A/HRC/34/51/Add.2 violence, persons with disabilities, children, young people and all those who are poor or who belong to the “new poor”; (b) Commit to ending homelessness as a priority, in keeping with the Sustainable Development Goals, to leave no-one behind and to ensure adequate, safe and affordable housing and basic services for all, and the New Urban Agenda;27 to this end, they should ensure that the lessons learned from the first national strategy on homelessness are taken on board in a new strategy, including by ensuring a participatory process for its development, and ample consultations with specific municipalities that engaged in implementing the strategy; and ensure that the new strategy encourages preventive measures, not just crisis intervention; (c) Assess and address housing conditions in all informal settlements on an urgent and priority basis, including for Roma communities and communities of people of African descent, in keeping with the goals outlined in the national housing strategy; (d) Prevent demolitions and evictions that result in homelessness. Children should not be removed from their parents for lack of adequate housing. Plans for disadvantaged communities should be developed and implemented in consultation with the populations affected, and should include key human rights principles, such as security of tenure, in situ relocation, access to basic services, including water, sanitation and electricity, affordability, and dignified living conditions. 87. The Government should work closely with the Municipality of Porto and the residents of the ilhas to ensure all those residing in them are provided with adequate accommodation, whether through refurbishment or relocation to affordable long-term housing, and allocate sufficient financial resources to that end. 88. Central, municipal and autonomous regional governments should develop a common vision for cities in Portugal with a view to ensuring they are places of inclusion rather than predominantly for the affluent or tourists, and to ensure the effective implementation of the rights to adequate housing and to non-discrimination for long-term residents as a priority. Better coordination between levels of government, including adequate flow of resources, must be achieved. 89. Governments should adopt new regulatory mechanisms to prevent displacement through “touristification”. They should examine effective policies and practices in other cities around the world facing similar situations with a view to protecting individuals from the negative impact of this phenomenon and of property speculation. 90. The Special Rapporteur recommends that the national and regional authorities moreover: (a) Review eviction procedures, including administrative measures recently adopted, to ensure that they adequately protect the rights of tenants, particularly not to be evicted into homelessness, and ensure that they have access to legal aid or other legal support to challenge evictions in court; (b) Conduct an assessment of the actual need for social housing, subsidized housing and/or rent-controlled housing throughout the country; The Government should then ensure the supply of affordable housing (defined in terms of cost burden relative to income, not in terms of market value) for those with the lowest incomes and those on waiting lists. 27 General Assembly resolution 71/256, annex. 19
