“…Green measures including green roofs, trees, low vegetation, and unsealing provide numerous additional benefits beyond those of white measures. The benefits were quantified as urban ecosystem services (Bolund and Hunhammer, 1999) using the methodology outlined in Johnson and Geisendorf (2019).…”

“…There have been examples of monetary evaluation of these types of benefits appearing in the literature (see e.g., Dehnhardt, 2014), but CBAs of UHI adaptation scenarios are still rare. An exception is the recent study by Johnson and Geisendorf (2019), who evaluated the financial viability of sustainable urban drainage systems (SUDS) for a neighborhood in Berlin.…”

“…To fill the gap in this area, the aim of this paper is to undertake a cost benefit analysis of adaptation scenarios produced using an urban climate model applied to smaller cities in Austria, i.e., Mödling, Klagenfurt and Salzburg, with populations of around 20,000, 100,000 and 150,000, respectively. The methodology applied here draws upon the work of Johnson and Geisendorf (2019) but scales this upward from a neighborhood to a city level. Costs are calculated for each scenario and compared with monetary valuations of a range of benefits including reductions in heat-related mortality, morbidity, and productivity loss, along with an extensive set of urban ecosystem service benefits to calculate the net present value, the benefit-cost ratio, and the benefit and cost efficiencies.…”

Urban heat islands are an increasing concern even in small- to medium-sized cities, although these areas are still understudied especially in terms of the economic feasibility of adaptation options. This paper uses adaptation scenarios produced by an urban climate model as inputs to a social cost–benefit analysis in three small- to medium-sized cities in Austria: Mödling, Klagenfurt, and Salzburg. The adaptation scenarios, which consider measures such as increasing the reflectivity of different sealed surfaces (referred to as the White City scenario) as well as greening measures (i.e. the Green City scenario), show decreases in the number of hot days (Tmax ≥30°C) when implemented. Benefits include reductions in heat-related mortality, which are modeled based on trends of daily mortality and climate data, reduced morbidity, productivity loss, and numerous urban ecosystem services. The results demonstrate favorable benefit–cost ratios of a combination of measures (White and Green City) of 1.27, 1.36, and 2.68 for Mödling, Klagenfurt, and Salzburg, respectively, indicating positive economic grounds for supporting policies in line with the adaptation scenarios. Furthermore, results of the Green City vs. White City showed higher benefits for the combined and Green City scenarios despite higher costs for each of the cities.

“…Scenarios that include monitoring and alert systems cost approximately 11 USD.inhab −1 .m −2 , while systems that do not have monitoring and alert systems based on reconstruction after natural disasters cost an average of 19 USD.inhab −1 .m −2 . In addition, NBS can be installed primarily in vulnerable locations, with multiscale coverage to integrate stakeholders and associated costs [87,88]. Thus, further studies with real-time controlled NBS must be conducted in order to assess the economic and social benefits that hydrological, water quality and monitoring can generate for urban environments.…”

Nature-based solutions (NBS) as green infrastructures to urban drainage are an effective mitigation strategy both in terms of quantity and quality of runoff. Real-time control (RTC) can complement both flood mitigation and improvement of water quality by controlling elements of the drainage and sewage system. This study assessed the improvement opportunities with RTC of three NBS-related techniques commonly applied in urban drainage with different spatial scales: green roof, bioretention and detention basin and the remaining challenges to integrate both methods. Additionally, our investigations showed that the main difficulties reported involve the planning and monitoring stages of the RTC system. All of the studied devices can benefit from RTC. It is possible to observe that, despite the good results reported in the literature, the application of RTC to NBS studies on urban drainage are very recent. There are several opportunities that can be explored to optimize the performance.

“…At present, flood control dispatching is mainly considered from the perspective of hydrology, without considering the impact of flood control on economy, society, and environment [43][44][45]. From the perspective of management, a decision support system based on watersheds can be combined with a socio-economic analysis to conduct flood control operation [46].…”

Research on the Allocation of Flood Drainage Rights of the Sunan Canal Based on a Bi-level Multi-Objective Programming Model

To reduce flood disasters and optimize of the comprehensive benefit of the water basin, the allocation of regional flood drainage rights is of great significance. Using the “top-down” allocation mode, we consider the influence of the social, economic, and ecological environments, flood drainage demand and efficiency, and other factors on the allocation of flood drainage rights. A bi-level multi-objective programming model from the perspective of fairness and efficiency is established for the allocation. The Sunan Canal is taken as a typical case study. The model is solved by the multi-objective optimal allocation method and the master–slave hierarchical interactive iteration algorithm. After three iterations of the initial solution, the allocation of flood drainage rights in six flood control regions finally reach an effective state. The results of the model were compared with results based on historical allocation principles, showing that the bi-level multi-objective programming model, based on the principles of fairness and efficiency, is more in line with the current social and economic development of the canal. In view of the institutional background of water resources management in China and the flood drainage pressure faced by various regions, the allocation of flood drainage rights should be comprehensively considered in combination with various factors, and the market mechanism should be utilized to optimize the allocation.
