Resulta esencial calibrar las máquinas con el fin de lograr densidades de siembra y tasas de fertilización óptimas. Los errores en la calibración, incluso los más leves, pueden provocar grandes diferencias en el campo. Con la calibración se asegura que no se aplique demasiada semilla o fertilizante (con lo cual se ahorra dinero y se protege el medio ambiente), pero tampoco cantidades insuficientes, lo cual puede producir una disminución en el rendimiento.
This book is the re-titled third edition of the widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions,Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today.
Este volante muestra cinco etapas para la modernizacion sustentable de la agricultura.
La presentación es dirigida a productores y grupos de personas, que realizan actividades agrícolas, pecuarias, acuícolas y pesqueras en zonas rurales y periurbanas. El documento da recomendaciones para facilitar el acceso de los productores familiares al acompañamiento técnico y trata de modelos de extensión con mayor impacto en el desarrollo de la Agricultura Familiar.
PESA focaliza sus acciones en “Apoyar a las Unidades de Producción Familiar en localidades rurales de alta y muy alta marginación, para incrementar los niveles de producción y productividad de sus actividades agropecuarias, acuícolas y pesqueras…”.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
Small-scale farmers' experimental innovations have not generally been considered for on-farm research trials as those in the traditional sector have been perceived as recipients, rather than originators, of technical knowledge and sustainable and viable practices. Yet there is abundant evidence throughout the tropics that small-scale farmers are adaptive and experimental problem solvers, and experts at devising innovative survival strategies. While literature on the topic is rich with accounts from Africa, Asia and Latin America, there is a general dearth of examples from the Caribbean.
1. Many coastal communities depend on ecosystems for goods and services that contribute to human well-being. As long-standing interactions between people and nature are modified by global environmental change, dynamic and diversified livelihood strategies that enable seasonal adaptation will be critical for vulnerable coastal communities. However, the success of such strategies depends on a range of poorly understood influences. 2.
Farm input subsidies are often criticised on economic and ecological grounds. The promotion of natural resource management (NRM) technologies is widely seen as more sustainable to increase agricultural productivity and food security. Relatively little is known about how input subsidies affect farmers’ decisions to adopt NRM technologies. There are concerns of incompatibility, because NRM technologies are one strategy to reduce the use of external inputs in intensive production systems.
Research and the dissemination of evidence-based guidelines for best practice in crop production are fundamental for the protection of our crop yields against biotic and abiotic threats, and for meeting ambitious food production targets by 2050.
