  1. Determinants of Water Access Brian Banks bb4934a@american.edu American University School of International Service

  2. Research Question & Hypothesis • What factors determine the percent of the population with sustainable access to water? • Hypothesis: Prosperity, education, and governance are significant determinants of water access.

  3. Background Info or Lit. Review • Theory and Findings from: Decentralization on Access to Rural Water Supply Services: A  Study of Six Villages in West Bengal, India • Theory: Access to water at the individual level is positively correlated with education, socio-economic standing (caste), and participation in local government. • Findings: The type of water source was found to be significant in all models, and education was significant in one model. • Theory and Findings from: International Investments in the Water Sector • Theory: Health impacts from water investment witness an “S” shaped curve, with both a threshold and a saturation point • Findings: Logistic curve had an R2 value of 50% for low access countries and 56% in high access countries. Both were significant, although, of note, N=65.

  4. Data • Unit of Analysis: Country • Source: Pippa Norris Democracy Cross-national Data 2008 • Dependent variable is % of population with sustainable access to an improved source of water • Unit of measurement is % of population, and this is interval-ratio level • Independent Variables: • Gross Domestic Product per capita (purchasing price parity), in year 2000 dollars, and this is interval-ratio level. • Adult literacy rate 1998, and this is interval-ratio level. • Transparency International Corruption Perception Index for 2007, which is interval ratio.

  5. Descriptive Statistics

  7. Bivariate analysis Pearson’s Correlation (Significance) [N]

  8. Regression Analysis, % of Population with Access to Sustainable Clean Water

  9. Findings & Policy Implications of the research • Findings: GDP and Literacy were both significant at alpha=.05, and this model explains 46.8% of differences in water access. • Policy: • Improving the education will, in turn, improve water access, providing an opportunity to reach two objectives with one investment. • Investment may have better outcomes in countries with higher GDP per capita and higher literacy rates, increasing return on investment.
