A região do Alto Sertão localiza-se no extremo oeste do estado da Paraíba e, por estar localizada no Semiárido brasileiro, possui um regime anual caracterizado com chuvas escassas e irregulares. Contudo, existem registros de desastres hidrometereológicos na região de estudo. Objetiva-se por este trabalho analisar a distribuição espaço-temporal das ocorrências de desastres naturais de ordem hidrometereológica na região do Alto Sertão da Paraíba aos quais almejaram decretos por Situação de Emergência (SE) entre os anos de 2004 e 2009. A respeito dos resultados, observou-se a ocorrência de 65 desastres hidrometereológicos sendo 34 ocorrências do tipo inundação; 14 ocorrências do tipo enxurradas; 12 ocorrências do tipo chuvas intensas; e uma ocorrência do tipo vendaval.Palavras-chave: Semiárido paraibano.

Due to the irregular rains corroborated by extreme rainfall that permeates this region, the Brazilian Northeast is susceptible to hydrometeorological disasters even though it is situated in the semi-arid region where there are few rains during the year. The objective of this article is to analyze the spatial and temporal distribution of the disasters caused by drought, which aimed at decrees by Emergency Situation (ES) and by State of Public Calamity (SPC), between the years of 2003 and 2016, in the region of Alto Sertão da Paraíba. The data of these disasters were found in the site of National System of Civil Protection of Ministry of Integration (MI).Keywords: Paraibano semi-arid. Natural Disasters.

ABSTRACT Intercropping systems of beet and green cowpea are beginning to be implemented in the northeastern semi-arid region in Brazil. The great challenge is to know if there is agro-economic efficiency in these systems when fertilized with organic matter produced by spontaneous species of the Caatinga biome. Thus, the objective of this research was to evaluate the effect of green manuring using different amounts of hairy woodrose (Merremia aegyptia) in the association of beet with green cowpea under the semi-arid conditions. The experiment was carried out at the Rafael Fernandes Experimental Farm, rural area of Mossoró, RN, Brazil, in the period of September-December 2015, in a randomized complete block design with four treatments and five replicates. The treatments consisted of hairy woodrose amounts incorporated into the soil (10, 25, 40, 55 t ha-1 on a dry basis). The cultivars of beet and green cowpea planted were ‘Early Wonder’ and ‘BRS Itaim’, recommended for the semi-arid conditions of the Brazilian Northeast. The best agro-economic performance for intercropping system of beet and green cowpea was obtained with 55 t ha-1 of hairy woodrose incorporated in the soil. The use of the hairy woodrose species as green manure is agronomically viable in intercropped systems with beet and green cowpea.

Uma das formas mais simples e aplicadas para a verificação da Tendência a Desertificação (TD) é através dos Índices de Aridez (IA). Assim, com a possibilidade de verificação da situação do IA e da TD na Região Semiárida do Nordeste, o objetivo foi a investigação da variação do IA e suas classificações, ao longo do período de 1961 a 2015 (em séries temporais de 30 anos), além TD para a região alvo do estudo. É maioria unânime que está ocorrendo a redução do IA para a região semiárida do Nordeste, sendo que cada estado apresenta uma situação peculiar e possível justificativa para o que está ocorrendo. Apesar de mudanças do IA, em muitas localidades, observou-se que não ocorreu alterações na classificação a Tendência a Desertificação, porém apresentam a maior tendência desertificação e a sua é classificação é alta. Verificou-se que também é necessário o aprofundamento deste estudo, com mais variáveis e com o uso da modelagem numérica e de tendência no que diz respeito à avaliação da desertificação para algumas regiões que foram pouco conclusivas do Semiárido do Nordeste.  A B S T R A C TOne of the most useful and applied forms for verification of the Desertification Trend (TD) is through the calculation of the Aridity Indices (IA). Thus, the present work uses such methodology to verify the situation of IA and TD in the semi-arid region of Northeast Brazil. The objective was to investigate the variation of AI and its classifications over the period from 1961 to 2015, using a time series of 30 years, in addition to TD for the target region of the study. It is a consensus in the literature the occurrence of IA reduction for the semi-arid region of the Northeast, with each state presenting a peculiar situation and possible justification for the occurrence. With the results was possible to observe that in spite of changes of the IA in many localities, it was observed that there were no changes in the classification of the Tendency to Desertification. It was also verified the need to deepen these studies using climatic variables, with the use of more variables and with the use of numerical and trend modeling with regard to the evaluation of desertification for some regions that were not conclusive in this study.Keywords: Climate change, moving averages, climatology.

Background:: Luffa cylindrica is a plant that is widely distributed in Africa and Asia and it can be grown in regions with tropical or subtropical climates. Few patents dealt with Loofah biological properties, including some functional foods formulated from its leaves. Objective:: This study aimed to structurally and functionally characterize the bioactive compounds of L. cylindrica leaves grown in two different environments. Methods:: The extracts of L. cylindrica leaves collected from two Tunisian locations: Essouasi (LE), a semi-arid region and Medenine (LM) an arid region, were investigated for their phenolic compounds and fatty acids using HPLC/TOF-MS and GCMS techniques respectively. Furthermore, the antioxidant capacity was evaluated with DPPH, Chelating effect, Hydroxyl radical and Superoxide anion scavenging activities while the anticancer activity against HeLa cell lines was assessed using xCELLigence real time cell analyzer and lactate dehydrogenase cytotoxicity assay. Results:: The antiproliferative capacity of both extracts was time and dose-dependent with LE presenting the lowest HeLa cell index (CI = 0.035 ± 0.018, 250 μg/ml). LE also showed the best cytotoxic capacity (56.49 ± 0.8%) and antioxidant potential (IC50 = 54.41 ± 1.12 μg/ml for DPPH and 12.12 ± 0.07 μg/ml for chelating effet). 14 phenolic compounds were detected in LE with ferulic acid being the major compound (5128.5 ± 4.09 μg Phenols/g) while LM had only 6 phenolics. GCMS analysis showed the presence of omega-3 fatty acids in LE. Conclusions:: Our findings suggest that L. cylindrica leaves, especially when collected from semi-arid regions, are promising for formulating nutraceuticals of interest.
