Yet, scientific evidence on the digital technologies utilised by smallholder food producers in SSA and the associated challenges still needs improvement. This review attempts to provide a thorough overview of the technologies currently being employed by smallholder farmers in SSA while also exploring the associated challenges and opportunities. Through a systematic literature search, 27 relevant studies were analysed to identify the region-wise current technologies, challenges, and opportunities. Results show that various digital technologies are employed, including digital extension services and digital marketing of agricultural products. These technologies improve access to information and markets and enhance productivity. However, challenges hinder widespread adoption. Limited internet connectivity, low digital literacy, inadequate infrastructure, and affordability issues impede progress. Gender disparities further limit the equitable distribution of digitalisation benefits. Despite these challenges, significant opportunities arise from adopting digital technologies. The potential advantages are market access, better decision-making capabilities, and increased income and livelihoods. Digitalisation offers transformative possibilities for smallholder farmers in SSA. Overcoming barriers such as limited connectivity and low digital literacy is crucial. By harnessing the opportunities digital technologies can offer, the livelihoods of smallholder farmers can be uplifted, contributing to the growth of agriculture in SSA.</p></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"18 ","pages":"Article 101286"},"PeriodicalIF":4.8,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666154324003235/pdfft?md5=19d4c398e5ba034885fe970b240bc251&pid=1-s2.0-S2666154324003235-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141605924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study employed mixed qualitative and quantitative approaches based on survey data drawn from 532 multistage randomly and proportionately sampled smallholder households, ten focus group discussions and two key informant interviews from the central region of Kenya. Multiple correspondence analysis and cluster analysis were used in exploring the organizational attributes of the CAIs. A multivariate probit model was employed to explore how organizational and household socio-economic characteristics influence participation patterns across the collective action typologies. The results revealed two typologies of collective action namely, efficiency and livelihood that were highly distinct in their level of formalization, membership composition, nature and scope of coordination, level of social capital, level of social networking and internal governance mechanisms. The households’ participation patterns across the efficiency and livelihood typology were differentially influenced by household demographics, farm and farming factors, assets, institutional and infrastructural factors. The findings suggest that a ‘one-size-fits-all’ collective action policy is inadequate and suggests a portfolio of context-specific collective action promotional policies. The policies would confer potential complementarities, synergistic and spillover effects in developing the CAIs to address multiple developmental objectives simultaneously.</p></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"18 ","pages":"Article 101288"},"PeriodicalIF":4.8,"publicationDate":"2024-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666154324003259/pdfft?md5=5be6eecdce3cc7b08e85a3b0f61c0721&pid=1-s2.0-S2666154324003259-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141636790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven genotypes were evaluated using a randomized complete block design with three replications. The results of the AMMI analysis of variance showed that tuber yield significantly (p ≤ 0.05) influenced genotype-environment interaction. This reveals that genotypes exhibit varying mean performance in tuber yield across different environments. The sum squared results showed that genotype (62.40 %) and environment (26.73 %) were the main contributors to tuber yield variation, while the genotype-environment interaction effect (10.87 %) contributed least to then tuber yield total variation. The AMMI, GGE biplot, and GSI analysis revealed Gudanie and Gorebella as superior genotypes in tuber yield, demonstrating high mean performance across tested environments. Thus, Gudanie and Gorebella have been chosen as the most broadly adaptable genotypes for production in all potato-growing agroecologies in the Dawuro zone.

A total of 648 male chicks were assigned to 9 diets: four Iranian wheat cultivars (Sardari, Azar2, Pishgam, Sirvan) with and without enzyme supplementation, plus a corn-based control (6 replicates/diet, 12 birds/pen). Diets were iso-caloric and iso-nitrogenous. Chicks were fed for 39 days. Corn-based diets generally led to higher feed intake (FI) throughout the study compared to most wheat-based diets. However, during the finishing period (25–39 days), broilers fed diets containing Sardari and Azar2 wheat achieved the best weight gain and feed conversion ratio (FCR) compared to those fed Sirvan cultivar. Most of the carcass traits were not affected by the experimental treatments. Blood glucose, aspartate aminotransferase (AST) activity, and high-density cholesterol (HDL) levels were all noticeably affected by the type of wheat in the diet. Jejunum length and cecum weight were greatest in birds fed different wheat cultivars, while the corn-based diet resulted in the shortest jejunum and cecum length. Adding enzymes to the Pishgam cultivar diet increased the length of the ileum. significant interactions between wheat cultivar and enzyme were observed for jejunal villi characteristics (length, thickness, number) and muscle layer thickness, Broilers fed the Sardari diet exhibited the deepest crypts and lowest villi length-to-crypt depth ratio. The study concluded that there is a significant effect of wheat cultivar diversity on broiler performance traits, blood chemistry, carcass characteristics, and gut health.

It also delves into the implications of this technology on factors such as land efficiency, environmental impact, and the biochemical composition of microalgae. In this manuscript, the potential solution to these challenges lies in the adoption of vertical semi-closed photobioreactors, which seamlessly integrate photobioreactor technology with principles of vertical farming. This perspective effectively underscores the pivotal role of photobioreactors in mitigating global climate change, as they contribute to processes such as carbon dioxide (CO₂) sequestration, conversion of greenhouse gases into increased biomass production, enhancement of air quality, and the modulation of climatic parameters. Furthermore, photobioreactors have the capacity to boost the production of bioactive compounds and biomass yields. For future considerations, we propose that the application of microalgae kinetics should be employed to gain a deeper understanding of microalgae production.

Water yam (<em>Dioscorea alata</em> L.) varieties are viable options, as they need less soil fertility and yield more than <em>D. rotundata</em>, but have a poor culinary performance. The aim of this study is to assess the agronomic and culinary performance of 15 improved water yam genotypes developed by the International Institute of Tropical Agriculture (IITA) compared to local cultivars. In 2022 and 2023, multilocal trials (4 sites) were performed in the yam-growing areas, and nine villages were selected for culinary evaluation. Linear mixed-effects models and generalized mixed-effects models showed significant differences (p &lt; 0.05) in location, year of experimentation, and certain evaluated agronomic parameters. The improved varieties had a strong likelihood of producing small tubers that could be used as seeds. The agronomic and culinary performance of local water yam accessions has been superior to that of improved varieties.
