Planned Impact
GroFutures will benefit: (1) poor water users (women and men, rural and urban) in Sub-Saharan Africa (SSA) through increased knowledge and evidence of sustainable groundwater use to alleviate poverty through improved resource management and enhanced health and livelihoods; (2) water planners and policy makers in SSA through the development of new evidence and methodologies to enable equitable and sustainable management of groundwater resources; and (3) research communities in SSA and beyond through creating improved new tools, methods and datasets for interdisciplinary analysis of groundwater resources and their management, as well as scholarly information exchanges and networking activities that will strengthen a growing Community of Practice involving Anglophone and Francophone scientists.
The primary pathway by which GroFutures will generate impacts for poor people is through the development of new evidence and tools which water managers in the focal countries and across SSA can use to: (1) target groundwater development where it can most effectively reduce poverty; and (2) ensure equitable and sustainable development of groundwater resources.
GroFutures will contribute to unlocking the poverty-reducing potential of groundwater in SSA by:
1) Establishing a unique Network of African Groundwater Observatories (NAGO) that will generate new evidence on groundwater availability and demand, including insights into how these are likely to change over the next two to three decades giving planners at basin, national and regional levels the information they need to plan for an equitable and sustainable allocation of groundwater for multiple users and uses;
2) Identifying locations in which groundwater development (for domestic supply or irrigation) is a technically appropriate and politically feasible strategy to reduce poverty;
3) Identifying locations at risk of future depletion due to likely demand/supply imbalances enabling appropriate management responses to be developed on a preventive rather than curative basis;
4) Providing specific information on variations in groundwater availability and demand which can carry high costs for economies and for the livelihoods of poor people and make planning and management difficult;
5) Strengthening the capacity of water planners, researchers and their institutions through the co-production of knowledge and collaborative, demand-led research and stakeholder engagement;
6) Identifying governance arrangements for pro-poor, sustainable groundwater management, in collaboration with water managers and other key stakeholders; and
7) Disseminating new evidence and knowledge on the positive outcomes of groundwater development for health and livelihoods enabling poverty alleviation.
The GroFutures team will engage staff of national, regional and local water bureaux in Ethiopia, Niger and Tanzania, as well as basin authorities (Great Ruaha, Niger) as project partners from the start in the research planning, data analysis and tool/metric development and piloting. They will also embed new scientific knowledge, models and methods for managing groundwater for poverty alleviation within water ministries to inform decision-making and initiate discussions about equity in groundwater development among relevant stakeholders.
Production and dissemination of high quality, open-source publications - in the form of academic outputs in high impact journals, as well as targeted policy briefs and other bespoke communications materials suited to different audiences - will be a central aim of the project. These will involve all members of the team and will be published in English, as well as French, Amharic, Hausa and Kiswahili, where appropriate. All materials and information will be accessible via a dedicated, bilingual website (grofutures.org) that is linked to institutional websites of the project team (AAU, BGS, IDS-STEPS, IGRAC, IRD, IWMI, SUA, UAM, UCL, UoS) and the UPGro Knowledge Broker.

