A/RES/71/256 New Urban Agenda 98. We will promote integrated urban and territorial planning, including planned urban extensions based on the principles of equitable, efficient and sustainable use of land and natural resources, compactness, polycentrism, appropriate density and connectivity, and multiple use of space, as well as mixed social and economic uses in built-up areas, in order to prevent urban sprawl, reduce mobility challenges and needs and service delivery costs per capita and harness density and economies of scale and agglomeration, as appropriate. 99. We will support the implementation of urban planning strategies, as appropriate, that facilitate a social mix through the provision of affordable housing options with access to quality basic services and public spaces for all, enhancing safety and security and favouring social and intergenerational interaction and the appreciation of diversity. We will take steps to include appropriate training and support for service delivery professionals and communities in areas affected by urban violence. 100. We will support the provision of well-designed networks of safe, accessible, green and quality streets and other public spaces that are accessible to all and free from crime and violence, including sexual harassment and gender -based violence, considering the human scale, and measures that allow for the best possible commercial use of street-level floors, fostering both formal and informal local markets and commerce, as well as not-for-profit community initiatives, bringing people into public spaces and promoting walkability and cycling with the goal of improving health and well-being. 101. We will integrate disaster risk reduction and climate change adaptation and mitigation considerations and measures into age- and gender-responsive urban and territorial development and planning processes, including greenhouse gas emissions, resilience-based and climate-effective design of spaces, buildings and construction, services and infrastructure, and nature-based solutions. We will promote cooperation and coordination across sectors and build the capacities of local authorities to develop and implement disaster risk reduction and response plans, such as risk assessments concerning the location of current and future public facilities, and to formulate adequate contingency and evacuation procedures. 102. We will strive to improve capacity for urban planning and design and the provision of training for urban planners at the national, subnational and local levels. 103. We will integrate inclusive measures for urban safety and the prevention of crime and violence, including terrorism and violent extremism conducive to terrorism. Such measures will, where appropriate, engage relevant local communities and non-governmental actors in developing urban strategies and initiatives, including taking into account slums and informal settlements as well as vulnerability and cultural factors in the development of policies concerning public security and crime and violence prevention, including by preventing and countering the stigmatization of specific groups as posing inherently greater security threats. 104. We will promote compliance with legal requirements through strong, inclusive management frameworks and accountable institutions that deal with land registration and governance, applying transparent and sustainable management and use of land, property registration and sound financial systems. We will support local governments and relevant stakeholders, through a variety of mechanisms, in developing and using basic land inventory information, such as cadastres, valuation and risk maps, and land and housing price records, to generate the high-quality, timely and reliable data — disaggregated by income, sex, age, race, ethnicity, migration status, disability, geographic location and other characteristics relevant in 18/29
