    Socio-Economic and Environmental Drivers of Food Security in Low-Income Countries: A 32-Year Cross-National Analysis for Sustainable Development
    (John Wiley and Sons Ltd, 2026-04-06) Pulle, N; Sampath, P; Wijayaweera, D; Perera, S; Jayathilaka, R; Dabare, U
    Ensuring countries meet their basic food security needs has been a long-standing challenge. Despite numerous attempts to tackle this issue, it remains unresolved. Hence, considering the broad reach of this concern, our study aims to collectively analyse how urbanisation, greenhouse gas emissions, renewable energy consumption, population growth, agricultural land, and gross domestic product per capita impact food security across countries. This study tests a stepwise panel-ordered probit model, utilising data from 17 low-income countries from 1992 to 2023. The research categorises the food production index into three categories: low, moderate, and high food security, allowing for the analysis of the likelihood of falling into a category of the food production index. The outcomes reveal that in low-income countries, urbanisation, greenhouse gas emissions, population growth, and agricultural land have a positive impact on the food production index, whereas renewable energy consumption has an insignificant negative impact. This analysis contributes distinctively to the existing body of knowledge by comparatively analysing the probabilities over the given period, together with the financial crisis and the COVID-19 pandemic, thus providing insights into both events. Furthermore, this report highlights the effectiveness of policies implemented, focusing on the efficient use of agricultural land through technological advancements, promoting modern farming techniques, encouraging youth engagement in agriculture, managing population growth, and innovating climate-resilient strategies, which are directly aligned with the research findings. These recommendations address specific challenges identified in the highlighted countries, helping improve their food security and promote sustainable development.

    Investigating the Effects of Beef Consumption, Trade Openness, and Cattle Population on Beef Production in North America
    (Springer, 2026-08) Susan, H; Silva, Y; Perera, N; Mendis, K; Jayathilaka, R; Dabare, U
    We examine how beef consumption, trade openness, and cattle count influence beef production across 14 countries from 1993 to 2022 using panel and multiple linear regression analyses. The findings show that beef consumption and cattle count have positive effects, while trade openness has a mixed effect on beef production when analyzed individually. These effects vary across countries due to factors such as quality and safety standards, bovine diseases, export and import barriers, trade policies, land availability, pasture conditions, veterinary services, and biosecurity knowledge. Our study highlights the need for strategies to improve these factors and demonstrates how such strategies align with the UN Sustainable Development Goals (SDGs).

    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, U
    The 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.

    Unlocking cinnamon export success: Key determinants from the world's top five producers
    (Public Library of Science,PLOS ONE, 2025-12-11) Wisenthige, K; Jayathilaka, R; Dabare, U; Marasinghe, T; Radeesha, M; Ann, F; Kavindya, N
    The purpose of this research study is to identify the factors affecting cinnamon export income (CEI) in the main five cinnamon export countries, namely China, Sri Lanka, Indonesia, Madagascar and Vietnam for the period from 1992–2022. Secondary data was sourced from the Food and Agriculture Organization and World Bank. Based on the past literature, it has been found out that production volume (PV), domestic consumption (DC), exchange rate (ER) and cultivated land area (CLA) significantly impact on CEI. Simple Linear Regression models were applied to analyse the impact of the identified factors affecting CEI in the present study. The findings revealed, PV negatively impacts the export income of cinnamon in China, Sri Lanka, and Vietnam, while having a positive impact on Indonesia and Madagascar. Moreover, while DC appears to have a positive impact in Sri Lanka, it has a negative impact in China, Vietnam, Indonesia and Madagascar for the same. Accordingly, ER is positive for countries Madagascar, Sri Lanka, and Vietnam while adverse for Indonesia and China. In addition, the study proved that CLA positively influences CEI of China, Vietnam, and Madagascar but negatively for Sri Lanka and Indonesia. Consequently, the findings from this study greatly assist policymakers, exporters, and the industry professionals in executing strategies to enhance the export income & thereof export practices of cinnamon. Finally, this research addresses several gaps in cinnamon export studies, supporting sustainable growth and competitiveness in the sector.
