Effects of natural disaters on migration

Prior research has primarily focused on the impact of single, large disaster events but very little is known about how small and moderate disasters, which are more typical, affect population health.

In this paper, we present one of the first investigations of the impact of small and moderate disasters on childhood morbidity, physical growth, and immunizations by combining household data on over 80, children from three waves of the Indian National Family and Health Survey with an international database of natural disasters EM-DAT.

Exposure to a disaster in the past year reduces height-for-age and weight-for-age z-scores by 0. Most notably, the adverse effects on growth outcomes are much smaller among boys, infants, and families with more socioeconomic resources. India, natural disasters, child health, immunization, stunting, underweight Introduction Natural disasters are a common occurrence in developing countries, and there is growing concern that they may become more frequent due to climate change Van Aalst, Disasters result in significant economic damage and can cause large-scale death.

In addition to their immediate effects on health and mortality, disasters can have indirect, long-term, population health effects through various mechanisms, including income shocks to households and restricted access to health care.

In particular, exposure to disasters during critical growth phases, such as childhood, could permanently alter health trajectories by interrupting important health investments.

For example, disasters may prevent children from receiving timely immunizations or may induce households to divert resources away from children. While understanding the effects of large disaster events is important, nations are more frequently affected by smaller-scale disasters, sometimes repeatedly.

In fact, large disasters typically attract greater international aid and resources to the affected regions Stroemberg,potentially mitigating some adverse effects. In contrast, smaller disasters often do not receive as wide attention and may lead to significant detrimental effects on child health and access to health care, even if immediate effects on mortality may be small.

Consequently, impacts of large-scale disaster events may not be generalizable to the majority of disasters, particularly for developing countries.

However, a majority of these disasters did not result in large fatalities, and there has been no systematic examination of whether exposure to these disasters affected morbidity, nutrition, and health investments in childhood.

This effort represents the first time that the EM-DAT data have been linked to micro-level household survey data, enabling a comprehensive assessment of the impact of natural disasters and not just single disaster events.

By destroying, damaging, or straining health infrastructure, natural disasters might affect access to health care.
