ABEN Charles
Participatory Land use governance and livelihoods in Awoja Watershed, Uganda
Mr. ABEN Charles examined the effects of participatory natural resource governance on livelihoods in Awoja watershed in Uganda. In particular, the study assessed the contribution of local people’s participation to policy implementation. Further, the effects of social, economic and political motivation on actor involvement in the participatory governance were examined. The results suggest that the effective participation was contingent on the motivation of different actors involved in watershed management. This study was funded by DANIDA and was supervised by Dr. Okiror, Prof. Jacob Agea and Dr. EsbernFriis Hansen.
ALEXANDER Noah Ruley Jane
Bioremediation of Petroleum Contaminated Soils using Native plants and their Rhizobacteria in the Sudd regions of South Sudan
Ms. ALEXANDER Noah Ruley Jane’s study was to enhance bioremediation of Petroleum Hydrocarbon-(PHC) Contaminated soils for increased agricultural productivity of the Sudd region of South Sudan. Specially, the study examined the native plant species abundant in petroleum hydrocarbon contaminated soil and optimal rate of cattle manure for enhancing phytoremediation of PHC contaminated soil in the region. In the results, PHC contamination at concentration of 7002 mgkg-1 detected as cultivated land from drilling points, was higher that the critical value of 5000mgkg soil (Sudan) and 5600mgkg (International). In sum, use of plant species namely H. Rufa, T. diversifolia and G. barbadense with 2 tha -1 of cattle-manure greatly improves bioremediation of PHC contaminated soils in the Sudd region of South Sudan. This study was funded by NORHED and was supervised by Dr Alice Amoding and Assoc. Prof John Baptist Tumuhairwe.
ALFONSE Leonard
The Role of Host Plants, Temperature and Natural Enemies in the Development, Survival and Reproduction of Edible Grasshopper Ruspolia differens (Orthoptera: Tettigoniidae)
Mr. ALFONSE Leonard studied the edible long-horned grasshopper (Ruspolia differens Servile) which is a very important source of food and income in East Africa. The insect is currently obtained from seasonally swarming wild populations which are erratic and declining. His study focused on factors limiting artificial mass rearing of R. differens; these factors include the confusion over the identity of the grasshopper, paucity of information on the natural diets, diseases, and the optimal temperature requirements. He identified edible grasshopper in Uganda as Ruspolia differens (Serville), which is a polyphagous with grasses preference to other plants. The study determined temperatures ranging from 28°C to 32°C as optimum for artificial rearing of R. differens. He further investigated that fungi and bacteria isolated from wild-collected grasshoppers were threats to artificial rearing of the insect. Glaurocara flava was the only identified parasitoid of R. differens. He also found that the inclusion of naturally occurring host plants into artificial diets can improve the survival and reproduction of R. differens. The results from this study can contribute to the development of efficient mass rearing protocols of R. differens. This study was funded by the International Centre of Insect Physiology and Ecology (icipe) and German Academic Exchange Service (DAAD), and supervised by Prof. Samuel Kyamanywa from Makerere University, and Dr. James P. Egonyu and Dr. Sevgan Subramanian from International Centre of Insect Physiology and Ecology (icipe).
KALANZI Fred
Socio-technological factors influencing smallholder farmers’ adaptation of agroforestry technologies in the eastern highlands of Uganda
Mr. KALANZI Fred studied smallholder farmers’ adaptation of agroforestry technologies in Uganda’s Eastern highlands to establish the rationale for smallholder farmers’ choices, use, and modification of agroforestry technologies. This followed a growing concern that despite the efforts to promote agroforestry technologies, smallholder farmers made contradictory choices and modified technologies in ways perceived by experts to compromise farm productivity and, consequently, food and income security. Results indicated that the technology’s perceived value in addressing the livelihood options of the smallholder farmers was the most critical sociotechnological factor influencing their choices of agroforestry technologies. The study also found that smallholder farmers made several modifications and generated their own practices with anticipated positive outcomes that made the agroforestry technologies more applicable to their unique contexts. The study suggests that while science may have a lot to offer to resource-poor smallholder farmers, their local knowledge and innovations should constitute building blocks in developing economically viable, environmentally compliant and socially acceptable agroforestry technologies. This study was supported by the German Academic Exchange Service (DAAD) through the World Agroforestry Centre (ICRAF) and NARO and supervised by Dr. Prossy Isubikalu, Dr. Florence Birungi Kyazze and Dr. Lawrence J.B. Orikiriza.
