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 book is about the challenges and practical realities of building the capacity to innovate. It describes the experiences of the Research Into Use (RIU) programme, a five-year, multi-country investment by DFID that aimed to extract development impact from past investments in agricultural research. Specifically, it explores different approaches through which innovation capacities were built.
Seed is the starting point of plant life, and hence the most fundamental input of agriculture. A seed system that assures the availability of the desired quality of seed to the producer at the right time is indispensable for his farming enterprise. In the case of the potato crop, the seed most commonly used is strictly speaking no seed, but a tuber. The constraints and opportunities in seed potato systems in East Africa are of a combined social, economic and technical nature.
This research explores the role of innovation platforms and how they relate to IAR4D and the innovation system perspective, with treatment both at the theoretical and case study level (Africa). The chapters of the book take up several sticky issues and engage with them critically: policy pathways, gender equity and inclusion, and knowledge and information sharing. The introductory chapter provides context on food crops, food security and the importance of women in production, processing and trade.
This book describes how the Alliance for a Green Revolution in Africa (AGRA) has been trying to improve markets for staple foods in Africa through its Market Access Programme. It describes 13 projects from eight countries (Burkina Faso, Ghana, Kenya, Malawi, Mozambique, Rwanda, Tanzania and Uganda) that the programme has supported. The book does not attempt to describe the cases in detail. Rather, it focuses on particular aspects in order to derive lessons from which the project managers, AGRA and other development organizations can learn.
In this book, West African research associates from the CoS-SIS programme describe how they initiated innovation platforms and facilitated the different steps in a CIG cycle. The stories show that the facilitation of innovation platforms is not easy: it requires specific skills and a lot of time, and is very much determined by the context. But they also illustrate that there are creative ways of dealing with the challenges and unpredictable situations that facilitators face.
In-depth analysis of the role and capacity development needs of farmers organization in innovation processes, using the evidence from a number of case studies from contemporary SSA agriculture. Experiences indicate that Farmers’organizations (FOs) can play an important role in sharing knowledge-for-innovation by initiating multi-actor platforms for interactive learning and by implementing joint activity programmes (including use of the media) with extension services on a cost-sharing basis.
This report provides a synthesis of all findings and information generated through a “stocktaking” process that involved a desk study of Prolinnova documents and evaluation reports, a questionnaire to 40 staff members of international organizations in agricultural research and development (ARD), self-assessment by the Country Platforms (CPs) and backstopping visits to five CPs. In 2014, the Prolinnova network saw a need to re-strategise in a changing context, and started this process by reviewing the activities it had undertaken and assessing its own functioning.
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.
