Background: Preharvest burning of sugarcane is a common agricultural practice in Florida, which produces fine particulate matter [particulate matter (PM) with aerodynamic diameter ( )] that is associated with higher mortality. Objectives: We estimated premature mortality associated with exposure to from sugarcane burning in people age 25 y and above for 20 counties in South Florida. Methods: We combined information from an atmospheric dispersion model, satellites, and surface measurements to quantify concentrations in South Florida and the fraction of from sugarcane fires. From these concentrations, estimated mortalities attributable to from sugarcane fires were calculated by census tract using health impact functions derived from literature for six causes of death linked to . Confidence intervals (CI) are provided based on Monte Carlo simulations that propagate uncertainty in the emissions, dispersion model, health impact functions, and demographic data. Results: Sugarcane fires emitted an amount of primary similar to that of motor vehicles in Florida. from sugarcane fires is estimated to contribute to mortality rates within the Florida Sugarcane Growing Region (SGR) by 0.4 death per 100,000 people per year (95% CI: 0.3, 1.6 per 100,000). These estimates imply 2.5 deaths per year across South Florida were associated with from sugarcane fires (95% CI: 1.2, 6.1), with 0.16 in the SGR (95% CI: 0.09, 0.6) and 0.72 in Palm Beach County (95% CI: 0.17, 2.2). Discussion: from sugarcane fires was estimated to contribute to mortality risk across South Florida, particularly in the SGR. This is consistent with prior studies that documented impacts of sugarcane fire on air quality but did not quantify mortality. Additional health impacts of sugarcane fires, which were not quantified here, include exacerbating nonfatal health conditions such as asthma and cardiovascular problems. Harvesting sugarcane without field burning would likely reduce and health burdens in this region. https://doi.org/10.1289/EHP9957

“…Nas últimas décadas, políticas governamentais e iniciativas público-privadas têm dado suporte adequado para a adoção de canaviais sem queima, associados a menor impacto ambiental, conservação do solo e proteção à saúde humana (Silva et al, 2021). No Estado de São Paulo, o maior produtor de cana-de-açúcar do país (IBGE 2020), a Lei Estadual n°.11.241/02 estabeleceu que o uso do fogo como método despalhador e facilitador do corte da cana deveria ser abolido de forma gradativa, sendo totalmente eliminado até 2021 em áreas com declive do terreno de até 12% .…”

O Brasil é o maior produtor de cana-de-açúcar do mundo. Com as mudanças nos sistemas de colheita da cana-de-açúcar, há uma quantidade expressiva de palhada que fica depositada sobre o solo, podendo contribuir para o aumento da matéria orgânica do solo (MOS). No entanto, no Brasil já existem diversas Unidades Industriais que processam toda a biomassa da cana para fabricar álcool de segunda geração e/ou gerar energia elétrica, tornando-se assim, uma nova fonte de renda das Usinas e Destilarias. Ao processar toda a biomassa gerada pela cana-de-açúcar, os possíveis efeitos favoráveis sobre as propriedades químicas, físicas e biológicas do solo serão retardados. Vale destacar que a matéria orgânica determina os principais atributos que definem a qualidade do solo, sendo diretamente afetada pelas práticas de manejo. Por meio do estudo da qualidade da matéria orgânica, pode-se além de avaliar a qualidade do solo, ter uma maior compreensão do sistema de produção que este solo comporta. Diante do exposto, o objetivo do presente trabalho, foi de estudar os principais efeitos da retirada da palhada da superfície dos solos no conteúdo de matéria orgânica do solo, indicando estudos que apontam a quantidade ideal de palhada a ser deixada no solo, sem afetar o conteudo de matéria orgânica. Para isto, foi realizado uma intensa busca em bases de dados, de estudos que avaliaram as possíveis implicações da retirada total e parcial da palhada de cana.

“…Harvesting is one of the most important stages of the field processes, as it involves high operating costs and directly influences the material quality (MARTINS et al, 2021). In Brazil, since 2017, sugarcane harvesting should only take place mechanized, due to socioenvironmental issues (CARDOSO et al, 2018;SANTORO;SOLER;CHERRI, 2017;SILVA et al, 2021). Mechanized harvesting promotes benefits to the cropping system, such as soil erosion protection and nutrient cycling.…”

Based on information about the area in which sugarcane will be cultivated, yield ranges can be determined. The yield and cultivar adopted directly interfere in the harvest. Mechanized harvesting has advantages in the sugarcane production, but losses occur in this process. In this sense, the objective was to evaluate the mechanized harvesting quality of two sugarcane cultivars (CTC4 and SP86-0155) in three yield ranges (50 to 70, 71 to 90 and 91 to 120 t ha-1). The experiment was carried out in six areas in the region of the municipality of Jaboticabal-SP. In each area, yield and visible losses were determined at twelve points. The data were submitted to descriptive analysis and as a tool to analyze the harvest quality, the statistical process control (SPC) was used. The results indicate 54% higher losses in high yield ranges, and lower process quality. The cultivar SP86-0155 presented 11% less loss at harvest regarding to the cultivar CTC4, a fact that is related to the cultivars morphological characteristics.
