UPGro T-Group research finds cancer-causing viruses in Kampala and Arusha slum groundwater

by Isaiah Esipisu and Dr Jan Willem Foppen (T-GroUP)

In Summary

  • The study found that most groundwater in the two slums contains traces of herpes virus, poxvirus and papilloma virus.
  • Cancer is one of the top killer diseases in East Africa, blamed for nearly 100,000 deaths every year.

Researchers from IHE Delft Institute for Water Education and their peers from Uganda and Tanzania have found traces of 25 DNA virus families — some of them with adverse health risk for humans — in underground water in the slums of Kampala and Arusha.

The study, whose findings were presented at the Assembly of the European Geosciences Union in Vienna on Monday, found that most groundwater in the two slums contains traces of herpes virus, poxvirus and papilloma virus.

CANCER

The latter could be one of the causes of cancer in East Africa.

“These viruses have never been found on such a large scale in ground water. Perhaps it is because there has never been an in-depth analysis,” said Dr Jan Willem Foppen, one of the lead researchers and a hydrologist at the IHE Delft — the largest graduate water education institution on the planet.

Cancer is one of the top killer diseases in East Africa, blamed for nearly 100,000 deaths every year.

According to the latest report by the International Agency for Research on Cancer, some 32,617 new cases were reported in Uganda last year, with 21,829 deaths.

32,617 DEATHS

In the same period, Kenya recorded 47,887 new cases and 32,987 deaths while there were 42,060 new cases in Tanzania with 28,610 deaths.

Scientists have therefore expressed concerns that the widespread use of groundwater in slums for cooking, cleaning and bathing poses a risk for the residents.

In the two-year study, the scientists analysed surface water (river and drain), spring water, wells and piezometers (groundwater from specific depth) in the three countries.

“We found 25 DNA virus families, of which 14 are from above ground hosts like frogs, mice, rats, cows, horses, monkeys and humans,” Dr Foppen said.

DISEASES

Of the human disease causing pathogens found in the samples, herpes virus and poxviruses can lead to skin infections while the papilloma cause some types of cancers such as cervical, laryngeal and mouth.

“This could be just a tip of the iceberg. We have not found all the viruses. We found the most abundant ones,” Dr Fopen said.

“Let’s do something about sanitation. Let us improve our sources of drinking water and identify new pathways with communities towards sustainability.”

New state-of-the-art research collection on groundwater sustainability across Sub-Saharan Africa

An important new collection of papers has just been published online in the Hydrogeology Journal:

Substantial increases in groundwater withdrawals are expected across Sub-Saharan Africa to help nations increase access to safe water and to amplify agricultural production in pursuit of UN SDG 2 and SDG 6.  Long-term groundwater-level records or chronicles play an important role in developing an improved understanding of the hydrogeological and climatic conditions that control access and sustain well yields, informing where, when and how groundwater withdrawals can sustainably contribute to building resilience and alleviating poverty.

There are four papers in the collection (and an overview essay) that provide a sample of the new research outputs emanating from The Chronicles Consortium and UPGro GroFutures:

  • Evidence from chronicles in seasonally humid Benin and Uganda show annual cycles of replenishment from direct, diffuse recharge generated preferentially by heavy rainfalls. Kotchoni et al. show how chronicles from different geological environments in Benin can be modelled very effectively on a daily timestep with an improved watertable fluctuation model.
  • In semi-arid southwestern Niger, chronicles show that recharge to weathered crystalline rock aquifer systems occurs directly from rainfall but is restricted by a thick clayey aquitard developed from schist. However, greater recharge is shown to occur indirectly via riverbeds of ephemeral streams which provide preferential pathways through the saprolite.
  • Evidence from the Makutapora Wellfield of semi-arid central Tanzania that groundwater, abstracted at rates exceeding 30,000 m3/day, is sustained by episodic recharge associated with El Niño Southern Oscillation (ENSO). Further, abstracted groundwater is partially modern, derived from rainfall within the last 10–60 years.
  • Studies from Benin and Niger highlight the low storage of weathered crystalline rock aquifers and the importance of modern recharge in sustaining groundwater use. The low storage and low but highly variable hydraulic conductivity of weathered and fractured crystalline rock aquifers found over more than 40% of Sub-Saharan Africa may, however, have a potential advantage. Such aquifer systems restrict opportunities for intensive and competitive abstraction and are thus potentially self-regulating. Low-intensity groundwater abstraction distributed across the landscape also complements existing land-tenure systems in many areas of Sub-Saharan Africa dominated by smallholder agriculturalists.
  • The chronicles provide invaluable datasets to help direct assessments of past impacts of climate variability—e.g. ENSO, Atlantic Multi-decadal Oscillation (AMO)— and abstraction on groundwater storage. Such records, when continuously updated, can also provide key input to water resources management by tracking emerging risks to water security from groundwater storage decline or groundwater flooding (e.g. Murray et al. 2018).
  • Regional-scale (>50,000 km2) networks of long-term piezometric records can also be used to test the reliability of largescale, satellite observations from the Gravity Anomaly and Climate Experiment (GRACE). Indeed, the emergence of GRACE measurements of changes in total terrestrial water storage adds a potential tool, albeit at a much larger scale (>200,000 km2), to estimate changes in groundwater storage where records do not exist. However, there are substantial uncertainties from such estimates.

