Le sud du Brésil qui possède un bon potentiel naturel en raison de son climat chaud et humide et de son relief favorable est voué principalement à l’élevage et aux cultures de soja, de riz et de maïs. Cette région, comme d’autres au Brésil, participe à la production de denrées agricoles pour le marché national et international. Elle est ainsi soumise à l’intensification des pratiques dont les impacts sur l’environnement sont notoires. L’étude concerne plus particulièrement le bassin versant de l’Ibicuí (46 800 km²), situé dans le sud-ouest de l’État de Rio Grande do Sul.
This study examines the role of public–private partnerships in international agricultural research. It is intended to provide policymakers, researchers, and business decisionmakers with an understanding of how such partnerships operate, how they promote the exchange of knowledge and technology, and how they contribute to poverty reduction.
Contract farming has gained in importance in many developing countries. Previous studies analysed effects of contracts on smallholder farmers’ welfare, yet mostlywithout considering that different types of contractual relationships exist. Here, we examine associations between contract farming and farm household income in the oilpalm sector of Ghana, explicitly differentiating between two types of contracts,namely simple marketing contracts and more comprehensive resource-providing contracts.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
Encouraging the adoption and diffusion of low-carbon agricultural technology innovation is an important measure to cope with climate change, reduce environmental pollution, and achieve sustainable agricultural development. Based on evolutionary game theory, this paper establishes a game model among agricultural enterprises, government, and farmers and analyzes the dynamic evolutionary process and evolutionary stable strategies of the major stakeholders.
New plant breeding technologies (NPBTs), including genetically modified and gene-edited crops, offer large potentials for sustainable agricultural development and food security while addressing shortcomings of the Green Revolution. This article reviews potentials, risks, and actually observed impacts of NPBTs. Regulatory aspects are also discussed. While the science is exciting and some clear benefits are already observable, overregulation and public misperceptions may obstruct efficient development and use of NPBTs.
En este artículo se procura identificar, describir y comparar la concepción de extensión rural que guía a nivel subjetivo las prácticas de extensión de técnicos que trabajan en diez diferentes países latinoamericanos, para luego comparar estas concepciones con los modelos y lineamientos de extensión propuestos por la bibliografía. Para esto, primero se describen distintas concepciones de extensión que han tenido importancia en América Latina a lo largo de la historia, luego se presenta la metodología de investigación utilizada, presentándose por último los resultados a los que arribó

Este artículo hace un análisis del perfil de la avicultura a pequeña escala realizada en el Estado de Espirito Santo, en Brasil, de los roles que posee en la agricultura familiar y de los que podría tener en una agricultura más sostenible.
This study aims to analyze the evolution of Brazilian agricultural production from the 1960s to now and summarizes some of the main findings from the historical view of Brazilian agriculture development. The arguments should rest here on how technical change and the national system of innovations have built an institutional environment to boost the agricultural sector, particularly in the past few decades. It is not easy to describe the path of Brazilian agricultural development , but organizing some important historical facts can help creating a full picture.
