million tonnes per year. This expansion was accompanied
by increased resource use and environmental pressure,
leading to non-governmental organisations and international
press expressing their concern about the use of

addressed these concerns in a 2020 Master Plan for the
Pangasius production sector in the Mekong delta. This
paper reports the environmental impact assessment (EIA)
supporting implementation of this 2020 Master Plan.
