Effect of Public Dept on Economic Growth in Kenya and the United States of America
(University of Nairobi, 2023) Wesonga, Emmanuel O.; Ondigo, Herick
The current study sought to assess the effect of public debt on the economic growth of Kenya and to compare this effect in the United States. This is a quantitative study based on secondary data that has been attained from the World Bank records. The figures used in this study are based on a period of 21 years, between 2000 and 2020. The study did not include data for 2021 and 2022 because of missing data points, especially for Kenya. The analysis is carried out at 95% confidence level, and as such, the critical value was 0.05. The research found no material causal relationship between public debt and economic growth (P value >0.05). Public debt also did not have any relationship with macroeconomic variables such as inflation (P. value >0.05). Macroeconomic variables and R&D spending were not significant in the association between economic development and national debt in Kenya (P value >0.05). There was no material association between public debt and R&D costs in Kenya. The results in the US also reveal that national debt has no substantial impact on economic growth. R&D spending, however, had a substantial positive relationship with economic growth in the US. Macroeconomic variables, including inflation, did not play a significant role in the association between economic growth and national debt in the US. The findings suggest that governments ought to carefully assess the economic condition of the nation...

Analysis of Drivers of Perceptions and Adoption of Integrated Maize Lethal Necrosis Disease Management Practices Across Selected Agro-ecological Zones in Kenya
(University of Nairobi, 2025) Kimani, Joseph G; Mburu, John I; Nzuma, Jonathan M; De-groote, Hugo; Gitonga, Zachary
Transboundary pests and diseases pose a major threat to cereal crops, including maize, which is a crucial staple for food security and income in Eastern and Southern Africa. These pests and diseases can significantly derail maize production, undermining efforts to improve food security and economic stability in the region. Maize Lethal Necrosis Disease (MLND)has emerged as one of the biotic stresses with huge impacts on maize yield and food security in Kenya and sub-Saharan Africa. Maize is highly vulnerable to MLND, which is caused by the combined effects of Maize chlorotic mottle virus and Sugarcane mosaic virus or related viruses. Since its outbreak in Kenya during 2011/2012, the disease has caused substantial yield losses. By 2018/2019, grain losses due to MLND reached USD 109 million, showing its economic impact. Control strategies include agronomic practices like crop rotation and tolerant varieties, mechanical methods such as uprooting and disposal of infected plants, and chemical controls targeting vectors like thrips and aphids. These form part of an integrated disease management approach for MLND. Despite extensive research on MLND pathology and control, little attention has been given to farmers’ perceptions, socioeconomic factors, and behavioral aspects. This study analyses farmers' awareness and perceptions on MLND. It also evaluates the adoption of integrated control practices across four agroecological zones (AEZs) in Kenya. Using a quantitative approach, the study used a two-stage stratified sampling method and conducted a structured survey through SurveyCTO with 398 smallholder maize farmers across the AEZs. The analysis includes descriptive statistics, Principal Component Analysis (PCA), multiple linear regression, multivariable Logistic regression, and a multivariate Probit model. Results show a moderate awareness level, with 41% of farmers recognizing MLND, though awareness varied by zone. Factors increasing awareness include education, farmer group membership, access to disease information and extension services. The PCA revealed three perception dimensions: awareness and symptoms, yield losses, and control practices. Regression showed education, media, and farm observation influenced awareness, while perceptions on yield losses related to education, experience, and extension access. Perceptions on control practices were affected by extension and disease information. Adoption of control methods included cultural (79%), mechanical (29%), chemical (15%), and tolerant varieties (7%). Older farmers with more livestock and positive perceptions preferred mechanical methods like rouging. Chemical control was linked to more livestock, perceived pesticide effectiveness, and specific zones. Adoption of cultural practices was influenced by age, intercropping, group participation, extension access, and positive views. These findings improve understanding of adoption and provide evidence-based advice for policymakers, extension services, and researchers to strengthen maize resilience against MLND. The study concludes awareness remains low, highlighting the need for targeted campaigns. It finds that mechanical and chemical methods complement each other, while cultural and chemical methods can substitute. For example, insecticides for thrips and aphids combined with mechanical removal reduce spread; alternatively, practices like intercropping, crop rotation, and MLND-tolerant varieties can replace chemicals. The findings highlight the crucial role of effective information dissemination, extension services, and farmer networks in influencing perceptions and fostering adoption. The study recommends strengthening farmer groups by using them as platforms for sharing information among extension officers and increasing access to reliable information. It also suggests creating demonstration plots for hands-on learning about the use of MLND control practices. Additionally, it highlights the importance of promoting resistant maize varieties through seed companies and agro-dealers, supported by policies that enhance pest and disease monitoring and improve communication from research institutions to farmers. Overall, these strategies highlight the importance of institutional backing, innovation, and social networks in managing MLND and protecting maize production. Future research could explore the impact of adopting these practices on crop yield.

Adoption of Apiculture for Community Resilience Under Changing Climate in Samburu Central Sub-county, Samburu County
(University of Nairobi, 2025) Karkar, Emily K; Nzioka, Muthama J; Mbau, Judith
Pastoralist communities in arid and semi-arid regions are facing increasing vulnerability due to climate change, which exacerbates challenges such as food insecurity and economic instability. This study investigated the adoption of apiculture as an adaptive strategy for enhancing community resilience under changing climatic conditions. The objectives were to: (i) assess community awareness of apiculture and its benefits; (ii) determine the distribution and abundance of bee forage plants in Samburu Central Sub-County (iii) evaluate habitat suitability for apiculture. Quantitative and quantitative data was collected from 189 households using structured questionnaires, interviews and focus group discussions. GIS-based techniques were applied to analyze land cover and bee forage distribution. Results indicated that while community awareness of the benefits of apiculture was relatively high, adoption remained moderate due to limited training, market access, and limited modern equipment. GIS mapping revealed that, 85000ha were suitable for apiculture during dry season and 102300h a during wet season. Croton spp, Olea Africana and Acacia spp were noted as common bee t forage plant species, indicating the strong ecological potential for apiculture expansion. Community awareness was found to be a crucial enabler for the adoption of apiculture. Inadequate understanding of the broader ecological and economic benefits of apiculture, beyond honey production, were found to constrain its adoption. Addressing this knowledge gap through targeted education and capacity-building initiatives are necessary to strengthen community adoption of apiculture and resilience. there is need to conserve and restore natural habitats for apiculture sustainability. This research contributes to the broader understanding of nature-based solutions in climate adaptation and rural development, especially in arid and semi-arid contexts.
