Blog 2: Technology and Business in Tanzania

About forty minutes from the center of Dar es Salaam by car, near the Julius Nyerere International Airport, is a small fenced-in set of buildings in a town called Kitunda. These buildings house the Science and Technology Innovation Center and Laboratories, or STICLab. I had an opportunity to visit STICLab with my fellow interns and found both an inspiring story of entrepreneurship and a demonstration of the ever-increasing presence of technology and engineering in Tanzania.

Just getting to STICLab is an experience for someone from outside Tanzania. The main road to get from DIT to STICLab is the same road that Aarohi and I experienced coming from the airport into Mchafukoge, where our hotel is located. As a result, this road served as a kind of first impression of Tanzania. The main thing that surprised me was the number of people on the side of the street. It was striking to see so many people just walking around – some buying or selling various things and others seemingly with no definite purpose, often greeting other pedestrians as friends. Closer to the center of the city, many people were walking along the lines of traffic selling various foods and objects – in our first taxi ride, Aarohi and I were surprised to see a salesman approaching car windows to demonstrate two of the large knives he was selling. On the way to STICLab, we passed the same man before turning onto a side road.

This road, although somewhat less busy than other ones throughout Dar es Salaam, is representative of the road conditions we have experienced here .

The side road was like many smaller streets that we have seen throughout Dar es Salaam. While the central roads are not unlike those in the United States, the side roads are often made from dirt or sand. These degrade at certain points, leaving pits and bumps that make car travel slow, difficult, and bumpy. Along the sides of these streets are houses and businesses, many with hand-painted signs or advertisements and owners or customers standing outside, which gives these streets a welcoming atmosphere. On some of the roads, chickens, goats, and even cows owned by nearby families roam free. But while each street seems unique, many are not marked clearly or extend in seemingly random directions, making navigation difficult.

From where we finally left the cars, we walked down a small drive and past a house with several children playing in the yard. Just beyond this, STICLab is run from a similar house that once belonged to one of the founders.

STICLab is surrounded by a chain link fence and concentrated around the main house, which contains offices, an electrical/mechanical prototyping space, and a machine room with 3D printers, a CNC machine, a tensile testing machine, and three microscopes undergoing fatigue testing as part of an open lab instrumentation project. In this room, all devices except one 3D printer were built at STICLab.

Around the main office, there are several large pavilion-style tents with hydroponic farming setups as part of an ongoing process to cultivate lettuce within Tanzania. A few other buildings and tents that we did not get to see are arranged around the rest of the lot. One area contains the water tower for the property, on which a water level monitoring and redistribution system is being tested for a local hospital.

Paul Nyakyi from STICLab (to the left of the solar panel) showed our group several ongoing projects around the property.

In the open space between, a few men are cutting and assembling a metal frame for an unknown purpose. STICLab manages several projects at a time, variously funded by local and international grants or contracted by local businesses.

STICLab was founded by a group of students and one professor from DIT. They achieved early success for their MajiPesa system, a solar-powered water vending and tracking system that takes coins to dispense water while relaying various information to the owner of the machine through a web interface. The system is sold to those responsible for supplying water and helps them to easily manage several machines at once while increasing the simplicity and transparency of water transactions.

This picture from the project website shows a MajiPesa system installed in an area of Dar es Salaam – “Maji” means water and “Pesa” money in Swahili.

In Tanzania, these water distribution points are often the only nearby source of water in a community. As a result, they have historically been a gathering place for community members. An article on NewGlobal accounts how one MajiPesa owner has set up retail spaces near the water system; the businesses that rent the space will have guaranteed foot traffic, improving their reach and profitability. Thus, MajiPesa has served as a method of bringing technology and entrepreneurship into a timeless cultural fixture. This is a great example of Tanzanian design focused on uniquely-African needs – because water delivery is not common in many areas of the world, no comparable system existed.

For contrast, we can look at PlayPump, an oft-cited example as a failure of global engineering design. The PlayPump was a high-profile effort aimed at solving the problem of water availability in village settings across Africa (focused in South Africa) by harnessing the energy of school children spinning a merry-go-round to pump groundwater from an aquifer into a water tower for later access. The successes and failures of the PlayPump have been analyzed extensively in media, from travel and global health blogs to PBS’s Frontline.