KALULE Wamala Stephen
Farmer Learning Behaviours: A Case of the student-to-farmer university outreach of Gulu University in Uganda
Mr. KALULE Wamala Stephen utilized a sample of 283 host farmers of the student-to-famer outreach of Gulu University to examine the influence of psychosocial factors on farmer learning behaviour. The results show that the most important and positive facilitating condition for farmer learning behaviour was faculty supervision support to students. For the motivational factors, satisfaction of relatedness learning needs and formation of learning intentions were the positive and significant predictors farmer learning behaviour. This study funded by RUFORUM and was supervised by Dr. Haroon Sseguya, Assoc Prof. Duncan Ogeng and Dr. Gabriel Karubanga.
KYALLO Martina
Identification and Characterization of Cassava Mosaic Begomovirus-like viruses Associated with Non Cassava Plants in Kenya
Ms. KYALLO Martina study was on sustainable management of cassava mosaic disease by determining the role non-cassave hosts of Cassava Mosaic Disease (CMD) like viruses and their associated viruses play in the epidemiology of CMD in Kenya. The study identified M. Lutea as a potential alternative host for East African Cassava Mosaic Virus in Uganda revealing the adaptive potential for the virus and expanding our current knowledge of the host range of CMD in Kenya. This study was funded by Bill & Melinda Gates Foundation and was supervised by Dr. Mildred Ochwa Ssemakula and Dr. Robert A. Skilton.
LOGA Dorcas Elizabeth
Enhancing Group Sustainability and Innovativeness of Youth in Agriculture; a Comparative Study of Government and Non-government Interventions in Mid-western Uganda.
Ms. LOGA Dorcas Elizabeth studied how government and Non-Government agencies support youth groups in mid-western Uganda to engage in agriculture. The focus was on discovering the conceptual underpinnings that inform and shape the nature of support, enhancing the sustainability of youth groups, and youth innovativeness. The study revealed that government support is premised on the assumption that the youth lack capital, therefore focusing on capitalization through credit and free input provision; while the NGO support is premised on the assumption that youth lack entrepreneurial skills and extension services, and therefore focused on capacity building. The NGO-supported groups were more likely to be sustainable than the Government supported groups. Amidst numerous challenges, the groups post a higher score of innovativeness with an average innovation index of 0.536 reflecting a high potential for youth to revolutionize agriculture. Strengthening coordination to ensure cooperation and complementarity among interventions can enhance the innovativeness and sustainability of youth groups, and make agriculture more gainful. The study was funded by DAAD and Carnegie Corporation of the New York through RUFORUM; and supervised by Assoc. Professor Paul Kibwika and Dr. Florence Birungi Kyazze.
MAWA Christopher
Effects of community-based forest management initiatives on conservation and rural livelihoods in mid-western Uganda
Mr. MAWA Christopher examined the socio-ecological outcomes of community-based forest management initiatives in mid-western Uganda. The study found that positive social and ecological outcomes were simultaneously produced in areas where local community members were either actively co-managing forest resources with the state or were being supported by non-governmental organizations to formally manage and own them. Specifically, the initiatives enhanced community access to legally-sourced forest resources for both subsistence and cash. Additionally, households that had members belonging to conservation groups were more likely to benefit from alternative livelihood schemes promoted by state and non-state actors in the area. However, these alternative livelihood schemes mostly encouraged survival-led as opposed to accumulation-led livelihood diversification pathways. This study was funded by NORHED and was supervised by Prof. David Mwesigye Tumusiime and Assoc. Prof Fred Babweteera.
MUKHONGO Wilhem Ruth
Abbuscular Mycorrhizal Fungi for Enhanced Nutrient and Moisture Utilization in Sweet Potato Production
Mr. MUKHONGO Wilhem Ruth investigated the composition and spore abundance of Abbuscular Mycorrhizal Fungi (AMF) in sweet potatoes producing regions in Uganda for local inoculum production. Further, the study sought to determine the efficacy of the native AMF and phosphorus on growth and yield of sweet potatoes. In the findings, the assessment of the composition and spore abundance of AMF in sweet potatoes zones yielded a similarity in the AMF communities with Glomus and Acaulospora species accounting for 38% and 20% respectively. This study was supervised by Assoc. Prof. John Baptist Tumuhairwe, Dr. Peter Ebanyat and Dr. Cargele Masso.
