeks to add to existing knowledge by tackling the main significant gap of examining the combined effect of UI/UX, soft, and technical skills on employability. This study contributes to the theoretical understanding of employability by presenting an integrated model that elucidates the complex interactions among skills, mediators, and gender within the Sri Lankan IT sector. The results provide actionable insights for educators, policymakers, and industry leaders, advocating for curriculum alignment with industry needs and the promotion of self-efficacy through mentorship and experiential learning.Publication Open Access Beyond compensation: effect of employee benefits on job motivation, performance, and turnover intention(Cogent OA, 2026) Peemanee, J; Weerarathna, R; Issarapaibool, A; Boonlua, S; Rathnayake, NThis study investigates the influence of employee benefits on motivation, performance, and turnover intention within contemporary workplaces that increasingly emphasize employee well-being. Addressing a key gap in the literature, it employs Structural Equation Modeling (SEM) and analyzes data from 387 Generation Y and Generation Z employees in Small and Medium Enterprises (SMEs) in Thailand. The analysis examines how diverse benefit types influence employees’ motivation, performance, and decisions to remain with their organizations. The findings reveal a direct and positive link between employee benefits, enhanced motivation, and improved performance, which together significantly reduce turnover intention. Specifically, attraction and retention strategies, organizational support mechanisms, and a growth-oriented, well-being-focused environment emerged as critical factors in motivating employees and elevating their performance. Overall, the study demonstrates that strategically designed employee benefit packages—aligned with employee needs and workplace realities—foster engagement, productivity, and loyalty. This study contributes valuable insights for organizational leaders seeking to refine benefit systems and extends the academic understanding of the strategic importance of non-monetary benefits in promoting employee satisfaction and retention.Publication Embargo Bridging tradition and innovation: exploring vegetable harvest loss reduction strategies in Sri Lanka(Emerald Publishing, 2026-01-15) Jayasuriya, N; Yapa, C.G; Rathnayake, T.A; Dilhara, A; Rathnayake, I.D; Mathangadeera, RPurpose – This study aims to address a significant gap in the literature regarding vegetable harvest loss reduction methods, exploring both traditional and modern perspectives in Sri Lanka, which is largely driven by an agricultural economy. This study explores the diverse strategies employed and how they are going to be integrated by Sri Lankan vegetable farmers, highlighting both traditional and modern pre- and post-harvest practices aimed at improving productivity, sustainability and resilience in agricultural systems. Design/methodology/approach – The study was conducted across key agricultural districts in Sri Lanka, with data collected through semi-structured interviews with vegetable farmers using the snowball sampling method. Thematic analysis was employed to identify patterns and themes in the data. Findings – The findings emphasize the importance of traditional methods, including cultural practices such as cultivating at auspicious times, established pest control and irrigation techniques. These are complemented by advanced agricultural innovations, modern harvest protection methods and improved packing and transportation techniques. This integrated approach showcases farmers' adaptability in reducing vegetable losses despite the challenges they face. Originality/value – Post- and pre-harvest loss reduction in Asian countries can be considered an understudied area. Furthermore, the focus on traditional methods is rare in the field. Therefore, this study provides a clear understanding of traditional and modern methods that are suitable for farmers in developing countries.Publication Open Access Dynamic linkages between chicken meat production, consumption, income and trade: Evidence from Wavelet coherence and Granger causality in Asia(Elsevier Inc., 2026) Silva, Y; Susan, H; Perera, N; Mendis, K; Jayathilaka, R; Dabare, UThe poultry industry has become one of the fastest-growing agricultural sectors in Asia, driven by rising incomes, and shifting food preferences. Therefore, this study aims to examine the relationship between chicken meat production and key determinants, including chicken meat consumption, gross domestic product, and trade openness, over 30 years (1993-2022) across 28 Asian countries. This study's foundation was based on the theories of consumer demand and international trade. Wavelet coherence and Granger causality analysis were utilised to identify the direction of causality of the variables. The Wavelet results reveal that chicken consumption and GDP become most significant with the production in the Asian continent, while Granger results reveal that most Asian countries showed unidirectional causal flows from trade openness to chicken meat production and from chicken meat production to gross domestic product and consumption. Furthermore, this study provides novel insights that inform policy considerations for policymakers, international and domestic