The MODIS images acquired since the year 2000 were transformed to a vegetation index (EVI2, two-band Enhanced Vegetation Index) with pixel size of 250 m. This study aims to use these time series to identify land use changes (LUC) based on the temporal profile of EVI2 values of deforested polygons between 2007 and 2011 within the context of the Soy Moratorium. Deforested polygons were divided in two strata: with and without soy in crop year 2010/11. From the MODIS/EVD time series the following classes were identified: forest, degraded forest, total clearing of the area, regrowth of forest, regrowth with pasture, pasture, agriculture, and soy. For stratum 1, the dominant LUC trajectory was: forest — degradation — regrowth / regrowth with pasture. In the second stratum it was observed two main LUC trajectories: 1) forest — degraded forest — total clearing of the area — annual crop (rice) — soy; and 2) forest — total clearing of the area — annual crop (rice) — soy. For most samples of stratum 2 the LUC trajectory was agriculture (e.g., rice) between total clearing and soy cultivation. These patterns occurred on average over two harvests, which may be considered the necessary time for soil correction and total removal of above ground stumps and roots to enable mechanized soy harvesting. The fast evaluation of one hundred polygons during 11 years was only possible due to the virtual globe to visualize the MODIS time series that proved to be an important tool to improve the understanding of LUC dynamics in the Amazon region. 1. INTRODUCTION The majority of the net carbon emissions in Brazil is estimated to come from land use change (LUC), in particular due to the conversion of forest to agricultural land (BRASIL, 2008). During the past few decades the main hotspots of this conversion have been concentrated in the southern and southeastern Amazon regions where most of the expansion of the agricultural frontier takes place (Alves, 2002; Fearnside, 2005; Skole and Tucker, 1993). Large scale agricultural activity in the Amazon began in the 1970s. During this period and throughout the following decades several governmental programs such as National Integration Program (PIN), Program for Land Redistribution and Stimulation of Agribusiness in the North and Northeast (PROTERRA), and Advance Brazil and were promoted to incentivize colonization, development and integration of the Amazon into the national economy. In addition to these programs the easy credit, the construction of highways, and the vast offering of land at irresistible prices attracted many farmers from southern Brazil (Laurance et al, 2001; Nepstad et al., 2002). The opportunity to guarantee ownership through land tenure or by proof of productive use of the land also attracted farmers and speculators to the Amazon (Hecht et al., 1988, Alston et al., 2000). Among the government investments for the viability of the agricultural production in this region, programs for genetic improvement and adaptation of soy to low latitude regions were developed by EMBRAPA (Sousa, 1990) With new technologies and seeds adapted to tropical conditions, the cultivated crop area increased rapidly, and soy cultivation became one of the main economic activities, particularly in the state of Mato Grosso. Beginning in the 1990s, the expansion of the agricultural frontier in the Amazon started to be driven by market forces. For example, the demand for meat in the Middle East and Russia, and for soy in China (Fearnside, 2001; Macedo et al., 2012; Nepstad et al., 2006; Morton et al., 2006). With the increase in global demand for food, which was not entirely met by increases in agricultural productivity, the conversion of forest to agriculture became a market solution and, at the same time, a major environmental problem. This insight is reason of the increase on environmental awareness since the conservation of forest land became critical in order to minimize the effects of global climate change. In this way, deforestation in the Amazon that was initially fomented by public policies started to be severely combated by government and Non-Governmental Organizations (NGOs). Even the market has adopted some measures to contain deforestation. Some of these actions are: 1) the establishment in 2003 of the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (P/ano de Acáo para Prevencáo e Controle do Desmatamento na Amazónia Legal - PPCDAM) (BRASIL, 2008); 2) the Soy Moratorium in 2006 (Rudorff et al., 2011) and; 3) the Beef Moratorium in 2009 (Boucher et al., 2011). Slowing down the advance of soy production in recent deforested land in the Amazon has also been the goal of several NGOs since the beginning of the 2000s. Greenpeace stood out by advertising the negative impact of soy produced in deforested land in the Amazon, in front of McDonald's restaurants in Europe. In addition to the protests, Greenpeace