MULINDE Catherine
Climate Adaptation and Crop Productivity in Coffee-Based Farming Systems of Uganda
Ms. MULINDE Catherine focused on determining the most sustainable climate adaptation practices that are likely to increase current and future crop productivity, and mitigate climate vulnerabilities in Arabica and Robusta coffee-based farming systems of Uganda by 2040. She adopted qualitative, quantitative and modeling approaches in assessing climatic-crop suitability, adoption-drivers and effectiveness of major adaptation practices. Coffee and banana were revealed as more vulnerable to climate change than maize and beans in eastern, central and western Uganda; and that agroforestry, inorganic fertilizer, organic manure, mulch, trenches and soil bunds can potentially reduce crop yield losses especially if future climate becomes drier than wetter. The study recommends the promotion of these adaptation practices with an agile extension service considering the diverse adaptation
needs of coffee-farmers rather than ‘one-size-fit-all’ adaptation strategies; identification of efficient on-farm water-draining technologies; and bioengineering of crop varieties adaptive to wetter-conditions across various altitudes. This study was supervised by Prof. Majaliwa
Mwanjalolo and Dr. Revocatus Twinomuhangi, and funded by USAID.
NAKITTO Aisha Musaazi Sebunya
Solanum anguivi Lam. fruits’ nutritional quality and potential effect on type 2 diabetes mellitus.
Ms. NAKITTO Aisha Musaazi Sebunya investigated the morphological characteristics, bioactive compound contents (BCC) and antioxidant activity (AA) of fourteen accessions of Solanum anguivi Lam. The impact of various ripeness stages and thermal treatments on the BCC and AA of Solanum anguivi Lam. fruits (SALF) was determined, where the unripe stage and boiling exhibited the highest AA. Further, the potential of dietary SALF to prevent and manage type 2 diabetes mellitus (T2DM)-like phenotypes was investigated using the fruit fly, Drosophila melanogaster (D. melanogaster) model organism. D. melanogaster has been previously shown to develop a T2DM-like phenotype upon high-sugar diet (HSD) intake. The study showed for the first time that dietary SALF lowers HSD-induced glucose levels in D. melanogaster, which was not mediated through an up-regulation of central genes (Srl, dIlp3 and dIlp6) of the fly’s energy metabolism. Simultaneously, dietary SALF increased the flies’ survival, thus suggesting a protective effect of SALF against premature death associated with a T2DM-like phenotype. Dietary SALF may therefore help prevent and manage T2DM in humans. This study was funded by the DAAD and FTBIC and was supervised by Prof. John Muyonga, Prof. Anika Wagner and Assoc. Prof Yusuf Byaruhanga.
NDAULA Sulaiman
Psychosocial factors in rural smallholder farmers’ decision to accept orange-fleshed sweet potato in Uganda
Mr. NDAULA Sulaiman studied the acceptance of orange-fleshed sweet potato (OFSP) within households that already grow White-fleshed sweet potato (WFSP). With vitamin A deficiency enduring as a major public health concern in many developing countries, OFSP continues to be promoted as a food-based alleviation strategy for the deficiency. This study sought to enhance understanding of the role of rural smallholder farmers’ socio-cognitive contexts in OFSP acceptance in Uganda. The study revealed that farmers at the various stages of the OFSP cultivation process (under consideration, trial, or maintenance) differ in the belief sets they held about OFSP relative to the WFSP sweet potato varieties. Also, sustained OFSP cultivation was enhanced by social pressure, farmers’ valuation of their capability to cultivate OFSP as compared to cultivating WFSP and health-related risk perceptions. Through compliance and conformity to peer pressure, farmers created a cycle of low cultivation intensity that led to limited access to vines, low appreciation of relative advantage of OFSP over WFSP and the attendant cultivation defections. This study points to a cardinal role for processes that create supportive social and cognitive environments for the acceptance of bio-fortified technologies such as the orange-fleshed sweet potato. This study was funded by DAAD and supervised by Dr. Frank Matsiko, Dr. Richard Miiro, and Dr. Haroon Sseguya.
OBUA Tonny
Genetic Improvement of Nutritional Traits and Yield of Tropical Soybean in Uganda
Mr. OBUA Tonny investigated the genetic diversity and population structure of 89 tropical soybean germplasm, and determined the variability of nutritional traits of 52 soybean core collections from diverse sources. He further conducted a genome-wide association study based on 92 soybean genotypes, as well as determination of environmental effect on protein content and yield in soybean. The results showed that the genetic diversity among the studied germplasm was low, and the phylogenetic tree and Principal Component Analysis grouped the 89 genotypes into three major clusters. The low genetic diversity could be attributed to the cleistogomous nature of soybean and the sample of genotypes used that were mainly released varieties and advanced breeding lines; that have been genetically fixed at all loci in regard to general consumer preferences after many cycles of selections. Low diversity in the studied germplasm pool is a reflection of genetic erosion of the existing germplasm pool, which calls for widening of the current germpalsm base. The study further identified several soybean genotypes that protein and oil content above the reported averages. Total oil content varied significantly between origins with genotypes from Zimbabwe showing the highest mean of 20.13% while those from Taiwan had the lowest mean of 18.3%. The study was funded by Soybean Africa Limited, Makerere University Center for Soybean Improvement and Development, Biosciences Eastern and Central Africa – International Livestock Research Institute Hub; and was supervised by Prof. Phinehas Tukamuhabwa and Dr. Thomas L. Odong.
