Professor Japhet Kashaigili presented recent research from the GroFutures Site Observatory in Tanzania (Makutapora) at the 4th Annual Conference (AWAC 2016) of the Association of Tanzanian Water Suppliers (ATAWAS) held on 8th and 9thNovember 2016 in Dodoma, Tanzania. Under the theme of “Knowledge, Capacity and Learning in the Water and Sanitation Sector,” the development of water supplies and sanitation as well as the current challenges faced by organisations across Tanzania were discussed by professionals working in water sector including policy makers and those involved water governance.
Professor Japhet Kashaigili, based at Sokoine University of Agriculture (SUA), presented a paper entitled, Assessing the sustainability of groundwater-fed water supplies to intensive pumping and climate variability: evidence from detailed monitoring of the Makutapora Wellfield, drawing on collaborative research conducted by SUA, University College London, University of Sussex (UK), and the WamiRuvu Basin Water Board within the Ministry of Water and Irrigation. Key stakeholders including the Dodoma Regional Administrative Secretary and Technical Manager of the Dodoma Urban Water Supply and Sanitation Authority (DUWASA) expressed great interest in the GroFutures Team’s evaluation of the sustainability of intensive groundwater abstraction from the Makutapora Wellfield, which is currently the sole perennial supply of freshwater to the rapidly growing capital city, Dodoma. Japhet’s presentation highlighted the bias in wellfield replenishment (recharge) to heavy rainfall and the observed dependence of recharge on the duration of ephemeral river discharge to the wellfield. He also reported on the establishment of telemetry-based, high-frequency (hourly) monitoring of groundwater levels in boreholes enabling the WamiRuvu Basin Water Board and GroFutures team to download real-time monitoring of groundwater levels for wellfield management and research.

On August 22nd and 23rd, a stakeholder workshop to kick off the GroFutures comparative study in the Iullemmeden basin was held at Université Abdou Moumouni in Niamey, Niger. During this workshop, IGRAC and the GroFutures Team facilitated a session of the Groundwater Serious Game that was attended by 28 participants. Among the participants of the game session, there were researchers from the university (professors and students), local authorities, hydraulic engineers from local organisations as well as farmers using groundwater to irrigate their crops. The game session, which featured simultaneous translation into French and Haoussa, helped the project team and the stakeholders to better understand the groundwater dynamics and the challenges to be faced in the coming years.
After the session the team had the opportunity to discuss the experience during the game session and to highlight the importance of opening up the discussion of sustainable and joint management of the groundwater resources as a shared resource (domestic and irrigation uses, surface water versus groundwater). The Groundwater Serious Game session also proportioned a good integration of the stakeholders of the Iullemmeden basin in a lucid and dynamic way.
The Serious Game on Improving Groundwater Management Through Cooperation and Collective Action, developed by IGRAC, is being applied to case studies of GroFutures (Groundwater Futures in Sub-Saharan Africa), a 4-year research project, funded by the UK government under its UPGro(Unlocking the Potential of Groundwater for the Poor) programme, seeking to develop the scientific evidence base, tools and participatory processes by which groundwater resources can be used sustainably for poverty alleviation in Sub-Saharan Africa (SSA). This project involves comparative studies in Ethiopia (Upper Awash Basin), Niger and Nigeria (Iullemmeden transboundary Basin) and in Tanzania (Great Ruaha Basin).

