    Challenges and Capacity Gaps in Smallholder Access to Digital Extension and Advisory Services in Kenya and Uganda
    (Frontiers of Agricultural Science and Engineering, 2022) Kansiime, Monica K.; Mugambi, Idah; Rware, Harrison; Alokit, Christine; Aliamo, Caroline; Zhang, Feng; Latzko, Jakob; Puyun, Yang; Karanja, Daniel; Dannie, Romney
    An assessment of the challenges and capacity gaps in smallholder access to digital extension and advisory services (EAS) was made by surveying 197 female and 239 male farmers in Kenya and Uganda. Non-digital extension approaches remain dominant but at least 78% of farmers accessed EAS from electronic sources dominated by radio. This is attributed to the fact that ownership of radios was more widespread than of other digital devices. Challenges that particularly limit the use of digital services included low digital literacy and prohibitive cost of internet and mobile devices. Female and elderly farmers were more likely to report these challenges than their counterparts. Logistic regression model results show that ownership of digital devices, participation in post-production activities, and access to extension were enablers of digital EAS use. Farmers mentioned gaps in obtaining information on crop pest/disease diagnosis and management, fertilizer application, pesticide safety and quality seed. Given the diversity in smallholder technological capabilities and information needs, the recommendations made include integration of digital communication within multimode advisory services that use different but linked communication channels, continued farmer digital innovation capacity enhancement, and participatory design approaches that deliver relevant and actionable information for inclusive scaling of extension activities.

    Land use practices and their implications on soil macro-fauna in Maasai Mara ecosystem
    (International Journal of Biodiversity and Conservation, 2012) Nyawira Muchane, Mary; Karanja, Daniel; Mwangi Wambugu, Geoffrey; Mwangi Mutahi, Joseph; Masiga, Clet Wandui; Mugoya, Charles; Muchai, Muchane
    The composition, abundance, diversity and species richness of soil macro-fauna communities were assessed in four major land use types present within protected and agricultural landscapes in Maasai Mara savannah ecosystem (MME), Kenya. The four land uses were: natural grassland; woodland, inside and outside protected area; maize mono-cropping and maize-bean intercropping systems in adjacent agricultural farms. Sampling of soil macro-fauna was carried out in November, 2009 (short rain), April 2010 (wet rainy season) and September 2010 (dry season). Hand sorting of soil taken from 25 × 25 × 30 cm monoliths was used to extract all soil macro fauna greater than 2 mm body length. A total of 3,658 individuals comprising of 128 species mainly belonging to Phylum Arthropoda distributed across 3 classes and 13 orders, and Phylum Annelida with one order were collected across the four different land use systems. Termites and ants, and to a lesser extent coleopteran and earthworms were the most abundant groups. Significant effects of land use on macro-fauna abundance and species richness in all cases (p<0.001) were observed. There were significant interaction between Season*Region*Land use (p<0.01), Region*Land use (p<0.05) and Region*Protection*Land use (p<0.02). Grassland and woodland had the highest density (1351.61 vs. 2852.47 individual m-2) of total macro-fauna, whilst the lowest density occurred in agricultural land (205.48 individual m-2). Agriculture altered macro-fauna communities by declining individuals from Order Coleoptera, Hymenoptera and isoptera by > 50% and eliminating some Orders/Species. Human related disturbances outside protected area network declined macro-fauna density in grassland and woodland in dry region (65.07 vs. 39.74%) but increased the density by 107 vs. 340% in wet region. The study highlights the important effect of agriculture on macro-fauna communities and the need for conservation alternatives in unprotected areas. This study supports conservation of biodiversity beyond protected area network.
