Suscetibilidade da Bacia do Rio Bengalas a deslizamentos de terra
Landslides have frequently occurred in last years, due to the disorderly
grownth of the cities and the occupation of risk areas by the poor population, causing social,
environmental and economic impacts. Urban areas in expansion move to geologically
unstable areas and topographically inclined, such as the Basin of River Bengalas, located in
the city of Nova Friburgo, mountainous region of the State of Rio de Janeiro, Brazil. This
article aims to present the model survey to assess the susceptibility of the Basin of River
Bengalas to landslides, which in january 2011, with the occurrence of heavy rains, caused
landslides that impacted in the death of 429 people in city of Nova Friburgo. For the case
study, several investigations have been made related to the areas of the basin, such as slope,
soil conditions, lithology, land use and cover, vertical and horizontal curvatures. With this
study it was possible to understand how the natural and anthropics elements of the basin are
related to the local dynamics of the disasters regarding to their interferences in the induction
of landslides, thus enabling improved public management of the Municipality regarding the
use and division of land, from the identification of areas Basin of River Bengalas susceptible

Latin American consumption of major food groups: Results from the ELANS study
Background
The Latin American (LA) region is still facing an ongoing epidemiological transition and shows a complex public health scenario regarding non-communicable diseases (NCDs). A healthy diet and consumption of specific food groups may decrease the risk of NCDs, however there is a lack of dietary intake data in LA countries.
Objective
Provide updated data on the dietary intake of key science-based selected food groups related to NCDs risk in LA countries.
Design
ELANS (Latin American Study of Nutrition and Health) is a multicenter cross-sectional study assessing food consumption from an urban sample between15 to 65 years old from 8 LA countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela). Two 24-HR were obtained from 9, 218 individuals. The daily intake of 10 food groups related to NCDs risk (fruits; vegetables; legumes/beans; nuts and seeds; whole grains products; fish and seafood; yogurt; red meat; processed meats; sugar-sweetened beverages (ready-to-drink and homemade)) were assessed and compared to global recommendations. Results Only 7.2% of the overall sample reached WHO's recommendation for fruits and vegetables consumption (400 grams per day). Regarding the dietary patterns related to a reduced risk of NCDs, among the overall sample legumes and fruits were the food groups with closer intake to the recommendation, although much lower than expected (13.1% and 11.5%, respectively). Less than 3.5% of the sample met the optimal consumption level of vegetables, nuts, whole grains, fish and yogurt. Largest country-dependent differences in average daily consumption were found for legumes, nuts, fish, and yogurt. Mean consumption of SSB showed large differences between countries.
Conclusion
Diet intake quality is deficient for nutrient-dense food groups, suggesting a higher risk for NCDs in the urban LA region in upcoming decades. These data provide relevant and up-to-date information to take urgent public health actions to improve consumption of critically foods in order to prevent NCDs. Copyright
