  7. Household pork consumption behaviour in Vietnam: Implications for pro-smallholder pig value chain upgrading por Nga Nguyen Thi Duong, Nguyen Thi Thu Huyen, Pham Van Hung, Duong Nam Ha, Tran Van Long, Dang Thi Be, Unger, Fred, Lapar, Ma. Lucila

    Publicado 2015
    “…Given saturated pork demand with more than 95% of respondents planning to sustain or decrease their pork consumption, it’s unlikely that pork consumption behaviour will significantly change for the majority of Vietnamese consumers. Several potential implications are drawn for upgrading the pig value chains: (i) Organizing small farms into groups applying good practices that allow meat to be traceable and certified by trusted institutions; (ii) Developing a quality assurance system that can be feasibly established under smallholder conditions, and complies with minimum quality and safety standards tailored to Vietnam’s context, (iii) Strengthening capacity to collect appropriate market information to provide pig producers, particularly smallholders, reliable meat demand and supply forecast to better serve their target consumers; and (iv) Improving cost and quality competitiveness in pig value chains. …”