OCHIENG Hannington
Biological assessment of River Aturukuku in Tororo, Uganda: a tropical river with potential environmental threats from its catchment
Mr. OCHIENG Hannington undertook a biological assessment of River Aturukuku in order to contribute towards its conservation and sustainable utilisation by the riparian communities. His research compared the utility of two macroinvertebrate based Biological Monitoring Working Party indices, from England (temperate region) and Costa Rica (tropical region) for assessing water quality, and explored the assemblages of benthic macroinvertebrates and diatoms along River Aturukuku. His research showed that the two foreign biomonitoring indices could not separate sites based on pollution gradients, attributable to biogeographical differences in environmental conditions and pollution tolerances among macroinvertebrates. The diversity of benthic macroinvertebrates and diatoms in the river was low, with pollution-tolerant taxa dominating. The development of indigenous biotic index for Uganda and specific mitigation measures for conservation of the entire river for sustainable utilisation is recommended. The study was funded by the National Geographic Society and was supervised by Prof. James Okot-Okumu and Dr. Robinson Odong.
SYOFUNA Agatha
Prevalence and impact of stem canker diseases on Eucalyptus grandis and selected Hybrid clones in Uganda
Ms. SYOFUNA Agatha studied the prevalence and impact of stem canker diseases on Eucalyptus grandis and selected Hybrid clones in Uganda. This was based on the background that there is a drive for re-afforestation and a high timber demand in the country, both of which are being solved by extensive plantation development. The study revealed that Eucalyptus plantations are threatened by Botryosphaeria and Teratosphaeria canker diseases throughout the Country mostly in the Central, Eastern and Albertine regions. Five species of Botryosphaeriaceae were identified based on multi-locus phylogenies (ITS and β-tubulin). Pathogenicity tests using species of Botrosphaeriaceae and Teratosphaeria revealed variation in susceptibility of Eucalyptus grandis and selected hybrid clones, suggesting that disease-tolerant Eucalyptus genotypes could be selected for disease management. Furthermore, an assessment of the anatomical, physical, and mechanical properties, revealed brittle failure and high shrinkage in wood from diseased trees, indicating that it is not suitable for some construction applications and should be used with caution. The study was funded by African Development Bank and DAAD, and supervised by Dr Grace Nakabonge and Prof. Abwoli Y. Banana.
TURYAHIKAYO Willy
Network governance dynamics that influence the generation and implementation of innovative activities within the Agricultural Innovation Platforms.
Mr. TURYAHIKAYO Willy investigated the network governance dynamics that influence the generation and implementation of innovative activities within the Agricultural Innovation Platforms. The study findings showed that the level and structure of interactions have got a profound effect on generation and implementation of new ideas within the agricultural innovation platforms. However, owing to the informal nature of networks, this study revealed stringent collective sanctions in the IPs can negatively impact the innovative activities. The study recommends increased actor interactions in terms of duration and frequency of interactions between actors within the platforms. This study was funded by the German Academic Exchange Service (DAAD), and supervised by Dr. Frank B. Matsiko, Dr. John J. Okiror, Dr. Richard F. Miiro and Prof. Jon Hanf.

3rd GORILLA Conference Off to a Reflective Start
Published
2 days agoon
December 5, 2024The 3rd International Conference on Geographical Science for Resilient Communities, Ecosystems and Livelihoods under Global Environmental Change (GORILLA) got off to a reflective start on Wednesday 4th December 2024 as delegates recognized that only 17% of the Sustainable Development Goals (SDGs) targets are on track to be achieved by 2030. Officially presided over by the State Minister for Environment, Hon. Beatrice Atim Anywar the opening ceremony was also graced by His Royal Highness Jude Mike Mudoma, the Umukhukha of Bamasaba Cultural Institution, Inzu Ya Masaba.
