Analyzing potential effects of migration on coastal resource conservation in Southeastern Ghana

Coastal areas are under increasing pressure from rapid human population growth, yet empirical research on the effect of migration on coastal and marine resources is scarce. We contribute to this understudied literature by conducting an original household survey in a coastal region of Southeastern Ghana. This study employs two proxies for pro-environmental behavior that have not, to our knowledge, been used in the context of coastal migration, to explicitly compare migrant and non-migrant populations. Environmental attitudes toward coastal resources and individual extraction behavior in common-pool resource (CPR) experiments have shown broad relevance in the literature to understand natural resource decision making. We found that migrants in general did not differ significantly from non-migrants in relation to their environmental attitudes or their extraction behavior in the CPR game. However, when focusing on migrant fishers only, results suggested that this subgroup was less concerned about the utilization of coastal resources than non-migrant fishers and behaved less cooperatively in the CPR experiment. These findings, though, held true only for the subgroup of fishers, and could not be found for other occupational groups. Therefore, we conclude that migrants do not per se value coastal resources less or cooperate less in CPR situations, but that socioeconomic characteristics, and particularly their occupational status and their relation to the resource, matter.
