Les systèmes alimentaires durables sont essentiels pour assurer la sécurité alimentaire et une alimentation saine pour les générations futures. Pour faire la transition vers la durabilité, de nombreuses activités du système alimentaire doivent se transformer, et une myriade d’acteurs à travers le monde doivent agir localement. Certains changements sont plus faciles à mettre en place que d’autres, mais savoir comment naviguer à travers ces changements pour promouvoir des modes de consommation et de production durables exige un ensemble de compétences complexes.
Los sistemas alimentarios sostenibles son fundamentales para garantizar que las generaciones actuales y futuras tengan seguridad alimentaria y puedan llevar una dieta saludable. Para hacer la transición hacia la sostenibilidad, es necesario reconstruir muchas actividades del sistema alimentario, y un sinnúmero de actores en todo el mundo están empezando a actuar localmente. Si bien algunos cambios son más fáciles que otros, saber cómo navegar a través de ellos para promover prácticas de consumo y producción sostenibles requiere un conjunto complejo de aptitudes.
Food insecurity and the weak position of smallholders in food value chains are key challenges in many low- and middle-income countries in sub-Saharan Africa. In order to increase food security and make agricultural value chains more inclusive, donors, governments and researchers increasingly stimulate partnerships between multiple actors, in which knowledge exchange, joint learning and knowledge co-creation play a central role in reducing the time lag between research findings and their translation into practical outcomes.
Food systems are at a crossroads. Profound transformation is needed to address Agenda 2030 and to achieve food security and nutrition (FSN) in its four dimensions of availability, access, utilization and stability, and to face multidimensional and complex challenges, including a growing world population, urbanization and climate change, which drive increased pressure on natural resources, impacting land, water and biodiversity. This need has been illustrated from various perspectives in previous HLPE reports and is now widely recognized.
Les informations géospatiales et leurs produits dérivés, conçus pour contribuer à la définition des politiques publiques agricoles, sont peu utilisés en Afrique. Les infrastructures, la formation et les compétences manquent ; les activités de recherche et développement sont dispersées et insuffisantes. Mais, surtout, les besoins restent mal formalisés et l’offre technologique, impulsée par les pays industrialisés, est peu adaptée aux caractéristiques des agricultures africaines.
Fall Armyworm (Spodoptera frugiperda), or FAW, is an insect native to tropical and subtropical regions of the Americas. In the absence of natural controls or good management, it can cause significant damage to crops. It prefers maize, although it can feed on more than 80 additional species of crops including rice, sorghum, millet, sugarcane, vegetable crops and cotton.
This article examines how research on the agriculture and agrifood systems mobilizes the concept of Innovation System (IS). A literature review on the IS provides an analytical framework for determining its theoretical frame of reference, its area of application and its uses.
Many of the world’s food-insecure and undernourished people are smallholder farmers in developing countries. This is especially true in Africa. There is an urgent need to make smallholder agriculture and food systems more nutrition-sensitive. African farm households are known to consume a sizeable part of what they produce at home. Less is known about how much subsistence agriculture actually contributes to household diets, and how this contribution changes seasonally. We use representative data from rural Ethiopia covering every month of one full year to address this knowledge gap.
Improved water management offers a range of benefits to people living in the dryland tropics, where water is scarce. Watershed programmes based on active participation of the rural population bear the potential to ensure food security, contribute to economic growth and help conserve natural resources. An ICRISAT programme in India provides an example of a science-led, knowledge-based approach in this field.
