预计城市地区在21世纪将继续迅速增长。在全球范围内，城市是温室气体排放的主要来源，其高人口密度使其成为易受全球环境变化影响的潜在焦点。此外，就物资和资源流动而言，它们的影响力远远超出其边界。显然，将城市系统视为在稳定环境中建造的静态人工制品，或继续将其与影响城市内许多气候和社会经济变化的全球背景相分离，已不再站得住脚。此外，未来气候和社会经济条件的不确定性给规划者带来了重大挑战。提出了一个框架，用于分析城市系统的证据为基础的工具，在较长的时间尺度。这构成了这一关键主题领域未来挑战和研究方向宣言的基础，最终将帮助工程师和城市规划师更好地了解他们所负责的领域，并制定适应战略，以应对长期全球变化带来的挑战，并导致更可持续的城市。
Urban areas are expected to continue their rapid growth in the twenty-first century. Globally, cities are major sources of greenhouse gases emissions and their high population densities make them potential focal points of vulnerability to global environmental change. Moreover, their reach, in terms of flows of materials and resources, extends far outside their borders. Evidently, it is no longer tenable to consider urban systems to be static artefacts constructed in a stable environment, nor continue to divorce them from the global context that influences many of the climatic and socioeconomic changes within cities. Furthermore, the uncertainty in the future climatic and socio-economic conditions poses significant challenges for planners. A framework is proposed for analysing urban systems with evidence-based tools over extended time scales. This forms the basis of a manifesto for future challenges and research directions for this critical subject area, which ultimately will help engineers and urban planners to better understand the areas for which they are responsible and to develop adaptation strategies that can tackle the challenges posed by long-term global change and lead to more sustainable cities.
