Since sugarcane areas have increased rapidly in Brazil, the contribution of production, and, especially, harvest system to greenhouse gas emissions country is an issue national concern. Here we analyze some data characterizing various activities two mills during period 2006-2007 and quantify carbon footprint sugar production.According our calculations, 241 kg dioxide equivalent were released atmosphere per a ton produced (2406 hectare cropped area, 26.5 processed). The major part total...
Abstract There is a growing need for all productive sectors to develop greenhouse gas ( GHG ) mitigation techniques reduce the enhanced effect. However, challenge agricultural sector reducing net emissions while increasing production meet demands food, fiber, and biofuel. This study focuses on changes in balance when sugarcane areas are converted from burned harvest BH green GH , mechanized harvest), including caused by adoption of conservationist practices such as reduced tillage 4‐month...
Abstract New management strategies should be identified to increase the potential of bioenergy crops minimize climate change. This study quantified impact sugarcane ( Saccharum spp.) harvest systems, straw and soil on carbon dioxide CO 2 ) fluxes prior crop replanting carried out February 2010 in southern Brazil. The studied was classified as Haplustult USDA Soil Taxonomy). Three systems were considered: burned BH green with maintained GH SM or removed from SR surface. Our hypothesis is that...
Abstract Land degradation has been a global environmental issue, and its cause includes poorly managed grazing. Quantitative information is needed to support policy actions for food water security development. The objective of this study was assess characterize CO 2 –C emissions in degraded (DP) pasture (MP) areas located close one another, describing their spatial–temporal variability any correlation with possible controlling factors. A grid 100 × m 102 sample points each area set up....
We studied the Paraíba do Sul river watershed, São Paulo state (PSWSP), Southeastern Brazil, in order to assess land use and cover (LULC) their implications amount of carbon (C) stored forest between years 1985 2015. The region covers an area 1,395,975 ha. used images made by Operational Land Imager (OLI) sensor (OLI/Landsat-8) produce mappings, image segmentation techniques vectors with homogeneous characteristics. training samples for classification validation were collected from segmented...
Food production in sustainable agricultural systems is one of the main challenges modern agriculture. Vegetable intercropping may be a strategy to mitigate greenhouse gas (GHG) emissions, replacing monoculture systems. The objective identify emissions sources and estimate GHG collard greens, New Zealand spinach chicory. Four scenarios were evaluated: ICS - greens spinach; MCS ICC chicory; MCC boundaries' reach from "cradle-to-gate" calculation performed using IPCC methodology specific...
Estudou-se a interação genótipo x ambiente de doze cultivares alface, sendo quatro do grupo lisa (Babá Verão, Karla, Nacional e Elisa), crespa (Simpson, Hortência, Verônica Grand Rapids) americana (Laidy, Tainá, Lucy Brown Raider). Os tratamentos foram constituídos pelo cultivo da alface em dez ambientes (casa vegetação, túnel baixo cultivo, com sombrite, agrotêxtil campo, na presença ausência mulching). Foram utilizados dois períodos agosto novembro 2001 março junho 2002 Jaboticabal. Cada...
This study aims to assess the additional Greenhouse gas (GHG) emissions affected by straw removal from soil surface in sugarcane areas, including measurement of short-term CO2-C plus associated with recovery and transport operations bales until industry gate (diesel emissions) estimated N2O emission, comparing leaving all on surface. Taking into account main sources evaluated (soil CO2, diesel straw), total GHG 6.9 Mg Dry Matter ha-1 (27%) was at 1423 kg CO2eq ha-1, resulting a carbon...
Abstract Grazing areas represent the largest agricultural in Brazil, occupying more than 172 million hectares, about 20% of land (IBGE, 2007). Despite large degraded pasture, little information exists temporal variation soil properties including nutrients and carbon dynamic (Cerri et al., 2004). This study aimed to measure FCO 2 from managed pasture areas, describing their variability correlated environmental variables. Our was carried out at two located Mococa city, Sao Paulo State Brazil....
The change in land use and cover caused by the expansion of sugar cane a part State São Paulo between 1988 2016 was mapped. mapping done automatically using orbital imagery from Landsat Thematic Mapper (TM) satellite manual delimitation polygons. During period under study, sugarcane areas more than doubled, expanding 1.2 million hectares, mainly over pasture, annual crops citrus. Faced with shortage land, energy sector must increase productivity, but sustainable way. To meet this challenge,...
