Canasat - Area
Annual monitoring of the cultivation of sugarcane in the following classes: ratoon, expansion, under renovation (18 months) and renovated (18 months).
Maps, charts and tables of the area cultivated with sugarcane
Study Area
The South-Central region of Brazil is currently responsible for 88% of the sugarcane production in Brazil. Annual information is available for the following states and crop years:
  • States of Goiás (GO), Minas Gerais (MG), Mato Grosso (MT), Mato Grosso do Sul (MS), Paraná (PR) and São Paulo (SP): since crop year 2003;
  • States of Espírito Santo (ES) and Rio de Janeiro (RJ): since crop year 2010.
Products
Maps and graphs, and also tables of the cultivated sugarcane area by municipalities and by states for the entire South-Central region of Brazil.
Methodology
The mapping procedure is carried out once a year using free of cost remote sensing images available at INPE/DGI and acquired by the Landsat, CBERS and Resourcesat-I satellites.
The image processing and interpretation is performed using the SPRING software. More detailed information about the Canasat-Area Project can be obtained in the article Studies on the Rapid Expansion of Sugarcane for Ethanol Production in São Paulo State (Brazil) Using Landsat Data and also in other publications.
Canasat - Harvest
Annually identify and map the sugarcane harvest type, with and without the pre-harvest burning practice.
Maps and charts of the type of harvesting sugarcane
Study Area
São Paulo State since crop year 2006/07.
Products
Maps, graphs and tables of the type of sugarcane harvest by municipality and by Administrative Region of São Paulo State.
Methodology
The mapping of the sugarcane harvest type is carried out yearly and is based on both the annual sugarcane maps of the Canasat Project Canasat Project), and the remote sensing images from the Landsat-5 satellite and alternatively from Landsat-7, CBERS-2 and Resourcesat-I satellites, that are freely available at INPE/DGI. The image processing and interpretation are carried out using the SPRING software. More detailed information about the Canasat-Harvest Project can be found in: Remote Sensing Images in Support of Environmental Protocol: Monitoring the Sugarcane Harvest in São Paulo State, Brazil and also in other publications.
Motivation
The São Paulo State Law 11.241 establishes the extinction of the pre-harvest straw burning practice by the year 2021 for most of the sugarcane cultivated areas in São Paulo State. The Green Ethanol Protocol is an initiative of both the State government and the sugarcane sector to anticipate the end of the pre-harvest burning practice to the year 2014. It also foresees the annual concession of a certificate of conformity to producers that adopt best practice management.
