    Exploring Socio-Economic Characteristics on Adoption Intensity of Biochar Among Farming Households in Sub-Humid Regions of Western Kenya
    (UoEm, 2025-01-08) Kyalo, Annastacia Maitha; Mogaka, Hezron; Kirimi, Florence Kaumi; Kizito, Kwena; Ndirangu, Samuel Njiri; Onyari, Charles Nyambane; Muriithi, Lydia; Elvin, Otara Nyaboe; Mutungi, Scholastica Katava; Kiprotich, Shadrack; Njiru, Moses Muchangi; Kamau, Ezekiel Areri;
    Agriculture is a cornerstone of Kenya's economy, yet declining soil fertility and low adoption of sustainable agricultural technologies, such as biochar, have hindered productivity among smallholder farmers. Biochar is perceived to be a costeffective technology especially among resource constraint farming households. Despite many smallholder farmers acknowledging the importance of biochar as a soil amendment, most farmers face socio-economic barriers that hinder its adoption at scale. This study focused on how socio-economic factors influence adoption intensity of biochar, with a focus on the farming households in the sub-humid regions of Western Kenya. Employing a multistage stratified sampling procedure and Heckman selection model, the study reveals that awareness of biochar, access to credits, total land used in farming and education level positively and significantly influences adoption of biochar while total land owned in acres negatively and significantly influences adoption of biochar. Similarly, awareness of biochar, access to credits, and education level positively and significantly influences adoption intensity of biochar while terms of land ownership negatively and significantly influence adoption intensity of biochar. The study identifies awareness of biochar, education, credit access, and land ownership as key factors influencing its adoption by smallholder farmers. Promoting biochar as a soil amendment and carbon sequestration technique for farmers should be the main goal of the government, non-governmental organizations, and development organizations. Promoting the advantages of biochar for crop yields and soil fertility should be spearheaded by the Ministry of Agriculture's Extension Department. While development organizations offer financial assistance and training to promote adoption, policymakers should push farmer cooperatives to reduce the cost of biochar production and implementation

    Extension-Market Linkages on Banana Commercialisation Among Smallholder Farmers in Meru Region, Kenya
    (Journal of Agricultural Extension, 2022-01) Kirimi, Florence Kaumi; Onyari, Charles Nyambane; Njeru, Lucy Karega; Mogaka, Hezron Rasugu
    The study examined the effect of extension-market linkages on banana commercialisation among smallholder farmers in the Meru region, Kenya. The study sampled 400 farmers from a target population of 288,802 from the Meru region. The Tobit model was used to analyse the effect of extension-market linkages on banana commercialisation. The results revealed that sources of marketing information (Coef. -0.06) had a negative influence on farmers commercialising banana production. The result showed that the reliability of local extension service providers in enabling farmer’s access to market information (Coef. 0.04) had a positive influence on farmers commercialising banana production. The findings also showed that users of marketing information in the commercialisation banana business (Coef. 0.63) had a positive influence on farmers commercialising banana production. The study concludes that there was an association between extension marketing linkages and banana commercialization among smallholder farmers in Meru region, Kenya. Government should create and implement more policies that will favour and encourage farmers to commercialise bananas. This will help farmers increase their income.

    Factors Influencing Youth Farmers' Use of Soil and Water Conservation Technologies In Drylands of Machakos County,Kenya
    (UoEm, 2025-04-02) Mutungi, Scholastica Kavata; Mogaka, Hezron Rasugu; Kirimi, Florence Kaumi; Onyari, Charles Nyambane; Muriithi, Lydia; Otara, Elvin Nyaboe; Kiprotich, Shadrack; Njiru, Moses Muchangi; Kyalo, Annastacia Maitha; Kamau, Ezekiel Areri;
    Land degradation presents a serious threat to sustainable soil and water resources, primarily through erosion, declining soil fertility, and extreme weather events. Addressing these challenges involves selecting appropriate Soil and Water Conservation (SWC) technologies to mitigate soil quality decline and enhance agricultural productivity. Soil and water conservation technologies have been promoted across various regions, especially in dryland areas for several decades with mixed outcomes. Despite their positive impacts, the utilization intensity of these technologies at farm level remains low. Furthermore, there is limited information on use and use intensity of the technologies among youth farmers, who are key to driving agricultural transformation. This study investigates the socio-economic factors influencing the use and use intensity of SWC technologies among youth farmers. A cross-sectional survey was employed to gather data from 396 youth farmers selected through a multistage sampling procedure. The data were analyzed using descriptive statistics and the Cragg's Double Hurdle (DH) model. The findings revealed that among 12 independent variables included in regression analysis education level, farm income, and farming experience significantly determined the choice of using SWC technologies. Additionally, access to credit, marital status, education level, farming experience, land size, technical knowledge, training participation, farm income, and land ownership had significant effects on the intensity of use. These findings highlight the need for targeted interventions, such as strengthening credit access, enhancing technical training, and expanding educational opportunities to promote broader adoption and effective utilization of SWC technologies. Integrating these factors into policy and planning is essential to enhancing agricultural productivity, resilience and sustainability among youth farmers in dryland regions.
