Abstract :
[en] In developing countries, studies on sustainable preservation of forests (including non-timber forest products NTFPs) have been poorly carried out for promoting alternative income generating activities (IGA) to alleviate pressure on praised resources by local communities living close by protected areas. This study aimed at (1) inventorying NTFPs exploited by local communities around the Kahuzi Biega National Park (KBNP), (2) assessing their therapeutic values and nutritional contributions, and (3) analyzing their rural and urban market values to determine their potential as alternative income sources as well as the major constraints in their exploitation. Individual interviews were conducted with 790 rural and urban households in Kabare, Walungu, Kalehe, and Bukavu City, eastern Democratic Republic of Congo (DRC) coupled with focus group discussions with key stakeholders around KBNP. Street vendors, restaurants, hotels, and market owners were also interviewed on uses, awareness of the nutritional and therapeutic values, and factors hindering NTFPs wide use in Bukavu urban environments. Physicochemical analyses were also conducted on main NTFPs to determine their nutritional values. Results showed that local populations around KBNP exploit at least 55 NTFPs, mainly for self-consumption as food, feed, and medicine. NTFPs represent the second most important income source around KBNP, accounting for 23.3 % of total households’ income after agriculture that generates 25.7 % of total households’ income. Income from NTFP trade was primarily used for food supply (29 %), investment in small businesses (19.6 %), children's education (17.7 %), and healthcare expenses (5.1 %). These NTFPs had varying nutritional values (in terms of proximate composition, essential minerals, and bioactive compounds). Solanum nigrum (24.9 %), Termitomyces robustus (18.0 %), Amaranthus viridis (17.6 %), and Piper nigrum (16.9 %) are valuable sources of proteins while Zingiber officinale (25.5 %), T. robustus (15.4 %) and P. nigrum (14.3 %) are rich in dietary fibres. Piper nigrum (37.0 and 128.3 mg/kg) and Basella alba (35.1 and 108.7 mg/kg) had the highest zinc and iron contents, respectively. Some of the most nutritious NTFPs, such as S. nigrum, Dioscorea spp., and P. nigrum had high contents in anti-nutritional elements and should be processed properly to maximize bioavailability. Besides, NTFPs created employment opportunities for collectors, vendors, supermarkets, hotels, and restaurants both in rural and urban areas. Though varying with rural communities, the main challenges in the NTFP value chain were low market values (48.6 %), short shelf life (22.5 %), and excessive taxation (19.1 %) while in urban areas, seasonality (36.9 %), scarcity (17.7 %), and prohibiting high prices (17.7 %) were the major limiting factors. This study highlights the significant role played by NTFPs in providing healthy and nutritious food and income for households surrounding the KBNP, and thus emphasizes the necessity for their promotion as alternative income sources and healthy diets to alleviate poverty and hidden hunger around the KBNP.
