:: New UPGro paper :: Participatory scenario analysis for urban water and sanitation: Kisumu, Kenya case study

Posted on by RWSN Secretariat

“A participatory methodology for future scenario analysis of sub-national water and sanitation access: case study of Kisumu, Kenya” by Heather Price, Lorna. G. Okotto, Joseph Okotto-Okotto, Steve Pedley & Jim Wright: https://doi.org/10.1080/02508060.2018.1500343 from the UPGro Catalyst Project “Sustaining groundwater safety in peri-urban areas”

Context:

  • Many cities in Sub-Saharan Africa, and other low and middle income countries, are growing fast. Expansion of water supply systems to meet that growing demand is challenging, particularly in the context of climate change and competing water uses, such as agriculture.
  • Scenario planning, with geographical information systems, is an essential tool to help government bodies and utilities plan investments in urban and peri-urban water supply infrastructure and services, but examples in developing countries remain rare and have generally been rural.
  • The case study, Kisumu, is a city in Western Kenya near the shores of Lake Victoria. The Kisumu Water and Sewerage Company (KIWASCO) has responsibility across the city.

Key Points:

  • 12 key informants with particular insights into the water and sanitation sector, social and economic planning and human population dynamics were identified and included in two sessions: (1) Background information and future trajectories of population growth; (2) computer software called “International Futures” was used to explore different population scenarios, which formed the basis of discussions on water and sanitation planning for the city in three groups.
  • Through the participatory planning in separate groups it was possible to draw out where areas of consensus and uncertainty about how the city, and its demand for water and sanitation will change. One area of common agreement was that groundwater and on-site sanitation will remain an important part of the mix until at least 2030, which implies and longer-term need for interventions like household filters, chlorine dispensers at well heads, education or land tenure reforms to enable sewerage installation.
  • Future research should focus on a broader range of scenarios than just extending current trends in population change, for example: ethnic conflict, social fragmentation, and rapid, Chinese-led infrastructure development.

:: New UPGro Paper :: Tryptophan-like fluorescence as a measure of microbial contamination

Posted on by RWSN Secretariat

A new paper has been published from the UPGro Gro for GooD project, working in Kenya, which develops the work done under the UPGro Catalyst Project on mapping groundwater quality, which developed an exciting new low-cost, real-time method of measuring microbial contamination of groundwater.

Context:

  • Globally, 25% of people lack access to water that is free from microbial contamination, in some countries the proportion is much higher.  This has major health implications, particularly for children.
  • Monitoring water quality for disease-causing organisms is difficult, and the common method is take water samples to a lab to measure Coli bacteria. Although largely successful, it is an expensive in terms of time and materials, and cannot be relied on for some kinds of biological water quality risks – particularly in groundwater where the absence of E.Coli does not guarantee biological safety of the water.
  • Tryptophan-like fluorescence (TLF) is a relatively new way of rapidly measuring biological water quality in the field, without needing expensive and time-consuming lab equipment and consumables. It is better suited to groundwater than surface water monitoring.

Key Points: –

  • This is the first groundwater study to compare TLF with E. Coli specifically.
  • Tryptophan-like fluorescence (TLF) can complement E. coli as a risk indicator, but it is not proposed as a replacement.
  • Both TLF and coli distinguish low/intermediate, high and very high risk sources.
  • TLF has negligible variability due to the method, unlike bacteriological analyses.
  • TLF is useful for pre-screening, monitoring and demonstrating risk in groundwater.
  • Fieldwork for this research was done in rural Kwale Country, Kenya
  • Next steps include:
    • focus on how TLF relates to pathogens and health, rather than just focusing on the coincidence with E.Coli.
    • better understanding of TLF in different groundwater conditions
    • better computer software of processing and presenting TLF data
    • assess the usefulness of TLF in communicating water risks to groundwater users.

Young scientist seeks to understand link between access to groundwater and poverty

Posted on by nataliagutierrezc

Interview by Isaiah Esipisu, PAMAC news agency http://www.pamacc.org

Jacob Katuva is a doctoral researcher at the University of Oxford’s School of Geography and Environment.  His research focuses on community groundwater access and poverty in Kenya. Katuva holds a M.Sc. in Environmental and Biosystems Engineering from the University of Nairobi and a B.Sc. in Water and Environmental Engineering from Jomo Kenyatta University of Agriculture and Technology.

Previously, the scientist spent over four years working as a consultant in engineering and development in the Eastern Africa region. He has vast experience in design-construction-operation and management of community rural water supply schemes, hydrological analyses, rainfall-runoff modelling and water balance models.

