Faktory ovlivňující udržitelnou produkci s ekonomickým růstem v kávovém průmyslu: Studie z Vietnamu

Abstract

The study used the Cobb-Douglas production function to evaluate the cost-effectiveness and profitability of sustainable coffee production in four of the largest coffee-growing provinces in Vietnam. By analyzing data from 864 farming households, the study compared the performance of sustainable and conventional coffee growers. The results showed that contrary to initial predictions, sustainable coffee production was more efficient than traditional methods. Important factors affecting yields include farm size, organic fertilizers, and certification. Expanding the planted area contributed to increased yields in both production models. In particular, organic fertilizers increased yields protected the environment, and maintained biodiversity, while inorganic fertilizers (NPK) significantly impacted conventional coffee. Combining these two fertilizers promoted growth and profitability in both farming systems. Furthermore, actual land prices also have significant effects on coffee output. The study confirms that sustainable coffee production is more cost-effective and brings economic and environmental benefits. The research results provide helpful information for coffee growers, local authorities, and policymakers in Vietnam and can be widely applied.
