“…Rainfall shocks (Pereda et al 2014;Rabassa et al 2014;Rocha and Soares 2015), natural disasters (Simeonova 2011;Currie and Rosin-Slater 2013), and vector borne diseases (Barreca 2010), are all consequences of climate change and increasing temperature levels that have also been found to impair fetal health. Yet, there is no evidence suggesting that exposure to high temperatures during pregnancy affects the health condition in adulthood (Agüero 2014).…”

The discussion on the effects of climate change on human activity has primarily focused on how increasing temperature levels can impair human health. However, less attention has been paid to the effect of increased climate variability on health. We investigate how in utero exposure to temperature variability, measured as the fluctuations relative to the historical local temperature mean, affects birth outcomes in the Andean region. Our results suggest that exposure to a temperate one standard deviation relative to the municipality's long-term temperature mean during pregnancy reduces birth weight by 20 grams and increases the probability a child is born with low birth weight by 10 percent. We also explore potential channels driving our results and find some evidence that increased temperature variability can lead to a decrease in health care and increased food insecurity during pregnancy.

“…There is evidence that household income and maternal nutrition during pregnancy, especially in the last trimester, and the disease environment during pregnancy affect the incidence of low birthweight through IUGR (see for example Almond 2006, Almond and Mazumder, 2011, Amarante et al 2014, Rocha and Soares 2015. Smoking is also a significant predictor of low birthweight (Almond et al 2005).…”

This paper uses microdata from Brazilian natality and mortality vital statistics between 2000 and 2010 to estimate the impact of in-utero exposure to local violence -measured by homicide rates -on birth outcomes. The estimates shows that exposure to violence during the first trimester of pregnancy leads to a small but precisely estimated increase in the risk of low birthweight and prematurity. Effects are found in both rural areas, where homicides are rare, and in urban areas, where violence is endemic. Our estimates imply that homicides in Brazil are responsible for at least 0.5 percent of the incidence of low birthweight (<=2.5 kg) and 3 percent of the incidence of extremely low birthweight (<=1 kg).

Groundwater reserves in the semi-arid regions, which are mostly brackish, could be used to meet local water demands. Hydroponic cultivation is an alternative of rational use of water. Thus, the objective of this work was to evaluate the technical feasibility of using brackish groundwater in the semi-arid region of Bahia and Recôncavo of Bahia for hydroponic production of curly lettuce cv. 'Verônica' and purple lettuce cv. 'Quatro Estações'. The experiment was conducted in a greenhouse in the city of Cruz das Almas, Bahia State, in a randomized block experimental design, composed of seven treatments [T1-public-supply water; T2-water from the well of UFRB; T3-reject water from the well of Cruz das Almas; T4-water from the well of Sapeaçu; T5-reject water from the well of Sapeaçu; T6-reject water from the well of Conceição do Coité and T7-artificially salinated water (NaCl)] and six replicates in an experimental hydroponic structure using the nutrient film technique (NFT). The following variables were analyzed: number of leaves, shoot fresh matter, shoot length, root length, shoot dry matter, and root dry matter. Relative shoot dry matter production in curly lettuce increased by 1, 5, and 2% in the treatments T2, T3, and T4, respectively, whereas in purple lettuce, the increments were 10, 1, and 20%, respectively, for the same treatments. The use of brackish groundwater from the deep tubular wells of the Federal University of Recôncavo da Bahia and Sapeaçu and desalination reject water from the tubular well of Cruz das Almas proved to be technically feasible for hydroponic lettuce production.
