A queima de biomassa é capaz de influência a nebulosidade e a precipitação, pois gera aerossóis que  atuam como núcleos de condensação de nuvens (NCN). As séries temporais de ambos os municípios mantiveram um padrão comum de comportamento e nelas pode-se determinar a existência de rupturas que evidenciam a existência de três períodos distintos. O primeiro período foi do inicio das séries (1971 em Botucatu e 1980 em Piracicaba) até 1983, o segundo período foi de 1984 a 2008 e o terceiro período de 2009 até 2012 e 2013. No segundo período houve uma tendência de redução no volume anual de precipitação pluvial. A ocorrência dos três períodos distintos está relacionada com a mudança do uso do solo no Estado de São Paulo, com a expansão das fronteiras agrícolas no norte e centro-oeste do Brasil e com a pratica da queima de biomassa. Palavras-chave: análise de tendência, regressão linear, aerossóis, mudanças climáticas.  LORENZO, J.

F.INFLUENCE OF BURNINGS IN THE BEHAVIOUR OF RAINFALLS IN THE CITIES OF BOTUCATU AND PIRACICABA, SÃO PAULO STATE  2 ABSTRACT This work used the time series of rainfall measured in the meteorological stations of  FCA/UNESP-Botucatu (1971-2013) and of ESALQ/USP-Piracicaba (1980-2012), both located in São Paulo State, aims to verify the possible existence of trends (increase or decrease). Biomass burning can to influence the cloudiness and the rainfall, because it generates aerosols that act as cloud condensation nuclei (CCN). The time series of both cities maintained a similar pattern in the behavior and disruptions that revealed the existence of three distinct periods that can be related to burnings that occur in some Brazilian states. The first period is from the beginning of the series (1971 in Botucatu and 1980 in Piracicaba) to 1983, second period is from 1984 to 2008 and third period is from 2009 to 2012 or 2013. In the second period there was a tendency of reduction in the annual volume of rainfall. The occurrence of the three distinct periods are related to land use change in São Paulo State, to expansion of the agricultural frontier in the northern and middle-western Brazil and to increase in the practice of biomass burning. Keywods: trend test, linear regression, aerosols, climate change.

ABSTRACT: Introduction: Demonstrating the results of Social Distancing Strategies (SDS) became a relevant factor to obtain support by the population in São Paulo State and in Brazil. The delay in the processing of PCR tests and the small number of tests available limits the ability of sanitary authorities to make meaningful data available as to the number of cases or the number of deaths due to COVID-19. Methodology: We use a time series analysis of deaths due to COVID-19 referenced to the date of deaths (as opposed to the date in which the test results were obtained). Results: We demonstrate that the SDS adopted in São Paulo City and State clearly brought meaningful results to delay the growth of COVID-19 cases. We also show that by using this type of time series it is possible to identify different trends for regions, allowing for targeted approaches. Additionally, by using a time series which is death-oriented makes it possible to identify, for São Paulo City, the effects of the SDS with the Social Isolation Index (SII) adopted in the state and to make a gross estimate for the SII, which prevents the growth of the disease. Conclusion: The use of a time series of deaths due to COVID-19 referenced to the date of the event allows a better understanding of the effects of the SDS on the progression of the COVID-19 epidemic in São Paulo State, Brazil.

The urban population increase in the world, the economic expansion, and the rise in living standards associated with society’s habits and lifestyles accelerated the municipal solid waste (MSW) generation in undeveloped countries, such as in Brazil, in which the generation increased by 25% from 2012 to 2017. In the same period, the São Paulo state, the richest Brazilian state, increased its municipal solid waste generation by 51%. All this MSW needed to be collected and transported, and this process has a high economic and environmental cost. Therefore, this study aims to identify, using spatial analysis, the routes used by MSW trucks to estimate the distances traveled to dispose of the MSW on a regional scale considering all municipalities in the São Paulo state. The findings showed that the landfill numbers decrease, mainly individual ones, which receive MSW only from the city where it is located. Otherwise, the consortium landfills number is increasing, as well as the number of municipalities that share the same disposal site. Consequently, the distances to transport MSW from urban areas to final disposal sites increased by about 55% from 2012 to 2017, reaching 613 million kilometers during this period. This total distance is sufficient to make more than 12,806 laps on Earth and contribute to high fuel consumption and greenhouse gas emission.
