HIGHLIGHTS: *Using information gathered from visits to field sites and interviews with farmers in 2019, the authors of this report or Guidance Memo document the challenges faced by socially and economically-marginalized women in the Northern Mountainous Region (NMR) of Vietnam who raise local or heritage pigs on small-scales to supplement their family income. *These women have been greatly affected by recent growth in industrial-scale pork production in Vietnam. *Moreover, the African Swine Fever crisis in northern Vietnam in mid/late 2019 threatens to put an end to raising local/heritage breeds on small scales in NMR. *But there is clear evidence that smaller-scale pork production in NMR is viable and is good socially, economically, environmentally, and for animal welfare. *A number of concrete, practical ways to support small-scale producers are suggested, from providing training in pig breeding to simple steps like teaching the small producers to use Facebook to attract customers.
