As a Laidlaw scholar, Jensen Njagi ’25 spent the summer doing community-based translational research in his home country of Kenya. As a Global Development major, Jensen is driven by a purpose to improve community health while considering the social, economic, and environmental factors that shape it. His most recent research focused on issues at the intersection of waste management and food insecurity, with an overarching goal to mitigate climate change and reduce morbidity and mortality associated with poor sanitation. As a junior researcher on the team at Poverty and Health Integrated Solutions, Jensen utilized methodological skills including research study design, study implementation, and data analysis related to Circular Bionutrient Economy (CBE) pathways. In this blog, Jensen shares how he leveraged GIS tools such as R-GIS, to identify opportunities for utilizing Organic Underutilized Resources (OURS) in Kenya. 

At the right place, at the right time, with the right people.

Working with Charles Midega, Director of Poverty and Health Integrated Solutions (PHIS) — a national research and development organization that aims to improve health by addressing proximal causes of poor health — and Rebecca Nelson, Professor in the Department of Global Development and School of Integrative Plant Science, has been truly inspiring. The two are among the pioneer researchers on Circular Bionutrient Economy (CBE), a subset of Circular Economy (CE) that facilitates the transformation of organic waste into valuable products. They have been my mentors and supervisors, and together, we’ve been working at the nexus of public health and agriculture. We are also part of the Circular Bionutrient Economy Network (CBEN), a network based on CBE principles that unites an interdisciplinary international community from East Africa and beyond.

To collaborate.

At the beginning of time as a Laidlaw scholar, I was excited and anxious about how I could channel my energy, skills, ideas, and training in international development, to best contribute to the CBE projects and opportunities that lay ahead. One of my first engagements involved collaborating with the Farmers Research Network (FRN) in Western Kenya, which Prof. Midega helped spearhead. SOFDI (Sustainable Organic Farming and Development Institute), an NGO based in the region that works to improve livelihoods through sustainable agriculture and rural development, joined the alliance. Together, we started laying the groundwork for efforts to catalyze the adoption of resource-recovery agricultural practices that could utilize various waste streams available in the region to address soil nutrient depletion.

Shared prosperity in a people-centered economy.

At the heart of CBEN is the FRN — an innovative network of farmers working together to transform their farming practices. It’s a network where members learn from one another, leaving no one behind towards shared prosperity. Not only are they pioneers, but they are also incremental strategists leveraging CBE to address many challenges at once- improved yields and soil health as well as economic sustainability. I was truly impressed by the farmers’ innovative ideas for leveraging CBE principles to promote agroecology and seize business opportunities that exist within agricultural value chains.

Pioneering farmers within the network inspired those around them, who in turn inspired others. To me, this was a profound example of one of the ways that lasting change happens; the accumulation of power and agency at the grassroots and individual levels. Nevertheless, I also acknowledge that institutions, the private sector, and policy reforms play a key role in catalyzing change. Our efforts drew a lot of inspiration from the community-led development and capability approach that aims at enabling people to become agents of change in their own lives and communities. We’re not the only experts; a lot of our engagements involved a lot of learning — learning at heart with an action-based mindset that empowered everyone in the process.

Driven by innovation and action-based research - BSF Research.

Our engagements and action-based research at PHIS were not just about valorizing organic waste. I was involved with almost anything that revolved around agricultural and environmental sustainability, sustainable development, as well as public health.

Seizing opportunities while expanding the good.

One of the CBE projects we worked on involved the bioconversion of municipal organic waste such as fruit and vegetable waste from the market and fruit vendors, into a biofertilizer and animal feed by leveraging the Black Soldier Fly (BSF) technology.

Fruit and vegetable waste in sub-Saharan Africa presents consequential levels of wastage at both the upstream and downstream stages of the supply chain due to poor handling during harvesting and distribution, as well as poor storage conditions exacerbated by their perishable nature. Valorizing such unavoidable waste including other organic byproducts of the food system such as potato and pineapple peels could have a considerable positive impact on the sustainability of the food system.

“You have to add something to the magic vase for the magic to happen” - John Ruskin.

The BSF Larvae (BSFL) flourish on most organic waste substrates. They consume different organic waste such as municipal organic waste growing into protein-rich biomass and eventually leaving behind a nutrient-rich residue known as frass. The harvested larvae can be used to formulate animal feeds and the frass can be used as a valuable soil amendment. The transformation of organic waste via BSF helps to address two major global challenges of food insecurity and waste management, and with more attention, it could help close the loop within CBE. Besides researching the quality of the nutritional composition of BSFL reared on different organic municipal waste streams that are readily available in Kisumu City, we also explored how the BSF technology could be harnessed to create viable small businesses. This could be a promising business opportunity for nutrient recovery from organic waste and help reduce municipal public budget allocations to waste management.

Working with communities in Western Kenya reinforced my passion for improving community health and addressing the Social Determinants of Health (SDH) in a quest to improve livelihoods and foster sustainable change within communities in Kenya. This experience has inspired me to apply for a Master of Science in Public Health in Community Health with a focus on strategies for working with individuals and communities to achieve better health outcomes. Nevertheless, working with Prof. Charles Midega at PHIS inspired me to join him in his efforts to address SDH by catalyzing community-led and people-centered initiatives that improve the livelihoods of vulnerable communities in Kenya. Guided by the PHIS motto “Health and Wealth for All,” and its mission to achieve better health outcomes and improve the social and economic well-being of vulnerable groups, I am thrilled by the opportunity to effectively address health-related challenges faced by these groups in Kenya. I also look forward to how we can leverage innovations and technology and partner with other stakeholders to scale up these efforts across Kenya.
