Determinants and disparities in profitability along the potato value chain in South-Western Uganda
(IIARD – International Institute of Academic Research and Development, 2024) Nsiime, Patricia; Ndyetabula,Daniel; Jeckoniah, John
Potato farming, while meeting the demands of new food consumption patterns emanating from Uganda’s urbanization and dietary diversification due to globalization, has potential to provide a steady and reliable stream of income to its value chain actors. However, challenges and disparities such as unequal distribution of profits exist among the various value chain actors (VCAs) and these include seed multipliers, producers, aggregators, traders, and processors. The study aims at assessing determinants of profitability along the PVC in South- Western (SW) Uganda, by examining factors that influence revenues, operational costs and profits. A cross-sectional research design was adopted to collect data from a sample population of 375 respondents from the districts of Kabale, Kisoro, Rubanda and Rukiga using a semi-structured questionnaire. Using the International Business Machine (IBM) Statistical Package for Social Sciences (SPSS), primary data was analysed to determine descriptive statistics. In addition, the Logistic Regression Model (LRM) was used to determine the factors associated with PVC actors’ profitability. Study findings show that PVC actors’ revenues, operational costs and profit varied along the value chain with processors, aggregators and traders reporting the highest profits in relation to their operational costs while farmers reported the lowest. Notably, results indicated that sales turnover, lack of access to new knowledge, and failure to realise effective collaboration significantly influenced profitability along the chain. Thus, it is concluded that farmers do not benefit as much as the other actors in the PVC due to factors of power imbalances, market structures and, knowledge access. It is, therefore, recommended that the government of Uganda should formulate strategies to increase producers’ profitability. Such as the introduction and strengthening of farmers’ cooperatives, undertaking focused capacity-building programs, and making policy reforms

Participatory inclusiveness in the potato value chain in South-Western Uganda
(African Scientific Research and Innovation Council, 2025) Nsiime Patricia; Ndyetabula Daniel; Jeckoniah John; Ariho Alex
Smallholder farmers play a major role in the agricultural value chains (AVCs) of developing countries Uganda inclusive, and this has been of great concern to policy makers, development partners, research, and extension workers. The study underscores the evidence of participatory inclusiveness on the potato value chain (PVC) in South-Western (SW) Uganda. The study on which the paper is based adopted a cross- sectional mixed method research (MMR) design whereby both quantitative and qualitative data were collected using a Survey Research Questionnaire (SRQ) and a semi-structured interview (SSI) grid respectively. The population sample of 375 respondents to the SRQs and 79 participants to the SSIs was sourced from four Districts of Kisoro, Rubanda, Kabale and Rukiga in SW Uganda. The study was guided by the Relational Risk Theory (RRT) and the Theory of Incentives (TI) in examining participatory inclusiveness. The concept of participatory inclusiveness was studied along the independent variables (IVs) of collaboration, innovation, support opportunities, and combined participatory inclusiveness and dependent variables (DVs) of actor influencers (AIs) chain influencers (CIs) and environmental influencers (EIs). The Statistical Package for Social Sciences (SPSS) software was used to analyse quantitative data while thematic analysis helped to examine qualitative data. Generally, results from the descriptive statistical analysis and regression analysis through the Ordinary Least of Squares (OLS) model, showed that participatory inclusiveness was evident and affected by the PVC actors’ ability to access new knowledge, existing governance policies, and availability of extension services. The study recommends that individual actors in the PVC should have access to new and appropriate knowledge, chain leaders should enact and pursue good governance policies and the Government of Uganda (GoU) should empower and deploy its extension workers with the appropriate skills, competences, expertise, and necessary tools and equipment to effectively assist PVC actors, especially the small-holders. Development partners like Non- Governmental Organisations (NGOs) need to facilitate effective dissemination of information and influence policies and regulations relevant to PVC.

