Landscape diagnostic survey data of rice production practices and yield of 2019 and 2020 from Nepal's Terai
No full textThe objective of the Landscape Diagnostic Survey (LDS) for rice is to bridge the existing data-gap around current production practices of rice, and also to help in evidence-based planning. The LDS is designed in a way that data is collected from randomly selected farmers spread uniformly within the Feed the Future (FtF) districs. Data has been collected from farmers largest rice plot for 2019, 2020 main (kharif) season . Survey questionnaire captures all production practices applied by farmers from land preparation to harvesting, including detailed sections on fertilizer use, weed control and irrigation application. Data is captured through electronically enabled Open Data Kit (ODK) tool on mobile phone or tablet.
The sample size for this survey in 2019 is 2917 households, and 2122 households for 2020. The inputs use were asked for largest rice grown plots as farms may have multiple plots and inputs use might be different in different plots
Dataset of the assessment of on-farm sustainability of vegetable farms in Benin Republic using the IDEA framework
No full textThe International Maize and Wheat Improvement Center (CIMMYT), the University of Abomey-Calavi, Benin and the World Vegetable Center conducted a survey in Benin in March 2023 to assess the on-farm sustainability of vegetable farms. A matrix of indicators was built around the three dimensions of sustainability (ecological, social and economic) using the “Indicateur de Durabilité des Exploitations Agricoles” (IDEA) framework. The dataset contains the following information: (1) general information on the farm owner; (2) presentation of the farm (production means, methods, and processes); (3) IDEA indicators scores in the three dimensions; ecological (components: ecological diversity, organization of spaces and agricultural practices), Social (components: production management, employment and local development, ethics and human development), and economic sustainability (components: viability, transmissibility, autonomy and efficiency)
Varietal turn-over and their effect on yield and food security – evidence from 20 years of household surveys in Kenya
No full textThe International Maize and Wheat Improvement Centre (CIMMYT), in collaboration with the Kenya Agriculture and Livestock Research Organization (KALRO) (previously the Kenya Agricultural Research Institute or KARI), conducted four nationally representative household surveys in the major maize growing areas during the last 30 years. All surveys used the same two-stage stratified design with maize production zones or agroecological zones (AEZs) as strata, census clusters or sublocations as primary sampling units, and maize-growing households as secondary sampling units. The first survey was conducted in 1992 and covered 79 clusters totaling 1397 farmers. This survey also defined the six AEZs, going from East to West, as the Coastal Lowlands, the Dry Mid-Altitude zone, the Dry Transitional zone, the Moist Transitional zone, the High Tropics, and the Moist-Mid Altitude zone. The second survey, conducted in 2002, covered 185 sublocations based on the 1999 census, with 1652 households. The third survey, of 2010, covered 120 sublocations with 1341 households while the fourth survey, of 2012, interviewed the same farmers with a replacement of 20% of randomly sampled households

Replication Data for: Impacto del cambio climático sobre la producción de maíz en México
No full textEl estudio examina el impacto del cambio climático en el cultivo de maíz en México para el período de los años 2050. Se identifica una tendencia generalizada hacia una disminución en los rendimientos debido al aumento de temperaturas y la reducción de precipitaciones, lo que podría amenazar la seguridad alimentaria y económica del país. Se utilizó un modelo de cultivos integrado en una suite de modelos para simular el crecimiento del maíz bajo diferentes condiciones climáticas y se aplicaron dos modelos globales de cambio climático para estimar los impactos en los rendimientos. Los resultados indican que la mayoría de los estados mexicanos sufrirán pérdidas en los rendimientos de maíz, con las mayores pérdidas pronosticadas bajo un escenario más seco. Se concluye que es crucial iniciar la planificación y actividades de adaptación para contrarrestar los efectos negativos del cambio climático en el cultivo de maíz en México, aprovechando las áreas con mejores condiciones y desarrollando prácticas agrícolas adecuadas. Se recomienda la integración de más modelos climáticos y tecnologías de adaptación en futuras investigaciones para una comprensión más completa de los efectos del cambio climático en la agricultura mexicana
Gender and Household Seed Security in Nepal
No full textThe study of women's involvement and responsibilities within seed systems in Nepal is scarce, despite the widely held belief that women possess extensive knowledge regarding seed selection and preservation, especially concerning maize and wheat, which are vital staple grains in remote mountain communities. Women play various crucial roles in maize and wheat farming, yet major decisions regarding crops management, such as variety selection, are predominantly made by men. Given the rising trend of male out-migration and the resulting feminization of agriculture, it is imperative to examine women's access to seeds and address the gender biases and limitations faced by women farmers