His experience in water resources management covers water resources assessments, developing and linking Management Information Systems (MIS) and Geographical Information Systems (GIS) and advanced geo-statistics to water resources planning and management as well as hydropower feasibility studies, evaluation and impact studies of WASH programs, rural water supply and pollution studies in the context of the mining, irrigation and the water sectors in rural Kenya.

Q. How did you get involved with the UPGro project?

I joined UPGro back in 2013 when I was consulting with Rural Focus Ltd during the implementation of the catalyst project led by Oxford University. I was heavily involved in the set-up of the environmental monitoring network and the socio-economic surveys. This provided a great deal of natural and social science data regarding groundwater level and quality, water usage, health and welfare indicators paving way for an interdisciplinary study. I ended up applying for the D.Phil. programme at Oxford University to research groundwater and poverty in sub-Saharan Africa with a particular focus on coastal Kenya. I was fortunate to obtain additional funding from Base Titanium, a mining company working in Kenya which is one of the partners in Oxford University’s UPGro consortium project Gro for GooD.

Q. Tell us about your studies at the Oxford University and how it relates to the UPGro project

My research at Oxford University explores the links between groundwater and poverty. Understanding groundwater and poverty linkages is critical to unlocking the potential of groundwater for poverty reduction. Central to accelerating and sustaining Africa’s development is improving the understanding of how improved access to groundwater resources can benefit the poor. This includes identifying the role of groundwater on productive uses such as livestock watering and crop irrigation, examining the relationship between poverty and changes in groundwater levels, and understanding how groundwater dependency and access to sufficient, affordable, reliable, safe, good quality water and physical access are linked to the socio-economic development of households. These dimensions are pertinent to policy and practice in poverty reduction.

Q. What are some of the early findings for your research?Nyumbasita Pump.jpg

There is evidence that the depth of boreholes and poverty are associated: We saw wealthier households being associated with deeper groundwater sources while poorer households were associated with shallower wells and boreholes. However, due to the cumulative nature of the volumetric data from the handpump water data transmitters (http://www.oxwater.uk/technology.html) we could not disassociate the handpump usage per household since the transmitter, similar to a water meter, recorded the volume abstracted for each handpump and not volume abstracted by each household.

Q. What kind of advice would you give to the County Government of Kwale about groundwater, given your experience so far?

The UPGro project has generated pertinent knowledge on water services delivery in Kwale County and has identified pathways to poverty reduction. Two of the preliminary findings in Kwale include the discovery of paleochannels in Msambweni, empirical evidence of the benefits of smart monitoring and privatized professional maintenance and repair services on rural water supply infrastructure.

This discovery of paleochannels by Professor Olago of the University of Nairobi and his team, can accelerate achieving universal and equitable access to safe drinking water services for the County population. County should invest time and resources in understanding this resource and how it can be exploited to meet the ever-growing water needs for the county.

The County government should embrace the professional maintenance and repair services on rural water supply infrastructure to ensure rural communities, health centres and school children enjoy equitable access to safe drinking water.

This model of maintaining rural water services has been developed and tested in Kwale and Kitui County with positive results. The model is called the FundiFix model and more details can be found here: https://reachwater.org.uk/wp-content/uploads/2016/11/Fundifix-booklet-WEB.pdf. To accelerate poverty reduction, the County government should ensure borehole drilling and equipping standards are adhered to, communities water infrastructure receive preventive maintenance and professionalized repair services to keep water flowing.

Q. What is your message to upcoming scientists who are interested in your area of specialization?

I would urge upcoming scientists in Kenya to progressively broaden their research to incorporate both the social and natural sciences. Integrating the two, thereby widening our understanding of the socio-ecological systems, will lead to the development of much more effective policies informed by the needs of the people.

Q. What are your future plans beyond the UPGro project?

Part of my future plans includes seeing the completion, implementation and operationalization of the findings of the UPGro project here in Kwale so that our groundwater resources can benefit everyone here, in particular the poor. In addition I will be excited to contribute to framing the poverty reduction policies and strategies for the County building on the evidence emerging from the longitudinal socio-economic studies over the last four years.Carrying water

Water Module - Student Resource
Water Module – Student Resource

The UPGro Gro for GooD project has been delivering a programme of engagement to teach young people in Kwale County about water science and management. Water Clubs at 3 secondary schools have been participating in field trips, practical activities, experiments and conducting their own group research projects. This outreach work aims to develop students’ research and communication skills and showcase career options in the water sector.

In the run up to World Water Day 2018, the Gro for GooD project was delighted to welcome Madam Bridget Wambua, Director of Education for Kwale County, Kenya, to provide opening remarks (extract above) at a special event to celebrate the success of the Schools Water Clubs supported by the project over the last year. As the event got going, students listened with great interest to the keynote speech by Prof. Dan Olago from the University of Nairobi, and then took to the stage themselves for a series of presentations about club activities including water quality testing of school waterpoints, the installation and use of rain-gauges on school grounds, and field trips to the Base Titanium mine to see how the mine manages and recycles water in its operation.

