Prospects of the sugarcane expansion in Brazil<br />

It is important <strong>to</strong> clarify the available sources of data regarding sugarcane area in Brazil, since<br />

di�erent ones are used for di�erent purposes here. �e Brazilian Institute for Geography<br />

and Statistics (IBGE) is the Brazilian o�cial organization which provides data on crops<br />

area, production, yield, and several others variables. For estimation of planted and harvested<br />

sugarcane area, two IBGE databases can be used: one from the systematical survey on<br />

agricultural production (LSPA – Levantamen<strong>to</strong> Sistemático da Produção Agrícola) and<br />

the other from the agricultural production by municipality (PAM – Produção Agrícola<br />

Municipal). While the former includes all area occupied with sugarcane – which consists of<br />

areas <strong>to</strong> be harvested and new areas, <strong>to</strong> be harvested only next year – the latter just includes<br />

harvested area in a certain year 4 . PAM data is available for all geographic scales, from 1990<br />

<strong>to</strong> 2006 while LSPA data are forecasts from previous and current years subjected <strong>to</strong> <strong>change</strong>.<br />

4 <strong>Sugarcane</strong> crop is harvested yearly for 5 or 6 consecutive years. In general, a�er that period the sugarcane �eld is<br />

renewed and generally rotated for soil improvement during one season with a crop from the Leguminosae family.<br />

Planted area (or <strong>to</strong>tal land occupied by sugarcane), therefore, is the area available for harvest of sugarcane plus<br />

the area of sugarcane that is being renewed.<br />
