Large-scale agriculture is increasing in anthropogenically modified areas in the Amazon Basin. Crops such as soybean, maize, oil palm, and others are being introduced to supply the world demand for food and energy. However, the current challenge is to enhance the sustainability of these areas by increasing efficiency of production chains and to improve environmental services.
In 2010 the Brazilian Government established a goal to reduce the emissions of greenhouse gases (GHG) by agriculture from 36.1 up to 38.9% in ten years (2010 -2020). To contribute for reaching part of this purpose in Tocantins State, Embrapa and other research and extension services partners have been conducting a project of technology transference on sustainable agricultural practices, including integrated crop-livestock-forestry (ICLF), since 2012.
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of re-agro-forestation which can generate environmental benefits in addition to crop production.
Some of the most promising and at the same time some of the most challenging areas of future food production are found in the savannas of South America. Integrating cropping, livestock, and forestry in these regions can increase the eco-efficiency of agricultural production. This chapter presents a case study of an integrated crop, livestock, and forestry system in Brazil. The study area is in Goiás State in the Cerrado region, a vast savanna covering almost one quarter of Brazil's land area.
Brazilian agriculture is a success story. The country that until the 1960s systematically received food donations from abroad. and up to the 1980s was still a large food importer, had its agriculture profoundly changed. The traditional agriculture that prevailed in Brazil until the 1970s was progressively transformed in the following decades into a modern and highly competitive agriculture based on science.
Family farms are by far the most numerous component of the agricultural sector in the Brazilian Amazon. However socially vital for the development of the region, these small landholdings' agricultural and cattle ranching activities frequently overdraw and degrade natural resources, threatening important ecosystem services. Predominant agricultural practices have been marked by shifting cultivation, with intense use of fire and low productivity, causing high rate of destruction of natural forests.
La co-conception de systèmes agricoles innovants est une piste prometteuse pour répondre au défi de l’innovation, notamment pour les exploitations agricoles familiales africaines confrontées à de multiples changements. Mais il faut penser à la place et aux rôles tenus par de multiples acteurs (agriculteurs, conseillers, chercheurs) pour produire les changements souhaités par toutes les parties, et donc réfléchir à la question du partenariat dans le processus.
Dans cet article, à travers l’étude du cas de la filière forêt-bois-papier aquitaine, nous soulignons la nécessité d’intégrer une plus forte prise en compte des ressources naturelles dans les analyses en termes de systèmes d’innovation. Prenant appui sur la principale spécificité de cette filière, à savoir sa forte dépendance à la ressource ligneuse, le présent article est focalisé sur la manière dont cette dépendance configure le système.
Note de synthèse du rapport réalisé par la commission Agriculture et alimentation (C2A) de Coordination SUD. Il met en lumière les enjeux d’une adaptation des agricultures familiales aux changements climatiques sous l’angle des politiques publiques à partir de l’étude de cas des politiques mises en place au Costa Rica, au Niger et au Vietnam.
Cet article analyse les conditions d’accès aux connaissances dans l’univers des politiques publiques agricoles et leurs conséquences en termes de verrouillage technologique sur des solutions techniques dépendantes de l’usage de pesticides. À partir de l’identification des réseaux d’action publique impliqués dans le développement de l’Agriculture de conservation (AC), il montre une situation d’inégalité entre acteurs pour l’accès aux ressources permettant de développer des techniques innovantes.
