Estimation of Economic Value of Agroforestry Systems at the Local Scale in Eastern Sudan

引用

Journal of Geoscience and Environment Protection 2015年第9期3卷 38-56页

The objective of this paper is to institute farmers’ own perceptions of the on-and off-farm benefits of agroforestry systems (AFS). Using use value approach, this paper presents empirical evidence on the use values of three types of AFS practiced by the refugees and their hosting communities in Eastern Sudan. The total economic value (TEV) was applied as a framework to estimate the ecosystem values of AFS under study. Goods values were estimated using specific market values, while the services values were qualitatively described according to local perceived values of the local communities. Perceived TEV of AFS includes marketable and non-marketable goods and services. The main direct marketable and sustainable high value products include: food, cash crops, firewood, gum, fodder, NTFPs medicine, fodder, and honey. The valuation results reveal that AFS in the project sites have significantly contributed to the livelihoods of the local communities. Overall, the average net direct-use value of marketable products across all sites was estimated at 7,346,000.0 SDG (1,335,636.36 US$) HH/annum. Gum Arabic alone accounted for 38%, followed by sorghum grain and fodder 35%, and cash crops (sesame) 18%. This value would be many time higher if other indirect values (non-marketable) services such as shade, aesthetic and recreation, environmental protection, biodiversity and carbon sequestration are quantified. The goods and services mentioned above provide sustainable income to the farmer directly and viable benefits to the region indirectly. Hence, AFS in the study sites shows the way to reconcile two conflicting goals: short-term food and livelihood needs with long-term environmental conservation and improvement. The study provides evidence that the high local perceived values of AFS in the study sites constitute a central means of livelihood, whereas its contribution to the local economy. The study stresses the need to quantify the monetary values of non-marketed products to c

Ecological Sustainability of Detar (<i>Detarium senegalense</i>J. F. Gmel) in Togo (West Africa)

引用

American Journal of Plant Sciences 2019年第3期10卷 417-432页

作者： Fifonsi Ayélé Dangbo Kossi Adjonou Kouami Kokou Juergen Blaser Forest Research Laboratory Faculty of Sciences University of Lome Lome Togo Forest and Climate Change Department Bern University of Applied Science (HAFL) Bern Switzerland

Detarium senegalense J. F. Gmel., of the family of Fabaceae is one of the most exploited tree species in Togo. However, there are only few scientific studies on the distribution of this specie. This study is a contribution to the promotion of multi-purpose tree species in Togo with particular emphasis on a better knowledge of Detarium senegalense. It provides data on the ecology of the specie and his state of regeneration. The data on the specie are based on sample plots in the areas identified as hosts of the specie in Togo. A total of 77 circular plots of 1000 m2 (17.8 m radius) were established in ecological zones II, IV and V of Togo. The dendrometric parameters identified are: the total height and diameter at breast height (DBH) of Detarium senegalense and of all species found in each plot. Detarium senegalense trees of DBH < 10 cm are considered as potential regenerations. Detarium senegalense is more abundant in zones IV (forest area), followed by zone II. In zone V, Detarium senegalense is located only in the forest of “Have”. The structure of Detarium senegalense has a bell-shaped distribution with predominance of trees with large and intermediate diameters ranging between 30 and 70 cm. Trees of small DBH (Detarium senegalense occurs. This indicates a low regeneration rate of the specie. However, the structure of all species inventoried has a negative exponential distribution with predominance of small diameter trees. The sustainable management of Detarium senegalense in the forest can only be secured through a sustainable harvesting of seeds and actives promotion of natural regeneration.
