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.
Mobile phones fit well into the lives of pastoralists in low-income countries. The technology is firmly integrated into most pastoralist communities, affecting and transforming several core activities. Most studies concerned with this relationship, however, have narrow regional and thematic foci. The complementarity or discrepancy between relevant research is unknown, and a critical assessment of the current state of research is lacking.
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%.
This book is the re-titled third edition of the widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions,Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today.
En Europe, depuis trois décennies, la prise en compte des enjeux environnementaux dans les politiques agricoles se traduit, en partie, par la conception de Mesures agrienvironnementales (MAE), visant à promouvoir le changement de pratiques. En France, ces mesures ont été mobilisées dans différents modèles de contrats avec les agriculteurs, passant d’un paradigme basé sur la subvention de la multifonctionnalité d’une exploitation agricole à une compensation des surcoûts liés à l’adoption de nouvelles pratiques plus vertueuses au niveau des parcelles.
Cet article aborde la mise en place d’un projet d’agroforesterie villageoise, pour la gestion intégrée des ressources naturelles, dans le hameau de Duale Mitterrand (52 ménages) situé sur le plateau des Batéké (République démocratique du Congo). Il repose sur un travail de terrain effectué entre février et mai 2012 dans le cadre du mémoire de fin d’études du master en sciences et gestion de l’environnement de l’Université Libre de Bruxelles (ULB).
Du fait de leur transversalité et de leur objet, l'évaluation des politiques de développement territorial ne peut pas s'appuyer sur les outils utilisés pour évaluer les politiques sectorielles. Les questions procédurales sont très largement dominantes, les dispositifs portant essentiellement sur la gouvernance et la coordination. Pour évaluer une démarche procédurale, il convient de préciser le référentiel d’évaluation à la fois en termes du quoi et du comment évaluer.
