Charting the evolution of rural water services delivery across continents

This year we are celebrating 30 years since the Rural Water Supply Network was formally founded. From very technical beginnings as a group of (mostly male) experts – the Handpump Technology Network- we have evolved to be a diverse and vibrant network of over 13,000 people and 100 organisations working on a wide range of topics. Along the way, we have earned a reputation for impartiality, and become a global convener in the rural water sector.

RWSN would not be what it is today without the contributions and tireless efforts of many our members, organisations and people. As part of RWSN’s 30th anniversary celebration, we are running a blog series on rwsn.blog, inviting our friends and experts in the sector to share their thoughts and experiences in the rural water sector.

This is a guest blog by RWSN Member Lilian Pena P. Weiss based in Washington DC, USA.

I started working in the rural water sector in 2002, in my very first assignment with the World Bank, when I was part of a team assessing the social and environmental impacts of rural water systems in the dry northeast part of Brazil.  As a recent engineering graduate, I was very much focused on the infrastructure – but I quickly learned that sustainable rural water services need to take into account a lot more than that. I remember vividly exchanging with the rural users on how to organise the community associations for managing water services, discussions on tariffs, Operation & Maintenance, and support from local governments amongst others.  Since there, I never stopped working on delivering rural water services

In the early 2000s in Latin America, I worked on many projects in rural water services to indigenous and Afro-Latin communities that had been financed by the Inter-American Development Bank and the World Bank. Through those, I gained a better understanding of how these communities value water, the related cultural connections, and their willingness to have and pay for better services! This underlined the importance of working on the social side, especially behavior change and communications to make rural water services sustainable. At the time, the Demand-Responsive Approach (DRA) was the mantra with rural water practitioners! Some of the lessons learned from my engagement with Indigenous communities in Latin America and the Caribbean were later captured in this publication.

Around 2010, we started to develop a joint rural water information system, SIASAR, with Honduras, Nicaragua and Panama, which has since turned into a rural water platform across 14 national or subnational governments, from Costa Rica and Uganda to Kyrgyzstan.  Developing SIASAR has been one of the most interesting and rewarding initiatives of my professional career so far; we worked hand in hand with multiple countries to develop – from scratch – a new governance and structured information system that focused on service delivery and sustainability with active participation from local users up to central governments harmonized across a wide range of countries.

It was around 2012 that I became involved in the Rural Water Supply Network. At the time, I was co-chairing the internal rural water thematic group of the World Bank together with my colleague Miguel Vargas. The interactions with the RWSN I believe were a win-win for us and for them. The RWSN with its powerful outreach and strong presence in Africa could deepen our dialogue and understanding of how to reach the last mile in rural water supply and give us the opportunity to exchange lessons and initiatives with so many institutions working on the same topic. At the same time, the World Bank’s global perspective also helped the RWSN to expand beyond Africa.

Later in 2015, I was fortunate to join the World Bank’s team in Vietnam, to lead a new generation of rural water projects where financing was fully based on results. It was fascinating to evolve our dialogue from delivering tanks and connections to really focusing on ‘how can we make sure these systems will deliver 24/7, reliably, with O&M cost recovery and sustain over the years? The work started in Vietnam has scaled up globally; this blog gives a good overview of the lessons learned from this approach in Vietnam. To date that the World Bank has supported more than 20 programs for results in the water sector globally.

Although so much progress has been achieved in rural water over the last 20 years, from an old top-down, infrastructure-based approach, to the evolution of the CBO-based models with institutionalized backstopping support, and growing Private Sector Participation,  the challenges ahead remain complex. Not only do we need to continue working to ‘leave no one behind’,we also need to promote better and more efficient levels of service (ie. household connections, 24/7 supply, financial sustainability, etc). Moreover, climate change and its impacts on water security are perhaps the greatest challenge for this decade. Rural systems and their water sources are naturally more vulnerable to extreme climate events. The role of Development Partners, including the RWSN, become increasingly important to work with Governments, rural water practitioners, academia, and the private sector to develop and deploy effective solutions and advocate for the necessary funding to ensure universal, sustainable and climate resilience rural water services.

3 ways to improve water security for climate resilience

1. More accurate and granular analysis of climate risk is needed to increase relevance of climate information
2. Metrics for monitoring climate resilience in water systems are critical to track progress and inform investments for water security
3. New institutional models that improve water security will be critical for climate resilience

Dr. Katrina Charles, REACH Co-Director

In case you missed it, last week REACH launched its new Water Security for Climate Resilience Report, synthesising six years of interdisciplinary research on climate resilience and water security in Africa and Asia. You can also read a summary of the full report with recommendations.

The REACH programme has been partnering with RWSN since 2015.

Water security and climate resilience are interlinked.

This may seem like a simple statement, but in reality it is a complex relationship. Water security and climate resilience are both about managing risks – from water-related issues and climate-related hazards, respectively – to achieve better outcomes for all sectors of society. There are intuitive relationships at large scales, but underlying them are complexities shaped by the environment, and our interactions with it.

Climate change headlines often focus on temperature increases. These changes will be significant and have severe impacts as highlighted by the heatwaves in recent weeks in North America, Pakistan and India. These increases in temperature come with dramatic changes to our weather, in turn affecting the complex water systems that are essential to so much of our lives and our planet. Floods and droughts are the most visceral example of this impact, which also receive regular coverage on the news. But climate change is affecting water security for humans and ecosystems in many more subtle ways.

