From global to local: challenges to reduce health risks related to climate change, disasters, and Public Health Emergencies

Abstract

For the first time in history, transformations in the expected pattern of the climate are witnessed with consequences still unknown for modern industrial society. These global risks occur in an increasingly connected world, with a growing and environmentally degraded population, against the background of a scenario in which there is a proportionately inverse relationship between countries, populations and social groups that suffer, in a broader and more intense way, the risks and damages caused by climate change. One of the immediate impacts already observed is the increase in the frequency and magnitude of extreme events, generating scenarios favorable to the emergence of health emergencies. This article aimed to present the main challenges for reducing health risks related to climate change, disaster and Public Health Emergencies;
the main advances in policies on the subject; and health actions within this complex imminent social, environmental and health scenario. As a result, the main related global agreements and the needs to expand the National Health Risk Reduction System are presented, aiming at strengthening the necessary actions, in order to obtain an adequate response to the risk factors presented. To this end, six recommendations are presented that are necessary for the elaboration of this system.