Organised by the College of Agricultural and Environmental Sciences (CAES), Makerere University in partnership with the International Geographical Union (IGU) Commission of Biogeography and Biodiversity, the IGU Commission on African Studies, Uganda Geographical Association, and the International Association of Landscape Ecology (IALE) African Chapter, the 3rd GORILLA Conference was aimed at contributing to the realization of the Global Development Agenda 2030. Specifically, the conference sought to provide a platform for conceptual, empirical, and theoretical conversations to address how science can help in bridging gaps and addressing sustainable development deficits.
Overview of the Conference
The National Organising Committee Chair and Deputy Principal College of Agricultural and Environmental Sciences (CAES), Assoc. Prof. Yazidhi Bamutaze and his Co-Chair Dr. Jerome Ssebaduka Lugimira from the National Environment Management Authority (NEMA) noted that the 2024 Conference attracted participants from over 50 countries. Whereas the first edition of the conference in 2020 attracted 114 participants, the second edition in 2022 attracted 163 participants and this year’s attracted 375 abstract submissions.
The Conference featured twelve (12) themes namely: 1) Geographies of Climate Change, Climate Justice and Just Transition, Spaces and patterns; 2) Biodiversity Informatics, Sustainable Ecosystems, Landscapes and People; 3) Green Growth and Transitions to Land Degradation Neutrality and Net Zero; 4) Water Governance and Transitions to Land Degradation Neutrality and Net Zero; 5) Interconnected Geo-hazards and Disasters in a Changing World; 6) Polycrisis: Migration, Displacement, Conflict and Humanitarianism; 7) The changing Geography of Agrifood Systems; 8) Nature Best solutions for inclusive and equitable development; 9) Emerging and novel technologies for societal resilience; 10) Sustainable Cities and Urban Systems in SSA; 11) Geographies of Energy and Energy Transitions; and 12) Environment and Health.
“What is quite striking is that the area of Biodiversity Informatics, Sustainable Ecosystems, Landscapes and People attracted the highest number of submissions, and SDG 13: Climate action turned out to be the most attractive but, you also have issues to do with SDG 15: Life on Land and SDG 14: Life Below Water” Prof. Bamutaze reported.
He noted that the Conference was desirous of taking stock of technologies, knowledge, innovations and all undertakings at local levels that are imperative in ensuring that the journey to achieving SDGs prioritizes safety. Staying with the SDGs, Prof. Bamutaze noted that despite the large volume of work published by scientists, there was a big gap regarding the utility of this work by policies.
Prof. Bamutaze shared that the Conference was preceded by trainings on how to harness Artificial Intelligence in ongoing work on biodiversity, a Hackathon aimed at tapping into Earth Observation data, a Summer School on Community Resilience and Geo-visualization with field visits to the Mt. Elgon catchment area as well as trainings on scientific writing.
Co-creation key to Social Transformation
In his remarks, the Acting Vice Chancellor, Prof. Buyinza Mukadasi noted that the glaring sustainable development deficits call for accelerated actions from institutions in Africa, especially since the continent’s contribution to global knowledge output stands at less than 5%.
“We have an obligation to co-create knowledge tailored to environmental and social contexts that is actionable at scale; provide key evidence to policy makers and practitioners to enable them undertake grassroots actions and interventions; as well as co-create innovations that can catalyse social transformation” he shared.
Prof. Buyinza informed conference participants of Makerere’s continued investment in building partnerships that advance national and global sustainability, with specific focus on PhD training so as to improve annual knowledge output from Africa. “Under the African Research Universities Alliance (ARUA), we have defined core areas/disciplines in which we will collaboratively be churning out 1,000 PhDs annually.”
The Role of Traditional Ecological Knowledge (TEK) Systems
Addressing the conference, the Umukhukha Jude Mike Mudoma admitted that he was no stranger to academia, having been in research circles for the last 28 years as an environmental scientist. He therefore appreciated the opportunity to participate in the conference, especially at a time when the geographical area covered by his kingdom is in need of restoration to alleviate recurring natural disasters such as landslides.
The Umukhukha defined TEK as knowledge, beliefs and practices that indigenous people have developed over centuries to manage and conserve natural resources. “Our TEK is based on observations, experiments and spiritual connections with the natural world,” he noted, further adding “For example, our ancestors developed agroforestry systems that mimicked the natural forest ecosystem, promoting diversity and soil fertility.”
HRH Jude Mike Mudoma singled out rainwater harvesting techniques and extensive knowledge of medicinal plants that has been passed down through generations as other examples of TEK. He further outlined the Bamasaba Clan-based Governance that provides a framework for decision making, conflict resolution and resource management as well as the Council of Elders that provides guidance and oversight of matters related to natural resource management, cultural heritage and community development as traditional institutions that play vital roles in TEK. He equally singled out traditional ceremonies such as Imbalu (circumcision) as gatherings that promote cultural heritage and provide opportunities for community members to discuss pertinent issues.
