“…Por su importancia en México, la semilla de maíz está en el centro de debates y discusiones de política sobre qué tipos de semillas y sistema de producción asociados es el mejor (Turrent et al 2017), cuáles son niveles adecuados de participación de los materiales de mejoramiento público y de empresas nacionales y multinacionales (Espinosa et al, 2014;Luna et al, 2012). La intención de presentar y analizar nuevos datos y evidencia sobre la estructura, es contribuir a evaluar y mejorar la gestión del consorcio y de otras políticas y a enriquecer el debate público sobre las opciones de semillas para mejorar la producción de maíz en México.…”

Introducción. El rápido crecimiento de la inversión privada en el sector de semillas de maíz plantea desafíos para los organismos públicos y las empresas más pequeñas que tienen cada vez menor acceso a tecnologías y mercados. El Consorcio Internacional de Mejoramiento de Maíz (IMIC-LA), creado en México en 2011, busca aumentar el tamaño y la competitividad del sector semillero mediante el acceso a germoplasma y herramientas de mejoramiento. Sin embargo, no hay datos y medidas básicas recientes de la estructura que permitan evaluar esta y otras iniciativas del sector. Objetivo. Actualizar y analizar los indicadores de ventas totales, participación en ventas por categorías de empresas y tipos de variedades de semilla, y cobertura con semillas mejoradas, en México. Materiales y métodos. Se utilizaron datos de ventas de semillas de maíz de entrevistas y encuestas con empresas semilleras y estadísticas oficiales de producción de semillas del Servicio Nacional de Inspección y Certificación de Semillas (SNICS) del año 2011 al año 2016. Resultados. Los resultados mostraron un sector semillero más grande y competitivo después de veinticinco años de apertura, especialmente en los años más recientes en los que se destaca el rápido aumento del volumen y la participación de las ventas del subsector de empresas nacionales. Conclusión. La amplia participación de las empresas como miembros del consorcio y el desarrollo y comercialización de nuevas variedades, sugieren un impacto positivo y un papel en el crecimiento y competitividad de las empresas semilleras nacionales.

“…Intercropping and rotations with beans, fruit trees and several other crops relevant for the diet of local people or for the markets (e.g. Turrent-Fernández et al 2017;Ruiz-Mendoza et al 2012) can represent options to improve the food security of these types of farm households.…”

Food security and agriculture in the Western Highlands of Guatemala

Food security is a major challenge in Guatemala, one of the poorest countries in the world. Food insecurity is concentrated in the Western Highlands of Guatemala (WHG) where indigenous communities have been the main victims of social, political and economic marginalization. In this study we characterize the diversity of farming households in the WHG, identify the main sources of food for different types of farm households and assess their food security status through a simple, yet robust, potential food availability indicator. Based on a large and rich dataset of nearly 5000 farm households, our results show the diversity of farming systems in the region, dominated by maize and coffee production, as well as the large differences in their potential food availability. In our model, 52% of farm households in the WHG did not have the means to attain sufficient energy from their agricultural activities. In general, diversified maize-based, coffee-based and specialized coffee farm households had larger proportions of potentially food secure households with 60%, 83% and 74% food secure households, respectively. This contrasted with farm households specialized in maize production and resource-constrained households where there were a greater proportion of households were food insecure. The analytical framework presented here, combining a typology of farm households and their livelihoods with the analysis of their food security status, provides a useful approach for better targeting development interventions towards combating hunger, poverty and malnutrition.

“…Maize residues and tree clippings are placed in tree rows to catch run-off and gradually create terraces. Some studies have concluded that conservation agriculture and agroforestry are not compatible (Turrent Fernández et al, 2017;Ndoli et al, 2018), while other authors see them as complementary (Sims et al, 2009;Bayala et al, 2011;Reyes Jaramillo, 2016). Their compatibility probably depends on local agro-ecological and socio-economic conditions and how both practices are implemented and adapted to those conditions.…”

Maize (Zea mays L.), the staple crop of Mexico, is often produced by smallholder farmers on sloping terrains. Historically, little agronomic research has been performed under the conditions of these farmers to support them in the sustainable intensification of their production systems. We set up trials at two locations in the state of Oaxaca to evaluate conservation agriculture and agroforestry in collaboration with local farmers. Crop diversification through crop rotations, multicropping, relay cropping or agroforestry increased system yields the most, by up to 1.4 t ha−1 in Teopoxco and 1.7 t ha−1 in Tamazulapam. Increased input use through increased fertilization or liming did not increase profitability enough to justify their use. Zero tillage and residue retention increased yields and reduced production costs. Conservation agriculture with agroforestry was a high-yielding, profitable system that also reduced farmers' risk by providing several harvests per year. The most profitable combinations of agroforestry and conservation agriculture could produce up to $4,854 USD ha−1 in Teopoxco and $2,143 USD ha−1 in Tamazulapam, while the control treatments in the same sites and years produced $175 USD ha−1 and $92 USD ha−1 respectively. In several years the main crop failed, while the trees were able to produce due to their different growing season compared to maize. Through adaptive investigation under farmers' conditions, sustainable intensification of traditional production system is possible with low-cost changes that are locally adapted and within farmers' possibilities.
