New Urban Agenda A/RES/71/256 conceptualization to design, budgeting, implementation, evaluation and review, rooted in new forms of direct partnership between Governments at all levels and civil society, including through broad-based and well-resourced permanent mechanisms and platforms for cooperation and consultation open to all, using information and communications technologies and accessible data solutions. Planning and managing urban spatial development 93. We acknowledge the principles and strategies for urban and territorial planning contained in the International Guidelines on Urban and Territorial Planning, approved by the Governing Council of UN-Habitat in its resolution 25/6 of 23 April 2015. 17 94. We will implement integrated planning that aims to balance short-term needs with the long-term desired outcomes of a competitive economy, high quality of life and sustainable environment. We will also strive to build flexibility into our plans in order to adjust to changing social and economic conditions o ver time. We will implement and systematically evaluate these plans, while making efforts to leverage innovations in technology and to produce a better living environment. 95. We will support the implementation of integrated, polycentric and balanced territorial development policies and plans, encouraging cooperation and mutual support among different scales of cities and human settlements, strengthening the role of small and intermediate cities and towns in enhancing food security and nutrition systems, providing access to sustainable, affordable, adequate, resilient and safe housing, infrastructure and services, facilitating effective trade links across the urban-rural continuum and ensuring that small-scale farmers and fishers are linked to local, subnational, national, regional and global value chains and markets. We will also support urban agriculture and farming, as well as responsible, local and sustainable consumption and production, and social interactions, through enabling and accessible networks of local markets and commerce as an option for contributing to sustainability and food security. 96. We will encourage the implementation of sustainable urban and territorial planning, including city-region and metropolitan plans, to encourage synergies and interactions among urban areas of all sizes and their peri -urban and rural surroundings, including those that are cross-border, and we will support the development of sustainable regional infrastructure projects that stimulate sustainable economic productivity, promoting equitable growth of regions across the urban-rural continuum. In this regard, we will promote urban-rural partnerships and inter-municipal cooperation mechanisms based on functional territories and urban areas as effective instruments for performing municipal and metropolitan administrative tasks, delivering public services and promoting both local and regional development. 97. We will promote planned urban extensions and infill, prioritizing renewal, regeneration and retrofitting of urban areas, as appropriate, including the upgrading of slums and informal settlements, providing high -quality buildings and public spaces, promoting integrated and participatory approaches involving all relevant stakeholders and inhabitants and avoiding spatial and socioeconomic segregation and gentrification, while preserving cultural heritage and preventing and containing urban sprawl. _______________ 17 Ibid., Seventieth Session, Supplement No. 8 (A/70/8), annex. 17/29