“I want to implore you people that we should help our scientists to document and preserve our TEK for future generations” appealed the Umukhukha to conference participants. “Secondly I want support for community-led initiatives. The whole of Mt. Elgon range is now declared a disaster area because we ourselves have destroyed the environment and recently we lost over 190 people who were buried and we have only recovered 25” added H.R.H. Mudoma.
He further appealed to participants at the 3rd GORILLA Conference to support the Mt. Elgon region in areas of disaster risk reduction and management as well as environmental conservation and restoration. “Another area is climate change adaptation and mitigation and of course when these are done, we cannot forget community-based initiatives for sustainable livelihoods, which I have seen is part of your discussions here and I want to benefit from your expertise.”
Timing of 3rd GORILLA Conference Key
Following the moment of silence observed in respect of the recent Mt. Elgon landslide victims, the Chief Guest, Hon. Beatrice Atim Anywar lauded the timing of the conference as befitting, especially as it coincides with ongoing local, regional and global efforts to address pressing sustainability challenges and transitions towards a green world.
Referring to the 29th Annual United Nations Climate Change Conference (COP29) she attended in Baku, Azerbaijan, Hon. Anywar took note of the reinforced global climate action through an annual commitment of US$300billion in climate financing. The funding, she added, will help vulnerable nations adapt to climate change and embrace renewable energy.
“As we sit here, I want us to think, how can we prepare as a country for the carbon credit and carbon markets? It is a new discovery, it is a new source of financing, how prepared are we?” Hon. Anywar asked her audience. “How do we have it clearly explained to our people the difference and benefits between organic agriculture and genetically engineered agriculture?” she further added.
The State Minister further urged the academia to always ensure that the community is brought on board during events where research is being disseminated. “In order to benefit them, they must be part of us, and they must understand what we are doing; they shouldn’t be suspicious” she added.
Hon. Anywar concluded by urging participants at the 3rd GORILLA Conference to use the platform to together cultivate a cohesive knowledge ecosystem that drives forward Agenda 2030, “and this should include the Traditional Ecological Knowledge (TEK) as stipulated by H.R.H. the Umukhukha” she emphasised.
Insight into Remote Sensing in Africa
The opening ceremony was followed by a Keynote Address delivered by Prof. Moses Azong Cho, Professor at the University of Pretoria and Chief Researcher at the Council for Scientific and Industrial Research (CSIR), South Africa. His presentation titled Managing Remote Sensing Technology for Assessing Biodiversity sought to describe biodiversity in the context of remote sensing, illustrate some of the work that has been done in the field, and touch on the new era of space borne remote sensing for biodiversity assessment.
“I tell you my African colleagues, if you think that remote sensing in Africa is simpler, you’re mistaken. You’re dealing with a more complex environment; forests are more diverse, savannah landscapes are very diverse and rural areas are quite heterogeneous – the mosaic of different landscape forms and types is crazy on the continent. So, we rather need more complicated remote sensing tools to be able to provide the kind of information that’s required on the continent” narrated Prof. Cho of his experience.
He equally urged scientists and their teams to mind the way they communicate with stakeholders when they take remote sensing products to the communities. “Try to understand the stakeholders and ensure that you will sit down and have the language to convince them what you’re offering can actually help them improve on their services and decision making.”
Prof. Cho who earlier described himself as a Bio-Geoinformatician; one who combines knowledge of Biology, Ecology, Geography, Remote Sensing, and Geographical Information Science to understand biodiversity and ecological phenomena, found himself gradually becoming an Agro-Geoinformatician. This was after their rich biodiversity information and data maps could hardly attract any funding despite the well-articulated need to conserve the environment.
“Our people are dying of hunger, we need to produce food” prospective funders would respond, later adding “and you are saying we should conserve the rich landscape, with 60% of fertile uncultivated land present on the continent of Africa?”
This light bulb moment from this response led to the development by Prof. Cho and his team, of systems that can enable farmers to effectively use small parcels of land to cultivate food, as opposed to nomadic farming whereby exhausted soils are abandoned for opening of previously uncultivated lands, often rich in biodiversity. Smart farming, digital farming, satellite farming, conservation farming and regenerative agriculture are names that have come to define these systems.