organisations, and governments, aligning with the Sustainable Development Goals established by the United Nations.Publication Embargo E-commerce success redefined: integrating information systems and customer empowerment for e-customer engagement(Emerald Publishing, 2026-03-17) Boyagoda, G; Thalagala, S.M; Pathirana, S.L; Jeewantha, S; Wisenthige, KPurpose – This study aims to explore the impact of system quality, information quality, service quality and customer empowerment on customer satisfaction and e-commerce success in Sri Lanka, focusing on Millennials and Generation Z. By integrating the DeLone and McLean Information Systems Success (D&M ISS) model with customer empowerment theory, the research seeks to provide insights into the key drivers of e-customer engagement in e-commerce. Design/methodology/approach – A structured questionnaire was used to collect data from 413 respondents employing the purposive sampling technique. The data collection instrument comprised 32 questions related to system quality, information quality, service quality, customer empowerment and customer satisfaction, as well as demographic questions. The data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). Findings – The results revealed that the system quality, information quality and service quality significantly influence customer satisfaction and intention to use the system in the context of e-commerce, which leads to higher customer engagement. Furthermore, the findings substantiate the crucial role that customer empowerment plays in terms of increasing customer satisfaction. Research limitations/implications – This study focuses on Millennials and Generation Z e-customers in Sri Lanka. It provides insights into this demographic, but does not capture the diverse cultural and technological landscape of the entire country. The study examines Information System (IS) dimensions and customer empowerment, excluding other significant variables like overall customer engagement. Self-reported data may introduce biases, and future research with larger sample sizes and different methods could improve the validity. Focusing on four selected online shopping platforms may limit the applicability as the e-commerce landscape is continuously evolving. Practical implications – The findings offer guidance to e-commerce businesses and policymakers to enhance their digital services and customer satisfaction. Businesses can improve their system quality with intuitive designs, offering accurate information to boost engagement and deliver excellent service quality. Initiatives such as interactive tools, loyalty programs and tailored support can empower customers, fostering a stronger impact. Policymakers can support e-commerce growth by improving regulations and providing training programs. These measures contribute to a more efficient and satisfying online shopping experience, driving long-term customer loyalty and business growth. Social implications – The research emphasises the role of customer empowerment in fostering customer engagement, contributing to the growth of the digital economy and enhancing online shopping experiences. Originality/value – This research enhances the academic understanding of e-commerce success by strengthening the DeLone and McLean Information Systems Success model by adding the concept of customer empowerment. This unique improvement is applied in the context of Sri Lanka, an emerging market with its own socio-economic characteristics. This addition provides new insights into key factors affecting e-customer engagement in the e-commerce sector.Publication Embargo Economic and Environmental Drivers of Carbon Emissions in Asia: Granger Causality Insights From Foreign Investment, Inflation, and Ecological Footprint(John Wiley and Sons Ltd, 2026) Nizar, S; Natkunarasa, A; Divyanjali, H; Jayathilaka, RRising carbon emissions cause critical challenges to sustainable development, particularly in Asia which accounts for a substan-tial share of global emissions. The study investigates the short-run causal relationships between foreign direct investment, infla-tion, ecological footprint, and carbon emissions across 27 Asian countries (final analytical sample) over the period 2000–2023.Utilizing country-specific VAR-based Granger causality analysis, the study captures heterogeneous sustainability economic in-teractions without imposing uniform panel assumptions. The results reveal diverse unidirectional and bidirectional causalitypatterns, highlighting how macroeconomic pressures and environmental constraints jointly shape emission outcomes. Thesefindings underscore the importance of sustainable investment, energy price management, and institutional capacity in sup-porting sustainable communities and enhancing knowledge-driven sustainability transitions. From a managerial and policyperspective, the results provide actionable insights aligning with investment decisions, macroeconomic management, and envi-ronmental governance with the sustainable development goals, particularly SDG 13 (climate action), while recognizing country-specific development pathways.Publication Open Access Economic and environmental factors influencing beef production in high-income countries: Panel evidence(Elsevier B.V., 2026-05-06) Susan, H; Mendis, K; Perera, N; Silva, Y; Jayathilaka, RAs the global