This study was carried out to examine women’s participation in livestock raising in rural communities of Nafada, semi-arid region of Northeastern Nigeria. Thirteen villages were purposively sampled, and 10 women respondents were randomly selected from each village. Standardized interview schedule was adopted in the collection of information from the sampled respondents and analyzed using descriptive statistics and Pearson Product Moment Correlation. The results disclosed that approximately half (45%) of the respondents raised goats and sheep and 100% were involved regularly in cleaning of animal sheds, watering and grazing of animals. In addition, washing of clothes, food preparation, cleaning of the house, looking after all family members, child/family health care, preparing beverages and cleaning up after meals ranked highest among household activities undertaken by women. Major challenges of livestock raising, and household management were low innovation (ranked 1), rustling (ranked 2), ranching (ranked 2) and health of animals (ranked 2). Others included child/family care (ranked 1), food (ranked 1), fuel wood collection (ranked 3) and absence of funding from government agents. The correlation results revealed that family size and education of respondents were significant factors influencing the extent of women’s participation in livestock raising in the study area. Therefore, carefully targeted women-focused programmes on livestock farming, intensive adult education and improved agricultural extension/ veterinary services among others are crucial to improving women’s participation in livestock production in Nafada LGA.

This research sought to contribute to plant ethnotaxonomic studies and aimed to describe cognitive and utilitarian aspects used in communities in the semi-arid region of Brazil. The question asked in the interview was: "What plants do you know?" The interviews were conducted with local specialists, using plant names written on cards randomly placed on a table. The informants were asked to organize the cards according to their understanding. Two hundred and one folk generics were recorded in Cachoeira and 185 in Barrocas, both communities located in the Municipality of Soledade (Paraíba). These generics were divided into 65 trees/shrubs, 138 herbs, 10 lianas/creepers, 7 cacti, and 4 bromeliads. A total of 146 monotypic and 24 polytypic folk generic were identified. The life forms were abundant; some of them had already been recorded in the literature but others were recorded for the first time. The morphological and utilitarian aspects were the most used classification criteria. The informants followed no consensus model to organize their classification.

Animal Consumption

Diante da histórica escassez de recursos hídricos na região semiárida, é notória a necessidade de se encontrar novas fontes de obtenção e armazenamento de água, seja para o consumo humano e animal ou para produção agrícola. A implantação de barragens subterrâneas no semiárido brasileiro pode contribuir de forma positiva na melhoria do abastecimento humano em comunidades rurais, além do fornecimento de água para o consumo animal e para produção de alimentos. Como sua construção se dá sobre os solos aluviais, o presente estudo tem como objetivo avaliar o potencial de aproveitamento desses solos no estado de Pernambuco para a implantação de barragens subterrâneas e verificar as áreas passíveis de salinização para a escolha adequada desse tipo de intervenção. A área de estudo corresponde ao estado de Pernambuco, em que a presença de solos aluviais foi observada por bacia hidrográfica, utilizando os dados do Zoneamento Agroecológico do Estado de Pernambuco (ZAPE). Com a mesma base de dados foram selecionados os solos com características salinas e estimada, por aluvião, a capacidade de armazenamento de água. Foi possível verificar que o estado de Pernambuco apresenta consideráveis áreas de solos aluviais, com potencial para aproveitamento das águas subterrâneas e para construção de barragens subterrâneas, bem como identificar as regiões onde a implantação desse tipo de obra deve ser mais restritiva por conta do risco de salinização.  Evaluation of the Alluvial Use Potential for a Construction of Underground Dams in the Semi-Arid Region of PernambucoA B S T R A C TGiven the historical scarcity of water resources in the semi-arid region, it is clear the need to find new sources for obtaining and storing water, either for human and animal consumption or for agricultural production. The establishment of underground dams in the Brazilian semi-arid region can contribute positively to the improvement of human supply in rural communities, as well as the supply of water for animal consumption and food production. As its construction takes place on alluvial soils, the present study aims to evaluate the potential use of alluvial soils in the state of Pernambuco for the implantation of underground dams and to verify the salinization areas for the appropriate choice of this type of intervention. The study area corresponds to the state of Pernambuco, where the presence of alluvial soils was observed by watershed, using data from Pernambuco State Agroecological Zoning (ZAPE).  With the same database were selected soils with saline characteristics and estimated, in each alluvium, water storage capacity. It was possible to verify that the state of Pernambuco has areas considerable of alluvial soils, with potential for groundwater utilization and for the construction of underground dams, as well as to identify the regions where the implementation of this type of work should be more restrictive due to the risk of salinization.Keywords: groundwater, alluvium, subsurface dam, risk of salinization.

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.
