Livestock in the Amazon is mainly limited by the lack of forage biomass production in the dry season. The sensitivity of pasture to drought depends on pasture management and on certain natural factors that enable the grass cover to stay green for longer under low rainfall. The sustainability of livestock production systems depends on identifying th...

Beyond reducing deforestation, the control of forest degradation, the promotion of forest restoration, and the improvement of agricultural practices in the Brazilian Amazon are becoming increasingly important for sustainable development. To enable farmers and authorities to organize their landscapes and optimize both agricultural practices and the...
Article
In the Brazilian Amazon, extensive cattle ranching expansion has been the main driver of deforestation since the last four decades and led to large extent of degraded lands. Great expectations have been placed in land use intensification through the restoration of degraded pastures, improving livestock performance and conserving forest. Despite suc...

We present a 1:100,000 scale soil texture map of Paragominas county (Pará, Brazil), covering 19,330 km². The method allows rapid production of a soil texture map of a large area where the strength of a duricrust controls the relief. It is based on an easily accessible explanatory variable, topography, which is represented using a Digital Elevation...
Article
Deforested areas of the Amazon rainforest in western Brazil have been converted into intensively managed Brachiaria bryzantha-dominated pastures characterised by poor productivity. However, such systems may be spurring ecological intensification, which would unlock the tremendous agricultural and ecological potential of such lands and encourage inn...
Article
The Brazilian Amazon Region is best known for his forest for its pasture. Yet their expansion is permanent, after five decades of a cattle ranching colonization process, something unique in the rangeland world. Along deforestation frontier, farmers are going on, they occupy public or indigenous land, beginning the emergence of new region. The autho...

Land use governance in the Brazilian Amazon has undergone significant changes in the last decade. At the national level, law enforcement capacity has increased and downstream industries linked to commodity chains responsible for deforestation have begun to monitor some of their suppliers' impacts on forests. At the municipal level, local actors hav...

... In the period between 2011 and 2017, the anthropized areas had an increase of approximately 39%, resulting, consequently, in the reduction of forest cover around the Lake (Figure 8). In research on land adequacy to guide landscape restoration in the Amazonia, mapping is a tool that can contribute to reducing deforestation, controlling forest degradation, promoting forest restoration, and improving practices [40]. In the Brazilian Amazonia, the social actors involved in the mapped areas can better organize and plan their landscapes In research on land adequacy to guide landscape restoration in the Amazonia, mapping is a tool that can contribute to reducing deforestation, controlling forest degradation, promoting forest restoration, and improving practices [40]. ...
... Despite all the potential problematic implications of "troca de areas", it is important to recognize that it aligns with the trend among landholders in Paragominas to increasingly adopt intensification strategies based on spatial criteria (Plassin et al., 2017). Landholders are intensifying production on available clayey plateaus and abandoning less suitable areas, generating an incipient forest transition (Mather, 1992;Mather and Needle, 1998) in areas not suitable for soybean production. ...
... Bisrat and Berhanu (2018) determined the water-storing sites of Ethiopia with the Topographic Wetness Index (TWI) and Normalized Difference Vegetation Index (NDVI) along with satellite data and concluded it is a cost-effective, noncomplicated potential GIS-based technique for representing water work. Soil is the permeable, biologically agile layer that has grown in the Earth's crust (Laurent et al., 2017). Ayele et al. (2019) in their research examined the properties of soil around the watersheds of Rift Valley basins, its effect on physiochemical properties, and tried to establish a relationship between topographic features and soil characteristics. ...
... Ceci est d'autant plus pertinent dans un contexte de demande de services écosystémiques, de conservation de l'environnement et d'une agriculture fondée sur de bonnes pratiques ( Cerri et al. 2018). Après la déforestation, dans le cas général, l'élevage est l'une des premières activités mises en place, conformément à un processus commun à la plupart des dynamiques historiques de colonisation du Brésil (Poccard, Bendahan, et Carvalho 2015). Cependant, l'arrivée du soja est un élément nouveau dans cette dynamique, occupant à la fois les zones auparavant déboisées et induisant ou non de nouvelles déforestations. ...
... These aspects relate directly to the patterns of interactions among multiple agents at the municipal level. As reported in our case studies and extensively documented in Paragominas, attributes such as the mayoral leadership, public agencies engagement, local pride, social cohesion, and financial and institutional support were critical elements steering diverse local stakeholders towards collectively responding to the LPM policy (Nepstad, 2017;Piketty et al., 2015;Viana et al., 2016), notably among local agricultural elites (Londres et al., 2021). However, these factors alone do not explain success if detached from the broader historical and current context within which municipalities are embedded. ...
