Abstract
Climate change poses major challenges to Vietnamese agriculture, requiring stronger adoption of sustainable technical practices (STPs). This study surveyed 337 farming households in four communes of Hue City to assess the current situation and identify factors influencing the adoption of STPs in crop production. Results indicate that eight types of STPs are commonly applied, including composting organic fertilizers, water-saving irrigation, VietGAP/organic production, integrated pest management (IPM), use of bio-products, crop rotation/intercropping, soil improvement with biological agents, and recycling of agricultural by-products. Among these households, 45.7% adopted at least one STP and reported higher average incomes than non-adopters. Multiple regression analysis (R² = 0.587) revealed four factors with significant positive effects on adoption: knowledge of climate change (β = 0.411), farm size (β = 0.254), participation in community organizations (β = 0.182), and access to credit (β = 0.137). The study recommends enhancing climate change awareness, improving agricultural extension services, strengthening farmer organizations, and refining credit policies to expand the adoption of sustainable practices.
