This paper presents an overview of current opportunities and challenges facing efforts to increase the impact of rural and agricultural extension. The starting point for this analysis is in recognition that the days when agricultural extension was synonymous with the work of public sector agencies are over.
One of the most important challenges for the researchers in the 21st Century is related to global heating and climate change that can have as consequence the intensification of natural hazards. Another problem of changes in the Earth's climate is its impact in the agriculture production. In this scenario, application of statistical models as well as development of new methods become very important to aid in the analyses of climate from ground-based stations and outputs of forecasting models. Additionally, remote sensing images have been used to improve the monitoring of crop yields.
Face aux enjeux majeurs pour l’avenir de la sécurité alimentaire et de l’agriculture mondiale, le phénomène d’acquisition et de location de terres à grande échelle est un sujet fortement controversé qui mobilise activement les médias et l’opinion publique.
Le présent document est organisé en deux grandes parties. Une première partie dite « de synthèse » qui à partir de six études de cas d’investissement massif dans les terres en Afrique, en Asie et en Amérique latine, se propose de :
A lo largo de su historia, los servicios de Extensión y Asistencia Técnica en América Latina y el Caribe han sido un instrumento focalizado, mayormente, hacia la pequeña agricultura como una forma de mejorar las condiciones de vida en el entorno rural y llevar tecnologías (conocimientos) que sirvan no solo para aumentar la productividad, sino que devengan en un motor del desarrollo y un medio para alcanzar la seguridad alimentaria.
Este documento es una respuesta práctica a las necesidades que hemos observado a lo largo de los años por parte de los equipos técnicos y de actores sociales involucrados en los procesos de gestión del desarrollo rural en territorios. Es un material que asesora y que no debe ser aplicado como si fuera un formulario burocrático, de forma mecánica.
In this chapter the authors compute measures of total factor productivity (TFP) growth for developing countries and then contrast TFP growth with technological capital indexes. In developing these indexes, the authors incorporate schooling capital to yield two new indexes: Invention-Innovation Capital and Technology Mastery. They find that TFP performance is strongly related to technological capital and that technological capital is required for TFP and cost reduction growth.
The purpose of this article is to investigate effective reformism: strategies that innovation networks deploy to create changes in their environment in order to establish a more conducive context for the realization and durable embedding of their innovation projects. Using a case study approach, effective reformism efforts are analyzed in a technological innovation trajectory related to the implementation of a new poultry husbandry system and an organizational innovation trajectory concerning new ways of co-operation among individual farms to establish economies of scale.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
Participatory communication in development aims to facilitate the integration of interpersonal communication methods with conventional and new media channels, with the focus on encouraging all stakeholders to participate in the process. The growth of internet-based technologies has created new opportunities for facilitating this participation and enhancing the ability of resource-poor communities to access information and support and to share experiences and knowledge.
Analysis of the role of Global Value Chains (GVC) in accessing knowledge and enhancing learning and innovation. Global Value Chains, Innovation Systems, Governance, Foreign Direct Investment, Learning, Upgrading, Productivity. Three main conclusions emerge from the analytical framework and evidence presented in this paper.
