There is a great interest in society in making urban districts more sustainable. Sustainable and resource-efficient urban development (SDG 11) is a process that, based on the analysis of the initial situation, leads to the formulation of specific goals and must be planned, accompanied, assessed and managed. Thus, this contribution presents a fundamental, multi-perspective concept to assess and manage the use of (natural) resources (stocks and flows), in particular (1) water (rain, potable and waste water), (2) land use (settlements, traffic area, open/green areas, ecosystems), (3) raw materials (material in- and outputs, recycling and disposal, C&D waste, and fossil fuels) in a defined urban district.

社会对使城市地区更具可持续性有着极大的兴趣。可持续和资源节约型城市发展（SDG 11）是一个基于对初始情况的分析，导致制定具体目标的过程，必须进行规划、伴随、评估和管理。因此，这项贡献提出了一个基本的、多视角的概念来评估和管理（自然）资源（存量和流量）的使用，特别是（1）水（雨水、饮用水和废水），（2）土地使用（住区、交通区域、开放/绿地、生态系统），（3）原材料（材料输入和输出、回收和处置、C&D废物和化石燃料）在特定的市区。
