Agricultural mechanization in Honduras: characterization, challenges, and opportunities for maize, beans, and coffee production systems.
No full textCIMMYT and Universidad Zamorano carried out a study across five departments of Honduras (Lempira, Copán, Intibucá, Olancho, and El Paraíso) to characterize farmers’ use of tools and machinery in maize, bean, and coffee systems, and to identify key challenges and opportunities for mechanization. In total, 112 structured surveys of farmers were conducted.
This dataset includes the survey results, providing information about household and farm characteristics, crops grown and area per crop, plot location and topography (hillsides, plains, or mixed terrain), and the tools and machinery used in each operation, such as land preparation, planting, weeding, harvesting, and post-harvest. It also includes information about access to mechanization services, reasons for lacking machinery, perceived benefits of using machinery, and cropping cycle stages that need mechanization, among other details. This can help guide the design of mechanization pathways suited to smallholder conditions in Honduras.</p
Estimación del gasto energético durante el uso de herramientas manuales para el desgrane de maíz
No full textLos datos presentados provienen de una evaluación agro-técnica de herramientas para el desgrane manual de maíz. En el estudio participaron tres operadores, quienes fueron previamente informados sobre los procedimientos de toma de datos. Se evaluaron cuatro herramientas en términos de capacidad de trabajo y calidad del desgrane, considerando, entre otros aspectos, el porcentaje de daño mecánico ocasionado al grano.
Durante las actividades de desgrane se monitoreó el ritmo cardíaco de cada operador, con el fin de estimar el gasto energético asociado al uso de cada herramienta. Adicionalmente, la evaluación se complementó con criterios de percepción del usuario, mediante preguntas relacionadas con el nivel de cansancio, la rapidez del trabajo y la facilidad de operación de las herramientas.</p
Evaluating sustainable cropping systems: A comparative study of agricultural practices in Central Malawi
No full textThis database contains grain, biomasss and nutritional yield data from on-farm trials in Kasungu, Mchinji, and Lilongwe districts of central Malawi, conducted over three cropping seasons (2014–15 to 2016-17). The trials tested sustainable and resilient cropping systems, including Conservation Agriculture (CA) with minimum tillage, glyphosate herbicide, and maize-legume rotations, compared to conventional ridge-and-furrow sole maize (True farmer practice). The experiments were conducted on 24 farms, with each farm serving as one replicate. Data collected included grain yield, biomass, protein, and energy yields, providing insights into system performance and sustainability
Wheat Blast Data for four CIMMYT wheat nurseries during the 2024 cropping cycle
No full textWheat head blast index (%) data for four CIMMYT nurseries (15HLBSN, 15HZAN, 41SAWSN, and 56IBWSN) is presented. Field trials took place in Quirusillas and Okinawa (Bolivia) and Jashore (Bangladesh) during the 2024 cycles. Two sowings were made in each location/cycle except for Quirusillas where only one sowing was made
Replication Data for: Changing the Narrative: Resilience of Women in STEM in sub-Saharan Africa and Institutional Innovations to Advance Equity
No full textThis study examines the challenges and strategies of women postgraduate students in science, technology, engineering, and mathematics (STEM) in African institutions.
Using a mixed-methods approach, it combines data from an online survey conducted in 2020 with 163 women STEM doctoral alumni from 40 universities in sub-Saharan Africa, with qualitative data from seven focus groups conducted in 2019/2020 with 39 master's and doctoral students in STEM at four universities in East and West Africa (Kenya, Rwanda, and Senegal).
The study reveals common challenges such as financial stress, gender stereotypes, and harassment, and highlights the resilience and success strategies of these women, contributing to identifying best practices for promoting inclusion in STEM.</p
2025 CIMMYT Maize Eastern Africa Product Announcement
No full textNew and improved maize hybrids, developed by the CIMMYT Global Maize Program, are available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across eastern Africa and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in the 2024 Stage 5 trials, CIMMYT advanced a total of seven new elite maize hybrids in eastern Africa in 2025. Phenotypic data collected in Stage 4 and Stage 5 trials for the selected hybrids as well as information about the trial sites are provided in this dataset. These trials were conducted through a network of partners, including NARES and private seed companies, in eastern Africa under various management and environmental conditions
Replication Data for: Management of maize‑legume conservation agriculture systems rather than varietal choice fosters human nutrition in Malawi
No full textThis study evaluated the impact of cropping systems (conventional ploughing, no-tillage, and conservation agriculture) and maize varieties on agricultural productivity and nutritional outcomes across multiple districts in Malawi. Results indicated that conservation agriculture significantly enhanced crop yields and nutritional outputs compared to conventional methods, suggesting its potential to improve food security and climate resilience for smallholder farmers
Soil properties predicted from mid-infrared spectral (MIRS) analysis of soil samples collected in 2023 (second year) before and/or after establishing on-farm trials on yield response to lime rates in Ethiopia
No full text Selected soil properties were predicted from 232 topsoil samples subjected to spectral analysis (MIRS). A subset of samples were also subjected to wet chemistry analysis, and results were used to calibrate a machine-learning algorithm developed by the International Centre for Research in Agroforestry (ICRAF) in Kenya. Coordinates were truncated to protect farmer's privacy.
Unless specified, all properties were predicted. This dataset can be linked with yield data (coming soon) and previous soil analysis data (https://hdl.handle.net/11529/10549136) through the unique farm identifer "fid".

Household Data set on Patterns of livelihood diversification in farming systems of the Eastern Gangetic Plains
No full textThe Eastern Gangetic Plains (EGP) region, characterized by smallholder-dominated farming, is experiencing rapid socio-economic and environmental changes. To enhance resilience, income stability, and food security, smallholders are increasingly diversifying their livelihoods away from traditional agriculture. However, the patterns and drivers of this diversification remain poorly understood.
This study, utilizing data from the Rupantar project, aims to elucidate these patterns, identify key drivers, and assess the impacts on productivity, profitability, nutrition, and inclusion. A mixed-methods approach was employed, including a baseline survey of 1,400 households across India, Nepal, and Bangladesh and analysis using the Simpson’s Index of Diversity (SID). Fractional regression models revealed moderate diversification levels across the EGP with significant geographical and contextual variability. Key drivers included access to resources, gender, education, market access, and institutional support, with differences observed across countries and diversification types. Factors such as non-ownership of irrigation pumps, female household headship, and engagement in off-farm activities were significant predictors of higher diversification.
The study found that diversification can enhance income security, nutritional outcomes, and environmental sustainability, although impacts vary by diversification type. This highlights the need for targeted policies to support effective diversification strategies. By providing insights into the specific drivers and outcomes of diversification, the study informs policymakers and practitioners seeking to bolster rural livelihoods in the EGP, emphasizing the importance of gender, resource access, and institutional support.</p