The PlayPump aims to use existing energy resources to increase water availability (Photo).

The PlayPump achieved success in some settings but is generally thought of as a failure because it was expensive, ineffective in some regions, and prone to failure without regular maintenance. In addition to some engineering, ethical, and basic feasibility concerns, the PlayPump failed to properly anticipate two important considerations in global low-resource design – maintenance plan and cultural interaction.

The success of a maintenance plan is largely dependent on the presence of capable technicians and the cost of repairs. Each PlayPump has an initial cost of about $14,000 to cover materials, installation, and water testing this cost is provided entirely by donors. In an attempt to offset some of this expense, the water tower contains two company advertisements. While it is difficult to know the exact economics of this, it is reasonable to say that the majority of funding still came from donors. In addition, maintenance has to be provided from donor funds. Because funding has to be secured for any repairs, PlayPumps have faced the issue of breaking and sitting unused for long periods. This reveals a major flaw with the PlayPump model – that the community has no stake in the technology. It is designed, funded, and installed by outside sources and relies on external maintenance. Even if someone in a certain community has the skills to fix a broken pump, they lack the funding and motivation. The lack of motivation comes from the other consideration, cultural interaction.

While choosing the energy source of children playing shows some consideration of cultural setting, the PlayPump displays an ignorance of the way that water is traditionally acquired in these communities: community members, often women, walking to the nearest water source and retrieving it. This became significant because the solution did not account for this existing tradition; in fact, the PlayPump eliminated this source of social interaction entirely when it was able to work successfully. This decreased motivation to repair the pumps significantly. The cost and hassle of repairing the PlayPump were so high and the community stake in the technology so low that the device was unlikely to be repaired.

Although MajiPesa is meant for a different environment and solves a slightly different problem, it is a tremendous example of the future of design that Rice 360 and other global design institutions are trying to support – solutions driven by local stakeholders that account for the needs and cultural settings of the area. The differences between MajiPesa and PlayPump on these factors are striking. While PlayPump was driven by outside donors, MajiPesa is created by a local company and owned by local entrepreneurs. This means that when the system encounters some issue, a local owner is financially motivated to fix it and can lean on resources that are available locally to get the technology repaired. More significantly, MajiPesa not only accounts for but embraces local cultural resources. It replaces the outdated parts of water supply without ignoring the role of water gathering in the community. In fact, adding transparency and consistency to the system has allowed for the incorporation of technology and business into the existing behavior. Because the technology is locally designed, it can also adapt to the rapid changes occurring in Tanzania. When the machine was first prototyped, it took only coins to dispense water. In recent years, however, m-pesa (a mobile money transfer system) has become popular in Tanzania; in consideration of this, current MajiPesa machines will soon take m-pesa payments to dispense water. Designs like the PlayPump that are subject to outside funding and generate no community stake do not adapt to a rapidly-changing modern Africa.

As I reflect more on STICLab, I am convinced that this kind of innovative maker space/business is critical to the successful advancement of technology in Tanzania and similar countries. From the interaction we have had with the people at STICLab, it is difficult to get a complete picture of how the business functions. It is clear, however, that it is built around a group of good engineers using available resources to provide feasible, lasting technologies suited to the unique needs of their environment. This allows STICLab to use cutting-edge technology while still maintaining a connection with the local environment. Over the rest of my time in Tanzania, I plan to consider how this spirit and business model can be adapted to satisfy medical needs, which often require even more complex funding sources and market considerations.

Blog 1: Communication

“It tastes like something, but I can’t put my finger on it..”
“What do you mean? What do you put your finger on?”
Today I tried ugali for the first time, and in the process remembered how important it is to foster good communication.

Ugali is a dense cornmeal substance served beside and used as a tool for eating green vegetables, meat, beans, and other substances. I now know that something is polenta.

Here in Tanzania, the national language is Swahili with English also being used in many governmental and educational settings. On becoming independent in 1957, the first president, known often as Mwalimu (“teacher”) Julius Nyerere, established Swahili as the national language, with students being taught in Swahili through primary school and then in English for secondary school. This was an effort to unite speakers of the over 100 regional or tribal languages present in Tanzania. Today, most natives speak both a tribal language and Swahili.