3 new UPGro papers + Groundwater to be the UN-Water theme for 2022

We are delighted to report that UN-Water, the coordinating body for water issues across the United Nations, in a meeting this week agreed to make the theme of the 2022 World Water Development Report and World Water Day: “Groundwater: making the invisible visible” http://enb.iisd.org/water/un/30/html/enbplus82num34e.html

Meanwhile three new UPGro papers have recently been published:

“Groundwater hydrodynamics of an Eastern Africa coastal aquifer, including La Niña 2016–17 drought”

Núria Ferrera; Albert Folch; Mike Lane; Daniel Olago; JuliusOdida; Emilio Custodio  (Gro for GooD)

Key Points

  • The recharge was reduced 69% compared to average annual rainfall.
  • Lower recharge during first and nil recharge during the second wet season
  • No important groundwater quality changes observed inland
  • Increase of seawater intrusion even during the wet season

“A case for urban liveability from below: exploring the politics of water and land access for greater liveability in Kampala, Uganda”

Maryam Nastar, Jennifer Isoke, Robinah Kulabako & Giorgia Silvestri (T-GroUP) https://www.tandfonline.com/doi/full/10.1080/13549839.2019.1572728

Key Points

  • Despite efforts of local governments and NGOs to put public service delivery systems in place, there is a gap between goals and actual impacts on citizens’ quality of life
  • Decentralisation has faced challenges from the emergence of national partisan political struggles in local areas.
  • Pre-paid standpipes were installed with magnetic charge cards handed out for free. Initially a UGX25 card top-up bought 4 jerry cans (20l), overtime this reduced to 3 jerry cans. If a card was lost or stolen then a replacement cost users UGX15,000-25,000, which was unaffordable to many slum dwellers who then bought water from the standpipe caretakers for UGX 100-250/jerry can. Intermittent water supply from pre-paid meters is another factor making residents seek alternative water sources – generally unsafe springs, or from vendors and resellers at UGX 200-1,000 per jerry can.
  • Water is just one problem for residents – access roads, waste disposal, expensive school fees and high youth unemployment also mentioned in interviews.
  • Local elections have not happened as mandated because the government fears they will lead to social unrest. This has contribute to resident distrust of local government. 
  • Land ownership is a major barrier to water access and sustainability: there are no clear land records and there are many layers of complexity involving landlords, tenants, the city and traditional authorities.  Changing the land title from private to communal for WASH facilities is essential.
  • Political parties do sometimes co-opt community leaders and demobilise communities, but they can also create political spaces for debate on governance, rules and policies.
  • Strong social capital/networks and trust can help mobilise community power and resources, but can exclude some residents from decision-making processes.
  • NGOs, universities and social movements can play a crucial role in magnifying the ability of communities to act together and achieve liveability goals.

Transition Management for Improving the Sustainability of WASH Services in Informal Settlements in Sub-Saharan Africa—An Exploration. 

