This report examines indigenous fruit and vegetable systems in Northern Vietnam, focusing on Mai Son district in Son La and Sa Pa in Lao Cai. The study highlights the important role of indigenous crops such as H’Mong mustard, H’Mong cucumber, Tả Van plum, mountain peach, local pumpkin, and traditional mango varieties in supporting livelihoods, nutrition, biodiversity conservation, and agro-ecotourism. Production is mainly small-scale and based on traditional knowledge, with limited use of fertilizers and pesticides. However, farmers face challenges including inconsistent product quality, weak market linkages, poor seed systems, limited post-harvest handling, and lack of certification or branding. Despite these barriers, demand for culturally distinctive and locally sourced products is increasing, especially from tourists, restaurants, homestays, and urban consumers. The report identifies strong opportunities to improve value chains through cooperative development, agroecological farming, OCOP branding, safe production standards, digital marketing, and agro-tourism integration. Strengthening producer organizations, seed systems, and market connections can help preserve indigenous biodiversity while increasing income and resilience for ethnic minority communities in Northern Vietnam.
