João Pereira de Araúj, of Rio Branco, Brazil, stands in floodwater up to his neck, 14 March 2015. &#39;I have seen many floods in my life, but never this high. My home is built on stilts, but now the lower floor is submerged. I look out of the window and see street after street under water &#8211; so many homes and shops. All we can do is wait for the water to go down, clean up and continue.&#39; Photo: Gideon Mendel
