Scroll to the bottom of the page to find links to Satelite images from e.g. Landsat. The report (“relatório 2008-2009”) sums up the results from the monitoring of deforestation of the caatinga (2002-2008), it’s in portguguese, though.
(I admit thatI use our blog to collect some links that I’m afraid to forget in the near future, if I do not put them somewhere… the favourite-list is no option, since I work on too many different PCs. And maybe here it is still useful for others?)
