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.

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.

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.
