Future scenarios provide challenging, plausible and relevant stories about how the future could unfold. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenarios published over the period 1997–2011 and within this research, a sub-set of >160 scenarios has been identified (and categorized) based on their narratives according to the structure first proposed by the Global Scenario Group (GSG) in 1997; three world types (Business as Usual, Barbarization, and Great Transitions) and six scenarios, two for each world type (Policy Reform—PR, Market Forces—MF, Breakdown—B, Fortress World—FW, Eco-Communalism—EC and New Sustainability Paradigm—NSP). It is suggested that four of these scenario archetypes (MF, PR, NSP and FW) are sufficiently distinct to facilitate active stakeholder engagement in futures thinking. Moreover they are accompanied by a well-established, internally consistent set of narratives that provide a deeper understanding of the key fundamental drivers (e.g., STEEP—Social, Technological, Economic, Environmental and Political) that could bring about realistic world changes through a push or a pull effect. This is testament to the original concept of the GSG scenarios and their development and refinement over a 16 year period.

Purpose: Designers and planners in the UK are being asked by government to address sustainability. This paper seeks to explore how such issues can be addressed with the urban design process. From the literature, it is unclear when specific sustainability issues should be addressed, who actually makes decisions and what influences them, or how different stakeholders are engaged.Design/methodology/approach: A case study is presented, focusing on the early stages of an urban design and redevelopment process taking place in a deprived region of the UK. Interviews with key decision‐makers and observations were conducted and subsequently analysed using content analysis.Findings: The findings show that the process adopted by clients and consultants was relatively similar to that identified by the literature. The importance of creating a sustainable community, and of addressing deprivation and poor services was recognised from the outset. Sustainability was referred to in the briefing to select a team of consultants to develop a vision and regeneration framework. However, specific problems related to sustainability, such as crime and poor health, were not communicated through the briefing documents, for fear of deterring private investment. Indeed, the need to attract private investment was a key aspect of early stage of the urban design process.Originality/value: This paper highlights potential difficulties of addressing sustainability at the early stage of the design process, when private sector backing is such a crucial component of the regeneration.

Tree planting is widely advocated and applied in urban areas, with large-scale projects underway in cities globally. Numerous potential benefits are used to justify these planting campaigns. However, reports of poor tree survival raise questions about the ability of such projects to deliver on their promises over the long-term. Each potential benefit requires different supporting conditions—relating not only to the type and placement of the tree, but also to the broader urban system within which it is embedded. This set of supporting conditions may not always be mutually compatible and may not persist for the lifetime of the tree. Here, we demonstrate a systems-based approach that makes these dependencies, synergies, and tensions more explicit, allowing them to be used to test the decadal-scale resilience of urban street trees. Our analysis highlights social, environmental, and economic assumptions that are implicit within planting projects; notably that high levels of maintenance and public support for urban street trees will persist throughout their natural lifespan, and that the surrounding built form will remain largely unchanged. Whilst the vulnerability of each benefit may be highly context specific, we identify approaches that address some typical weaknesses, making a functional, resilient, urban forest more attainable.
