Assessing the spatial distribution of cultivated pastures in the Brazilian savanna

摘要

According to Zimmer and Correa (1993) most of the regional or state level data about the total area of pastures in Brazil are unreliable. Consequently, the few published data about their spatial distribution are also inaccurate. This is the case of the Brazilian savanna, which covers more than 208 million hectares in the central part of Brazil. On the other hand, information regarding the area and the spatial distribution of pastures in Brazil are essential for meat and milk yield prediction, as well as for pasture degradation monitoring and reclamation, among others.
