This article adds to the literature about the impact of social networks on the adoption of modern seed technologies among smallholder farmers in developing countries. The analysis centers on the adoption of hybrid wheat and hybrid pearl millet in India. In the local context, both crops are cultivated mainly on a subsistence basis, and they provide examples of hybrid technologies at very different diffusion stages: while hybrid wheat was commercialized in India only in 2001, hybrid pearl millet was launched in 1965.
The role of genetically modified (GM) crops for food security is the subject of public controversy. GM crops could contribute to food production increases and higher food availability. There may also be impacts on food quality and nutrient composition. Finally, growing GM crops may influence farmers’ income and thus their economic access to food. Smallholder farmers make up a large proportion of the undernourished people worldwide. Our study focuses on this latter aspect and provides the first ex post analysis of food security impacts of GM crops at the micro level.
Productivity growth in smallholder agriculture is an important driver of rural economic development and poverty reduction. However, smallholder farmers often have limited access to information, which can be a serious constraint for increasing productivity. One potential mechanism to reduce information constraints is the public agricultural extension service, but its effectiveness has often been low in the past.
While several studies have shown that genetically modified Bt cotton can benefit smallholder farmers economically, the sustainability of these effects is still unclear and debated controversially between biotechnology proponents and critics. We use unique panel data of 533 cotton farmers, collected in India between 2002 and 2008, to analyze Bt impacts on cotton yield, profit, and household living standards. Results from fixed effects models show that the adoption of Bt cotton is associated with a net yield gain of 24% and a profit increase of 50%.
Iron deficiency is a widespread nutritional problem in developing countries, causing impaired physical activity and cognitive development, as well as maternal mortality. Although food fortification and supplementation programmes have been effective in some countries, their overall success remains limited. Biofortification, that is, breeding crops for higher micronutrient content, is a relatively new approach. We propose a methodology for ex-ante impact assessment of iron biofortification, which builds on disability-adjusted life years (DALYs) and a large household data set.
The Guidance Note on Operationalization provides a brief recap of the conceptual underpinnings and principles of the TAP Common Framework as well as a more detailed guide to operationalization of the proposed dual pathways approach. It offers also a strategy for monitoring and evaluation as well as a toolbox of select tools that may be useful at the different stages of the CD for AIS cycle.
The Conceptual Background provides an in-depth analysis of the conceptual underpinnings and principles of the TAP Common Framework. It is also available in French and Spanish.
This report summarizes the international symposium organized on 21 June 2016 by the Tropical Agricultural Platform (TAP) to discuss capacity development for food security and nutrition in Agricultural Innovation Systems (AIS). In addition, the symposium aimed to present the findings of the e-conference on "Innovation systems for food security and nutrition: understanding the capacities needed" that took place between 18 April and 13 May 2016.
Le document de synthèse fournit une synthèse des concepts et des principes du cadre commun développé dans le cadre de la Plate-forme pour l'agriculture tropicale (TAP). L'objectif du Cadre Commun de la TAP est de promouvoir une meilleure cohérence et un impact plus fort du renforcement des capacités (RC) en soutien aux systèmes d'innovation agricole (AIS) sous les tropiques. Développé en 2015 à travers un processus hautement participatif, il a été convenu que le Cadre devrait fournir des bases conceptuelles et des indications pratiques.
La «Note d'Orientation sur l'Opérationnalisation» récapitule brièvement les fondements conceptuels et les principes du Cadre commun de travail pour le renforcement des capacités des systèmes d'innovation agricole et fournit également un guide détaillé de l'opérationnalisation de l'approche à Double Entrée du renforcement des capacités (RC) pour les systèmes d'innovation agricole (SIA). Le document offre aussi une stratégie de suivi et d'évaluation ainsi qu'une Boîte à Outils d'outils sélectionnés qui peuvent être utiles aux différentes étapes du RC pour les SIA.
