Unprecedented challenges in urban management of water, waste and climate change-amplified by urbanisation and economic growth-are growing in Asia. In this circumstance, cities need to be aware of threats and opportunities to improve their capacity in addressing these challenges. This paper identifies priorities, barriers and enablers of these capacities. Through the City Blueprint Approach-an integrated baseline assessment of the urban water cycle-11 Asian cities are assessed. Three cities are selected for an in-depth governance capacity analysis of their challenges with a focus on floods. Solid waste collection and treatment and access to improved drinking water and sanitation can be considered priorities, especially in cities with considerable slum populations. These people are also disproportionately affected by the impacts of climate-related hazards. The high variation of water management performance among Asian cities shows high potential for city-to-city learning by sharing best practices in water technology and governance. Combining interventions, i.e., by exploring co-benefits with other sectors (e.g., transport and energy) will increase efficiency, improve resilience, and lower the cost. Although governance capacities varied among cities, management of available information, monitoring and evaluation showed to be reoccurring points for improvement. Cities are also expected to increase implementation capacities using better policy, stricter compliance and preparedness next to promoting community involvement. Consequently, the city transformation process can be more concrete, efficient and inclusive.
亚洲城市在水、废物和气候变化的城市管理上面临前所未有的挑战,这些挑战因城市化和经济增长而加剧。在这种情况下,城市需要意识到这些挑战所带来的威胁和机遇,以提高其应对这些挑战的能力。本文确定了这些能力的优先事项、障碍和推动因素。通过城市蓝图方法——对城市水循环进行综合基准评估——对 11 个亚洲城市进行了评估。选择了三个城市对其面临的挑战进行深入的治理能力分析,重点关注洪水问题。固体废物收集和处理以及获得更好的饮用水和卫生设施可以被视为优先事项,特别是在人口众多的贫民窟城市。这些人也不成比例地受到与气候相关的灾害的影响。亚洲城市之间的水资源管理绩效差异很大,表明通过分享水技术和治理方面的最佳实践,城市之间具有很高的学习潜力。结合干预措施,即通过与其他部门(如交通和能源)探索共同效益,将提高效率、增强弹性并降低成本。尽管城市之间的治理能力存在差异,但可用信息的管理、监测和评估显示出需要不断改进的地方。城市还预计将通过更好的政策、更严格的合规性和准备工作来提高实施能力,同时促进社区参与。因此,城市转型过程可以更加具体、高效和包容。
