Doctoral thesis for water quality

I investigate the usefulness of using a combination of food security and personal wellbeing indices that I develop together with other standard qualitative tools, to highlight aspects of livelihoods sustainability that are not covered by conventional poverty approaches. I also apply these approaches to assess first, how certain coastal zone management policy processes such as Special Area Management SAM has affected rural coastal livelihoods, and later, to assess the impact of the Asian tsunami on coastal communities and their livelihoods.

SAM is a co-management approach applied in specific coastal sites. I collected data from a total of households that covered 6 villages 3 villages in each site.

The Perfect Defense: The Oral Defense of a Dissertation

A combination of participatory methods and conventional surveys methods were used. I first examined the major qualitative trends and influences, and thereafter investigated the differences between households within and between villages and between male and female respondents using univariate analyses. Finally, regression analyses were used to relate the food security and personal well-being indices to a number of explanatory variables such as location of village, wealth rank, livelihood activities and SAM participation.

My findings suggest that in terms of coastal resource management initiatives, the use of indices and tools such as those developed under this study, could prove to be useful in respect to better targeting the poorer groups among coastal communities. This in turn would contribute towards the overall success and long-term sustainability of coastal zone management initiatives. Aloysius, Noel.

This thesis has explored a water quality assessment with the aid of Geographical Information System GIS and its applications for subsequent manipulations and analyses based on a case study of water supply for the City of Nairobi.

For exploratory analyses of existing water quality data, a GIS software package, the statistical function "Analyzing Patterns and Mapping Clusters" was applied for data manipulations and analyses. The analyses were made based on selected indicator parameters of existing water quality data.

The analyses result showed that some of indicator parameters of the water sources and distribution are spatially or regionally variable while others are randomly distributed. Parameters' values were also evaluated in relation to established water quality standards.

Based on parameters variability and assessments, it was possible to get information with respect to water quality conditions and status of sources and distributions. The information is useful for implementing control measures and improvements to the water supply system. Furthermore, the study result has revealed some constraints and allowed development of recommendations on the current water quality management system for the City of Nairobi Water Supply.

Thus, this case study has proved the validity and applicability of GIS for water quality. In other words, very few studies have been done into household private level water supply. The Self Supply model may give significant benefits for sustainable safe water supplies, especially in sparsely populated rural areas, in comparison with the communal water supply though to date there has been little monitoring and systematic analysis of what impact these changes have made at the grassroots level. The standpoint of this study is pragmatic, and herein, mixing quantitative and qualitative methods was justified in order to design the research methodologies.

The research was conducted in the Luapula Province of Zambia using a concurrent triangulation strategy to offset the weakness inherent within one method with the strengths of the other.
