The regeneration of brownfields has been increasingly recognized as a key instrument in sustainable land management, since free developable land (or so called "greenfields") has become a scare and more expensive resource, especially in densely populated areas. However, the complexity of these sites requires considerable efforts to successfully complete their revitalization projects, thus requiring the development and application of appropriate tools to support decision makers in the selection of promising sites where efficiently allocate the limited financial resources. The design of effective prioritization tools is a complex process, which requires the analysis and consideration of critical points of attention (PoAs) which has been identified considering the state of the art in literature, and lessons learned from previous developments of regional brownfield (BF) prioritization processes, frameworks and tools. Accordingly, we identified 5 PoAs, namely 1) Assessing end user needs and orientation discussions, 2) Availability and quality of the data needed for the BF prioritization tool, 3) Communication and stakeholder engagement 4) Drivers of regeneration success, and 5) Financing and application costs. To deepen and collate the most recent knowledge on the topics from scientists and practitioners, we organized a focus group discussion within a special session at the AquaConSoil (ACS) conference 2017, where participants were asked to add their experience and thoughts to the discussion in order to identify the most significant and urgent points of attention in BF prioritization tool design. The result of this assessment is a comprehensive table (Table 2), which can support problem owners, investors, service providers, regulators, public and private land managers, decision makers etc. in the identification of the main aspects (sub-topics) to be considered and their relative influences and in the comprehension of the general patterns and challenges to be faced when dealing with the development of BF prioritization tools.
棕地的再生已日益被视为可持续土地管理的重要手段，因为在人口密集地区，可自由开发的土地（即所谓的“绿地”）已变得稀缺且更为昂贵。然而，这些场地的复杂性要求投入大量精力才能成功完成其复兴项目，因此需要开发和应用适当的工具，以支持决策者在有潜力的场地中进行选择，并有效地分配有限的财政资源。有效的优先级排序工具的设计是一个复杂的过程，需要分析和考虑关键点（PoA），这些关键点是在考虑文献综述中的现有技术以及从以前的区域棕地（BF）优先级排序过程、框架和工具的开发中吸取的经验教训的基础上确定的。因此，我们确定了 5 个 PoA，即 1）评估最终用户的需求和方向讨论，2）BF 优先级排序工具所需数据的可用性和质量，3）沟通和利益相关者的参与，4）再生成功的驱动因素，以及 5）融资和应用成本。为了从科学家和从业者那里深入了解和整理最新的主题知识，我们在 2017 年的 AquaConSoil（ACS）会议上组织了一次专题小组讨论，邀请参与者就讨论内容发表意见和想法，以确定 BF 优先级排序工具设计中最重要和最紧迫的关注点。这项评估的结果是一张综合表格（表 2），可以为问题所有者、投资者、服务提供商、监管机构、公共和私人土地管理者、决策者等提供支持，帮助他们识别需要考虑的主要方面（子主题）及其相对影响，并理解在开发 BF 优先级排序工具时需要面对的总体模式和挑战。
