Assessment of the effectiveness of high-tech agricultural development policies on the Co Ho ethnic group in Lac Duong District, Lam Dong Province

High-tech agricultural development has become a key strategy to enhance productivity and sustainability in rural areas, particularly among ethnic minority communities with limited access to modern technologies. This study examined the effectiveness of policies promoting high-tech agriculture among the Co Ho ethnic group in Lac Duong District, Lam Dong Province, Vietnam. A mixed-methods approach was applied, including structured surveys of 364 households, in-depth interviews, and focus group discussions with local stakeholders. Quantitative data were statistically analyzed, while qualitative data provided contextual insights. The findings indicated high awareness and initial adoption of accessible technologies such as improved crop varieties, drip irrigation, and smart fertilizers; however, only a small proportion of households fully understood policy content and procedures. Significant barriers included financial constraints, inadequate infrastructure, and traditional cultural practices. Although market connectivity and labor efficiency improved, productivity and income increased moderately. The study concluded that while current policies facilitated early technology adoption, knowledge gaps, financial limitations, and socio-cultural factors hindered sustained economic benefits. To improve policy effectiveness, integrated interventions addressing financial accessibility, advanced technical training, infrastructure development, and culturally sensitive communication were recommended to support equitable and sustainable agricultural modernization among ethnic minority farmers.
