Abstract

A study of the relationship between man and his environment was carried out in Brazzaville, Republic of Congo in the peri-urban forest of Djoumouna. Socio-economic and ethnobotanical surveys conducted among the human populations in riparian areas were supported by direct field observations and a review of the literature. Data were collected from a 2 km zone of influence around the Djoumouna forest. The group of survey participants, organized into four age groups, included all socio-professional categories and was made up of 143 heads of household. The survey participants were of both genders and ranged in age from 15 to over 45 years old. Ethnobotanical indicators were used as data analysis tools, specifically, ethnobotanical use-value, survey participant consensus factor, and level of fidelity. This study identified 13 plant species and more than 14 animal taxa as Non-Timber Forest Products (NTFPs) of animal and plant origin. Most of the taxa listed are used in traditional foods and/or phytotherapy. The low values of some ethnobotanical indicators show that these NTFPs, which are not highly sought after and valued by the population, are also rare in this peri-urban ecosystem. This observation is also valid when considering the involvement of survey participants by age group. However, the survey participant consensus factor reflects a unanimity of traditional exploitation of these NTFPs within the society. The analysis of the ethnobotanical data clearly show a difference in the level of exploitation of NTFPs between genders with men having more interest in finding and using NTFPs. Finally, the study indicates (i) gender specialization is associated with NTFP activities and exploitation, and (ii) a progressive erosion of traditional knowledge is occurring between age groups.
