WHAT IS PLANETARY HEALTH?
Displacement and Conflict
The Earth crisis is significantly leading to a range of socio-political and humanitarian crises.
Environmental degradation–such as desertification, deforestation, and rising sea levels–forces millions to leave their homes, contributing to a growing population of climate refugees and internally displaced persons. In the past decade, weather-related events have driven an average of 21.5 million people from their homes each year, a figure that surpasses displacements caused by conflict and violence by more than twofold.

Rising sea levels threaten the existence of small island states, while water shortages and agricultural collapse in arid areas contribute to increased migration. These movements, within and across borders, often place immense pressure on resources in destination regions, leading to competition for essentials such as food, water, and land, which can escalate into conflicts over resources and civil unrest .
A recent UNHCR report highlights that individuals fleeing war, violence, and persecution are increasingly vulnerable to the global climate crisis and other forms of environmental degradation. These overlapping challenges place them in a precarious position, facing compounded threats while lacking adequate funding and resources for adaptation.

Displacement caused by environmental crises and conflict is strongly associated with increased risks of infectious disease outbreaks, malnutrition, and both physical and mental trauma. Overcrowded and unsanitary conditions in displacement camps, coupled with limited access to healthcare and clean water, create ideal conditions for the spread of diseases such as cholera and respiratory infections. Malnutrition often becomes more severe among displaced populations due to disrupted food systems and insufficient aid supplies. Addressing these challenges requires urgent global collaboration and evidence-based policies to mitigate the profound human toll of forced displacement.
