Traditional Water Resource Management and Water Quality in Rural Tanzania

Abstract

Traditional resource management (TRM) is largely based on local ecological knowledge (LEK). In regions where formal institutional control of natural resources is limited due to a lack of coordination or stakeholder involvement, communities rely on TRM to manage common-pool resources. This paper examines TRM among the Sonjo in rural Northern Tanzania, with particular reference to catchment forest protection and water quality. We first document the ecological knowledge of traditional resource managers, and then describe the differences between traditionally managed water sources and formal, government managed resources. Using both qualitative and quantitative methods to examine water use, perceptions of water quality, and bacterial water quality, significant differences were detected among river basins within seasons and between seasons. Our findings indicate that the Sonjo, well known for their traditional forest conservation practices and irrigation management, may also benefit from TRM through improved water quality. The examination of traditional methods of water conservation provides insight into how communities in resource-stressed regions thrive despite seasonal droughts and flooding.

Self-supply as an alternative approach to water access in rural scattered regions: evidence from a rural microcatchment in Colombia

“…There were no statistically significant differences between rainy season, compared to the dry season (Mann-Whitney, p = 0.6188). The lack of statistically significant differences in microbial water quality between seasons contrasts with studies in rural areas of Tanzania [31] and Ecuador [30], where higher microbial levels were found in domestic sources in rainy season, associated with faecal contamination in the surrounding environment flushed to water sources due to increased runoff. In Calabazas, this lack of statistically significant differences between seasons may be explained on the fact that 95% of the population had access to improved sanitation [1], from which 45% included secondary treatment systems.…”

Infection, colonization and shedding of Campylobacter and Salmonella in animals and their contribution to human disease: A review

“…Indistinguishable strains connected to Campylobacter waterborne outbreaks occurring during heavy rains were documented in humans, cattle and manure implying water source contamination by water run-off from animal farms (Clark et al, 2003). In resource-poor settings, water source sharing between humans and animals is not uncommon resulting in use of water contaminated by animal faeces (Kusiluka et al, 2005;Lyimo et al, 2016;Strauch & Almedom, 2011). The isolation of similar Salmonella strains in domestic and non-domestic animals in rural and urban surface water further confirms animals as reservoirs for environmental and water bacterial contamination (Thomas, Slawson, & Taylor, 2013).…”

Primeiramente, se zerou pelas veredas, pelos olhos d`água que a gente chama, pelos córregos, pelos afluentes, a destruição da mata ciliar, a destruição da floresta.…”
