We will foster the progressive realization of the right to adequate housing as a component of the right to an adequate standard of living. We will develop and implement housing policies at all levels, incorporating participatory planning and applying the principle of subsidiarity, as appropriate, in order to ensure coherence among national, subnational and local development strategies, land policies and housing supply. 106. We will promote housing policies based on the principles of social inclusion, economic effectiveness and environmental protection. We will support the effective use of public resources for affordable and sustainable housing, including land in central and consolidated areas of cities with adequate infrastructure, and encourage mixed-income development to promote social inclusion and cohesion. 107. We will encourage the development of policies, tools, mechanisms and financing models that promote access to a wide range of affordable, sustainable housing options, including rental and other tenure options, as well as cooperative solutions such as co-housing, community land trusts and other forms of collective tenure that would address the evolving needs of per sons and communities, in order to improve the supply of housing (especially for low-income groups), prevent segregation and arbitrary forced evictions and displacements and provide dignified and adequate reallocation. This will include support to increment al housing and selfbuild schemes, with special attention to programmes for upgrading slums and informal settlements. 108. We will support the development of housing policies that foster local integrated housing approaches by addressing the strong links b etween education, employment, housing and health, preventing exclusion and segregation.

We will consider increased allocations of financial and human resources, as appropriate, for the upgrading and, to the extent possible, prevention of slums and informal settlements, with strategies that go beyond physical and environmental improvements to ensure that slums and informal settlements are integrated into the social, economic, cultural and political dimensions of cities. These strategies should include, as applicable, access to sustainable, adequate, safe and affordable housing, basic and social services, and safe, inclusive, accessible, green and quality public spaces, and they should promote security of tenure and its regularization, as well as measures for conflict prevention and mediation. 110. We will support efforts to define and reinforce inclusive and transparent monitoring systems for reducing the proportion of people living in slums and informal settlements, taking into account the exper iences gained from previous efforts to improve the living conditions of slum and informal -settlement dwellers. 111. We will promote the development of adequate and enforceable regulations in the housing sector, including, as applicable, resilient building codes, standards, development permits, land-use by-laws and ordinances, and planning regulations, combating and preventing speculation, displacement, homelessness and arbitrary forced evictions and ensuring sustainability, quality, affordability, health, safety, accessibility, energy and resource efficiency, and resilience.
