Aim. The aim of the paper is to reflect on role of urban wastelands in context of legal and social construction of urban public spaces. This reflexion is based on analysis of what ecological values are connected with urban wastelands and how those values manifested during pandemic. Methods. Paper is based on observatory research put in the context of theoretical reflection on urban research, especially applying to ecology and urban management. Results. Spontaneous social animation of urban wastelands related to restrictions placed upon using green areas by Polish government in order to stop the spread of COVID-19 in April 2020 revealed potential of such places to trace regulations introduced in public spaces resulting in transfer of some social practices to less ordered and supervised areas. Conclusions. Nowadays urban wastelands gained appreciation as areas of specific high biodiversity and ecological value. However they can also be useful as a measure of social practices excluded from planned and highly organised urban places. They can be used to trace them and rethink legal and social circumstances that led to that exclusion.

什么浪费？

目标。本文的目的是在城市公共空间的法律和社会建设背景下反思城市荒地的作用。这种反思基于对哪些生态价值与城市荒地相关以及这些价值在大流行期间如何表现的分析。方法。本文是基于天文台研究，在理论上对城市研究进行反思的背景下，尤其是在生态学和城市管理方面。结果。波兰政府为阻止2020年4月COVID-19的传播而限制使用绿地的措施，对城市荒地产生了自发的社会动荡，这表明这些地方有可能追踪公共场所引入的法规，从而导致一些社会行为向秩序井然和监督较少的地区。结论。如今，城市荒地已成为具有特别高的生物多样性和生态价值的地区。但是，它们也可以用作衡量计划中和高度组织化的城市场所之外的社会实践的一种方法。它们可以用来追踪它们，并重新考虑导致这种排斥的法律和社会环境。