Gender differences in rice production participation among smallholder farmers in small-scale irrigation schemes in mbarali district, Tanzania
(ELSEVIER, 2024) Mwalyagile Neema; Jeckoniah, John N.; Salanga, Rymond J.
Smallholder farmers are crucial to agri-food production in sub-Saharan Africa. However, gender disparities in rice production participation persist in Tanzania. Existing research has yet to fully explore how demographic and socioeconomic factors influence gendered participation in rice production. This study assesses gender differences in rice production participation patterns among smallholder farmers and identify gender-related socio-economic and demographic factors influencing differences in participation within small-scale irrigation schemes in Mbarali District. Using cross-sectional approach, data were collected from 397 randomly selected farmers through structured questionnaire and analyzed with descriptive and inferential statistics, including ordered probit regression. The results revealed significant gender differences in rice production participation (p < 0.01). Male farmers had higher participation rates in activities such as land preparation, seedbed preparation, seedling management, irrigation, herbicide, fertilizer, pesticide application, harvesting, transporting, storage, and selling, while female farmers had higher participation rates in transplanting and weeding. The overall level of partici- pation was moderate, with 78 % of male farmers and 49 % of female farmers. However, larger proportion of females (43 %) were at a lower participation levels compared to only 1 % of male farmers, while 21 % of males and 8 % of females were at high participation levels. Factors like household size, farming management, hier- archical position within households, decision-making power, and the ability to access irrigation water positively influenced participation levels, while land size cultivated had a negative impact (p < 0.05). These were gender- related socio-economic and demographic factors that disadvantage female farmers’ participation (p < 0.05). While the age of the farmer and inadequacy of irrigation water significantly affected participation levels, farm- hired labour had positive influence, however, these factors were not gender-specific. The study concludes that gender differences in participation in rice production are influenced by demographic and socio-economic factors. To address these, the study recommends for interventions that reduce gender disparities by promoting equality in resource access, enhancing women’s decision-making power over resources and ability to access irrigation water, and ensure sufficient water in small-scale irrigation schemes. The government should create an enabling envi- ronment that supporting female farmers in small-scale irrigation schemes for broader gender equality in agri- culture and rural development.

Understanding gender power relations in irrigation resource access and decision-making in small-scale irrigation schemes in Mbarali District, Tanzania
(IIMT Journal of Management, 2024) Mwalyagile Neema; Jeckoniah John Nshimba; Salanga Raymond J.
Purpose – Resource access and decision-making power remain critical gender concerns. This paper examines gender power relations in irrigation resource access and decision-making among smallholder rice farmers in Mbarali District, Tanzania. Design/methodology/approach – The study utilized a cross-sectional research design with mixed-method approaches. Quantitative data from 397 smallholder rice farmers were collected through structured questionnaires and analyzed using descriptive and inferential statistics, including multiple linear regression models. Qualitative data from focus group discussions and key informant interviews were analyzed through thematic analysis. Findings – The study reveals that access to irrigation resources was mediated through multiple sources of power derived from the economic status of farmers, land ownership, marriage and social capital, shaping access differently for male and female farmers. Males dominated decision-making over land, labor, income and farming equipment, with exclusive irrigation water access rights. Multiple linear regression analysis showed that being male increased the decision-making power (coef. 5 0.890, p < 0.05). Factors like land size, scheme membership and joint farm management were positively associated with male decision-making power and marriage and joint rice selling enhanced female farmers (p < 0.01). Practical implications – The findings provide valuable insights for development practitioners and policymakers, highlighting the persistent gender inequalities in irrigation resources and decision-making. These insights inform practical and policy interventions to promote gender equality in resource access and decision-making. Originality/value – This paper contributes to the literature on how gender power relations shape irrigation resource access and decision-making, underscoring the need for gender-specific interventions to promote gender equality in resources.

Unveiling research gaps on male intimate partner violence (IPV) victims: a 25-Year bibliometric analysis
(ELSEVIER, 2026) Mdoe Christopher N.; Jeckoniah John N.; Ngowi Edwin E.
Male victims of intimate partner violence (IPV) remain comparatively underrepresented within the scholarly literature on IPV. While international frameworks and research agendas have primarily focused on violence against women, less scholarly attention has been directed toward male victimization. This study presents a bibliometric analysis of global research on male IPV victimization published between 2000 and 2025. Following the PRISMA 2020 protocol, 219 Scopus-indexed peer-reviewed articles met the inclusion criteria and were analyzed using Bibliometrix and VOSviewer. These tools were used to examine publication trends, co-authorship networks, citation patterns, and thematic research clusters. The results indicate a gradual increase in publications after 2015, with the most pronounced growth occurring between 2020 and 2025. >70% of studies were pub- lished within criminology, psychology, and social work, while public health, legal, and medical subject areas were comparatively less represented. Over 80% of publications originated from the United States, the United Kingdom, Canada, and Australia, with limited contributions from developing regions. Only 14.6% of the liter- ature consisted of review articles, indicating limited synthesis of existing evidence. Reported funding information also suggests a stronger emphasis on female-focused IPV research. Overall, the findings highlight disciplinary and geographic imbalances in scholarly attention to male IPV victimization and provide a structured evidence base to inform future empirical, theoretical, and bibliometric research.
