A matrix of the food plants was created using a primary source ("Contribution to the study of the flora from Pernambuco, Brazil", by Dárdano de Andrade-Lima) and secondary sources of past use (centuries XVI/ XVII/ XIX), contemporary (50s-70s decades) and current (from the 70s decade) to the central work. This study has revealed the potential of the native food flora from caatinga and the importance of prioritizing the record of this information, which is proven, the number of research for nutritional analysis of these species is still limited.

The relative importance of 36 native woody species reported as being useful by 98 informants was calculated employing the Use-Value (UV) and Relative Importance (RI) techniques. Both techniques place value on a given taxon based on the number of uses attributed to it. Results obtained for both techniques are positively correlated, suggesting that they can be used interchangeably to evaluate local knowledge of a given resource. The implications and interpretation limitations of these two techniques are discussed in detail. We performed a rapid and simple evaluation of the Use-Value (UV) and Relative Importance (RI) quantitative

Poir. in three rural communities in the cities of Itaporanga, Lagoa and São Mamede (Paraíba, Brazil). Semi-structured interviews were conducted with all heads of families (men/women), in the communities of Pau D’Arco, Barroquinhas and Várzea Alegre. The interviews focused on the identification and analysis of the current and potential uses, to obtain more precise information about the relationship of the informants with M. tenuiflora. The uses were distributed into nine categories. In the communitites of Pau D’Arco in Itaporanga town, Lagoa in Barroquinhas and São Mamede in Várzea Alegre, 43, 181 and 158 use citations were identified, respectively. The separation of current and potential use is important for expressing the situation in terms of the conservation of species that are threatened by the multiplicities of uses. The greatest current use for M. tenuiflora, considering all us...

Specifically, the goal was to catalog local knowledge regarding the use of native and exotic forage plants in two rural communities located in the state of Paraíba (northeast Brazil), to provide information for nutritional investigations and to verify how the knowledge of these resources is distributed. Methods: The communities were followed for three consecutive years, and interviews were conducted with 44 families (20 men and 24 women). Nine of these individuals were determined by the snowball technique to be key informants who held more specific knowledge about the topic. The data were structured into a database and statistically analyzed. Results: Overall, 136 plants from 37 families and 113 genera were cited, and the knowledge of men was at a higher level than that of women (p < 0.05). Participants demonstrated a sophisticated knowledge of nutritional characteristics such as nutritional value, palatability, availability and productivity. Native plants were highlighted over the exotic, especially for species of the families Cactaceae, Bromeliaceae and Fabaceae. Conclusions: The great diversity of plants cited by the informants demonstrates the potential of local vegetation and the importance of traditional knowledge in the research process and in the characterization of forage resources. This diversity also favors the selection of promising species for future biotechnological investigations.

Brenan) by a rural community in northeastern Brazil was examined. By employing different techniques of data collection and population structure analysis, it was determined that this species had multiple uses within the local community (especially as timber and for other wood products), and that local management of this species is based on simple maintenance and harvesting of individuals in agroforest homegardens. The study of the population structure of this tree species indicated that management and conservation strategies must include the participation of the local community.

O trabalho foi conduzido a partir de entrevistas semi-estruturadas, associadas à técnica da turnê-guiada, realizada com os mantenedores dos quintais. Paralelamente, fez-se medição da área do quintal e de todos os indivíduos lenhosos com DNS (diâmetro ao nível do solo) > 3 cm. Registrou-se 25 quintais, nos quais foram relacionadas 84 espécies, pertencentes a 68 gêneros e 35 famílias, destacando-se as famílias Euphorbiaceae (10 spp.), Anacardiaceae (7 spp.), Caesalpiniaceae (6 spp.), Mimosaceae (6 spp.) e Myrtaceae (6 spp.). As espécies introduzidas (55 espécies) dominaram nos sistemas em relação às nativas. Apesar destas terem sido menos freqüentes nos quintais agroflorestais, elas são importantes para conservação da diversidade local devido, principalmente, ao uso madeirei...

Entretanto, na pratica, o que se constata em pouco tempo apos a implantacao de uma usina e que os beneficios sao poucos em relacao aos problemas gerados aos habitantes. Diante disso, essa pesquisa objetivou diagnosticar conflitos ambientais gerados pela usina eolica no municipio de Caetes (PE), para tal utilizou-se o Diagnostico Rapido Participativo junto a uma comunidade rural do municipio, atraves de visitas ao local seguida de uma oficina com as familias de agricultores da regiao. Como resultados, encontrou-se sinalizacoes ja percebidas em outros empreendimentos similares como os danos ambientais, como alteracao dos servicos ecossistemicos; problemas sociais provocados pela proximidade da usina as residencias, gerando poluicao sonora entre outros desconfortos e queda nas atividades agropecuarias. PALAVRAS-CHAVE: agricultura familiar, DRP, energia eolica.