Description | GroFutures research derived from inter-disciplinary research in three basins in each of Tanzania, Ethiopia and Niger found: (1) substantial increases in urban and irrigated-land areas have occurred at the expense of natural land cover; (2) access to groundwater for productive purposes is associated with improved agricultural production, reduced agricultural risk, and increased household income; and (3) stakeholders expressed a strong preference for small to medium-scale, multi-purpose groundwater development pathways that are managed municipally and a strong aversion to large-scale groundwater development pathways due largely to concerns of environmental impact and equity. GroFutures also led a pan-African analysis of long-term piezometric records under conditions of varying aridity across 9 countries in tropical Africa that revealed a bias in groundwater replenishment to heavy rainfalls that is most pronounced in drylands and is often predictable, associated with large-scale controls on climate variability such as El Niño. Further the research highlighted the importance of focused recharge pathways in replenishing aquifers in drylands, a process that is not represented in hydrological models estimating recharge and the impacts of climate change on groundwater recharge. Detailed field research in a semi-arid environment, the Makutapora Wellfield supplying Tanzania's capital city, Dodoma, shows that groundwater replenishment is episodic, occurring primarily during heavy rain events associated with El Nino; this replenishment results primarily via leakage from ephemeral stream discharge. |
Exploitation Route | GroFutures research showing access to groundwater for productive purposes is associated with improved agricultural production and increased household income is being taken forward by AMCOW (African Ministerial Council on Water) as well as national governments to promote groundwater use to alleviate poverty and realise UN Sustainable Development Goals. Further, GroFutures research revealing a bias in groundwater replenishment to heavy rainfalls across tropical Africa, expected to increase under global warming, is being taken up through climate change adaptation plans as use of groundwater may prove a logical adaptation to climate change and projected increases in freshwater withdrawals for drinking water and irrigation. Research under GroFutures at the Makutapora Wellfield supplying Tanzania's capital city, Dodoma, shows that groundwater replenishment is episodic and occurs primarily during heavy rain events associated with El Niño events. Further, field research also shows that it occurs primarily via leakage from ephemeral stream discharge associated with heavy rainfall events. As a consequence of this research, the Government of Tanzania with support from The World Bank has issued a tender for the development plans to explore the feasibility of enhancing wellfield replenishment through Managed Aquifer Recharge in order to improve the capacity and resilience of Dodoma's water supply. |

Results and Impact | GroFutures researchers have engaged with groundwater users in Ethiopia, Niger and Tanzania in 2017 and 2018 through the implementation a common survey instrument. In the Iullemmeden Basin in Nigeria and Niger, the Upper Awash Basin in Ethiopia, and the Great Ruaha Sub-Catchment in southern Tanzania, GroFutures researchers have been polling groundwater users' views on small-scale, household-level use of groundwater for irrigation, the status of groundwater governance, and their experiences of different irrigation, pump, conveyance and application technologies. This research activity addresses a critical lack of detailed information regarding not only groundwater use and dependence but also governance arrangements as experienced at the household level. In the Upper Awash Basin, the GroFutures team working alongside the Oromia Irrigation Development Authority has recently completed a survey of 400 households, representing 30% of the population from predominantly agricultural communities within the Becho and Koka Plains at Alango Tulu and Dungigi-Bekele. In the Great Ruaha Sub-Catchment, the survey has been trialled with user communities in Chimala and Mbarali as well as the Maradi and Gaya areas of Niger. Results from the surveys will inform scenarios being co-created by GroFutures researchers, groundwater users and other stakeholders to inform an inclusive an participatory Pathways Approach in which groundwater users and other stakeholders will develop their own criteria for evaluating different groundwater development pathways for which the physical sustainability is determined by models developed using evidence from local observatories recently established under GroFutures. |

Results and Impact | The UPGro programme, supported by AfriWatSan & ESPRC, conducted a pan-African capacity-strengthening and knowledge co-production workshop at Sokoine University of Agriculture in Morogoro, Tanzania from the 10th to 12th of February, 2017. 40 participants from 12 countries in Africa took part and analysed multi-decadal, groundwater-level data ("chronicles") from 9 countries including Benin, Burkina Faso, Ghana, Niger, Sénégal, South Africa, Tanzania, Uganda and Zimbabwe. Participants comprised PhD students and more experienced researchers (mentors & supervisors) as well as representatives from government ministries and the private sector, and included team members from all 5 UPGro consortium projects GroFutures, BRAVE, Hidden Crisis, GroForGood, and T-Group. Training focused on the application of the water table fluctuation method for analysing groundwater-level records and was led by GroFutures and The Chronicles Consortium, an international consortium of scientists from across Africa and beyond collating and analysing multi-decadal records of groundwater levels in order to assess the impacts of groundwater use, climate variability and change, and land-use change on groundwater storage across Africa. In addition to addressing key capacity-strengthening goals, the workshop provided a platform for the co-production of knowledge. As a result, a collaborative, pan-African analysis of multi-decadal groundwater-level records is in preparation and a number of participants is expected to contribute their national-scale analyses to an upcoming special section of Hydrogeology Journal. |
