Cet article présente une enquête menée dans le nord-ouest du Nicaragua, qui vise à comprendre comment les flux d’argent et d’aliments générés par les activités diversifiées et multilocalisées des familles agricoles interviennent dans l’accès aux aliments et dans la perception de la sécurité alimentaire. Dans la région d’étude, l’agriculture familiale est caractérisée par des conditions agro-écologiques difficiles et repose sur la production vivrière et l’élevage bovin.
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.
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.
This brochure presents FAO ’s work on agricultural innovation. FAO advocates a shift from interventions focusing on single components of agricultural innovation towards a system-approach aimed at strengthening institutions and stakeholders’ networks that better respond to the needs of smallholder farmers.
In the past 50 years, the application of synthetic nitrogen (N) fertilizer to farmland resulted in a dramatic increase in crop yields but with considerable negative impacts on the environment. New solutions are therefore needed to simultaneously increase yields while maintaining, or preferably decreasing, applied N to maximize the nitrogen use efficiency (NUE) of crops. In this review, we outline the definition of NUE, the selection and development of NUE crops, and the factors that interact with NUE.
Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physical properties have been predicted by reflectance spectroscopy successfully on subtropical and temperate soils, whereas soils from tropical agro-forest regions have received less attention, especially those from tropical rainforests. A spectral characterization provides a proficient pathway for soil characterization.
This article extends social science research on big data and data platforms through a focus on agriculture, which has received relatively less attention than other sectors like health. In this paper, I use a responsible innovation framework to move attention to the social and ethical dimensions of big data “upstream,” to decision-making in the very selection of agricultural data and the building of its infrastructures.
As the world gets hotter and rainfall more erratic, the type and availability of ingredients for daily meals are changing. With support from the Government of Canada and the Global Environment Facility’s Least Developed Countries Fund, the Canada-UNDP Climate Change Adaptation Facility (CCAF) has been supporting six least developed countries and small island developing states (Cabo Verde, Cambodia, Haiti, Mali, Niger and Sudan) to strengthen climate resilience and enhance food security. To better understand and share the experiences from these six countries, and to celebrate some of the s
As climate change continues to drive food insecurity, addressing the risks of climate change across the value chain – especially agricultural products that are important to food and nutrition security – will yield significant adaptation benefits to vulnerable small producers and rural communities at large. This will support global efforts to end hunger and poverty, build more effective farming practices that reduce greenhouse gas emissions, and accelerate the ambition of Nationally Determined Contributions to the Paris Agreement.
Depuis toujours, l’agriculture repose sur la modification de la constitution génétique des plantes et des animaux. Grâce à la reproduction sélective, d’innombrables générations de cultures et d’animaux ont été sélectionnées en fonction de caractères jugés bénéfiques pour l’être humain.
