Special Issue Information

Dear Colleagues,

Due to the global geodistribution, water-resource-related problems in arid and semi-arid regions are aggravating at present. In general, these problems are complex not only due to technical and economic parameters, but also due to the policy and institutional framework, human resource development, and sociocultural reasons. There is no doubt that we have some excellent showcases and good experience to manage water resources in these regions at the world level, but these problems have still not been solved in most arid and semi-arid regions, and more attention should be paid to facing and solving them.

The aim of this proposed special issue is to reflect the wide variety of water-resource-related topics with their inherent complexity and to highlight the successful showcases and experience to share with global academic peers, industrial partners, and policy makers. The issue will review the nature of the problems that are emerging in water resource management, and policy and institutional challenges of concern. It will also focus on the water resources strategies and options whichare important in research, policy, and human resources in order to successfully respond to these challenges. The issue will finally identify future water resource research areas. It is expected that this Special Issue will make a different contribution in water resource practice for various communities and countries around the globe, but with special focus on China.

Potential topics to cover:

1) Profile of water resources in arid and semi-arid regions

2) Various approaches for mapping the water resource profile

3) Wiser application of remote sensors in mapping water resources

4) Lessons learned from the past for water resource management in arid/semi-arid regions

5) Potential and perspectives of water resource management in arid regions

6) Insight into water resources in arid and semi-arid regions

7) Developing new strategies for managing water resources in arid and semi-arid regions

8) Updating various technical solutions for water resource management in arid regions

9) Water problems and solutions of agricultural use in arid regions

10) “Smart city” solutions in arid and semi-arid regions

11) “Sponge city” construction in arid and semi-arid regions

12) “Proof of concept” of eco-solutions for water resource protection in arid and semi-arid regions

13) Challenges and strategies of water resource management under Chinese fast economical development

14) Integrated consideration of solid waste management in arid and semi-arid regions

Hydrological cycle is sensitively affected by climatic variation and human activity. Taking the upper- and middle-stream of the Weihe River in western China as an example, using multiple meteorological and hydrological elements, as well as land-use/land-cover change (LUCC) data, we constructed a sensitivity model of runoff to climatic elements and human activities based on the hydro-thermal coupling equilibrium equation, while a cumulative slope was used to establish a comprehensive estimation model for the contributions of climatic variation and human activities to the changes of runoff. The results showed that the above function model established could be well applied to quantitatively study the elasticity of runoff’s response to climatic variation and human activities. It was found that the annual average precipitation, evaporation, wind velocity, sunshine hours, relative humidity and runoff showed decreasing trends and that temperature increased. While in the hydrological cycle, precipitation and relative humidity had a non-linear positive driving effect on runoff, while temperature, evaporation, sunshine hours, wind velocity, and land-use/land-cover change (LUCC) have non-linearly negatively driven the variation of runoff. Moreover, runoff has a strong sensitive response to precipitation, evaporation and LUCC. In areas with strong human activities, the sensitivity of runoff to climatic change was decreasing, and runoff has a greater elastic response to underlying surface parameters. In addition, the analysis showed that the abrupt years of climate and runoff changes in the Weihe River Basin were 1970, 1985 and 1993. Before 1985, the contribution rate of climatic variation to runoff was 68.3%, being greater than that of human activities to runoff, and then the contribution rates of human activities to runoff reached 75.1%. The impact of natural climate on runoff was weakened, and the effect of human activities on runoff reduction increased. Under 30 hypothetical climatic scenarios, the evaluation of runoff in the future showed that the runoff in the Weihe River Basin will be greatly reduced, and the reduction will be more significant during the flood season. Comparing the geographically fragile environments and intense human activities, it was believed that climatic variation had a dramatic effect on driving the water cycle of precipitation and evaporation and affected regional water balance and water distribution, while human activities had driven the hydrological processes of the underlying surface, thus becoming the main factors in the reduction of runoff. This study provided scientific tools for regional climate change and water resources assessment. Full article

Electrochemical oxidation technology is an effective technique to treat high-concentration wastewater, which can directly oxidize refractory pollutants into simple inorganic compounds such as H2O and CO2. In this work, two-dimensionally stable anodes, Ti/RuO2-IrO2-SnO2, have been developed in order to degrade organic pollutants from pharmaceutical wastewater. Characterization by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) showed that the oxide coating was successfully fabricated on the Ti plate surface. Electrocatalytic oxidation conditions of high concentration pharmaceutical wastewater was discussed and optimized, and the best results showed that the COD removal rate was 95.92% with the energy consumption was 58.09 kW·h/kgCOD under the electrode distance of 3 cm, current density of 8 mA/cm2, initial pH of 2, and air flow of 18 L/min.
