Uncovering how groundwater is used, in Tanzania

re-posted from: Grofutures.org

The GroFutures team in Tanzania has just completed the data collection component of the Participatory Rural Appraisal (PRA) exercise in the Great Ruaha Basin of Tanzania. The team comprised Andrew Tarimo, Devotha Mosha Kilave, Gebregziabher Gebrehaweria and Imogen Bellwood-Howard. Following initial training at Sokoine University of Agriculture, the team moved to the study site in Mbarali District and worked in three villages (Matebete, Ubaruku and Nyeregete) between 23rd August and 2nd September 2017. During the PRA exercise the team carried out a range of activities including seasonal calendars development, long-term trend analyses, wealth indexes, technology rankings and a well inventory (see photos below).

The team documented a range of groundwater and other water use strategies involving dug wells, shallow and deep groundwater wells alongside surface water and natural springs. With the well inventory, the team was able to locate geographically groundwater sources within the study areas. The PRA exercises allowed the team to make qualitative characterisation of different water sources. Preliminary data include the observation that wealthier people were often beginning to invest in more expensive, private infrastructure. Quality was a concern as much as quantity, which was highly relevant in the light of recent health scares. A detailed analysis of the entire survey dataset is curently being carried out by the team.
