It is early in the morning when Lindsey Schwidder, Celestina Danso Arhin and Patrick Tannor sit down at the breakfast bar of a hotel in The Hague. The latter two, director and business developer respectively of Holland Greentech Ghana, came all the way from Africa. They are part of a Ghana Netherlands Business Council delegation and they are in the Netherlands to meet with Lindsey, Project Manager Water at Delft University of Technology. The two organisations are partners in the consortium behind SOSIA+.

Patrick, Celestina and Lindsey

Shared expertise

Lindsey is SOSIA+’s project leader. With a Masters in society, science and technology, she looks at the applicability of new technologies through a sociological lens. “In my work”, she explains, “I always try to figure out how complex technologies could work in practice”. Lindsey coordinates various international collaboration projects at TU Delft, of which SOSIA+ is one. “I am the nexus for these projects, responsible for ensuring that everyone can bring in their relevant expertise”.

Supporting farmers

“Using water efficiently and seeing farming as a serious business is still uncommon in Ghanaian horticulture”, says Patrick. “Smallholders use their farms to sustain their families and don’t always see it as a way to make money. We make useful technology and knowledge accessible to them, such as the SOSIA+’s smart irrigation system”. Lindsey adds: “This system will support farmers by providing irrigation advice regarding the necessary water volumes and duration of irrigation for the cultivated crop types. The use of real-time local weather data is unique in this regard.”

Accessible service

The project builds on years of collaboration between TU Delft, Holland Greentech and Ghanaian farmers. “A few years ago, together with TU Delft, we designed the ‘Farming as a Business’ course”, says Celestina. “While teaching the course, the idea arose to make an accessible smart irrigation service available to these farmers”. The innovative tool was designed in collaboration with Future Water, a Dutch consultancy and research company and TAHMO a social enterprise initiative, with hundreds of weather stations across Africa.

Local collaboration

“Farmers are not just users but also local partners in promoting and disseminating our service”, Patrick says. “Thanks to previous successful, long-term collaborations, there is strong support among the farmers for implementing a pilot project like this. The farmers we work with have realised first-hand that they can save a lot of money with our technologies, knowledge and services. This often makes them very enthusiastic about participating. They are truly our ambassadors and share their acquired knowledge and experiences with as many as 100 to 200 other farmers in the region.”

Experiencing impact

“We consider water conservation very important”, says Lindsey. “But Ghanaian farmers often have other priorities. That’s why we also focus on what matters to them. For example, we link our technology’s impact in the field to the reduced operational hours of the pump – in other words, to lower fuel costs.” Celestina adds: “The most important thing is that we really work with the farmers in the field and receive feedback from them. They are ultimately the ones who have to work with the system and feel its impact.”

Tool development

Lindsey explains that the pilot project aims to cover two growing seasons. “This will not only involve showcasing the service and monitoring water and cost savings, it will also make the SOSIA+ tool more accurate and smarter through corroboration by the farmers. In the coming period, we will train 15 farmers to irrigate a portion of their land using the smart irrigation system and to monitor the outcomes. And then, the pilot project will get started!”

Innovation in progress series

The Partners for Water programme follows several projects that received the Partners for Water funding from start to finish. Over the next few years, these projects will take you on their journey of testing the feasibility or application of innovative solutions to enhance water security abroad. You’ll be able to gain insights into their processes, collaborations with local partners and their potential solutions; as well as their struggles, challenges and their lessons learned.

Competition for fresh water

‘Drought exacerbates existing challenges in the Southern African region, such as food security and sustainability’, explains Ralf. ‘Population growth, economic development and the deterioration of water quality and availability brought on by climate change all contribute to increased competition for fresh water. But that’s not all. Take cyclone Freddy, for example; in a short amount of time, extreme heavy rains caused devastating flooding. For both the day-to-day and seasonal management of water resources, these issues require up-to-date information on forecasted water availability.’