population grows, dietary patterns are shifting towards protein-rich foods, with beef production playing a critical role in balancing food security, economic growth, and environmental sustainability. Among income groups, high-income countries exhibit relatively stable, yet elevated levels of beef production compared to others, warranting focused investigation. This study evaluates the causal effects of beef consumption, greenhouse gas emissions, gross domestic product, and trade openness on beef production across 42 high-income countries from 1993 to 2022. A panel regression model with country-specific fixed effects is employed to control for unobserved heterogeneity, as supported by panel specification tests. Additionally, a simple moving average method is used to forecast short-term trends in beef production for 2023–2026. The findings reveal that there is no significant evidence to claim that there is an effect of beef consumption and gross domestic product on beef production. In contrast, trade openness negatively influences production, while greenhouse gas emissions exhibit a positive effect. Forecast results indicate increasing beef production in countries such as Uruguay, New Zealand, Ireland, Australia, Canada, and the United States. The study offers policy-relevant insights for governments and international organisations in aligning livestock production strategies with Sustainable Development Goals.Publication Embargo Expanding STEM education in low- and middle-income countries: Evidence from policy reforms in Sri Lanka(Elsevier Ltd, 2026-03-01) Priyadarshana, IGovernments in low- and middle-income countries (LMICs) are increasingly investing in STEM education to enhance youth employability and economic growth. Yet, the success of such initiatives depends on students’ responses, which are shaped by their perceptions, motivations, and institutional context. This study examines the effectiveness of two parallel government interventions in Sri Lanka aimed at increasing high school enrollment in STEM subjects: (1) introducing a new Technology stream and (2) upgrading selected schools to offer the Science stream. Using nationwide school census data from 2008 to 2021 and a Difference-in-Differences approach, the study compares the impacts of these interventions on student enrollment patterns across STEM and non-STEM majors. The results show that the introduction of the Technology stream had a significantly larger impact on increasing STEM enrollment and reducing non-STEM enrollments—especially among male students and those in provincial schools—compared to the Science stream intervention. The study draws on education economics and psychological theories to explain these differences, highlighting the roles of perceived returns, self-efficacy, and student interest orientation. The findings underscore the need for STEM policies to align with both student characteristics and broader systemic structures. Insights from Sri Lanka may be relevant to other LMICs where educational reforms must navigate stratified school systems, constrained resources, and persistent gender disparities in STEM participation.Publication Embargo Exploring Disparities in Happiness Index; among Countries with Varied Income Levels(Springer Nature, 2026-01-13) Gevindhi W.J; Dasanayaka D.R.P.U; Dewappriya N.P.R.D; Parinda A.A.K; Candauda Arachchige, SThis study examines the comparative influence of socioeconomic and governance factors on the happiness index, focusing on their relative contributions to disparities among country groups categorized by income levels: high, upper-middle, lowermiddle, and low. Using multiple regression analysis, data from the World Bank and the World Happiness Report (2010–2019) are analyzed with Fixed and Random effects models to assess the impact of these factors. The findings indicate that GDP per capita and control of corruption positively influence happiness in high-income countries, with fiscal contributions also playing a significant role. Conversely, healthcare expenditure shows a negative correlation with happiness across all income levels, suggesting inefficiencies in healthcare systems. For lower-income countries, infrastructure, governance quality, and regulatory frameworks are crucial determinants of happiness. The research underscores the varying impact of economic, social, and legal factors on happiness across different income levels, with governance improvements and healthcare system reforms identified as key areas for enhancing well-being. The study highlights the importance of context-specific strategies, where low-income countries should focus on infrastructure, corruption control, and healthcare efficiency, while high-income nations may benefit from improving governance and economic stability. This is the first study to analyze the relative impact of these factors across four groups of countries classified by income.Publication Open Access Factors influencing migration intention of undergraduates in Sri Lanka: ‘About more than employment(Elsevier Ltd, 2026-01-26) Marawila, R; Weerarathna, R; Rathnayake, N; Guruge, R; Wehella, B; Udugahapattuwa, T; Weligodapola, MThe objective of this study is to examine the factors influencing Sri Lankan undergraduates' intention to migrate. Persistent economic, social, and political challenges have driven