Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems.
In the Amazon, slash and burn is the most common technique used by American-Indians, small farmers and even big ranches to transform forests into rural landscapes. The basis of food subsistence for diverse populations (rice, corn and bean), slash and burn is also a must for the plantation of cocoa, coffee, palms and pastures. The Amazonian rural landscape is currently dominated by pastures, occupying around 80 % of the deforested surface.
Traditional shifting cultivation in the Amazon region has caused negative environmental and social effects due to the use of fire. This type of agriculture has been criticized because it results in emission of large amounts of carbon into the atmosphere and a loss of soil productive potential.
Small-scale farmers in the Brazilian Amazon collectively hold tenure over more than 12 million ha of permanent forest reserves, as required by the Forest Code. The trade-off between forest conservation and other land uses entails opportunity costs for them and for the country, which have not been sufficiently studied. We assessed the potential income generated by multiple use forest management for farmers and compared it to the income potentially derived from six other agricultural land uses.
Le développement de l'agriculture organique au Brésil prend des formes multiples. Au travers de leur expérience de l'AO, dans une communauté proche de trois métropoles, de petits maraîchers d'Ibiúna (São Paulo) créent des entités collectives et expérimentent de nouvelles pratiques sociales.
Precision agriculture (PA) is growing considerably in Brazil. However, there is a lack of information regarding to PA adoption and use in the country. This study sought to: (i) investigate the perception of growers and service dealership about PA technologies; (ii) identify constraints to PA adoption; (iii) obtain information that might be useful to motivate producers and agronomists to use PA technologies in the crop production systems.
En dépit de son vaste potentiel agricole, l’Afrique est de plus en plus tributaire des importations alimentaires du reste du monde pour satisfaire ses besoins de consommation. La production alimentaire n’a pas suivi le rythme de la croissance démographique et plus de 80 % des gains de production depuis 1980 proviennent de l’expansion des superficies cultivées plutôt que d’une meilleure productivité des zones déjà cultivées (Rakotoarisoa et al. 2012).
This report deals with the adoption of technological innovations in the case of rice farming in Togo.
The following is a summary that introduces the report.
L’objectif de cet article est de décrire et de comprendre les comportements à innover des coopératives agricoles. Il mobilise le cadre théorique de l’économie de l’innovation. Exploitant une enquête postale sur la région Midi-Pyrénées, la typologie des comportements à innover obtenue après analyse statistique permet d’identifier cinq classes d’entreprises coopératives. Du fait de leur importance à l’amont des filières et des territoires, les coopératives apparaissent comme des intermédiaires incontournables pour répercuter les contraintes de l’aval auprès des exploitants agricoles.
L’agriculture familiale est l’une des formes d’organisation de l’agriculture à travers le monde. Elle se décline en fait en une multiplicité de types concrets repérables au niveau des exploitations agricoles .