The GLOW-project was initiated to address this need. Ralf not only acts as project manager; he was also involved in creating the operational system that GLOW uses. ‘The goal of this project is to pilot an operational service that forecasts – availability and demand – water resource information. Focusing on water stored in reservoirs, soils and groundwater bodies, the project spans across an entire cross-border water resources system’,  Ralph adds.

Dutch and Southern African expertise brought together

For this project, HydroLogic is working together with FutureWater and Emanti. Ralf explains: ‘HydroLogic specialises in providing decision support services for water managers through HydroNET; an open platform which translates massive amounts of data into useable information for water managers. FutureWater’s area of expertise is evaluation and planning: how do you optimally divide the available water? And Emanti is our local partner who understands all the main social, political, legal and cultural characteristics of users and catchments in Southern Africa.’

Transboundary water security

‘What makes this project unique is using and combining proven techniques to produce operational water availability and demand, up to several months in advance’, Ralf tells us. ‘This will help water managers to make timely decisions. GLOW will also provide this information on a transboundary catchment level. That means water managers from different countries work together to share information and make decisions that are primarily in the interest of the entire catchment – and not just for their own area’, Ralf explains.

‘Different existing models and systems interact with each other. One of the problems we had in this region was a lack of data; it’s hard to build and validate a complex system without it. That’s why we chose to work with techniques that have already been successful elsewhere. We also continuously talk to other HydroNET-users about their experiences such as what were their challenges and how did they resolve them? This way you can come up with a package of well working water management solutions.’

Co-creation with end users

Another way to gather knowledge is by speaking to all of the African parties involved: ‘Like the Joint River Basin Authority in Eswatini, an important stakeholder in this project’, Ralf says. ‘I’ve spent a lot of time talking to the end users – the water managers in the three participating countries. They are the ones making decisions on how to divide the scarce water. I often heard: “I’m missing information on this or on that, can you do something about this?” For me personally, it became my drive to support them in making water management in Southern Africa more sustainable. Understanding their needs and challenges is the starting point in achieving this.’

Pains and gains

Organising workshops is a good way to gain that understanding. Ralf adds: ‘We recently held one in Eswatini to gather regional knowledge. By using the concept of “pains and gains”, we identified the most important stakeholders, placed ourselves in their role and came up with direct solutions that benefit their interests. The fact that the local partners we invited also included their water stakeholder they work with, such as agricultural co-operations and disaster management organisations in the workshop was something I really appreciated. This not only demonstrated their involvement, but it also helped us a great deal to make sure that what we build fits well to the challenges they’re facing.’

‘We are the local partner for this project’, José explains. ‘Something you need in Mexico, because navigating the institutional, social, political and legal framework can be difficult. To give an example, there are three levels of government involved in this project. The Mexican water authority at the federal level, the state government which in this case operates the water utility and the municipality of Oaxaca. And because Oaxaca is a UNESCO World Heritage city we also work with the office involved in protecting archeological and historical sites.’

Bringing stakeholders together

The municipality is the driving force behind the project – promoting, operating and implementing it. ‘Their support and leadership are important to gain the trust of other stakeholders’, José tells us. ‘We are constantly in the process of working out how to best navigate this complex framework and bringing stakeholders together. We, for example, organise workshops and get more in-depth through one-on-one conversations. In addition, since this project is international, we also smooth over time zone and language differences.’

Important social places

Rainwater that would normally go straight into the sewage system is captured, filtrated and reused with the BlueBloqs technology. The project site was carefully chosen; a piped river runs underneath the street and furthermore there is natural aquifer. José adds: ‘Although there are more projects like this in Mexico, what makes this one unique is that we directly link the captured water to the end user, in this case a local market. Not only do they need lots of water, but markets are also important social places in Oaxaca. This way we hope to make our efforts visible to the larger public.’

Institutional frameworks

‘The technology works, and we can adapt it to the local context and conditions, but that’s not the biggest challenge. The difficulty for a project like this lies in navigating our legal and institutional frameworks. We are not quite as ready yet as, for example, you in the Netherlands. We are in close contact with regulators to ensure we get the right authorisation from them. We also formalise and explain everything we do. This way we earn the trust of all parties involved.’

