Abstract Urbanization has been the main driving force for China's economic growth in recent years; however, the highly concentrated urbanized lifestyle has brought many environmental problems to residents, the most urgent of which is urban stormwater management. Some countries have proposed plans for urban stormwater management, such as Low Impact Development (LID), Water Sensitive Urban Design (WSUD), Sustainable Urban Drainage Systems (SUDS). As a country with relatively underdeveloped urban stormwater management, China's government proposed an ambitious urban stormwater management plan in 2014, called the Sponge City Programme, which means that a city is designed to act like a sponge, with good ‘resilience’ in adapting to environmental changes and coping with natural disasters. As of 2021, this programme has led to SCP projects in 30 pilot districts all over China, the Sponge City Programme construction impacts both urban development and resident's life. However, there are risks and challenges associated with these projects. Using government research documents as a framework, this paper carefully reviews the progress of the Sponge City Programme in recent years and shows the main challenges faced by Sponge City Programme in terms of connotation, investment, and technology. On this basis, the paper puts forward practical suggestions for the development of the Sponge City Programme and details potential opportunities of new technology, ideology, planning, and flexible investment.

<p>‘<em>Sponge City Program</em>’ (SCP) is the term used to describe the Chinese government’s approach to urban surface water management. The concept was conceived in 2014 in response to an increasing incidence of urban surface flooding in many Chinese cities. While ambitious and far-reaching in its aim (of reducing national flood risk, increasing water supply and improving water quality), the initiative must be implemented by individual sub-provincial or municipal-level government entities. The concept is similar to <em>Blue-Green Cities</em> (BGCs); <em>sustainable drainage systems</em> (SuDS) in the UK, it is developing with different regional climatic and hydrological characteristics, considering rapid urbanization. Indeed, the increasing use of national rather than international examples of best practice reflects a growing body of knowledge that has evolved since the start of the Sponge City initiative. The SCP so far now has run through 6 years and experience a transition on urban stormwater management and planning practices. In this paper, the implementation of the latest SCP guidelines will be presented that using the case of Ningbo and other Chinese cities to illustrate the transformation of the current SCP practices that undertaking the consideration of climate, environmental and socio-economic factors, and how the practice tackle challenges on governance, project financing, integration and assessment by the authorities and stakeholders. These valuable experiences will be vitally important influencing future urban stormwater management and planning practices in Chinese cities.</p>

Abstract: The Severity as well as the frequency of short-duration, but damaging, urban area floods have increased in recent years across the world. Alteration to the urban micro-climate due to global climate change impacts may also exacerbate the situation in the near future. The events of floods have increased in Srinagar city as well over the past decades. Sustainable urban stormwater management using low impact development (LID) techniques, along with conventional urban stormwater management systems, can be implemented to mitigate climate-change-induced flood impacts in Srinagar. In this study, the supposed effectiveness of LIDs in the mitigation of urban flood in Srinagar city is analysed keeping in view their limitations at the same time. A critical research on the success of these techniques in urban flood mitigation planning in Srinagar city is also recommended. On summarising different LID approaches in the world, the results revealed that LIDs can be an efficient method for mitigating urban flood impacts. Most of the LID devices developed so far, however, are found to be effective only for small flood peaks. The major challenges include identification of the best LID practices for the region of interest, efficiency improvements in technical areas, and site-specific optimization of LID parameters. Research and improvements in these areas will allow better mitigation of climate-change-induced urban floods in a cost-effective manner and will also assist in the achievement of sustainable development goals for Srinagar city and will help us to tackle the increasing problems of water logging and floods in the summer capital of Jammu and Kashmir.
