DEVELOPING OFF-SEASON ORGANIC VEGETABLE PRODUCTION MODELS BASED ON VALUE CHAINS TO HELP FARMERS ADAPT TO CLIMATE CHANGE AND MARKET DEMANDS

Abstract

Off-season organic production of temperate vegetables refers to the cultivation of crops such as tomatoes and radishes during the summer months in Northern Vietnam. This study aims to develop an off-season organic vegetable production model based on value chains for farmers, taking advantage of the favorable highland climate while enhancing their ability to adapt to both climate change and market demands. Organic agriculture is considered a climate-resilient production method that meets market needs and contributes to increased income for farmers. The research successfully established off-season organic production models for tomatoes and radishes certified to meet the Vietnamese organic standards (TCVN11041-2:2017) in the highland commune of Van Son, Tan Lac district, Hoa Binh province. Off-season yields reached 34.6 tons/ha/crop for tomatoes and 36.42 tons/ha/crop for radishes. The economic efficiency of the off-season organic tomato model reached 890.92 million VND/ha/crop, while the off-season organic radish model reached 438.97 million VND/ha/crop. The study also developed a value chain-based model for managing and marketing organic vegetable products for farmers in Van Son commune, providing a foundation for scaling up the model in the future.
