Intensity of land use changes in a sugarcane expansion region, Brazil

In the last decades, Brazil has been consolidated as one of the world's largest producers of food, with emphasis on soybeans, sugarcane and beef production. With the opening of new markets and the increase in demand, a competitive scenario was developed among farming activties, resulting in changes in land use and cover. Thus, this study aimed to verify the spatial and temporal land use changes, through intensity analysis, in the microregion of Presidente Prudente, Sao Paulo state, in two time intervals, 2004-2007 and 2007-2015, in addition to determining the relevance of pasture in this context. The identification of land uses occurred through the analysis of the spectrum-temporal pattern of the Normalized Difference Vegetation Index (NDVI) from Moderate Resolution Imaging Spectroradiometer (MODIS), in such a way that six classes were identified, annual crop, water, sugarcane, forest, pasture and urban area. The categories annual crop and sugarcane had more intense variations of losses and gains in the studied time intervals. The category pasture was the primary supplying source of the area, showing a reduction of approximately 180,000 hectares in the analyzed period, losing area with greater intensity for the categories of annual crop and sugarcane.13182197FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2014/26928 -

Susceptibility and exposure to sea level rise in the Sado estuary and in the Arrábida coastal zone

Sea level rising is a major driver of three climate hazards in the Sado estuary and in the Arrábida coastal zone: estuarine flooding, coastal flooding and cliff retreat. In this work, the susceptibility to estuarine flooding, coastal flooding and cliff retreat is assessed for the present and at the end of the century, for the SSP2-4.5 and SSP5-8.5 emission scenarios. The exposure of people and assets to the considered climate hazards is assessed for both the current climatic conditions and those projected for the end of the 21st century
