Market System Adaptation to Climate-Smart Agriculture: A Case of the Sorjan-Induced Bio-Economy in Coastal Bangladesh

Abstract— This study evaluates the transformative impact of the Climate Adaptive Sorjan Model on the agricultural market system in the coastal regions of Bangladesh, particularly in Charfasson and Lalmohan, Bhola. The research highlights how the adoption of this raised-bed and ditch farming system has catalyzed significant shifts in both backward and forward market linkages, fostering a sustainable and resilient agribusiness ecosystem. Key findings reveal a substantial expansion in the backward market for eco-friendly agricultural inputs, with bio-pesticide sales increasing by nearly 20% within a year and the number of input suppliers more than doubling in the region. This growth reflects a systemic shift toward ecological farming practices driven by farmer adoption of integrated pest management and organic fertilization. In the forward market, Sorjan-produced vegetables have achieved extensive penetration into national wholesale hubs, with over 80% of produce traded beyond local markets. The model’s diversified, year-round production has attracted trader investment, ensured price premiums, and stimulated the development of a more resilient value chain. However, challenges such as post-harvest infrastructure gaps and price manipulation by middlemen persist. The study concludes that the Adaptive Sorjan Model not only enhances on-farm resilience and productivity but also actively reshapes local and regional market systems, creating a self-reinforcing cycle of demand for green inputs and premium produce. Strategic interventions in finance, market access, and supply chain development are recommended to sustain and scale this market-led climate adaptation pathway.
