Book (stand-alone)Multipurpose tree production systems
Joint IUFRO P.1.09-00 and International Poplar Commission, FAO, Ad-hoc Committee on Biomass Production Systems Workshop, Beijing, China, Sept 5-7, 1988
1989Also available in:
No results found.This workshop on Multipurpose Tree Production System of IUFRO P.1.09.00 "Integrated Research in Biomass for Energy" and IPC/FAO Ad-hoc CommitY:ee on Biomass Production Systems in Salicaceae" was organ:_zed around the themes of biodiversity, sustainability and economic development. A total of 2:1 papers were presented and 66 participants from 14 different countries attended. The Chinese delegation representing a large number of Universities and Government agencies from across China was very significant, as was that of the African countries (Zanbia, Tanzania, Kenya and Ethiopia) supported by SIDA and guided by the Swedish delegation to a post-workshop study tour to view projects on soil erosion control. The presentations covered case studies and overviews of a wide range of industralized and developing countries.The topic of the first session included the selection of species and production systems for different economical and environmental conditions and pu rposes. In the second session the presentations focused on the need to consider long-term sustainability of the ecosystem when used for husbandry or when cultivated. The third and last session complemented the previous two by considering the "Socioeconomic aspects", of biological production systems such as their role in the social and economical patterns of the societies concerned. The approach to reforestation has so far been oriented primarily towards economical profit. The res tricted aareness and knowledge of natural resource management led to the complete destruction of many ecosystems or the replacement of natural forests by monocultures. Although production systems may vary considerably, from intensively cultivated wocdgrass lots to extensively managed agro-forestry, one of the major concerns must be to establish a system that is sustaiPable and of complementary nature for both the ecological and the economical point of view. -
Book (stand-alone)Indigenous Knowledge of Edible Tree Products - The Mungomu Tree in Central Mozambique 2005
Also available in:
No results found.The objective of the study was to review and document the local knowledge base on the Mungomu tree in the district of Macossa and establish whether it varies according to gender, socio-economic status and generational differences. The study also looks at how the nut is used by local people and at its importance for food security. The study found that the culture of using Mungomu is very much alive in the district of Macossa. All long-term residents knew about the Mungomu tree and its n ut Ngomu, and only a few new residents who arrived after the civil war were not aware of it. Consumption however is declining due to the use of oilseeds such as peanuts, and the amount of work involved in cracking the nuts. Traditional methods involve using a small and a big stone to crush the nut, or splitting the nut casing with a stick and an axe blade. These rudimentary systems for cracking the nut were found to be the main barrier to maintaining, or possibly commercializing, the utilization of Ngomu. The kernel is used to enrich sauces, to accompany meat, fish, and vegetables, but also to produce oil. Consumption increases in difficult times, such as droughts and during the civil war. -
ArticleEthnobotanical survey of less-known indigenous edible tree Diospyros mespiliformis (Ebenaceae) in Benin, West Africa
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.African ebony (Diospyros mespiliformis) is a priority indigenous fruit tree that has several uses but its use pattern and conservation are little documented across various ethnic groups in Benin. These surveys carried out in 2018 aimed at provide a critical appraisal of the existing knowledge on the ethno-botanical value of these resources among 317 registered informants. Data on socio demographic characteristics and uses of these plant resources was collected based on oral interview using Kobo Collect tool and a well-structured questionnaire from 11 ethnic groups. Quantitative analysis techniques including Multiple Correspondence Analysis (MCA), Hierarchical Clustering (HCPC) and beta-regression (beta-reg)) were performed to evaluaterelative usefulness of different tree organs and the extent to which quantitative indexes give similar results. Results revealed three clusters with diverse uses of D. mespiliformis. The main uses categories of African ebony were food-fodder, medicinal, construction and magico-religious. The results showed also significant difference in use between ethnic groups, generations and socio-professional categories (P < 0.05). However, gender, religion and educational background of informants were not a determinant of local knowledge (P > 0.05). In addition, diseases treated with D. mespiliformis werefever, dressing wound, malaria and infertility. Our findings suggest that local availability of D. mespiliformis should prioritize the fruit and the wood which are the most valued parts of the plant. In order to fully explore the plant’s potential, this resource needs development of integrated cultivation approach, safety evaluation and detailed ethno-pharmacological studies because it is not excluded that interesting medicinal properties setting in light by research permit to finalize new drug.
