Topographic Influences on Household Distance to Water Points in Mountainous Lake Victoria Settlements, Tanzania

Abstract

Limited access to water services in urban areas has focused primarily on infrastructural deficits, with comparatively little attention to environmental factors, especially topography, and their relationship to household distance from water points.  Consequently, empirical evidence on the role of environmental conditions in shaping household distance to water points remains limited. However, understanding the relationship between topography and household distance to water points can inform context-sensitive planning strategies aimed at improving access to water services.   This study examines the association between topography classified as gentle slope (0-5⁰), sloping landscape (6-15⁰), and steep slope (16-30⁰) and household distance to water points, drawing on Urban Political Ecology as a theoretical framework for analysing power relations.  A mixed method approach was adopted, integrating household survey and key informant interviews to explore this relationship.  Data analysis was conducted using descriptive statistics, chi-square tests, GIS and content analysis. The findings indicated that residents located in gentle slope areas tended to access water points at comparatively shorter distances, followed by those in sloping landscapes, while residents in steep slope areas were more likely to access water points located beyond 400 metres from their households.  The distances in steep slope settlements are inconsistent with the standards outlined in the Tanzania National Water Policy. The proportion of households located beyond 400 metres from water points was 14.72% in sloping landscape and 26.79% in steep slope, whereas no such cases were observed in gentle slope areas.   The findings underscore a significant association between topography and household distance to water points. In light of these findings, I conclude that addressing disparities in water access may require greater consideration of terrain-specific conditions, strengthened regulatory enforcement, and improved policy implementation mechanisms.
