Developed the thesis "Soil Organic Carbon as a function of land uses", comparing Soil Carbon levels under different land uses: Forest, Pasture and Agriculture. Since 1999, ahead of Atlântica Simbios Environmental Consulting, has developing and coordinating Native Vegetation Restoration Projects in the Brazilian states of Bahia, Mato Grosso do Sul, Pará and São Paulo. Also has developed deep knowledge on Forest Carbon Projects, GHG Emissions Inventories in Agriculture, Livestock and Forestry activities. In 2012, invited by Rabobank, participated the discussions of "Think PINC: Securing Brazil’s food, water and energy with Proactive Investment in Natural Capital" Report, promoted by the Oxford Centre for Tropical Forests. In 2014 presented the seminar "Land use and beef production in Brazil -- Development Plans and Greenhouse Gases Emissions" at the Department of Energy and Environment at Chalmers University of Technology, Gothenburg, Sweden.edit

Since sugarcane areas have increased rapidly in Brazil, the contribution of the sugarcane production, and, especially, of the sugarcane harvest system to the greenhouse gas emissions of the country is an issue of national concern. Here we analyze some data characterizing various activities of two sugarcane mills during the harvest period of 2006-2007 and quantify the carbon footprint of sugar production. According to our calculations, 241 kg of carbon dioxide equivalent were released to the atmosphere per a ton of sugar produced (2406 kg of carbon dioxide equivalent per a hectare of the cropped area, and 26.5 kg of carbon dioxide equivalent per a ton of sugarcane processed). The major part of the total emission (44%) resulted from residues burning; about 20% resulted from the use of synthetic fertilizers, and about 18% from fossil fuel combustion. The results of this study suggest that the most important reduction in greenhouse gas emissions from sugarcane areas could be achieved by...

Organic matter is one of the most sensitive attributes of the soil triggered by changes in management systems. This study aimed to assess the distribution and carbon stocks depending on the land use and soil depth. There were collected soil samples from native forests, pastures and crops in ten locations, where the three land uses are found in adjacent areas in four depths (0-10 cm, 10-20, 20-40 and 40-60 cm ). The experimental design was a Split-Plot having land uses as main treatments and depths as secondary treatments. The highest concentration of total soil organic carbon (SOC) was obtained in the 0 to 10 cm layer. The variation between the mean SOC had the following order: forest (18.02 g dm-3)> grassland (15.80 g dm-3)> agriculture (12.45 g dm-3). Between forest and pasture there was no difference between the mean values of SOC. There was difference between soils under forest and agriculture with a decrease of 30.91%. The concentration of dissolved organic carbon (DOC) presented the following order between types of land use: forest (236.42 mg dm-3)> grassland (151.41 mg dm-3)> agriculture (86.76 mg dm-3), and showed a difference of 35.95% between forest and grassland, and 42.70% between grassland and agriculture. The highest levels of DOC were found in the 0 to 10 cm layer and the order between types of land use was: forest> pasture> agriculture. Same effect was obtained in the layer 10 to 20 cm and, in the layer 20 to 40 cm, difference was observed between soils under forest and soils under agriculture, higher in the first one. There was no difference in the levels of DOC between types of land use in the layer 40 to 60 cm. The average stock of SOC did not differ between land uses when it was considered the depths of 0-10, 10-20, 20-
40, 40-60 and 0-60 cm. The average stock of SCO considered when the layer 0-20 cm showed a difference of 23.14% between soils under grassland (48.62 Mg ha-1) and in agriculture (37.37 Mg ha-1). Positive correlation was found between SOC and DOC. There was also a positive correlation between SOC and clay content. It was concluded that the conversion of forest to pasture or crops caused decrease in SOC and DOC. The decrease of SOC in the soil profile is less pronounced in soils under pasture. Soils under agriculture had the lowest SOC. The superficial layers presented the highest concentration of SOC.
