“…In this analysis, we used the daily precipitation from the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) [80], which has the advantage of incorporating 0.05 • resolution satellite imagery with in situ station data. The determination of the onset/demise dates and the length of the rainy season in the Amazon region and South America have already been investigated by different methods [7,77,78,[81][82][83][84][85]. However, the method used in our study was sufficient for our purpose.…”

“…O ciclo anual climatológico de precipitação em MG é bem definido, com inverno seco (Figuras 2a-2c) e verão chuvoso (Figuras 2g-2i), consistente à climatologia de precipitação do estado mostrada por Silva e Reboita (2014) e Reboita et al (2015),com períodos de transição na primavera e no outono (Figuras 2d-2l). Esses resultados são característicos do Sistema de Monção da América do Sul (SMAS) (RAO et al, 1996;ZHOU;LAU, 1998;GARCIA, 2016;GARCIA et al, 2016a;2016b).O ciclo sazonal da precipitação do SMAS tem início na Amazônia equatorial, propaga-se rapidamente para leste e sudeste no final de setembro e início de outubro, gerando uma estação úmida com chuvas abundantes na Bacia Amazônica. Na fase madura do SMAS (final de novembro até final de fevereiro), essa atividade convectiva da região amazônica estende a precipitação sobre o sudeste do Brasil e o oceano Atlântico adjacente, caracterizando uma banda de nebulosidade, a Zona de Convergência do Atlântico Sul (KODAMA, 1993).…”

No intuito de suprir as necessidades do consumo interno de azeite e azeitona, muitos produtores no Brasil, mais especificamente no sul de Minas Gerais, têm investido nesse cultivo. Entretanto, para viabilizar a expansão da olivicultura é necessário conhecer as condições climáticas limitantes ao seu cultivo, principalmente em relação a eventos extremos de temperatura e precipitação; que são os maiores limitantes à olivicultura. Por isso, o objetivo deste estudo é determinar as áreas climatologicamente aptas ao cultivo da oliveira, em Minas Gerais. Para isso, foram calculadas as climatologias mensais de precipitação e das temperaturas média, máxima e mínima do ar; para o período de 1981 a 2010, em 49 estações meteorológicas de Minas Gerais. Também foram calculados os percentis para determinação de eventos extremos de precipitação (P5 e P95), temperatura máxima (T90) e mínima (T10); além de contabilizar o número de casos com temperatura inferior a 9,5°C e superior a 30°C. Por fim, foi analisado a relação da quantidade dos eventos extremos com as fases fenológicas da oliveira. Os eventos de temperatura inferior a 9,5°C, ocorrem com maior frequência (≥1500 eventos) na região sul do estado. Com relação a eventos de temperatura superior a 30°C, há um maior número de casos (≥1000 eventos) no noroeste, norte, Vales do Jequitinhonha e Mucuri, Central e Triângulo Mineiro. Já a precipitação não inviabiliza o cultivo de oliveira em Minas Gerais, principalmente pela possibilidade de irrigação suplementar nas regiões com maiores registros de P5 e pelo pequeno número de casos (≤ 24 eventos) de P95. Somente as regiões sul e pequena parte do centro-oeste de Minas Gerais possuem características climáticas favoráveis ao cultivo de oliveira

“…The presence of total coliforms and E. coli in the water supply and distribution system persisted throughout the study months, and from July 2017 total coliform contamination was present in all samples analyzed. For E. coli, the highest frequencies of contamination were observed during the rainy season, between November and March (Santos and Garcia, 2016), especially in November/2017, January and February 2018, where percentage of contamination were 55.5%, 100.0% and 88.9%, respectively. The result is in agreement with the fact that there is a consensus that the worsening tendency of water quality in rainy periods is a consequence of the drag of organic matter and various particles, which protect the microorganisms from contact with chemical disinfectants, which favors its viability (Gleason and Fagliano, 2017).…”

Consumption of non-potable water is a relevant public health problem due to the possibility of transporting numerous chemical and microbiological contaminants. In 2005, the Brazilian Ministry of Health created the National Program of Surveillance in Environmental Health related to the Quality of Water for Human Consumption (VIGIAGUA), with the primary purpose of managing risks related to water supply to human populations in Brazilian territory. However, VIGIAGUA does not have a methodology capable of characterizing or managing risks. The objective of this research is to create a working model to transform raw data into conceptual data related to low-, medium- and high-risk levels. The data used in the application of the model were obtained through the analyses of water-quality surveillance conducted by the Regional Health Management of Itabira, a municipality with less than 10 thousand inhabitants, whose history of water contamination is alarming. Twelve samples/month were collected between May 2017 and April 2018. The results of the treated water analyses were classified according to the presence of hazards and categorized into risk levels. The results showed 83.3% contamination by total coliforms at the treatment plant and 91.6% in the distribution system. The Escherichia coli contamination was 16.7% in the treatment plant samples and 45.2% in the distribution system. The system was categorized as "High Risk". The analysis of untreated water samples was carried out for the purpose of knowing the contamination pattern of the raw water of the region, finding 100% contamination by total coliforms and 97.2% contamination by E. coli.
