The objective of this work was to investigate the relationship between soil water content and rainfall with rice, beans, cassava and corn yields in the semiarid region of Northeast Brazil. Precipitation and modeled soil water content were compared to yields recorded at the county levels in this region. The results were also integrated over the area of the nine States that lie within the officially recognized region of semiarid climate in Brazil. The influence of water balance components was quantified by calculating their correlation coefficient with yields of the different crop species over the municipalities of the region. It was found that rainfall had higher correlation to crop yields over most of the region, while soil water content had lower values of correlation. This result is consistent with the fact that average root depth is 40 cm, lower than the layer of soil used in the model used to estimate soil water content (100 cm). Plants respond better to the precipitation in the top layers of soil, while the water storage in the deep layer of soil might be important only in other temporal and spatial scales of the hydrological cycle.

Resumo Este artigo integra a edição comemorativa dos dez anos da criação do Programa de Pós-Graduação em História da Universidade do Estado de Santa Catarina (PPGH/UDESC), ocorrido em 2007, e que se fez acompanhar, desde 2009, da Revista Tempo & Argumento. Tem como objetivo: apresentar as escolhas teóricas que balizaram a proposição do programa, com enfoque em História do Tempo Presente; identificar os recortes temporais e geográficos selecionados; as opções metodológicas e os enfoques teóricos privilegiados das dissertações de mestrado defendidas no decorrer deste período. Busca analisar as produções acadêmicas discentes como veículos de disseminação de estudos e debates sob a perspectiva da História do Tempo Presente, um campo em construção na área da História e que tem, na UDESC, o primeiro programa de pós-graduação específico com esta proposição temática. Palavras-chave: História do Tempo Presente. Universidade do Estado de Santa Catarina. Programa de Pós-graduação em História. Estudantes de Pós-graduação.

Soil moisture is a main factor for the study of drought impacts on vegetation. Drought is a regional phenomenon and affects the food security more than any other natural disaster. Currently, the monitoring of different types of drought is based on indexes that standardize in temporal and regional level allowing, thus, comparison of water conditions in different areas. Therefore, in order to assess the impact of soil moisture during periods of drought, drought Palmer Severity Index was estimated for the entire region of the territory. For this were used meteorological data (rainfall and evapotranspiration) and soil (field capacity, permanent wilting point and water storage in the soil). The data field capacity and wilting point were obtained from the physical properties of soil; while the water storage in soil was calculated considering the water balance model. The results of the PSDI were evaluated during the years 2000 to 2015, which correspond to periods with and without occurrence of drought. In order to assess the future drought projections, considering the set of the Coupled Model Intercomparison rainfall data Project Phase 5 (CMIP5). Climate projections precipitation in CMIP5 for the period 2071-2100 was extracted generating entitled forcing scenarios Representative Concentration Pathways - RCPs, and referred to as RCOP 8.5, corresponding to an approximate radiative forcing the end the twenty-first century of 8.5 Wm -2 . The results showed that the PDSI is directly associated with climatological patterns of precipitation and soil moisture in any spatial and temporal scale (including future projections). Therefore, it is concluded that the PDSI is an important index to assess soil moisture different water conditions, as well as the association with economic and social information to create risk maps for subsidies to decision makers.

Resumo O objetivo deste artigo é problematizar as possibilidades e dificuldades de discussões ancoradas pela categoria gênero em aulas de história na Educação Básica. Para tanto, elencamos uma série de atividades produzidas e ministradas por bolsistas do Pibid cujo tema versava sobre gênero e história das mulheres. A partir dos relatos produzidos pelos bolsistas, referentes às suas experiências com turmas de 9o. ano, refletimos sobre os recortes de conteúdo trabalhados, sobre a receptividade e resistências das turmas no que concerne à proposta em questão e, finalmente, sobre a percepção e significados atribuídos às questões de gênero na trajetória dos próprios bolsistas de iniciação à docência. Para esta análise, nos apoiamos em debates acerca da categoria de gênero, em saberes concernentes à formação docente e no conceito de experiência.
