This article rebuts the argument that shortcomings in Bt cotton studies and divergence between yield gains and extent of adoption of Bt hybrids make it impossible to conclusively say anything about the impact of genetically modified seeds. Further, it points out that there have been numerous studies that have controlled for selection and cultivation bias, and concluded that Bt cotton has had statistically significant positive yield effects.
Precision farming enables agricultural management decisions to be tailored spatially and temporally. Site-specific sensing, sampling, and managing allow farmers to treat a field as a heterogeneous entity. Through targeted use of in- puts, precision farming reduces waste, thereby cutting both private variable costs and the environmental costs such as those of agrichemical residuals. At present, large farms in developed countries are the main adopters of pre- cision farming.

ABSTRACT. In the last decades, a growing scholarship has outlined the crucial role of social networks as a source of resilience. However, with regard to the Global South, the role of social networks for the resilience of rural communities remains an under- researched and underconceptualized issue, because research remains scattered between different strands and has rarely been integrated from a resilience perspective.
On observe depuis les années 2000 la volonté des acteurs de la sécurité alimentaire de rapprocher résilience et sécurité alimentaire. Ce rapprochement n’apparaît cependant pas si évident au vu de la diversité d’éléments de langages utilisés pour les associer. Cet article vise donc à faire un état des lieux de l’association de ces notions, voire de leur intégration mutuelle. L’application de la résilience à la sécurité alimentaire met-elle en avant les mêmes dimensions que lorsqu’elle est appliquée aux systèmes socioécologiques ? Y aurait-il ainsi plusieurs concepts de résilience ?
L’agriculture mondiale est confrontée à de nombreux défis en termes de souveraineté alimentaire. Il s’agit d’abord d’assurer un accès équitable à la nourriture et aux produits agricoles de première nécessité pour une population mondiale croissante. Il s’agit ensuite d’inclure la production agricole dans une perspective plus générale de lutte contre la pauvreté, l’inégalité et la malnutrition dans le monde. Il s’agit enfin de contribuer à une gestion plus durable des ressources naturelles et agricoles et de la biodiversité.
L’article analyse en quoi et comment la recherche peut être un vecteur de renforcement des dynamiques collectives des territoires par la méthode participative ImpresS (Impact des recherches au Sud). Celle-ci qualifie la façon dont la recherche accompagne les processus d’innovation et y contribue, et la façon dont elle renforce les actions collectives par la création de nouveaux espaces de dialogue et d’échanges entre les chercheurs et les parties prenantes d’un projet d’indication géographique (IG).
The national assessment of the agricultural innovation system (AIS) in Malawi was conducted using a framework of four types of analyses: functional, structural, capacity and enabling environment analysis. The approach included five case studies that addressed three methods including the use of indigenous methods for fall armyworm (FAW) control in Farmer Field Schools (FFS), livestock transfer programs, and a horticulture marketing innovation platform in Mzimba, Ntchisi, Balaka, and Thyolo districts.
To keep yield advances, farmers in Mato Grosso (MT) have been adopting several technological innovations. Therefore, agricultural production systems in MT have become complex and dynamic since farmers have to consider the increase of decision variables when planning and implementing their farming practices. These variables are widely spread across many distinct topics, bringing them together and summarizing information from diverse fields of research has become a difficult task in farmers’ decision-making process.
The adoption of innovations and Precision Agriculture Technologies (PAT) is fundamental for establishing the patterns of agricultural production. However, the dynamics of adoption of PAT by farmers differs by regions. Although there is large number of related researches, there are considerable gaps in the literature: studies on adoption of PAT can be systematically reviewed and integrated in a conceptual model of technology adoption by rural producers, which still lacking in the literature.
