(Palgrave Macmillan, 2024-12) Ashepet, Mercy Gloria; Vranken, Liesbet; Michellier, Caroline; Dewitte, Olivier; Mutyebere, Rodgers; Kabaseke, Clovis; Twongyirwe, Ronald; Kanyiginya, Violet; Kagoro-Rugunda, Grace; Huyse, Tine; Jacobs, Liesbet
Citizen science (CS) is gaining global recognition for its potential to democratize and boost scientific research. As such, understanding why people contribute their time, energy, and skills to CS and why they (dis)continue their involvement is crucial. While several CS studies draw from existing theoretical frameworks in the psychology and volunteering fields to understand motivations, adapting these frameworks to CS research is still lagging and applications in the Global South remain limited. Here we investigated the reliability of two commonly applied psychometric tests, the Volunteer Functions Inventory (VFI) and the Theory of Planned Behaviour (TPB), to understand participant motivations and behaviour, in two CS networks in southwest Uganda, one addressing snail-borne diseases and another focused on natural hazards. Data was collected using a semi-structured questionnaire administered to the CS participants and a control group that consisted of candidate citizen scientists, under group and individual interview settings. Cronbach’s alpha, as an a priori measure of reliability, indicated moderate to low reliability for the VFI and TPB factors per CS network per interview setting. With evidence of highly skewed distributions, non-unidimensional data, correlated errors and lack of tau-equivalence, alpha’s underlying assumptions were often violated. More robust measures, McDonald’s omega and Greatest lower bound, generally showed higher reliability but confirmed overall patterns with VFI factors systematically scoring higher, and some TPB factors—perceived behavioural control, intention, self-identity, and moral obligation—scoring lower. Metadata analysis revealed that most problematic items often had weak item–total correlations. We propose that alpha should not be reported blindly without paying heed to the nature of the test, the assumptions, and the items comprising it. Additionally, we recommend caution when adopting existing theoretical frameworks to CS research and propose the development and validation of context-specific psychometric tests tailored to the unique CS landscape, especially for the Global South.

Disaster risk reduction measures and farmers choices: a discrete choice experiment in Uganda
(Informa UK Limited, 2024-10-15) Mutyebere, Rodgers; Vanermen, Iris; Ruymbeke, Kato Van; Nkurikiye, Jean Bosco; Twongyirwe, Ronald; Sekajugo, John; Kabaseke, Clovis; Kanyiginya, Violet; Kagoro-Rugunda, Grace; Kervyn, Matthieu; Vranken, Liesbet
Climate change induces high and erratic rainfall which triggers landslides and floods. With the increasing population and food needs, households in mountainous, densely populated areas turn fragile ecosystems into farms. This exacerbates landslide and flood risks requiring Disaster Risk Reduction (DRR) measures. Tree planting and diversion channels are among the recommended measures for farmers but their adoption remains low. Current studies assessing barriers to adoption ignore farmers’ opinions regarding the kind of trees or diversion channels preferred. We apply a Discrete Choice Experiment to evaluate how information delivered through videos impacts preferences for the DRR measures. Plot-level data were collected from 319 farmers from Kasese, Bundibugyo, Bushenyi and Buhweju in Uganda – districts prone to landslides and floods. The mixed logit model reveals a general preference for risk-reducing attributes of DRR measures. Using the conditional logit model to analyze split samples reveals that information influences preferences for tree planting, while preferences for diversion channels were hardly changed. Plot characteristics did not strongly explain the differences in preferences. Our study indicates that information specific to DRR measures in extension programmes would increase the adoption of such measures.
