Abstract Background The urban water system is the worst hit in global climate change. Water resilience is the system’s ability to retaliate and recover from various water-related disruptions. The present study aims to delineate the water resilience zones in Chennai city, Tamil Nadu, India, by effectively integrating the geographic information system, remote sensing, and analytical hierarchy process (AHP). Methods The methodology incorporated 15 vital factors. A multi-criteria decision analysis technique was adopted to assign a weight to each parameter using the AHP. A pairwise decision matrix was constructed, parameter’s relative importance and the consistency ratio were established. Integration of all maps by weighted overlay analysis technique depicted water resilience intensities of five different classes. Results Very low, low and moderate water resilience areas accounted for more than three-fourth of the study area. Area Under Curve score (80.12%) depicted the accuracy of the developed model. Sensitivity analysis determined the significance of the parameters in the delineation. The logical structural approach can be employed in other parts of India or elsewhere with modifications. Conclusion This study is novel in its approach by holistically analyzing water resilience by integrating disruptions related to flood, drought and the city's water infrastructure system's adequacy and efficiency. Researchers and planners can effectively use the study results to ensure resilience as a new perspective on effective water resource management and climate change mitigation. It becomes a decision aid mechanism identifying where the system is vulnerable to potential water-related risks for employing resilience measures.

The productive Waqf can be utilized for developing infrastructure in Indonesia as this country has incredible waqf potential. However, the utilization of waqf assets has not been specified for infrastructure development, which has many benefits (maslahah) for Indonesia. This study aims to determine the main problem in utilizing Waqf for infrastructure development in Indonesia from regulatory dimension, management dimension, program dimension, and literacy dimension. The data analysis technique used in this study is Analytical Hierarchy Process (AHP). This study has five experts to deliver their perspective regarding problems and solutions for infrastructure development using productive Waqf in Indonesia. The study results indicate that the severe problem in utilizing productive Waqf for infrastructure in Indonesia based on experts' agreement is the Lack of professional waqf (nazhir) management in managing waqf assets. With increasing the professionalism of nazhir in the management of productive Waqf, the waqf assets are expected to grow gradually that can be used to develop and improve infrastructure in Indonesia. Lastly, the excellent management of Waqf will be able to attract the Muslim community's intention to donate.

Process Method

This study investigates the functions of international tourism hubs, namely, the gathering and distributing function, transferring function, and management and service function. An assessment index of 49 indicators is developed measuring these functions based on the literature review and a survey of expert panel. Analytical hierarchy process method was applied to determine the importance weight of the indicators. Two cities in China, Beijing and Shanghai, were selected to empirically test the assessment index and compared with the tourism hub functions. The results indicate that Beijing has stronger functions on gathering and distributing tourists, as well as management and services, while Shanghai exceeded on transferring function due to its tourist distribution center. Strategic and managerial implications and suggestions are provided based on the study results.

The Impact

This paper assesses the uncertainties in the projected future runoff resulting from climate change and downscaling methods in the Biliu River basin (Liaoning province, Northeast China). One widely used hydrological model SWAT, 11 Global Climate Models (GCMs), two statistical downscaling methods, four dynamical downscaling datasets, and two Representative Concentration Pathways (RCP4.5 and RCP8.5) are applied to construct 22 scenarios to project runoff. Hydrology variables in historical and future periods are compared to investigate their variations, and the uncertainties associated with climate change and downscaling methods are also analyzed. The results show that future temperatures will increase under all scenarios and will increase more under RCP8.5 than RCP4.5, while future precipitation will increase under 16 scenarios. Future runoff tends to decrease under 13 out of the 22 scenarios. We also found that the mean runoff changes ranging from −38.38% to 33.98%. Future monthly runoff increases in May, June, September, and October and decreases in all the other months. Different downscaling methods have little impact on the lower envelope of runoff, and they mainly impact the upper envelope of the runoff. The impact of climate change can be regarded as the main source of the runoff uncertainty during the flood period (from May to September), while the impact of downscaling methods can be regarded as the main source during the non-flood season (from October to April). This study separated the uncertainty impact of different factors, and the results could provide very important information for water resource management.

Climate Change Adaptation Strategies

Global climate action plans risk resulting to climate maladaptation and shocks when prudent measures are inapt. Adaptation strategies require multidisciplinary approach from all sectors with periodic monitoring and evaluation which are carefully planned, locally adaptable and results-oriented. For decades, various governments, development practitioners and international organizations have made concerted efforts in tackling large scale climate events. These stern initiatives forms part of Millennium Sustainable Development Goals (SDGs), specifically SDG 13 meant to combat climate change. The increasing demand for frameworks that effectively monitor and examine the outcomes of these huge investments made by policy-makers across regions have enhanced the evaluation and monitoring of various climate change adaptation strategies. This study sought to assess the effectiveness and sustainability of initiated adaptation strategies. The study used descriptive statistics based on informants’ knowledge and experience to assess the effectiveness of adaptation strategies in Dansoman and compare the results with the case of Nador-Berkane coastal community in north eastern part of Morocco where the “no-regret strategy” concept was adopted. Assessing the effectiveness of strategies is one of the key components of monitoring and evaluation process of climate change and is often overlooked, hence, the need for this study. Results from this study based on the informants’ experience and assessment show that climate change adaptation strategies in the study area are not effective and sustainable. This study serves as a baseline information for relevant stakeholders on critical areas, which ought to be prioritized to reduce the locals’ vulnerability to climate hazards. Assessing the effectiveness of adaptation strategies aid in ensuring efficiency and efficacy of planned and already initiated projects. Further research could be conducted on the cost of adaptation mechanisms and willingness to pay for sea defense systems in the area.

The Impact

Assessment of the degree of meteorological drought in Dak Lak province is carried out using the SPI index and the water balance index K in the period 1985 - 2019. The results show that: According to the SPI index, drought tends to occur more at the time of transition from the dry season to the rainy season, during the rainy season, and from the time of transition from the rainy season to the dry season. The K-index in the period 1985 - 2019 showed there was a dry period at the beginning of the year from January to April. The anomalous drought factor plays a very important role because its large influence can cause damages, and allows assessing the variability of rainfall and the impact of climate change on the region. The study and evaluation of meteorological drought have practical significance, supporting managers in making policies on water resource management, ensuring sustainable economic and social development in the context of global climate change.

Adaptation Options

Given the multidimensional nature of climate change issues, decision-making in climate change adaptation is a complex process, and suitable decision support methods are needed. The aim of this paper was to rank saltwater intrusion adaptation options for farmers in two provinces in the central coastal region of Vietnam using the analytical hierarchy process method. Data for the analysis were obtained through a literature review, field observations, and face-to-face interviews and focus group discussions with key informants. We combined two ways of weighting to arrive at final scores for each of the identified adaptation options: prioritizing criteria and subcriteria by pairwise comparison and rating the different alternatives with respect to the lowest level subcriteria. In doing so, we also investigated differences in the priority sets and final rankings of the analytical hierarchy process applications in both provinces. In our study, we worked with group consensus scores on both the criteria weights and the ratings for the different adaptation options for each of the criteria. Our results revealed that “sustainability and equity” was the most important criteria, while coherence ranked lowest. The final ranking of adaptation options differed between both provinces due to differences in the geographical and socioeconomic characteristics of the study areas. The consistency ratios for all pairwise matrices were less than 0.1, indicating that judgments from the focus group discussions with respect to the different criteria were highly consistent. A sensitivity analysis of our results confirmed the robustness of the rankings in our research.
