Evaluation of the state of water resources using Modified Water Poverty Index: a case study in the Srepok River basin, Vietnam – Cambodia

The Water Poverty Index (WPI) has been recognized as a useful tool in policy analysis. The index integrates various physical, social and environmental aspects to enable more holistic assessment of water resources. However, soundness of this tool relies on two complementary aspects: (i) inadequate techniques employed in index construction would produce unreliable results, and (ii) poor dissemination of final outcome would reduce applicability of the index to influence policy-making. From a methodological point of view, a revised alternative to calculate the index was developed in a previous study. This paper is therefore concerned not with the method employed in index construction, but with how the composite can be applied to support decision-making processes. In particular, the paper examines different approaches to exploit the index as a policy tool. A number of alternatives to disseminate achieved results are presented. The implications of applying the composite at different spatial scales are highlighted. Turkana District, in Kenya has been selected as initial case study to test the applicability and validity of the index. The paper concludes that the WPI approach provides a relevant tool for guiding appropriate action and policy-making towards more equitable allocation of water resources.

Water Poverty Index

As one assessment method of the water resources, Water Poverty Index has become an available tool in water resources management for it simply calculation process, comprehensive understanding of the results. This paper introduces the concept of the Water Poverty Index, and applies it at these districts of Yellow River Basin by using equal weightings methodology. During the process of calculating it, some component variables of the WPI have been improved and the data addressed standardization. The result shows that the water resources of Shandong is safe, Sichuan and Henan province is middling safe and low safe, while the WPI of the other six provinces is so low which reflects water resources shortage is very severe. The same time, this paper analysis the main reasons of water poverty, which provides the access to improve the water resource management in these districts.

Water Poverty Index

Water Poverty Index (WPI) is an effective tool to assess water stress by linking physical approximations of water availability with socioeconomic drivers of poverty at household and community levels. It also helps in determining the priority needs for interventions and makes the better use of water resources without compromising the environmental integrity at the policy level. This study presents a comparative analysis of WPI to assess the water stress in two local units i.e., Mahakali Municipality-4 (Upstream) and Bhimdatt Municipality-13 (Downstream) of the Darchula and Kanchanpur districts, respectively along the Mahakali River Basin (MRB), Sudurpaschim Province, Nepal. Five components, i.e., resource availability, use of resources, capacity to utilize water sources, accessibility to water sources, and environment were applied to appraisal the water poverty. Under these components, 28 indicators were selected to visualize the water poverty condition. The information for acquiring these indicators was collected by making the field visit, semi-structured questionnaire survey, and secondary information from relevant sources. The results showed that the downstream segment has a higher WPI value (65.43) in comparison to the upstream segment (52.60) of the MRB, indicating relatively water-advantaged and stressed situations in down- and up-streams, respectively. Interestingly, despite having higher resource availability, the upstream region exhibited more stressed situations reflecting spatial heterogeneity in terms of capacity, environmental conditions, and infrastructure development to use the available water resources. Thus, in order to reduce the water stress conditions, priorities for intervention must be given to the water use capacity, especially in the upstream segment of the MRB. This study could be useful for academia and policymakers for the sustainable use of water resources in the MRB, Susurpaschim Province, Nepal.

RESUMO: O presente trabalho tem a proposta de avaliar a eficácia de duas metodologias de avaliação de risco de uma barragem no Nordeste Brasileiro no intervalo de 10 anos, baseando-se na inspeção e no nível de ameaça. Utiliza-se a metodologia Nível de Perigo da Barragem (NPB) para cálculo do nível de ameaça (Fontenelle, 2007) e para o cálculo do risco as metodologias da Companhia de Gestão dos Recursos Hídricos do Ceará (COGERH) e do Conselho Nacional de Recursos Hídricos (CNRH). Observa-se que o crescente número de barragens soma-se a preocupação com a segurança destas. Face a isto, utiliza-se a avaliação de risco como forma de priorizar ações de manutenção e recuperação. O estudo de caso ocorreu na Barragem Malcozinhado, localizada no município de Cascavel, no estado do Ceará. Com base na inspeção, calcula-se o nível de ameaça e o risco, compara-se estes com os resultados de 2006. Assim, observou-se o aumento no nível de ameaça, no entanto, o risco permaneceu, em geral, baixo, semelhante aos resultados de 2006. Este resultado se deve ao fato de que o número de anomalias aumentou, porém trata-se de uma barragem jovem, de pequeno porte e inspecionada regularmente.ABSTRACT: The present study has the proposal of evaluating the effectiveness of two methodologies of risk Assessment of a Brazilian Northeast dam in a range of 10 years, based on the inspection and the level of hazard. The methodology used for calculating the hazard level is the Dam Hazard Level (NPB). In addiction, in order to evaluate the risk is used the methodology of the Water Resources Management Company of Ceará (COGERH) and the methodology of National Resources Council Water (CNRH). The number of dams is increasing with to the concern for their safety. In view of this, risk assessment is used as a tool to prioritizing maintenance and recovery actions. The case study occurred in the Malcozinhado Dam, located in the municipality of Cascavel, in the state of Ceará. Based on the inspection, the level of hazard and risk is calculated, compared to the results for 2006. Thus, the increase in the level of hazard was observed, but the risk remained generally low, similar to 2006 result. This result is due to the fact that the number of anomalies has increased, but it is a young, small and regularly inspected dam.