Does the farmer’s social information network matter? Explaining adoption behavior for disaster risk 2 reduction measures using the theory of planned behavior
(Theory of Planned Behavior, 2022) Mutyebere, Rodgers; Twongyirwe, Ronald; Sekajugo, John; Kabaseke, Clovis; Kagoro-Rugunda, Grace; Kervyn, Matthieu; Vranken, Liesbet
Smallholder farmers’ vulnerability to climate-related disasters in Sub-Saharan Africa is increasing, partly due to land-use changes and limited information about the adoption of farm-based Disaster Risk Reduction (DRR) measures. Classical agricultural extension workers are increasingly less trusted because they tend to transfer information not targeted to DRR, and rarely reach remote areas vulnerable to disasters. By extending the Theory of Planned Behavior (TPB), this study assesses whether Social Information Networks (SIN) can shape farmers’ perspectives regarding the adoption of DRR measures. Cross-sectional data were collected from 602 randomly selected households from Rwenzori and Ankole in Western Uganda, the sub-regions that are prone to landslides and floods. Results from the structural equation modeling demonstrate TPB as a strong framework to explain adoption behavior for DRR measures. Results show Perceived Behavioral Control (PBC) as a stronger driver of intentions than subjective norm and attitudes. Intentions to apply DRR measures are significantly associated with actual adoption. Farmers’ adoption behavior to control landslides and floods is directly correlated since the same location might simultaneously be at risk of such interacting disasters. Furthermore, SIN significantly predicts adoption intentions directly, and indirectly through PBC, subjective norm, and attitude. PBC and professional networks being the main drivers of adoption intentions suggests that the role of extension services cannot be substituted by informal social networks but the two should be complementary. Thus, the study shows the need to build the technical capacity of extension staff and informal networks in DRR measures to train and transfer information to farmers.
Exploring the genetic diversity of jackfruit (Artocarpus heterophyllus Lam.) grown in Uganda based on SSR markers
(Genetic Resources and Crop Evolution, 2020) Nakintu, Justine; Albrecht, Christian; Muller, Christina M.; Kagoro-Rugunda, Grace; Andama, Morgan; Olet, Eunice A.; Lejju, Julius B.; Gemeinholzer, Birgit
Artocarpus heterophyllus Lam. is an economically important tree crop that is widely cultivated inUganda for its fruit. Despite its economic importance, little is known about the genetic diversity of jackfruit in the country. This puts the crop’s genetic resource at risk as farmers selectively grow varieties based on market demand. The study analyzed the genetic diversity of A. heterophyllus trees from 12 districts belonging to three agro-ecological zones and three political regions of Uganda. Ten SSR loci were used to assess the genetic relationship among 200 trees, 197 from Uganda and 3 out-group individuals. All SSR loci were polymorphic with an average of 10.9 alleles per locus. STRUCTURE analysis proposed two genetic clusters: Cluster 1 was composed of samples from Eastern and neighboring Central districts, and Cluster 2 which constituted outgroups and samples from Western and neighboring Central districts. Results of STRUCTURE analysis were confirmed by PCoA. Mbarara District exhibited the highest genetic diversity (He = 0.79, I = 1.71), while Kamuli (He = 0.61, I = 1.08 and Pallisa (He = 0.59, I = 1.12) displayed the lowest genetic diversity despite high abundances of jackfruit trees. Molecular variation was higher within populations than among populations. Moderate and significant genetic differentiation was registered among geographical zones, while varietal differences displayed little insignificant genetic differentiation. Soft and white pulped varieties, considered inferior on the market, harbored private alleles which may be genetically valuable resources. Therefore, sustainable utilization and conservation efforts of the jackfruit genetic resource should consider preserving inferior varieties for future crop improvement.
Gis-Based Land Suitability Analysis for Ex-Situ Production of Threatened Citropsis articulata in Uganda
(Environment & Ecosystem Science (EES), 2021) Wangalwa, Rapheal; Apio Oleta, Eunice; Kagoro-Rugunda, Grace; Umba Tolo, Casim; Ogwang, Patrick. E.; Barasa, Bernard
Citropsis articulata (Spreng.) is a potent medicinal plant that is increasingly threatened by unsustainable harvesting and habitat destruction due to deforestation. This calls for enhancement of ex-situ conservation of C. articulata through offsite production. However, the success of offsite production of this species heavily rests on precisely assessing the suitability of the land for its production. In this study, an integrated GIS based multi-criteria evaluation approach was used to depict suitable areas for production of C. articulata based on key factors of; climate, soil and topography. Results revealed that only 13.04% (31495.77 km2) of Uganda’s land is very suitable to support natural production of C. articulata and is mainly situated in the western and central regions. Findings further revealed that 76.4% (24062.77 km2) of very suitable land area is situated outside protected areas, thus implying availability of potential sites for ex-situ and commercial production of C. articulata in the country. Findings also indicated that C. articulata has potential of thriving in well drained, moderately acidic soils and pleasantly warm regions endowed with moderately high precipitation and humidity. Since current stocks of C. articulata are mainly restricted to protected areas, cultivating this species will provide alternative sources of the plant harvest. This will help to relieve current pressures on the wild populations of C. articulata, thus providing a safety backup to the current in-situ conservation efforts.