Video extract from Prof. Olago’s speech

Other students presented their own mini-research projects into topics such as water conservation in agriculture and strategies for keeping water safe to drink, and one group gave an excellent explanation of artesian wells based on an email exchange with Gro for GooD hydrogeologist Mike Lane.

Students also brought practical demonstrations and posters to show in the teabreak, including a solar still demonstration from a group of students who had just heard that they are through the local round and have been invited to show their improved solar still design at Kenya’s National Science Fair for schools.

Madame Wambua and Professor Dan Olago then presented the schools, water clubs and club patrons with certificates of appreciation for their hard work and dedication to water-related environmental education, and 2 laptops were given to each club. The laptops were provided by the UK charity IT Schools Africa and preloaded with water-related environmental education resources collated by the Gro for GooD team.

Students also received print copies of a newly published Water Module Student Resource which was developed by the Gro for GooD research team with input from students and teachers at the schools. Mr Joseph Kimtai, teacher and club patron at Kingwede Girls Secondary School, said,

“I find this module of activities about water so helpful to the students – it complements what we are teaching in class. It also encourages critical thinking and solving problems related to the environment which is in line with one of the competencies of the incoming competency-based curriculum for Kenyan schools.”

The resource has been published under a Creative Commons licence so that other educational programmes in Kenya can make use of the content.

Co-author of the Water Module, Nancy Gladstone, said:

“It has been a privilege to work with secondary school students in Kwale County and help to meet their really encouraging thirst for knowledge about water. Education has a vital role in achieving the Sustainable Development Goal for water and we are sure that many of these students will put their learning to good use at school and as they go on to jobs and further education.

“The Water Module event also provided us with an opportunity to thank the teachers, headteachers and local partner organisations such as Base Titanium and Rural Focus Ltd. who have all been critical to the success of the clubs this past year, and to contribute to discussions about building the water module into ongoing education programmes in Kwale County, both formal and informal, so as to reach more students and further enhance learning.”

Long lasting rural water supplies in tough environments: lessons from Kenya

Posted on by RWSN Secretariat

by Dr Tim Foster (from the Oxwater blog)

Having just published the fourth instalment in a series of papers examining rural supply sustainability on the south coast of Kenya, it is timely to reflect upon some of the common threads that emerge from these related but discrete studies. Throughout our investigations we have examined rural water sustainability – and the determinants thereof – from all sorts of angles, including repair time, household financial contributions, revenue collection longevity, water source preferences, and – most recently – operational lifespan.

Can road design boost water security in rural regions?

Posted on by RWSN Secretariat

re-posted from GRIPP

Roads for Water is integrating road construction and small water infrastructure to harvest rainwater from small catchments for productive use, while reducing road damage and simplifying road maintenance. Improving road drainage design is reducing soil erosion and increasing groundwater recharge. Furthermore, using roads for resource capture can prevent dangerous and inconvenient flooding, and in some cases pave the way for sand harvest and dune management, tree planting and protection of other natural resources.

Starting as an UPGro Catalyst Project, Roads for Water is now scaling up across Ethiopia, Kenya, Bangladesh, Malawi, Uganda and elsewhere with support from the Global Resilience Partnership (USAID, Rockefeller Foundation, SIDA and the Zurich Foundation) and the World Bank. The Roads for Water Learning Alliance was established to bring researchers, implementers, policy makers, trainers, donors and other stakeholders together to share knowledge and to support roadwork for natural resource management and climate resilience. The initiative recently received the second-place prize in the Zilient 2017 Resilience Awards.

MetaMeta and Mekelle University encourage those interested to become part of the learning alliance to contact MetaMeta at marta@metameta.nl

New UPGro paper: “Risk Factors associated with rural water supply: A 30-year retrospective study of handpumps on the south coast of Kenya”

Posted on by RWSN Secretariat

2018 promises to be really interesting one as the UPGro (Unlocking the Potential of Groundwater for the Poor) reaches maturity. There is already a lot published since 2014 (https://upgro.org/publications-papers/peer-reviewed-journal-papers/) and here is a new one, which will be of interest to RWSN members – as it has been written by active RWSN members:

“Risk Factors associated with rural water supply: A 30-year retrospective study of handpumps on the south coast of Kenya”

By Tim Foster, Juliet Willetts, Mike Lane, Patrick Thomson, Jacob Katuva, Rob Hope

