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.
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.
In this study, it is applies a participatory scenario modelling framework to assess potential societal responses to the impacts of climate change by the mid-21st century, and model consequent land use and land cover change scenarios under different livelihood futures as guided by communities’ members in the areas under investigation. The authors focused their analysis on two montane sites of the Eastern Afromontane Biodiversity Hotspot , the Taita Hills, Kenya, and a montane area north-west of Jimma, Ethiopia
Ethiopian agriculture is changing as new actors, relationships, and policies influence the ways in which small-scale, resource-poor farmers access and use information and knowledge in their agricultural production decisions. Although these changes suggest new opportunities for smallholders, too little is known about how changes will ultimately improve the wellbeing of smallholders in Ethiopia. The authors of this paper examine whether these changes are improving the ability of smallholders to innovate and thus improve their own welfare.
Since 1991, there have been significant changes in utilization of feed resources in the Ethiopian highlands: while use of communal grazing lands and private pastures has declined, use of crop residues and purchased feed has increased. In addition, although use of animal health services and adoption of improved livestock breeds and modern management practices have increased, ownership of various types of livestock has declined.
Agricultural innovation systems require strong linkage between research and extension organizations in particular, and among the various actors engaged in the agricultural sector in general. In the context of Ethiopia and the Amhara regional state, the agricultural research and extension system is characterized by a large number of actors in a fragmented and underdeveloped innovation system, resulting in very low national and regional innovation capacities. Farmers are generally viewed as passive recipients of technology.
There is a considerable shortage of improved seed in Ethiopia. Despite good reasons to invest in this market, private sector investments are not occurring. Using an institutional economics theoretical framework, this chapter analyzes the formal Ethiopian seed system and identifies transaction costs to find potential starting points for institutional innovations.
This paper asks: What have been the impacts of farmer- or community-led (informal) processes of research and development in agriculture and natural resource management in terms of food security, ecological sustainability, economic empowerment, gender relations, local capacity to innovate and influence on formal agricultural research and development institutions?
How effective are multi-stakeholder scenarios-building processes to bring diverse actors together and create a policy-making tool to support sustainable development and promote food security in the developing world under climate change? The effectiveness of a participatory scenario development process highlights the importance of “boundary work” that links actors and organizations involved in generating knowledge on the one hand, and practitioners and policymakers who take actions based on that knowledge on the other.
