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.

“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.

Multiple actions have been developed by community members in Kampala to address their sustainability problems

by Giorgia Silvestri re-posted from T-group.science

At the end of October 2018 the local transition team in Kampala has been very active organizing three ‘agenda setting’ transition arena meetings with participants from multiple communities (such as Makerere, Mukubira, Bwaise and Kawaala) in informal settlements in Kampala. The meetings aimed at supporting participants to develop short, medium and long term actions that would address the already identified local problems.

The local transition teams started the arena meetings by sharing some of the most important insights from previous meetings such as the vision narratives previously developed by the participants. The back-casting methodology was then used to support the participants to identify short, medium and long term actions.


Figure 1. A group of participants Kawaala community during the back-casting exercise

The majority of the short-term actions developed by the participants were associated to educational and awareness raising activities related to water, sanitation and waste management. Some groups of participants discussed how to teach community members correct hygiene practices, proper construction of toilet facilities and practices of maintenance and protection of water sources. In one of the groups in Makerere and Mukubira zones, participants discussed to run a water harvesting plan at household level and to start lobbying with institutions like KCCA and NWSC to increase sensitization activities at community level related to water and sanitation best practices.

During the meeting with participants from Makerere and Mukubira zones, one of the developed long term actions consisted of creating a rewarding system for individuals who would carry on good practices in protecting and preserving water sources.

Other major actions developed in all organized meetings were related to ensure the enforcement of laws related to water, waste and sanitation management. In Bwaise, for example, the implementation of fines related to poor toilet usage and construction were discussed.  

Additionally, participants in all areas spoke about the importance of mobilizing community members and setting up active groups aiming to carry on sensitization activities and to ensure the maintenance of services over time. For example, in Makerere and Mukubira zones, one group of participants would like to form a water committee, while in Bwaise zone the group of participants focusing on the problem of sanitation had the idea to form community led groups to prevent unplanned toilet construction.

Other important actions included the creation of Savings and Credit Cooperatives (SACCOs) for supporting the local circular economy by producing products from waste materials.


Figure 2. A group of participants from Makerere and Mukubira zones are brainstorming about the actions to be developed in their communities.

The results of the ‘agenda setting’ arena meetings show that the implementation of facilities and services alone do not contribute to solve local water, sanitation and waste management problems. Rather, a combination of actions is needed for addressing the rooted and interlinked problems. New organizational and governance capacities at both community and institutional level need to be developed in order to ensure the maintenance of facilities over time. The change of practices and behaviors related to water, sanitation and waste management need to be constantly supported by organizing awareness raising and education activities, by mobilizing and empowering community members, such as through active groups as well as by ensuring the reinforcement of laws. The collaboration and dialogue between local community members, institutional organisations, NGOs and private companies play a key role in the implementation of these actions and will be further explored in the next meetings taking place in January.

How are multiple actors identifying and discussing the main problems affecting their community? Insights from the Transition Management process in Kawala community, Kampala (Uganda)

Sixteen participants belonging to Kawaala community participated in the first Transition Management arena with the aim to define the most urgent and priority problems in their communities. The participants arrived on time and shared since the beginning of the meeting their motivation to participate. Most of the participants already knew the T-GroUP research team since it has been disseminating its research findings in the community and some researchers participated in some of the meetings organized at community level. The dissemination of information and the continuous engagement of the researchers at community level played a key role in building trust with the community residents and in creating a comfortable atmosphere during the Transition Arena meeting. After an introduction given by the local team coordinator Prof. Robinah Kulabako, the participants discussed in two groups the most important problems in Kawala community.

TGroup1
Figure 1. Participants of the TM arena meeting working in groups.

Participants voiced the following as the main challenges affecting their community: lack of water supply, insecurity, inadequate sanitation facilities, poor infrastructures (e.g. roads and houses), contamination and scarcity of water, unemployment and poor waste management services. Then, participants in each group were invited to discuss the causes of these problems as well as the reasons of persistence. Multiple causes of the problems described above were discussed, such as the low awareness of the residents on how to build proper sanitation facilities or how to collect waste, the corruption and political tensions in the different sectors, and the lack of consultation and participation of local residents in decision-making processes run by local authorities. A representative from each group very enthusiastically presented the main points discussed in their group, as shown in the following picture.

The other participants actively participated in this last part of the meeting by asking questions, sharing their point of view and adding other examples connected to their experiences. One of the highlight of the meeting is that political tensions should be taken into account in the multi-stakeholder process because they are one of the causes of failure of many projects and initiatives in Kampala. The engagement, participation and collaboration with local authorities like Kampala Capital City Authority (KCCA) and public utility companies like the National Water and Sewerage Corporation (NWSC) is key for the development of new practices, cultures and policies related to water, sanitation and waste management. Additionally, the unsustainable behavior and practices of local residents regarding water, waste and sanitation management needs to be taken into account and innovative ways of engaging and sensitizing citizens need to be explored.
