AbstractA major challenge for researchers and urban planning practitioners is how to obtain meaningful and influential contributions on urban and environmental planning activities from children and young people within the constraints of adult policy and practice. The key elements of this challenge concern traditional methods of communication between ‘experts’ and children and young people in rationalist planning settings, versus emerging research in relation to children's and young people's views and agency around civic participation. This article will address the work of a number of researchers and practitioners who have grappled with the inherent tenions of making planning practice and urban design more inclusionary, while facilitating and respecting children and young people's civic participation. This article also advocates the advantages and strengths of their participation in planning and urban design processes.With a focus on two exploratory programs developed by the authors in the Australian states of New South Wales and Victoria, this article will demonstrate how the sharing of knowledge and skills between planning and design professionals and children and young people can lead to more meaningful and influential contributions from them. The programs examined were informed by leading practice both in Australia and internationally, and have assisted to develop children and young people's sense of spatial competence, and their confidence and efficacy in their local environment, contributing ultimately to their wellbeing. They have also supported the establishment of youth leadership groups with the confidence and skills to contribute to ongoing local government urban and environmental planning activities.

<p><strong>Abstract.</strong> Precise and comprehensive knowledge about 3D urban space is required for simulation and analysis in the fields of urban and environmental planning, city administration and disaster management. In order to facilitate these applications, geo-information about functional, semantic, and topographic aspects of urban features, their mutual dependencies and relations is needed. Substantial work has been done in the modelling and representation of above-ground features in the context of 3D city modelling. However, the belowground part of the real world, of which utility networks form a big part, is often neglected. Existing data models for utility networks are generally very domain-specific and, therefore, not suitable either. This paper describes a 3D data modelling approach for integrated management of below-ground utility networks and related above-ground city objects. This approach consists of manipulating first the structure of existing utility data in the commonly used Feature Manipulation Engine ETL software in order to make the data compliant to the CityGML Utility Network ADE data model. Subsequently, workspaces are created that take care of storing the CityGML data into the free and open-source 3D City Database, which has been extended in order to manage utility network data, too. Moreover, the research shows the suitability of the extended 3DCityDB to perform graph-based topological operations by means of the PostgreSQL pgRouting extension. Lastly, the results are visualized in typical GIS applications, e.g. QGIS and ArcGIS.</p>

The Caracas Metropolitan Strategic Plan 2020 (CMSP2020) is an instance of urban and environmental planning that seeks to construct a collective ‘city pact’ for Caracas, currently among the most troubled and violent cities in Latin America. Its main idea is to recover the city through the rescue of its public spaces, by centering on six strategic axes for transforming Caracas: accessibility and mobility; public safety, public spaces and housing improvement; environmental sustainability; productivity and entrepreneurship; governability; and the development of a constructive and responsible citizenship. This model, partly inspired by Medellin’s Library Parks, may be useful for other large cities in the region that suffer similar socio-political fractures, as well as accessibility, mobility, environmental, productive, governance and safety issues.

The crisis management of a disaster, whether caused naturally or by human action, requires a thorough knowledge of the territory involved, with regard to both its terrain and its developed areas.<br><br> Therefore, it is essential that the National Mapping and Cadastral Agencies (NMCAs) and all other public and scientific institutions responsible for the production of geospatial information closely co-operate in making their data in that field available. This crucial sharing of geographic information is a top-level priority, not only in a disaster emergency situation, but also for effective urban and environmental planning and Cultural Heritage protection and preservation.<br><br> Geospatial data-sharing, responding to the needs of all institutions involved in disaster surveying operations, is fundamental, as a priority, to the task of avoiding loss of human lives. However, no less important is the acquisition, dissemination and use of this data, in addition to direct, “in-the-field” operations of specialists in geomatics, in order to preserve the Cultural Heritage located in the crisis area. It is in this context that an NMCA such as the Italian Military Geographic Institute (IGMI) plays a key role.
