In Sub-Saharan Africa, the rapidly evolving COVID-19, increasing population growth, and exponential expansion in demand for agricultural commodities are putting pressure on available resources, thereby posing immense challenges to the region’s capacity to achieve nutritional security related to United Nations Sustainable Development Goals (SDGs).
Le semis direct est un système de production fondé sur le non-travail du sol. Il intègre une série de pratiques agricoles qui permettent de protéger les sols cultivés de l’érosion, de réduire les consommations de carburants, voire d’augmenter les rendements. Le large succès du semis direct au Brésil, contribue à la compétitivité et à la forte croissance de ses productions tout en préservant les sols. Le système complet du semis direct sous couvert est fondé sur trois principes : le non-labour, la couverture permanente du sol et des rotations culturales.
L’ouest du Rio Grande do Sul est dominé par la culture du soja, du riz et par l’élevage bovin. Dans la partie sableuse, le milieu est affecté par des phénomènes d’érosion produisant des modelés éoliens spectaculaires (arenização) rappelant dans l’imaginaire ceux des déserts. La production agricole est importante ce qui engendre des prélèvements d’eau pour l’irrigation du riz, mais aussi l’utilisation de pesticides pour l’ensemble des cultures. La gestion durable des ressources en eau et en sol de cette région nécessite la mise en place d’action de conservation.
This publication is one of four CABI briefings on climate change. The key messages in this briefing are:
• Farmers need timely, accurate, and clear advice on how to manage pest risks
• Digitally-enabled early warning systems can help farmers adapt and minimize losses
• The complex interactions between pests, plants, and the environment under future climate change scenarios need further research to determine best practices
• Scaling digital climate information services will require a sharp focus on equity and inclusion

Inclusive innovation is the means by which new goods and services are developed for and/or by the billions living on lowest incomes. Although a topic of increasing interest, it has been relatively under-researched and under-conceptualised to date. This article studies arguably the most successful new technology to reach low-income groups: the mobile phone, focusing specifically on its diffusion in Kenya. Systems of innovation are shown to be an appropriate frame for conceptualisation of inclusive innovation.
Scaling represents successful diffusion that ensures sizeable impact and earnings from information and communication technology (ICT) innovations in emerging markets. Practice can still be shaped by dualistic views-innovation vs diffusion, pilot vs scale-up, lead firm vs other actors, technical vs social. Synthesising the literature that challenges these dualities, this paper creates a systemic perspective that is particularly appropriate for scaling of ICT to bottom-of-the-pyramid (BoP) markets.
Le gouvernement de Lula a considérablement amplifié et diversifié le Programme d’Appui à l’Agriculture Familiale (PRONAF), créé par le gouvernement Fernando Henrique Cardoso en 1995. Ce choix affirmé sur la longue durée pour l’agriculture familiale, peut surprendre dans un Brésil qui a toujours, tout au long de son histoire, privilégié l’agriculture « d’entreprise » : latifundia et entreprises agricoles.
This book chapter focuses on dimensions of rural learning in Africa, with a special focus on rice farmers. Four key challenges in rural learning are addressed, namely social inclusion, scaling up, collecting farmer feedback and assessing impact. The potentially powerful role of videos in rural learning is illustrated. Experiences from Africa Rice Center (AfricaRice) and partners are presented alongside other relevant experiences.
The Guidance Note on Operationalization provides a brief recap of the conceptual underpinnings and principles of the TAP Common Framework as well as a more detailed guide to operationalization of the proposed dual pathways approach. It offers also a strategy for monitoring and evaluation as well as a toolbox of select tools that may be useful at the different stages of the CD for AIS cycle.
