Impact of Green Supply Chain Practices on Sustainability in Sri Lankan Tea Export Sector: A Systematic Literature Review

Abstract

GSCM is one of the most crucial strategies that incorporate sustainability into operational and production practices. Based on this premise, the given systematic literature review examines how the key GSCM practices influence sustainability in Sri Lanka's tea export sector. This review identifies synthesized findings from various studies that the adoption of GSCM has led to a significant improvement in economic sustainability through a reduction in operational costs of up to 20%-and enhancing the ability of market competitiveness. In this regard, environmental concerns contribute by reducing resource consumption by up to 30% as waste is generated, promoting sustainable production processes. Socially, GSCM advances good labor practices and strengthens community involvement in the pursuit of better working conditions, improving relationships between the producers and local communities. With all these advantages, however, GSCM in the Sri Lankan tea export sector faces fluctuating global market prices, effects of climate change, and persistent labor shortages. These challenges are indicative that strategic interventions of the government to support and collaborate in the industry do become urgent to enhance sustainability. This review also points out one important limitation in relying on secondary sources of data and emphasizes that there is a dire need for empirical research to enhance the evidence base to provide actionable insights for policymakers and stakeholders. In sum, this literature review underlined that GSCM played a vital role in the advancement of sustainability within the tea export sector and in providing a competing position of the industry in a global market for long-term viability in sustainability
