Abstract

This paper presents a mathematical modeling framework of a competitive multiperiod agricultural supply chain network under the triple bottom line sustainability, comprising financial, environmental, and social aspects. In our competitive supply chain modeling framework, agri-food firms strategically determine the flows of agricultural products to demand markets, the scale of farmland used for sustainable and conventional farming practices, and the allocation of labor for both sustainable and conventional farming practices. Profits determine the financial sustainability component, while environmental sustainability is assessed based on the total greenhouse gas emissions generated and the amount of water consumed. Social sustainability is measured through a social benefit function that considers the labor employed for both sustainable and conventional farming practices, as well as agri-food firms’ overall economic contribution through agricultural production in the regions. The competition between agri-food firms is studied through game theory, where the governing Generalized Nash equilibrium conditions correspond to a variational inequality problem. We use the Euler method as the algorithm to analyze a numerical study focusing on avocado supply chains. We draw attention to the potential impacts of climate change and deforestation in our numerical study. Given the trade-offs, our findings highlight the importance of achieving the triple bottom line.
