Problem Statement: How might we make urban farming more feasible? The design thinking process we used consists of four stages: Discover, Define Develop and Deliver. Under Discover, we explored some of the stakeholders that we had considered for primary schools, including students, teachers, as well as parents. For the Define stage, we analyzed the needs of our stakeholders and categorized them into different groups using Affinity analysis. From this we learnt that urban farming is currently expensive, time-consuming, space inefficient and is difficult to maintain. We hence wanted to make urban farming more hassle-free for these stakeholders so that their needs are addressed and urban farming can be made more feasible.

Our solution is named ReVert and consists of two main features: Vert, which is a vertical garden and Re, which is part of shaRe schools produce exchange. The vertical garden incorporates many attractive features such as the infrastructure, watering system, and ladder. Under the infrastructure, we have attachable rows which can be assembled to form the full structure and be connected between different units. This makes our solution more flexible as schools can purchase the required number of units depending on the space constraints.

For the watering system we initially had a central pipe to water all levels of the vertical garden. After collecting feedback from pilot testing interviews, we included an auto measure water system which works similar to the toilet cistern. For the SAP soil, we will be using fruit and vegetable peels sourced from the canteen vendors. They contain superabsorbent polymers that are a good source of pectin, to improve the water retention property of the soil.

Lastly, to allow the children to have a safe, accessible way to look at the plants, we have a ladder with treads. To enhance the educational aspect for our solutions, we will have an educational block on each floor of the vertical farm when the students climb the ladder to view the plants that they have grown. They can read these plaques with fun facts and additional information about each plant species in order to deepen their knowledge and understanding about Urban farming in Singapore. With more time and resources, we will expand our Xchange Produce programme onto an interactive urban farming bus. This is to accommodate schools that do not have the space required for a permanent urban farming set up. The bus will move to the different primary schools within the same neighborhood to showcase the different vertical farms and learning experiences of the students. Since the vertical farms are detachable from the wall, the whole vertical farm could be brought onto the bus. Multiple vertical farms from multiple primary schools could be brought onto the bus and the bus could move to different primary schools regardless of whether the primary school is able to implement our full solution or not.

This enhanced system would ensure that primary schools would be able to educate their students about urban farming regardless of whether they implement our full solution or not. We are looking to potentially expand or perhaps implement our solutions through different channels by partnering with organisations such as Temasek Primary School and Inspiring Girls.