Climate change is impacting our drinking water supplies. There is a limit to how much capacity they have to absorb weather extremes, especially for smaller systems. Heavy rainfall is linked to many major waterborne outbreaks in developed countries. A major drought led to severe water rationing in Cape Town in 2018, nearly causing the city’s taps to run dry, known as Day Zero. The report highlights that for smaller water systems that people outside cities rely on the impact of weather is often less clear, but the evidence is that there is limited climate resilience.

Water quality varies with weather. Rainfall increases the mobility of faecal contamination, with different types of system more vulnerable to heavy rainfall, exposing the users to diseases such as typhoid. Without reliable water supplies, people use a range of water sources to meet their water needs year-round, trading off risks between reliable water supplies that might be saline or expensive, with seasonal but unsafe water sources. Climate change will increase weather extremes leading to increased contamination and less reliability.

Fresh water scarcity is increasing. Industrialisation and urbanisation are increasing both the demand for fresh water and its pollution, with toxic compounds that are difficult to remove. Climate change is amplifying these threats by reducing the availability of reliable water, increasing salinity, especially in coastal areas, and changing river flows that flush saline and polluted water. Reduced river flows from changing rainfall patterns will increase exposure to pollution for those who rely on river water for washing and bathing, and increase saline intrusion from the coast. Building resilience requires better management of fresh water resources to reduce the increasing contamination that is making water harder to treat.

To build the adaptive capacity of water systems to cope with changes in climate, climate information needs to be available to water managers at the appropriate spatial and temporal scale. Ensembles of global climate models provide useful information about global climate, but analysis is needed to identify the relevant climate models that best capture local climate. More investment is needed to provide the tools that water managers need to make informed decisions to increase climate resilience, such as accurate projections at local scales and seasonal forecasting based on understanding of local climate drivers. The information needed varies for different users, but is critical to build resilience for managers of small water systems, reservoirs, and basins.

The report synthesises six years of interdisciplinary research by the REACH team across Sub-Saharan Africa and South Asia. Collaborations in our Water Security Observatories have allowed us to understand how water security risks are experienced, how inequalities are created and reproduced with new policies, and how new tools and science can support better decision making. The report highlights the impact the REACH programme has achieved with funding from the Foreign, Commonwealth & Development Office (FCDO), in partnership with UNICEF, for the benefit of millions of people. It concludes with three recommendations for to advance water security for climate resilience:

  1. More accurate and granular analysis of climate risk is needed to increase relevance of climate information
  2. Metrics for monitoring climate resilience in water systems are critical to track progress and inform investments for water security
  3. New institutional models that improve water security will be critical for climate resilience

Climate change will increasingly affect water availability and quality, with devastating consequences for the most vulnerable. Improving water security is critical to build resilience to the changing climate.

What you always wanted to know about central and southern Africa’s climate – A beginner’s briefing in 15 minutes or less followed by discussion

Please join us for this Future Climate for Africa webinar by climate change expert Neil Hart.
Friday 17 March 2017, 11:00-12:00 (London, GMT); 13:00-14:00 (Johannesburg)

Register for the webinar here.

Climate modelling is a key tool in tackling the effects of climate change. Future Climate for Africa is a research programme that aims to generate fundamentally new climate science, and to ensure that this new science has an impact on human development across Africa. The UMFULA research team is using climate models to try and improve information about the future climate of central and southern Africa. Their aim is to provide decision-makers with the best possible scientific knowledge on how rainfall, temperatures and associated conditions like drought are likely to change in the region in the next 5-40 years. The researchers also seek to help decision-makers understand which aspects of the future climate are simply uncertain – and to explore the implications for investments in development planning and infrastructure that could endure for decades ahead.

This webinar by Neil Hart of the University of Oxford will explore in brief some of the research questions that the FCFA teams are pursuing in central and Southern Africa. This webinar is not for climate specialists but for anyone who is interested in how they could be using climate change information to make more climate-resilient development decisions.

Dr Hart will explain in brief and in layperson’s terms how climate models project as clear a view of the future climate as possible, but are often misunderstood or used incorrectly. He will debunk some common misunderstandings about climate models. The seminar will use illustrations from what we already understand about central and southern Africa and discuss the implications for making climate-informed decisions.

Dr Hart will cover the basics in 15 minute or less then open the discussion for participant questions and answers.

Social Dimension of Water Resource Management in Sri Lanka – Part 5

by Delgollage Senevirathne, Assistant General Manager (Sociologist) at the National Water Supply & Drainage Board (NWSDB), Sri Lanka.

(8) The social consequences of failure to control excessive ground water extraction

There are many instances where excessive groundwater extraction affects the availability of groundwater for other users leading to social consequences. Over extraction of ground water from a plot of land has a negative impact on the use of groundwater from the adjacent land users in case of simultaneous extractions are affected. If one party continuously extracts groundwater it will impact the aquifer and will become unsustainable in recharge levels.

In Sri Lanka, there is no legal provision to control use/ extraction of groundwater in terms of quantity and quality parameters.  Hence there is a need to introduce controlling legislation to manage the groundwater resources which is impacting on social consequences.
