Malawi Project Greenhouse Charter 2023-24 – Tufts Engineers Without Borders

Tufts Engineers Without Borders is constructing a Malawian Mobile Greenhouse, which serves to teach sustainability, international culture, engineering skills, environmental awareness, and more to Tufts and

At the start of 2023, the Malawi Chapter of Tufts Engineers Without Borders had a happy issue of too many members, but not enough to do. Our project was very internationally focused with a remote implementation. With a project starting in 2017, our clean water-access project has a long history with lots of background knowledge that was hard to explain to new members in a digestible way. Because of this, there was not enough hands-on engineering in our weekly meetings. It was also hard to connect members with our Malawi project and culture.

Furthermore, we wanted to have an on campus space to connect with the greater Tufts community and show off our excitement for EWB. Aligning with the values of Engineers Without Borders, our chapter wanted to focus on a locally based, but internationally focused sustainable, environmentally friendly project.

With this project, we will be able to learn how to timeline an engineering project from start to finish, mobilize our tech groups to create something they can see, build, and take ownership for and also teach by doing the different aspects of an engineering project. Our chapter also could take methods of fabrication, design, and prototyping from the classroom into something we could work on and build in our weekly meetings. Skills such as CAD, strength simulations, laser cutting, 3D printing, community surveying, project management, and more could be applied throughout the journey of this project. All these skills learned through Project Greenhouse are the same skills needed for our Malawi Project; Showing and learning it through a smaller and local project, rather than just explaining it, was very beneficial in teaching what an Engineers Without Borders projects are all about.

Project Greenhouse FAQs

We are already partnered with the Eliot Pearson School and have taught inital lessons to the classes of 3-5 year old students. This partnership will continue throughout Spring 2024, and our greenhouse is going to be one of the three pillars of learning for their semester. We are working with the Sustainability Committee in the Tufts Senate to plan interactive student and community events. We plan to host at least one event per semester with the local community. We have committed a portion of our project to designing and forming community events to teach STEAM activities, engineering sustainability, and other interactive activities with local elementary schools and groups.

Maintenance and Long-Term Considerations:

Who will ensure the greenhouse is maintained and kept in good condition during summers? Will there be students around to maintain?

After communication with the Garden Club, they’ve noted a successful summer turnout in terms of garden maintenance. Considering that most upper class students live on campus during the summer, and that many professors remain on campus, we’re not worried about maintenance during the summer. We have a technical group committed to building a maintenance plan for the entire year, including special focus on the summer months. We’ve agreed to partnerships with the Garden Club about their willingness to help maintain our greenhouse in exchange for our help in their garden.

Have you prepared a disassembly plan? How might we ensure that it is not left in disarray after the graduation of current students?

The disassembly plan is not yet made. Of course, this is especially of interest to us and our Construction technical group has committed to creating this plan and estimating its cost as they are designing the construction plan. Our goal is to make this project long-term feasible and sustainable for the long term. We will not allow club membership to sink to a level at which we cannot sustain the greenhouse. In the unlikely circumstance that this does occur, we will ensure a disassembly plan is in place. This likely involves donation to a local school, community garden, or possibly a local house or farm which can be better able to maintain the system if the club can no longer spend resources to maintain.

Have you ensured that a location is available for the greenhouse? Does this greenhouse take up important spaces used for graduation ceremonies or otherwise?

We are in the process of coordinating a location with Tufts University that will ensure it can remain in state for the long-term. Many spots are under consideration at present, and given the popularity of pollinator gardens, community gardens, etc. on campus, we expect we can make an agreement with one of these groups to find a location. If this is not feasible, we have considered the possibility of a trailer-based greenhouse, though far more difficult from an engineering perspective, could be more achievable in terms of location and transportation.

Projected Project Timeline

SPRING SEMESTER 2023 Research – Inspiration after meeting with TAMU EWB and their Greenhouse – Initial research from each group → BIG BRAINSTORM – Met with Garden Club, Grounds, Dining, Sustainability – Communicated with EcoReps, Pollinators Design – Created initial drawings of interior and exterior, estimated dimensions and costs – Brainstormed plants and their containers – Learned how wire arduino and remote control	SUMMER 2023 Research – Traveled to Malawi – Drew new inspiration from the culture, nature – Talked with community members about foodstuffs, crop techniques	FALL SEMESTER 2023 Research – Redesign after further details on dimensions, location, etc… – Greater cultural focus on Malawi culture; teach the club, school, and local community about the Malawian community and their way of life Design/Prototype – Groups will finalize prototype designs for each Technical Group in the greenhouse (both in construction and in community planning) – Building planning will start with communication with Tufts/Medford/Somerville on construction permits, building code, and community events → will meet with REIC, local farms, garden clubs for expert opinionsTest and Showcase – December: big end of semester showcase to give a preview of what the project will be, and encourage groups to become experts on the skills they will need when building the greenhouse.
SPRING SEMESTER 2024 Design/Prototype/Test and Showcase – Confirm all designs and prototypes meet the needs of the community – Use feedback and proposals to improve / iterate designs as needed Build – Work with local experts and start building! (once there is no snow on the ground)	SUMMER 2024 Launch – Present it to the Public – Have a ribbon cutting ceremony and start official community outreach programs! – Initialize crops, plantings, water system	FALL SEMESTER 2024 – Club focus will shift back to international projects – Local focus will still be available to maintain and grow crops in the greenhouse – Conduct community events and open the greenhouse to the public school community – Present to incoming first-years as the hands-on creation of real Tufts Engineering students! An amazing option to present the school’s Engineering program, something you can walk inside, interact with and even taste and smell!
