Though extension services have long since proved their value to agricultural production and farmer prosperity, their record in sub-Saharan Africa has been mixed. To study the impact of such programs on farmers' learning about agricultural technologies, we implemented a quasi-randomized controlled trial and collected detailed panel data among Malawian farmers. Based on those findings, we develop a two-stage learning framework, in which farmers formulate yield expectations before deciding on how much effort to invest in learning about these processes.
We analyse the impact of intensity of tillage on wheat productivity and risk exposure using panel household-plot level data from Ethiopia. In order to control for selection bias, we estimate a flexible moment-based production function using an endogenous switching regression treatment effects model. We find that tillage has a complementary impact on productivity and risk exposure. As the intensity of tillage increases, productivity increases and farmers’ exposure to risk declines. Our results suggest that smallholder farmers use tillage as an ex-ante risk management strategy.
This article departs from the assumption that the challenge of putting the Farm to Fork Strategy (F2F) into action stems from the broader challenge of attaining cross-sectoral policy integration. Policy integration has been part of the EU's policy approach for a long time and has predominantly been achieved in the form of environmental policy integration (EPI). However, the scope of the F2F extends beyond EPI, as it includes the integration of climate-related concerns into sectoral policies, for instance.
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.
We present a model for research and development (R&D) investment in food innovations based on new plant engineering techniques (NPETs) and traditional hybridization methods. The framework combines uncertain and costly food innovation with consumers' willingness to pay (WTP) for the new food. The framework is applied with elicited WTP of French and US consumers for new improved apples. NPETs may be socially beneficial under full information and when the probability of success under NPETs is relatively high. Otherwise, the traditional hybridization is socially optimal.
This study established physicochemical and sensory characteristics of virgin olive oils (VOOs) and linked them to consumers’ liking using external preference mapping. We used five Tunisian and two foreign VOO varieties produced by two processing systems: discontinuous (sp) and continuous three-phase decanter (3p). The samples were analyzed and evaluated by a panel of 274 consumers. The external preference mapping revealed five VOO clusters with a consumer preference scores rating from 40% to 65%.
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.
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 documento explora las demandas tecnológicas y de extensión que los principales actores en el entorno institucional esperan que el INTA atienda, de cara al 2030.
Este estudio identifica factores que inciden en la adopción de tecnología e innovación productiva en la producción vitivinícola familiar ubicada en el Oasis Este de Mendoza. Se abordan realidades territoriales desde perspectivas cualitativas con productores entre 10 y 70 ha. Se indaga respecto de las visiones de nuevas tecnologías, como cambios organizacionales, de sistemas de conducción y de estrategias de diversificación para mejorar la actividad.