many youngsters and professionals to leave their Country of Origin (COO). The economic collapse triggered by COVID-19 further intensified this trend, leading to a sharp increase in outward migration. Recently, a growing number of Sri Lankan undergraduates and skilled professionals have expressed a strong desire to relocate abroad, often immediately after completing secondary education. For this study, a sample of 385 undergraduates from state and non-state universities across Sri Lanka was analysed. Given the national concerns of brain drain and shortages of trained and skilled workers, the study specifically focused on understanding undergraduates' aspirations to migrate. Structural Equation Modeling (SEM) was applied to identify and test the variables influencing migration intentions within the Sri Lankan context. The findings provide a holistic picture of the drivers of undergraduate migration. These carry important implications not only for students but also for policymakers and Higher Education Institutions (HEIs), by informing policies and strategies that could encourage young people to realise their potential within Sri Lanka rather than abroad.Publication Embargo Focus on Middle East and Central Asia: rationale of IMF assistance seeking(Springer Science and Business Media Deutschland GmbH, 2026-03) Wisenthige, K; Pathiranage, H. S.K; Jayathilaka, RThis study delves into the rationale behind the tendency of nations in the Middle East and Central Asia (MECA) to seek aid from the IMF. The IMF supports global financial stability, aiming to foster economic growth and prosperity across its member countries by promoting policies that encourage monetary cooperation and financial resilience. The study employs a conditional fixed-effects logit model, the analysis spans 22 years of data from twenty-five MECA countries to identify the factors driving these nations to seek IMF assistance. It focuses on six determinants: Current Account Balance (CAB), Inflation (INF), Corruption (CORR), General Government Net Lending and Borrowing (GGNLB), General Government Gross Debt (GGGD), and Gross Domestic Product Growth (GDPG). The fixed-effects logit shows that slower GDP growth raises the odds of an IMF programme, while short-run changes in corruption control and public debt ratios are not significant once country and year effects are absorbed. Inflation is weakly positive; the current account balance is still insignificant. A post-GFC and an income-group robustness check confirm the pattern. Furthermore, the study identifies Lebanon, a lower-middle-income country, as a leading example of seeking IMF assistance during the study period. Overall, this research highlights the importance of policymakers understanding the dynamics and rankings within the MECA region to effectively address economic challenges, provide financial support, and foster a more sustainable economic structure.Publication Embargo From Learners to Earners: The Role of Education in Shaping Online Freelancers within the Gig Economy(University of Nigeria Department of Mass Communication, 2026-01-05) Dasanayaka, L.N; Madanayake, T.B; Jayasekara, K.G; Ileperuma, T.D; Chandrasiri, R; Bandara, GIn developing nations, education systems prioritise employability over broader academic goals, often overlooking the preparation needed for freelance platforms. Yet, the digital economy presents a rapidly expanding avenue for youth employment and economic empowerment. This systemic oversight leaves many undergraduates unprepared to capitalise on the increasing global demand for digital and professional freelance services. Objective: This study aims to identify the attitudes, behaviours, and skills that undergraduates need to succeed in online freelancing, addressing the knowledge gap between the popularity of digital self-employment and the factors driving undergraduate success in this field. Methodology: This study employed an inductive approach, focusing on undergraduate freelancers in Sri Lanka. Snowball sampling was utilised to select 21 participants, and in-depth interviews were conducted to collect data. The data were subsequently analysed using NVivo thematic analysis, with analysis continuing until saturation was reached. Results: The results of this study revealed six key themes that significantly impact making an online freelance career for undergraduates in Sri Lanka: (I) Growth Mindset, (II) Work-life balance, (III) Flexibility, (IV) Effective Communication, (V) Proactive engagement and (VI) Developing Core Competencies Conclusion: Although the rising popularity of freelancing online among undergraduates is a significant trend, success is primarily attributed to various factors that enable freelancers to reach their full potential. Addressing these factors will be the solution to helping undergraduates navigate the online freelancing field. Unique Contribution: This study makes a significant contribution by empirically identifying and systematically categorising the key competencies required for undergraduate success in transitioning to online freelancing. It provides a novel, evidence-based framework for educators and policymakers seeking to prepare students for sustainable career opportunities and economic empowerment in the digital economy (SDG 8). © 2025, University of Nigeria Department of Mass Communication.

