Mak-CAES Hosts Hybrid Seminar on Finding the Best Cattle Genetics for Africa (OPTIBOV project)
OPTIBOV: Genetic Characterization of Cattle Populations for Optimal Performance in Africa Eco Systems
A large variety of local indigenous and commercial cattle breeds has been produced as a result of domestication and selection. This variety ensures the capability and adaptability of livestock to fulfil its role in food production under different circumstances, now and in the future. Local breeds exhibit unique adaptive features to harsh environments, which can be useful for adjusting mainstream breeds to climate change. Simply transferring high producing commercial animals to the African continent, will not be the solution due to low performance and even low survival under these harsh environments (ecosystems). The aim of the OPTIBOV project is to improve production and survival of traditional/indigenous breeds adapted to the local environments in Africa. This will secure the future of these well adapted traditional/indigenous local breeds.With combined effort from partners across the globe, the OPTIBOV project will help maintain traditional cattle breeds, capture adaptation, use known variations in production, train, educate & involve stakeholders to perform optimal breeding.
The project is coordinated in The Netherlands (Wageningen University and Research Centre). Participating institutions include; Makerere University, Uganda; Natural Resources Institute Finland; Agricultural Research Council Pretoria, South-Africa; University of Porto, Portugal; Cairo University, Egypt; and Taurus Foundation Netherlands.
Project members include; Dr. Richard Crooijmans, Wageningen University, The Netherlands; Dr. Donald Kugonza, Department of Agricultural Production, Makerere University; Prof. Juha Kantanen, Natural Resources Institute Finland; Dr. Nasser Ghanem, University of Cairo, Egypt; Dr. Linky Makgahlela, Pretoria, South Africa; and Dr. Catarina Ginja from Portugal.
The project is supported by LEAP-Agri, a joint Europe Africa Research and Innovation (R&I) initiative related to Food and Nutrition Security and Sustainable Agriculture (FNSSA).
An important deliverable of the project is a new genotyping assay specific for African cattle breeds which will include markers associated with specific traits.
Expected outcomes and impact:
- A uniform bovine phenotype scoring list for adaptation traits.
- Genome-wide information of the traditional breeds. Giving knowledge on the amount of diversity but also on the amount of inbreeding, detection of potential genetic defects and selective sweeps related to adaptation to a specific environment.
- The obtained information can be used to improve traits by selection of animals within or over breeds such as longevity, production and resistance to diseases. This will increase production, longevity and reduces cost for medical treatments which will result in breed performance in the next generations.
- Training of young researchers will be conducted to use the latest technology and techniques and how to implement the findings in breeding.
- Involvement of all stakeholders up to farmers by creating an APP, database and website to submit data and actively participate within the research.
Hybrid seminar
On 25th April 2022, the project team met at the College of Agricultural and Environmental Sciences (CAES), Makerere University to share updates on activities in the respective countries. The hybrid seminar was hosted by Dr Donald Kugonza and Dr Morris Agaba.

Issues arising from the research
1. Developments in SNP genotyping and next generation sequencing in South African indigenous cattle – Dr. A. A. Zwane
There is notable difference in using single nucleotide polymorphism (SNP) data and whole genome sequence (WGS) data in characterizing SA indigenous cattle breeds
WGS data holds the potential for the improvement of indigenous livestock breeds due to the in-depth analysis genome-wide
Genetic diversity studies give the understanding of population structure, demographic history, introgression and heterozygosity levels in South Africa indigenous cattle
Identification of selective signatures provides insight into selection events that have shaped the genomes of indigenous cattle breeds, and allows the identification of important genes
This will allow genomic selection, sooner, in the indigenous breeds, and more studies are needed for other indigenous livestock species
2. Application of genomics for livestock genetic improvement – Linky Makgahlela, ARC-Animal Production, South Africa
- Genomics drives biological efficiency of production, boosts livestock contribution for sustainable protein source
- Genomics promises cutting-edge solutions: Nutritional needs of all human beings, while safeguarding natural resources, and preventing environmental degradation
- Genomics enables farmers to increase efficiency, decrease production costs & prophylactics and limits expenditure of resources
- Research (and capacity development) ongoing for better understanding of breeds and to put science to practice
3. Genomic characterization of northern native cattle breeds – Prof. Juha Kantanen, Natural Resources Institute Finland
The gene expression analysis of the northern Eurasian breeds revealed;
- Several differentially expressed genes (DEG) that were associated with the eicosanoid metabolic process (ALOX15, ALOX5 and HPGD) in northern Finncattle and with immunity (CCL4, CCL5 CX3CR1, CXCR6 and PRF1) and the regulation of lipid transport (ABCA1, ABCG1, IRS2 and THBS1) in Yakutian cattle.