Greed or Grievance? Linking Revenue Sharing Implementation to Unauthorised Resource Use and Conservation Support at Bwindi Impenetrable National Park
(East African Nature and Science Organization, 2024-08-06) Twinamatsiko, Medard; Gumisiriza , Bugabo, Stephen; Kagoro-Rugunda, Grace
Revenue sharing is considered a major incentive to promote Community Based Approaches to conservation of protected areas. The sharing of revenue from Protected Area resources is supported by conservationists to promote strong partnerships between protected area management and local communities to address unauthorised resource use for better conservation outcomes. This is premised on the ability of the shared revenue to translate into people’s livelihood improvement and minimize their dependency on resources from protected areas. However, empirical realities indicate that the practice of the Revenue Sharing policy barely addresses the initial objectives of human livelihood improvement to gain support for conservation. This study examined the Revenue Sharing Implementation, Data was collected from 715 respondents who included Local community members (including the unauthorised resource users), staff from conservation organisations in Bwindi and local council leaders. Data was collected using household survey questionnaires, key informant interviews and Focus Group Discussion (FGD). Results showed that most beneficiaries of the Revenue Sharing policy were random community households not the unauthorized resource users. The revenue sharing projects allocated to community members were majorly livelihood projects compared to common good projects. Projects included; livestock, passion fruit growing, poultry, provision of land and water projects. Unauthorised resource use was largely motivated by the need for bush meat, minor timber forest products especially firewood, collection of basketry materials and medicinal plants. Protected area managers ought to consider greater involvement of poachers in Revenue Sharing activities. Reducing unauthorized resource use requires systematic but also a combination of factors to mitigate the most driving forces that compel community members to engage in unauthorized forest resource use
Historicizing Natural Hazards and Human-Induced Landscape Transformation in a Tropical Mountainous Environment in Africa: Narratives from Elderly Citizens
(Land, 2025) Kanyiginya, Violet; Twongyirwe, Ronald; Mubiru, David; Caroline, Michellier; Mercy, Gloria Ashepet; Kagoro-Rugunda, Grace; Matthieu, Kervyn; Olivier, Dewitte
Studying natural hazards in the context of human-induced landscape transformation is complex, especially in regions with limited information. The narratives of the elderly can play a role in filling these knowledge gaps at the multi-decadal timescale. Here, we build upon a citizen-based elderly approach to understanding natural hazard patterns and landscape transformation in a tropical mountainous environment, the Kigezi Highlands (SW Uganda). We engaged 98 elderly citizens (>70 years old) living in eight small watersheds with different characteristics. Through interviews and focus group discussions, we reconstructed historical timelines and used participatory mapping to facilitate the interview process. We cross-checked the information of the elderly citizens with historical aerial photographs, archives, and field visits. Our results show that major land use/cover changes are associated with a high population increase over the last 80 years. We also evidence an increase in reported natural hazard events such as landslides and flash floods from the 1940s until the 1980s. Then, we notice a stabilization in the number of hazard events per decade, although the two most impacted decades (1980s and 2000s) stand out. Despite this new information, an increase in natural hazard frequency due to land use/cover change cannot yet be quantitatively validated, especially when the probable modulator effect of climate variability is considered. Nevertheless, the increase in the exposure of a vulnerable population to natural hazards is clear, and population growth together with poor landscape management practices are the key culprits that explain this evolution. This study demonstrates the added value of historical narratives in terms of understanding natural hazards in the context of environmental changes. This insight is essential for governments and non-governmental organizations for the development of policies and measures for disaster risk reduction that are grounded in the path dependence of local realities.
