What Is the Role of the UN in Managing Future Migration?

I see this essentially as a temporary adaptation and management of the severe crisis that we are facing. I think there should be finances involved from countries of origin and host countries to make this work as well as possible. And my dream is that over this century, while we do have this large number of people migrating, we are also undertaking that essential work in restoring the planet. So restoring nature, absolutely changing and adapting and transforming our energy systems, our food systems, our infrastructure,. so that by the end of the century, places that were unlivable become livable again.