- The genes involved in the immune system are also associated with environmental adaptation.
- The eicosanoid metabolic process was previously found to be involved in the hibernation of brown bears (Ursusarctos) and indigenous peoples associated with seasonal changes. These findings indicate a convergent evolution that may have occurred in different mammalian species living in northern and sub‐arctic environments.
4. Phenotypic and Genotypic Characterisation of Ankole, Ntuku and Nganda cattle of Uganda – Dr. Behabura Generous Betunga, Makerere University
The Ugandan cattle herd is comprised of 93.3 percent of indigenous breeds and their crossbreeds which are mainly; Long-horned cattle of Uganda (Sanga) (Bostaurusindicus); Zenga breeds (Sanga and Zebu crosses); East African short-horn Zebu (Bosindicus). The OPTIBOV breeds of interest in Uganda are; Long horned Ankole cattle (South-Western Uganda); Nganda cattle (Central-Uganda) and Ntuku cattle (Mid-Western Uganda). The study aims to carry out phenotypic characterization for performance traits and draw a genomic growth curve for Ankole, Ntuku and Nganda cattle under different management systems for a period of 0 to 18 months in Uganda. It also aims to carry out genetic characterization and measure the genetic relationship between the Ankole, Ntuku and Nganda cattle in Uganda; and to assess selection techniques (natural and human mediated) of Ankole, Ntuku and Nganda cattle of Uganda. Meetings have been held with farmers and animals selected for sampling and samples collected for analysis.
Issues arising include;
- The Indigenous cattle breeds are at the threat of genetic erosion. There is need for Phenotypic & genotypic Characterization for the performance traits of the Ankole, Ntuku and Nganda
5. Investigating the production and adaptive traits of indigenous cattle to eastern Uganda ecosystems
Cattle is a valuable source of income, employment & a major source of nutrition to people in the East especially Karamoja and Bukedi in Tororo. Angoria Ting and Cheptoyoi are the indigenous cattle breeds in Karamoja: Karamajong women prefer rearing goats to cows. The study aims to;
- To phenotypically characterize the performance and adaptive traits of the Nkedi and Karimajong cattle
- To develop indices for assessing the productivity of the Nkedi and Karimajong cattle
- To assess status and risk of erosion of the two indigenous cattle genetic resources
Meeting with Makerere University Vice Chancellor
In the course of the seminar, the OPTIBOV project team paid a courtesy call on Makerere University Vice Chancellor, Prof. Barnabas Nawangwe who congratulated them upon winning the research grant.“As we celebrate 100 years of teaching, research and innovation, such projects are vital in pushing forward our agenda of transforming Makerere into a research-led University,” he noted, pledging to accord the researchers all the support they need to achieve the project objectives.
The project leader at Makerere University, Dr. Donald Kugonza expressed gratitude to the Vice Chancellor for the support he accorded the team in their bid for the project.

Africa Climate Collaborative: Masters & PhD Scholarship Announcement Academic Year 2026/2027
*****The two-day training, hosted by the College of Agricultural and Environmental Sciences (CAES) at Makerere University, was conducted under the auspices of the APPEAR Collaborative Research Project, ‘Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg).
The challenge of waste management in Uganda
Fecal Sludge Management (FSM) and Solid Waste Management (SWM) are essential for building healthy, resilient communities. However, in many parts of Uganda, these systems remain underdeveloped, leaving communities exposed to a wide range of complex challenges.
Improper handling and disposal of fecal sludge and solid waste pose both immediate and long-term public health risks, including the spread of waterborne diseases like cholera, typhoid, and dysentery. When human waste is not safely contained, treated, or disposed of, pathogens can contaminate water, food, and soil, disproportionately affecting vulnerable groups such as children and residents of informal settlements.
Environmentally, unmanaged waste degrades ecosystems, pollutes rivers and wetlands, and contributes to greenhouse gas emissions. Open dumping clogs drainage systems, heightening urban flood risks and facilitating disease transmission. Non-biodegradable materials, including plastics, can persist for decades, blocking waterways, harming wildlife, and weakening communities’ resilience to climate change.
