Environmental migration like all types of migration is a gender process. So each migrants will narrabilites, priorities and contributions are influenced by their gender. Sex and gender desegregation often use the synonyms, but they are not, and this has important consequences. Sex desegregation refers to biological sex, and it is what we find, for instance, in national identity documents. And we often see male, female and usually a third designation such as OT or X. For instance, if we enter a country, we often see those on immigration forms. Gender refers to a person gender identity, so it requires migrants to self-identify. And this is very important for migration environmental climate change, because a lot of work that is been done in this space is done through household surveys, for instance. And so gender is something that respondents should indicate. We need to also go beyond desegregation and make sure that a gender perspective is integrated at all stages of migration data work, from the design of data collections, methodologies, all the way to data analysis and publication of data.
