Distribuição Temporal E Espacial Da Malária No Amazonas, De 2003 a 2019
The study aims to know the evolution of the malaria incidence in the municipalities of the state of Amazonas, during the period from 2003 to 2019, as well as to analyze the existence of seasonality of the disease. Using Pettitt's statistical test, changes in the pattern of malaria distribution were found, especially after 2011. On average, high values of malaria incidence were observed until 2010/2011, reaching, in some municipalities, a monthly …
Spatiotemporal Dynamics of Suspended Sediments in the Negro River, Amazon Basin, from In Situ and Sentinel-2 Remote Sensing Data
Monitoring suspended sediments through remote sensing data in black-water rivers is a challenge. Herein, remote sensing reflectance (Rrs) from in situ measurements and Sentinel-2 Multi-Spectral Instrument (MSI) images were used to estimate the suspended sediment concentration (SSC) in the largest black-water river of the Amazon basin. The Negro River exhibits extremely low Rrs values ( 7 m−1) caused by the high amount of dissolved organic carbon …
Detecting vulnerability of humid tropical forests to multiple stressors
Evolution of the riverine nutrient export to the Tropical Atlantic over the last 15 years
The Tropical Atlantic is facing a massive proliferation of Sargassum since 2011, with severe environmental and socioeconomic impacts. As a contribution to this proliferation, an increase in nutrient inputs from the tropical rivers, in response to climate and land use changes or increasing urbanization, has been often suggested and widely reported in the scientific and public literature. Here we discuss whether changes in river nutrient inputs cou…
L’enseignement des sciences et de l’agriculture dans les écoles normales d’instituteurs de l’académie de Montpellier (1880-1905)
Cet article s’intéresse à l’enseignement des sciences et de l’agriculture dans les écoles normales d’instituteurs de l’académie de Montpellier, entre la promulgation des lois Ferry au début des années 1880 et la remise à plat de la formation des maîtres lors de la réforme de 1905. Il permet d’avancer que l’évolution des normes concernant l’enseignement de l’agriculture est allée de pair avec la place que les républicains accordèrent à l’étude gén…
From drought to flooding
In this work we document and analyze the hydrological annual cycles characterized by a rapid transition between low and high flows in the Amazonas River (Peruvian Amazon) and we show how these events, which may impact vulnerable riverside residents, are related to regional climate variability. Our analysis is based on comprehensive discharge, rainfall and average suspended sediment data sets. Particular attention is paid to the 2010–11 hydrologic…
