2014; Musah-Surugu et al., 2018; Mashizha, 2019). While there is extensive documentation on the benefits of migration, the quality of studies is such that links between migration and subsequent benefits are not clear, making our conclusion of benefits from this measure as having medium confidence. On the other hand, there is more rigorous evidence on the maladaptive nature of migration as an adaptation measure . However, adverse climatic conditions, especially droughts, have been found to reduce international migration, as resources are unavailable to consider this option , resulting in limits to adaptation . In addition, it is difficult to model this option in future climate adaptation models.
