This work is devoted to analyzing the pros and cons of the proposed San Ign
acio Lagoon (SIL) salt production project in Baja California Sur, Mexico. T
he analysis of the project was done taking into account the technical data
of the main potential effects of the SIL project, and by comparing the SIL
proposed actions with the data of Ojo de Liebre Lagoon, where an almost ide
ntical salt production project has been operating for more than 44 years. T
he analysis was done from the following perspectives: biodiversity, biosphe
re reserve management, and socioeconomic development. The resulting analysi
s of the pros and cons of the SIL salt production project addresses key asp
ects of sustainable development in Third World nations. The resulting analy
sis indicates that the SIL salt production project is compatible with the b
iodiversity conservation of the zone. The SIL salt production project seems
to be one of the best options to attain the sustainable use of natural res
ources of the most arid and isolated zone of all Mexico.