On April 4th and 5th 2016, members of the GroFutures Team visited the Makutapora Wellfield in central Tanzania to observe up close and with project partners, WamiRuvu Basin Water Office of the Ministry of Water, rare flood conditions that are associated with the 2015-16 El Niño Event and, it is expected, conditions favourable for episodic replenishment of the wellfield by recharge. In advance of the El Niño Event, the GroFutures Team established high-frequency sensors to monitor both surface water and groundwater levels resulting from what was expected to be anomalously heavy rainfall associated with the 2015-16 El Niño Event. The team was not disappointed by the rain but road conditions did present challenges to the downloading of data from installed sensors! After getting stuck twice in the very wet roads, the team will return again later in the year when conditions are drier. Nevertheless, a lot was learned from seeing the wellfield basin in flood.
IGRAC developed a Serious Game on ‘Improving Groundwater Management Through Cooperation and Collective Action’, which has been tested and applied to the case studies of the GroFutures project.
Groundwater Futures in Sub-Saharan Africa (GroFutures) will develop the scientific evidence base, tools and participatory processes by which groundwater resources can be used sustainably for poverty alleviation in Sub-Saharan Africa (SSA). This 4-year involves comparative studies in Ethiopia (Upper Awash), Niger and Nigeria (Iullemmeden) and in Tanzania (Great Ruaha) and is funded by the UK government under its UPGro (Unlocking the Potential of Groundwater for the Poor) programme.
A stakeholder workshop to kick off this study in Tanzania was held on March 30th and 31st 2016 in Iringa, followed by a 4-days field trip. The Groundwater Game session was attended by circa 25 participants. Playing the Groundwater Game helped all participants better understand the challenges and consequences of groundwater use and potential challenges to be faced in the future. The integration of stakeholders from a range of perspectives into different teams playing the game also promoted direct sharing of thoughts and ideas in a relaxed manner. During the workshop, the project team welcomed the Director of Water Resources, Regional Commissioner for Iringa, Water Officers of the Rufiji and WamiRuvu Basins together with a range of other key stakeholders including District Water and Irrigation Engineers, local NGOs and farmers.
Under the heading “Using groundwater to reduce poverty” the GroFutures Team in Tanzania led by Japhet Kashaigili, Andrew Tarimo and Devotha Mosha hosted the GroFutures Inception Workshop in Iringa on March 31st 2016. It was opened by the District Commissioner for Iringa, Hon. Richard Kasesela, and was attended by national, basin-level and local stakeholders (listed below) who discussed current groundwater use and management in the Great Ruaha Sub-Catchment of the Rufiji Basin and as well as both proposed and potential groundwater development pathways that might best reduce poverty. The event was featured on national television news in Tanzania (see clip here) and leading newspapers.
New study to examine the potential of groundwater to expand irrigation and increase access to safe water in Tanzania
Groundwater flowing beneath the land surface of Tanzania has the potential to provide year-round sources of freshwater to irrigate crops when rains fail and to supply safe drinking water at low cost. There remain, however, key questions regarding the development of this vital resource including how much groundwater can be used sustainably, what groundwater development pathways will best reduce poverty, and how use of groundwater will affect other water sources such as rivers, wetlands and lakes.

Floods and droughts, feasts and famines: the challenge of living with an African climate has always been its variability, from the lush rainforests of the Congo to the extreme dry of the Sahara and Namib deserts. In north western Europe, drizzle and rain is generally spread quite evenly across the year, as anyone who has gone camping in British summer will tell you. But when annual rainfall happens within just a few months or weeks of the year then it is a massive challenge for farmers, towns and industry to access enough water through long dry seasons and to protect themselves and their land from flooding and mudslides when the rains come.
New research suggests that Africa’s aquifers could be the key to managing water better. Professor Richard Taylor at UCL explains: “What we found is that groundwater in tropical regions – and Sub-Saharan Africa in particular – is primarily replenished from intense rainfall events – heavy downpours. This means that aquifers are an essential way of storing the heavy rain from the rainy season for use during the dry season, and for keeping rivers flowing.”

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters.

The GroFutures team is working with the Tanzanian Ministry of Water to establish automated, high-frequency monitoring to examine how heavy rains associated with the El Niño Southern Oscillation (ENSO) replenish vital groundwater resources.
The team from Sokoine University of Agriculture (Japhet Kashaigili, PhD student Richard Festo) and UCL (Richard Taylor, PhD Student David Seddon) are working with the WamiRuvu Basin Water Office in a small semi-arid basin (Makutapora) in central Tanzania which features a wellfield that supplies the capital city, Dodoma, with safe water. Groundwater withdrawals have risen sharply in recent years and there is considerable uncertainty regarding the sustainability of this supply. Previous research led by members of the GroFutures Team showed that replenishment occurs episodically, on average just 1 year in 5, and usually in association with El Niño events.
In anticipation of the “Godzilla” El Niño event this year, the team is setting up instruments to monitor hourly groundwater levels and river stage (level) to investigate how heavy rains replenish groundwater at the Makutapora Wellfield. These observations will inform not only sustainable management of wellfield itself but also strategies for amplifying replenishment here and in other similar tropical semi-arid locations.
