Public Health Implications of Drought in a Climate Change Context: A Critical Review

Annu Rev Public Health. 2023 Apr 3:44:213-232. doi: 10.1146/annurev-publhealth-071421-051636. Epub 2023 Jan 9.

Abstract

Extreme weather events are expected to increase due to climate change, which could pose an additional burden of morbidity and mortality. In recent decades, drought severity has increased in several regions around the world, affecting health by increasing the risk of water-, food-, and vector-borne diseases, malnutrition, cardiovascular and respiratory illness, mental health disorders, and mortality. Drought frequency and severity are expected to worsen across large regions as a result of a decrease in precipitation and an increase in temperature and atmospheric evaporative demand, posing a pressing challenge for public health. Variation in impacts among countries and communities is due to multiple factors, such as aging, socioeconomic status, access to health care, and gender, affecting population resilience. Integrative proactive action plans focused on risk management are required, and resources should be transferred to developing countries to reduce their vulnerability and risk.

Keywords: climate change; drought risk management; drought trends; human health; vulnerability.