However, the extent to which tourism contributes to sustainable development depends on macroeconomic stability and policy environments that enable long-term investment rather than short-term revenue maximisation. This study examines the causal relationships between tourism receipts, per capita GDP (PGDP), and exchange rates across 46 Asian countries from 2000 to 2020, while controlling for trade openness to account for broader external sector exposure. Employing a panel data framework that accounts for cross-sectional dependence, heterogeneity, and mixed integration properties, the analysis combines second-generation unit root and cointegration tests with country-specific Granger causality techniques. The findings reveal substantial heterogeneity in causal dynamics across countries. In some economies, tourism-led growth emerges, where expanding tourism receipts stimulate economic growth. In others, economy-driven tourism dominates, indicating that rising income levels facilitate tourism development through improved infrastructure and destination competitiveness. Exchange rate stability plays an important conditioning role, shaping the extent to which tourism revenues translate into sustained development gains. Countries characterised by stable exchange rate environments are better positioned to channel tourism income toward long-term, sustainability-oriented investments. The study offers actionable policy insights by demonstrating that macroeconomic stability is a prerequisite for sustainable tourism development. Strengthening exchange rate governance, promoting eco-friendly tourism investment, and enhancing regional cooperation can support a transition from growth-oriented tourism strategies toward sustainable development pathways.Publication Open Access Global economic uncertainty shocks and macroeconomic dynamics before and after COVID-19: Evidence from Africa and the Americas(Elsevier Inc., 2026-04-03) Madurawala, R; Navamohan, P; Gamage, D; Hansika, S; Jayathilaka, RGlobal economic uncertainty has become a central driver of macroeconomic instability, particularly during large-scale crises like the COVID-19 pandemic. This study examines how global uncertainty shocks affect key macroeconomic variables, particularly suicide rates, economic growth, unemployment, and trade openness across 62 countries in Africa, South America, and North America over the period of 2004–2023 as the countries in these regions exhibit the highest uncertainty post-pandemic. Utilising the COVID-19 pandemic as a natural experiment, the analysis distinguishes between pre- and post-pandemic uncertainty-socioeconomic dynamics to assess the bidirectional and cointegrating relationships across regions. The study employs Multiple Linear Regression to capture short-term macroeconomic responses and panel and country-level cointegration techniques to identify long-run relationships between economic uncertainty and macroeconomic variables. Global uncertainty is proxied using the World Uncertainty Index, which captures broad policy, geopolitical, and crisis-related uncertainty affecting expectations and real economic activity. Unlike, existing studies which reveal insights in a particular region or country, the current findings uncover bi-directional relationships in 21 countries post-pandemic, with notable relationships in Algeria, Botswana, Gabon, Guinea, Madagascar, Republic of Congo, Dominican Republic, Mexico, Bolivia, Paraguay. Moreover, long-run cointegration between uncertainty and macroeconomic indicators strengthens in the post-COVID-19 period, particularly in countries of Africa and North America. By analysing countries in the highest uncertainty regions the study contributes to the international macroeconomics literature by providing new evidence on how global uncertainty shocks reshape macroeconomic dynamics across regions with heterogeneous economic structures, offering important implications for macroeconomic stabilisation in an increasingly uncertain global landscape.Publication Open Access Impact of climate change on agricultural production efficiency in leading agriculture-producing economies: A DEA Malmquist Productivity Index(Elsevier B.V., 2026-01-06) Ahmad, J; Wang, Y; Zhang, L; Shah, W.U.H; Yasmeen, R; Pathiranage, H.S.KClimate change significantly impacts global agricultural productivity, making it essential to examine its precise influence on production efficiency. This study evaluates the impact of climate change on agricultural production efficiency among the global leading agriculture-producing economies from 1990 to 2021. Using a DEA–Malmquist Productivity Index, the study estimates total factor productivity change (TFPC) and decomposes it into efficiency change (EC) and technological change (TC), both without and with explicit climate variables (temperature, precipitation). Average TFPC without climate factors is 1.0428, indicating 4.28 % productivity growth over the period, primarily driven by technological change. When climate variables are incorporated, the average TFPC is 1.0409; the mean difference of −0.0019 (≈ −0.18 %) shows a small but non-negligible climate impact on productivity growth. Regional variations are heterogeneous: South America and Africa exhibit diverse climate impacts, while Oceania shows the least climate effect. Mann-Whitney U and Kruskal-Wallis tests confirm significant differences in TFPC (and components) between climate and non-climate specifications and across regions. The findings underscore technology's key role in sustaining productivity under climate stress and highlight the need for region-specific adaptation policies to complement technological diffusion.Publication Open Access Impact of climate change on agricultural production efficiency in leading agriculture-producing economies: A DEA Malmquist Productivity Index(Elsevier B.V., 2026-03-01) Ahmad, J; Wang, Y; Zhang, L; Shah, W.U S; Yasmeen, R; Pathiranage, H.S.KClimate change significantly impacts global agricultural productivity, making it essential to examine its precise influence on production efficiency.

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.
