Agenda: Climate Refugees in The Uncertainty of Being a Refugee or Migrant and Protecting Refugees, Reducing Effects of Climate Crisis
The impacts of climate change are numerous and may both trigger displacement and worsen living conditions or hamper return for those who have already been displaced. Limited natural resources, such as drinking water, are becoming even scarcer in many parts of the world that host refugees. Crops and livestock struggle to survive where conditions become too hot and dry, or too cold and wet, threatening livelihoods. In such conditions, climate change can act as a threat multiplier, exacerbating existing tensions and adding to the potential for conflicts.
Hazards resulting from the increasing intensity and frequency of extreme weather events, such as abnormally heavy rainfall, prolonged droughts, desertification, environmental degradation, or sea-level rise and cyclones are already causing an average of more than 20 million people to leave their homes and move to other areas in their countries each year.