“Remote sensing can play a vital role in these systems and so we actually changed the name of our research group from Earth Observation Group to Precision Agriculture Research Group and suddenly, we started getting lots of traction with both Government and Private Sector because we packaged the information that we generate using our remote sensing models into a software called the Precision Agriculture Information System” Prof. Cho shared.
The software enables farmers to access information on soil conditions and the health of their crops on a weekly basis. “We have developed models that can very accurately predict soil organic content, soil nitrogen content, pH of the soil, and soil moisture, because we have taken time to interpret the spectral information” Prof. Cho triumphantly shared.
On the new era of space borne remote sensing that is upon us, Prof. Cho shared that this will provide even higher resolution imagery that can monitor crop stress and relatedly, the impacts of climate change on ecosystems. “NASA is working on new programmes; there’s the PANGEA programme, where I am a Committee Member, where we want to deploy these new sensors within tropical forests in Congo, Cameroon and Ghana to see how we can assess tropical forest biodiversity and change with respect to global changes.”
Furthermore, developments such as the new synthetic radar signal that is not sensitive to clouds enables acquisition of reflected microwave energy both during the day and night, which is critical for the humid tropical regions that experience a lot of cloud cover.
“We need to prepare so that we are not left behind, particularly those of us on the African continent. We need to develop our infrastructure, and cloud computing platforms. We need to develop the capacity amongst our youth when it comes to big data analytics” concluded Prof. Cho.
Summing it all up
The captivating keynote address was followed by a panel discussion that debated; what academia is doing to ensure that it breaks free from the “Ivory Tower” mentality, and how academia and research institutions can contribute to processes that lead to the attainment of SDGs. Furthermore, the panel discussed; what universities can learn from Civil Society Organisations (CSOs), what CSOs can do to support Government’s drive to achieve SDGs, and the communities’ experience of progress made on SDG3: Good Health and Wellbeing, SDG6: Clean Water and Sanitation, and SDG13: Climate Action.
Panelists included Assoc. Prof. Justine Namaalwa- Head Department of Environment Management, CAES, Mr. Ronald Kaggwa-National Planning Authority (NPA), Ms. Pauline Nantongo Kalunda- Executive Director ECOTRUST – the Environmental Conservation Trust of Uganda, Dr. Harriet Rachel Kagoya- Director of Operations Uganda Red Cross Society (URCS) and Mr. Moses Nadiope-Chairman/Coordinator Kasubi Parish Local Community Development Initiative.

Call for applications for four PhD positions
Makerere University Regional Centre for Crop Improvement (MaRCCI),
Makerere University & The Norwegian University of Life Sciences
1st December 2024
Background
One of the 17 Sustainable Development Goals is to attain zero hunger by 2030, but whether most of African countries are on track towards this ideal is questionable, While the continent is projected to be the most populous one by the year 2100, a critical mass of its population is already food-insecure, a situation that is being exacerbated by climate change and environmental degradations.
Coping with these complex issues require adopting an integrated approach of disrupting overreliance on major commodities such as rice, maize, and wheat over the opportunity crops also called neglected and underutilized species (NUS). These species are nutrient-dense, hold the ability to help diversify both the agricultural and the food system and constitute a security net that filters pest and disease-caused damages3. However, the current organizational architecture of these species suggests they cannot compete with the so-called major crops because of several limitations including: the paucity of established data (e.g., production statistics, nutritional data), the poorly organized value chains (when they exist), and the low flow of knowledge, technology and products among the value chains actors, among others.
The ‘Building Opportunities for Lesser-known Diversity in Edible Resources’ (BOLDER) project, an extended work package of the larger ‘Biodiversity for Opportunity, Livelihoods and Development’ (BOLD) initiative is designed to promote opportunity crops in West African countries (Benin and Ghana) and East African countries (Uganda and Tanzania). BOLDER is a three-phase project dedicated to improving nutritional security in West and East Africa through the increased use and value of nutritious but currently underutilized, climate-resilient and environmentally friendly crops.
BOLDER will work towards exhibiting the potential for four opportunity crops in each of the four target countries and operates through three pillars namely: i) increasing the availability of the target opportunity crops diversity; ii) improving the production, marketing, and/or consumption of these opportunity crops, and iii) enhancing the capacity of researchers, practitioners, and food system actors to improve use and value of opportunity crops. Under this third pillar, a total of eight PhDs students (four in East Africa and four in West Africa) will be trained in Plant Sciences, Food Systems and Value Chain R4D. The PhD training in East Africa will be coordinated by MaRCCI, Makerere University, in collaboration with The Norwegian University of Life Sciences (NMBU).
