The Pantanal is the largest seasonal fl ooded region in the world and covers around 146,000 square kilometers in Brazil, Bolivia and Paraguay. Although the fl oodplain is relatively in- tact, with 76% of native habitat well preserved, the upper lands are heavily impacted by the expansion ...
Brazil is home to the Amazon basin and its rainforests, but it is by no means the only country with deforestation problems. Honduras has lost half of its forest cover and Nigeria has chopped down all but 10 percent of its trees. The Philippines, Ghana, Indonesia and Nepal are among many ...

Crucially, pre-training configurations of model-agnostic meta-learning (MAML) that achieve high accuracies on the idealized Sen12MS target tasks are not optimal for the more realistic DFC2020 tasks with gaps up to 60% in accuracy, as shown in Experiment 1 in Table1. This performance gap is ...
has meant the clearing of forest land in order to make room for agriculture. The clearing of forests has contributed to global warming and has greatly decreased the biodiversity of the planet. The problem of deforestation is especially problematic in tropical countries such as Brazil and I...
