floods or droughts can hinder population mobility, immobilising them in their localities . These immobilised populations are supposed to face a double set of risks: they are unable to move away from environmental threats, and their lack of capital makes them especially vulnerable to environmental changes . In CSA, migrating to the US is becoming dangerous and expensive because that country is restricting entry; these trends expose local populations to the risk of becoming immobile in the near future in a place where they are extremely vulnerable . A survey in Guatemala found no correlation between migration to the US and severe food insecurity in households, but the correlation became significant if the level of food insecurity was moderate, suggesting that families in extreme hardship did not have the resources to migrate . At the same time, some populations just have chosen not to move, as in Peru, where immobility among dissatisfied people is more likely to be caused by attachment to place than resource constraints . Some populations have chosen to adapt relying on their IKLK .