The economic consequences are equally profound. Inefficient waste management undermines productivity by driving up healthcare costs, lowering property values, and limiting tourism and investment opportunities. Informal waste collection systems, often the only coping mechanism for many urban residents, fail to provide adequate protection for workers.
Given these intertwined health, environmental, and economic impacts, the burden of fecal sludge and solid waste in Uganda is not merely a municipal concern but a pressing national development issue. Urgent attention is required to invest in modern FSM and SWM infrastructure, promote behavioral change, and implement regulatory frameworks that ensure safe, sustainable, and inclusive waste management solutions. Without such interventions, the compounded risks to human well-being, ecosystems, and economic growth will continue to escalate.
Addressing the Challenge through the CPUg Project
The Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg) Project, a collaborative initiative between the CAES, the Institute of Water Quality and Resource Management at Vienna University of Technology in Austria, the Department of Environmental and Livelihood Support Systems at Mbarara University of Science and Technology (MUST), and the Uganda Red Cross Society, seeks to tackle Uganda’s most pressing challenges in waste management.
The project set out to explore circularity concepts, test a variety of techniques for utilizing dried fecal sludge, analyze plastic recovery from existing composting plants, and evaluate the social and economic viability of improved FSM and SWM and their influencing factors on regional communities. Supported under the Austrian Partnership Programme in Higher Education and Research for Development (APPEAR), the project aims to examine how best to optimize and integrate FSM and SWM in rural settings in Wakiso District, refugee settlements in Arua District, and Uganda in general.
In addition to the technical aspects, the socio-economic viability of improved fecal sludge and solid waste management is being evaluated in terms of affordability, perceptions, and the willingness to accept and utilize these products. The project aims to contribute towards reshaping Uganda’s landscape through integrated solutions, scientific rigor, and inclusive community engagement. It stands as a model for integrated development.
It is coordinated by Prof. Jeninah Karungi Tumutegyereize from the Department of Crop Science and Horticulture at CAES, Makerere University.
Two-Day Training on Integrated Fecal Sludge and Solid Waste Management
The College of Agricultural and Environmental Sciences at Makerere University, in collaboration with the Uganda Red Cross Society, Mbarara University of Science and Technology, and Vienna University of Technology, Austria, held a comprehensive two-day training on Integrated Fecal Sludge and Solid Waste Management.
The training, conducted on 30th-31st March 2026, at Makerere University was officially opened by the Principal of CAES, represented by Dr. Mildred Ochwo Ssemakula, Head of the Department of Crop Science and Horticulture. Participants included representatives from academia, the private sector, municipal authorities, service providers, and farmers.
The training programme aimed to equip personnel across the waste management value chain with the knowledge and skills to transform fecal sludge and solid waste into valuable, sustainable agricultural and economic resources. It covered topics such as occupational safety, waste management infrastructure, processing and post-treatment methods, composting, carbonization, material flow analysis, service gaps, and economic considerations in Greater Kampala. Participants were also trained in specialized software tools designed to enhance efficiency and manage waste-to-resource processes, promoting both environmental sustainability and economic viability.
Particular emphasis was placed on shifting perceptions of fecal sludge-based products among end users, mainly subsistence and commercial farmers.
Emerging Issues from the Training
- Weak fecal sludge management systems: Existing systems, particularly in refugee settlements, are inadequate.
- Public health risks: Improper sludge handling continues to threaten health – only 44% of fecal sludge is safely managed.
- Limited technical capacity: Practitioners need more training in safe handling and reuse technologies.
- Low adoption of resource recovery: Sludge-to-product innovations are underutilized.
- Environmental pollution: Untreated sludge contaminates soil, water, and surrounding ecosystems.
- Poor integration with agriculture: Opportunities for nutrient recycling are not fully exploited.
- Inadequate equipment: PPE, emptying tools, and treatment facilities are scarce.
- Low composting standards in Uganda: Composting often follows non-scientific methods.
- Behavioral and hygiene gaps: Handwashing and proper waste disposal practices remain weak.
- Underdeveloped waste-based value chains: Compost, briquettes, and fertilizers are not economically leveraged.
- High reliance on on-site sanitation: Sewer network coverage is below 10% in Greater Kampala.
