Mental health impacts can emerge as result of climate impacts on economic, social and food systems . For example, malnutrition among children has been associated with a variety of mental health problems , as has food insecurity among adults . The economic impacts of droughts have been associated with increases in suicide, particularly among farmers ; those whose occupations are likely to be affected by climate change report that it is a source of stress that is linked to substance abuse and suicidal ideation . Studies of Indigenous Peoples often describe food insecurity or reduced access to traditional foods as a link between climate change and reduced mental health . The loss of family members, for example due to an extreme weather event, increases the risk of mental illness . Individuals in low- and middle-income countries may be more severely impacted due to lesser access to mental health services and lower financial resources to help cope with impacts compared with high-income countries .
