Abstract

ABSTRACT Assessments of urban green drainage infrastructure (UGDI) have always been a headache in contemporary times which is a roadblock to enticing investors. This study prioritized the underlying sustainability indicators of UGDI systems in Ghana. After an exhaustive literature review, some identified sustainability indicators were compounded into semi-structured questionnaires. Sixty-two built environment professionals were asked to rate the significance of each indicator. A parametric test was used to prioritize the indicators. The results indicated that the most significant underlying sustainability indicators were; ‘Flood control’, ‘Compliance with sustainable development goals’, ‘multi-functionality’, ‘energy efficiency and GHG emissions’ and ‘Initial Construction Cost’. To understand how UGDI performs with regards to flood and pollution mitigation, specific geographical performance indicators are required. This is an under-explored area in the Ghanaian context. Hence, the indicators espoused in this study serve as a starting point for the development of appropriate frameworks to aid the implementation of UGDI.

城市绿色排水基础设施系统关键潜在可持续性指标的优先顺序

摘要城市绿色排水基础设施(UGDI)的评估一直是当代令人头疼的问题，也是吸引投资者的一个障碍。本研究对加纳UGDI系统的潜在可持续性指标进行了优先排序。在详尽的文献回顾之后，一些确定的可持续性指标被合并成半结构化的问卷。62位建筑环境专业人士被要求对每个指标的重要性进行评级。采用参数检验对指标进行排序。结果表明，最显著的潜在可持续性指标是;“防洪”、“符合可持续发展目标”、“多功能”、“能源效率和温室气体排放”以及“初始建设成本”。要了解政府教育发展计划在减轻洪水和污染方面的表现，需要具体的地理表现指标。在加纳的背景下，这是一个未被开发的领域。因此，本研究中采用的指标可作为制定适当框架的起点，以帮助实施政府间发展指标。

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