Objectives of this call
This call for applications is open to citizens of Uganda and Tanzania to fill four PhD positions: two in Plant Sciences and two in Food Systems.
All four PhD candidates will register at Makerere University and will be supervised by a panel of scientists from MaRCCI, Department of Agricultural Production (DAP), Department of Plant Sciences, Microbiology and Biotechnology (PMB), and Department of Agribusiness & Natural Resource Economics (DANRE), The Norwegian University of Life Sciences (NMBU), The Alliance of Bioversity International and CIAT (ABC) and the World Vegetable Center (World Veg). Decisions about supervisory arrangements will be made based on research proposals of successful applicants.
Expectations from the recruited PhD candidates
The two Plant Science PhD candidates through their research will contribute to the BOLDER project output of characterizing opportunity crops’ diversity and participatory evaluations using the TRICOT approach, while the other two students will contribute to the BOLDER Output of deepening our understanding of opportunity crops food systems and value chains and pursuing opportunities for greater contributions to livelihoods and diets.
Plant Science Applicants
The two Plant Science PhD student research projects will focus on the genetic and low-cost phenotypic characterization of farmer collection/landraces, genebank, and breeding materials for opportunity crops (stakeholder selected opportunity crops for Uganda i.e. cowpea, pumpkin, and amaranth, while for Tanzania the pre-selected crops are Bambara groundnuts and sweet potato). The aim is to generate key information on the adaptive traits of opportunity crops, their nutritional value, and their suitability for different uses, such as food, feed, and fiber. The research will further identify unique genotypes and suitable breeding strategies for improving desirable traits.
Another aspect of the PhD research will involve conducting a performance evaluation of opportunity crops traits using the citizen science approach known as triadic comparisons of technology options (tricot). This approach applies to an incomplete block design to assign randomized incomplete blocks of three technologies (out of larger number) to many farmers from different gender and socioeconomic groups for on-farm assessment in diverse agro-ecologies. Combining this approach with digital tools makes it possible to obtain insights for both local adaptation and a scale of reach compared to earlier participatory plant breeding/variety selection approaches. This approach has shown promising results recently and it is on the scale in East Africa. The planned PhD research and training will be critical in building local capacity for demand-led breeding and evaluation of opportunity crops using data science at a low cost in East Africa. The goal is to improve the identification and selection of opportunity crops varieties with desirable traits, ultimately leading to the mainstreaming of NUS in sustainable food systems in Africa.
In summary, the PhD projects will combine genomics research and on-farm tricot experiments and provide evidence on how this approach can lead to a demand-driven breeding of different NUS, accelerate trait discovery for climate adaptation, strengthen seed systems, increase use of NUS, and create links to the value chain.
We invite PhD research concept note focusing on one of the pre-selected crops in one of the countries.
Food Systems Applicants
The two PhD research projects in Food Systems will focus on two main areas, also in relation to the selected species for the two countries. The first area will be value chains of the focal crops. Specifically, this aspect of the research will characterize the current state of value chains and explore bottlenecks, inefficiencies, and opportunities, including related to production, processing, distribution, marketing and consumption.
The research will also analyze the demand for opportunity crop products, the preferences and behaviors of consumers (including consumer preference trials using the tricot approach), and the most effective interventions for promoting opportunity crops in food systems.
The second area of focus in Food Systems will be the nexus between traditional knowledge on the cultivation and consumption of NUS (local food culture) and the broader political and economic factors affecting the development and promotion of opportunity crops in inclusive and equitable food systems. This project will examine the interconnection between the cultural practices of local communities regarding the cultivation and consumption of opportunity crops and the wider economic and political systems that shape the food systems in which these communities operate. On the one hand, local food cultures have evolved over generations and reflect the specific ecological, social, and cultural contexts in which they are situated. This traditional knowledge often includes cultivation practices, processing methods, and culinary traditions associated with opportunity crops. Such traditional knowledge is important for
understanding opportunity crops nutritional, cultural, and economic significance and how they can be integrated into sustainable food systems. On the other hand, development and promotion of opportunity crops in inclusive and equitable food systems is shaped by broader political and economic factors, including government policies, global trade agreements, corporate influence, and consumer preferences. These factors can create barriers to the promotion and development of opportunity crops, which can impact the livelihoods of smallholder farmers and the availability of diverse and nutritious foods for local communities. By understanding these factors, the research will aim to identify opportunities to promote the development and promotion of opportunity crops in inclusive and equitable food systems in Africa.
We invite PhD research concept note that addresses one of the two food system areas outlined above. The proposal can focus on or several of the pre-selected crops in one or both of the countries.
