This project deploys a modified Water Poverty Index (WPI) in villages reconstructed after the 2004 tsunami in southeastern India. While previous measurements of access to water have advanced understandings of waterscape complexities, this modified WPI improves past efforts and deconstructs some of the previous misunderstandings and notions regarding access to water. The traditional WPI is multidimensional and seeks to measure water access in a holistic fashion; the WPI presented here employs this approach, but is adapted to include new place-based indicators (e.g., Secondary Sources). Furthermore, unlike previous iterations of the WPI, our modified index incorporates water quality testing, three weight schemes, and operates at several scales. Ultimately, the construction and arrangement of our modified WPI enables statistical analyses, geospatial analyses, and water poverty mapping -- which are absent in most prior studies-- while still remaining easy to populate and descriptively analyze among non-academicians. Statistical tests of original household level data from a total of 24 villages in Nagapattinam District, Tamil Nadu, and Karaikal District, Puducherry, indicate significant differences between the two districts in indicator scores as well as total WPI score. Additionally, the urban and rural areas within each district were found to be significantly different in level of water poverty, and trends were similar across the three weight schemes. Multiple linear regressions show correlation of independent socioeconomic variables (i.e., Income, Education, and Assets-Networks) with the dependent indicator of Capacity, but not with the other indicators or total WPI score. Global Moran's I tests indicate positive spatial autocorrelation, demonstrating that indicator and WPI scores tend to cluster in space. Overall, the results match what was anticipated, yet serve to challenge commonly held assumptions on urban-rural hierarchies and the role of socioeconomic variables in determining water poverty. The construction, deployment, and analytical potential of this modified WPI can be used by scholars to improve existing conceptualizations and measurements of access to water, while the results can be used by local governments and nonprofits to improve resource allocation and inform spatially-targeted interventions. / Master of Science

Floating macrophyte pond systems, with the ability to produce nutrient enriched plants simultaneously with wastewater treatment, are a sustainable solution to contribute to environmental protection and safe nutrient recovery from domestic wastewater. However, to meet the requirements for reuse with high strength wastewater containing high levels of metal pollution generated in developing countries, an adequate combination of water hyacinth and duckweed ponds is proposed in order to take advantage of the best characteristics of each of these macrophyte ponds. This research focused on the advancing of the understanding of the effectiveness of treatment and resource recovery under the effect of changing operational parameters such as pH, light intensity, influent metal content and fluctuating pollutants loading rate on pond performance and recycling ability in order to fill the noticed gap of knowledge. Experiments conducted in water hyacinth ponds (WHP), under batch and tropical natural weather conditions, revealed that pH between 6.4 and 7.1, full sunlight and seven days hydraulic retention time were optimum for plant biomass production and pollutant removal in WHP. WHP was able to regulate pH when the initial pH values moved outside this interval with a drop in biomass production as a side effect. These ponds showed a first order kinetic for the removal of iron, zinc and copper from aqueous solution and their accumulation in plants biomass with a preferential sequence Fe > Zn > Cu. However the presence of metals in water hyacinth biomass led to the reduction in ponds performances and a risk of re-pollution of the effluent through the release of metals into water. A comparative study carried out over sixty-two weeks in a pilot scale combined water hyacinth and duckweed ponds (DWP) channel and waste stabilization ponds channel working under fluctuating loading rates showed different environmental conditions occurred these ponds. The fluctuating loading rate was also found to have a reduced effect on the combined WHP/DWP channel performance and effluent quality stability with the effluents meeting the entire reuse requirement at high hydraulic flow rate (retention time greater than 20 days). Fish was able to grow in the WHP/DWP channel. Results suggested some guidelines on WHP/DWP system design, operation and maintenance. The overall outcome of this research is a significant contribution to the development of integrated combined WHP/DWP technology for treatment of wastewater and resource recovery on site.

