Joaquim runs restlessly among toys strewn on the floor of a classroom in Canoas, in the Brazilian state of Rio Grande do Sul. But today is not a school day. Joaquim is not a student here. All the desks are stacked to the side to make way for mattresses, turning a classroom into a shelter for people displaced by floods.
This space previously used by students is now occupied by whole families. And there are many of them, housed in makeshift accommodations after torrential rains in April flooded whole cities and left hundreds of thousands of people without shelter.
