Sustainability Indices

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.

Index Value

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.

This paper will describe the function of water resources to support business activities in Surakarta regency, Central Java province. Surakarta is a business city in Central Java province with small business enterprises and specific culture. This city has a famous river with the name is Bengawan Solo. Bengawan Solo is a River Flow Regional (RFR) to support business activities in Surakarta regency. Concious with the function, societies and local government in Surakarta must to manage the sustainability of River Flow Regional (RFR) Bengawan Solo. It is important to manage the sustainability of business activity in Surakarta regency.   According to the condition in Surakarta regency, this paper will explain how the simulation of Low Impact Development Model in Surakarta regency. Low Impact Development is a model that can manage and evaluate sustainability of water resources in River Flow Regional (RFR). Low Impact Development can analys goals, structures, and process water resources management. The system can also evaluate results and impacts of water resources management. From this study, we hope that Low Impact Development can manage water resources in River Flow Regional (RFR) Bengawan Solo.