Occurrence of Citropsis articulata in Tropical Forests in Uganda: Implication for Ex Situ Conservation
(International Journal of Forestry Research, 2021) Wangalwa, Rapheal; Apio Olet, Eunice; Kagoro-Rugunda, Grace; Umba Tolo, Casim; Ogwang, Patrick E.; Barasa, Bernard
Citropsis articulata is a medicinal plant that is increasingly threatened by unsustainable methods of harvesting and habitat degradation. Owing to the fact that this plant species is highly utilized for herbal medicine and is currently restricted to a few forest reserves in Uganda, this has significant implications for ex situ conservation. ,erefore, the aim of this study was to assess how physiographical factors influence the occurrence and distribution of C. articulata in the three forest reserves in Uganda, namely, Budongo, Mabira, and Kibale National Park. ,e study was carried out in 15 compartmental sites in each of the three forests. In each compartmental site, 4 plots of 60m× 60m were systematically established, and within each plot, 4 subplots each of size 20m× 20m were randomly setup. A total of 240 subplots were assessed for occurrence of Citropsis articulata in each forest. ,eresults indicated a significant (p < 0.05) variation in the density of C. articulata with the highest recorded in Kibale National Park. Citropsis articulata generally occurred at moderate altitudinal landscapes (overall elevation = 1200.0 ± 20.73 m) with soils that are moderately acidic (overall pH= 5.7 ± 0.10), low in salinity (overall salinity = 84.0 ± 3.84 mg/l), and moderate levels of macro- and micronutrients. Citropsis articulata was generally associated with plant communities dominated by canopy tree species of genera such as Chryosphyllum, Celtis, Markhamia, Cynometra, Lasiodiscus, Trilepisium, Funtumia, and Diospyros, thus suggesting that C. articulata is a shade-tolerant species. Establishing the ecological requirements of this plant species among other things informs the potential for ex situ production of this plant. ,is will not only provide alternative sources of plant harvest but also go a long way in relieving the current harvest pressures exerted on the conserved wild populations of this plant species.
Traditional eye medicine use in microbial keratitis in Uganda: a mixed methods study [version 1; peer review: awaiting peer review]
(Wellcome open research, 2019) Arunga, Simon; Asiimwe, Allen; Apio Olet, Eunice; Kagoro-Rugunda, Grace; Ayebazibwe, Bosco; Onyango, John; Newton, Robert; Leck, Astrid; Macleod, David; Hu, Victor H.; Seeley, Janet; Burton, Matthew J.
Traditional eye medicine (TEM) is frequently used to treat microbial keratitis (MK) in many parts of Africa. Few reports have suggested that this is associated with a worse outcome. We undertook this large prospective study to determine how TEM use impacts presentation and outcome of MK and to explore reasons why people use TEM for treatment in Uganda. Methods: In a mixed method prospective cohort study, we enrolled patients presenting with MK at the two main eye units in Southern Uganda between December 2016 and March 2018 and collected information on history, TEM use, microbiology and 3-month outcomes. We conducted qualitative interviews with patients, carers traditional healers on reasons why people use TEM. Outcome measures included presenting vision and at 3-months, comparing TEM Users versus Non-Users. A thematic coding framework was deployed to explore reasons for use of TEM. Results: 188 out of 313 participants reported TEM use. TEM Users had a delayed presentation; median presenting time 18 days versus 14 days, p= 0.005; had larger ulcers 5.6 mm versus 4.3 mm p=0.0005; a worse presenting visual acuity median logarithm of the minimum angle of resolution (Log MAR) 1.5 versus 0.6, p=0.005; and, a worse visual acuity at 3 months median Log MAR 0.6 versus 0.2, p=0.010. In a multivariable logistic regression model, distance from the eye hospital and delayed presentation were associated with TEM use. Reasons for TEM use included lack of confidence in conventional medicine, health system breakdown, poverty, fear of the eye hospital, cultural belief in TEM, influence from traditional healers, personal circumstances and ignorance. : TEM users h Conclusion ad poorer clinical presentation and outcomes. Capacity building of the primary health centres to improve access to eye care and community behavioural change initiatives against TEM use should be encouraged.
