Water Sustainability Index: Application of CWSI for Ahwaz County

Sustainable water resources management is essential since it ensures the integration of social, economical and environmental issues into all stages of water resources management. The development and application of water sustainability indices to achieve sustainable water management has been successfully done in the last few years. Although existing water sustainability indices have successfully provided information on current conditions of water resources and prioritised water related issues, they have been developed for specific case study areas. This study therefore aims at developing a water sustainability index for West Java, Indonesia. The overall steps for developing the index include developing a conceptual framework, application of Delphi technique to finalise the components/indicators of the index, applying the index to case studies and robustness analysis of the index. This paper, which is the first in a two-part series, discusses the first step, namely developing the conceptual framework of the West Java Water Sustainability Index (WJWSI). It outlines the criteria for identifying the initial set of components/indicators and based on those criteria, a detailed justification for selecting each component and indicator is also presented. The second paper of the series presents the application of Delphi technique to finalise the framework of WJWSI based on feedback from selected stakeholders. The remaining steps of developing WJWSI will be undertaken in the future.

In the first paper of this two-part series on the development of a water sustainability index for West Java, a conceptual framework of West Java Water Sustainability Index (WJWSI) was developed. It consists of three main parts: components, indicators/sub-indicators and threshold values. This second paper of the series presents the application of the Delphi technique, followed by in-depth interviews with selected key experts, to refine the conceptual WJWSI framework. The Delphi application includes the design of the questionnaires, the selection of respondents, the distribution and collection of the completed questionnaires and the analysis of data. After Round One of the Delphi application, the respondents reached consensus for all proposed components in the conceptual framework. However, some modifications to the components were also suggested by few respondents. Regarding the indicators/sub-indicators, consensus for 9 of the proposed 12 indicators was reached, and 5 new indicators were suggested. For the threshold values, consensus was reached for threshold values of 5 indicators. In Round Two of the Delphi application, respondents were asked questions related to results from Round One, which include the modification on the components, indicators/sub-indicators which have not been agreed, and newly suggested indicators/sub-indicators and threshold values. Results of Round Two show that modifications on the components were agreed, and consensus was reached for 8 out of the proposed 9 indicators/sub-indicators. In terms of its components and indicators, the framework was then finalised in the in-depth interview with four key experts, selected from different respondent categories. For the threshold values not yet finalised, further study will be carried out, as there was not much input from the respondents in the Delphi application and the in-depth interview.

Indus River Basin

The sustainability index identifies a strategy that defend or improve the desired water management features of the basin in the future. The Upper Indus river basin is a high mountain region and consider third freshwater tower. The flow of the river consists of melting glaciers, snow, rainfall. Beyond the polar regions, the Upper Indus Basin has the largest area of glaciers in the world (22,000 km2).&#160; About 220 million people depend on Indus Basin water for agriculture and drinking purpose. Under the changing climate, sustainability is becoming a challenge for the freshwater resources. The integration of climate variables with RRV indicators is a new approach to meet this challenge. In this study the sustainability of the upper Indus is quantified. The probabilistic concept of resilience, reliability and vulnerability is applied to rainfall variability and drought patterns. The monthly Standardized Precipitation-Evapotranspiration Index (SPEI) grided data (0.5o 0.5o) generated by climate research unit (CRU)version 4 has been used for study during the period 1901&#8211;2018. Based on the SPEI pattern, the SPEI of -0.5 was selected as the threshold (demand) to evaluate the sustainability. The results indicate the frequency of drought events in the western part of the basin is much higher than the eastern part. However, the frequency of drought events in the basin is high but the capability of the basin to resilient the droughts varies from 0.57 to 0.83. The value of reliability indicator varies from 0.8 to 0.86 and vulnerability of drought in the basin is in the range of 0.2 to 0.45. The average water sustainability index of the basin is 0.4 which lies in the category of a satisfactory state.The results of the conceptual framework of RRV can provide a more comprehensive basis for designing watershed health variables and drought management plans.&#160;Keywords: Upper Indus Basin, Water sustainability, RRV concept, SPEI, Drought.

Water authorities in West Java, Indonesia have difficulties in implementing water improvement programs due to lack of tools for prioritisation of water-related issues and their respective programs. To facilitate more efficient management of the water resources, the West Java Water Sustainability Index (WJWSI) was recently developed. This paper outlines the tasks for developing WJWSI and highlights the results of its application in one of West Java catchments, Citarum catchment. The results showed that five out of the thirteen indicators and sub-indicators, namely ‘Water Availability, Water Quality, Education, Water Loss and Poverty’, had low sub-indices and thus had poor performances. Then, the sub-indices were aggregated using the geometric aggregation method to produce the final index. The results of the aggregation indicated that the overall condition of water resources in Citarum catchment was considered poor, with a final index value of 20.04. Based on the WJWSI application, recommendations are suggested to the relevant authorities in the Citarum catchment. It is expected that the implementation of these recommendations will improve the performance of these five indicators and sub-indicators from Poor to at least the next higher level of Poor–Medium, thus improving the value of the final index from 20.04 to 37.19.

Abstract This paper proposes an adaptation of the Rural Water Sustainability Index (RWSI) to the Brazilian Amazon region. Policymakers can use this tool to identify areas of water stress and develop actions to guarantee water access to rural communities. Multi-criteria analysis and a geographical information system were integrated to incorporate various indicators and produce maps displaying spatial water sustainability levels in rural communities. The RWSI was employed on a case study at 16 rural communities in Santa Luzia do Pará, Pará, Brazil. In total, 380 closed and structured interviews were conducted with people living in the area to collect local information for the model application. The results showed a varied spatial behavior between rural communities of Santa Luzia do Pará, with similarities and differences based on the overall condition of water resources (final index values). Half of the locations had ‘Poor’ or ‘Poor-Medium’ water quality. The remaining sample obtained scores ranging from ‘Medium-Good’ to ‘Good’ water sustainability. RWSI’ scores varied widely (from 5.7 to 6.5) among the communities. It was also found that localities more distant from surface water presented more water stress.
