Biodiversity conservation in agricultural landscapes: the importance of the matrix Repositório Alice
TAVARES, P. D.; UZEDA, M. C.; PIRES, A. dos S..
Agricultural matrices can lead to landscape homogenization, culminating in losses of biodiversity and ecosystem services. Agricultural management is determinant for developing conservation strategies. In this review, we discuss the influence of the agricultural matrix on biodiversity at different scales. Intensive agriculture under agrochemicals and synthetic fertilizers aggravates forest fragmentation processes, compromising conservation habitats. On the other hand, managed matrixes with greater agricultural biodiversity and reduced synthetic inputs tend to favor species? persistence. There is discord regarding the best model to conserve biodiversity in agricultural landscapes, but the land sharing system increases the landscape heterogeneity, ensures...

Results from on-the-ground efforts to promote sustainable cattle ranching in the brazilian Amazon. Repositório Alice
ERMGASSEN, E. K. H. J. zu; ALCÂNTARA, M. P. de; BALMFORD, A.; BARIONI, L. G.; BEDUSCHI NETO, F.; BETTARELLO, M. M. F.; BRITO, G. de; CARRERO, G. C.; FLORENCE, E. da A. S.; GARCIA, E.; GONÇALVES, E. T.; LUZ, C. T. da; MALLMAN, G. M.; STRASSBURG, B. B. N.; VALENTIM, J. F.; LATAWIEC, A..
Agriculture in Brazil is booming. Brazil has the world?s second largest cattle herd and is the second largest producer of soybeans, with the production of beef, soybeans, and bioethanol forecast to increase further. Questions remain, however, about how Brazil can reconcile increases in agricultural production with protection of its remaining natural vegetation. While high hopes have been placed on the potential for intensification of low-productivity cattle ranching to spare land for other agricultural uses, cattle productivity in the Amazon biome (29% of the Brazilian cattle herd) remains stubbornly low, and it is not clear how to realize theoretical productivity gains in practice. We provide results from six initiatives in the Brazilian Amazon, which are...

When enough should be enough: improving the use of current agricultural lands could meet production demands and spare natural habitats in Brazil. Repositório Alice
STRASSBURG, B. B. N.; LATAWIEC, A. E.; BARIONI, L. G.; NOBRE, C. A.; PORFIRIO-DA-SILVA, V.; VALENTIM, J. F.; VIANNA, M.; ASSAD, E. D..
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. However, few investigations have shown the extent to which these lands can meet projected demands while considering biophysical constraints. Here we investigate the improved use of...
