Abstract: As available agricultural and pasture land is rapidly declining worldwide, improved land use and more efficient land occupation becomes a critical issue. In Brazil, land reserves are mostly associated with either underutilized or degraded cultivated pastures. This study shows that land surface phenology derived from moderate spatial resolution satellite imagery can be a very effective method for mapping and understanding the functioning and structure of ecosystems. In particular, and considering the Brazilian savanna landscapes, temporal metrics, such as the start of the season green-up of the vegetative cover and evapotranspiration, can be instrumental for assessing areas converted from natural vegetaion and their responses to a variety of environmental conditions and human-induced pressures.
