Natural resource management practices, such as the System of Rice Intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of system technologies for farmers are often debated. Impacts seem to be context-specific, which is especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research.
Food systems contribute 19%–29% of global anthropogenic greenhouse gas (GHG) emissions, releasing 9,800–16,900 megatonnes of carbon dioxide equivalent (MtCO2e) in 2008. Agricultural production, including indirect emissions associated with land-cover change, contributes 80%–86% of total food system emissions, with significant regional variation. The impacts of global climate change on food systems are expected to be widespread, complex, geographically and temporally variable, and profoundly influenced by socioeconomic conditions.
This paper provides a review of agronomic management practices supporting sustainable crop production systems and intensification, and testifying to developments in the selection of crops and cultivars. The paper also describes crop farming systems taking a predominantly ecosystem approach and it discusses the scientific application of this approach for the management of pest and weed populations.
Le Programme 2012-2013 de l’Initiative 3N vise à :
- Accroître et diversifier les productions agro-sylvo-pastorales et halieutiques pour assurer la sécurité alimentaire et nutritionnelle des populations nigériennes;
- Augmenter les revenus des producteurs et des acteurs des filières agricoles par l’amélioration de la conservation, la transformation et la commercialisation des produits agro-alimentaires ;
- Améliorer les capacités nationales de prévention et de gestion des crises et catastrophes et la résilience des populations vulnérables.
Ce manuel est destiné aux formateurs des organisations paysannes (OP) et à leurs membres en Afrique sub-saharienne. Le but étant de fournir une formation sur les techniques et opérations après-récolte afin d’améliorer la qualité des grains et ainsi de permettre l’augmentation des revenus et l’amélioration de la sécurité alimentaire des agriculteurs participants au programme. Dans le passé, les formations sur les opérations après-récolte n’ont pas été normalisées entre les différents pays membres du programme P4P.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is a research in development program which aims to foster innovation to respond to community needs, and through networking and social learning to bring about development outcomes and impact at scale. It aims to reach the poorest and most vulnerable communities that are dependent upon aquatic agricultural systems. AAS uses monitoring and evaluation to track progress along identified impact pathways for accountability and learning.
This report describes the 2012 NAIS Assessment was piloted in 4 countries: Botswana, Ghana, Kenya and Zambia. Data were collected through a survey questionnaire, open-ended interview questions, and data mining of secondary sources. A team led by a national coordinator took charge of data collection from various partner organizations in each country.
Present-day society asks more from agriculture than just the production of food. Agriculture is now required to be concerned with the quality of food, ecosystem services, inclusion of marginalized populations, revitalization of rural territories, energy production, etc. This opening up of the future of agriculture encourages rural actors to experiment with new farming systems, using imagination, creativity and determination to replace dominant models. At the same time, low-cost mass-production systems continue on their way, with promises of a future based on green technologies.
Despite its vast agriculture potential, Africa is increasingly dependent on food imports from the rest of the world to satisfy its consumption needs. Food output has not kept pace with population growth, and more than 80 percent of production gains since 1980 have come from the expansion of cropped areas rather than from greater productivity of areas already cultivated. This paper looks at the current requirements for seed trade in Africa, the obstacles, status of ongoing plans for regional harmonization, challenges of harmonization, and opportunities for near-term improvement.
En dépit de son vaste potentiel agricole, l’Afrique est de plus en plus tributaire des importations alimentaires du reste du monde pour satisfaire ses besoins de consommation. La production alimentaire n’a pas suivi le rythme de la croissance démographique et plus de 80 % des gains de production depuis 1980 proviennent de l’expansion des superficies cultivées plutôt que d’une meilleure productivité des zones déjà cultivées (Rakotoarisoa et al. 2012).