The adoption of an official language, among other factors, has led Tanzania to develop a strong national unity. However, this can make it harder for outsiders to communicate. In countries like Malawi, where no one language is ubiquitous, many people are familiar with English. In Tanzania, however, it is unusual for us to meet someone outside of the university or hotel with conversational English skills. Even at the university, most non-technical conversations default to Swahili. For those in the outside environment that do speak English, they likely do not speak enough to engage in more technical conversations; this becomes significant when identifying needs and interviewing technology stakeholders.

Throughout my life, I have had the luxury of never having difficulty communicating. In my daily life in the United States, it has been a continuous assumption that anyone I communicate with will be able to speak English; additionally, they will often understand the idiomatic language that is used. At Rice, I have been working on projects with those of a similar or complementary technical background – this has led me to communicate with certain assumptions about the knowledge and perceptions of the other person. With this mindset, it is easy to become frustrated if a team member does not understand a discussion.

The language environment here means that it can be difficult to communicate about medical or engineering concepts. While the engineering students are well beyond what I would consider fluent, many phrases or technical words do not translate well or are not used frequently enough to be recognized. Other things are just described differently here – some (like lift) are familiar, but others (like using soldering gun for what I would call a soldering iron and soldering iron for what I would call solder) result in miscommunications that require us to stop and clarify terms. Additionally, the design team comes from multiple disciplines within engineering and Aarohi and I are the only bioengineers. Thus, technical terms are often not shared and must be clarified.

Over the week of work that we have done so far, I have been forced to reevaluate the way in which I communicate. Sometimes I am not clear in my definitions, and other times I do not understand concepts with enough depth to describe them without using specific key words. Over my time here, I must work on my ability to clearly communicate technical concepts to a variety of different audiences. I will work to better identify whether everyone in the conversation is speaking in the same terms and understanding each other fully. Because of this, I believe that I will return to Rice a better engineer and communicator of technical concepts.

 

 

 

Blog 0: Excitement and Anticipation

Over the past week, my fellow interns and I have been preparing devices and researching supplies to take along for our respective projects. In three weeks, I am headed to Dar es Salaam Institute of Technology (DIT) in Tanzania. Over this time, we have been assigned four tasks: setting up a design kitchen similar to the OEDK at Rice, conducting interviews about three Rice 360˚ devices, identifying medical needs that might be addressed by engineers at Rice and DIT, and finding and completing an intern-identified project. All of these tasks come with unique challenges.

One of the three Rice 360˚ technologies we are taking is OxyMon, a continuous oxygen monitor intended to identify the state of oxygen concentrators and relay this information clearly to clinicians. I was on the team responsible for developing this device during the semester, so I have mostly been working to prepare this device to be taken abroad over the past week. At the advice of several mentors, we have been designing a version that is intended more as a diagnostic tool for technicians than as a continuous monitor; this includes making changes like displaying flow and temperature alongside concentration and adjusting the device so it is more comfortable as a handheld. I am extremely excited to gain feedback on this device from clinicians in a setting where it could be very useful.

The goal of setting up a design kitchen has also been a major focus for myself and the other Tanzania intern, Aarohi. One of the important goals of the global health program at Rice is to give local engineers the prototyping tools they need to take on design projects. One challenge that we anticipate in setting up a space like this is getting the word out that it is available. In order to encourage people to utilize it fully, Aarohi and I have discussed organizing a design challenge or hackathon to increase knowledge of the tools available. More specifics on the tools available in the design space will be provided in future blogs.

Another challenge that we have in Tanzania is identifying clinical environments for observation and interviews regarding the Rice medical technologies. Because we are only the second class of interns being sent to DIT, the connections are not as available as they are in Malawi. I look forward to this challenge as an opportunity to get out into the area and potentially explore different clinical environments.

While I find myself focusing on the challenges we will face, it is important to remember that where there is a challenge, there is also an opportunity. This summer will be full of opportunities not just for the achievement of our goals, but for my personal growth as an engineer. With that in mind, I look forward with excitement and anticipation.