- Insufficient emptying and collection services: Services are limited and costly.
- Limited private sector engagement: Public investment and private participation are inadequate.
- Treatment capacity and cost recovery challenges: Facilities are strained and revenue mechanisms weak.
- Low willingness or ability to pay: Users are reluctant or unable to afford improved services.
- Negative perceptions of fecal sludge products: Public attitudes hinder adoption.
- Regulatory and equity barriers: Awareness is limited, regulations are burdensome, and access is unequal.
Way Forward
Effective waste management is essential for public health, yet remains a significant challenge in Uganda, with few households able to empty their on-site sanitation facilities due to high costs. Experts emphasize the need for increased investment and prioritization of operator safety. Rigorous safety protocols and training are critical to safeguarding workers and ensuring sustainable operations.
Remarks by the CAES Leadership
On behalf of the Principal of CAES, Dr. Mildred Ochwo Ssemakula underscored Uganda’s immense potential to benefit from effective fecal sludge and solid waste management. “In an agriculture-dependent country, converting waste into organic fertilizer and other resources can significantly enhance productivity and generate substantial economic benefits. At the CAES, we are proud to collaborate and support initiatives like CPUg through innovative research and capacity-building programmes that directly address Uganda’s environmental challenges. I extend my sincere gratitude to the researchers and partners for their unwavering commitment to advancing research and environmental management. Makerere University highly values these collaborations, and together, we form a powerful coalition driving positive change in Uganda’s development.”
The CPUg project has contributed to capacity-building by training five PhD students, three from Makerere University and two from Vienna University of Technology, as well as three MSc students from Makerere University. The results are expected to improve knowledge in waste management and strengthen stakeholder capacity across the waste management value chain.

RUFS Project Team Enhances Capacity of Smallholder Farmers in Mbale City in Financial Management & Communication
Achieving lasting and sustainable success in agriculture goes far beyond planting and harvesting. It requires a diverse skill set, including financial literacy to manage budgets and make sound investment decisions, as well as effective record-keeping to track performance, inform operations, and identify opportunities for improvement. Equally important is strategic communication, which enables farmers to market their products, build brand visibility, and enhance profitability.
A strong understanding of group dynamics is also essential in helping farmers foster collaboration within cooperatives, community initiatives, and peer networks. By integrating these competencies, agricultural entrepreneurs can maximize productivity, optimize resource use, and build resilient enterprises capable of adapting to evolving environmental, economic, and social conditions.
Despite the vital role urban farmers play in ensuring food security, many still lack the technical knowledge and skills needed to optimize productivity. This gap limits output and undermines the profitability, efficiency, and long-term sustainability of their farming enterprises.
Addressing the Skills Gap Through Phase II of the RUFS Project
Phase II of the Resilient Urban Food Systems (RUFS) Project aims to address these challenges. Through hands-on training programmes in Mbale City and Kasese Municipality, the initiative seeks to equip urban farmers with practical knowledge, modern techniques, and adaptive strategies to improve productivity.
Led by Prof. Frank Mugagga from the Department of Geography, Geo-Informatics, and Climate Sciences at the College of Agricultural and Environmental Sciences (CAES), Makerere University, and supported by the AgriFoSe2030 Programme, the project focuses on strengthening urban food systems to withstand climate-related shocks such as floods and droughts. By promoting climate-smart agricultural practices, the initiative empowers farmers to sustain productive, profitable, and resilient operations, ultimately improving livelihoods and contributing to stable urban food supplies.
Training Sessions in Mbale City
To enhance their skills, the RUFS Project team held training sessions for smallholder farmers in Mbale City on 26th-27th March 2026. Hosted at the home of Hajji Siraji Kamulegeya, a mixed farmer in Nankusi Cell, Northern Division in Mbale City, the training provided a community-centered setting that encouraged active participation and peer learning.
A total of 25 farmers attended the training, which aimed to strengthen financial literacy and enhance overall farm management practices. The sessions covered essential topics such as effective bookkeeping, farmer group dynamics, systematic documentation of farm activities, and the strategic use of media to share knowledge and promote agricultural products and services.
Farmers actively engaged in the discussions, openly sharing their experiences and the challenges they encounter. Many confessed that they did not maintain proper financial records, citing limited knowledge of record-keeping practices, the busy schedules, and, in some cases, low motivation to adopt structured documentation systems.
