La hidroponia o cultivo sin suelo es una técnica cuya importancia reside en su alta producción por metro cuadrado, gran eficiencia en el uso de agua y una multiplicidad de cultivos compatibles que brindan a los productores de zonas áridas y semiáridas una oportunidad interesante de producción (Birgi, 2015).
Este capitulo es parte de un libro del proyecto Específico “Procesos socio-técnicos de innovación en los territorios” del Instituto Nacional de Tecnología Agropecuaria (INTA) de Argentina.
Research, extension, and advisory services are some of the most knowledge-intensive elements of agricultural innovation systems. They are also among the heaviest users of information communication technologies (ICTs). This module introduces ICT developments in the wider innovation and knowledge systems as well as explores drivers of ICT use in research and extension
This chapter documents the learning process within the framework of innovation of soil fertility management practices that emerged from the implementation of Participatory Extension Approach (PEA) as part of service delivery reorientation within the Limpopo Department of Agriculture in South Africa.The chapter gives a narrative description of what transpired during the interaction between researchers, extension officers and farmers, the processes involved, the lessons and the conclusion.
This chapter outlines the role of a well-functioning agricultural innovation system in ensuring good use of public funds, and higher responsiveness to the needs of ‘innovation consumers’ through improved collaboration between public and private participants, including across national borders. A well-functioning agricultural innovation system is key to improving the economic, environmental and social performance of the food and agriculture sector.
Accordingly to the authors It is beyond the scope of this chapter to empirically explore the determinants of the commercialization of agriculture and its impact on poverty; so instead, they will present and discuss some empirical evidence on topics that remain hotly debated regarding commercialization and poverty. In Sect. 12.2, it is investigated how smallholder farmers in northern Vietnam have been affected by the recent food price volatility with respect to their income and consumption levels, while in Sect.
Por su complejidad, el cambio profundo que hoy requiere la formación docente se vincula con la capacidad de comprender y reconocer el surgimiento de los procesos “emergentes” que den paso a la innovación. Para poder identificar intervenciones con mayores oportunidades de tener incidencia en los procesos de formación, es necesario reconocer y comprender los procesos “emergentes” y su sostenibilidad cuando se pasa del nivel local al general (masificación).
Agricultural innovation invariably involves a whole range of partnerships, alliances and network-like arrangements that connect together knowledge users, knowledge producers and others involved in enabling innovation in the market, policy and civil society arenas. There is now a very large conceptual and empirical literature that reveals agricultural innovation not as process of invention driven by research, but as a process of making novel use of ideas (old and new) with the specific intention of adding social, economic and/or environmental value.
This chapter explores the interrelationships between economic change and environmental issues, by showing how aspiration, education, and migration are variously connected to a loss of agroecological knowledges for rural young people. It reviews a series of case studies from Vietnam, India, and China on the implications for rural youth of changed aspirations and ecological and economic stress. The economic and cultural pressures of globalization mean young people increasingly aspire for a life outside of agrarian- and natural resource-based livelihoods.
In the Amazon, slash and burn is the most common technique used by American-Indians, small farmers and even big ranches to transform forests into rural landscapes. The basis of food subsistence for diverse populations (rice, corn and bean), slash and burn is also a must for the plantation of cocoa, coffee, palms and pastures. The Amazonian rural landscape is currently dominated by pastures, occupying around 80 % of the deforested surface.
