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.
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.
In Pium, Tocantins state, Brazil, in 2012 Embrapa developed a technology transference project in partnership with the state?s rural extension service for the consolidation of low carbon emissions agriculture. The goal was to recover the degraded grasslands of the Trigueira farm (49°1'37.44"W and 10°24'58.84"S) with low cost using a crop-livestock system.
Brazilian agriculture is facing another expansion cycle to the Cerrado region, more specific in the Northeast. The first agriculture expansion cycle to the Midwest was in seventies encouraged and developed by Brazilian Government with farmers from southern and southeast Brazil, which were traditional small farmers with some experience, low budget and a remarkable determination. All of these efforts after 20 years resulted in an outstanding development of a part of the country with economy based on agribusiness (soybean, corn, cotton, livestock, poultry, swine, etc.).
Le sud du Brésil qui possède un bon potentiel naturel en raison de son climat chaud et humide et de son relief favorable est voué principalement à l’élevage et aux cultures de soja, de riz et de maïs. Cette région, comme d’autres au Brésil, participe à la production de denrées agricoles pour le marché national et international. Elle est ainsi soumise à l’intensification des pratiques dont les impacts sur l’environnement sont notoires. L’étude concerne plus particulièrement le bassin versant de l’Ibicuí (46 800 km²), situé dans le sud-ouest de l’État de Rio Grande do Sul.
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.