Training in Financial Management
In a comprehensive training session focused on bookkeeping, Mr. Mbowa Henry from AidEnvironment, also a member of the RUFS Project, emphasized the critical importance of maintaining accurate, consistent, and systematically organized financial records. He noted that proper record-keeping not only improves financial management but also strengthens farm management and promotes long-term economic sustainability of farming enterprises.
He introduced the farmers to the core components of an effective record-keeping system, including cashbooks, receipt books, expenditure registers, and bank records, tools essential for monitoring income, tracking expenses, and evaluating overall performance.
He encouraged the participants to actively apply the knowledge acquired, stressing that consistent adoption of these practices would empower them to optimize their farm operations, enhance productivity, and secure sustainable financial growth for their agricultural ventures.
Managing Farmer Group Dynamics
In addition to financial skills, the RUFS Project team, led by Mr. Mbowa and Ms. Ritah Pavin Nakanjako, provided guidance on farmer group dynamics. Discussions centered on common challenges affecting collective farming and strategies to address them. Key challenges identified included the lack of shared goals, conflicting individual interests, weak saving culture, leadership gaps, unregistered or family-centered groups, low participation in group activities, uncoordinated initiatives, politicking, and limited financial management skills, all of which hinder the success of farmer groups. The trainers emphasized the importance of unity, clear objectives, and structured collaboration in strengthening group performance.
Climate Change Risks
Another significant topic of discussion was climate change and its devastating effects, as well as the social and hydrological histories, emphasizing the urgent need for adaptive strategies in agriculture. The Elgon region, which spans Eastern Uganda’s highlands and the foothills of Mount Elgon, is particularly vulnerable to extreme rainfall, flash floods, and landslides due to its steep terrain, heavy seasonal rains, and densely settled, erosion-prone slopes. Over the decades, such disasters, most notably in 1997-2004, 2010, 2018, 2022, and 2023, have resulted in displacement, destroyed livelihoods, damaged infrastructure, increased food insecurity, and heightened health risks.
During the training, farmers shared firsthand accounts of the devastating impacts of recurrent floods in the region. Facilitated by Mr. David Luswata, a Masters student supported by the project, and Ms. Patricia Kiggundu, a member of the project, the sessions offered a collaborative platform for participants to explore long-term, sustainable solutions aimed at reducing both the risks and economic losses associated with climate variability. As part of his Masters research on flood risk management among smallholder farmers in Mbale City, Mr. David Luswata engaged the farmers on the impact of floods on crops, livestock, property and livelihoods.
Documentation and Knowledge Sharing
The training also emphasized the critical role of documentation in effective farm management and knowledge sharing. Mr. Juma Wephukulu, a member of the RUFS Project and Chairperson of the Mbale City Food Systems Platform, offered detailed guidance on essential practices for recording day-to-day agricultural activities. Drawing from his own experience, Mr. Wephukulu authored a book chronicling his farming journey. Supported by RUFS, the publication serves as an educational guide and an inspirational resource, equipping other farmers with practical insights, strategies, and motivation to enhance productivity and resilience.
Communication and Media Engagement
Another distinctive feature of the training was its focus on communication and media engagement. Farmers were encouraged to leverage media platforms to amplify their voices and share their experiences with wider audiences. Mr. Wataba Shaban, a talk-show host at IUIU FM in Mbale City, led a simulated radio talk-show session, demonstrating effective techniques for communicating agricultural issues and providing participants with practical skills for public engagement.
Community Perspectives
Many of the factors driving climate change are the result of human activity, frequently stemming from unsustainable agricultural practices and improper construction methods. Representing the farming community, Hajji Siraji Kamulegeya called for more educational programmes and capacity-building initiatives to deepen understanding of the causes of climate change and strategies for mitigating its impact. He expressed gratitude to the funders and the project team for the interventions.
Addressing the participants, Mr. Munowa Hassan, LC1 Chairman of Nankusi Cell in Northern City Division, Mbale City appreciated Makerere University for its numerous initiatives aimed at empowering farmers and enhancing food security. He called for the expansion of such projects.
Action Planning
To translate knowledge into action, participants collectively developed a concrete action plan and a monitoring and evaluation framework to track progress, measure outcomes, and make necessary adjustments to achieve the desired impact.
A similar training will be conducted in Kasese Municipality.
