Health and Migration, Environment and Climate Change

Climate change is expected to result in a higher frequency of climate-related health hazards and fatalities due to malnutrition, increased propagation of vector-borne diseases such as malaria and dengue and heat stress, among others. The number of people migrating because of the adverse impacts of climate change and environmental degradation on their livelihoods, daily lives and health is also expected to rise.

Many migrants moving in the context of climate change, environmental degradation and natural disasters have specific physical and mental health needs that are linked to their exposure to climate and environmental conditions. Yet, these migrants often experience significant barriers to accessing essential health and social services.

The COVID-19 crisis highlights that the migration, climate change and health nexus needs to be urgently prioritized, as many migrants experience increased vulnerability.

In this context, IOM is intensifying its efforts to develop joint action across its climate migration and migrant health work streams. 

This page compiles a list of IOM documents and other relevant resources that can be useful to understand the migration, environmental, climate change and health nexus.
