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+.

Lindsey, in fact, 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".

"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."

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.

"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."

"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."

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!"
