Climate change can affect movement through disasters, livelihoods, health and habitability. This makes cities prepare for new arrivals depend on land use, weather and the infrastructure that stores and moves the resource.

The deeper explanation
The answer in detail
How should cities prepare for new arrivals? is shaped by the forces, choices and constraints described in this collection. Resources, rights, services and planning determine whether movement becomes safer adaptation or deeper vulnerability.
Why it matters
Climate-related mobility connects environmental risk with housing, work, infrastructure, borders and social protection.
The wider system behind cities prepare for new arrivals
Farms, cities, households and ecosystems draw on the same resource, so decisions about cities prepare for new arrivals redistribute access, prices and risk between users.
Insurance, public budgets and trade carry the effects beyond the immediate place: a local shortage or adaptation choice can change food prices, health costs and investment elsewhere.
System lens
What makes this more complicated?
Three layers that help explain what changes the outcome.
Starting conditions
History, resources and institutional capacity set the starting position before the visible outcome appears.
Limits and trade-offs
Rules, capacity and competing priorities limit which responses are practical, even when several options look possible.
Choices and distribution
The outcome depends on who can change those conditions and how its consequences are shared.

Read the main storyMeet the players
Climate change significantly influences migration patterns globally.
organization
Intergovernmental Panel on Climate Change (IPCC)
Research and assessment of climate impacts
Wants toto provide comprehensive assessments of climate change impacts and adaptation strategies.
LeverageInfluences international climate policy and adaptation strategies.
Read profile: Intergovernmental Panel on Climate Change (IPCC)
The IPCC conducts assessments that inform global understanding of climate change, including its effects on migration. Their reports highlight how climate hazards influence movement through disasters and livelihood changes, shaping policy responses worldwide. By providing scientific data, the IPCC helps governments and organizations prepare for climate-related mobility.
organization
International Organization for Migration (IOM)
Facilitating migration management
Wants toto promote humane and orderly migration through effective governance.
LeverageProvides expertise and resources for managing climate migration.
Read profile: International Organization for Migration (IOM)
The IOM addresses the challenges of climate-related migration by providing guidance and support to countries managing internal and cross-border movements. Their work focuses on integrating migration into climate adaptation strategies, ensuring that displaced populations receive necessary resources and support.
organization
World Bank
Funding and research on climate impacts
Wants toto reduce poverty and support sustainable development through financial and technical assistance.
LeverageOffers financial resources and policy advice to mitigate climate impacts.
Read profile: World Bank
The World Bank conducts research on climate migration, focusing on how climate change affects livelihoods and displacement. Their reports, such as 'Groundswell', outline the economic implications of climate-related mobility and provide recommendations for policy interventions to support affected populations.
government
City of New Orleans
Implementing adaptation strategies for climate migration
Wants toto prepare for and manage the impacts of climate migration within the city.
LeverageDirectly influences local adaptation strategies and resource allocation.
Read profile: City of New Orleans
The City of New Orleans develops policies and infrastructure to support new arrivals affected by climate change. They assess local resources, rights, and services to ensure that migration leads to safer adaptation rather than increased vulnerability, particularly in the context of rising sea levels and extreme weather events.
group
Affected Households
Responding to climate pressures
Wants toto seek safer living conditions and livelihoods in response to climate change.
LeverageTheir migration choices shape local demographics and community dynamics.
Read profile: Affected Households
Households affected by climate change often face pressures that compel them to migrate. Their decisions are influenced by local economic and social factors, as well as the availability of resources and services. Understanding their experiences is essential for developing effective adaptation strategies.