Natural track to follow

Stakeholders are very interested in the scalability of the programme due to the water shortages in Mexico. ‘The opportunities and needs to do so are there’, José tells us. ‘This project is a first insight into how feasible it is. If we do scale up, of course there will be new challenges like finding other suitable locations to capture and filtrate water and finding the right end users. But, I believe that once this method has successfully been demonstrated, scaling up will be the natural track to follow.’

‘The Dutch government and PfW have been very supportive of this initiative. And they’ve been a role model to us as well, demonstrating how to work together with international stakeholders. So, I hope the Dutch government support continues so that we can keep finding innovative ways of establishing efficient methods for collaboration. This way we can make sure that the local adaptations of this great idea stay as close as possible to the original plan.’

Project leader

Calzada del Agua’s project leader is a passionate architect and urban planner, with a strategic vision and a love for water. After graduating from the University of Buenos Aires, Argentina, Nahuel moved to the Netherlands to study at Delft University of Technology. He worked on numerous international projects, with ‘water’ being a constant theme. “We try to integrate water into all of our spatial developments. Water is the engine of our processes and the centre of our designs. We have found that water has a different character in every country. One of the biggest mistakes is to think that your vision of water can solve it all. It’s important to understand how water is integrated in the local culture and how you can adjust your strategy accordingly”, says Nahuel.

Transforming challenges into innovations

Nahuel explains that Mexico struggles with both too much and too little water. The streets, especially in cities, often flood due to heavy rainfall. When he and his team were working on a masterplan for the municipality of Oaxaca, they were inspired to make use of the abundant rainfall. That is how this Partners for Water (PFW) subsidy project originated. Nahuel says: “To tackle both drought and waterlogging, we offer a circular water system that employs BlueBloqs technology. This technology facilitates local collection, purification, underground storage and the reuse of rainwater. To identify the best implementation site, we’ve developed a toolkit for conducting the necessary analyses. This approach is unique because we offer the spatial design and technical solution as a single product, resulting in an integrated water and space solution.”

Consortium Partners

In addition to awarding the subsidy, Partmers for Water has played another role during the project’s preparation. Nahuel explains: “After we were inspired to start this project, we contacted Partners for Water with our idea. As it turned out, they knew of an innovative startup that was already developing a circular water system. This led to a great collaboration with FieldFactors and our application for the subsidy.” From previous projects, Nahuel was already familiar with their local consortium partner, Centro SC. This consultancy agency excels at establishing the right local connections and analysing Mexican regulations, which is essential to navigate through the country’s various and complex bureaucratic systems and conducting the feasibility study.

Collaborating with local partners

BD+P has been implementing projects in Mexico for over 13 years, including previous successful collaborations with the municipality of Oaxaca. This has provided a solid foundation of trust for the current collaboration. Nahuel says: “With this project, the municipality of Oaxaca is making a statement about how water can be used in a different way. This statement aligns with the municipality’s vision: a city that promotes education. The stakeholders are included through design workshops, brainstorming sessions and interviews. The municipality intends to use the collected and purified rainwater for various water users, such as bus stations, hotels and markets. This recycling of water helps to solve their water shortage problem and reduces the financial costs of water usage.”

In the field

With a smile on his face, Nahuel talks about the existing challenges: “There are various laws and regulations in Mexico that sometimes overlap. In addition, data is often lacking. While you can easily request data in the Netherlands, here you often have to measure it yourself. Usually, we see a project as a linear process, but that is not the case here. We are going from A to B to Z and back again. As a result, we can say that the project is progressing a little less smoothly than planned.”

Next step

“At the moment, we are in the midst of our feasibility study. The outcome of this study will determine whether the project is technically and financially feasible. If it proves to be, we will apply for the next PFW-subsidy round to start a pilot project!”
