Remote sensing for sustainable sugarcane production

Transcription

1 Workshop Agro-environmental impact of biofuels and bioenergy Remote sensing for sustainable sugarcane production Campinas, 01 December 2011 National nstitute for Space Reseach NP Remote Sensing Division - DSR Laboratory of Remote Sensing in Agriculture and Forestry - LAF Bernardo Rudorff [email protected]

2 Biofuels are an alternative to fossil fuels to mitigate GHG and potential global warming; Brazil is using bioethanol from sugarcane since 1980 s; thanol production from sugarcane is very efficient; n 2003 Brazil started to produce flex cars; 90% of sugarcane in Brazil is cultivated in the South- Central Region; Cultivated sugarcane land went from 4,3 Mha in 2003 to 8,6 Mha in 2011 LUC and crop management have major impacts on GHG mitigation; Remote sensing tools have great potential to monitoring sugarcane crop.

3 The Canasat Project Monitoring of Sugarcane Crop using Remote Sensing mages 1. Mapping and Forecasting Cultivated Area; 2. Monitoring of Harvest Practice; 3. Land Use Conversion Due to xpansion; 4. Time-series to Monitor Land Use Change.
