“…The green water footprint has the greatest influence, as it constitutes 86% of the total water footprint, the blue water footprint represents 12.5% and the gray water footprint is equivalent to 1.5% of the total water footprint for family farming. High values of the green water footprint were also observed in the works of Lacerda (2015), Costa et al (2016) and Pinto & Barbosa (2017). However, in studies by Lira et al (2014) in the agricultural sector in Chile, found a blue water footprint with greater representativeness than the other components of the total water footprint, thus the authors concluded that this fact can be explained due to the fact that the studied region has low average rainfall.…”

“…Vale destacar, mesmo que os cultivos de soja tenham sido irrigados em Maringá, os valores elevados de PHcinza (420 m³ t -1 ), contribuíram para evidenciar que houve redução na eficiência do uso de água nos cultivos de soja. Na China, a PHtotal da soja foi de 1.816 m³ t -1 (Huang et al, 2012), diferente dos valores encontrados por Costa et al (2016), também no Pará, mas no polo de grãos Paragominas, com valores da ordem de 1.327 m³ t -1 , os quais foram inferiores aos valores médios globais para a soja (2.144 m³ t -1 ), apresentados por Mekonnen e Hoekstra (2010).…”

“…A descoberta do princípio ativo pilocarpina das folhas do jaborandi foi efetuada simultaneamente, em 1876, na França por E. Hardy e na Inglaterra, por A.W. Gerrard (SILVA et al, 2013;HOMMA, 2003b;COSTA et al, 2016).…”

“…Iniciando a apresentação das metodologias para cada PH, temse a PH verde que consiste na quantidade de água da chuva que não escoa, ou seja, a água precipitada que fica retida no solo e é absorvida pelas plantas (HOEKSTRA et al, 2011). Nesse sentido, para este cálculo, faz-se necessária a instalação de equipamentos e sensores térmico-hídricos com o fito de obter dados acerca da quantidade de água precipitada, dos aspectos térmicos e da umidade relativa do ar em determinada unidade experimental (COSTA et al, 2016).…”