Silvestri, G.; Wittmayer, J.M.; Schipper, K.; Kulabako, R.; Oduro-Kwarteng, S.; Nyenje, P.; Komakech, H.; Van Raak, R. (T-GroUP) https://www.mdpi.com/2071-1050/10/11/4052

Key points:

  • “Transition Management” is a participatory planning technique developed for addressing sustainability issues in Europe. The UPGro T-GroUP project is one of the few examples of trying to apply the method in another context: Kampala (Uganda), Arusha (Tanzania), Dodowa (Ghana).
  • The authors identify five contextual factors that account for unsustainable WASH services:
    • Access to water and sanitation in informal settlements comprises a mosaic of formal and informal practices, water sources, sanitation facilities, behaviours and actors.
    • Fragmented and low governance capacity. Low levels of trust between actors.
    • Landownership: unequal and skewed. In Kampala, water and sanitation projects failed due to land conflict; landowners ‘donated’ land for the facilities but after some years later they would take back possession of the land and deny access to the facilities without paying.
    • Public participation in general and WASH services in particular:  more vulnerable community members are excluded
    • Unequal access to WASH services, for example water price varying on social status, with women being disproportionately disadvantaged. Low access to education plays a crucial role.
  • Transition Management was developed based on liberal representative democracies, but this experience in Sub-Saharan Africa suggests that here it needs to be about enlarging and strengthening democratic space  – as a method it is not neutral or universal but shaped by cultural norms and expectations.

:: New UPGro Paper :: Understanding process, power, and meaning in adaptive governance

Two new social science papers from Hidden Crisis

Key Points from :

Understanding process, power, and meaning in adaptive governance: a critical institutional reading.

  • “Adaptive governance” has a number of core principles:
    • The need to live with change and uncertainty
    • To foster adaptive capacity (i.e. being able to anticipate and respond to change and uncertainty)
    • To understand human and natural systems as interconnected
    • To consider resilience as the central desirable attribute, e
  • One of two case studies focuses on a non-UPGro project, called SWAUM (2011-2016), in the Great Ruaha River catchment in Tanzania (which, by coincidence is one of the GroFutures observatories)
    • Concerns about the catchment arose in the 1990s and a number of donor-funded projects tried to improve the natural/water resource management of the catchment.
    • An evaluation of the SWAUM project had strengthened coordination both vertically and horizontally through hierarchies at different political levels.
    • Limited improvements in land management had taken place but despite the greater awareness, debate and agreement, local people continued to cultivate river banks and river beds to the detriment of the river flows – and despite a deliberate attempt to include marginalised people, they did not get significant representation from pastoralists. This may be in part due to a dominant narrative from other, more powerful, stakeholders that they are to blame for resource depletion.
  • Cleaver and Whaley conclude that the following three elements are inextricably bound together:
    • Process: institutions that are designed for adaptive governance (such as knowledge sharing platforms, resource management arrangements) may only work and endure where they serve other socially valued processes and are embedded in accepted forms of behaviour and practices.
    • Power: allocation or resources or dominance of particular narratives about cause-and-effect is driven by visible, hidden and invisible uses of power by individuals, social groups and organisations. This is often why designed interventions for adaptive governance often deliver less than expected.
    • Meaning: There different worldviews on cause and effect in the human and natural worlds and involve multiple processes that will likely affect adaptive governance arrangements.

Water monitoring upgraded in Upper Great Ruaha, Tanzania

re-posted from GroFutures

The GroFutures Team, working with the Tanzanian Ministry of Water and Irrigation, expanded monitoring infrastructure in the Upper Great Ruaha Observatory (UGRO) to include interactions between groundwater and surface water.

An outstanding question regarding the sustainability of groundwater withdrawals for irrigation and drinking-water supplies is whether groundwater in the agriculturally intensive lowlands is replenished by river flow, sustains river flow, or both depending upon the season.

Life after UPGro: an interview with Early Career Researcher, Shabana Abbas

SHABANA-3The UPGro programme is an amazing opportunity for young researchers to get experience at the cutting edge of interdisciplinary research that is focused on tackling poverty.

We caught up with Shabana Abbas, who was part of the T-GroUP project and is second author on a new UPGro paper entitled:The emancipatory promise of participatory water governance for the urban poor: Reflections on the transition management approach in the cities of Dodowa, Ghana and Arusha, Tanzania.

UPGro: Where are you from and how did you get involved in UPGro?

SA: I am from Pakistan. I got involved in UPGro in 2015, when I was pursuing my MSc at IHE Delft Institute for Water Education in the Netherlands.

UPGro: What research activities did you do as part of the T-GroUP project?

