The guest of this episode, Federico Batista Poitier, studied first forensic anthropology and then human rights. After graduating from the European Master in Human Rights and Democratisation, he specialised in issues related to accessibility and the implementation of the UN Convention of the Rights of Persons with Disabilities. Federico started working on issues related to disability when he was an English teacher in South Korea and worked in an inclusive school.

He currently works as accessibility policy officer for United Cities and Local Governments (UCLG), that he describes as a kind of UN of local and regional governments. 65 % of the Sustainable Development Goals need implementation at the local level to be realised by 2030. He particularly focuses on accessibility as mandated through the international human rights framework of the Convention on the Rights of Persons with Disability and its article 9, a lot of the competency to implement this article being with local governments. This implementation is sometimes made difficult with coordination and centralisation.
