Under international law, certain types of migrants have legal rights, including the right to protection. Others do not, including climate migrants.
What do we mean by protection?
In this instance we mean social protection: access to housing, healthcare, education, protection under the law. There is also the issue of your right to actually live in the city or country where you migrate to - and if you have the right to work and earn a sustainable income.
Most of these issues stem from your right to residency wherever you end up. Have the legal documents allowing you to live and work will make all the difference. Without them, migrants become even more vulnerable and trapped in an existence where choices are limited and options to make changes are few.