SA: I was offered the opportunity to undertake my masters research under the T-GroUP project, one of the consortium projects of UPGro. My research was about urban water supply and groundwater governance in Arusha city in Tanzania. I took a multi-scale approach and collected mostly qualitative data through in-depth interviews at ward, city and at the basin level.

Some of the key actors that I interviewed were residents from six different wards (lowest administration units within the city), Ward administrators, employees of the Arusha Urban Water Supply and Sanitation Authority, Arusha City Council and of the Pangani Basin Water Board. I also interviewed selected industrial/commercial users of groundwater such as bottled water companies, breweries etc. Moreover, I interviewed drilling companies operating in the city.

Through all my research activities including document analysis, I aimed to understand who is using groundwater, where, why and what does it say about the overall use of groundwater in Arusha. I tried to explore how this use is governed (if) for both environmental and social needs.

UPGro: What were your highlights of being part of the UPGro programme?

SA: For me there were three things:

Firstly, the opportunity to collaborate with researchers from different institutes/universities such as the team at IHE Delft, Netherlands, Dr. Maryam Nastar (Lund University, Sweden) & Dr. Hans Komakech (Nelson Mandela Institute, Arusha, Tanzania), who are all part of the T-GroUP.

Secondly, the entire experience of living in Arusha for three months with two other IHE students, also working under the project. All three of us looked at different aspects of groundwater in Arusha. I enjoyed the process of finding out new details every day and discussing/comparing these with the fellow researchers.

Finally,  the chance to work with Dr. Michelle Kooy & Dr. Margreet Zwarteveen, my supervisors who have inspired me and supported me throughout my research.

UPGro:  What did you take away about the links between groundwater use (or lack of it) and poverty? 

SA: There are two sides to it:

Firstly, most of the boreholes and wells in the areas I visited were mostly owned by people from higher socio-economic class and that prices that they charged to other households (mostly to ones who could not afford to have their own wells and boreholes) varied and were unregulated.  This makes me wonder if groundwater is really for the urban poor if they have to spend quite some amount on it?

Secondly, I found the higher concentration of fluoride in groundwater in Arusha limits its use for non-potable uses only. This means that if groundwater supplied at fair price to the poor can actually lessen their overall expenses on water. . I learned that groundwater plays a big role in the different household water supply combinations. For instance, in the six different areas of the city, people (both from high and low socio-economicbackground) used 28 different household water supply combinations and about 50% of these included water from boreholes and wells.

UPGro: What did you do next, and where are you now?

SA: After graduation, I joined Aqua for All in the Hague, Netherlands. Here, I work on a water innovation programme (VIA Water) that supports innovations addressing urban water & sanitation challenges in seven countries in Africa. One of the key areas of innovation that we support is for ‘sustainable use of groundwater resources’ and we have some interesting innovations being piloted in these countries. You can find out more about these projects here: www.viawater.nl/projects

Then in my spare time (!) I am President of the Water Youth Network and lead the Advisory Board. I am also one of the Junior Global Advisory Panel members for Oxford University’s REACH programme.

UPGro: How did being part of the UPGro T-GroUP project help you, or steer you in new directions?

SA:  Prior to my masters, I worked on rural water supply projects in the north of Pakistan. There, water was mostly sourced from springs. Participation in T-GroUP allowed me for the first time to study groundwater in detail. I was able to see what groundwater means for urban water supply in Arusha and in other African cities.It was all very new for me. I was quickly able to find out how serious the issue of groundwater governance is in many developing countries.  My research in Arusha made me very curious and interested in water issues in Africa. It also motivated me to take on the job I am doing at the moment.

UPGro: What advice would you give to other young people who would like to get involved in African water issues?

SA: Go out there with an open mind; Don’t be afraid to ask the ‘why?’ questions and remain critical.

UPGro: What can programmes like UPGro do to support young researchers and young professionals in their careers?

SA: Offer more opportunities to young researchers to share their  work through webinars and other mediums. Moreover, after students finish their research work, offer them some sort of fellowship for translating their work into knowledge products for wider/non-academic audiences.

UPGro:  Finally, what changes would you like to see in the way that groundwater is managed across Africa?

SA: First, I would like that groundwater be recognized as an essential resource that needs to be governed in a socially equitable and ecologically sustainable way.

And second, I would like that local actors take responsibility of ensuring that groundwater is not overexploited. They should make efforts to utilize the UPGro/other research work and see how policy level changes on groundwater can be informed by that.

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.
