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.
Au Brésil, la diffusion du modèle de gestion intégrée des ressources en eau varie fortement selon l’environnement socio-territorial. Le Sud présente un dynamisme certain s’appuyant sur des initiatives locales. Les acteurs locaux sont organisés en comité de bassin et développent des actions pour améliorer la gestion des ressources. Dans le Nordeste, la marche vers ces nouveaux modes de gestion paraît difficile tant les inerties sociales et culturelles freinent un partage réel du pouvoir, des ressources et des coûts.
En matière de semences, on oppose souvent un modèle orienté vers le business à un modèle orienté vers l’agriculture paysanne. Ces deux modèles ont des implications socio-économiques différentes, aussi bien en termes d’emplois, que d’autonomie des agriculteurs ou de biodiversité. Les agricultures paysannes des pays du Sud ont-elles le poids et l’influence politique nécessaires pour faire prévaloir leurs modèles semenciers ? C’est la question que nous explorons dans ce dossier.
The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history.
The main goal of this report is to provide a brief summary of land-use change in Amazonia within the focus countries of Bolivia, Brazil, Colombia, Ecuador and Peru. This report will mainly focus on the analysis and discussion of land-use change status and trends since 1970’s, a period when considerable changes started to be evident. Analyses were supported from a literature review and land use databases and maps for Andean countries (CIAT) and Brazil (INPE).
This document summarizes the fifteen projects that were selected by a panel of international experts as those which best represent the technological, institutional and organizational innovations carried out with and by small farmers – known as family farming - in LAC. This is the result of a hemisphere-wide competition organized in 2012 by FONTAGRO, with the aim of (1) showcasing success stories in which innovations having positive economic, social, and environmental impacts have been implemented and, (2) raising awareness regarding the importance of investing in innovation.
This report assesses trends in investments, human resource capacity, and research outputs in agricultural R&D -excluding the private (for-profit) sector- in LAC. It is an update of Stads and Beintema (2009), covering a more complete set of countries and focusing primarily on developments during 2006-2012/2013.
Public-private partnerships are a new way of carrying out research and development (R&D) in Latin America's agricultural sector. These partnerships spur innovation for agricultural development and have various advantages over other institutional arrangements fostering R&D. This report summarizes the experiences of a research project that analyzed 125 public-private research partnerships (PPPs) in 12 Latin American countries. The analysis indicates that several types of partnerships have emerged in response to the various needs of the different partners.
This chapter analyses the functioning of the Brazilian agricultural innovation system. It discusses the role of the different actors and describes governance mechanisms to define priorities and evaluate performance. It analyses trends in agricultural R&D expenditure and sources of funding, the role of intellectual property protection in fostering knowledge markets, and outlines mechanisms used to facilitate knowledge transfers, including collaboration at the national level and the adoption of innovation at the farm or firm level.
This paper synthesizes Component 2 of the Regoverning Markets Programme. It is based on 38 empirical case studies where small-scale farmers and businesses connected successfully to dynamic markets, doing business with agri-processors and supermarkets. The studies aimed to derive models, strategies and policy principles to guide public and private sector actors in promoting greater participation of small-scale producers in dynamic markets. This publication forms part of the Regoverning Markets project.
