Addressing it is more than a question for health systems; it must be embedded as a central concern in climate and environmental policy.
This is being urged by scientists from Heidelberg University whose research focuses, among other things, on global health, environment-related diseases and climate action. They advocate not only countering this inequality at the individual level but also removing its structural causes. In a paper published in the journal Nature Human Behaviour, they explain the approaches required in research and policymaking.
The authors underline that seven of the eight "safe and just Earth system boundaries" have already been transgressed—boundaries that represent the stability and resilience of the whole planet and also take account of equity for all people. Accordingly, a large part of the global population is affected by these boundary transgressions, with impacts distributed unequally worldwide. The Heidelberg researchers state that low- or middle-income countries are being disproportionately affected, as are poorer and older population groups within high-income regions.
"Prosperity and greater financial latitude enable people to better protect themselves from climate and environmental crises without having to change their consumer habits—habits that contribute to the planetary crisis. This inequality is a key obstacle to health equity, which should offer the greatest possible potential for a healthy life to all individuals, regardless of their social, economic or geographic situation. Combating it is linked to the question of what contribution climate policy and climate action can make," said political scientist Dr.
She is the scientific coordinator of Heidelberg University's Climate-Life-Nexus Flagship Initiative, which is set to begin its work soon and focus on interdisciplinary research on climate-health interlinkages. According to Professor Dr. Joacim Rocklöv, a scientist at the Heidelberg Institute of Global Health and the Interdisciplinary Center for Scientific Computing, health risks entailed by the triple planetary crisis are rarely due to a single threat.
"Heat, environmental pollution, climate-related infectious diseases and limited resources can occur at the same time, and these risks don't just add up—they strengthen one another," said the epidemiologist, mathematician and statistician. He is the director of the Heidelberg Planetary Health Hub at Heidelberg University and one of the two coordinators of the European Lancet Countdown Report on Health and Climate Change. Rocklöv said, "We have to take a comprehensive view of these threats in order to identify the most impacted population groups and develop effective measures." Geoinformation scientist Professor Dr.
