“…The temperature increases 0.6-1.9 • C in winter and spring, 0.5-1.8 • C in summer, and 0.5-1.5 • C in fall. The finding is in good agreement with Peng et al [86]. The number of potential debris stream affected area sites accounts for approximately 9% of the total number of sites (Table 4).…”

The study uses 30 years of the third generation of Advanced Very-High-Resolution Radiometer (AVHRR) NDVI3g monthly data from 1982 to 2012 to identify the natural clusters and important driving factors of the upstream watersheds in Taiwan through hierarchical cluster analysis (HCA) and redundancy analysis (RDA), respectively. Subsequently, as a result of HCA, six clusters were identified based on the 30 years of monthly NDVI data, delineating unique NDVI characteristics of the upstream watersheds. Additionally, based on the RDA results, environmental factors, including precipitation, temperature, slope, and aspect, can explain approximately 52% of the NDVI variance over the entire time series. Among environmental factors, nine factors were identified significantly through RDA analysis for explaining NDVI variance: average slope, temperature, flat slope, northeast-facing slope, rainfall, east-facing slope, southeast-facing slope, west-facing slope, and northwest-facing slope, which reflect an intimate connection between climatic and orthographic factors with vegetation. Furthermore, the rainfall and temperature represent different variations in all scenarios and seasons. With consideration of the characteristics of the clusters and significant environmental factors, corresponding climate change adaptation strategies are proposed for each cluster under climate change scenarios. Thus, the results provide insight to assess the natural clustering of the upstream watersheds in Taiwan, benefitting future sustainable watershed management.

“…Proper water behavior can reduce the waste of local water resources [48] and effectively reduce water consumption. However, statistically, Taiwanese people are accustomed to consuming large amounts of water [7]. Hence, we hypothesize that the water behavior of the public has not changed, even under the crisis of water shortage.…”

“…In the face of the water shortage crisis, the government has announced the regulation of irrigation water, implemented artificial rainfall, and even issued a document encouraging Taiwan's water-related leisure industry to voluntarily suspend operation in order to conserve water. Taiwan's reservoirs have been heavily silted up [67], and their storage capacity is obviously reduced [7,11,12]. However, the government has not seized the opportunity to dredge reservoirs, repair reservoir storage facilities, or maintain the environment of lakes during the dry season.…”

“…Taiwan has good control over water resources and sanitation quality [69,70], and the quality of life is high. However, being an island country surrounded by sea with short waterways that flow fast, Taiwan has difficulty in storing fresh water [7,11,12]. Although people are facing a water shortage crisis and their work will be affected by the water limitation, they are more concerned about the safety and the health issue of drinking water at the moment.…”

This phenomenon has a great impact on the hydrological system of the world, including Taiwan [6,7]. Climate change will alter the regional climate, temperature, humidity, and atmospheric pressure, which in turn will affect rainfall and lead to…”

This study assessed people’s water literacy awareness, attitudes, and behaviors to iden-tify strategies for coping with drought and water scarcity. The data from 653 questionnaires were analyzed by statistical validation and using IBM SPSS 22 and IBM AMOS 26.0. The views of students, housewives, swimming pool owners, schoolteachers, and experts were collected and finally examined by multivariate validation analysis. People have a high level of water literacy and developed sufficient water-saving habits (4.60). Although most people believe that tap water is of good quality, it is difficult to deliver and expensive, and cannot be consumed directly. Even though people are aware of the water shortage crisis, willing to carry water bottles instead of using plastic bottled water, choosing to buy environmentally friendly cleaning products (4.08), performing water conservation behaviors on the go, taking showers within 6–15 min, and taking the initiative to notify the relevant authorities to repair water facilities, the frequency of using bottled water is still high due to work and living habits, consumption ability, and mobility constraints (34.6), and they are less willing to buy products with the “water proficiency label” (4.08) and participate in stream-cleaning activities (3.57). The willingness to participate in water purification activities is low. The public also feels that the government is responsible for solving the current water shortage crisis (3.71). There are significant differences in the perceptions, attitudes, and behaviors of water literacy among people of different genders, ages, and regions, depending on their work and consumption abilities, quality of life, and convenience (p < 0.05). Increasing water responsibility can enhance environmental management actions, consumer economic actions, and civic actions, while enhancing water perceptions and crisis awareness can further strengthen civic behaviors.

Evaluating climate change effects on hydrological functionality and water‐related ecosystem services

The paper investigates the effects of climate change on riverine ecosystems in the Upper Arno River basin, adopting a hybrid methodology relating the changes in streamflow to its related water ecosystem services. Twenty hydrological models were run using the Soil and Water Assessment Tool (SWAT), under their respective climate model and emission scenario. The streamflow variable obtained was analysed according to the method of Indicators of Hydrologic Alteration (IHA). The development of spatial maps of IHA allowed us to represent the spatial of the results according to the three river subbasins studied, with a focus on the presence of hotspots. Using IHA allowed to capture of the streamflow quantity and dynamics, through groups of magnitude, timing and rates, where the potential effect could be then linked to the concept of water ecosystem services. Finally, the results obtained were presented as a proxy that can be integrated into the existing Driver, Pressure, State, Impact, Response (DPSIR) management framework to eventually move towards an ecosystem‐based management methodology. The main results, induced from the Mann–Kendall trend analysis of the IHA, suggested that provisioning and regulating services are to be affected by climate change where the quantity of flows shows a decreasing trend under several emission scenarios, in addition to an intensification of the extreme events. This shift is accompanied by a change in the dynamics of flow, which holds the potential of affecting habitat suitability. With the emergence of studies directed towards ecosystem‐based management, the study refers to well‐established hydrological modelling to evaluate climate change as a driver and provide screening results to ensure a proactive response planning that converges with the idea of ecosystems.
