Contributions of the old urban homegardens for food production and consumption in Rio Claro, Southeastern Brazil

Urban homegardens are green areas of households within the city limits and they have the potential to provide families with a cheap alternative for diet improvement, and to complement the income of the families who sell cultivated products. This research analyzes the contributions of old urban homegardens on food consumption and household economy. Data related to homegardens composition were collected by interviews and by collecting cultivated plants. Diets were assessed through a retrospective method (last 24 hours food recall) and administered every two months, during a year, to include seasonal variations. The diet of the sampled population was found to be dependent on certain foods, indicating a narrow food niche (Levins index = 25.9; Levins standardized index = 0.23). Variations in interviewees' diet are related to the consumption of fruits and vegetables, which are partly supplied by homegardens. Spices and teas consumed were obtained from homegardens, revealing its importance in food consumption and health. Among the 98 species found in homegardens, only 38% appeared in the interviewees' diet, indicating an under-exploitation of these homegardens. Our study found that the main role of homegardens is to supply variation in the diet, contributing to the consumption of different types of products.

Atividade diurética dos extratos aquoso e etanólico de Bugre (Hedyosmum brasiliense Miq.) e seus efeitos na pressão arterial média em testes pré-clÍnicos

The object of this study was assess through pre-clinical tests, the possible diuretic activity and the effects on the mean arterial pressure of the aqueous and ethanolic extracts of branches of “bugre”, Hedyosmum brasiliense Miq., species used in the treatment of renal and urinary disorders The tests were made in males anesthetized Wistar rats and randomly distributed into 4 experimental groups: Group I – Water control, group II – treated with aqueous extract (EA) of “bugre”, Group III – water control + “tween 80”, group IV – treated with ethanol extract (EE) and “bugre”. All groups were subjected to experimental protocol, composed of three periods: Balance (40 minutes), Basal (30 minutes) and Experimental (90 minutes), occurring the urine collection every 30 minutes, from the basal period and measuring blood pressure every 10 minutes. The results presented validate the ethnobotany indication of the use of H. brasiliense tea in the treatment of renal problems, because increased significantly the urinary flow in anesthetized Wistar rats (diuretic effect), without changing significantly (p>0,05) the arterial pressure

Plantas tóxicas do município de Cananéia: um enfoque etnobotânico

Among several sites in Brazil, where the local human community develop a consistent knowledge on the environment they live, there is Cananeia local authority in south coast of Sao Paulo. The history of Cananeia is presented as an ancient human occupation, which, nowadays, culminates in 12000 habitants that survive from tourism and fishing. Considering the great importance of the knowledge about plant toxicity, the objective of this work is to develop a study with the residents and its focus is their acquaintance with toxic plants, which occur on contiguous areas. After a preliminary recognition field work, the local authority under study was subdivided into two areas for sampling, characterized by the different levels of human occupation: (A) Island area, more occupied, and (B) Continental area, less occupied. The semi-structured interviews were conducted in both areas according to the “snow ball” method, due to the specifically interest of making comparisons. The plant species cited in the interviews were collected, herborized and identified. One proceeded quali- and quantitative analysis in order to elucidate differences between the studied areas, to establish relations among age/sex of the habitants, the cited species diversity and the practice of knowledge transmission. Were carried out 90 interviews (47 in island, 43 in continent) in which the habitants have cited 137 ethno-species. Both communities are much alike, although the manly differences were presented by the occupation and the uses of the toxic plants. At the island, were interviewed three key-informers, this fact that has not happened at the continent. It was not noticed significant statistical difference between the diversity of toxic plants knew by the habitants of both areas, but a huge dissimilarity was found. The most cited plants, especially the ornamental ones, at both areas are scientifically... (Complete abstract click electronic access below)

Plantas ornamentais em quintais urbanos de Rio Branco, Brasil

Ornamental plants are important in the culture and welfare of city dwellers in the Amazon. This study aimed to perform a characterization of species of ornamental use in urban backyards of Rio Branco and relation with social aspects of the respondents. Semi-structured interviews featuring ornamental species along with analysis of social aspects of urban respondents of the 132 backyards in Rio Branco, Acre, Amazon between 2009 and 2011. Selected for this study were neighborhoods Aeroporto Velho, Placas and Novo Horizonte, located on the periphery of the municipality. Were detected 140 ornamental species belonging to 49 different botanical families, especially Euphorbiaceae (7%), Arecaceae (6.4%) and Araceae (5%). Ornamental species recorded, 57.5% are exotic, 16% have medicinal use and 44% herbaceous. Regression analysis of data across the diversity of species, area and social parameters of the respondents was not significant. The cultivation of ornamental plants in urban backyards Rio Branco assists in the ambience of the residence, landscape improvement, generates welfare for residents at leisure space beyond the conservation of genetic resources.

Impactos da legislação na pesquisa etnobotânica no Brasil, com ênfase na região amazônica

The Amazon region has a large sociobiodiversity, where lives people with traditional knowledge about the uses of its natural resources. The Convention on Biological Diversity (CBD) in 1992 recognized the autonomy of each nation over its genetic resources and the rights of traditional populations about the knowledge of the use of these natural resources. In 2001 it was published the law M.P. 2.186-16/2001 which created the Conselho Nacional de Gestão do Patrimônio Genético (CGEN) and the first rules about access to genetic resources and associated traditional knowledge in Brazil. Since his creation, the actions of CGEN have received criticism from various sectors, both private and public, and, unlike its initial proposal, has become one of the main obstacles of ethnobotanical studies, the bureaucracy, the long process analysis and communication difficulties with this organ.