Key Points

  • This paper build on previous handpump & water point functionality work done by RWSN, the UPGro Gro For GooD and UPGro Hidden Crisis projects and recent analysis by the University of North Carolina
  • Research focuses on 337 Afridev handpumps installed in Kwale County, Kenya, under a SIDA financed programme between 1983-1995 that were identified and mapped in 2013 (out of 559 recorded installations by the programme in that area).
  • 64% were still working after 25+ years
  • They conclude that risk of failure increases most significantly in relation to:
    • Salinity of the groundwater
    • Depth of the static groundwater level
    • When the water comes from an unconsolidated sand aquifers
    • Distance to spare parts suppliers

During 2017 UPGro Gro for GooD researcher, Prof John Gathenya, from Jomo Kenyatta University of Agriculture and Technology (JKUAT) in Nairobi (Kenya) was appointed  Senior Fellow at the School of Civil and  Environmental engineering of the Technical University (TU) Dresden.

Prof. Gathenya visited TU Dresden from 15-29 May and 29 October-11 November 2017. In the first visit, he was in a team of staff and PhD students from hisdepartment. He presented a case study on Sasumua Payments for ecosystem services project at the International Dresden Water, Soil and Waste Nexus Conference organized by UNU-FLORES and was also a panelist in one of the forums in the conference.   At the Institute of Soil Science and Site Ecology, Prof. Gathenya did presented in seminars and held meetings to advise PhD students.

During the second visit he participated in Centre for International Postgraduate Studies of Environmental Management – CIPSEM 72nd Soil & Land Resources International Course. He presented on Payments for Ecosystem services as a tool to catalyze adoption of sustainable land management.  He had meetings with some professors and university administration such Vice Rector for research and chair hydrosciences department.

Currently the institute of Soil Science and Site Ecology and his department area involved in a project on assessment of sediment deposits in reservoirs using multi-frequency echo-sounding techniques and some staff and PhD students are engaged and we hope to grow our collaboration by writing proposals to German and EU funding agencies. The Institute of Soil Science and Site Ecology has good experience setting and equipping field research sites for studies in soil and water management and Prof. Gathenya hopes to draw on this expertise in future especially in connection with our engagement with the Kenyan Upper Tana Water Fund Project.

Meeting Kenyan girls’ thirst for groundwater knowledge through ‘Water Clubs’

Posted on by RWSN Secretariat

by Nancy Gladstone and Saskia Nowicki, Gro for GooD project, November 2017

Red dye spreading through a model ‘aquifer’ helps girls from Kingwede School in Kwale County, Kenya understand how pollutants travel in groundwater. The students are part of a school water club supported by the Gro for GooD project in partnership with mining company Base Titanium Ltd. Maji (water in Swahili) clubs  at 3 secondary schools within the Gro for GooD study area are proving to be an effective outreach mechanism for the groundwater research project. Almost 100 students are involved and over half of them are girls. The focus is on learning through activities, which have included hands-on sessions about groundwater recharge, storage and pollution using aquifer kits; practical experiments using water quality tests to demonstrate simple water filters and safe water storage; installing and gathering data from rain gauges; and field trips to see industrial water use and borehole drilling.

We asked the girls at Kingwede Maji to write a short paragraph on why they signed up to the club. Their responses indicated just how aware they are of the problems associated with inadequate water management – the risk of disease, time-consuming treks to waterpoints, seasonal water scarcity — and just how motivated they are to find solutions.

“Where I live we have rivers and also other sources of water. Our water get polluted especially the river water mainly from animal waste. I am in this club so that I can know how to treat the water so that it can be safe for use.” Munirah R.

“I am so eager to know how that water from the river may reach nearer where we can easily get it. Reason being that from our homes to the river is quite a long distance and it usually takes us almost a whole day looking for the water. Which is time wasting and also tiresome.” Jackline K.

“The reason as to why I am interested in this water project is to know why some of the areas in Kwale County and all other parts in our country have scarce water supply? And what causes this? And what are the things which we can do to avoid this?” Halimah A.

The clubs are now working on group projects with remote support (via WhatsApp groups!) from staff and students at the University of Oxford. Meanwhile, Gro for GooD researchers and the clubs’ champion teachers are preparing material for a resource package that will capture the learning from the programme. We are also working on developing partnerships and networks for wider dissemination of the resources in Kenya.

It is inspiring how much these students want to deepen and share their understanding of water. Whether they decide to pursue careers in water management or simply become better-informed members of groundwater-reliant communities, the knowledge they gain through the water clubs will help them have a positive impact.

“When the club was introduced to my school I saw it as a big opportunity and decided to join it because I knew I would get ideas that would help back at home. My hope is that I will learn several ways to purify water which will bring an impact back to my home county.” Fatma M.
