Meet Tanzanian Scholars Transforming Water Science and Inspiring Girls

On this week of the International Day of the Girl Child, we laud not just the dreams of girls worldwide but the women who are making those dreams a reality. Today, we highlight an inspiring Regional Scholarship Innovation Fund (Rsif) scholar Dr Tusekeli Alfredy whose groundbreaking research is paving the way for future generations of girls. Their work is not just reshaping science but empowering young girls to imagine new possibilities for their futures. We sat down with Dr Tusekile Alfredy for this interview.

Q: Can you tell us a bit about your research journey? What inspired you to pursue a career in Material Science and Engineering?

A: My research journey is deeply rooted in personal experiences and the challenges I faced when growing up. I am Dr Tusekile Alfredy, and I pursued both my MSc and PhD in Materials Science and Engineering at the Nelson Mandela African Institution of Science and Technology. My research focuses on water treatment, specifically using cost-effective materials sourced locally and transforming waste into valuable resources.

I was inspired to explore water treatment due to the struggles I experienced growing up in a village where access to clean and safe drinking water was a constant challenge. In my village, we had only two water options: the river and the spring. Although people believed that spring water was clean and safe due to its clear appearance, in reality, we had no proper treatment methods. River water, which was used for domestic purposes, required long journeys to fetch. My sisters and I would walk hours each day to bring water home, a burden that typically fell on women and girls in many African cultures.

Three key words—health, gender, and education—always come to mind when I think about water. These experiences ignited my passion for water research. Growing up in an area affected by high fluoride levels in the water further fuelled my dedication. Fluoride contamination in Arusha, especially in the Meru district, causes significant health issues such as dental fluorosis, a condition that affects my daughter. Watching her teeth change color daily was alarming, and I realized the connection to fluoridated water. I switched to bottled water for her, which ultimately inspired my PhD research on fluoride removal. Facing these real-life challenges motivated me to focus on developing effective water treatment methods, hoping to alleviate water scarcity and protect people from water-related health issues.

Q: Were there any challenges you faced along the way, in STEM? How did you overcome them?

A: Yes, challenges in research are inevitable, especially when balancing the roles of a mother, wife, and researcher. It can be quite demanding, but all of these roles are incredibly important to me. To overcome these challenges, I firmly committed to myself that nothing would stand in the way of achieving my dreams. With careful planning, I worked to balance my responsibilities, and through perseverance and faith, I managed them successfully.

Q: Can you briefly explain your current research and what inspired you to choose this field?

A: Currently, I am a project investigator of the project titled “Flow Capacitive Deionization for Green Removal and Recovery of Ammonium from Wastewater” which aims to contribute in addressing the challenge of costly and energy-intensive removal and recovery of ammonium/ammonia from wastewater using a chemical-free and low-energy technology known as flow capacitive deionization (FCDI).

What inspired me to pursue this research is the dual benefit it offers. The process removes ammonia from wastewater and recovers it, providing both environmental and economic advantages. This approach allows for the simultaneous treatment of wastewater and the collection of concentrated ammonia, creating a circular economy solution that is both sustainable and efficient.

Q: How do you see your research contributing to solving real-world problems, particularly in Africa or other developing regions?

A: In developing countries like Tanzania, where agriculture is the backbone of the economy, fertilizers are essential for achieving high crop yields. My research on the recovery of ammonia using an energy-efficient Flow Capacitive Deionization (FCDI) system at a larger scale offers a promising solution for locally producing fertilizers. This initiative has the potential to greatly improve agricultural productivity, reduce reliance on imported fertilizers, and enhance food security. By aligning with the agricultural priorities of Tanzania and other Sub-Saharan African nations, this project directly supports economic development goals and contributes to the region’s efforts toward sustainable growth.

Linking Research to the Empowerment of Girls

Q: In what ways do you think your research could impact or empower girls and women, either directly or indirectly?

A: My research has the potential to empower girls and women both directly and indirectly in several meaningful ways.

Water Access and Health: In many developing regions, women and girls are often responsible for fetching water. By developing efficient and sustainable water treatment solutions like Flow Capacitive Deionization (FCDI), we can improve water quality and reduce the time and effort needed to access safe drinking water. This would alleviate the daily burden of water collection, freeing up time for education, personal development, and economic activities.

Agricultural Empowerment: By promoting the local production of fertilizers from recovered ammonia, the project can enhance agricultural productivity. Since many women in rural areas are engaged in farming, access to affordable, locally-produced fertilizers could help improve their crop yields and income. Empowering women in agriculture can contribute to their financial independence and enhance food security for their families and communities.

Role Models in STEM: As a woman leading a research project in STEM, my work could inspire and encourage other women and girls to pursue careers in science and engineering. By demonstrating the impact of women’s contributions to solving real-world challenges, I hope to motivate more women to enter and excel in fields where they are often underrepresented.
