Between 22 and 26 March 2010, Rio de Janeiro (Brazil) hosted the 5 World Urban Forum (WUF), an event that has been organised by the United Nations Habitat programme every two years since 2002. After Nairobi (2002), Barcelona (2004), Vancouver (2006) and Beijing (2008), this year´s WUF was based around "The right to the city: bridging the urban divide".
The CSIPD, and the "Human Rights and Local Governments" International Permanent Secretariat of Nantes-Pays de la Loire (SPIDH) organised a debate session on 24 March on "Local governments promoting the right to the city". The panel included representatives of local governments from Brazil, France and Spain, from the United Nations (UNESCO) and civil society organisations (HIC and COHRE). Two CSIPD member cities also participated in a session organised by UNESCO and UN HABITAT on "Inclusive cities for all: UNESCO, UN HABITAT and UCLG joint efforts". This activity took place on 23 March.
Other UCLG committees (Peripheral cities and Urban Strategic Planning) and networks such as the FAL and the IOPD also organised activities on the occasion of the 5 WUF.
