This study assessed differences on the uses and transmission of traditional knowledge (TK) about three traditional leafy vegetables (Crassocephalum crepidioides (Juss. ex Jacq.) S. Moor, Launaea taraxacifolia (Willd.) Amin ex C. Jeffrey, and Vernonia amygdalina Del.) of the Asteraceae family over two generations in three villages: Adjohoun, Dangbo, and Pobè (southern Benin). Individual semi-structured ethnobotanical interviews of 360 respondents were conducted in the villages with young girls, boys, and their two parents. The relative frequency of citation, use value, and Jaccard similarity index were used for data analyses. Vernonia amygdalina was the most commonly known and used vegetable in all villages, while L. taraxacifolia was confined to Pobè. Factors such as village of survey, generation, and gender affected the use value of the species, but the patterns of recognition and cultivation were species-specific. Leaves were the most used plant part. Traditional knowledge was largely acquired from parents (90% of citation), and both mothers and fathers transmitted a similar amount of knowledge to their progenies. The knowledge on V. amygdalina was transmitted to a larger scale than knowledge of C. crepidioides and L. taraxacifolia. Irrespective of the species, transmission of TK was higher in Pobè. Gender and generation knowledge dynamic hypothesis is species-specific. TK transmission was species-specific too and may be linked to the local importance and use of those resources. These findings will inform strategies and programs for the sustainable use and conservation of leafy vegetables in local communities and national research and development institutions.

Agroforestry Practices

(Author of this paper, S Khanal was omitted in error - added on 29-3-2010)Leasehold forestry in Nepal has sought to address both poverty alleviation and environmental conservation. The major agroforestry practices observed in the leasehold forests were silvopasture, hortisilviculture and Non Timber Forest Product (NTFP) cultivation. The most prominent problem to the users in adopting agroforestry practices was the lack of technical information. Some successful insights observed suggest that agroforestry has a notable potential to address dual objectives of poverty alleviation and conservation. The need to evolve sustainable mechanism for promoting agrofrorestry in degraded lands through the dissemination of useful traditional knowledge, innovative practices and improved technologies was identified.

Males And Females

This study examined the traditional knowledge of fishermen at Mamirauá Reserve about sex determination of pirarucus, Arapaima gigas Schinz 1822. We evaluated the criteria used for by fishermen in the sector Jarauá at Mamirauá Reserve for this determination, during the fisheries season, from October to November 2004. We analyzed responses of a group of about 15 fishermen collected in structured interviews regarding 109 individual pirarucus, 65 males and 44 females. From this sample, only 64 fish have their sex correctly predicted by the fishermen. Although the traditional knowledge of local fishermen is a key component of the sustainable fisheries of this species, this knowledge is not functional in all ranges and aspects, as in sex distinction. We found that the local fishermen evaluated are not able to recognize the sex of pirarucus, although some criteria applied for this purpose are consistent with their biology. The rates of correct forecasts for recognition of males and females were similar to those obtained by chance, even when the criteria applied were consistent, as the criterion “coloration”, which was significantly consistent for identification of males. Yet the group of fishermen interviewed in this study apparently did not apply this criterion correctly.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.
