Understanding Coffee Certification Dynamics: A Spatial Analysis of Voluntary Sustainability Standard Proliferation

Abstract

Third-party Voluntary Sustainability Standards (VSS) have emerged as an increasingly popular strategy to guarantee sustainability in the coffee value chain. Yet, knowledge of the population characteristics of certified farmers, and of the influence of transnational and local supply chain actors on the uptake of VSS at the producer level, is still scarce. Using expert interviews, a comprehensive database of certificate holders and spatial mapping analyses, this paper adds to present knowledge concerning the effectiveness of VSS in the coffee sector in three ways. First, it showcases the structural, geographical and socio-economic tendencies toward VSS adoption in Guatemala, Colombia and Costa Rica, and allows first insights in the additionality and effectiveness of certification schemes derived from these indicators. Second, it contributes to an up-to-date understanding of the coffee supply chain, a sector of great economic importance both to producing and consuming countries that is in constant flux and reorganization, and it explains how current VSS interact with this type of global supply chain. Finally, through the construction of a comprehensive population of certified farmers, it enables better evaluation of existing case studies, generalizability, possible biases and provides valuable information for the preparation of future impact evaluation projects.