This dissertation provides an authoritative account of reconstruction in the water sector after the 2004 Indian Ocean tsunami in coastal, deltaic South India. In particular, this study examines 14 newly constructed housing settlements in the adjacent study areas of Nagapattinam District, Tamil Nadu, and Karaikal District, Puducherry. There is currently a paucity of literature dedicated to water components of reconstruction. Thus, this study expands the discourse and posits water elements of post-disaster processes as unique and therefore deserving of increased scholarly attention. The study is informed by a multi-methods approach and a geographical perspective. The methodologies include, inter alia, qualitative and quantitative survey instruments; key informant interviews; focus group discussions; the employment of primary documents; and environmental analyses through bacteriological and chemical water quality testing. Geographically, data, information, and actions are perceived as the coalescence of localized socio-cultural, politico-economic, and environmental fabrics. This approach to viewing circumstances is imperative for dissecting the outcomes of reconstruction processes in a specific context, and consequently for understanding problems, identifying solutions, and gauging the appropriateness of particular configurations in place-based systems. This dissertation critiques the models utilized for reconstruction in the two study areas. The scales of inquiry are demographically and geo-physically similar, yet differ in political organization. It is argued that Nagapattinam executed a model of reconstruction founded on collaborative governance, while Karaikal exercised a single agency approach. Thus, various governmental agencies were responsible for specific reconstruction activities in Nagapattinam, whereas a single agency was responsible for all activities in Karaikal. In general, the latter approach, which was less layered, produced comparatively better outcomes. Moreover, both jurisdictions implemented 'hard' paths for water management and operationalized panoptic and revenue-based methods of reconstruction, albeit inefficiently. Numerous shortcomings in reconstruction outcomes were uncovered (e.g., water quality, quantity, and pressure), as were an array of organic coping mechanisms established by affectees in order to surmount such inadequacies. To that end, it is contended that: the coping mechanisms fail to remedy the condition; much of the waterscape is beyond the control of the subjects; and the governments are ultimately deficient in responding to the needs of their citizens. The post-tsunami waterscapes are also analyzed quantitatively through the development of a contextualized, multi-scalar Water Poverty Index (WPI). The WPI is deployed with three distinct weighing schemes and reveals that, on the whole, the sites situated in Karaikal generally perform better than those in Nagapattinam. Interestingly enough, the sites located in rural Nagapattinam outperform their urban counterparts. This case--primarily a product of different water treatment processes--challenges conventional rural-urban dichotomies. Given the occurrence of poor water quality, an investigation of boiling as a method of household water treatment (HWT) surfaces several barriers to and caveats of its adoption. Data indicate that boiling is less effective than could be; thus, it is argued that boiling may not be the optimal strategy for HWT. Lastly, advised by the corpus of data, this dissertation presents a novel framework for managing water components of post-disaster reconstruction. The framework identifies common project failures, can be harnessed independently or alongside existing instruments, and possesses diagnostic, management, and evaluative potential.

The availability and management of water resources is a global issue, this is particularly true in countries with limited water resources, such as Palestine, which falls under the Water Stress Line (1000 m3/person/year)1. Palestine has operated under an -unstable political, economic and social conditions for more than six decades. This uncertainty has resulted in mismanagement, inefficient institutions and the over-xploitation of water resources. The main aim of this study was to produce socioeconomic indicators based on the water tariff structure in order to be pro-poor and to enable water utilities to cope with uncertainties. The study s recommendation is for a flexible, pro-poor and socially acceptable tariff structure have been based on empirical work and socio-economic data which has been collected by rigorous research and reinforced with case studies. Initial results based on a pilot survey showed that there was a 33% increase in the revenue of the water supplier equivalent to 13% of the total water costs and an increase in the number of beneficiaries that paid their bills ranging from 10.5% to 38.6%. If applied at national level, the model application based on current socioeconomic data would have a wide positive socio-economic impact in reducing poverty, financial equality, social security and reduction of the effect of uncertainties. The reform of the existing legal and institution framework are a prerequisite for the application of this kind of model. Institutional and legal reforms coupled with the application of this model, would produce a dynamic water pricing policy as part of the efforts to have an integrated water management and would serve as a tool for the national goal of poverty alleviation and food security.

Foram empregados indicadores existentes na literatura nacional e internacional, relacionados à Capacidade (A), Recursos Hídricos (RH), Uso (U), Acesso (A) e Meio Ambiente (MA). As informações foram obtidas por meio da realização de entrevistas de uma parcela representativa da população da área de estudo. Os resultados mostraram que 85,7% das comunidades rurais pesquisadas tiveram um desempenho regular e o restante, o que equivale a duas comunidades, apresentaram um desempenho bom em relação ao Índice de Pobreza Hídrica. Ratificou-se ainda a importância da utilização das tecnologias sociais hídricas para amenizar a insuficiência ou escassez hídrica nas comunidades pesquisadas. Porém, verificou-se que é fundamental expandir os programas realizados para que um maior número de habitantes das comunidades rurais possa ter acesso e segurança hídrica, possibilitando condições adequadas para sua permanência no campo e uma melhor qualidade de vida. Concluiu-se que o IPH é um importante instrumento que pode ser utilizado para auxiliar as autoridades públicas na elaboração de projetos e estratégias que visam atenuar problemas referentes à questão da escassez hídrica em comunidades rurais. / This study aimed to assess the water situation of the rural population of the municipality of Pombal - PB, using the water poverty index, in order to contribute to the development of strategies and activities aimed at water resources management and the decision making. Were employed indicators available of national and international literature, related to the Capacity (C), Resources (R), Use(U), Access (A) and Environment (E). The information was obtained through interviews of representative portion of the population of the study area. The results showed that 85.7% of the rural communities had a regular WPI, while only two communities presented performed well in relation to Poverty Index water. If ratified the importance of using water social technologies to mitigate the water scarcity in the surveyed communities, however, it was found that it is critical expand the programs carried out so that a greater number of people in rural communities have access and water security, providing appropriate conditions for their stay in the country and a better quality of life. It was concluded that the WPI is an important tool that can be used to assist public authorities in preparing projects and strategies to mitigate problems related to the issue of water scarcity in rural communities
