Sustainability Standards in Agri‐Food Value Chains: Impacts and Trade‐Offs for Smallholder Farmers

The global agri‐food system faces major challenges in meeting the growing demand for food in an equitable way while mitigating environmental impacts such as deforestation, soil degradation, and climate change. Over the past few decades, voluntary sustainability standards (VSS) have proliferated as a potential instrument to promote more sustainable global value chains and sourcing practices. Although the body of impact evaluations on VSS has grown, most studies focus on single outcome dimensions, leaving interactions between dimensions underexplored. In this study, we use a conceptual framework to assess the relationships between VSS interventions and key sustainable food system outcomes across multiple dimensions. Our study focuses on economic prosperity, healthy ecosystems, gender equality, and food security, with a particular emphasis on identifying potential trade‐offs and synergies between these dimensions. To illustrate the interactions identified in our framework, we present empirical data from three case studies in Ghana, Rwanda, and Peru. Our findings underscore the importance of balancing trade‐offs and fostering synergies to advance sustainability across multiple dimensions. This study contributes to ongoing discussions on the effectiveness of VSS in promoting sustainability by highlighting their potential impacts, as well as the trade‐offs that must be managed, to achieve more sustainable food systems.
