Production and marketing of tilapias in Central Thailand is diverse in form and
significant in scale. The sustainability of livelihoods associated with tilapia culture is
influenced by numerous factors. Region based urbanization, economic performance at
the farm level, and internal and external environmental factors are identified as the
key determinants of sustainability in this context. These are explored in detail with
reference to the results of primary field-based research and supporting secondary data.
The interaction of these elements is described and their implications are discussed vis
a vis system and livelihood sustainability.
