Este estudio analizó la evolución de una red de innovación entre productores de hule natural durante tres periodos de observación (dos olas o tres años), y evaluó cómo los productores reaccionan a diferentes innovaciones en un momento dado. Las prácticas de innovación fueron agrupadas en tres actividades: control de plagas y enfermedades, establecimiento y manejo de plantaciones, y manejo de cosecha y poscosecha.
La extensión rural es un proceso de trabajo y acompañamiento con el productor orientado al desarrollo sostenible de sus capacidades. En México, se han adaptado una serie de modelos de extensión que van desde el norteamericano, implementado a principios de la década de 1980, hasta el modelo de hub o nodo de innovación (plataforma - módulo demostrativo - área de extensión), aplicado desde el 2010 en el marco del Programa MasAgro. El objetivo de este documento es analizar los diversos procesos de extensión en México.
Rural extension is a process of work and accompaniment with the producer aimed to sustainable development of their skills. In Mexico, a series of extension models have been adapted, that goes from the US, implemented in the early 1980’s, to the hub model or innovation node (platform - demonstration module - extension area) applied since 2010 under the MasAgro Program. The aim of this paper is to analyze the various processes of extension in Mexico.
The study first identified fully efficient farmers and then estimated technical efficiency of inefficient farmers, identifying their determinants by applying a Zero Inefficiency Stochastic Frontier Model (ZISFM) on a sample of 300 rice farmers from central-northern Thailand. Next, the study developed scenarios of potential production increase and resource conservation if technical inefficiency was eliminated. Results revealed that 13% of the sampled farmers were fully efficient, thereby justifying the use of our approach.
Agricultural mechanization in developing countries has taken at least two contested innovation pathways—the “incumbent trajectory” that promotes industrial agriculture, and an “alternative pathway” that supports small-scale mechanization for sustainable development of hillside farming systems.
The tank-based irrigated agricultural system in the Dry Zone of Sri Lanka is one of the oldest historically evolved agricultural systems in the world. The main component of the system consists of a connected series of man-made tanks constructed in shallow valleys to store, convey and utilize water for paddy cultivation. Up to 10,000 tanks originating from the heydays of ancient kingdoms are still integrated in the current agricultural landscape. During the last two millennia, this indigenous system has undergone many changes in technological, management and socio-cultural norms.
Smallholder rice farming is characterized by low returns and substantial environmental impact. Conversion to organic management and linking farmers to fair trade markets could offer an alternative. Engaging in certified cash-crop value chains could thereby provide an entry path to simultaneously reduce poverty and improve environmental sustainability. Based on comprehensive data from a representative sample of approximately 80 organic and 80 conventional farms in northern India, we compared yield and profitability of the main rotation crops over a period of five years.
Cette publication offre de nombreux exemples concrets détaillant différentes manières de réengager les jeunes dans le secteur agricole. Elle montre à quel point des programmes éducationnels sur mesure peuvent offrir aux jeunes les compétences et la perspicacité nécessaires pour se lancer en agriculture et adopter des méthodes de production respectueuses de l’environnement. Beaucoup des approches ou des initiatives décrites dans cette publication sont issues des jeunes eux-mêmes.
Although Colombia has the potential to be a cocoa producer for fine flavor and high value markets, it is not greatly recognized as such. In spite of the government’s interest to position the country as a major specialty cocoa producer, no strategic actions have been taken to develop and strengthen this aspect of the value chain.
El objetivo de esta investigación fue identificar la oferta y demanda tecnológica para plantear alternativas en la innovación de la cadena agroalimentaria de maíz en el estado de Hidalgo, México. Se realizaron las siguientes etapas: 1) caracterización de la cadena; 2) identificación de los factores críticos; 3) distinción de demandas tecnológicas de conocimiento y política; 4) reconocimiento de la oferta tecnológica y 5) cuantificación de proyectos de investigación y política pública.
