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.
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…”.
La extensión es el proceso de intervención de carácter educativo y transformador, cuyo objetivo es el desarrollo económico y social de las familias rurales, a través de servicios de asistencia técnica, intercambio de tecnología, desarrollo de capacidades y capacitación. Este documento muestra como lograr estos servicios.
This article presents the results of a study conducted in Northeast Thailand on wild food plant gathering in anthropogenic areas and the implications for vulnerable households. A sub-sample of 40 farming households was visited every month to conduct seven-day recalls over a 12-month period on wild food plant acquisition events. Results show that these plants are an essential part of the diet, constituting a "rural safety net" particularly for vulnerable households.
This paper takes the viewpoint of a social scientist and looks at agricultural scientists' pathways for science impact. Awareness of these pathways is increasingly becoming part and parcel of the professionalism of the agricultural scientist, now that the pressure is on to mobilize smallholders and their productive resources for (global) food security and for reducing persistent rural poverty. Significant new thinking about pathways is emerging and it is useful to present some of this, even if it is not cut-and-dried.
Little is known about effective ways to operationalize agricultural innovation processes. The authors of this article use the MasAgro program in Mexico (which aims to increase maize and wheat productivity, profitability and sustainability), and the experiences of middle level ‘hub managers’, to understand how innovation processes occur in heterogeneous and changing contexts. Their research shows how a program, that initially had a relatively narrow technology focus, evolved towards an innovation system approach.
Climate variability and change threaten and impact negatively on biodiversity, agricultural sustainability, ecosystems, and economic and social structures – factors that are all vital for human resilience and wellbeing. To cope with these challenges, embracing sustainability in food production is therefore essential. Practising sustainable agriculture is one way of ensuring sustainability in pro-poor farming communities in low-income countries.
Many indigenous vegetables are generally underutilized across different cultures, but they remain alternatives to exotic vegetables that often are expensive. This study investigated effects of participation in indigenous vegetable production on livelihood of farmers. Multistaged sampling was used to collect data from 222 vegetable farmers sampled from using a semi-structured questionnaire. Principal component analysis and endogenous switching regression (ESR) were employed for analysis
