Migration and Climate Change: The Mexican Case

The June 2009 issue of Migration Watch Mexico by the BBVA Bancomer Foundation and BBVA Research mentioned the importance of environmental phenomena as factors of population expulsion or attraction. Expulsion occurs when in the communities of origin the environment begins to be detrimental to the life of human beings; for example, when there is environmental degradation and new risk zones appear, or when land is limited. In turn, the environment is a population attraction factor when the ecological quality of the environment is better compared to the zones of origin, thereby motivating migration.
