Human mobility

Hotter days and higher flood risk are prompting people across the South to reconsider where they live.

These brief displays frameworks, processes and guidance relevant to planned relocation that exist at the global, regional and national level, offering an overview of the Platform on Disaster Displacement's engagement on planned relocation from 2016-2024.

Each year the climate negotiations attempt to deal with the human cost of climate change – in particular climate-driven displacement. While recent talks have acknowledged the issue, concrete action remains elusive.

This policy brief emphasizes the need for COP decision-makers to prioritize displacement in loss and damage discussions, as it is one of the most significant yet underreported forms of climate impact.

The report warns that climate change intensifies risks for over 120 million displaced people, most in heavily climate-impacted countries. Urgent action is needed to invest in resilience, include their voices, protect them legally, and reduce emissions.

75 percent of 120 million displaced live in climate-impacted countries, where receive only $2 per person in adaptation funding. They face compounded threats from conflict and climate change without adequate support, urging increased climate finance.

Natural hazards drive U.S. migration, with hurricanes, floods, and storms causing significant outflows to nearby counties, potentially increasing future disaster risk for these populations. Tailored policies are needed for specific hazard responses.

This study assesses risk of future coastal flooding before and after moving, for three dates and three emissions scenarios, for 17 communities from a global dataset.
